In-vitro training and testing system for percutaneous coronary interventional surgery

Abstract

The invention discloses an in-vitro training and testing system for percutaneous coronary interventional surgery. The in-vitro training and testing system comprises an operation platform, a constant-temperature box, a display, a sealed constant-temperature blood collecting box and a heart simulating device, wherein the constant-temperature box simulates the in-vivo environment of a human body, andthe display is connected with the constant-temperature box; the heart simulating device comprises a sealed rigid container, a piston communicated with the rigid container and a heart model arranged in the rigid container; the heart model is connected with an aorta model and a right pulmonary vein simulating pipeline communicated with the blood collecting box; left and right coronary artery modelsare connected to one end of the aorta model, and the far end of each coronary artery model is communicated with the blood collecting box through a silica-gel soft tube; the other end of the aorta model is communicated with one end of an artery simulating tube, the other end of the artery simulating tube is communicated with one end of a femoral artery blood vessel simulating section, and the other end of the femoral artery blood vessel simulating section is communicated with the blood collecting box. The in-vitro training and testing system has the advantages that the interventional surgery scene is restored, the surgery learning time of doctors is shortened, and the operation level of the doctors can be improved.

Description

technical field [0001] The invention belongs to the technical field of medical teaching and training equipment, and in particular relates to an in vitro training and testing system for percutaneous coronary intervention. Background technique [0002] With the development of social economy, the national lifestyle has undergone tremendous changes. Especially with the aging of the population and the acceleration of urbanization, the prevalence of risk factors for cardiovascular diseases in China has become more and more obvious, leading to a continuous increase in the number of cardiovascular diseases. The number of patients with cardiovascular disease will continue to increase rapidly in the next 10 years. According to the "China Cardiovascular Disease Report 2016", at present, cardiovascular disease death accounts for the first place in the total death of urban and rural residents, with 45.01% in rural areas and 42.61% in cities. About 40% of the deaths from cardiovascular ...

Problems solved by technology

Although interventional surgery is already a fairly safe operation in many hospitals, it is still a traumatic and dangerous examination and treatment. In addition, the surgical operator is unfamiliar with the operation technique, and there is a possibility of careless operation or mistakes. It can cause vasospasm or even coronary artery perforation, which can endanger the life of the patient in severe cases. Therefore, it is very important to strengthen the in vitro training of percutaneous coronary intervention.

However, the training products in the prior art cannot provide realistic situational teaching and training, cannot accurately simulate some emergencies in the interventional operation process, and cannot provide an effective evaluation mechanism for the training results, which has great limitations
