Description

LASER IRRADIATION DEVICE FOR ORAL TREATMENT AND MANUFACTURING METHOD THEREOF

The present invention relates to an oral treatment laser irradiation device having a novel mouthpiece structure for facilitating laser treatment of an area vulnerable to oral mucositis in the oral cavity, and a method for manufacturing the same.

In general, low-level laser therapy (LLLT) is a treatment method that promotes spontaneous healing effects on damaged areas of the body by photobiomodulation mechanisms that control bioactivity using laser light. LLLT technology is used in various fields such as skin and beauty, ophthalmology, dentistry, pain relief, wound treatment, neurology, and oncology. In dentistry in particular, laser irradiation devices are used for teeth whitening, oral pain relief, and oral mucositis.

Meanwhile, there are frequent cases of patients with moderate to severe oral mucositis after anticancer radiation therapy or anticancer chemotherapy. Recently, many papers have reported results of low-power laser treatment on animal models that induced oral mucositis, showing anti-inflammatory effects such as wound healing, collagen synthesis, and neutrophil reduction.

Korean Patent Publication No. 10-2013-0057692, "Oral treatment mouthpiece and oral treatment device having the same," and Registration Patent No. 10-1554721, "Oral light irradiation device," propose a treatment device that uniformly irradiates a laser beam toward the inside of the oral cavity while the patient is biting the mouthpiece. However, the above prior documents are configured to transmit the laser light into the oral cavity by spreading the laser beam using a beam expander or by transmitting the laser light into the oral cavity by light reflection using a reflection unit, so there was a problem that the intensity of the laser light was weak and the energy was weakened in the process of the laser reaching the area of inflammation, making it difficult to cause damage to a living body.

Typically, oral mucositis frequently occurs after anticancer treatment in vulnerable areas of the oral cavity, such as the oral vestibule, periodontium, sublingual glands, and tonsils. While these vulnerable areas are located deep in the oral cavity, the above prior art had a structural problem in which the amount of light was concentrated in the front part of the oral cavity and it was difficult for the light to reach the vulnerable areas with high intensity, which limited the treatment of oral mucositis. In addition, the above prior art irradiated light with a single wavelength, and there was a problem in that the light did not penetrate deeply to the desired area as its energy was lost during the process of penetrating the living body.

In addition, the most important point in the laser irradiation device for oral treatment is that the laser light should be irradiated directly to the patient's oral mucositis area and that there should be little loss in the light path.

Referring to Figures 1 to 5, the oral treatment laser irradiation device of the present invention is composed of a main body (100), a cable (500), and a mouthpiece (200).

Referring to FIGS. 1 and 5, the main body (100) has a power supply unit (180) and a control unit (800) therein. For example, the power supply unit (180) may be a battery. The battery may be a dry cell that can be stored in the main body (100) or a rechargeable secondary battery. As another example, the power supply unit (180) may include a converter that receives commercial AC power and converts it into DC power. Although not shown, a battery storage unit, a charging port for connecting a charger for charging the secondary battery, or a connection jack for connecting to an adapter connected to a commercial AC power source are installed on the back surface of the main body (100). The control unit (800) outputs an operation signal to the LED driver (810), and causes the laser diodes to operate in pulse mode or continuous wave mode by the LED driver (810) to irradiate an inflammatory area in the oral cavity.

The laser diodes described below may be three-wavelength laser diodes configured in a single chip form including a first laser diode (822) having a wavelength of 650 nm to 690 nm, a second laser diode (824) having an intrinsic wavelength of 850 nm, and a third laser diode (826) having a wavelength of 890 nm to 930 nm. Preferably, the first laser diode (822) may have a wavelength of 670 nm, the second laser diode (824) may have a wavelength of 830 nm, and the third laser diode (826) may have a wavelength of 910 nm.

