Abstract

The invention relates to an optical fiber catheter one-way stepping device and a driving system, belongs to the field of ablation operation devices, and solves the problems that a stepping device in the prior art is inaccurate and unstable in displacement and cannot be used in a nuclear magnetic environment. An optical fiber conduit one-way stepping device comprises a driving assembly and a stepping assembly, and the driving assembly is used for driving the stepping assembly to move; the stepping assembly comprises a machine base, a driving stepping part and a driven stepping part, the driving stepping part and the driven stepping part are arranged in the machine base and are mutually meshed and connected in a ratchet wheel and ratchet mode, and the driving assembly drives the driving stepping part to drive the driven stepping part to conduct one-way stepping. The driven stepping part drives the optical fiber conduit to realize synchronous one-way stepping motion; the precision and the stability are improved by driving the optical fiber conduit to move unidirectionally and equidistantly.
