The following table compares some of the most common adsorbable sutures. Plain catgut. Chromic catgut. Polyglycolide. (P.G.A.) Polydioxanone (PDS) Description. Adsorbable biological suture material. Plain is an adsorbable suture made by twisting together strands of purified collagen taken from bovine intestines.
A surgical suture, also known as a stitch or stitches, is a medical device used to hold body tissues together and approximate wound edges after an injury or surgery. Application generally involves using a needle with an attached length of thread. There are numerous types of suture which differ by needle shape and size as well as thread material ...
Catgut Chrome (B Braun) suture is a variant treated with chromic acid salts. This treatment produces roughly twice the stitch-holding time of plain catgut, but greater tissue inflammation occurs. Full tensile strength is extended to 18–21 days. It is brown rather than straw-colored, and has improved smoothness due to the dry presentation of ...
Vicryl (polyglactin 910) is an absorbable, synthetic, usually braided suture, manufactured by Ethicon Inc., a subsidiary of Johnson and Johnson. A monofilament version is also made for use in ophthalmic practice. It is indicated for soft tissue approximation and ligation. The suture holds its tensile strength for approximately two to three ...
Guided bone and tissue regeneration (dentistry) Guided bone regeneration (GBR) and guided tissue regeneration (GTR) are dental surgical procedures that use barrier membranes to direct the growth of new bone and gingival tissue at sites with insufficient volumes or dimensions of bone or gingiva for proper function, esthetics or prosthetic ...
Chemically, polydioxanone is a polymer of multiple repeating ether - ester units. It is obtained by ring-opening polymerization of the monomer p -dioxanone. The process requires heat and an organometallic catalyst like zirconium acetylacetone or zinc L-lactate. It is characterized by a glass transition temperature in the range of −10 and 0 ...
Prolene is a brand of synthetic polypropylene used in monofilament nonabsorbable sutures and meshes. The suture is indicated for skin closure and general soft tissue approximation and ligation. Its advantages include minimal tissue reactivity and durability. Disadvantages include fragility, high plasticity, high expense, and difficulty of use ...
Surgical scissors are scissors specially manufactured as surgical instruments, typically used for cutting sutures, dressings, and cutting and dissecting biological tissue. [1][2] Surgical scissors are usually made of surgical steel. Some have tungsten carbide reinforcements along their cutting edges, the hardness of which allows manufacturers ...
