Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a multi-angle blood vessel anastomosis fixing device.
Background
It is known that in the case of vascular-related surgery, it is often necessary to cut a certain length of the vessel, then to draw the two severed ends together and then to perform end-to-end anastomosis. In portal hypertension or other special cases, it is also often necessary to perform end-to-end or end-to-side anastomosis of two different vessels for the purpose of diversion or diversion. At present, when a main scalpel performs anastomosis at the end or the end side of a blood vessel, two vascular clamps are required to be clamped at the two ends of the blood vessel respectively, one assistant draws the vascular clamps together with two hands, and the other assistant lifts the blood vessel wall with the vascular clamps to expose the lumen, so that a fine anastomosis operation can be performed. When anastomosis is carried out, an assistant needs to adjust the angle of the blood vessel clamp in due time, and particularly when two blood vessels which do not run at 180 degrees are anastomosed, if the two hands of the assistant cannot rotate and fix the blood vessel clamp in a very coordinated and consistent manner so as to clearly expose the front wall and the rear wall of the blood vessel and keep a certain time, the consistency of the suture needle distance cannot be ensured, the blood vessel wall is very easy to tear, the blood vessel is twisted, and the chances of lumen stenosis and thrombus formation are increased.

In addition, no suitable design for fixing two broken ends of a blood vessel running at an angle other than 180 degrees exists at present.
Therefore, the existing blood vessel anastomosis fixator can not pull and fix two blood vessels under various running conditions more flexibly, more effectively, more safely and more conveniently.
