AI Technical Summary
Existing medical scalpel testing devices cannot easily adjust the position of the fishing line or suture, which requires frequent disassembly and reassembly of the medical scalpel when testing the sharpness of different locations, resulting in low testing efficiency.
The gear system, driven by an electric push rod and a geared motor, adjusts the forward and backward movement of the fishing line through the engagement of gears and meshing grooves. Combined with a pressure sensor to detect the sharpness at different positions, it simplifies the tool position adjustment process.
It enables efficient detection of the sharpness of medical cutting tools at different locations, improving detection efficiency, reducing the number of tool disassembly and assembly operations, and enhancing operational convenience.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cutting tool testing technology, and in particular relates to a medical cutting tool testing device. Background Technology
[0002] Medical surgical instruments are commonly used in hospitals, including various types such as scalpels and cutting blades, and mainly consist of a blade and a handle. These instruments are designed for precise cutting, trimming, and removal of tissue, requiring extremely high sharpness and durability, and are typically made of stainless steel or other alloy materials. To ensure the sharpness of medical instruments, testing devices are used to assess their sharpness.
[0003] For example, the prior art patent announcement number CN215767618U discloses a medical knife sharpness tester. This utility model installs one end of a fishing line or suture on a clamp, and the other end passes through the first guide hole on the first connecting rod and around the guide wheel before being tightened by weights. The knife is clamped on the knife clamping device, and the knife is driven upward by a drive device. The blade of the knife contacts the fishing line or suture until it cuts the thread, and the cutting force is detected by a pressure sensor, thereby inferring the sharpness of the knife. This detection method is more accurate and suitable for testing medical knives.
[0004] The aforementioned patent uses a wire mounting device to test the fishing line or suture of a medical cutting tool. However, the wire mounting device is not convenient for adjusting the front and back positions, meaning the front and back positions of the fishing line or suture cannot be adjusted. Since the blade of a medical cutting tool has a certain length, when it is necessary to test the sharpness of different positions of the medical cutting tool, the fixed medical cutting tool needs to be removed, its position adjusted, and then tested. This operation is cumbersome and the testing efficiency of medical cutting tools is low. Therefore, we propose a medical cutting tool testing device. Utility Model Content
