The catheter guide wire friction tester is a medical device mainly used to measure the friction between the catheter and the guide wire. This type of device is of great significance for research and practice in the medical field, as it can help doctors understand the motion characteristics of catheters and guide wires in the human body, thereby optimizing surgical operations and improving treatment outcomes.

In the medical field, catheters and guidewires are widely used in various surgical procedures, such as angiography, cardiac intervention surgery, nerve intervention surgery, etc. The smooth movement of the catheter and guide wire is crucial for the success of these surgeries. Therefore, the development and application of a catheter guide wire friction tester are of great significance for improving the safety and effectiveness of surgery.

By using a catheter guide wire friction tester, doctors can understand the changes in friction between the catheter and guide wire under different conditions, providing more accurate references for surgical operations. For example, during cardiac intervention surgery, doctors can select the most suitable catheter and guide wire for the patient's surgical needs by testing the friction between catheters and guide wires of different materials and diameters, thereby reducing surgical risks and improving treatment outcomes.

Testing principle:

The sample is clamped between the two clamps of the fixture, and the two clamps move relative to each other. A special clamp is used to perform a puncture or opening force test. The force value sensor located on the moving clamp and the displacement sensor built-in in the machine are used to collect the force and displacement changes during the test process, and the corresponding force value data is obtained.
