This saves time, and eliminates the most difficult threading of very fine needles and sutures. Two additional benefits are reduced drag and less potential damage to friable tissue during suturing. In a swaged suture the thread is of narrower diameter than the needle, whereas it protrudes on both sides in an eyed needle.
Adsorbable biological suture material. Chromic is an adsorbable suture made by twisting together strands of purified collagen taken from bovine intestines. Due to undergoing a ribbon stage chromicisation (treatment with chromic acid salts), the chromic offers roughly twice the stitch-holding time of plain catgut.
Certainly modern synthetic sutures are more predictable and less prone to infection than catgut, silk and linen, which were the main suture materials used up to the 1990s. One key feature of intestinal staplers is that the edges of the stapler act as a haemostat, compressing the edges of the wound and closing blood vessels during the stapling ...
Surgical suture on needle holders. Catgut suture in a vintage glass dispenser. Catgut suture is a type of surgical suture made of twisted strands of purified collagen taken from the small intestine of domesticated ruminants or beef tendon. It is naturally degraded by the body's own proteolytic enzymes.
Stronger braided suturing thread is preferred because the knot has a tendency to fray as it is slid down the cannula. At the end of the running suture line, clips can be placed across the suture tail. Barbed suture is a knotless surgical suture that has a pattern of barbs on its surface. These barbs lock the suture into the tissue, eliminating ...
The vertical mattress stitch is most commonly used in anatomic locations which tend to invert, such as the posterior aspect of the neck, and sites of greater skin laxity such as the closure of lax skin after removing a dermoid cyst or reduced subcutaneous tissue (e.g., the shin) that do not provide adequate subcutaneous tissue for dermal closure.

In anatomy, a suture is a fairly rigid joint between two or more hard elements of an organism, with or without significant overlap of the elements. [ 1 ] Sutures are found in the skeletons or exoskeletons of a wide range of animals, in both invertebrates and vertebrates .
The two most important qualities for skin sutures are (1) that the wound not re-open before it is healed and (2) that the scar be as thin and subtle as possible. One of the advantages of removable sutures is that the time of removal is controlled-- the doctor can specify exactly when to remove them.
