Surgical suture material with an antimicrobial surface and process for providing an antimicrobial coating on surgical suture material

Abstract

A surgical suture material with an antimicrobial surface is described, the surface exhibiting a coating containing a) at least one fatty acid, b) octenidine dichloride and / or dequalinium chloride and c) optionally oligomeric lactic acid esters. In addition, a process for coating surgical suture material is described which is characterized by the fact that the thread material is wetted with a homogeneous methanolic solution of octenidine dichloride and / or dequalinium chloride and subsequently the methanol is evaporated, a coating forming on the thread surface.

Description

technical field [0001] The subject matter of the present invention consists of two parts, a surgical suture material with an antimicrobial coating and a method for providing an antimicrobial coating on a surgical suture material. Background technique [0002] Based on the structure of surgical suture materials, they can be divided into monofilament and multifilament. Multifilaments can exhibit the so-called wicking effect. This refers to the migration of interstitial fluid along the filaments by capillary action. Microorganisms may also migrate with them, allowing the infection to spread along the filamentous material. Therefore, it is desirable to provide a finishing layer on surgical suture materials so that microorganisms are immobilized on the surface of the silk, thereby effectively preventing the migration of microorganisms along the silk. [0003] Braided polyglycolide multifilaments are of particular practical importance for absorbable suture materials. So far, o...
