高载能超声骨刀的优化设计与性能评估
Optimization design and performance evaluation of high-capacity ultrasonic bone scalpel
摘要
Abstract
Aiming at the problems of low cutting efficiency of ultrasonic bone scalpel and the generation of thermal damage of bone tissue during surgery,a high-capacity ultrasonic bone scalpel with a secondary amplification structure was designed.Based on the equivalent length method of standing wave theory and finite element simulation,the design and optimization of the secondary amplified structure were carried out,and the vibration performance was tested and the bone cutting test was conducted.The results show that the resonance frequency of the ultrasonic bone scalpel with secondary amplification structure is 23 306 Hz,the amplitude is 140 μm,and the bone cutting surface is flat and damage-free,which meets the needs of clinical surgery.关键词
