Description

[0001] The present invention relates to a dislocation device for a root,

The present invention relates to a dislocation mechanism for a root, and in particular, unlike an extraction mechanism using a whole of a conventional hand, it is possible to dislocate a root with only a small force of two fingers, thereby utilizing a sophisticated sense of a fingertip, It is possible to improve the visual field in a narrow and dark socket by sucking hemorrhagic blood and at the same time attaching to the suction hole of the working blade to exert a suction force so that the dislocated small root is not lost, .

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 extraction forcep or elevator or both at the same time, even if it is a single root that extends from a single crown, If you start with a single root and proceed to the root apex and split into two, it tends to be broken during dislocation.

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.

In addition, approaching a small root, which can be dislocated by the force of a finger, in the form of a grip is sometimes inaccessible due to the lack of income or the form of a large apparatus.

In addition, small fracture root dislocations in the socket often fail to be secured in clinical practice, which can be thrown out during the dislocation or sucked into the suction.

The problem is that the surgeon often fails to perceive the surgeon, which can lead to excessive damage to the surrounding tissue by continuing unnecessary dislocation.

Therefore, there is a need for a dislocation mechanism capable of securely securing the fracture pieces without being lost.

Further, the hollow tube of the dislocation mechanism of the present invention is formed of a large diameter portion to which the handle is engaged, a small diameter portion in which the end portion is formed, and a reduction portion that connects the large diameter portion and the small diameter portion.

Further, the dislocation mechanism of the present invention is characterized in that a slip prevention projection is formed on the outer peripheral surface of the handle.

The dislocation mechanism 60 according to the present invention can dislocate the root using only a small force of two fingers unlike an extraction mechanism using the entire grasping hand so as to utilize the elaborate sense of the fingertip, Thereby improving the field of view in a narrow and dark socket and exhibiting a suction force so that the dislocated small root can not be lost so that it can be attached to the suction hole 61d of the working blade to be safely recovered.

The end portion 61e of the hollow tube 61 is formed in an arc shape so as to have a curvature smaller than the curvature of the root 100 so that when both ends of the end portion 61e B) C alternately pressurize the outer circumferential surface of the root 100 and can be easily separated from the alveolar bone 30.

6 is a cross-sectional view showing an end portion of the dislocation mechanism of the embodiment of the present invention.

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 dislocation mechanism for the root can reduce the damage of the alveolar bone at the same time as the extraction of the hemorrhagic blood, and at the same time, the tooth root can be pulled out even with a small force of two fingers.

The dislocation mechanism 60 for the root according to the embodiment of the present invention for extracting the root rods 100 remaining in the alveolar bone 30 is provided with the roots 100 and the alveolar bone 30, And a handle 62 coupled to the other end of the hollow tube 61 to rotate the hollow tube 61. The hollow tube 61 has an end 61e formed at one end thereof with a suction hole 61d, And suction means for providing an air suction force to the suction holes 61d.

A slip prevention protrusion 62b is formed on the outer circumferential surface of the handle 62 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.
When the user holds the handle 62 and reciprocally rotates left and right, the hollow tube 61 is also reciprocally rotated right and left to separate the root 100 from the alveolar bone 30.
The nozzle body 63 is rotatably coupled to the expansion hole 62a so that the nozzle body 63 and the nozzle tube 63a are rotated by the handle 62 when the user rotates the knob 62 leftward and rightward. It is possible to maintain the same position without rotating together.
Accordingly, the nozzle tube 63a does not flow despite the left-right rotation of the knob 62, so that the user's hand or arm and the nozzle tube 63a interfere with each other when the user performs the operation of extracting the root- So that the extraction work can be concentrated.

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.

The dislocation mechanism 60 as described above separates the root 100 from the alveolar bone 30 by rotation of the end portion 61e between the root 100 and the alveolar bone 30, So that the dentist can easily perform the extraction work and the root roots 100 are guided by the air suction to the distal end of the dislocation mechanism 61e so as to be able to exclude the use of a mechanism such as a conventional forceps.

In order to allow the end portion 61e of the dislocation mechanism 60 to smoothly enter between the root 100 and the alveolar bone 30 in the embodiment of the present invention, An expanding mechanism 40 for expanding the socket 31 of the alveolar bone 30 as shown in Figs. 1C and 2 and an annular groove forming mechanism 50 as shown in Figs. 1E and 3 are used.

The expansion mechanism 40 includes a truncated conical edge block 41 having a side edge 41a formed on a side surface portion and a lower surface edge 41b formed on a lower surface thereof, And a rotation rod 42 to which a rotation motor (not shown) is connected to the other end.

A planar portion 41c on which the lower edge 41b is not formed is formed at the center of the lower surface of the edge block 41 so that the planar portion 41c contacts the upper surface of the root 100, .

1B and 1C, the expansion mechanism 40 may be configured such that the edge block 41 is rotated by a rotation motor (not shown) to the socket 31 extracted with the root rods 100 remaining, So that the surface of the alveolar bone 30 is cut and expanded.

At this time, the lower surface of the edge block 41 reaches the upper surface of the root 100. Since the surface of the edge block 41 contacts the upper surface of the root 100, cutting is not performed. Entry will be stopped.

The bleeding blood generated at this time is smoothly discharged through the discharge groove 41d and the discharge hole 41e penetrating the upper surface of the edge block 41 from the discharge groove 41d is formed, To make it better.

That is, the edge block 41 is lowered in the depth direction of the tooth groove 31, the surface of the alveolar bone 30 is cut to expand the tooth groove 31, and the flat surface portion 41c is formed on the upper surface of the root 100 So that the dentist who is not experienced can stably use the expanding mechanism 40. Further,

Here, it is preferable that the diameter of the bottom surface of the edge block 41 is larger than the diameter A of the fracture surface of the extracted tooth 110 (see FIG. 1A) by about 1 mm.

1D, the annular groove forming mechanism 50 enters the enlarged groove 32 extended by the enlarging mechanism 40 to form an annular groove 33 in the periphery of the root 100 .

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 is inserted into the extended groove 32 and rotated to form an annular groove 33 having a depth of 2 to 3 mm in the periphery of the root 100 As shown in FIG. 3, the depth of the annular groove 33 is defined by the stopper projection 51b contacting the upper surface of the root 100.

By disposing the socket 31 by the expansion mechanism 40 and forming the annular groove 33 around the root 100 by the annular groove forming mechanism 50 as described above, the dislocation mechanism 60 of the embodiment of the present invention So that the end portion 61e of the root canal 61 can easily enter between the root root 100 and the alveolar bone 30.
