Embodiment 1
[0029] Such as figure 1 , a surgical navigation probe, including a needle bar 1 and a positioning assembly connected to the needle bar 1, the positioning assembly includes an upper positioning block 2 and a lower positioning block 3 on the same plane, and the upper positioning block 2 and the lower positioning block The surface of 3 is provided with a grid-shaped positioning grid, and the color difference of the filling color of adjacent positioning grids is relatively large. The intersection of four adjacent positioning grids is the positioning point, and the upper positioning block 2 Two positioning points are formed on the top, and one positioning point is formed on the lower positioning block 3; the two positioning points on the upper positioning block 2 and one positioning point on the lower positioning block 3 constitute a main positioning noodle;
[0030] The needle bar 1 is a straight rod, and one of the positioning points on the upper positioning block 2 is parallel ...
Embodiment 2
[0056] Example 2, such as image 3 As shown, different from Embodiment 1, the needle bar is a straight bar without bending in the middle of the needle bar.
