A type of suturing method that directly brings the two sides of the incision wound edge together, such as skin suturing.

(1) Simple interrupted suture

It is simple to operate and has the most applications. Each stitch is knotted separately. It is mostly used for suturing skin, subcutaneous tissue, muscles, and aponeurosis, especially Suitable for suturing infected wounds.

(2) Continuous suture method

Tie a knot after the first stitch, and then use this suture to sew the entire wound. End the previous stitch and pull out the heavy thread tail. Stay on the opposite side and form a double line with a heavy knot at the end.

(3) Continuous seam suture method

It saves time in operation and has good hemostatic effect. The threads are staggered each time during the suturing process. It is mostly used for closing the broken ends of the gastrointestinal tract and skin transplantation. time stitching.

(4), Figure-8 suture

It consists of two interrupted sutures, which are firm and time-saving, such as fascial sutures.

(5) Penetrating suture method

Also known as suture ligation or suture hemostasis method, this method is mostly used to clamp a large number of tissues, where simple ligation is difficult or thread knotting is easy When falling off. Turn the tissue at the wound edge inward and keep the outside smooth. Such as gastrointestinal anastomosis and bladder suturing.

(1) Interrupted vertical mattress inversion suture method: also known as Lembert suture method, which is often used to suture the seromuscular layer during gastrointestinal anastomosis.

(2) Interrupted horizontal mattress inversion suture method: also known as Halsted suture method, mostly used for suturing the seromuscular layer of the gastrointestinal tract.

(3) Continuous horizontal mattress seromuscular inversion suture: also known as Cushing suture, such as gastrointestinal seromuscular suture.

(4) Continuous full-thickness horizontal mattress inversion suture method: also known as Connells suture method, such as full-thickness suture of gastrointestinal tract.

(5) Purse-bag suture method: Continuously suture the tissue surface in a circular shape for a week. When ligating, turn the center inward and bury it. The surface is smooth, which is conducive to healing. It is often used to close small incisions or needle holes in the gastrointestinal tract, embed the appendix stump, and fix fistula tubes in organs, etc.

(6) Half-purchase suture method: often used for embedding and inversion of the residual corner of the duodenum and gastric stump. The wound edge is everted, and the inner surface of the cavity to be sutured or anastomosed remains smooth, such as the suturing or anastomosis of blood vessels.

(1) Interrupted vertical mattress eversion suture method: such as suturing loose skin.

(2) Interrupted horizontal mattress eversion suture method: such as skin suturing.

(3) Continuous horizontal mattress eversion suture method: mostly used for anastomosis of blood vessel walls. It can be divided into two types: intradermal interrupted and intradermal continuous suturing. Intradermal suturing should use a small triangular ophthalmic needle, small needle-holding forceps and No. 0 silk thread. Suture essentials: Insert the needle from one end of the incision, then alternately pass through the skin at the edges of the incision on both sides, sew until the other end of the incision comes out, and finally tighten it. The two ends can be used as bow ties or gauze ball pads. It is often used for suturing exposed skin incisions, such as thyroid surgery incisions in the neck.

The quality of the suturing is related to the density and layering of the subcutaneous tissue suturing. If the incision tension is high and the subcutaneous sutures are not aligned properly, this method should not be used. The advantages of this suture method are good alignment, early suture removal, small healing scars, and beautiful appearance.

With the continuous development of science and technology, in addition to suturing, there are other methods of closing wounds, such as staplers, sealers, medical adhesives, skin zippers, etc.
