Abstract

A slave-end apparatus for an interventional robot includes: a body, a first drive mechanism, a second drive mechanism and a front clamper that are mounted on the body. In a case that a first guide wire runs into a first catheter, and the first catheter and the first guide wire are respectively clamped by the first drive mechanism and the second mechanism and move to a desired position on the body, the first catheter and the first guide wire are taken off from the first drive mechanism and the second drive mechanism, the front clamper clamps the first catheter to prevent movement thereof, such that a second catheter runs into the first catheter, a second guide wire runs into the second catheter, and the second catheter and the second guide wire are clamped by the first drive mechanism and the second drive mechanism and is pushed on the body.

Claims18

Dependent claims

A slave-end apparatus for an interventional robot, comprising:

a body, a first drive mechanism, a second drive mechanism and a front clamper proximal to the first drive mechanism that are successively mounted on the body;
wherein
the first drive mechanism is configured to clamp and rotate a first catheter and a second catheter, and the second drive mechanism is configured to clamp and rotate a first guide wire and a second guide wire;
and
wherein the front clamper is a fixed-position clamping device that does not advance or drive the first catheter, wherein:
after the first guide wire is inserted into the first catheter, the first catheter and the first guide wire are clamped and moved to a target position along an axial direction of the body;
the first catheter the first drive mechanism releases the first catheter and the second drive mechanism releases the first guide wire, and the front clamper clamps and holds the first catheter at a fixed axial position as a stable reference;
and
wherein, with the front clamper holding the first catheter stationary, the first drive mechanism is configured to clamp and advance the second catheter to guide the second catheter into the first catheter, and the second drive mechanism is configured to clamp and advance the second guide wire to guide the second guide wire into the second catheter.
