Description

Laser beam irradiation apparatus for lipolysis {Apparatus for irradiating laser beam}

The present invention relates to a laser beam irradiation apparatus for lipolysis, and more particularly, it is possible to effectively treat obesity by decomposing fat cells without side effects such as skin damage, bleeding, and pain, as well as heat spreading around the laser beam during irradiation. The present invention relates to a laser beam irradiation apparatus for lipolysis having excellent heat dissipation efficiency while preventing temperature increase of the laser diode.

As a medical procedure for treating obesity in which an abnormally large amount of fat in the body including subcutaneous fat is inhaled, so-called liposuction which inhales subcutaneous fat in areas where fat is accumulated at a strong negative pressure and corrects its shape is common. The laser is used as an aid to inhalation.

Currently used liposuction using laser is to put the optical fiber in the cannula and insert it into the adipose tissue, irradiate the laser through the optical fiber, and then inhale the liposuction and administer the local anesthetic fluid to the fat layer. The low level laser can be irradiated for a certain time to induce the destruction of fat cells and can be divided into the external laser irradiation method of liposuction.

However, in the case of the internal laser irradiation method, there is a lot of difficulty because the skin is incision and bleeding, fatigue and swelling, pain, bruising and bleeding after the procedure are involved.

On the other hand, as an example of a laser beam irradiation apparatus used for an external laser irradiation method, a lipolysis apparatus using a low power laser is disclosed in Korean Patent No. 10-0653441.

That is, as shown in FIG. 1, the laser generating unit 15 includes a plurality of laser diodes 12 electrically connected to the PCB 11 on a contact plate body 13 in which a plurality of transparent windows or lenses 14 are uniformly arranged. ) And a frame 20 to which the laser generating unit 15 is mounted and is in close contact with the skin.

In addition, the contact plate body 13 is formed of a heat sink plate for radiating heat generated by the laser diode 12.

However, in the conventional lipolysis device, the frame 20 tightly seals the laser generation unit 15 and the contact plate body covers the surface of the transistor outline type laser diode 12. Since the heat dissipation is performed, the contact plate 13 may not function properly, and the heat generation may be severe, and thus the output of the laser diode 12 may not be stably achieved, and the lifespan is extremely shortened. The rise of the temperature of the phenomenon occurs that hinders the laser operation, due to this there is a problem that the lipolysis effect is inevitably lowered.

In other words, the laser diode has a Fermi-Dirac function that determines the distribution probability according to the energy of electrons and holes when the temperature rises due to the temperature-sensitive characteristic, and thus the electrons in the unit energy band are widely distributed. The gain of the laser given as a function of the difference in hole density function is reduced, the hot carrier overflow is increased, and Auger recombination is increased.

This phenomenon reduces the internal gain of the laser diode, increases the internal loss, and decreases the injection efficiency of electrons, thereby degrading the characteristics of the current output optical power of the laser diode.

In particular, the transistor outline type laser diode package has a structure in which electrode pins protrude to the bottom thereof, and thus requires a special design to prevent temperature rise by contact with air.

Accordingly, the present inventors can focus on solving the above-described problems and problems, and quickly and smoothly dissipate heat generated from the laser diode, and further prevent the temperature rise of the laser diode more effectively, thereby significantly improving the performance of the laser diode. While devoting to study the development of the laser beam irradiation apparatus was devised and completed the present invention.

It is therefore an object of the present invention to provide a laser beam irradiation apparatus for lipolysis that can quickly and smoothly dissipate heat generated from a laser diode.

It is another object of the present invention to provide a laser beam irradiation apparatus for lipolysis that enables the output of a laser diode to be stably maintained.

In order to achieve the above object, the present invention provides a laser beam module comprising a plurality of laser diode packages mounted on a printed circuit board, and a heater sink mounted while surrounding the base of the laser diode package; A housing containing the laser beam module; It is installed in the front of the housing at a predetermined interval with the heater sink, and provides a laser beam irradiation apparatus for lipolysis comprising a plate formed with a laser irradiation hole corresponding to the window of the laser diode package.

The present invention also provides a laser beam irradiation apparatus for lipolysis, wherein a heat dissipation flow path is formed between the laser beam module and the plate of the present invention.

In addition, the air inlet is formed on one side of the housing of the present invention, there is provided a laser beam irradiation device for lipolysis formed air outlet on the other side.

In addition, the present invention provides a laser beam irradiation apparatus for fat decomposition provided with a blowing fan for forcibly circulating and discharging air in the air outlet.

In addition, the present invention provides a laser beam irradiation apparatus for lipolysis, wherein an air barrier film is formed between the air inlet and the air outlet.

According to the present invention having the above-mentioned means and configuration, the air inlet, the air outlet, and the heat dissipation passage are formed to dissipate and circulate the external air to force the discharge of the air. Effective heat dissipation can increase the laser diode's operating efficiency and stabilize its output.

In addition, since the heater sink is formed in a form surrounding the base of the laser diode package, the present invention can maximize the heat dissipation efficiency by maintaining the laser diode temperature low.
