Abstract

The present invention combines two instruments that dentists use to treat orthodontic patients: cutter [figure 5] and tucker [figure 6]. Until now, the medical treatment operation has to be repeatedly used to exchange the two instruments in succession, so there is a problem that the medical treatment is cumbersome by repeating the operation of changing the apparatus from the cutter to the tucker and the tucker to the cutter. The present invention is a part for performing the function of the tucker (81,82,83,84,85,86,810) to one handle (61,62,63,64,65,66,610) of the existing cutter for the purpose of solving this. However, the tucker of this region has a feature that can be rotated independently of the cutter and the user can be separated and assembled from the cutter arbitrarily. Tucker and cutter coupling method that meets the above characteristics are used in various forms of screw assembly, the principle of the latch, and the magnetic rod. This makes the dentist's medical treatment more comfortable and simpler, enabling smooth flow of medical treatment, increasing the efficiency of medical treatment and reducing the medical treatment time, and rotating the tucker (81.82,83,84,85,86,810). It is possible to perform accurate tucking (tucking) operation at any position of the tooth and can be used by selectively assembling various types of tucker according to the user's taste.

Description

Dental orthodontic cutters {Pin & ligature cutter}

The present invention combines two of the tools that dentists use to treat orthodontists, allowing them to perform two functions in succession as a single instrument.

One of the primary treatments of dentists treating orthodontists is the use of an arch wire into the slot 1 of the bracket [FIG. 1] attached to the patient's teeth. After tightly inserting 3), the ligature wire 4 is hung on the wing 2 of the bracket so that the inserted straightening line 3 does not escape from the insertion groove 1, and then ligation is performed. By holding both ends of the line with the ligation forceps (5) to continue twisting in one direction [Fig. 2], it is to perform a stable and close ligation (ligation or tying). And, the long twisted ligation line portion is cut short [Fig. 3], the instrument used at this time is a pin and ligature cutter (ligature cutting plier, hereinafter cutter) [Fig. 5].

At this time, the shape of the conventional cutter handle is a half-moon-shaped cross-section [Fig. 5 (b)]. However, since the cut ligament site is very sharp, it may pierce the lips of the orthodontic patient, so it should be bent immediately so that the cut edge does not point toward the lips. The instrument used is a tucker (ligature tucker or ligature director) [Fig. 6]. In other words, by moving the tucker to securely push the cut end of the ligation line below the correction line [Figure 4]. If you try to repeat these treatments, namely cutting and tucking per tooth, the repeated use of cutters [figure 5] and tucker [figure 6] is frequently used and treatment efficiency is reduced and treatment time is reduced. There was a problem that this was unnecessarily extended.

The object of the present invention is to provide a function of a tucker [Fig. 6] to one side of the handle of the cutter [Fig. And it is to be able to perform two treatment operations as a single instrument without the need for repeated instrument change operation from the tucker to the cutter. If so, it is necessary to consider what form the tucker attached to one handle of the cutter should be combined in order to perform its original function most efficiently. First, the dentist's tucking operation using the tucker does not simply apply a pushing force by touching the tucker tip to the cut ligament tip, and simultaneously pushes the tucker with the thumb and index finger. Rotating it will bend the cut end of the ligation line exactly to the desired position. Second, the shape of the tip of the tucker is very diverse according to the dentist's preference, so instead of the tucker [Fig. 6 (a) (b)], the band seater [Fig. 6 (c)] or scaler Some dentists prefer to tuck using [Fig. 6 (D)], so the combination of the tucker and the cutter should be able to selectively accommodate various types of tucker, bandsitter or scaler. Third, the tucker can be used semi-permanently, but the cutter should not be able to perform the cutting function when the edge of the blade becomes dull, so it must be replaced with a new one. .

Therefore, the present invention allows the tucker to rotate independently of the cutter and to separate and assemble the tucker from the cutter.

According to the present invention, five embodiments satisfying the above characteristics are possible.

7, 8, 9, and 10 are for the first embodiment of the present invention. First, the cutter handle to be attached to the tucker is shortened and a cylindrical connection 7 having both ends open to the excitation 61 is formed. The tucker 81 is provided with a cylindrical protrusion 9 which can be inserted therein, and forms the female screw 10 at the end portion. The cylindrical protrusion 9 of the tucker 81 is inserted into the cylindrical connecting portion 7 of the cutter handle 61, and then a separate male screw 11 is assembled to the female screw 10. At this time, the diameter of the head portion of the male screw 11 is larger than the diameter of the cylindrical protrusion 9 or the inner diameter of the cylindrical connecting portion 7 so that the tucker 81 and the cutter handle 61 are assembled separately without being separated. . Here, the contact surface between the cylindrical projection 9 and the cylindrical connecting portion 7, the contact surface between the male screw 11 head portion and the cutter handle 61 allows a slight loosening so that the tucker 81 can perform a smooth rotational motion. Make sure

11, 12, 13, and 14 relate to a second embodiment of the present invention. First, the shape of the cutter handle to be attached to the tucker transfers the shape of the cross section from the half moon shape to the circular shape, and the length thereof is shorter than the length of the opposite handle, and then the external thread 12 is formed on the outside, and subsequently the smaller cylindrical shape The projection 13 is given. And the tucker 82 forms a cylindrical recess 14 into which the cylindrical protrusion 13 can be inserted. At this time, the thickness of the tucker 82 should be able to pass through the inner diameter 17 of the female screw portion of the connecting ring 16 in the inlet portion 15 of the cylindrical recess 14, the thickness of the remaining portion is smaller than the connecting ring Allows the passage of a small inner diameter (18) formed at the other end of (16). The connecting ring 16 is firmly fixed so as not to be moved by screw assembly with the male screw 12 on the cutter handle 62 after penetrating through the tucker 82. However, the surface where the tucker 82 is in contact with the cylindrical projection 13 and the connecting ring 16 allows a slight loosening to allow smooth rotation of the tucker 82. The coupling of the coupling ring 16 and the cutter handle 62 forms a hole through the coupling ring 16 and the cutter handle 62 at the same time instead of the screw assembly described above, and then the wires are inserted into the hole so that both ends thereof are joined together. It is also possible by tying.

