Aorta blocking-free anastomosis auxiliary device and using method thereof

Abstract

The invention discloses an aorta blocking-free anastomosis auxiliary device and a using method thereof. The aorta blocking-free anastomosis auxiliary device comprises an air conveying pipe and a working air bag arranged at one end of the air conveying pipe and communicated with the air conveying pipe, and the working air bag is inserted into an aorta from the aorta punching position; when the working air bag is in a full state, the upper side face of the working air bag is tightly attached to the aorta intima, the joint of the upper side face of the working air bag and the aorta intima is located on the periphery of the circumference of the aorta hole, and a suture position is reserved on the circumference of the aorta hole. The device is simple in structure, the aorta anastomosis device is simple in structure and convenient to use, a conventional surgical suture mode is broken through, namely anastomosis (suture) of the aorta can be completed under non-blocking of the aorta, normal flowing of blood in the aorta during surgery is guaranteed, damage caused by insufficient blood supply of organs of a patient under complete blocking of the aorta is avoided, blood loss in the surgicalsuture process is reduced, and the device is more suitable for aorta calcification patients.

Description

technical field [0001] The invention belongs to the technical field of surgical auxiliary devices, and in particular relates to an anastomotic auxiliary device without occlusion of the aorta and a use method thereof. Background technique [0002] In the process of aortic anastomosis, the existing operation method mostly uses vascular blocking forceps to block the upstream and downstream of the aorta, and after the aorta is perforated, it is sutured with the radial artery or the target blood vessel at the aortic hole. Under some operation methods, it is very easy for patients with vascular calcification to damage blood vessels or cause calcified plaques in blood vessels to fall off and cause embolism; but if the aorta is not blocked, due to the high blood pressure in the aorta, a large amount of blood will be ejected from the aortic hole Therefore, how to reduce the blood loss in patients and quickly suture the aorta under the premise of reducing the damage to blood vessels i...

[0002] In the process of aortic anastomosis, the existing operation method mostly uses vascular blocking forceps to block the upstream and downstream of the aorta, and after the aorta is perforated, it is sutured with the radial artery or the target blood vessel at the aortic hole. Under some operation methods, it is very easy for patients with vascular calcification to damage blood vessels or cause calcified plaques in blood vessels to fall off and cause embolism; but if the aorta is not blocked, due to the high blood pressure in the aorta, a large amount of blood will be ejected from the aortic hole , affecting surgical suturing; therefore, how to reduce a large amount of blood loss in patients and quickly suture the aorta under the premise of reducing blood vessel damage is a difficult problem for medical staff
