Embodiment Construction

[0055] Preferred embodiments of the present invention are described in detail below in conjunction with accompanying drawing:

[0056] A large blood vessel stapler of the present invention is composed of an anastomotic clip 1 , a support bracket 8 and an artificial blood vessel part 9 .

[0057] refer to figure 1 , figure 2 The spring clip is composed of a clamping part 21, a switch part 22 and a spring 23. There is an open ring-shaped cushion 12 in the clamping part, a ring-shaped fixing column 11 is arranged in the middle part of the clamping part, and a fixing rod 24 is provided in the switch part. The fixed rod can limit the movement of the switch part, and the switch part has a bayonet 25 for clamping the fixed rod and has a clip overlapping part 26 . The fixing rod 24, the bayonet 25 clamping the fixing rod and the clip overlapping portion 26 cooperate to fix the anastomotic clip. If the position needs to be changed after the anastomosis, the fixing rod 24 can be rem...

Abstract

The invention relates to a large blood vessel anastomat. The large blood vessel anastomat is characterized by comprising an anastomosis clamp fixed through a spring, another anastomosis clamp fixed through a tooth and a buckle, another anastomosis clamp made by a long-piece-shaped soft object, provided with hooks on one side and buckles on the other side and fixed through the hooks and the buckles, a cylindrical supporting support and an artificial blood vessel portion, a cushion can be placed in the anastomosis clamp fixed through the tooth and the buckle, a row of small round holes are formed on one side of the supporting support or on each of two sides of the supporting support, a groove can be formed in the middle of the supporting support, length of the supporting support is slightly smaller than that of each anastomosis clamp, an artificial blood vessel can be connected with the supporting support, the artificial blood vessel connected with the supporting support is divided into two sections including a thin-wall artificial blood vessel close to the supporting support and a thick-wall artificial blood vessel away from the supporting support, and a circular-truncated-cone-shaped thick-wall artificial blood vessel is connected at a position where the thin-wall artificial blood vessel is connected with the thick-wall artificial blood vessel.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to an instrument for large blood vessel anastomosis. Background technique [0002] In the prior art, there are surgical operations, interventional stents and drug treatments for the treatment of large vessel diseases. The definitive and effective treatment for large vessel diseases such as thoracoabdominal aortic aneurysm is surgery. For critically ill and / or complex disease patients, surgery is often the first choice, or even the only choice. But the problem now is that the operation is risky and requires high requirements for surgeons. From the perspective of surgery, the technique of anastomosis of great vessels is the key technique of surgery. How to complete vascular anastomosis safely and quickly is an important factor to improve the success rate of operation, reduce the mortality rate of operation and reduce postoperative complications. [0003] The current method of an...
