Who invented catgut suture?
His real name was Abu al-Qasim Khalaf Ibn Al-Abbas Al-Zahrawi and he is also known as Albucasis (1, 2). He received education in Córdoba University which was rich in science and culture.
What type of suture is catgut?
Catgut is extracted from the intestines of sheep or goats. There are two types used for sutures: plain and chromic. Both are monofilament type. Chromic is treated with chrome salts (brown color) which slows the absorption process in the body and minimizes the tissue reaction in surrounding tissues.
How long do catgut stitches last?
A material that’s commonly used for dissolvable stitches in orthopedic surgeries, like knee surgery, is polydioxanone. These stitches can take about six months to completely dissolve.
What is catgut suture used for?
The main indications for use of catgut suture include ligation of superficial vessels and closure of tissues that heal rapidly, such as oral mucosa. Catgut sutures also can be used in situations where one wishes to avoid suture removal, as in small children.
What are strings made of now?
Today, violin strings are comprised of a string core wrapped with wound metal. The core can be made of gut, steel, or synthetic polymers.
What is chromic catgut?
Chromic catgut is a modification of plain catgut that is tanned with chromic salts to improve strength and delay dissolution. 29. Gut is absorbed by phagocytosis, and is associated with a marked tissue inflammation that can be detrimental to healing.
What material is used for stitches?
A doctor uses a piece of surgical thread called a suture to sew (or stitch) two ends of skin together. Surgeons once used animal tendons, horsehair, pieces of plants, or human hair to create sutures. Today, they’re made from natural or manmade materials like plastic, nylon, or silk.
Which is the most important characteristic of chromic catgut sutures?
Chromic is treated with chrome salts (brown color) which slows the absorption process in the body and minimizes the tissue reaction in surrounding tissues. Some unique characteristics of catgut include its uniformly finegrained tissue structure and a high elasticity and tensile strength.
What is the most common suture?
Simple interrupted suture: It is the most common and simple form of suturing technique. The suture is placed by inserting the needle perpendicular to the epidermis. Inserting it perpendicularly helps in a wider bite of deeper tissue to be included in the suture than at the surface leading to rapid wound healing.