Referring to FIG. 1, the front of the main body (100) is provided with an operation button (110), a mode selection button (120), a time selection button (130), an intensity selection button (140), a power button (150), a display means (160), and an emergency stop button (170).

The laser light irradiation mode has four modes: pulse output mode, first continuous wave mode, second continuous wave mode, and third continuous wave mode. Each time the mode selection button (120) is pressed, the mode is changed sequentially.

The time selection button (130) is a button for selecting the laser light irradiation time. For example, each time the button is pressed, the operation time increases by 10 minutes, and if the time selection button (130) is pressed again after selecting 60 minutes of operation, it changes to 10 minutes of operation. The intensity selection button (140) is a button for gradually adjusting the laser output intensity of the selected operation mode.

The power button (150) is a button for selecting power on and off of the entire device. The display means (160) is a means for displaying the currently selected laser operation mode, operation time, and output intensity to the user. The emergency stop button (170) is a button for immediately stopping the operation of the device and cutting off the power in an emergency situation.

Referring to FIG. 1, a front side area of the main body (100) is sunken backward to form a mounting space capable of mounting multiple mouthpieces (200), and a hanging groove (190) is provided so that the mouthpieces (200) can be hung and fixed. A cable (500) connects the main body (100) and the mouthpiece (200) to supply operating power of the main body (100) to each of the multiple laser diodes installed in the mouthpiece (200).

Referring to FIG. 2, the mouthpiece (200) is composed of a base frame (300), an LED strip (400), and a light-emitting cover (210, 230).

The base frame (300) has a mounting groove (334, 336, 362, 364, 366, 372, 374, 376) and a cut portion (332) in which a plurality of laser diodes are mounted, a tongue fixing frame (330) formed to be convex upward so that the tongue can be inserted into the space below it, and a tooth mounting portion (350) on which upper and lower teeth are mounted.

The LED strip (400) has a strip shape in which a plurality of laser diodes are installed by being inserted into the mounting grooves (334, 336, 362, 364, 366, 372, 374, 376) and the cutout (332) and are installed on a flexible circuit board.

The connection hole (310) formed at the end of the base frame (300) is a portion into which the end of the cable (500) is inserted, and the wires of the cable (500) are connected to the LED strip (400) within the connection hole (310). The LED strip (400) is composed of a double-sided flexible circuit board, and the strips of the flexible circuit board and the laser diodes installed on the flexible circuit board are fitted into grooves and holes formed in the base frame (300) to fix the position of the LED strip (400).

Referring to FIGS. 3 and 4, the LED strip (400) has a structure in which a plurality of branch strips branch and extend from a thick film portion in the central portion, and a plurality of laser diodes are installed on each of the branch strips. Since the LED strip (400) is formed as a double-sided flexible circuit board, and a plurality of laser diodes are installed on the front and back surfaces, respectively, as shown in FIGS. 3 and 4, it is possible to irradiate laser light to the palate and the tongue, respectively, while configuring the tongue fixing frame (330) of the base frame (300) as a single frame.

A strip center mounting groove (320) is formed adjacent to the connection hole (310) of the base frame (300). Then, the strip center support (420) at the center of the LED strip (400) is folded and fitted into the strip center mounting groove (320).

Referring to FIG. 3, an LED strip (400) has an arc-shaped tonsil branch strip (445) formed at one end with respect to a central support member (420) of the strip, and a horseshoe-shaped sublingual gland branch strip (480) formed at the other end. In the tonsil branch strip (445), a tonsil irradiation laser diode (440) is installed at a predetermined interval to irradiate a tonsil area of a human body with laser light. In the sublingual gland branch strip (480), a sublingual gland irradiation laser diode (482) is installed at a predetermined interval to irradiate a sublingual gland area of a human body with laser light.

