摘要： An electrocautery device is disclosed. In accordance with one aspect of the invention, the electrocautery electrode/tip is provided with a hollow, conductive tube terminating at its distal end in a ball point type tip. Fluid, preferably conductive fluid, is applied to the proximal end of the hollow electrode/tip, and expelled from the distal end thereof during electrocautery. The conductive fluid is supplied by a pressurized canister. The ball point distal tip allows the distal tip to be directly applied to the tissue and "rolled" or slid along the tissue. This allows the distal tip to be moved across the tissue without dragging or snagging on the tissue. In addition, the conductive fluid expelled from the distal tip further lubricates the distal tip as it moves across the tissue. If conductive fluid is used, the conductive fluid emanating from the electrode/tip conducts the RF electrocautery energy away from the distal tip so that it is primarily the fluid, rather than the distal tip that actually accomplishes the cauterizing of tissue. That is, the fluid serves as a "virtual" electrocautery electrode. Since it is the fluid, rather than the distal tip that cauterizes, coagulates and ablates, no burns or perforations are made to the tissue, reducing the amount of debris at the site. Also, the flow of fluid through the electrode/tip tends to keep the distal tip clean and cool.
摘要翻译：公开了电灼装置。根据本发明的一个方面，电烙电极/尖端设置有中空导电管，其末端终止于球形尖端。流体，优选导电流体被施加到中空电极/尖端的近端，并且在电烙术期间从其远端排出。导电流体由加压罐供应。球头远侧末端允许远侧末端直接施加到组织并且“滚动”或沿着组织滑动。这允许远端尖端移动穿过组织而不会在组织上拖动或阻塞。此外，从远侧末梢排出的导电流体在远侧末梢移动穿过组织时进一步润滑远端。如果使用导电流体，则从电极/尖端发出的导电流体将RF电灼能量远离远端尖端传导，使得其主要是流体，而不是实际完成组织烧灼的远端。也就是说，流体用作“虚拟”电烙电极。由于它是流体，而不是灼烧，凝结和消融的远端，不会对组织造成烧伤或穿孔，减少了现场的碎屑量。此外，通过电极/尖端的流体流趋于使远端保持清洁和冷却。
