Mandibular angle fracture reduction forceps

Abstract

The invention relates to mandibular angle fracture reduction forceps, including a first forcep body and a second forcep body. The two forcep bodies are hinged together through a pin roll. Each forcepbody comprises a forcep claw section on the front part and a handle section on the rear part. The front end of the forcep claw section is provided with a forcep mouth which is used to insert into a corresponding auxiliary retention hole by the side of a fracture line to apply a fold reset force. Each forcep claw section is provided with a support top surface which is used to abut against the surface of a mandibular angle bone on the corresponding side of the fracture line to ensure fracture broken ends on two side of the fracture line to be aligned when the forcep mouth applies fold reset force. The support top surface is arranged on the rear part of the front end of the corresponding forcep claw section in a staggered manner. After the forcep mouth is inserted into the auxiliary retentionhole, through the support top surface on the rear abutting against the mandibular angle bone on the two sides of the fracture line, even though no operation field exists when the reduction forceps apply reset force, the mandibular angle bone on two sides of the fracture line can be ensured to be aligned. The reduction forceps can prevent bones from being damaged since the forcep mouth is insertedtoo deep in the auxiliary retention hole.

Description

technical field [0001] The invention relates to a mandibular angle fracture reduction forceps. Background technique [0002] When the mandibular angle is fractured, the extraoral approach or the intraoral approach is used for reduction surgery according to the fracture situation. Extraoral approach reduction surgery requires an incision in the maxillofacial skin at the fracture site. Usually, the assistant fixes the broken end with both hands. At this time, a bone-synthetic titanium plate can be implanted for post-operative fixation. After the operation, the skin remains longer. Scars affect the appearance; the difference between the intraoral approach and the extraoral approach is that the above operations are completed inside the oral cavity, so the intraoral approach can avoid incisions on the face and scars left on the face, but due to the narrow field of view in the mouth, the reduction effect is difficult. Guaranteed, the broken end of the fracture is prone to shift d...

Problems solved by technology

[0005] The purpose of the present invention is to provide a mandibular angle fracture reduction forceps to solve the technical problem that in the prior art, when the internal fixation forceps apply the reset force, the doctor's operation requirements are high and dislocation is easy to occur, and it is difficult to ensure the alignment of the mandibular angles on both sides of the fracture line.