A first transverse strip (430) and a second transverse strip (431) are formed transversely between the strip center support (420) and the tonsil branch strip (445). A laser diode (436) for irradiating the lateral palate of a human body, which irradiates laser light toward the side of the palate of the human body, is installed in the first transverse strip (430). A laser diode (434) for irradiating the front palate of the human body, which irradiates laser light toward the front of the palate of the human body, is installed between the first transverse strip (430) and the strip center support (420).

Between the central support strip (420) and the sublingual gland branch strip (480), two rows of periodontal branch strips (450) are formed with both ends meeting. A plurality of periodontal irradiation laser diodes (452) are installed on the periodontal branch strips (450) to irradiate laser light to the periodontal region of the human body.

Referring to FIG. 4, laser diodes (462, 464, 466, 472, 474, 476) for irradiating the oral vestibule of a human body are installed in the strips protruding outward from the periodontal branch strip (450). In addition, six tongue irradiation laser diodes (432) for irradiating laser light to the tongue of a human body are installed in the vicinity of the first transverse strip (430), the second transverse strip (431), and the central support portion (420) of the strip.

The process of assembling and installing the laser diodes described with reference to FIGS. 3 and 4 to the base frame (300) is described as follows.

On the tongue fixing frame (330) of the base frame (300), a mounting groove (334) for anterior palate irradiation and a mounting groove (336) for lateral palate irradiation are concavely formed, and a tongue irradiation cutout (332) is cut and formed. In the mounting groove (334) for anterior palate irradiation, a laser diode (434) for anterior palate irradiation of an LED strip (400) is installed facing upward and fitted into the mounting groove (334) for lateral palate irradiation. In the mounting groove (336) for lateral palate irradiation, a laser diode (436) for lateral palate irradiation of an LED strip (400) is installed facing upward and fitted into the mounting groove (336) for lateral palate irradiation. In the tongue irradiation cutout (332), a tongue irradiation laser diode (432) of an LED strip (400) is installed facing downward. That is, in the mouthpiece structure of the present invention, the tongue fixation frame (330) is configured as a single frame, and the upper palate and the lower tongue can be treated simultaneously by irradiating them with laser light using a double-sided flexible circuit board.

Referring to FIG. 2, the tongue fixing frame (330) of the base frame (300) is bent at an obtuse angle toward the tonsils in the oral cavity to form a folding surface (340) for tonsil irradiation. Then, the tonsil branch strip (445) of the LED strip (400) is assembled by being secured to the folding surface (340) for tonsil irradiation. Accordingly, the laser diode (440) for tonsil irradiation can irradiate laser light in close proximity to the tonsils of the human body.

Although not depicted in FIG. 2, a mounting portion is formed at the bottom of the base frame (300) on which a sublingual gland branch strip (480) is mounted. By mounting and assembling the sublingual gland branch strip (480) here, the sublingual gland irradiation laser diode (482) can irradiate laser light in close proximity to the sublingual gland of a human body.

In addition, although not depicted in Fig. 2, a plurality of periodontal examination mounting grooves are formed in two rows (respectively, upper teeth periodontal row and lower teeth periodontal row) on the outer periphery of the base frame (300) (i.e., the opposite side of the side facing the tooth mounting portion (350). In addition, the periodontal branch strip (450) of the LED strip (400) described above is assembled into the periodontal examination mounting groove. Accordingly, the periodontal examination laser diode (452) can irradiate laser light in close proximity to the periodontium of a human body.

Referring to FIG. 2, the upper and lower surfaces of the wall portions installed around the tooth mounting portion (350) of the base frame (300) are formed with first oral vestibular examination mounting grooves (362, 372) that are concavely formed to have installation surfaces bent at a first angle toward the oral vestibule located on the upper and lower molars of the human body. The first angle is, for example, 90 degrees with respect to the vertical wall. The first left oral vestibular examination mounting groove (362) and the first right oral vestibular examination mounting groove (372) are formed to be symmetrical left and right with respect to the longitudinal center line of the mouthpiece (200). And, a first left oral vestibular examination laser diode (462) of an LED strip (400) is installed in the first left oral vestibular examination mounting groove (362), and a first right oral vestibular examination laser diode (472) is installed in the first right oral vestibular examination mounting groove (372).

