具有力反馈的心血管介入虚拟手术模拟器的研发

The Simulator Development of Cardiovascular Interventional Virtual Surgery with Force Feedback

目前我国介入手术医生的总量远远不能满足冠心病患者的治疗需求,运用新的心血管介入手术训练手段来加快医生的培养显得尤为迫切,故开展心血管介入虚拟手术系统的研究有重要意义.针对心血管介入虚拟手术模拟器进行研发,对心血管介入虚拟手术力反馈模拟器进行总体设计,该文设计了心血管介入手术介入导丝、导管的运动功能、力反馈功能模块的机械结构与控制系统,设计了X光透视开关、造影剂注射剂量采集、球囊加压气压采集等辅助介入操作仿真模块.研究表明:集成的心血管介入手术模拟器系统满足医学培训的需要.

The total amount of interventional surgeons in our country is far from meeting the treatment demands of patients with coronary heart disease,so it is quite urgent to develop new cardiovascular interventional training methods to speed up the training of doctors,therefore,it is important to study of cardiovascular interventional virtual surgery system. Aiming at the virtual surgery simulator for cardiovascular intervention to develop,the overall design of the cardiovascular interventional virtual surgery force feedback simulator is implemented. The movement function of the catheter,mechanical structure and control system of force feedback function are designed,and a series of auxiliary intervention operation simulation modules are designed including X-ray perspective switch,contrast agent injection dose collection system and balloon pressurized air pressure acquisition,and so on. The studies show that the integrated cardiovascular interventional simulator system meets the demands of medical training.
