A medical torque tool with counting and self-destruction functions

Abstract

The invention provides a medical torsion tool with counting and self-destruction functions, which comprises a torsion body composed of a handle cover and a casing. The inner cavity of the torsion body is provided with a casing sleeve, and a screw is detachably connected to the lower end of the casing sleeve. The batch head is provided with a clamping device and a counting self-destructing device in the inner cavity of the shell sleeve. The counting self-destructing device includes a counter, a counter end cover, a counter end cover screw, a connecting bolt and a first pressure spring. There is a meson, and the spring section between the meson and the counter is compressed. When the number of times marked by the counter reaches the preset maximum value, the upper end of the connecting bolt will be detached from the screw of the counter end cover, so that the screwdriver head will no longer be subjected to torque when the torque main body is twisted, and the medical torque tool will self-destruct inside; The invention realizes that the medical torque tool can only be used for a limited number of times, ensuring the medical safety of patients.

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...

AI Technical Summary

Problems solved by technology

[0003] During clinical treatment, in most cases, the same medical torsion tool will be used for splint fixation. The medical torsion tool in the prior art cannot be used for one-time use, let alone one-time self-destructive use; if the disinfection work is not done If it is in place, it is easy to form cross-infection, which is not conducive to the medical protection of patients
