AI Technical Summary

Technical Problem

In traditional hip replacement surgery, the placement of the prosthesis is not ideal, resulting in poor surgical outcomes. Existing robot-assisted systems have complex motion control and are prone to errors, which may lead to safety accidents.

Method used

A surgical system is provided, including a cutting tool, a robotic arm, and a controller. The robotic arm is controlled by signals to switch between traction and stationary modes to ensure accurate positioning of the cutting tool and to assist in prosthesis installation using a pre-alignment range and alignment posture.

Benefits of technology

This technology enables precise fabrication of hip joint prostheses, reduces iatrogenic damage, and improves the safety and controllability of the surgery.

Abstract

The present disclosure discloses a surgical system for preparing a predetermined shape on a hip joint, comprising a cutting tool, a mechanical arm and a controller, the cutting tool is used for cutting bone tissue; the mechanical arm is used for holding the cutting tool and controlling the pose of the cutting tool; the controller is used for making the mechanical arm enter a traction mode when a first signal is received, and making the mechanical arm enter a static mode when the first signal is not detected, wherein the mechanical arm can move under external force in the traction mode, and the mechanical arm keeps the current pose of the cutting tool in the static mode; in the static mode, the controller is further used for controlling the mechanical arm to automatically adjust the cutting tool to an alignment pose associated with a target pose when a second signal is received. Through the surgical system, the preparation of the predetermined shape for installing the hip joint prosthesis can be safely and controllably assisted, and the preparation of the predetermined shape for installing the hip joint prosthesis can be accurately assisted.
