在导航辅助手术期间监控偏移的系统
By using a locator coordinate system and a variable-speed motor in the navigation system, combined with the registration of the instrument tracker and the patient tracker, the position of the surgical instruments relative to the bone can be monitored in real time. This solves the problem that traditional navigation systems cannot monitor deviations, and improves the accuracy and safety of the surgery.

AI Technical Summary
Traditional navigation systems, when used without the assistance of robotic manipulators, cannot effectively monitor the deviation of surgical instruments relative to anatomical structures, leading to potential misplacement problems.
A navigation system with a locator coordinate system is used. Through the registration of the instrument tracker and the patient tracker, combined with the variable speed motor, the position of the instrument tip relative to the bone is monitored. The controller and navigation system detect the deviation and trigger an alarm or cut off the power supply when the deviation exceeds the threshold.
This technology enables real-time monitoring of tool offset relative to anatomical structures during surgery, ensuring correct placement of surgical tools, reducing surgical risks, and improving the accuracy and safety of the navigation system.
