Embodiment Construction
[0017] The preferred embodiment of the propulsion mechanism of the vascular interventional surgery robot of the present invention is an end effector for a vascular interventional surgery robot, which includes an axial feed component for advancing the catheter, a circumferential axis for changing the advancing direction of the catheter Towards a rotating part and a detecting part for detecting the distance advanced by the catheter;
[0018] Among them, the detection part and the axial feed part are connected as a whole through a connecting rod and kept parallel, and the two feed and rotate synchronously; the axial feed part has a pair of synchronous and reverse-rotating active rollers to form a guide for the catheter. The first clamping arm; the detection part includes a pair of driven rollers to form the second clamping arm for the catheter; the double-arm clamping of the catheter is realized, and the purpose of synchronizing the helical advancement and detection of the cathete...
