Test Procedures

— Secure the sample (blade) in the fixture;

— Fix one end of the suture to a winding clamp, and attach a 100 g weight to the other end of the suture, ensuring the suture is horizontal, and fix it to another winding clamp;

The sample is moved vertically downwards at a speed of no more than 10 mm/s to cut the middle part of the suture;

When the suture is cut, the instrument's indicator shows the force exerted by the blade to cut the suture.

Each blade should be tested at three points: the front, middle, and back of the cutting edge, and the arithmetic mean should be taken.

FAQ

1. What is the main purpose of the Surgical Blade Sharpness Tester?

The Surgical Blade Sharpness Tester is designed to evaluate the sharpness performance of various blades, including surgical blades and utility knife blades. By simulating the actual cutting process and measuring the force required for a blade to cut through standard test materials such as suture lines, the instrument determines whether blade sharpness meets relevant standard requirements. It provides accurate and reliable data to support quality control, product selection, research and development, and teaching applications involving cutting tools.

2. How is the Surgical Blade Sharpness Tester used in medical device manufacturing quality control?

In medical device manufacturing, the Surgical Blade Sharpness Tester is used to conduct quality inspections on surgical blades before they enter the market. The device simulates surgical cutting conditions and measures the cutting force required to sever standardized suture materials. By comparing test results with standard requirements, manufacturers can determine whether blade sharpness is qualified. Only blades that pass sharpness testing are released, helping ensure the safety, consistency, and reliability of surgical instruments and supporting smooth surgical procedures.

3. What types of blades can be tested with this instrument?

The tester is capable of evaluating a wide range of blade types and specifications. According to the technical parameters, it can test straight blades, circular blades, and angled ophthalmic blades, covering common surgical blade designs.
