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

Abstract

The present invention relates to the technical field of medical instruments, in particular to an optical tracking structure for navigating surgical power systems, including connectors for connecting and driving surgical power instruments, the connectors are provided with navigation brackets, and the navigation The bracket is followed by several reflective balls used to construct a positioning surface for the optical tracking system. A ring-shaped support surface is formed on the navigation bracket, and several reflective balls are distributed around the surface of the ring-shaped support surface. The optical The tracking system performs optical tracking of the spatial position of the surgical power instrument in a 360° angle range through several reflective balls. The invention provides an optical tracking structure for a navigation operation power system, which can effectively improve the tracking range of the operation power instrument by the optical tracking system, ensure the navigation accuracy in the operation process, and make the navigation operation more smooth.

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...