A second oral vestibular irradiation mounting groove (364, 374) is formed on the upper and lower surfaces of the wall so as to have an installation surface bent at a smaller angle than the first angle toward the oral vestibule located on the upper and lower canine sides of the human body. The second angle is, for example, 60 degrees with respect to the vertical wall. The second left oral vestibular irradiation mounting groove (364) and the second right oral vestibular irradiation mounting groove (374) are formed to be symmetrical on both sides with respect to the longitudinal center line of the mouthpiece (200). In addition, a second left oral vestibular irradiation laser diode (464) is installed in the second left oral vestibular irradiation mounting groove (364), and a second right oral vestibular irradiation laser diode (474) is installed in the second right oral vestibular irradiation mounting groove (374).

A third oral vestibular irradiation mounting groove (366, 376) is formed on the upper and lower surfaces of the wall so as to have an installation surface bent at a smaller angle than the second angle toward the oral vestibule located on the upper and lower front teeth of the human body. The third angle is, for example, 30 degrees with respect to the vertical wall. The third left oral vestibular irradiation mounting groove (366) and the third right oral vestibular irradiation mounting groove (376) are formed to be symmetrical on the left and right based on the longitudinal center line of the mouthpiece (200). In addition, a third left oral vestibular irradiation laser diode (466) is installed in the third left oral vestibular irradiation mounting groove (366), and a third right oral vestibular irradiation laser diode (476) is installed in the third right oral vestibular irradiation mounting groove (376).

In this way, since the oral vestibular examination mounting grooves (362, 372) on the molar side, the oral vestibular examination mounting grooves (364, 374) on the canine side, and the oral vestibular examination mounting grooves (366, 376) on the incisor side each have installation surfaces at different angles, it is possible to irradiate oral mucositis occurring in the oral vestibular region with very close direct light according to the oral structure.

Referring to Fig. 2, the light-transmitting cover (210, 230) is coupled to the outside of the LED strip (400) and transmits the laser light emitted from the laser diode. The light-transmitting cover (210, 230) has a structure in which the upper light-transmitting cover (210) coupled to the upper side of the LED strip (400) and the lower light-transmitting cover (230) coupled to the lower side are assembled in mutual contact.

The upper light-transmitting cover (210) and the lower light-transmitting cover (230) are formed of a silicone material. In addition, as will be described later with reference to FIG. 7 and below, a liquid light-transmitting resin material is injected into the interior of the upper light-transmitting cover (210) and the lower light-transmitting cover (230) and then cured. The liquid light-transmitting resin material is liquid silicone that has almost the same light transmittance as the light-transmitting covers (210, 230) after curing. By injecting and curing the liquid silicone between the upper light-transmitting cover (210) and the lower light-transmitting cover (230) in this way, the LED strip (400) can be firmly fixed to the base frame (300), and laser light can be irradiated to the affected area with high light transmittance. Preferably, by forming a plurality of exhaust holes in the upper transparent cover (210) and the lower transparent cover (230), the liquid silicone is discharged to the outside through the exhaust holes during the process of pressing the transparent cover (210, 230) against the base frame (300), thereby solving the problem of air bubbles being generated inside the transparent cover (210, 230) and thus reducing the light transmittance.

The upper transparent cover (210) has a cable insertion port (212) into which a cable (500) is inserted at an end of a connection port (214) that protrudes outside the lips when the user bites the mouthpiece (200) with his or her teeth. The connection port (214) has a length that can extend a sufficient length outside the lips when the patient bites the mouthpiece (200). The tongue fixing convex portion (216) is formed to be convex upwardly corresponding to the upper surface of the tongue fixing frame (330) of the base frame (300). The U-shaped upper oral vestibular insertion portion (218) that protrudes upwardly of the upper transparent cover (210) is inserted into the upper oral vestibular space between the upper teeth and the upper lip. The upper tooth mounting portion (220) that is formed to be recessed inwardly along the upper oral vestibular insertion portion (218) is a portion where the ends of the teeth of the upper teeth are mounted. The mouthpiece (200) is stably supported in the upper part of the patient's oral cavity by the upper oral vestibular insertion part (218) and the upper tooth anchorage part (220).

