Standards
The detection standards of the Sharpness and Strength Tester for Suture Needles comply with the relevant regulations ofYY/T 0043 - 2016 *Medical Suture Needles*. This standard puts forward clear requirements for the edge sharpness of suture needles. That is, at a specific cutting speed, the cutting force of the edge shall not exceed a certain threshold. The tester is designed and manufactured based on this standard, aiming to provide a reliable quality - control tool for the medical industry.

Accessoriess
1. Core testing accessories: HRC≥60 standard test steel block, 9mm specification test mold, high-precision force sensor calibration component;
2. Sample fixing accessories: Adjustable positioning fixture suitable for 0.2-1.8mm suture needles, sample limit seat;
3. Auxiliary function accessories: Miniature dot matrix printing paper, equipment power adapter, dedicated cleaning tools;
4. Basic supporting accessories: Operation manual, calibration record form, spare connecting cables.
Test Procedures
1.Pre-operation Preparation
Check power supply (AC220V50Hz) and equipment connections; confirm steel block hardness, sensor probe integrity, and fixture no jamming; prepare suture needle samples (size 0.2-1.8mm, no deformation); ensure test environment is dry and clean.
2.Parameter Setting
Power on, select Chinese/English interface, enter PLC control system; set test mode (sharpness/puncture force/strength), loading rate (≤10mm/s), and sample specification.
3.Sample Installation
Fix suture needle on adjustable fixture, adjust positioning tooling to align needle tip with standard steel block and sensor probe.
4.Test Execution
Confirm sample fixation, start test; equipment automatically loads and detects data, dynamically displays force value; stop immediately if abnormal data appears.
5.Post-test Handling
After test, take out sample, print data via dot-matrix printer; clean fixture, steel block and test table with cleaning tools; power off and store equipment.
