SUTURE MATERIAL CAN BE:
Atraumatic
Traumatic

Слайд 3

CLASSIFICATION OF SUTURE MATERIAL
1. By historical feature:
1. Traditional suture materials:

catgut (animal gut), silk, horsehair, cotton
2. Synthetic suture materials: Polyglycolic acid(PGA), polylactide, polyamide, polyester, polypropylene, PVDF
2. By structure:
1. Monofilament (пролен, ПДС, этилон, нейлон, суржипро, максон и тд)
2. Multifilament
Twisted (silk, caprone)
Braided (lavsan, mercilene, etibond)
Coated or pseudo-monofilament (vicryl, polysorb, supramide)

CLASSIFICATION OF SUTURE MATERIAL
3. By the ability to absorption (biodestruction):
Absorbable —

catgut, vicryl, polysorb, дексон, monocryl, PDS.
Pseudo-absorbable – silk, caprone.
Non- absorbable —etibond, lavsan, prolene, surgipro, polypropilene, stainless steel wire.
4. By starting materials:
Natural starting organic materials - (catgut (animal gut), silk, horsehair, threads made of fascias, tendons, peritoneum).
Natural starting mineral materials - (stainless steel wire).
Synthetic materials(polyesters, polyolefins, fluoropolymers): vicryl, PDS, PGA, monocryl, maxon, etibond, lavsan etc.

REQUIREMENTS TO “IDEAL” SUTURE MATERIAL
1. Biocompatibility (no tissue reaction);
2. No sawing

action;
3. No wicking;
4. Flexibility, thread ca be easily knotted;
5. High tensile strength;
6. High knot security;
7. Absorption ability;
8. Universatility;
9. Sterility.
10. Price accessibility.
