Reconstruction plate bending pliers

Abstract

The invention discloses reconstruction plate bending pliers which comprise a left pliers leg and a right pliers leg, the reconstruction plate bending pliers further comprise a left roller, a right roller, a left roller shaft, a right roller shaft, a locating sleeve and a locating plate, wherein a locating shaft and a locating block are arranged on the locating plate, a left roller hole and a center locating hole are formed in the left pliers leg, a right roller hole and a center locating hole are formed in the right pliers leg, the left roller shaft and the right roller shaft are sleeved with the left roller and the right roller and connected with the left roller hole and the right roller hole, the locating block is located in the middle position of the left roller hole and the right roller hole, the locating shaft penetrates through the center locating holes of the left pliers leg and the right pliers leg and is connected with the locating sleeve, the locating sleeve comprises a top corner and a base part, and the top corner is at a fixed angle and located under the locating block. According to the reconstruction plate bending pliers, a reconstruction plate is completed in a rolling manner by the aid of the rollers at the top ends of the pliers lags, so that the angle of a formed titanium plate is smoother, mechanical damage to the titanium plate in the bending process is reduced, and the top corner of the locating sleeve is at the fixed angle so that the titanium plate can obtain the required angle by one time.

Description

technical field [0001] The invention belongs to medical instruments, and more specifically relates to a bending forceps for bending mandibular bone reconstruction transplantation bone fixation titanium plate in oral and maxillofacial reconstruction surgery. Background technique [0002] During mandibular reconstruction, the mandibular fibular reconstruction plate needs to be bent. Several existing instruments for bending mandibular and fibular reconstruction plates have their own limitations. [0003] KLS Martin multi-function bending clamp (50-502-10-07): The bending clamp has multiple functions such as 3D bending, 90° bending, titanium plate cutting, etc., but the operation of the bending clamp is cumbersome and complicated.

Problems solved by technology

[0003] KLS Martin multi-function bending clamp (50-502-10-07): The bending clamp has multiple functions such as 3D bending, 90° bending, titanium plate cutting, etc., but the operation of the bending clamp is cumbersome and complicated. The requirements for clinical operation experience are relatively high, which is not conducive to beginners to master

[0004] Synthes reconstruction plate bending pliers (329.143): The bending plate pliers completes the shaping of the reconstruction plate through in-plane bending, out-of-plane bending and coracoid bending. This method is the most widely used in clinical practice. method, which is complicated to operate and is not conducive to quickly completing the shaping of the reconstructed titanium plate

In addition, repeated bending of the rebuilding plate can greatly reduce the service life of the rebuilding plate

[0005] In addition, the mandibular reconstruction plate bent by the above-mentioned equipment cannot fit closely with the transplanted fibula, and there may be a risk of displacement of the grafted bone block or deformation of the titanium plate after titanium nail fixation
