Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a socket extending apparatus for extracting broken dental roots,

The present invention relates to a socket extension mechanism for fractured root extraction, and more particularly to a socket extension mechanism for a fractured root extraction that facilitates entry of a device for extracting a fractured root remaining in the socket.

Surgical tooth extraction is one of the procedures commonly practiced in dentistry. It is a procedure that is commonly performed in the dentistry. When the alveolar bone is absorbed remarkably, the teeth are agitated, the chronic inflammation is present in the apex, Of the teeth are removed and the root is left alone, the conservative treatment or prosthetic treatment is not possible, the root fracture is caused by trauma, the disorder is caused by the position abnormality, It means surgery.

In general, surgical extraction uses an extraction forcep or an elevator or both at the same time, even if it is a single root that extends from one crown, It is prone to fracture in the dislocation process if it is divided into two, beginning with root and proceeding with root apex.

In the case of multi-root, the root of each root is thinner than that of single root, and the septum is filled between the roots, so that the risk of fracture tends to be high.

Anatomically, root fractures are often seen in premolar premolars with these features. The formation of a space for the use of a luxator blade around the root can be seen in the root of the socket It is often difficult to obtain the operation field of the surgeon and the approach of the instrument is difficult because of the close root fracture.

For this reason, the dentists have been baffled by sudden accidents and have been exposed to prolonged periods of severe procedures and medical accidents.

Commonly used instruments to remove broken roots include a thin, pointed root tip picker that fits a narrow fissure between the root and the adjacent alveolar bone, It is used for the purpose of luxation.

At this time, the blade of the picker digs between the root and the alveolar bone to form a narrow gap to form a strong fissure which can serve as a lever, and at the same time, the root must be dislocated. In clinical practice, This was not easy because of the disadvantage of the direction.

The root tip picker may puncture a thin bone plate if its tip is sharp and gives excessive force in the wrong direction. When the root apex and the maxillary sinus are close together, It may happen that the sinus is pushed together with the root while perforating the sinus.

In addition, when the tip is applied to the root portion of the root instead of the alveolar bone during use, the end of the tooth is scarred and the original function is lost when reused.

In addition, there has been an attempt to insert a screw or a file having a thread form into a pulp canal to integrate it with the root and use a forceps.

However, if the root is not fully dislocated before the tooth breaks, it is difficult to retrieve it, and finding the pulp canal in the middle of the broken small root is very difficult unless the field of view is secured, It is not easy to find the right lever.

Disclosure of the Invention The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a socket extension for a fractured root extraction that is easy and quick in a narrow and deep socket that minimizes visibility, The purpose is to provide a mechanism.

According to another aspect of the present invention, there is provided a socket extending mechanism for extracting a tooth root remaining in a socket of an alveolar bone,

A plurality of side blades for cutting the surface of the alveolar bone on a side surface of the truncated cone having a lower diameter than an upper portion of the truncated cone,

And a rotation bar having one end coupled to the edge block and the other end connected to a rotation motor,

Wherein a bottom diameter of the edge block is formed to be larger than a diameter of a fractured surface of the extracted tooth, and a flat portion having no edge is formed at a central portion of a bottom portion of the edge block.

Further, the present invention is characterized in that a discharge groove is formed between the side edges for discharging bleeding occurring when the alveolar bone is cut, and a discharge hole penetrating the upper surface of the edge block from the discharge groove is further formed.

Further, the present invention is characterized in that an annular blade projecting in an annular shape is further formed on a bottom edge of the edge block.

The socket 31 expansion mechanism 40 of the embodiment of the present invention does not cut any more as the flat surface portion 41c on which the edge of the bottom portion of the edge block 41 is not formed is in contact with the upper surface portion of the rootbody 100 An inexperienced dentist also enables the use of the expansion device 40 in a stable manner.

In addition, as the edge block 41 descends, the top portion A of the root portion 100 of the root portion 100, which has been sharply broken, is dulled so that the upper portion of the root portion 100 has a thickness, Thereby facilitating the extraction of the tooth root 100 so that sufficient leaning force can be exerted upon extraction by the instrument.

