Features
1. High Precision and High Repeatability
The testing instrument is equipped with high-precision sensors that can accurately capture force changes at the millinewton level. Combined with an advanced control system that precisely adjusts testing parameters, it ensures consistency of test data across multiple tests and different scenarios. This provides reliable data support for enterprise product quality control (eliminating defective products, reducing quality risks, and ensuring patient safety) and R&D optimization (scientific analysis and improved product performance).
2. Strong Flexibility
The testing parameters (speed, force) and clamp gripping force can be flexibly adjusted according to different specifications and designs of surgical needles, such as triangular and round needles. This allows for accurate evaluation of the cutting performance of various surgical needles while avoiding damage to the needle body. It is compatible with testing both conventional and new special surgical needles, assisting enterprises in efficient quality inspection and new product development.
3. User-Friendly Human-Machine Interface
It features an intuitive touchscreen/computer control interface, making operation simple and easy to understand; it supports automatic generation of standardized reports containing key data (puncture force, cutting force, etc.) and trend charts, saving labor and reducing errors. Some advanced models also support real-time data monitoring and remote transmission, facilitating timely problem handling and cross-regional data sharing.
