Universal medical screwdriver auxiliary tool

Abstract

The invention discloses a universal medical screwdriver auxiliary tool which comprises a fixed handle body and a movable handle hinged thereto. The middle section of the fixed handle body is providedwith a first clamping arm, and the front section of the fixed handle body is a front handle, and the rear section of the fixed handle body is a rear handle. The front section of the movable handle isprovided with a second clamping arm, and the front end of the movable handle is hinged to a position between the front handle and the first clamping arm. The first clamping arm and the second clampingarm are each provided with an a radian protruding outwards to form a clamping portion, a locking rod is hinged to the rear handle, the tail end of the movable handle is provided with fixed teeth matched with the locking rod, and an elastic adjusting pressing piece is disposed between the movable handle and a fixed rear handle. The assembly and disassembly of the universal medical screwdriver auxiliary tool are quick, the universal medical screwdriver auxiliary tool can cooperate with screwdrivers of different specifications, the clamping arms are clamped on the two sides of a clamped object,the fixed teeth are clamped in a clamping groove of the locking rod after the positioning, the elastic adjusting pressing piece prevents the handle from being excessively separated and improves tightening force of the locking rod, the clamping is firm, an operator can increase rotating torsion, and the success rate of internal fixation taking out is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically relates to a general-purpose medical screwdriver auxiliary tool. Background technique [0002] With the rapid development of my country's economy and transportation, and the arrival of population aging, traumatic fractures caused by various traffic accidents and falls are becoming more and more frequent. With the continuous updating of treatment concepts, open reduction and internal fixation are the main treatment methods for fractures clinically. At present, most of the internal fixation needs to be removed by secondary surgery. Due to the difference in the time, part and quantity of the internal fixation, the difficulty of removing the plate and screw is also very different, especially for the internal fixation of the lower limbs, the probability of difficult removal is obvious. more than other parts. [0003] At present, there are many manufacturers of inter...

AI Technical Summary

Problems solved by technology

Operators sometimes use vise to clamp, but the vise jaw does not match the straight screwdriver, resulting in unstable clamping and unsmooth operation, which cannot meet actual needs when encountering large resistance

Existing T-shaped screwdrivers usually need to be prepared separately, and during the rotation process, because the T-shaped handle is slender, there is no reasonably designed anti-skid part on the handle, the grip does not match, the rotation force is not enough, and there is a possibility of accidental slippery hands; The T-shaped screwdriver has a longer force arm. In order to meet the needs of a T-shaped handle and a variety of screwdrivers, most of them are combined designs. The combination is not firm, and there is a risk of twisting and deformation when encountering screws with high torsional resistance.
