Description

Blood vessel is cut for vascular bypass technique

Technical Field

The utility model relates to an instrument of using in the blood vessel bridging operation, in particular to blood vessel scissors for the blood vessel bridging operation belongs to medical instrument technical field.

Background

A fish mouth-shaped incision is required to be cut on a receptor blood vessel with the diameter of only 1mm in the vascular bypass surgery of the cerebral surgery, and a fish mouth-shaped incision is cut on a blood vessel wall vertical to the trend of the blood vessel under a microscope by adopting common blood vessel scissors at present. Because the common vascular scissors adopt the straight blades, doctors need to continuously change the shearing angle to finish the operation for many times during the operation, the separation of the inner membrane and the outer membrane of the vascular wall is easy to form, and the anastomosis is easy to fail; and because the blood vessel is thin and smooth, the operation difficulty is high, the whole blood vessel can be cut off by accident, even if the cutting is finished, the incision is not neat, and the later stage suture difficulty and suture effect are seriously influenced. The recipient blood vessels that normally need to be bridged are often located in a deep surgical field, so that ordinary vascular scissors cannot go deep into them and perform the cutting of the fish-mouth-like incision.
