Description

Blood vessel stitching instrument

Technical Field

The invention relates to a blood vessel stitching instrument, and belongs to the technical field of surgical stitching.

Background

A needle is an instrument for suturing various tissues, and is composed of three basic parts, i.e., a needle tip, a needle body, and an eye. The needle tip is divided into a round head, a triangular head and a shovel head according to the shape: the needle body has three types of nearly circular, triangular and shovel shapes. The needle eye is a hole for leading wires and comprises a common hole and a bullet machine hole. Round needles are classified into 1/2 and 3/8 radians according to their radians, and the larger one is usually used in deep tissues. The second most common needle is a suture with the suture at the very end, so that the suture can only be made once in one direction, and then the cycle of suturing is repeated.

The surgical suture method has various types and different classifications, but the surgical suture steps are basically consistent, namely, firstly, the left hand is held with a dental forceps, the skin edge is lifted, the right hand is held with a needle forceps for clamping the needle thread, the needle forceps are screwed in from the outside by the force of the wrist arm, and the needle is penetrated into the soft tissue such as the large blood vessel or the intestinal canal along the radian of the needle for continuous suture. The steps show that the doctor can realize the suture only by matching the tooth forceps and the needle forceps, the requirements on manipulation, force and the like are met, the general operation time is long, the physical strength of the doctor is penetrated, and the reciprocating and circulating process is complicated.

In the process of suturing blood vessels at ordinary times, the suture needle is very tiny, the needle thread is difficult to find after being separated from a needle holder in the suturing process, and in the general continuous suturing process of anastomosing the blood vessels and the intestinal tracts, the suture needle passes through the blood vessels in the specific step 1; 2. Withdrawing the forceps holder suture needle; 3. adjusting the proper angle of the needle holder and the suture needle again; 4. the suture is again passed through the vessel, and so forth. The angle of the needle holder and the suture needle is often adjusted again in the middle, which takes most of the time of the whole process, and especially for small blood vessels, the risk of tearing off the blood vessel exists when the sight of an operator leaves the main blood vessel in the suture process.
