Multi-angle vascular anastomosis fixation device

Abstract

The invention discloses a multi-angle vascular anastomosis fixation device. The multi-angle vascular anastomosis fixation device comprises a device body; the device body is provided with a track; a first connecting rod and a second connecting rod are installed on the track in sequence; both the first connecting rod and the second connecting rod can slide on the track back and forth; the far end ofthe first connecting rod is hinged with a third connecting rod; the far end of the second connecting rod is hinged with a fourth connecting rod; the far end of the third connecting rod is connected to a first vascular clamp through a universal joint; and the far end of the fourth connecting rod is connected to a second vascular clamp through a universal joint. The multi-angle vascular anastomosisfixation device provided by the invention has the vascular clamps, which can slide on the linear track back and forth; a vascular wall can be pulled and fixed continuously and stably; the anterior and posterior walls of broken ends of blood vessels can be shown clearly; the proper vascular clamp can be selected and used according to a free blood vessel condition and its travelling angle; a support frame is arranged on the vascular clamp; the support frame has the function of opening a vessel cavity; endangium is not injured; multi-angle fixation also can be carried out; and in particular, thedevice can be used for pulling and fixing blood vessels travelling in different angles.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multi-angle blood vessel anastomosis fixing device. Background technique [0002] It is known that when performing blood vessel-related operations, it is often necessary to cut off the blood vessel to a certain length, and then draw its two broken ends together and perform end-to-end anastomosis. In portal hypertension or some other special cases, end-to-end anastomosis or end-to-side anastomosis of two different blood vessels is often required to achieve shunt or bypass. Now, when performing end-to-end or end-to-side anastomosis, the chief surgeon needs to use two vascular clips to clamp the two ends of the blood vessel respectively. One of the assistants pulls the vascular clips together with both hands, and the other uses vascular forceps. The vessel wall is lifted to expose the lumen before delicate anastomoses can be performed. During the anastomosis, the ass...

Problems solved by technology

The designs of the above-mentioned prior art are all aimed at separating a blood vessel and then pulling and fixing the two ends together with a device. These designs can only be used for anastomosis of the anterior wall of the blood vessel relatively conveniently, but are not suitable for the anterior wall of the blood vessel. Exposure and anastomosis of the wall

Moreover, the lumen of the broken end of the blood vessel is empty and flat when there is no blood filling. Although some patents have designed support devices used in the blood vessel lumen, they will cause varying degrees of damage to the intima of the lumen, and when the suture is completed, Difficulty removing the device from the lumen of the vessel, making these devices less practical to operate

In addition, there is currently no suitable design for fixing two non-180-degree blood vessel stumps.

[0004] Therefore, the existing vascular anastomosis fixer cannot be more flexible, more effective, safer, and more convenient to pull and fix the two blood vessels under various walking conditions.
