Orthopedic fixation forceps

Abstract

The invention discloses an orthopedic fixation forceps, comprising a fixation block and an inlay 1 and an inlay 2 symmetrically hinged on one side of the fixation block, and the inlay 1 and the inlay 2 are respectively penetratingly provided with a fixation column 1 and a fixation column. column two. During the operation of the present invention, since the bone surface is arc-shaped, when the two clamping chains approach, the clamping rod of a certain rectangular fixed block of the clamping chain first contacts the bone surface, and slowly approaches along with the clamping chain, so that The clamping rod pushes the sliding plug upwards to move the compression spring and drives the liquid inside the piston chamber 1 to squeeze into the piston chamber 2, so that the sliding plug 2 inside the piston chamber 2 moves to the left to drive the push rod to move, and the push rod moves Push the rectangular body fixed block on its left side, so that the rectangular body fixed block turns over around the rectangular body fixed block on its left side, so that the clamping chain forms a shape that matches the arc shape of the bone for clamping, which improves the clamping efficiency. Poor stability, avoid slipping.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an orthopedic fixation forceps. Background technique [0002] Fractures of the short tubular bones of the hands and feet often affect the functions of the hands and feet due to fracture malunion, joint stiffness, and tendon adhesions. Especially comminuted fractures have very high requirements for reduction and fixation, and non-surgical treatment is difficult to achieve the reduction requirements , in the treatment process, doctors often use fixation forceps to fix the fracture, and then nail the reduction pin. [0003] At present, the general structure of common fixed pliers includes two sets of pliers arms and tapered jaws fixedly arranged at one end of the pliers arms, and the two sets of pliers arms are rotatably connected by pin shafts. During use, the two sets of forceps arms are manually controlled to clamp the two sets of tapered forceps arms on the wounded ...

AI Technical Summary

Problems solved by technology

[0004] However, common fixation forceps still have the following defects and deficiencies in the application process: the contact area between the tapered jaws and the bone surface is small, which makes the contact surface of the jaws not firm enough, and it is not convenient for doctors to use reset pins to accurately locate the wounded part. The tapered jaws are easy to scratch the affected area, increasing the patient's pain
