AI Technical Summary
Technical Problem
Existing manual laparoscopic anastomosis devices suffer from problems such as easy jamming during drive operation and insufficient stability.
Method used
It adopts a linear feed drive structure design, which uses a one-way lever and elastic element in conjunction with a sawtooth drive slider to convert the rotation of the handle into linear feed motion of the operating lever. The unidirectional motion of the drive slider is optimized by a reset mechanism to ensure stability.
Benefits of technology
It effectively solves the problem of easy jamming during drive operation and improves the operational stability and reliability of manual laparoscopic anastomosis device.
