Abstract

The invention provides a medical torsion tool with the counting and self-destruction functions. The medical torsion tool comprises a torsion body formed by combining a handle cover and a shell. A shell sleeve is arranged on an inner cavity of the torsion body. The lower end of the shell sleeve is detachably connected with a screwdriver bit. The inner cavity of the shell sleeve is provided with a clamping device and a counting and self-destruction device. The counting and self-destruction device comprises a counter, a counter end cover, a counter end cover screw, a connection bolt and a first pressure spring, wherein a washer is arranged in the middle of the connection bolt, and the spring segment between the washer and the counter is in a compression state. When the number of times marked by the counter reaches the preset maximum value, the upper end of the connection bolt is separated from the counter end cover screw, the screwdriver bit does not bear the torsion any more when the torsion body is twisted, and self-destruction is generated in the medical torsion tool. The medical torsion tool can only be used limited times, and medical safety of patients is guaranteed.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a medical torque tool with counting and self-destruction functions. Background technique [0002] At present, known screwdriver is made up of three parts of handle, knife bar and knife head. The medical screwdriver is mainly used for clinical splint fixation. It has been found in clinical practice that screwdrivers of different sizes and types are often required to prepare different sizes and types of implants corresponding to different types of implants from different companies in the patient's body during internal fixation removal. Once the model does not match, you will face the embarrassing situation that you cannot handle the screw and have to wait for the screwdriver of the correct model to be re-sterilized. It not only prolongs the operation time, but also increases the risk of infection and bleeding for patients. [0003] During the clinical treatment process, in mos...
