Document Type and Number:
WIPO Patent Application WO/2023/061183
Kind Code:
A1
Abstract:
Provided in the present application are a medical catheter and a shape control system and control method therefor, a surgical robot, and a storage medium. The medical catheter comprises a first catheter, a second catheter, a plurality of guide wires and a driving device, wherein the plurality of guide wires are provided in the first catheter and the second catheter in a penetrating manner; a distal end of the first catheter is connected to a proximal end of the second catheter; the driving device comprises a plurality of driving members corresponding to the guide wires on a one-to-one basis; a proximal end of each guide wire penetrates through a proximal end of the first catheter and is connected to a driving member, and a distal end of each guide wire is connected to a distal end of the second catheter; and under the action of the driving members, the guide wires can extend and shorten in axial directions thereof, such that the second catheter can be bent in at least one direction. In the present application, the guide wires extending and shortening in terms of length in the axial directions thereof can be precisely controlled by the driving members, such that the direction and angle of bending of the second catheter can be precisely controlled, and thus precisely control the shape of the second catheter, thereby ensuring the smoothness of movement of the medical catheter in a human body.
