Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.
A distal end, which is far away from the direction of an operator or a vascular interventional robot, i.e. the part of the catheter which enters the blood vessel when vascular interventional therapy is performed;
the proximal end, with respect to the distal end, is closer to the operator or vessel interventional robot, i.e. the portion of the catheter that enters the vessel after the catheter portion with respect to the front end when performing a vessel interventional procedure.
Example 1:
aiming at the problems that only one pre-bending section is arranged and cannot be suitable for the environment with large bending degree of the blood vessel, and the diameter of the catheter is increased by pulling the steel wire when a plurality of pre-bending sections are arranged; in order to solve the contradiction between increasing the bending angle and degree and influencing the blood vessel after increasing the diameter of the catheter, as shown in fig. 1, the embodiment provides a catheter for a vascular intervention robot, which comprises a distal pre-bending section 2 and a proximal bending section 3 arranged on a catheter body 1, wherein the distal pre-bending section 2 and the proximal bending section 3 are controlled by a traction steel wire 4, and the traction steel wire 4 is divided into a plurality of distal traction steel wires and a plurality of proximal traction steel wires; optionally, the proximal pulling steel wires and the distal pulling steel wires are 3, 6 pulling steel wires are uniformly distributed in the circumferential direction of the proximal bending section 3, and 3 distal pulling steel wires are uniformly distributed in the circumferential direction of the distal pre-bending section 2;
a plurality of steel wire holes 8 are formed in the inner circumference of the distal pre-bending section 2 and the inner circumference of the distal pre-bending section 3, and correspondingly, a plurality of steel wire holes are also formed in the catheter body 1; the proximal traction steel wire passes through a steel wire hole in the proximal pre-bending section 3 and then is fixed on the proximal bending section 3; the distal traction steel wire sequentially passes through a steel wire hole in the proximal pre-bending section 3 and a steel wire hole in the distal pre-bending section 2 and then is fixed on the distal pre-bending section 2; the fixation of the wire may be fixed to the respective wire fixation ring 12 by welding or other fixation means, it being understood that the wire fixation ring 12 is provided at the distal end of both the proximal pre-bent section 3 and the distal pre-bent section 2.
The distal end pre-bending section 2 and the proximal end bending section 3 are arranged on the catheter body, and the flexibility of controlling the bending of the catheter is improved through the two pre-bending sections, so that the requirements of adjusting the bending angle and the degree during vascular interventional therapy can be met; meanwhile, the device is used for controlling the distal traction steel wire of the distal pre-bending section 2 to pass through the steel wire hole of the proximal pre-bending section 3 and then enter the steel wire hole of the distal pre-bending section 2, so that all the traction steel wires 4 are positioned in the steel wire hole formed in the catheter, the phenomenon that the distal traction steel wire is arranged by increasing the whole diameter and the volume of the catheter is avoided, and the contradiction between the effect of increasing the bending angle and degree and the effect of increasing the diameter of the catheter on blood vessels is solved.

The rigidity of the proximal vertebra spring is larger than that of the distal pre-bending section, after the proximal bending section 3 is bent, the proximal vertebra spring is not easy to deform when the distal pre-bending section 2 is operated due to the larger rigidity of the proximal vertebra spring, so that the stability of the bending degree of the proximal bending section 3 is improved, and the vascular intervention treatment quality is ensured.
A guide wire hole 5 is formed in the middle of the catheter body 1; the far-end pre-bending section 2 and the near-end bending section 3 are provided with polytetrafluoroethylene layers 6 near the wire guide holes 5, and polyether block polyamide layers 9 far away from the wire guide holes 5; it will be appreciated that the thickness of the polytetrafluoroethylene layer 6 is much smaller than the thickness of the polyether block polyamide layer 9, and that the wire holes 8, the spiral leaf springs 7, etc. are provided in the polyether block polyamide layer 9; the polytetrafluoroethylene layer 6 reduces friction resistance between the inner wall of the guide wire hole 5 and the guide wire, so that the guide wire moves in the guide tube in a flow field, and the vascular interventional treatment quality is ensured.
A braiding wire 10 is arranged in the polyether block polyamide layer 9; specifically, the woven wire 10 is a stainless steel wire; the braided wire 10 comprises a plurality of arc-shaped sections, the arc top of each arc-shaped section is in contact with the polytetrafluoroethylene layer 6, the end part of each arc-shaped section is positioned at the steel wire hole 8, and the plurality of arc-shaped sections distributed on the radial direction of the catheter by the braided wire 10 greatly increase the supporting capacity of the catheter.

The working principle or process of the embodiment is as follows:
when the bending of the proximal bending section 3 is adjusted, the corresponding proximal traction steel wire is pulled, so that the bending angle of the proximal bending section 3 is adjusted; when the bending of the distal bending section 2 is adjusted, the proximal traction steel wire is kept still, and the corresponding distal traction steel wire is pulled, so that the bending angle of the distal bending section 2 is adjusted.
When the bending angle is excessively adjusted or the bending adjustment is canceled, the corresponding traction steel wire is loosened, and the corresponding bending section is restored to the bending angle meeting the requirement or the original state under the action of the spiral leaf spring 7.
