摘要： An improved electrosurgical instrument includes a body having more than two electrodes with at least two electrodes having alternating current power supplied to them provide a bipolar alternating current configuration and employ a means other than electrode spacing for reducing or preventing accumulation of eschar. The electrodes are separated from each other using electrically insulating materials such that electric current does not flow between at least two of the bipolar alternating current electrodes unless they contact at least one other electrically conductive medium, such as patient tissue. The conductor edge portion and insulation layer each have geometric shapes and composition to reduce or eliminate the production of smoke and eschar and reduce tissue damage. The outer profile of the insulation layer and conductive element are configured to facilitate the flow of electrosurgical decomposition products away from the conductor edge where they are formed.

摘要： A ligation clip applicator design is provided that is particularly applicable to placement of a surgical ligation clip during a laparoscopic surgical procedure. The applicator has a magazine including first and second longitudinally extending partially closed channels within which enlarged portions of a ligation clip are received and held in an open position. First and second substantially parallel compression members are attached to the magazine and have first and second channel extensions therein aligned with the first and second channels of the magazine for receiving the first and second enlarged portions of the clip. The channel extensions include first and second releasing openings. The compression members close about a vessel, remaining substantially parallel as they close. The clip is pushed forward into the compression members to a position where the enlarged portions of the clip are aligned with the releasing openings, permitting the clip to be released to close and ligate the vessel.

摘要： A reusable tip for minimally invasive surgical instruments can include an end effector, a two-part hub, and a yoke. The end effector can include one or more movable portions enabling the end effector to move between first (e.g., open) and second (e.g., closed) positions via manipulation of the yoke within the hub. The hub can include a proximal hub and a distal hub coupled together. The end effector can be coupled to the distal hub, which can be made of a metal to provide high strength and secure shape to the distal hub. The proximal hub can be made of an autoclavable insulation material capable of maintaining a removable coupling with a control shaft. The proximal hub can be made of polyetheretherketone (PEEK).

摘要： A surgical instrument with insulating grips is described. The grips can include internal metal frames that are arranged to limit electrical conductivity within the grips and to other components that attach to a grip, such as a ratchet. The internal metal frames can be constructed of multiple internal portions, spatially separated from one another to interrupt electrical conductivity between the internal portions, but coated with an insulating overmold to provide mechanical coupling between the portions. An internal metal frame can also include a notch, cut-out, or other region partially surrounded by the structure of the internal metal frame, which can be coated with an insulating overmold to define a region of the grip that does not have an internal metal frame therein but which can include an attachment point for mechanically coupling other components while limiting electrical coupling between the metal frame and the other components.
