“纯”纵向振动的圆形刀头的超声刀的研制（英文）
A design and study of ultrasonic scalpel of spherical tip in “pure” longitudinal vibration mode
摘要
Abstract
An ultrasonic scalpel with spherical tip,which operates in the high power low-frequency range 50~60 kHz for biological tissue cutting and removal,is designed based on the theory of elastic wave guide.In order to make the scalpel operated in a "pure" longitudinal vibration mode and have the largest output displacement of the tip as well as the least stress distribution in the scalpel body,the design is optimized with finite element method(FEM).According to the optimized design,the ultrasonic scalpel with spherical tip is produced and its output displacement of the spherical tip is measured with optical method.The experimental results are compared with FEM results.It shows that both are in agreement.关键词
