以往治疗胰腺癌、肝癌等腹腔内肿瘤的方法,如手术、放疗、化疗等效果均不理想。而且,这几种方法在切除或杀灭癌细胞的同时,对机体和正常组织会带来一定的损伤和副作用。近几年,一种既能杀灭癌细胞,又不损伤正常组织的新技术已开始应用于临床,这就是高能聚焦超声刀(简称超声刀)技术。 In the past, methods for treating intra-abdominal tumors such as pancreatic cancer and liver cancer, such as surgery, radiotherapy, and chemotherapy, were not satisfactory. Moreover, these methods can cause some damage and side effects to the body and normal tissues while removing or killing cancer cells. In recent years, a new technology that can kill cancer cells without damaging normal tissues has begun to be applied in clinical practice. This is the technique of high-power focused ultrasonic knife (abbreviated as ultrasonic knife).
