摘　　要：本文介绍的生物组织超声乳化吸除技术，借助超声波技术，将电能转化成高频机械振动形式的功能，利用其产生的高于生物组织最小切割阈值的强大瞬时冲击加速度、声激流和空化的共同作用，对已病变和不需要的生物组织进行切割、报政和乳化，同时利用负压将乳化组织吸除掉，起到手术治疗的作用。Technique of ultrasonic emulsifying and drawing away on biological tissue can achives the purpose of operating treatment. Having the aid of ultrasonic wave techniquc,it transforms electronic energy into kinetic energy of high frequency mechanical vibration. Making use of the function of stronger instantaneous shock acceleration more than the minium cutting threshold of biological tissue, it cuts biological tissue pathologically changed and not needed,then smashes and emulsifies it, draws away the emulsified tissue by pump system.