The lower light-transmitting cover (210) has a cable insertion port (232) into which a cable (500) is inserted at an end of a connecting port (234). The tongue fixing convex portion (236) is formed to be convex upwardly corresponding to the lower surface of the tongue fixing frame (330) of the base frame (300), and the upper part of the human tongue is supported on the lower surface of the tongue fixing convex portion (236) to fix the position of the tongue during treatment. The U-shaped lower oral vestibular insertion portion (238) protruding downward from the lower light-transmitting cover (230) is inserted into the lower oral vestibular space between the lower teeth and the lower lip. The lower tooth fixation portion (240) formed to be recessed inwardly along the lower oral vestibular insertion portion (238) is a portion where the ends of the teeth of the lower teeth are fixed. The mouthpiece (200) is stably supported in the lower part of the patient's oral cavity by the lower oral vestibular insertion portion (238) and the lower tooth anchorage portion (240).

FIG. 6 is a drawing exemplifying an oral mucositis vulnerable area that can be simultaneously treated with laser using the mouthpiece of the present invention.

As shown in the oral cross-section of Fig. 6, the areas where oral mucositis frequently occurs are the upper oral vestibule (702), the upper incisor periodontium (704), the upper canine periodontium (706), the upper molar periodontium (708), the tonsils (710), the lower oral vestibule (712), the lower incisor periodontium (714), the lower canine periodontium (716), the lower molar periodontium (718), and the sublingual gland (720). In addition, these areas correspond to vulnerable areas that are not well treated by conventional oral treatment laser irradiation devices.

Since the oral treatment laser irradiation device of the present invention has the above-described mouthpiece (200) structure, it can perform laser treatment by bringing the laser diode as close as possible to the deep part of the oral cavity while covering all the areas vulnerable to oral mucositis as described above.

Here, the control unit (800) may include a microprocessor unit and controls the operation of the laser diodes in a unified manner according to commands programmed in the memory of the microprocessor unit.

The control unit (800) operates in one of the following modes: a pulse output mode in which the first laser diode (822) of 670 nm, the second laser diode (824) of 830 nm, and the third laser diode (826) of 910 nm are alternately output in a pulse form, a first continuous wave output mode in which the first laser diode (822) is output in a continuous wave form, a second continuous wave output mode in which the second laser diode (824) is output in a continuous wave form, and a third continuous wave output mode in which the third laser diode (826) is output in a continuous wave form, depending on the input of the mode selection button (120).

The control unit (800) can set the pulse width of the second laser diode (824) to a time that is three times longer than the pulse widths of other laser diodes in the pulse output mode. For example, the control unit (800) sets the pulse width of the first laser diode (822) having a wavelength of 670 nm to "250us±5%", the off time to "1,350us±5%", and the repetition rate to 625Hz±5%. In addition, the control unit (800) sets the pulse width of the second laser diode (824) having a wavelength of 830 nm to "950us±5%", the off time to "650us±5%", and the repetition rate to 625Hz±5%. Finally, the third laser diode (826) with a wavelength of 910 nm is set to the same pulse width as the first laser diode (822) at "250us±5%", off time at "1,350us±5%", and repetition rate at 625Hz±5%. It is repeatedly output with a pause of 50us between each wavelength.

