Problems solved by technology

The operation requires a certain degree of proficiency, so an abdominal aortic aneurysm stent-graft interventional surgery simulation device is needed, and the existing abdominal aortic aneurysm stent-graft interventional surgery simulation device cannot simulate the flow of blood, and cannot set active bending (Clinically, many patients have a large aneurysm neck angle and increased difficulty in surgical operation), which makes it impossible to imitate the complexity of the human aorta, and it is impossible to practice better to improve proficiency

Abstract

The invention belongs to the field of treatment of abdominal aortic aneurysm stent-graft, in particular to an interventional operation simulation device for abdominal aortic aneurysm stent-graft, including a support mechanism, the support mechanism includes a housing, a door, a handle 1, an operation hole, and the front part of the housing A door is connected through a hinge, a handle is installed at the front end of the door, and operation holes are formed on the top and bottom of the shell, and the supporting mechanism is equipped with a simulation mechanism for simulating human blood flow and a simulation mechanism for simulating abdominal aortic aneurysm. The mechanism and the simulation mechanism with different aneurysm neck angles, the casing and the blood vessel system are all transparent materials, which can make the whole process of releasing the covered stent visible. The present invention adopts the aortic blood flow simulation mechanism to simulate the flow dynamics of the auxiliary aneurysm blood, and adopts the abdominal aortic aneurysm simulation mechanism to bend various parts of the abdominal aorta to simulate the complex environment of the abdominal aortic aneurysm , so it can increase the difficulty to increase proficiency in the practice of surgery.

Description

technical field [0001] The invention belongs to the field of abdominal aortic aneurysm covered stent treatment, in particular to an abdominal aortic aneurysm covered stent intervention operation simulation device. Background technique [0002] The aorta is the largest arterial tube in the human body. It originates from the left ventricle of the heart, arches upwards to the right and downwards, and then descends the spine, branching out into many smaller arteries in the thoracic and abdominal cavities. The aorta is the main vessel, also known as the large artery, that carries blood to all parts of the body. Covered stents refer to metal stents coated with special membrane materials (polytetrafluoroethylene, polyester, polyester, polyurethane, etc.). It not only retains the function of the metal stent, but also has the characteristics of a membrane material, which can cover and isolate the aortic aneurysm and reduce the chance of aneurysm rupture. [0003] Abdominal aortic a...
