[0038] The upper detection window 31 is a variable-diameter structure gradually reducing in diameter towards the upper photoelectric sensor, and the lower detection window 41 is a variable-diameter structure gradually reducing in diameter towards the lower photoelectric sensor.

[0039] The bottom of the upper shell and the top of the lower shell are connected by screws.

[0040] The application scenarios of the utility model are as follows:

[0041] In use, the signal connector 21 is connected with a data processor, then a guide wire is passed through the wire channel 7, at this time, if the guide wire is moved and rotated, the increments of the guide wire movement and rotation in this period can be read on the data processor, and then the movement distance and rotation angle of the guide wire relative to the original point are calculated and transmitted to the end of the vascular interventional robot for control.
