Designed by the United States Pharmacopeia (USP), the USP 881 standard is an industry standard referenced for testing the tensile strength of surgical sutures.
Testing the tensile strength of surgical sutures is a critical performance measure for determining the likelihood of a suture breaking. Precise, consistent and reliable power measurements are required for product development and quality control. The US Pharmacopoeia (USP) defines test requirements for surgical sutures made from absorbable or non-absorbable synthetic or natural materials.
For this purpose, all necessary mechanical tests are carried out in advanced laboratories to demonstrate the suitability of surgical sutures. For this purpose, in addition to the USP 881 standard, the USP 861 Suture diameter and USP 871 Needle attachment standards developed by the US Pharmacopoeia are also applied.
Surgical sutures are frequently used for a wide variety of purposes in skin surgery. The basic mechanical properties of suture materials are important for general stitch function and proper stitch selection. In these tests, surgical suture materials are expected not to break unexpectedly during use, not to cause wound edema, to be biocompatible, to be easily handled, to form a secure knot, and not to biodegrade in a suitable time period when used internally.
Knowledge of the tensile mechanical properties of various surgical suture materials allows to evaluate these properties. The most important of the commonly cited mechanical properties of surgical sutures are their basic tensile properties. Research into the various tensile behavior of surgical sutures generally focuses on breaking force.
Sutures have an important function to hold body tissues together during the healing process. The success of these yarns is generally evaluated by their tensile and knot strength performance.
Testing under the USP 881 standard uses a motorized tensile strength testing machine with appropriate clamps to hold the specimen firmly. In these tests, the tensile strength of the surgical suture is determined using the principle of constant load ratio on the specimen or the principle of constant extension ratio of the specimen.
Our organization also provides tensile strength testing services of surgical sutures within the scope of USP 881 standard, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
