AI Technical Summary
Existing hepatobiliary stone removal devices are prone to falling off when dealing with larger stones, while they are difficult to secure for smaller stones, increasing the difficulty of the surgery.
A stone retrieval device for hepatobiliary surgery was designed. The rotating rod drives the rotating plate to push the transmission rod, so that the sleeve separates and moves to both sides of the stone. After being released, the spring pushes the sleeve to close and clamp the stone. The sleeve and the stone retrieval cap are used to fix the stone.
It effectively prevents stones from falling out during the removal process, ensuring the smooth progress of the stone removal operation and reducing the difficulty of the surgery.
