Control method of catheter and guide wire for vascular interventional operation

Abstract

The invention discloses a vascular interventional operation catheter and guide wire control method, which belongs to the technical field of vascular interventional operations, and comprises the following steps: judging the initial positions of a catheter and a guide wire in combination with a DSA image, and withdrawing the guide wire into the catheter; the interventional surgery robot system controls the guide wire to retreat to the fluid injection position; in the process that the guide wire retreats to the corresponding position, fluid injection parameters are set; after the guide wire retreats to the corresponding position, the interventional surgery robot system starts to inject fluid into the target blood vessel; after fluid injection is finished, the interventional surgery robot system automatically pushes the guide wire into the initial position of the catheter. Through the integrated design of guide wire removal and fluid injection actions, the original manual operation process is integrated into system operation, so that the operation process and the operation time of a doctor are reduced, meanwhile, through cooperation of machines, the operation can be quantified, the operation is safer, more stable and more efficient, and then the safety and the efficiency of an operation are improved.

Description

Technical field [0001] The present invention belongs to the field of vascular interventional surgery techniques, in particular to a vascular interventional surgical catheter, a method of controlling the wire. Background [0002] At present, fluid injection (such as contrast agent, gel, etc.) is required during vascular interventional surgery, at which time the guide wire needs to be withdrawn from the catheter, and the operation of the undiding wire is basically done manually by the doctor, which undoubtedly increases the length of the operation and the workload of the doctor. [0003] Moreover, the existing vascular interventional surgery in the assisted state of robots has failed to effectively solve the problems of rapid withdrawal of guide wire and fluid injection, which undoubtedly increases the risk of surgery and reduces the efficiency of vascular interventional surgery. Contents of the Invention [0004] In view of the above problems, the object of the present invention ...

Problems solved by technology

[0002] At present, fluid injection (such as contrast agent, gel, etc.) is required during vascular interventional surgery. At this time, the guide wire needs to be withdrawn from the catheter, and the operation of withdrawing the guide wire is basically done manually by doctors. This type of operation undoubtedly increases the surgical cost. The length of time and the workload of doctors

[0003] Moreover, the existing robot-assisted vascular interventional surgery fails to effectively solve the problem of quick withdrawal of the guide wire and fluid injection, which undoubtedly increases the risk of surgery and reduces the efficiency of vascular interventional surgery
