We have developed an ultrasonic scalpel for laparoscopic use using the porcine cholecystectomy model. Based on experimentation with various blades, the hook-spatula blade appears to offer the best mix of coagulation and cutting. The advantages of this device are that it does not make smoke, causes minimal tissue injury, is safe to the surgeon and patient, and facilitates dissection. We believe it has the potential to become the preferred energy form for therapeutic laparoscopic surgery.
我们利用猪胆囊切除术模型开发了一种用于腹腔镜手术的超声手术刀。基于对各种刀片的实验，钩形刮铲刀片似乎在凝血和切割方面表现最佳。该设备的优点是不产生烟雾，对组织损伤最小，对手术医生和患者安全，并且便于解剖。我们认为它有潜力成为治疗性腹腔镜手术的首选能量形式。
