1. Catgut: It is made from healthy animal goat intestines and contains collagen, so there is no need to remove the suture after suture. Medical catgut is

divided into: ordinary catgut and chrome catgut, both of which can be absorbed. The length of time required for absorption depends on the thickness of

the gut and the condition of the tissue. Generally, it can be absorbed in 6 to 20 days, but individual differences in patients affect the absorption process,

and even no absorption. The intestines are all single-use sterile packaging, which is easy to use.

2. Chemical synthesis line (PGA, PGLA, PLA): a polymer linear material made with current chemical technology, made by thread drawing, coating and

other processes, generally absorbed within 60-90 days, and the absorption is stable. If it is due to the production process, there are other

non-degradable chemical components, the absorption is incomplete. Non-absorbable thread

That is, the suture cannot be absorbed by the tissue, so the suture needs to be removed after the suture. The specific stitch removal time varies

depending on the suture location, the wound, and the patient's condition.
