一种适用于大血管吻合的磁性装置A magnetic device suitable for anastomosis of great vessels

技术领域technical field

本发明涉及一种医疗器械，具体涉及一种适用于大血管吻合的磁性装置。The invention relates to a medical device, in particular to a magnetic device suitable for anastomosis of large blood vessels.

背景技术Background technique

传统手术中大血管吻合却仍沿用100多年前的手工吻合方法，现在成为主流的大血管吻合技术，虽然在缝合材料的选择上有了很大的进步，但是这种传统的手工缝合方法仍未能完全符合理想的血管吻合原则，不仅吻合速度慢，还可能导致术中出现严重的血流动力学及内环境紊乱，手术创伤较大，炎症介质释放，特别是在重大手术中需吻合体腔内深处的大血管时，可因长时间阻断血流而导致器官缺血坏死，或淤血水肿致吻合口渗血，或术后因结扎线滑脱而出现继发性大出血，术后还可因结扎线在体内存留而引起局部肉芽组织反应和增生，加重了患者机体损伤；另外还可能导致血管壁的损伤形成假性动脉瘤等各种并发症，影响吻合口愈合，而且手工吻合还需要手术者具有较高外科手术技巧。这些缺点至今仍然在影响着各种涉及血管吻合手术的长期疗效。但目前为止除了术中利用缝线手工吻合血管外就只有简单的圆柱状血管吻合的装置，这种圆柱状结构不便于手术过程中的手术器械夹持固定，特别是非常不利于体腔深部的大血管吻合操作，造成手术吻合时间长且吻合难度大的缺点，严重的还会引发血管吻合不成功从而导致血管破裂引发失血过多的后果。In traditional surgery, the manual anastomosis method more than 100 years ago is still used, and now it has become the mainstream technique of large vessel anastomosis. Although great progress has been made in the selection of suture materials, this traditional manual suture method has not yet been established. It can fully comply with the ideal principle of vascular anastomosis. Not only is the anastomosis speed slow, but it may also lead to severe hemodynamic and internal environment disturbances during the operation, large surgical trauma, and release of inflammatory mediators, especially in major operations that require anastomosis in the body cavity. In the case of deep large blood vessels, long-term blockage of blood flow may lead to organ ischemia and necrosis, or congestion and edema may cause bleeding at the anastomosis, or secondary bleeding may occur due to slippage of the ligature after surgery. The ligature stays in the body and causes local granulation tissue reaction and hyperplasia, which aggravates the body injury of the patient; in addition, it may cause damage to the blood vessel wall to form various complications such as pseudoaneurysm, which will affect the healing of the anastomosis, and manual anastomosis requires surgery Those with high surgical skills. These shortcomings are still affecting the long-term efficacy of various vascular anastomosis operations. But so far, except for the manual anastomosis of blood vessels with sutures, there is only a simple cylindrical blood vessel anastomosis device. This cylindrical structure is not convenient for clamping and fixing surgical instruments during the operation, especially very unfavorable for large and deep parts of the body cavity. The vascular anastomosis operation has the disadvantages of long and difficult anastomosis, and in severe cases, it may lead to unsuccessful vascular anastomosis, resulting in rupture of blood vessels and excessive blood loss.
