超声手术装置的原理及临床应用

Principle and clinical application of ultrasonic surgical installation

超声治疗技术在近年来进入了一个突破性发展的历史时期,其核心在于超声外科手术装置的出现和发展。超声手术刀在工作时以较大的振幅和功率进行超声振动,根据各种人体组织的声学性质不同,手术中可以做到少出血或不出血,并针对不同的病情选择性地切除病变组织,保留正常组织,为临床所认可。本文较为详细地介绍了超声刀的原理、结构、分类及临床应用。

With the appearance and development of ultrasonic surgical installation, ultrasonic therapy enters on a new epoch. High-amplitude and high-power ultrasonic vibration produced during the operation, ultrasonic surgical installation can be used to decrease the amount of bleeding or stop bleeding according to the acoustic properties of different tissues. The part where pathological changes happen can be excised selectively by ultrasonic surgical installation. This article introduces the principle, structure, classification and clinical application of ultrasonic surgical installation in detail.
