摘要： A method and apparatus for creating a virtual electrode to ablate bodily tissue. The apparatus includes an outer tube, a first electrode, an inner tube and a second electrode. The outer tube is fluidly connected to a source of conductive fluid and defines a proximal end and a distal end. The distal end includes an opening for delivering conductive fluid from the outer tube. The first electrode is disposed at the distal end of the outer tube for applying a current to conductive fluid delivered from the outer tube. The inner tube is coaxially received within the outer tube and is connected to a source of conductive fluid. The inner tube defines a proximal end and a distal end, with the distal end forming an opening for delivering conductive fluid from the inner tube. Finally, the second electrode is disposed at the distal end of the inner tube for applying a current to conductive fluid delivered from the inner tube. With this configuration, upon final assembly, the distal end of the outer tube is axially spaced from the distal end of the inner tube such that the first electrode is spaced from the second electrode. As a result, a bi-polar virtual electrode can be established.

摘要： A surgical apparatus for delivering a conductive fluid to a target site for subsequent formation of a virtual electrode to ablate bodily tissue at the target site by applying a current to the delivered conductive fluid. The surgical apparatus includes an elongated device forming a helical needle. The helical needle is configured to engage bodily tissue and is hollow for delivering conductive fluid from a fluid source. Finally, the helical needle terminates in a needle tip. In one preferred embodiment, an electrode is associated with the helical needle for applying a current to conductive fluid delivered from the helical needle. During use, following delivery of conductive fluid, the electrode applies a current to the delivered conductive fluid for creating a virtual electrode. The virtual electrode ablates bodily tissue contacted by the conductive fluid.

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 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： An electrosurgery medical device is enhanced with unique solution-assistance, and comprises, in combination, co-operating device jaws including jaw portions for manipulating tissue, and a plurality of solution infusion openings defined and spaced along each of the jaw portions, for receiving electrolytic solution and infusing the solution onto and into tissue to be manipulated, along said jaw portions. As preferred, the device further comprises at least one, and most preferably, many, longitudinal groove(s) along at least one and most preferably, both, of the jaw portions, with the solution infusion openings located in the groove or grooves. The solution is energized with RF energy and contributes to the functions and beneficial effects of the instrument. The solution exits the openings in the grooves at sufficient flow rates to separate substantially all the operative surfaces of the device from tissue, thereby substantially completely preventing adherence between the operative surfaces and tissue. The solution is further energized to a range of energy densities such that tissues to be affected are sealed against flow of blood, lymphatic fluids, air, and other bodily fluids and gases.
摘要翻译：通过独特的解决方案辅助来增强电外科医疗装置，并且组合包括用于操纵组织的合作装置夹爪和用于操纵组织的颚部，以及沿着每个钳口部分限定和间隔开的多个溶液灌注开口，用于接收电解溶液并将溶液注入并进入待操作的组织中，沿着所述钳口部分进行操作。优选地，该装置还包括至少一个，并且最优选地，沿着至少一个，最优选两个钳口部分的纵向槽，溶液注入口位于槽或凹槽中。该解决方案通过射频能量通电，并有助于仪器的功能和有益效果。溶液以足够的流速离开槽中的开口，以将装置的基本上所有的操作表面与组织分离，从而基本上完全防止了操作表面和组织之间的粘附。该溶液进一步通电到一定范围的能量密度，使得受影响的组织被密封以抵抗血液，淋巴液，空气和其它体液和气体的流动。

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/尖端设置有中空的导电管，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。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。这允许远侧末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端处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，减少了现场的碎片数量。此外，通过电极/尖端的流体流趋向于保持远端尖端清洁和冷却。
