Backwards-turnable type hand surgery quick-assembling handle

Abstract

The invention relates to a medical appliance, in particular to a backwards-turnable type hand surgery quick-assembling handle. The backwards-turnable type hand surgery quick-assembling handle consists of a base, a positioning groove, an anti-rotation groove, a sleeve, a positioning block, a snap ring, a tail disk, a spring, a handle, a raised strip and a replaceable head, wherein the base is cylindrical; an n-shaped positioning groove is formed on a side wall of the base; the positioning block is a cubic bulge positioned on a side wall of the left end of the handle; the positioning block and the handle are formed into a whole; and the positioning block is positioned in the positioning groove and is movably matched with the positioning groove. Compared with the prior art, the backwards-turnable type hand surgery quick-assembling handle fully avoids stripping between a screw driver or a screw tap and a handle by adopting the n-shaped positioning groove to lock the base of the replaceable head and the handle when used, is stable, and can be conveniently and quickly assembled and disassembled at the same time.

Description

technical field [0001] The invention relates to a medical device, in particular to a twist-back quick-install handle for hand surgery. Background technique [0002] Most of the existing screw taps, countersinks, and screwdrivers screwed into the screws are equipped with their own handles. Although such a design is simple in structure, it is inseparable from the handle because the screw taps and screwdrivers are easily damaged. Therefore, the intact handle will also become a waste product because of the damage of the screw tap and the screwdriver, which makes the cost of the surgical instrument too high and causes waste. At the same time, since the medical instruments need to be sterilized before and after the operation, the handle will occupy a large space after entering the disinfection equipment. On the one hand, the cost of disinfection is increased, and the efficiency of disinfection is also reduced. [0003] To avoid the above-mentioned problems, it is necessary to mak...

AI Technical Summary

Problems solved by technology

[0002] Existing screw taps, countersinks, and screwdrivers screwed into screws in existing hand surgery are mostly equipped with their own handles. Although such a design is simple in structure, it is inseparable from the handle because the screw taps and screwdrivers are easily damaged. Therefore, the intact handle will also become a waste product due to the damage of the screw tap and the screwdriver, which makes the cost of the surgical instrument too high and causes waste

At the same time, since medical instruments need to be disinfected before and after surgery, the handle will occupy a large space after entering the disinfection equipment, which increases the cost of disinfection and reduces the efficiency of disinfection.

[0003] In order to avoid the above problems, it is necessary to make the taps, screwdrivers and their handles separable, but it is necessary to make the two easy to connect quickly, quickly disassemble and replace, and to make the two stable, firm, and free of looseness. This is a problem that those skilled in the art have been eager to solve but have not been able to thoroughly solve for many years
