Accurate-positioning reduction fixing forceps for traumatic orthopedics

Abstract

The invention relates to the field of medical instruments, specifically to an accurate-positioning reduction fixing forceps for traumatic orthopedics. The reduction fixing forceps for the traumatic orthopedics comprises an angle adjusting component and fixing clamp components symmetrically arranged on the left and right of the angle adjusting component. The angle adjusting component comprises an adjuster, a moving part in clearance fit in the adjuster, connecting parts rotationally connected to the left side and the right side of the moving part through rotating shafts correspondingly, and anadjusting screw in threaded fit with the moving part. The ends, away from the moving part, of the connecting parts are rotationally connected with the adjustor through rotating shafts. The rear end ofthe adjusting screw is rotationally connected with the inner wall of the rear side of the adjustor. The front end of the adjusting screw penetrates through the moving part in a threaded mode and penetrates out of the adjustor. The fixing clamp component comprises a first handle-bar and a second handle-bar which are rotatably connected to each other in a crossed manner. By rotating the adjusting screw rod, the angle between the two sets of fixing forceps components is adjusted according to the curvature of a bone part needing to be fixed, then the applicability of the device is improved, the fixing forceps components are convenient to use, and meanwhile the fixing forceps components can be conveniently taken down from the bone part of a patient.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a positioning and accurate reduction and fixation forceps for trauma orthopedics. Background technique [0002] Short tubular bones in the hand often have fracture malunions, joint stiffness, and tendon adhesions that affect the function of the hand, especially for comminuted fractures, which have very high requirements for reduction and fixation, and non-surgical treatment is difficult to achieve the reduction requirements. Doctors often use fixation forceps to fix the fracture, and then nail the reduction pin. [0003] At present, the Chinese patent No. "201921002648.7" discloses an accurately positioned reset fixation forceps for traumatic orthopedics, including the main lower forceps body and the auxiliary lower forceps body. The opening can pass through the clamping horizontal bar. After moving the auxiliary lower pliers to a suitable distance from the main lower pliers, ...
