Needle holder is also called needle holding forceps. It is made of medical stainless steel materials and is widely applied in surgery and microsurgery. It is mainly for clamping suture needle to suture various tissues, and sometimes it is also for tying instruments.
Clamp the suture needle with the front part of the jaw of the medical needle holder, and clamp it in the area of about 1/3 to 1/2 of the distance between the end of the clamp and the needle tip. In most cases, the needle tip should be clamped to the left, but in special cases, it can be right. The stitches should be overlapped by 1/3, and the overlapped part of winding thread should also be placed in the needle tip to facilitate operation. Avoid clamping the inlay end with the needle holder, which is the weak link of the needle. When a round needle or a blade needle is used, clamp it at the far end of the needle as far as possible to avoid damaging the tip or edge of the needle.
The common methods of needle holding forceps are as follows.
The method of palm holding is also called grasping or fully grasping, that is, holding fine needle holder with the palm of the hand. This method is stable, easy to change the direction of the suture needle, suture smoothly and easy to operate.
The finger insertion method is a traditional method. That is, the thumb and ring finger are put into the clamp ring to control the opening and closing of the needle holding forceps with the finger movement force.
The palm fingering method is to put the thumb into the clamp ring, let the index finger on the front half of the forceps for support and guidance, and the remaining three fingers press the clamp ring and fix it in the palm. The thumb can move up and down to control the opening and closing of needle holder.
The surgeon makes the curved needle pass through the tissue with the curved needle driver. The needle holder must be made of corrosion-resistant, high-strength and high-quality alloy steel. The selection of needle holder should be considered as follows.
If the needle is very small, then the jaw of the surgical needle holder should be correspondingly small. If the needle is thick and large, then the mouth of the needle holder should be wide.
If the surgeon carries out deep body cavity surgery, it is necessary to select a longer needle holder.
Do not clamp the needle too tightly because the jaw of the straight needle holder may cause irreversible deformation, damage or bending of the needle. Always check the jaw of the needle holder. Do not allow the needle to shake, twist or turn, and the needle and needle holder should be mastered as a whole.
When the sterile needle holder is delivered, pay attention to the direction so that surgeons do not need to readjust before suturing the tissue. When submitting, the direction of the needle must be consistent with the direction of utilization. The suture should not be tangled, and the needle should be pulled out from the tissue. Be sure to submit the needle holder, not the hemostatic forceps, as the hemostatic forceps or other clamps may damage the needle. After the needle holder is used, the needle can not be separated from the needle holder. The needle held in the needle holder should be returned to the scrubbing nurse immediately. If one is returned and another is taken over, the loss of needles can be effectively avoided.
Suture needle holder is a common clinical instrument with high frequency. However, in practice, it is not recommended to replace it in function with any device (even if the structure of the front end of the device is similar to the needle holder). Unless the situation is extremely urgent, straight clamp can be applied for the same operation, but be careful. It may lead to slippage or direction change of bending needle due to loose clamping, as well as damage to needle holder and curved needle, thus injuring patient tissue or operator's hand.
