As a core device for orthopedic implant testing, the Bone Screw Torsion Tester is specifically designed to evaluate the torsional resistance performance of bone screws during clinical use. It is widely applied in medical device manufacturing enterprises, third-party testing institutions, and scientific research institutes, serving as a key testing tool to ensure the safety and reliability of bone screw implantation.
This equipment features high-precision torque and angle measurement capabilities. The torque measurement range covers 0-500N·m with an accuracy of ±0.5% FS, and the angle measurement resolution reaches 0.01°. It can accurately capture the torque variation curve of bone screws during the torsion process, enabling precise testing of key performance indicators of bone screws such as torsional strength, yield torque, and fracture torque. This fully reflects the impact of bone screw materials, thread structures, and processing technologies on their torsional resistance performance.
In terms of test simulation, the equipment supports the simulation of various clinical working conditions. By replacing fixtures of different specifications, it can meet the testing needs of various types of bone screws, including cortical bone screws and cancellous bone screws. Meanwhile, it can simulate the torsional stress state of bone screws in different bone tissues (such as simulated cortical bone and cancellous bone materials), reproducing the
design optimization and quality verification.
In addition, the equipment is equipped with an intelligent operating system and a 10-inch touch screen. It has built-in test procedures that comply with international and domestic standards such as ISO 6475 and GB/T 23806, supporting custom setting of test parameters, automatic data collection and analysis, as well as the generation and export of detailed test reports. At the same time, it is equipped with safety functions such as overload protection and emergency shutdown to ensure the safety and stability of the test process, providing an efficient and accurate testing solution for the quality control of orthopedic implants.
