Medical Suture Line Diameter Tester

The Medical Suture Thread Diameter Tester is a specialized testing equipment used for measuring the diameter or linear diameter of medical suture threads. The following is a detailed introduction to its main uses, compliance standards, and technical parameters:

一、Main Uses

Quality Control: The medical suture thread diameter tester plays a crucial role in the quality control of medical devices. By accurately measuring the diameter of suture threads, it ensures that products meet relevant medical standards and specification requirements, thereby improving the quality and safety of medical devices. Manufacturer Inspection: During the production process, manufacturers need to conduct strict quality inspections on each batch of suture threads. The thread diameter tester can monitor the changes in thread diameter in real - time, promptly detect and correct production deviations, and improve production efficiency and product quality. Third - Party Inspection: Independent third - party testing laboratories are responsible for conducting random quality inspections and verifications on suture threads sold in the market. The high - precision data provided by the thread diameter tester can serve as a reliable basis for test reports, ensuring the safety and effectiveness of products during use. Product R & D: In the process of developing new suture thread products, R & D personnel need to repeatedly verify and adjust product specifications. The thread diameter tester can provide accurate thread diameter measurement data, helping R & D personnel optimize the design and improve product performance.

二、Compliance Standards

The medical suture thread diameter tester needs to comply with relevant medical industry standards, such as YY 1116 - 2020 Absorbable Surgical Suture and YY 0167 - 2020 Non - absorbable Surgical Suture. These standards specify in detail the requirements for the technical parameters, testing methods, and measurement accuracy of the suture thread diameter tester, ensuring the accuracy and reliability of measurement results.

三、Technical Parameters

The technical parameters of the medical suture thread diameter tester usually include the following aspects: Minimum Division Value: The minimum division value of the tester usually does not exceed 0.002mm, and some high - precision devices can even reach 0.001mm to ensure precise measurement of the suture thread diameter. Base Diameter: The base diameter is usually greater than 50mm, providing a stable basic support for measurement. Pressing Plate Diameter: The diameter of the pressing plate is usually 12.70mm±0.02mm, used to apply pressure to the suture thread for measuring the thread diameter. Presser Foot Load: The load of the presser foot (including the pressing plate) varies according to the specifications of the suture thread. Generally speaking, for suture threads with specifications larger than a certain size (such as nominal size 0.4 or 8 - 0), the presser foot load is 210g±3g; for suture threads with specifications less than or equal to this size, the presser foot load should be ≤60g. Calibration Difference and Parallelism Difference: The calibration difference and parallelism difference between the surface of the pressing plate and the base should not be greater than 0.005mm to ensure the accuracy of measurement.
