Abstract

The utility model relates to an orthodontic rectangular wire torque forceps comprising a forceps handle and a forceps beak, and is characterized in that: the forceps beak consists of mutually engaged convex keeper and concave keeper. The convex keeper is provided with a latch, end surface of the latch is an inclined plane, with a bevel angle of 5 DEG to 15 DEG, the concave keeper is provided with a slot with a width of 0.5 to 1.0mm, bottom of the slot is crossly divided from the center, and two opposite inclined planes with the same angle are formed on both sides. The utility model can conveniently carry out torque of the rectangular wire in rectangular arch wire correction technology(including torque compensation in straight arch wire technology, sliding straight arch wire technology). The utility model has the advantages that: 1. the rectangular wire torque operation merely requires a forceps, thus simplifying clinic operation and saving time; 2. after torque operation, shape of arch wire is not destroyed, thus reducing time for clinic operation and maintaining accuracy of the arch wire; 3. torque angle is accurate and can be quantified.

Description

Mouth cavity orthodontic side's silk torque pincers

Technical field

This utility model relates to a kind of cutting pliers, specifically a kind of mouth cavity orthodontic side silk torque pincers.

Background technology

Side's silk begg appliance technology is the mainstream technology of present oral cavity Fixed Orthodontics, and side's silk bow torque is the characteristics and the difficult point of this technology.Side's silk begg appliance technology has three sequence bendings, and first order bend is a horizontal bend, and to bending, third order bend is the torque bending to second order bend, i.e. the axial torsion of arch wire for vertically.The common way of arch wire torque is to utilize two flat-nose pliers (title side's silk torque pincers again), clamps the both sides of desiring torque place arch wire, utilizes the opposite spin of both hands, finishes the torque of edgewise wire bow.Because the two handss unstability of exerting oneself, finish silk bow after the torque often not on same plane, and need adjust arch wire once more, when adjusting arch wire, the original arc attitude of silk is changed, thereby bring many difficulties to clinical manipulation.Therefore inventing a kind of mouth cavity orthodontic side silk torque pincers is highly profitable.

Summary of the invention

Goal of the invention of the present utility model is exactly in order to solve the defective that existing product exists, to provide a kind of mouth cavity orthodontic side silk torque pincers, to remedy the deficiency of existing product.

The technical solution of the utility model is achieved in that it comprises pincers handle and pincers beak, it is characterized in that: the pincers beak is made up of intermeshing convex armature and spill armature, convex armature is provided with latch, and the end face of latch is the inclined-plane, and its inclination angle is 5-15 °, spill armature is provided with groove, the wide 0.5-1.0 millimeter of groove, cross-section separately from center line at the bottom of the groove, it is identical respectively to form the number of degrees to both sides, the inclined-plane that direction is opposite, and the inclined-plane wedging mutually of latch on this inclined-plane and the convex armature.

Described convex armature is provided with six latches, and spill armature is provided with corresponding six groove a, b, c, d, e and f; First latch on the described convex armature is identical with the profile of tooth of the 4th latch, the inclination angle of its end face is 5 °, second latch is identical with the profile of tooth of the 5th latch, the inclination angle of its end face is 10 °, the 3rd latch is identical with the profile of tooth of the 6th latch, and the inclination angle of its end face is 15 °; Wide identical with a, b in the corresponding spill armature of described convex armature, three grooves of c, its groove is wide to be 0.7 millimeter, d, e, three grooves of f wide identical, its groove is wide to be 1.0 millimeters.

Side's silk torque pincers of the present utility model are to utilize the groove of jaw upper armature and the wedging action of projection, (groove is different torque angle with convex design), and disposable clamp can be finished the torque of corresponding site square arch wire.Because the design of torque groove is at same horizontal plane, after finishing torque, the silk bow can the outer deformation of amount.

This utility model can carry out torque by square shaped silk bow easily in side's silk begg appliance technology (containing the compensating torque in raw silk rings bow technology, the sliding mechanic straight wire technology).It has the following advantages:

1. side's silk torque operation only needs to use a pair of tongs to finish, and has simplified clinical manipulation, has saved the time

2. the shape of torque operation back silk bow is not destroyed, and has reduced the clinical manipulation time, has kept the precision of silk bow.

3. torque angle is accurate, can quantize.

The specific embodiment

As shown in Figure 1 and Figure 2, this utility model comprises pincers handle 1 and pincers beak 2, and pincers beak 2 is made up of intermeshing convex armature 3 and spill armature 4, and convex armature 3 is provided with latch 5, the end face of latch 5 is the inclined-plane, its inclination angle is 5-15 °, and spill armature is provided with groove, the wide 0.5-1.0 millimeter of groove, shown in the hatching line among Fig. 3 groove a, cross-section separately from center line at the bottom of the groove, it is identical respectively to form the number of degrees to both sides, the inclined-plane that direction is opposite.

Preferably be provided with six latches on the described convex armature, spill armature is provided with six groove a, b, c, d, e and f to correspondence; First latch on the described convex armature is identical with the profile of tooth of the 4th latch, the inclination angle of its end face is 5 °, second latch is identical with the profile of tooth of the 5th latch, the inclination angle of its end face is 10 °, the 3rd latch is identical with the profile of tooth of the 6th latch, and the inclination angle of its end face is 15 °; Wide identical with a, b in the corresponding spill armature of described convex armature, three grooves of c, its groove is wide to be 0.7 millimeter, d, e, three grooves of f wide identical, its groove is wide to be 1.0 millimeters.
