Electromagnetic controllable occlusion system for celiac great vessels

Abstract

An electromagnetic controllability occlusion system for celiac great vessels comprises an internal magnetic vessel occlusion device, an external electromagnet element and central control equipment, wherein the internal magnetic vessel occlusion device corresponds to an external electromagnet element which is connected with the central control equipment; the internal magnetic vessel occlusion device is placed on the surface of an infrahepatic vena cava and used for pressing and occluding vessels; the external electromagnet element is integrated into an operating bed mattress and used for locating the internal magnetic vessel occlusion device and gradually increasing the current of the external electromagnet element; and occlusion of postcava or aorta abdominalis is realized through attraction between the external electromagnet element and the internal magnetic vessel occlusion device. The electromagnetic controllability occlusion system can be operated simply, conveniently, quickly and safely, avoids defects of longer operation time, vessel injury and the like, which are caused by vessel separation in an open appendectomy or laparoscopic surgery , and simultaneously solves the problem of instable systemic hemodynamics probably caused by a traditional vessel occlusion method.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and is suitable for blocking large abdominal vessels, namely abdominal aorta and inferior vena cava, in particular to an electromagnetic controllable blood vessel blocking system. Background technique [0002] In recent years, with the advancement of surgical technology, the development of related surgical instruments and equipment, and the application of various hemostatic drugs, the control of intraoperative bleeding has developed rapidly, especially the use of vascular occlusion techniques. In hepatectomy, all or part of the first hepatic portal block, hepatic vein block, and whole liver blood flow block have been applied clinically. It has been proved that intraoperative bleeding can be significantly reduced. In addition, in abdominal aortic aneurysm repair surgery, pelvic tumor and fracture surgery, abdominal aortic occlusion is also used to assist the successful completion of sur...

AI Technical Summary

Problems solved by technology

For the large blood vessels deep in the abdominal cavity, including the inferior vena cava and abdominal aorta, the traditional methods of exposure, separation, and blocking not only prolong the operation time, but also may cause iatrogenic vascular injury, especially with With the rapid development of minimally invasive surgery, more operations can be performed laparoscopically. Since hemostasis is more difficult under laparoscopy, it is more necessary to use vascular occlusion to prevent bleeding, and vascular occlusion under laparoscopy is more difficult than laparotomy. Surgery is more difficult, so innovative research on optimizing and improving vascular occlusion methods and related equipment has great clinical significance and development prospects
