Title:
OPTICAL TRACKING TOOL FOR NAVIGATING SURGERY
Document Type and Number:
WIPO Patent Application WO/2017/036340
Kind Code:
A1
Abstract:
Provided is an optical tracking tool for navigating a surgery, comprising a mounting base (1). The mounting base (1) is provided with two to six supporting faces (2) thereon. Two or four reflective balls (3) are arranged on each of the supporting faces (2). A positioning surface (5) is formed by the four reflective balls (3) located on the same supporting face (2) or the four reflective balls (3) respectively located on two adjacent supporting faces (2). An included angle between surface normal vectors of two adjacent positioning surfaces (5) is 90°-140°. As compared with a tracking tool having a single positioning surface formed by four reflective balls in an existing technique, the optical tracking tool can considerably broaden an effective tracking range of a system, thereby improving system accuracy.
