Applications:

Quality Control for Manufacturing Enterprises: During the production of suture needles, the tester can conduct sampling tests on each batch of suture needles, promptly identifying quality issues in the production process, such as unstable raw material quality or defects in processing techniques. This enables timely adjustment of the production process to ensure the stability and consistency of product quality. Selecting Appropriate Suture Needles for Medical Institutions: Medical institutions can use the tester to conduct performance tests on different types of suture needles, and based on the test results, select the suture needles that best meet the surgical needs of patients, thereby improving surgical effectiveness and patient safety. Product R & D and Optimization: R & D personnel in the medical device field can use the tester to evaluate the performance of the design of new - type suture needles. By testing the strength and puncture force of suture needles with different structures, materials, and dimensions, they can optimize the design of suture needles and develop products with better performance.

Product Information:

The Suture Needle Elasticity and Toughness Tester is designed for evaluating the physical performance of medical suture needles, specifically their elasticity and toughness. It is an important testing instrument for determining the quality of suture needle products.

Test Principle

Toughness Test:

A specified force is applied to the center of the suture needle to bend it. For straight needles, the needle is bent to 90°; for 1/2 arc needles, it is bent to 3/8 arc; and for 3/8 arc needles, it is bent toward a straight line. The downward displacement is calculated, and whether the needle breaks is used to determine whether it passes or fails the test.

Elasticity Test:

A specified force is applied to the center of the suture needle to cause elastic deformation and increase its chord length to a preset value. The force is then gradually removed, and the change in chord length is measured. The elastic deformation and recovery deformation are calculated using a dedicated non-contact displacement measurement mechanism.