The socket 31 expansion mechanism 40 of the embodiment of the present invention allows the edge block 41 having the blades on the side and bottom portions to be rotated while being inserted into the socket 31 so that the wall surface of the alveolar bone 30 is cut and expanded Thereby facilitating the formation of the annular groove 33 between the root roots 100 and the alveolar bone 31 and allowing the generated blood to be smoothly discharged through the discharge groove 41d to cut the surface of the alveolar bone 30 Thereby increasing the precision.

Further, since the discharge hole 41e penetrating the upper surface of the edge block 41 from the discharge groove 41d is formed, it is possible to more reliably discharge the bleeding blood.

An annular blade 41f protruding in an annular shape is formed at the lower edge of the edge block 41 so that the socket 31 is extended and the annular groove 33 is formed between the root 100 and the alveolar bone 31, So that the use of the annular groove forming mechanism 50 can be excluded.

As shown in FIG. 1A and FIG. 1B, the tooth root 100 occurs when the teeth are too cavitated or broken in an accident, or when the teeth 110 are broken during extraction. The socket expansion mechanism can secure the space of the socket so that the extraction mechanism for root extraction can easily access to the root, and has a thickness at the upper part of the sharp root, By preventing the upper part of the root from being broken, the extraction mechanism can exert a sufficient leverage force.

In particular, the expansion mechanism of the embodiment of the present invention allows the annular groove forming mechanism 50 of FIG. 1E to be easily inserted into the socket 31, and that the present applicant has proposed the "root (Fig. 4) for expanding the socket so that it can easily enter between the root roots and the alveolar bone.

1B, the socket 31 has a shape in which the diameter thereof becomes smaller as it gets deeper into the alveolar bone 30, and the broken root 100 has a bent socket 31, So that entry of the extraction mechanism becomes difficult.

The expanding mechanism 40 of the embodiment of the present invention stably and straightly forms the curved socket 31 up to the upper surface portion of the root 100 so that the extraction mechanism can easily enter.

Referring to FIGS. 1C and 2, the socket expanding mechanism 40 of the embodiment of the present invention includes a plurality of side blades (not shown) for cutting the surface of the alveolar bone 30 on the side surface thereof, 41a are formed at regular intervals and an edge block 41 having a lower surface 41b is formed on a lower surface thereof and a rotary bar 42 connected to the edge block 41 and connected to a rotary motor ).

A planar portion 41c having no blades is formed at the center of the bottom surface of the edge block 41. [

Between the side blades 41a, a discharge groove 41d for discharging bleeding occurring when the alveolar bone 30 is cut is formed.

On the other hand, the bottom portion diameter of the edge block 41 is about 1 mm larger than the diameter A of the fracture surface of the extracted tooth 110. This makes it possible for the annular groove forming mechanism 50, which will be described later, to enter the socket 31 to easily form the annular groove 33 around the root 100.

As shown in FIGS. 1A and 1C, in a state where the root 100 remains due to breakage of the tooth 110 during extraction, the edge block 41 of the expansion mechanism 40 is rotated to the socket 31 The wall surface of the alveolar bone 30 is cut and expanded as shown in FIG. 1D.

The hemispherical blood generated at this time is smoothly discharged through the discharge groove 41d and the flat portion 41c on which the lower edge of the edge block 41 is not formed contacts the upper surface of the root 100, And the entry of the edge block 41 toward the end of the socket 31 is stopped.

The edge block 41 is lowered in the depth direction of the socket 31 and the surface of the alveolar bone 30 is cut to expand the socket 31 so that the flat surface portion 41c contacts the upper surface portion of the root 100 So that a dentist who is not experienced can stably use the expanding mechanism 40. [0051]

1A and 1B, when a tooth 110 is fractured, an inclined surface 100a is typically formed on a tooth root 100 to form an attachment A, The attachment (A) broken after the extraction of the root (100) is left in the socket (31).

Therefore, it is troublesome to remove the attachment (A) remaining in the socket (31) after extracting the root (100) from the socket (31).

Further, when the attachment (A) of the root roots 100 is broken, the blade of the extraction mechanism in the future by the extraction mechanism makes it difficult to extract a sufficient lever force.

The extension mechanism 40 of the embodiment of the present invention cuts the attachment A with the lower edge 41b to increase the thickness of the upper side of the inclined face 100a to prevent breakage of the root 100 during extraction, To be able to exercise.

Further, since the discharge hole 41e penetrating the upper surface of the edge block 41 from the discharge groove 41d is formed, bleeding discharge of blood is further facilitated.

