The WY-019 Surgical Blade Sharpness Tester is a professional precision detection device independently developed for the sharpness performance testing of surgical blades, strictly complying with the requirements of the YY 0174-2019 national industry standard for medical devices. It is specially designed to solve the pain points of low testing efficiency, poor data accuracy and lack of standardized operation in the traditional manual sharpness testing of surgical blades, and provides reliable technical support for medical device manufacturers, quality inspection and supervision institutions, and scientific research laboratories.

In terms of core testing principles, the equipment adopts a vertical cutting test method, which is highly consistent with the actual clinical use scenario of surgical blades. It is equipped with an imported high-precision force sensor with a measurement range of 0-15N and a resolution of 0.001N, which can capture the subtle changes of cutting force in real time during the test process. The test platform is driven by a servo motor, which ensures that the cutting speed is kept at a constant value set by the standard, avoiding the error of test results caused by unstable speed in manual operation. During the test, the standard suture is fixed on the dedicated fixture, and the surgical blade to be tested is installed on the cutting slide. The device drives the blade to vertically cut the suture at a constant speed, and the sensor transmits the collected force data to the control system synchronously, realizing the accurate quantification of the blade sharpness.

The equipment has a humanized operation design, with a 7-inch high-definition touch screen as the man-machine interaction interface, and the operation interface is simple and intuitive. Operators can complete the whole process of parameter setting, test start, data viewing and report printing only by simple touch operation, without professional programming foundation. The system supports one-key test function. After the test parameters such as cutting speed and test times are set, the equipment can automatically complete the test operation, and automatically record the peak cutting force, average force and other key data of each test. At the same time, the device can generate and display the real-time force value curve during the cutting process, which is convenient for testers to analyze the sharpness change law of the blade in the cutting process.

In terms of compatibility and scalability, the WY-019 Surgical Blade Sharpness Tester has strong versatility, and can be compatible with various specifications of surgical blades commonly used in clinical practice by replacing dedicated fixtures. The fixture adopts a quick-release design, which can be disassembled and replaced in 30 seconds, greatly improving the test efficiency of multi-specification blade batch testing. In addition, the equipment is equipped with a built-in data storage module, which can store up to 10,000 sets of test data. The stored data can be queried and exported at any time through the U disk interface, which is convenient for testers to carry out data statistics and analysis. The device also has a built-in thermal printer, which can print the test report on site, including test date, blade model, test data, compliance judgment and other information, meeting the needs of quality inspection and supervision for traceable test data.

In terms of safety and stability, the equipment is designed with multiple safety protection functions. The test area is equipped with a transparent safety cover. When the cover is not closed, the equipment cannot start the test, which effectively prevents the operator from being injured by the blade during the test. The whole machine is made of high-strength aluminum alloy and stainless steel, with good corrosion resistance and structural stability, which can adapt to the long-term continuous operation in the laboratory environment. The equipment has passed strict factory calibration and performance testing, and the test data has high repeatability and accuracy, with the test error controlled within ±0.5%, ensuring the reliability of the test results.

As a professional surgical blade sharpness testing equipment, the WY-019 is not only an important tool for medical device manufacturers to control product quality, but also an essential detection instrument for quality inspection institutions to carry out supervision and sampling inspection work. It can effectively help users improve the testing efficiency of surgical blade sharpness, reduce the labor cost of testing, and ensure that the surgical blades put into clinical use meet the safety and performance requirements, thus providing a strong guarantee for the safety of clinical surgery.