When the first laser diode (822) operates in pulse mode, the 670 nm laser light causes microscopic bio-damage to the epidermis and dermis. The second laser diode (824) operates in pulse mode for a longer period of time compared to other laser diodes, and the 830 nm wavelength laser penetrates deep into the subcutaneous tissue through the dermis layer to treat inflammation. Finally, the third laser diode (826) penetrates into the dermis layer but allows the inflamed area to have a sufficient spontaneous recovery period. By operating the three-wavelength laser in pulse output mode in this way, the photobiomodulation mechanism can be sufficiently expressed in the oral mucositis area.

FIG. 7 is a flow chart illustrating a method for manufacturing a laser irradiation device for oral treatment according to the present invention, and FIGS. 8 to 10 are cross-sectional views illustrating a process for manufacturing a laser irradiation device for oral treatment according to the present invention. Referring to FIGS. 7 to 10, a method for manufacturing a laser irradiation device for oral treatment according to the present invention will be specifically described as follows.

First, as described above, a base frame (300) is formed to have a tongue fixing frame (330) and a tooth anchoring portion (350) (ST110). The detailed structure of the base frame (300) is as described with reference to FIGS. 1 to 5. The cross-sectional view of FIG. 8 is a cross-sectional view taken transversely of the base frame (300). Although the first left oral vestibular examination anchoring groove (362) and the first right oral vestibular examination anchoring groove (372) at the edge are not shown because they are cut off, it can be confirmed that the second left oral vestibular examination anchoring groove (364), the third left oral vestibular examination anchoring groove (366), the second right oral vestibular examination anchoring groove (374), and the third right oral vestibular examination anchoring groove (376) are located vertically.

Next, the LED strip (400) as shown in FIGS. 4 and 5 is assembled to the base frame (300) (ST120). The cross-sectional view of FIG. 9 shows a state in which the LED strip (400) is assembled to the base frame (300). It can be confirmed that the central tongue irradiation laser diode (432) is installed facing downward, and the palate front irradiation laser diode (434) is installed facing upward. In addition, it can be confirmed that the second left oral vestibular irradiation laser diode (464) installed in the second left oral vestibular irradiation mounting groove (364) is installed at a gentler incline compared to the third left oral vestibular irradiation laser diode (466) installed in the third left oral vestibular irradiation mounting groove (366). This will enable laser light to be irradiated over a wide area more closely to the mucositis occurring in the oral vestibule, as the oral vestibule near the canines of the human body has a gentler slope than the oral vestibule near the incisors.

Next, as illustrated in the cross-sectional view of Fig. 10, a liquid light-transmitting resin material (e.g., liquid silicone) is injected into the interior of the upper transparent cover (210) and the lower transparent cover (230) (ST130). The upper transparent cover (210) and the lower transparent cover (230) can be manufactured by injection molding a silicone material to have a shape as described with reference to Fig. 2. At this time, a plurality of discharge holes (250) are formed in the upper transparent cover (210) and the lower transparent cover (230) so that the liquid silicone can be discharged to the outside as illustrated in an enlarged manner in Fig. 10. Preferably, the discharge holes (250) are microscopic holes that allow the liquid silicone to overflow due to pressure from the pressing process, and are formed at a position off the optical axis of the laser diode as illustrated in Fig. 10.

And the upper transparent cover (210) and the lower transparent cover (230) are joined by pressing them up and down with respect to the base frame (300) (ST140). Next, in the pressing process, the liquid silicone overflow that escapes to the outside through the discharge hole (250) of the upper transparent cover (210) and the lower transparent cover (230) is removed (ST150), and the liquid silicone inside the transparent cover is cured (ST160). The curing of the liquid silicone can be performed by any one of natural curing using a curing agent, thermal curing, and UV curing.

The invention disclosed above can be modified in various ways without damaging the basic idea. In other words, the above embodiments should all be interpreted as illustrative, not restrictive. Therefore, the scope of protection of the present invention should be determined by the attached claims, not the above-described embodiments, and if the elements defined in the attached claims are replaced with equivalents, they should be considered to fall within the scope of protection of the present invention.
