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 ...
Catgut (also known as gut) is a type of cord [1] that is prepared from the natural fiber found in the walls of animal intestines. [2] Catgut makers usually use sheep or goat intestines, but occasionally use the intestines of cattle, [3] hogs, horses, mules, or donkeys. [4] Despite the name, catgut is not made from cat intestines.
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.
Today, most sutures are made of synthetic polymer fibers. Silk and, rarely, gut sutures are the only materials still in use from ancient times. In fact, gut sutures have been banned in Europe and Japan owing to concerns regarding bovine spongiform encephalopathy. Silk suture is still used today, mainly to secure surgical drains. [31]
Although catgut is still prized by many musicians today, due to its unique sound. [3] The invention of wound strings (particularly steel) was a crucial step in string instrument technology, because a metal-wound string can produce a lower pitch than a plain gut string of similar thickness.
He pioneered the use of catgut for internal stitches, and his surgical instruments are still used today to treat people. He was the first physician to identify the hereditary nature of haemophilia and describe an abdominal pregnancy , a subtype of ectopic pregnancy that in those days was a fatal affliction, and was first to discover the root ...
Some instrumentalists, however, still use gut strings in order to evoke the older tone quality. Although such strings were commonly referred to as "catgut" strings, cats were never used as a source for gut strings. [53] Sheep gut was the original source for natural gut string used in racquets, such as for tennis.
Violin strings were originally made from catgut, which is still available and used by some professional musicians, [32] although strings made of other materials are less expensive to make and are not as sensitive to temperature. [31] Modern strings are made of steel-core, stranded steel-core, or a synthetic material such as Perlon. [31]
