Clinically, the method of suture removal differs depending on the way the patient is stitched. First, if the patient takes a non-absorbable thread for interrupted suturing of the incision, when the wound is completely healed, it is necessary to pull the knot of the suture, cut the short silk thread from the incision at the root of the knot, and slowly pull out the silk thread in the direction of the suture to achieve the purpose of stitch removal. If there is a large resistance in the process of pulling the knot, it can be rotated left and right to avoid cutting the wound caused by violent pulling. Second, if the patient uses the absorbable thread intradermal suture method, cut the thread on one side of the incision and slowly pull out the silk thread on the other side of the incision when removing the thread. If there is resistance during the pulling process, the direction of the thread needs to be adjusted to avoid violent pulling causing the thread knot to remain in the incision. Third, for incisions closed by skin sutures, a special staple remover is required for removing the sutures, which can be removed more quickly.
