Suture Needle Penetration and Bending Strength Tester

The Suture Needle Puncture and Bending Strength Tester has broad application prospects and significant application value in the medical device industry. The following is a detailed introduction to its main uses, compliance standards, and technical parameters:

一、Main Uses

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.

二、Compliance Standards

The Suture Needle Puncture and Bending Strength Tester complies with relevant standards such as ASTM F3014 - 2014 and ASTM F1874 - 98. - ASTM F3014 - 2014: Specifies the specific methods and procedures for the penetration test of surgical suture needles, aiming to evaluate the penetration performance of suture needles to ensure they can meet requirements in actual use. - ASTM F1874 - 98: Specifies the specific methods and procedures for the bending test of surgical suture needles, aiming to evaluate the strength and durability of suture needles under bending conditions.

三、Technical Parameters

Testing Items: Puncture force, bending strength. Range: Usually can be customized according to actual needs, such as 0 - 50N. Stations: Designed with multiple stations, which can be adjusted according to test requirements, such as 12 stations. Accuracy: High - precision sensor, with an indication error usually not exceeding 0.01N or 0.1%FS. (full - scale range). Needle - clamping Fixture: Fixtures for holding suture needles, such as 4°±2°/s, etc., to ensure the stability and accuracy of suture needles during the testing process. Speed: The testing speed can be adjusted according to actual needs. For example, the minimum speed is 10cm/min (4in./min), and the maximum speed is 30.5cm/min (12in./min), etc.

Testing Rate: The speed when loading to the set value usually does not exceed 10mm/s. Power Supply: Usually 220V 50Hz or other voltages and frequencies that comply with local electrical standards.
