Description

Technical Field

[0001] This utility model belongs to the technical field of circumcision device supporting structure design, and in particular relates to an operating handle for a circumcision device. Background Technology

[0002] A circumcision ligator is a specialized medical device used for circumcision surgery. It mainly consists of the ligator body and an operating device used to control the power output in conjunction with the ligator body. Common types include gun-type and cylindrical types. The gun-type type is larger, more complex, and more expensive to use. The cylindrical type is smaller and easier to use, but it generates more noise and vibration during use. Its internal reciprocating motion structure requires rapid movement and high impact force. However, due to structural design and material limitations, the moving parts may directly strike the surgeon's wrist or impact the shell structure during the ligation surgery, which can adversely affect the ligation procedure.
