[0002] Surgical suturing is to sew up or reconstruct the passage of tissues and organs that have been cut or broken by trauma to restore their functions. Suturing is the basic condition to ensure good healing and is also one of the important basic operation techniques of surgical operations. General medical needle holders are surgical tools used in clinical medicine and surgical operations. Clamping sutures suitable for a variety of tissues are sometimes also used for instrument knotting;
[0003] Generally, the tip of the needle holder of a medical needle holder is clamped at the intersection of the middle and the back 1 / 3 of the needle. In general, the tip of the needle should be facing left, and in rare cases it can be facing right. The sutures should overlap by 1 / 3, and the overlapping part should also be placed inside the needle. For the convenience of work, if the needle is placed in the center of the needle holder, it is easy to damage the needle;

When clamping the suture needle and replacing the clamping needle holder for suturing, the suture needle is easily deflected or shaken, thereby affecting the surgical suturing operation. After the suture needle is deflected, it is not in a perpendicular state with the chuck, which also affects the surgical suturing operation, increases the doctor's pressure, makes the operation time longer, and affects the use effect.
