At the time of surgery, especially for surgical procedures with large incisions, medical sutures have become one of the important tools for surgery. Although the wound suture after surgery is the basic skill of surgery, the importance of wound suturing cannot be ignored.
Why medical sutures are an important tool in surgery? What are the advantages of medical sutures? What are the benefits of medical sutures for patients? Why are medical sutures classified as absorbable sutures and non-absorbable sutures?
Medical sutures are sterile lines for surgical wound suturing, tissue ligation, and tissue fixation. Suturing the surgical wound is to shorten the healing time of the surgical wound, thereby reducing the infection of the surgical wound, and also plays a key role in shortening the course of the disease, reducing the scar of the wound and improving the appearance of the wound.
There are many kinds of medical sutures. If they are classified according to the structure of medical sutures, there are monofilament, multifilament, twisted, twisted and so on. If classified according to the biodegradability of medical sutures, it can be divided into absorbable sutures and non-absorbable sutures. Each type of suture plays a different role in different parts and conditions, so the choice of suture is also crucial.
Non-absorbable sutures have been used for a long time in clinical surgical wound sutures where natural and synthetic textile fibers are used to make surgical sutures. Cotton fiber is one of the earliest raw materials for making surgical sutures.
Absorbable sutures are used more and more widely in modern clinical surgery. The earliest absorbable sutures were made from collagen in the intestine mucosa and bovine intestinal mucosa. However, after the surgical wound was sutured, the body tissue responded more to the catgut, so now the catgut sutures are gradually Replaced by new surgical sutures, such as PGA, PGLA, PGCL, etc. However, the absorbable sutures have the disadvantage of being difficult to precisely control the absorption period, and relevant researchers are working hard to solve this problem.
What sutures can be a qualified medical sutures? What characteristics are needed to be used as surgical sutures for surgical wound sutures?
Medical sutures should have high strength, while retention in wounds or tissues that have been sutured should be kept in sync with the degree of healing. It should also have excellent handling, knotting, knot retention, good flexibility and flexibility. It also needs to have a certain degree of extensibility, can adapt to the characteristics of wound tissue edema, and can be restored to the original state after the wound is healed; the cross-sectional diameter of the medical surgical suture should be as small as possible to minimize or avoid tissue. The reaction also needs to be able to withstand and facilitate sterilization and other treatments.
For absorbable sutures, there should be some tissue adaptability. As the healing of the surgical wound can be completely absorbed by the body; for non-absorbable sutures, after the surgical wound is healed, the non-absorbable suture should be as free as possible.
