Magnetic device applied to anastomosis of large and medium blood vessels

Abstract

The invention discloses a magnetic device applied to the anastomosis of large and medium blood vessels. The magnetic device finishes the anastomosis of the blood vessels with different vessels diameters by utilizing two permanent magnet anastomosis rings comprising permanent magnets and corresponding to the vessel diameters of the large and medium blood vessels to be anastomosed so as to avoid the shortcomings of narrow lumens, false aneurysms, anastomotic stoma seepage, low anastomosis speed and great complication number caused by manual suturing anastomosis, avoids the shortcomings of narrow anastomotic stomas, blood seepage, hematorrhea caused by the slippage of ligatures, local tissue granuloma and pseudo artery formation because the two permanent magnet anastomosis rings are opposite to each other and smooth to realize the neat suture of intimae of the blood vessels, ensures the anastomosis speed which is increased by proximately over 10 times compared with manual anastomosis, and avoids blow flows of tissues and organs being blocked for long to cause the congestion and edema of the tissues and the organs to further cause anastomosis errhysis.

Description

technical field [0001] The invention relates to a medical device, in particular to a magnetic device suitable for anastomosis of large and medium blood vessels. Background technique [0002] In traditional surgery, the manual anastomosis method proposed by Carrel is still used more than 100 years ago. Now it has become the mainstream vascular anastomosis technique, but it has not yet fully complied with the ideal principle of vascular anastomosis. Hemodynamics and internal environment are disordered, surgical trauma is large, and inflammatory mediators are released, especially when large and medium-sized arteries and veins need to be anastomosed during major operations, which can lead to organ congestion and edema due to long-term blockage of blood flow, resulting in anastomotic bleeding Or postoperative secondary hemorrhage due to ligature slippage, postoperative local granulation tissue reaction and hyperplasia may also be caused by the ligature remaining in the body, whic...

[0002] In traditional surgery, the manual anastomosis method proposed by Carrel is still used more than 100 years ago. Now it has become the mainstream vascular anastomosis technique, but it has not yet fully complied with the ideal principle of vascular anastomosis. Hemodynamics and internal environment are disordered, surgical trauma is large, and inflammatory mediators are released, especially when large and medium-sized arteries and veins need to be anastomosed during major operations, which can lead to organ congestion and edema due to long-term blockage of blood flow, resulting in anastomotic bleeding Or postoperative secondary hemorrhage due to ligature slippage, postoperative local granulation tissue reaction and hyperplasia may also be caused by the ligature remaining in the body, which aggravates the body injury of the patient; Various complications such as aneurysms affect the healing of the anastomosis, and manual anastomosis requires high surgical skills

These shortcomings are still affecting the long-term efficacy of various anastomotic operations involving blood vessels

But so far, there is no special device for blood vessel anastomosis except for manual anastomosis of blood vessels with sutures.
