Problems solved by technology

For cardiovascular interventional operations with more complex surgical procedures, the surgical training system with single-degree-of-freedom force feedback obviously cannot meet the requirements
Due to the lack of dedicated cardiovascular intervention virtual surgery simulation system, people have to use the existing virtual surgery simulation equipment

Abstract

The invention provides a cardiovascular interventional virtual surgery simulation system based on force feedback. The cardiovascular interventional virtual surgery simulation system comprises a displacement collecting unit, a force feedback mechanism, a motor driver, a processor and a computer, wherein the displacement collecting unit comprises a guide wire displacement collecting unit, a balloon catheter displacement collecting unit and a guiding catheter displacement collecting unit; and the force feedback mechanism comprises a guide wire force feedback mechanism, a balloon catheter force feedback mechanism and a guiding catheter force feedback mechanism. The cardiovascular interventional virtual surgery simulation system is used for simulating the movement sense and the force sense in the process of inserting guide wires, catheters and the like in vascular intervention therapy. The surgery accuracy is high, the repeatability is good, the training cycle of doctors can be shortened, and the surgical risk is reduced.

Description

technical field [0001] The invention relates to a virtual surgery simulation system, in particular to a force feedback-based cardiovascular intervention virtual surgery simulation system. Background technique [0002] Coronary Atherosclerotic Heart Disease (Coronary Atherosclerotic Heart Disease) is referred to as coronary heart disease. Convulsions) lead to heart disease caused by insufficient blood supply to the myocardium, resulting in hypoxia or even necrosis of the heart. Coronary heart disease is the most common type of disease caused by atherosclerosis in arteries and blood vessels, which seriously threatens human health. The treatment methods of coronary heart disease are usually divided into four types: exercise therapy, drug therapy, surgical operation and interventional operation. Among them, the curative effect of cardiovascular interventional therapy is rapid and significant, and the postoperative recovery period of patients is short. It has become one of the ...
