Artificial blood vessel perforator for Bentall surgery

Abstract

The invention relates to the field of medical apparatuses, and particularly discloses an artificial blood vessel perforator for Bentall surgery. The artificial blood vessel perforator comprises a straight handle and a perforating tip at the lower end of the handle. An indicating end is connected with the lower end of the handle. The perforating tip is obliquely arranged on one side of the handle.The indicating tip is obliquely arranged on the other side of the handle and is parallel to the perforating tip. The intraoperative artificial blood vessel perforating efficiency can be improved, andmeanwhile the position accuracy of formed side holes is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an artificial blood vessel puncher for Bentall operation. Background technique [0002] Bentall's procedure, also known as "ascending aortic replacement with aortic valve artificial vessel", is a surgical method for the treatment of ascending aortic aneurysms, and is suitable for patients with ascending aortic dissection aneurysms involving the coronary sinus or complicated by aortic valve insufficiency ;The operation can be performed by hypothermic extracorporeal circulation. The main operation steps are to insert the supplying blood vessel into the right femoral artery, insert the draining blood vessel into the right atrium, connect the artificial heart-lung machine for bypass, and clamp the distal end of the lesion when the body temperature drops to 33-35°C Ascending aorta, perfusing cardioplegia, freeing ascending aorta, resecting ascending aorta lesion, retaining its rear ...

AI Technical Summary

Problems solved by technology

[0004] In the existing operation, the operator generally uses a mechanical piercing type, an electric arc type, or an electric burning type puncher to punch a side hole on the artificial blood vessel; for the protection of the coronary artery, the coronary artery and the artificial blood vessel are separated during punching. A certain distance needs to be kept, and due to the lack of special indicating tools, and the folded structure of the artificial blood vessel, which is limited to the narrow operating area, the operator needs to repeatedly search for the perforation position on the artificial blood vessel, that is, repeatedly The actual operation of simulating (moving the eyes back and forth to aim at and estimating by visual acuity) the position of the coronary anastomosis is very difficult and takes a long time, which reduces the efficiency of the operation, and once the position of the side hole deviates too much, it is very difficult Coronary ischemia may be caused, and the operation will fail