The bleeding blood generated by alternately forming the side blade 41a and the discharge groove 41d on the side surface of the edge block 41 can be smoothly discharged through the discharge groove 41d, So that the cutting precision of the surface can be increased.

That is, when the bleeding blood generated at the time of cutting the alveolar bone 30 by the edge block 41 remains between the edge block 41 and the alveolar bone 30, The cutting precision is lowered.

As described above, after the socket 31 is extended by the expansion mechanism 40 of the embodiment of the present invention to form the expansion groove 32 as shown in Fig. 1D, the annular groove 32 as shown in Figs. 1E and 3, An annular groove 33 (see FIG. 1F) is formed in the periphery of the root 100 by the forming mechanism 50 and the end portion of the extraction tool 60 (see FIG. 1C) 61e into the annular groove 33, and the root 100 is extracted by the air suction force.

1E and 3, the annular groove forming mechanism 50 includes a rotation block 51 having an annular toothed blade 51a at a lower end edge thereof and a stopper projection 51b at a central portion thereof, And a rotary drum 52 fixed to the rotary block 51 and connected to a rotary motor (not shown) at an upper end thereof.

1D to 1F, the annular groove forming mechanism 50 as described above enters the extended groove 32 and is rotated to form an annular groove 33 having a depth of about 2 to 3 mm around the root 100, As shown in FIG. 3, the stopper protrusion 51b abuts against the upper surface of the root 100, thereby limiting the depth of the annular groove 33 formed therein.

1G and 4 to 6, the extraction mechanism 60 includes an end 61e formed between the tooth root 100 and the alveolar bone 30 and having a suction hole 61d formed therein, A handle 62 coupled to the other end of the hollow tube 61 to rotate the hollow tube 61 and suction means for providing an air suction force to the suction hole 61d do.

A slip prevention protrusion 62a is formed on the outer peripheral surface of the handle 62 so as to prevent slippage when the dentist grasps and rotates the handle.

The suction means is formed with an expansion hole 62a communicating with the suction hole 61d in the handle 62 and rotatably coupled to the expansion hole 62a and connected to the suction hole 61d, A nozzle body 63 having a nozzle pipe 63a protruding outward from the handle 62 and a coupling plate 64 screwed to the handle 62 to prevent the nozzle body 63 from being separated, And an air pump (not shown) connected to the nozzle pipe 63a.

The end portion 61e is formed in an arc shape having a curvature smaller than the curvature of the root 100, as shown in FIG.

In this case, when the hollow tube 61 is rotated to the left and right, both ends B and C of the end portion 61e are pressed alternately to the outer peripheral surface of the root 100 to minimize damage to the alveolar bone 30, So that it can be separated.

The hollow tube 61 includes a large diameter portion 61a to which the handle 62 is coupled and a small diameter portion 61b in which the diameter of the small diameter portion 61a and the small diameter portion 61b are formed, And is formed as a contracting portion 61c for connecting.

The large diameter portion 61a can resist torsion upon rotation of the handle 62 and the small diameter portion 61b can smoothly enter the narrow space between the alveolar bone 30. [

The small diameter portion 61b is formed in a tapered shape having a smaller width toward the free end, so that the small root 100 can be easily pressed.

The use of the discoid dislocation mechanism 60 of the embodiment of the present invention as described above allows the end portion 61e to be inserted between the root 100 and the alveolar bone 30, Use the two index finger to rotate the knob 62 to the left and right.

At this time, both ends B and C of the end portion 61e press the outer circumferential surface of the root 100 alternately to separate the root 100 from the alveolar bone 30 while minimizing damage to the alveolar bone 30.

Subsequently, the air pump is operated to cause the air suction force to act through the suction holes 61d to cause bleeding blood to be discharged through the suction holes 61d, and the suction holes 61d are brought into close contact with the side portions of the root 100 When the dislocation mechanism 60 is removed after the root 100 is attracted to the end portion 61e by the air suction force, the root 100 is extracted.

7 shows another embodiment of the expansion mechanism 40 according to the present invention. This is because the annular blade 41f annularly protruding from the bottom edge of the edge block 41 is further formed, 31 and the annular groove 33 is formed between the root root 100 and the alveolar bone 31 so that the use of the annular groove forming mechanism 50 can be excluded.
