Description

Bolt taking support recovery force test fixture Technical Field The utility model belongs to the technical field of thrombus taking support testing, and particularly relates to a thrombus taking support recovery force testing tool. Background The thrombus taking support recovery force testing tool is a special tool for evaluating acting force required by the thrombus taking support in the recovery process, the design principle is based on simulating the recovery scene of the support in actual operation, the support is connected with a force sensor through a specific structure, and pulling force is applied under a controllable condition and data are recorded. The tool has the core effects of quantifying the recovery force of the bracket and ensuring that the recovery force meets the clinical operation requirement, and if the recovery force is too large, vascular injury can be caused, and if the recovery force is too small, the bracket can be triggered to be unloaded. The method is characterized in that the application field focuses on the links of research and development and quality control of medical instruments, the material formula and structural design are optimized by testing the recovery force characteristics of the brackets with different specifications, and in the production link, sampling detection is carried out on the finished bracket to verify whether the recovery performance of the finished bracket meets the industry standard or not, so that the closed loop structure is ensured not to generate a fish mouth effect or a clamping phenomenon in the recovery process, and the safety and the effectiveness of an operation are ensured.
