This invention belongs to the field of medical device technology. Addressing the problems of poor catheter support and safety hazards in current catheters, this invention provides a novel catheter for interventional liver cancer surgery via the radial artery approach, comprising multiple sequentially connected catheter segments. Each catheter segment includes an elastic tube, and a support body and a restraint mechanism disposed within the elastic tube, with the support body and restraint mechanism connected. The support body in this invention provides axial and radial support to both ends of the elastic tube. At the vascular bend in the catheter segment, the internal restraint mechanism, when compressed by the vessel wall, causes a change in the volume of its internally packed, deformable components, thereby deforming the support body and reducing its internal support strength. This reduces the overall rigidity of the catheter segment at the vascular bend, allowing the catheter segment to conform to the lateral curvature of the vessel. Simultaneously, the deformed support body provides axial support to the elastic tube, preventing occlusion of the elastic tube lumen at the vascular bend.
