What Is the Role of the Needle-holder in Suturing?

Surgical needle holder is an important suture instrument for postoperative suture. Needle holder instrument belongs to a kind of medical device, which is composed of needle holding teeth and handle. There are scissors at the inner end of needle holding teeth close to the handle, and there are scales on the handle. With this structure, the operation is convenient, the operation time is short, and the incidence of postoperative infection is reduced.

 

 

1. Method of Needle Holder Clamping Needle

The method of needle holder with scissors clamping needle mainly includes the following contents.

 

(1) The thumb and ring finger are inserted into the two holes of the needle holder respectively, the middle finger is placed on the ring handle of the ring finger, and the index finger is pressed on the shaft of the needle holder, which is more stable.

 

(2) Then the top of the needle holder is to clamp one third of the suture needle tail.

 

(3) Start the suture operation and select the appropriate suture point and angle.

 

(4) Pay more attention to observation during suture to avoid objects left in patients.

2. How to Use Needle Holder Correctly

The conventional way to hold the needle is to insert the thumb and ring finger into the ring of the ethicon needle holder respectively, and the index finger holds up the front end of the needle holder to increase the stability. When the wound is sutured, choose the appropriate point and angle of the needle. At the beginning of learning, one should preset ideal points for the needle in and out. Control the needle in and out, and strive to achieve the ideal points When suturing the wound.

 

The main point of suture is to rotate the wrist according to the arc of the needle, so that the needle passes through the tissue and the needle tip passes through the predetermined position. Pay attention to the enough length of the needle for pulling out the needle. Sometimes when the tip of the needle is just exposed, it stops pushing, which will be difficult to pull out the needle. The needle should also be pulled out according to the arc of the needle to avoid tearing the tissue.

 

For deep suturing, hold the back of the needle holder with fingertips to complete the sewing and loosening actions. It is not necessary to insert the fingers into the rings so that the length of the needle can be fully utilized for deep suture. The other method is to hold the middle part of the needle holder by hand, which is convenient for suture at any angle within 360 ° range, especially some unconventional angle suture. However, this operation requires the finger to be retracted into the ring to release the needle holder to pull out the needle after the suture operation is completed. This process requires that the hand should not shake and the needle holder has no displacement, which is a real challenge for beginners.

 

When suturing, keep the fine needle holder parallel to the incision. Since the needle clamped on it is held at 90 ° to the needle holder, the suture and incision will be vertical. When suturing, the palmar surface of the operator holds the needle holder downward so that the needle tip is aligned with the needle insertion point at an appropriate angle, then the wrist rotates 180 ° along the arc of the needle, and the palm is just upward to complete the suture. The whole movement is in one breath.

3. Interaction between Needle Holder and Suture Needle

(1) Suitable size needle holder

 

(2) The pressure exerted on the needle by the long needle holder is too large, resulting in the careless straightening of the suture needle.

 

(3) The needle holder is too small to rotate around its long axis.

 

The needle clamping position of medical needle holder is relatively short. When the needle holder is opened, it can be seen that there are crossed twills. Some have vertical grooves, and some do not. For example, JZ needle holder has grooves, but JH needle holder has no grooves. However, the sterile needle holder should not be used to clamp the tissue because of its twill characteristics. The damage will be very serious, so it must be paid attention to.
