Needle holder (Needle Holder) is also called needle holder. It is mainly used to clamp various needles to sew various tissues. Sometimes used for knotting of instruments. It is advisable to use the tip of the needle holder to clamp the junction of the middle and the rear 1/3 of the needle. In most cases, the needle point to be clamped should be to the left, and in special cases it can be to the right. The thread overlap is also placed in the needle mouth. To facilitate the operation, if the needle is clamped in the middle of the needle holder, it is easy to break the needle. The methods of holding needle pliers are: ^[1]

1. Mastering method: It is also called grasping or full grasping, that is, grasping and holding the needle pliers by hand as shown in Figures 1-15. The clamp ring is closely attached to the great intermuscular muscle, and the thumb, middle finger, ring finger and little finger are pressed on the handle of the forceps respectively. The last three fingers are fixed together, and the index finger is pressed on the proximal axis of the needle-holding forceps. The thumb and the big fish muscles and the metacarpophalangeal joints are used to expand the teeth, open the tooth clasp on the handle ring of the needle clamp, loosen the tooth clasp, and control the opening of the needle clamp to hold the needle. When closed, the thumb and the great intermuscular muscles and the rest of the metacarpophalas are about to be locked. This method is stable and easy to change the direction of the suture needle, the suture is smooth, and the operation is convenient.

2. Fingertip law is the traditional law enforcement (Figure l ~ 16). Use your thumb and ring finger to fit into the ring of the pliers, use the force of your fingers to control the opening and closing of the needle-holding pliers, and control the range of action when opening and interfering. The method of using the middle finger to insert the clamp into the clamp ring is far from the fulcrum and has poor stability, so it is a wrong law enforcement (Figure 1-17).

3. Palm fingering: Put your thumb into the clamp ring, press your index finger on the front half of the clamp for support and guidance, and fix the remaining three fingers with the clamp ring in the palm. The thumb can be opened and closed up and down to control the opening and closing of the needle clamp (Figure 1-18).

Needle holders are common clinical devices and are used very frequently. However, it is never recommended to use any device (even if the front end of the device is similar in structure to a needle holder) to replace it functionally. Unless the situation is extremely urgent, the same operation can be performed with straight-line forceps, but care must be taken. This may cause the looper to slip or change direction as well as damage to the needle holder and looper due to improper clamping. Injury to the patient's tissue or the operator's hand.