15, 16, 17, and 18 are for the third embodiment of the present invention. The shape of the cross section is changed from a half moon shape to a circular shape, and a cylindrical protrusion 19 having a thickness slightly smaller than the cutter handle 63 is formed at the end of the cutter handle 63 whose length is shorter than that of the opposite handle. The end portion of the female screw (20) forms. Now inserting the intermediate connecting ring 21 having an inner diameter that can be fitted to the cylindrical projection 19, and then a separate male screw 23 is assembled to the female screw 20. At this time, the head of the male screw 23 is slightly larger than the cylindrical projection 19 is formed with the female screw 20 so that the intermediate connecting ring 21 can be integrated without being separated from the cutter handle (63). However, the surface where the intermediate connecting ring 21 is in contact with the cylindrical projection 19 and the male screw 23 head portion of the cutter handle is loosened slightly to allow the rotation of the intermediate connecting ring 21. Since the female screw 22 is formed at the other end portion of the intermediate connecting ring 21, the male screw 24 is formed on the tucker 83 to be firmly assembled thereto. In this case, since the intermediate connecting ring 21 is already rotatable, the tucker 83 is rotatable integrally with the intermediate connecting ring 21.

19, 20, 21, and 22 are for the fourth embodiment of the present invention. This uses the principle of latch. First, a cylindrical recess 25 is formed on the cutter handle 64, which is shortly cut and the cross-sectional shape is changed from a half moon shape to a circular shape, and the cutter handle 64 is outside the cutter handle 64 via the cylindrical recess 25. Two small holes 26 penetrating 64 are formed. The tucker 84 forms a cylindrical protrusion 27 that can be inserted into the cylindrical recess 25 of the cutter handle 64, but a small hole 26 of the cutter handle 64 penetrates through the cylindrical protrusion 27. The latch groove 28 having a uniform depth is formed around the losing area. Now, the wire 29 is inserted into the two small holes 26 formed in the cutter handle 64 so that the tucker 84 is not separated from the cutter handle 64 during the treatment operation. When the two ends are tied together, the tucker 84 is not separated from the cutter handle 64 by the wire 29 passing through the clasp groove 28, and at the same time, rotational movement is possible. When the tucker 84 is replaced, the bundled wire 29 is removed.

23, 24 and 25 are for the fifth embodiment of the present invention. This is using the magnet's pulling force. First, the cylindrical cylindrical rod 30 of magnet is fixed to the end of the cutter handle 65 which is cut short and the shape of the cross section is changed from the half moon shape to the circular shape. The tucker 85 forms a cylindrical recess 31 into which the cylindrical magnet rod 30 can be inserted. Coupling of the cutter handle 65 and the tucker 85 is maintained by the force of magnet attraction. In the same principle, the tucker and the cutter are fixed by fixing the magnet ring 300 to the tucker 85 so that it acts as a female part for receiving the cylindrical male part formed in the cutter handle 65. Can also be combined.

26, 27, 28, and 29 relates to another embodiment falling within the scope of the first embodiment of the present invention, and relates to the assembly using a wire instead of screw assembly. First, the shape of the cutter handle 66 is the same as in the first embodiment, but the cylindrical projection 96 of the tucker 86 is longer than the length of the cylindrical connection 76 of the cutter handle 66 and penetrates the center at the end portion. To form a small hole (32). Now, the cylindrical protrusion 96 is inserted into the cylindrical connecting portion 76, and then the wire 33 is inserted into the small hole 32 formed at the position just passed through the cylindrical connecting portion 76 to tie the both ends together. By assembling them together.

30, 31, 32, and 33 relate to an embodiment in which the principle of the fourth embodiment of the present invention is applied to the principle of the first embodiment.

First, two small holes 260 are formed in the cylindrical connection portion 70 of the cutter handle 610, and the small holes 260 penetrate the cylindrical protrusions 270 of the tucker 810. The shackle groove 280 is formed around the place corresponding to the losing site. Now, after inserting the cylindrical projection 270 into the cylindrical connection 70, the wire 290 is inserted into the small hole 260 to tie both ends together so that the wires are spread over the clasp grooves, so that they are integrally assembled. Lose.

Instead of the small hole 260 and the wire 290, a small female thread hole and a male thread may be used.

As described above, according to the present invention, since the function of the tucker is provided to the cutter, the procedure of exchanging the tool between the cutter and the tucker is not necessary, so that two medical treatments can be performed as a single instrument, so that the dentist can feel more comfortable and hassle-free. You can take action and your treatment time is shortened. In addition, because the tucker (81, 82, 83, 84, 85, 86, 810) can be rotated, accurate tucking operation can be performed on any tooth, and the tucker can be separated and assembled to the user's taste. Depending on the type of tucker can be selectively assembled, and when the blade edge of the cutter is blunt can be used to assemble the existing tucker to the new cutter.
