Torque wrench used for assembling and disassembling working tips of ultrasonic medical equipment

Abstract

The invention discloses a torque wrench used for assembling and disassembling working tips of ultrasonic medical equipment. The torque wrench comprises a wrench cover and a wrench seat. The upper portion of the wrench seat is arranged in the wrench cover in a sleeved and fixed mode. The lower portion of the wrench seat is of a hollow columnar structure with ends sealed. A wrench position opening is formed in a sealed opening of the wrench seat, and a working tip groove penetrating through the wrench position opening is formed in the circumferential surface and a sealing opening on the lower portion of the wrench seat from outside to inside. The torque wrench further comprises an insert. The insert is fixed to the upper portion of the sealing opening, an insert position opening is formed in the position, corresponding to the wrench position opening, of the insert, a working tip groove penetrating through the insert position opening is also formed in the position, corresponding to the working tip groove, of the insert from outside to inside, a clamping groove penetrating through the insert position opening is further formed in the insert, and a clamping piece is arranged in the clamping groove. The working tip groove can penetrate through the wrench position opening from the lower portion of the wrench seat to be clamped into the torque wrench from the lateral side, and therefore working tips of all shapes can be inserted into the torque wrench and can be assembled or disassembled.

Description

technical field [0001] The invention relates to a tool for a medical device, in particular to a force limiting wrench for loading and unloading the working tip of an ultrasonic medical device. Background technique [0002] Ultrasonic medical equipment includes ultrasonic tooth scaler, ultrasonic bone knife machine, etc., through the contact of the working tip of ultrasonic vibration with the working surface, it can physically remove specific functions such as stains, tartar or bone cutting on the tooth surface. The working tip is installed on the handle of the ultrasonic medical equipment through threads (internal thread or external thread). The rear part of the working tip is usually a cylinder, and a wrench is provided on the cylinder, which is convenient for screwing and installing with tools. In order to be suitable for different functional requirements and also for hygienic requirements, it is often necessary to disassemble the working tip from the handle for replacemen...

AI Technical Summary

Problems solved by technology

When the working tip has more than two bends or the structure of the working tip is relatively special, the working tip cannot be inserted into the inside from the lower clamping opening of the wrench, and there is no way to use the existing wrench for this special working tip. operate
