[Research on Self-tapping Performance Test of Self-tapping Bone Screws].

Area of Science:

• Biomaterials Engineering
• Orthopedic Device Testing
• Medical Device Standards

Background:

• Self-tapping bone screws are critical orthopedic implants.
• Standardized testing is essential for ensuring implant performance and safety.
• The YY/T 1505 standard provides a framework for evaluating self-tapping bone screws.

Purpose of the Study:

• To investigate and refine the self-tapping performance test method for self-tapping bone screws.
• To optimize factors influencing the self-tapping force test based on the YY/T 1505 standard.
• To improve the method for judging self-tapping force to enhance test reliability.

Main Methods:

• Referenced the YY/T 1505 standard for testing procedures.
• Optimized various factors affecting the self-tapping force test.
• Developed an improved method for judging self-tapping force.

Main Results:

• The improved self-tapping force judgment method demonstrated good repeatability.
• Experimental data exhibited high stability using the enhanced method.
• Test material and pre-drilled hole size were identified as key factors for manufacturers to consider.

Conclusions:

• An improved self-tapping force judgment method significantly enhances the repeatability and stability of test data.
• This study provides a valuable contribution to the self-tapping performance testing of self-tapping bone screws.
• Adherence to optimized testing parameters is crucial for reliable orthopedic implant evaluation.
