The earliest record of surgical suture can be traced back to ancient Egypt in 3000 BC, and the oldest known suture is on the mummy in 1 100 BC. The first detailed written record about wound suture and the use of suture materials came from Suxuruta, a saint and doctor in India in 500 BC. Hippocrates, the "father of medicine" in Greece, and Celsus in Rome later described the basic suture technique. Intestinal suture was first described by Roman doctor Galen in the 2nd century, and some people thought it was Zahrawi, an Andalusian surgeon in the10th century. According to records, zahra Velluti's string was once swallowed by a monkey, and he discovered the absorbability of gut. Since then, medical catgut has been made.
