Suture Needle Sharpness Intensity Tester
The Sharpness and Strength Tester for Suture Needles is a device specifically designed to detect the sharpness and strength of medical suture needles.
Applications
Assessing Penetration Performance: By simulating the process of suture needles penetrating the skin or other media, measure the required puncture force, and thus evaluate the penetration performance of suture needles. This is crucial for ensuring the smooth use of suture needles in actual medical operations.
Quality Control: Used to detect the sharpness and strength of the tips of medical suture needles, ensuring that products meet relevant standards and regulations. It can promptly identify and eliminate non - compliant products, guaranteeing product quality. Procurement Decision - making: Helps medical institutions compare and select when purchasing suture needles, ensuring that the purchased suture needles have appropriate sharpness and strength to meet surgical needs. R & D Support: During the R & D process of medical suture needles, it provides key data support, helping researchers understand the impact of different materials, designs, and processes on the sharpness and strength of suture needles, so as to optimize product performance.
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.

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.
