AI Technical Summary
When existing suture locking devices are used to fix the sutures by pulling during surgery, the palms tend to get sore, leading to unstable force application and situations where too much or too little force is applied.
It adopts a threaded rod and fixed head structure. By rotating the threaded rod, the compression block is driven to move. Combined with anti-slip pads and detachable components, the suture is stably locked by the cooperation of elastic steel clamps and locking blocks.
The operation is more stable, avoiding the problem of unstable force applied by the palm, and improving the reliability and stability of the suture fixation.
