Tectorial membrane bracket in medical care surgery and use method of tectorial membrane bracket

Abstract

The invention discloses a tectorial membrane bracket in medical care surgery and a use method of the tectorial membrane bracket. The bracket comprises reinforcement sutural margins, an artificial blood vessel tectorial membrane, a metallic framework, a tectorial membrane bracket main body, a roundabout involution opening, tectorial membrane bracket aorta arch sections and tectorial membrane bracket aorta lowering sections, wherein both ends of the tectorial membrane bracket main body are connected with the reinforcement sutural margins; the metallic framework is fixed on the tectorial membrane bracket main body; the artificial blood vessel tectorial membrane is attached to the metallic framework and the tectorial membrane bracket main body; the tectorial membrane bracket main body consists of the tectorial membrane bracket aorta arch sections and the tectorial membrane bracket aorta lowering sections; the roundabout involution opening is formed in the edge of the upper end of the middle of the tectorial membrane bracket main body. According to the invention, the time of a low temperature and circulatory arrest in the surgery is shortened, the possibility that spinal cords are damaged is reduced, and the restore of patients is facilitated.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a covered stent in medical operations and a method for using the same. Background technique [0002] For the condition that the three-branch vessels are intact, the stent-graft in the aortic arch artificial vascular surgery is currently used to replace the diseased aortic arch with artificial blood vessels. The artificial blood vessel was sutured to the ascending aorta, then the stent graft was implanted into the descending aorta, and finally the stent graft was implanted. However, because during the operation, it is necessary to suture the exposed metal stent segment and the artificial blood vessel at the end of the covered stent graft, the problem of bleeding at the suture point of the three-branch artificial blood vessel and the artificial blood vessel under long-term deep hypothermic circulatory arrest , which is one of the causes of postoperative death in patients. Moreover,...

Problems solved by technology

However, because during the operation, it is necessary to suture the exposed metal stent segment and the artificial blood vessel at the end of the covered stent graft, the problem of bleeding at the suture point of the three-branch artificial blood vessel and the artificial blood vessel under long-term deep hypothermic circulatory arrest , which is one of the causes of postoperative death

Moreover, this method has the following disadvantages: the stent is easily displaced under the impact of blood flow, and the treatment is difficult when the aortic arch and branch vessels are re-infected.
