AI Technical Summary

Technical Problem

Existing surgical systems are difficult to effectively distinguish and handle relatively important and unimportant sight loss events during the surgery, resulting in unnecessary warnings and surgical interruptions.

Method used

A handheld surgical system is designed, which includes a drive motor, a console, a tracking device, a tracking unit, a warning module and a control system. The control system differentiates and handles occlusion events based on this information by determining the attitude and boundary of the instrument.

Benefits of technology

It effectively reduces unnecessary warnings and surgical interruptions, improves the accuracy and efficiency of the surgery, and ensures that the surgeon's operation at critical moments is not disturbed by unimportant loss of sight.

Abstract

A handheld surgical system includes an instrument configured to be held in a hand of a user and including a drive motor. The instrument is coupled to a tracking device. The handheld surgical system also includes a tracking unit, a warning module, and a control system in communication with the tracking unit, the warning module, and the instrument. The control system is configured to track, with the tracking unit, a pose of the instrument in a known coordinate system, determine a boundary associated with a region of interest in the surgical procedure in the known coordinate system, control the warning module based on the boundary and the tracked pose of the instrument, determine that the tracking device has occurred an occlusion event, and determine that the tracking device has occurred an occlusion event. And control the drive motor based on the occlusion event, the boundary, and the tracked attitude of the instrument.
