Chapter 1575-sharing

Catgut was a commonly used medical suture, mainly used for suturing wounds that were difficult to remove. With the development of times, the source was no longer limited to sheep's intestines. However, before catgut was used on a large scale, it was popular to use the tail tendon of a mouse to make the suture.

Compared to sheep intestines, rat tail tendons had many advantages. The main one was that it was easier to raise rats than sheep. Moreover, the human body absorbed rat tail tendons better and had almost no rejection reaction. The disadvantage was that rat tails were short and thin, and the length of the tail tendons was not long enough.
