Optical tracking structure for navigating surgical power system

Abstract

The invention relates to the technical field of medical instruments, in particular to an optical tracking structure for navigating a surgical power system. The structure comprises a connector for connecting and driving a surgical power instrument, and a navigation support is arranged on the connector. A plurality of reflective balls used for constructing a positioning surface for an optical tracking system are arranged on the navigation support in a following mode, an annular supporting surface is formed on the navigation support, and the plurality of reflective balls are distributed on the surface of the annular supporting surface in a surrounding mode. The optical tracking system performs optical tracking on the spatial position of a surgical power instrument within the angle range of 360 degrees through the plurality of reflective balls. According to the optical tracking structure for navigating the surgical power system, the tracking range of the optical tracking system on the surgical power instrument can be effectively enlarged, the navigation precision in the surgical process is ensured, and surgery navigation is smoother.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an optical tracking structure for navigating a surgical power system. Background technique [0002] At present, the optical tracking device clinically used for navigation surgery is mainly an optical positioning and tracking system produced by NDI Corporation of Canada. The positioning principle of this type of system is: the infrared light emitted by the binocular position sensor is irradiated on the surgical equipment or instruments equipped with tracking tools, and the small balls (also called reflective balls) on the tracking tools that can reflect infrared light will reflect the infrared light Reflected back to the position sensor and calculated by the built-in software of the system to obtain the position coordinates of the tracking tool (including the position and angle of the tracking tool), so as to realize the positioning and tracking of the corresponding su...

AI Technical Summary

Problems solved by technology

Such as the tracking tool disclosed in patent 200720012127.0, the optical tracking tool has only one positioning surface, and the positioning surface is a 180° plane, resulting in a very small tracking range. Simply put, the optical tracking system cannot track smoothly from the side Surgical power instruments, therefore, during the operation, the optical tracking system has a small tracking range for the surgical power instruments, which makes the surgical power instruments unable to be tracked stably and effectively, and the accuracy of navigation is also affected, which is not conducive to the smooth operation of navigation conduct
