BLADE DRIVE MECHANISM AND SYSTEM

WIPO Patent Application WO/2019/047061

A1

A blade drive mechanism and system, relating to the field of medical instruments. The drive mechanism comprises: a rotation member (1), a rope transmission member (2), a transmission rope (3), a steering member (4), and a pushing block (5); the rope transmission member (2) is linked to the rotation member (1); the steering member (4) is linked to the rope transmission member (2) by means of the transmission rope (3), and is used for making the transmission rope (3) form a blade transmission section (301) along the direction of movement of a blade (X); in addition, the pushing block (5) is simultaneously connected to the blade transmission section (301) and the blade (X). The present blade transmission mechanism drives the movement of the blade (X) by means of the cooperation of the rope transmission member (2), the transmission rope (3), and the steering member (4), increasing the movement speed of the blade (X) and ensuring the reliability and controllability of the movement of the blade (X). Relative to a screw and nut transmission method, the present blade drive mechanism structure is simple to manufacture, manufacturing precision is controllable, and the service life is long.
