Abstract

Wound closure is surgical aids relies heavily on sutures, which help maintain proper tissue alignment and supporting healing. The effectiveness depends on factor such as the type of wound, required mechanical strength, risk of infection and characteristics like absorbability and thickness of the martial. The efficacy of sutures is determined by their material properties and structural characteristic’s, which affect their mechanical properties. The primary objective of this study was to create absorbable medical sutures using a biocompatible polymer known as polylactic acid (PLA). The surgical suture made from polylactic acid (PLA) can be absorbed by human body. Furthermore, a composite suture consisting of PLA – chitosan was also developed to better performance. The suture was created through the extrusion method and followed by the stretching process to enhance their strength and structure.  In recent year, synthetic polymer such as polylactic acid (PLA) have gained significant attention due to their controlled biodegradability and improved mechanical performance. The PLA sutures were successfully produced, and their performance was improved by applying a chitosan. The prepared sutures demonstrated good flexibility, with the capacity to stretch before breaking, and showed a crystallinity that is contribute to their strength and stability. They also exhibited better knotting and trying ability, which is very important part during surgical procedure.

Keywords: polylactic acid (PLA), Sutures, chitosan, biocompatible polymer.
