Problems solved by technology

[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 calcif...

Embodiment 1

[0043]The aorta block-free anastomotic auxiliary device described in this embodiment includes a gas delivery tube 1 and a working air bag 2 arranged at one end and communicating with it. The working air bag 2 in is filled by the water injector. The working airbag 2 is deflated in its non-working state and attached to the air delivery tube 1, and the working airbag 2 in the inflated state is located in the aortic blood vessel and supports the aortic blood vessel from the inside. The working state of the aortic block-free anastomotic auxiliary device according to the present invention is: the working airbag 2 is filled and its upper side 203 is close to the aortic intima, and the junction of the upper side 203 of the working airbag 2 and the aortic intima is located The periphery of the circumference of the aortic hole 4, to reserve a suture position at the circumference of the aortic hole 4; the air delivery tube 1 is used as the gas delivery channel of the working air bag 2 an...

Embodiment 2

[0054] The specific structure of the aortic occlusion-free anastomotic assisting device described in this embodiment is roughly the same as that of the aortic occlusion-free anastomotic assisting device described in Example 1, except that: The upper side 203 of the working balloon 2 connects the inner side 201 and the outer side 202 in an arc along the aortic intima. The auxiliary device in this embodiment is the improvement of Embodiment 1. The working airbag 2 is designed as an arc-shaped structure, which is more suitable for the aortic intima to ensure the blocking effect of the working airbag 2. It can be applied to patients of all ages and physiques. , but it is more suitable for patients with younger age, smaller aortic diameter or larger perforation diameter.

Embodiment 3

[0056] The specific structure of the aortic occlusion-free anastomotic assisting device described in this embodiment is roughly the same as that of the aortic occlusion-free anastomotic assisting device described in Example 1, except that the working airbag 2. In the filling state, it is asymmetrically arranged on the air delivery tube 1, that is, the junction point between the air delivery tube 1 and the inner surface 201 deviates from the center of the inner surface 201, and a mark is set on the circumference of the air delivery tube 1. One side of the trachea. The air delivery tube 1 and the inflated working air bag 2 are asymmetrically distributed, so as to adapt to the oblique insertion of the auxiliary device. Since the air delivery tube 1 inserted into the aorta has a different distance from the aortic intima, Therefore, the asymmetrically designed working balloon 2 enables the upper side 203 of the balloon to be in close contact with the intima of the aorta after the b...

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...
