Optionally, the first marker 21 is a reflective marker sphere, so that the optical positioning system can easily collect the reflected light reflected by the first marker 21 through the spherical first marker 21, and the spatial position of the first marker 21 can be conveniently calculated; the second marker is a deformable body, and the MRI system can easily identify the deformable body, so that the surgical instrument can be conveniently positioned in the MRI system.

Further alternatively, the first marker 21 has a second receiving cavity that can be filled with the second marker, so that the combined use of the optical positioning system and the MRI system can also be achieved in combination with the container 22 and the first marker 21 receiving the second marker.
