Description

technical field [0001] The invention relates to a medical device, in particular to an oblique and sliding hand surgical screwdriver operating rod. Background technique [0002] Most of the existing screwdrivers of different types used in hand surgery are equipped with their own operating rods. Although this design is simple in structure, it is easy to damage the screwdriver and is an inseparable whole with the operating rod. The rod can also become scrap due to damage to the screwdriver, which makes the surgical instrument cost prohibitive and wasteful. At the same time, since the medical instruments need to be sterilized before and after the operation, the operating rod 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.

Problems solved by technology

[0002] Most of the existing screwdrivers of different types used in hand surgery are equipped with their own operating rods. Although this design is simple in structure, it is easy to damage the screwdriver and is an inseparable whole with the operating rod. Rods can also be scrapped due to damaged screwdrivers, making surgical instruments cost prohibitive and wasteful

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

[0003] To avoid the above problems, it is necessary to make the screwdriver and its operating rod detachable, but it is necessary to achieve a fast connection, quick disassembly and replacement between the two, and a stable, firm, and non-loose connection between the two. In combination, 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
