SUTURING SKINSUTURES MUCUS MEMBRANE DEEP WITH FACIA, FAT & SKIN MUSCLES BLEEDING FROM VESSELS
SUTURINGThere are several shapes of surgical needles: Straight 1/4 circle 3/8 circle 1/2 circle. Subtypes of this needle shape include, from larger to smaller size, CT, CT-1, CT-2 and CT-3. 5/8 circle compound curve half curved (also known as ski) half curved at both ends of a straight segment (also known as canoe)
SUTURING Needles may also be classified by their point geometry; examples include: taper (needle body is round and tapers smoothly to a point) cutting (needle body is triangular and has a sharpened cutting edge on the inside curve) reverse cutting (cutting edge on the outside) trocar point or tapercut (needle body is round and tapered, but ends in a small triangular cutting point) blunt points for sewing friable tissues side cutting or spatula points (flat on top and bottom with a cutting edge along the front to one side) for eye surgery
Suture Material Types of sutures : Absorbable sutures such as plain,chromic, a traumatic catgut. Non absorbable or non absorbent sutures.
Reading the Suture Label Order Code Size Also: Name LENGTH NEEDLE SYMBOL Needle COLOR Absorbable or Non Company
Suture Material ABSORBABLE SUTURES: CATGUT A tough thin cord made from the treated and stretched intestines of certain animals, especially sheep. This type of suture are commonly used to suture the inner structure of the body Walls of the organs Rectal sheath Muscles Subcutaneous tissue Peritoneum Intestinal anastomosis
Suture Material 1) Plain catgut : These sutures are completely digested & absorbed by the tissue. Sizes of the absorbable catgut suture vary from 5/0 which is the finest to 2 which is the thickest.
Suture Material Chromic catgut : Chromic catgut an absorbable sterile strand derived from the intestinal submucosa of sheep. It is an absorbable suture The chromic catgut is of brown color & is absorbed slowly
Suture Material Atraumatic catgut It is another type which is used for ligating small blood vessels. Dexon (Polyglycolic acid) is also an absorbable suture synthetically prepared. It is available in various sizes such as 3/0 to 2. This suture is used as ties for small blood vessels & also for suturing peritoneum ,rectal sheath etc.
Non absorbable sutures These types of sutures are not absorbed. These sutures are used for closing or suturing outer surface of the body such as skin. These sutures are cheaper, easy to handle easy to sterile ,have smooth surfaces & knot securely with the ends cut short.
Suture Material Silk suture : these suture are non absorbent. Their sizes vary from 10/0 to 2 . These are used for skin closure after abdominal operation. Linen suture : these sutures are also non absorbent .their sizes vary form 3/0 to 2 . These are used for skin closure in hernia operation. Monofilament Nylon suture ( Ethilon) : These are non absorbable suture. Their sizes vary from 10/0 to 2. these sutures are used as tension sutures in hernia repair.
Suture Material e) Prolene –Ethifex merseline : These non absorbent sutures are used for cardiovascular & plastic surgery. f) Metal Clips : these non absorbent types of suture are of various types such as : Michael clips Trazies Van petz VICRYL (polyelatine– 916) PROLENE (Polypropylene) POLYSTER (ethibond) POLYDIXONE SUTURE
Superglues that contain acrylates Tissue adhesive may be applied to superficial wounds to block pinpoint skin hemorrhages and to precisely coat wound edges. Because of their bacteriostatic effects and easy application, they have gained increasing popularity. They have demonstrated either cosmetic equivalence or superiority to traditional sutures in various procedures, including sutureless closure of pediatric day surgeries, saphenous vein harvesting for coronary artery bypass, and blepharoplasty.
