The plasma scalpel, a new type of thermal knife, was investigated to determine its utility in neurosurgery. A series of 23 dogs underwent cortical resections comparing the use of the plasma scalpel with conventional bipolar cautery. Tissue heating, blood loss, speed of coagulation, wound healing and pathological change associated with use of the plasma scalpel were studied. The device was found to be effective, safe and faster than bipolar cautery. At present, several technical problems, including the large size of the handpiece and the blast effect of the plasma beam, preclude preliminary human clinical trials.
对新型热刀——等离子手术刀在神经外科手术中的效用进行了研究。对23只狗进行了一系列皮质切除术，比较了等离子手术刀与传统双极电灼的使用情况。研究了与使用等离子手术刀相关的组织加热、失血、凝血速度、伤口愈合和病理变化。结果发现该设备有效、安全且比双极电灼更快。目前，包括手持件尺寸较大和等离子束的冲击效应在内的几个技术问题妨碍了初步的人体临床试验。
