Catgut, a different protein fibre with a biological origin, is produced in animals’ lower intestines, usually those of sheep and oxen. The digestive tracts of calves are treated using chromic salt solutions to create Catgut after being mechanically and chemically stripped of soft tissues and other leftovers. The ribbons are obtained in large quantities and twisted into linked strands. Then, using an appropriate technique, the chromic salts are removed. Since Catgut stiffens when it dries and thus complicates handling items created from it, chromic Catgut is often maintained in watery alcohol and glycerine to keep it from drying out.
For approximately 20 days, chromic Catgut may keep its tensile strength. Compared to normal catguts, chromic catguts have a lower risk of inflammatory and foreign object responses because foreign proteins aren’t immediately exposed. Sutures made of ordinary gut & chromic gut are made of many flanges that have been gently twisted, machines ground, & polished to produce a surface that resembles monofilament.
It is a simple surgical gut suture formed by twisting together strands of collagen fibres material removed from the submucosal sections of healthy sheep or goat small bowel. Chromic Catgut Suture is a twisting multifilament arrangement with such a monofilament look. Chromic Catgut is treated using chromic salts to prevent absorption & processed to increase resistance towards absorption. Chromic sutures are sterile and only slightly cause tissue response when absorbed.
The best needles with the sharpest points are produced in-house, resulting in sutures that glide smoothly across the tissue. Chromic Catgut is a naturally easily absorbed surgical suture that absorbs through a simple enzymatic process. However, absorption is less predictable with Chromic Catgut than it is with synthetic sutures. Chromic catgut absorbable sutures often absorb more quickly in harmed tissues. The early tensile strength of unique sutures is diminished between 14 and 21 days and absorbed by 90 – 120 days. It is physiologically inert & non-adhering.
To maintain their elasticity, catgut sutures were packed in alcohol solutions (ethanol and isopropanol), and the containers were sterilized, whether using co-gamma irradiation or ethylene oxide. Alcohol is not required for packing chromic Catgut, which also has better handling properties. Compared to untreated Catgut, the overall surfaces of the solvent sutures are smooth and so more uniform, and the suture was thicker as a consequence of the glycerine treatments.
Catgut Chromatic Sutures’ Characteristics
• Sutures made of Catgut are organically absorbable.
• Catgut Chromic Sutures have chromic salt applied to them, giving them a bright brown colour.
• CCS come in sizes ranging from USP 2 to 4-0.
• To create catgut sutures, the intestinal submucosa of goats & sheep is longitudinally sliced, and then the sutures are twisted and polished until they resemble monofilaments.
• Chromic Catgut Sutures soak via a straightforward enzymatic hydrolytic process, and absorption becomes less consistent than synthetic sutures. Infectious tissues often absorb catgut sutures more quickly.
• After 21 to 28 days post-implantation, Catgut Chromic Suture preserves around 50% of its original tensile strength, which is dissolved mainly after 90 days.
Catgut works best on wounds in places where tissue heals quickly. In general, chromic Catgut tends to trigger a more acute tissue response.
