Problems solved by technology

[0004] The technical problem to be solved by the present invention is that in the traditional vascular surgery training system, not only the catheter is limited by the operating speed of the operator, but also the trainee doctor lacks operating experience. Therefore, the blood vessel wall and the catheter tip are prone to collision. The purpose is to provide motion-based scaling. The vascular interventional surgery training system solves the problem of vascular tissue damage caused by the collision between the vessel wall and the catheter tip due to the lack of operating experience of the trainee doctors during the vascular interventional surgery training process

Abstract

The invention discloses a blood vessel interventional operation training system based on movement scaling. The system comprises an operation device and a visual device, wherein the operation device comprises a catheter, an axial operation structure driving the catheter to perform axial movement, and a guide structure driving the catheter to perform rotation movement, a first control device controlling the axial operation structure to run is arranged in the guide strucutre, and a second control device controlling the axial operation structure to run is arranged in the visual device. According to the system, by utilizing the catheter movement scaling principle, aiming at the blood vessel interventional surgery simulated operation carried out by surgeons, the reasonable running scheme of thecatheter is designed, the effective tactile feedback in the horizontal direction is also provided, and therefore, the problem that during the blood vessel interventional operation training process, due to the fact that a trained doctor is lack of operation experience, collision is generated between the blood vessel wall and the sharp end of the catheter, consequently, injuries are caused to the blood vessel tissue is solved.

Description

technical field [0001] The invention relates to a training system for vascular interventional surgery, in particular to a training system for vascular interventional surgery based on motion scaling. Background technique [0002] At present, most of the catheter operation training systems for vascular interventional surgery use virtual reality technology (VR, virtual reality) to simulate the operation of the catheter in the blood vessel. However, doctors lack a real blood vessel insertion environment, and there is no real-time tactile feedback to remind doctors of the catheter insertion process. Whether an obstacle is encountered, whether a collision occurs. When a collision occurs but there is no timely tactile feedback, the doctor cannot react quickly to correct his operation, so it is easy to cause blood vessel damage. At the same time, the entire vascular interventional operation requires the doctor to operate quickly and accurately. [0003] Most of the existing traini...
