Abstract

The utility model relates to a condyle process resetting clamp which comprises two clamp handles in crossed pivoted connection. The front ends of the clamp handles are clamp edge parts, while the rear ends are holding parts. The clamp edge parts consist of upper clamp edges and lower clamp edges matched with the upper clamp edges. The upper and lower clamp edges are provided with front and rear prongs arranged at intervals. The rear prongs are less than the front prongs in length. According to the condyle process resetting clamp, the rear prongs are less than the front prongs in length, so that the upper clamp edges and lower clamp edges clamping the fracture block of the condyle process are stable to clamp, and displacement of the fracture block of the condyle process is difficulty to occur. Due to morphologic characteristics of the condyle process, a clamping area which is higher inside and lower outside on the condyle process bone face exists and the front and rear prongs which are short inside and long outside exist, so that the front and rear prongs are easy to stress in position at the same time in allusion to the morphologic characteristics of the condyle process.

Description

The condyle reduction forceps of dashing forward

Technical field

This utility model relates to medical apparatus and instruments, specifically refers to the prominent reduction forceps of the convenient condyle that uses.

Background technology

Condyle fracture of mandibles is modal maxillofacial fracture.It is rear because being attached to the muscle contraction at condylar fracture piece position that fracture occurs in condyle of mandible, make mandibular ramus broken ends of fractured bone upward displacement, and the interior side's displacement forward of condylar fracture piece, cause patient's occlusal disturbance, if untimely row reduction of the fracture fixing operation, easily cause the sequela such as meshing functions obstacle, ankylosis and jaw facial deformity, very harmful to patient.the open reduction Rigid internal fixation is the main method for the treatment of condyle fracture of mandibles at present, its process needs surgical incision to expose the remporomandibular joint district, seek and appear condyle fracture of mandibles, with the lower anatomical reduction of the capable direct-view of condylar fracture piece, then fix with lag screw or little titanium plate, Operative Puzzle is the searching of condylar fracture piece and resets, because the joint space appears often more difficult, the condylar fracture piece is tiny and mainly take spongy bone as main, be not easy to grip, usually because the reduction instrument improper use causes the condylar fracture piece cracked, surgical outcome is caused disastrous effect.

With reference to accompanying drawing 3 and Fig. 4.it is at present clinical that to be specifically designed to the reduction forceps that condylar fracture resets more rare, the prominent reduction forceps of condyle that only has German medicon company to produce, the prominent reduction forceps of this condyle comprises two clamp handles 1 that the intersection hinge connects, 2, these two clamp handles 1, 2 front end is pincers beak section, its rear end is the grip part, this pincers beak section is made of upper pincers beak 10 and the lower pincers beak 20 that coordinates with upper pincers beak 10, on being somebody's turn to do,

lower pincers beak

10, 20 be equipped with spaced apart before,

rear tooth point

30, 31, before being somebody's turn to do, the length of crown 30 and rear tooth point 31 is equal in length, described grip part is made of upper grip part 11 and the lower grip part 21 that coordinates with upper grip part 11, upward the inboard of grip part 11 is provided with a shangguan pole 110, the inboard of described lower grip part 21 is provided with ShiShimonoseki pole 210 that coordinates with shangguan pole 110, the length of this shangguan pole 110 is greater than the length of ShiShimonoseki pole 210.

With reference to accompanying drawing 3, Fig. 4, Fig. 5 and Fig. 6.The prominent reduction forceps of above-mentioned condyle in actual use, some inconvenient parts can appear, the design equal in length of the length of front crown 30 and rear tooth point 31, due to the Morphological Features of condyle prominent 4 own, condylar fracture piece 40 often is rendered as inner small and outside big form, when the upper pincers beak 10 of the prominent reduction forceps of this condyle and 20 pairs of condylar fracture pieces of lower pincers beak 40 carried out clamping, front crown 30 and rear tooth point 31 were difficult for clamping simultaneously and put in place, are prone to the phenomenon that makes 40 displacements of condylar fracture piece because clamping is unstable; The length of shangguan pole 110 is greater than the design of the length of ShiShimonoseki pole 210, when upper pincers beak 10 and 20 pairs of condylar fracture pieces of lower pincers beak 40 carry out clamping, the end of shangguan pole 110 can be projected into the outside of lower grip part 11, and the hand of easily conflicting brings inconvenience to operation.

The utility model content

This utility model provides the condyle reduction forceps of dashing forward, and the structural design that its main purpose is to overcome the prominent reduction forceps of existing condyle is unreasonable, to easily the conflict shortcoming of hand of the end of the unstable phenomenon that easily makes the displacement of condylar fracture piece of the prominent clamping of condyle and shangguan pole.

For solving the problems of the technologies described above, this utility model adopts following technical scheme:

The condyle reduction forceps of dashing forward, comprise two clamp handles that the intersection hinge connects, the front end of these two clamp handles is pincers beak section, its rear end is the grip part, this pincers beak section is made of upper pincers beak and the lower pincers beak that coordinates with upper pincers beak, this upper and lower pincers beak is equipped with spaced apart forward and backward crown, and the length of described rear tooth point is greater than front crown length.

Further, described grip part is made of upper grip part and the lower grip part that coordinates with upper grip part, and on this, ShiShimonoseki pole of the length of the shangguan pole of inboard, grip part and inboard, lower grip part is equal in length.

Further, the equal indentation of leading portion medial surface of described upper and lower pincers beak.

By above-mentioned description to this utility model structure as can be known, compared to the prior art, the utlity model has following advantage:

One, in the prominent reduction forceps of this condyle, the length of rear tooth point is less than the design of the length of front crown, and when making pincers beak and lower pincers beak advance by leaps and bounds capable clamping to condyle, clamping is stable, is difficult for making the displacement of condylar fracture piece.Due to the prominent Morphological Features of condyle itself, there is low inside and high outside clamping zone in the prominent surface of bone of condyle, and forward and backward crown is the outer short design of interior length, and for the prominent Morphological Features of condyle itself, forward and backward crown is stressed putting in place simultaneously easily.

Its two, the design equal in length of ShiShimonoseki pole of the length of the shangguan pole of inboard, upper grip part and inboard, lower grip part, the end of upper and lower articulated arm is not prone to and is projected into the outside of grip part accordingly, the hand of more can not conflicting, convenient operation.
