    摘要: The present invention relates to ultrasonic surgical clamping instruments and, more particularly, to a curved clamp arm tissue pad attachment for use with ultrasonic surgical instruments. A curved clamp arm for use with an ultrasonic surgical instrument is described. The curved clamp arm includes a proximal end and a distal end, with a top surface extending from the proximal end to the distal end of the curved clamp arm. The top surface comprises at least one hole. The clamp arm includes a bottom surface opposite the top surface, with the bottom surface extending from the proximal end to the distal end of the clamp arm. The bottom surface includes at least one engaging surface, where the hole in the top surface extends from the top surface to the engaging surface of the clamp arm. One embodiment of the curved clamp includes a plurality of the holes in the top surface, and a plurality of the engaging surfaces in the bottom surface, wherein each hole in the top surface extends through the curved clamp arm, terminating at a corresponding engaging surface on the bottom surface. The plurality of holes may also be staggered laterally from the proximal end of the clamp arm to the distal end of the clamp arm.

    摘要: A bipolar electrosurgical instrument having a pair of relatively moveable jaws, each of which includes a tissue contacting surface. The tissue contacting surfaces of the jaws are in face-to-face relation with one another, and adjacent each of the tissue contacting surfaces are first and second spaced-apart electrodes that are adapted for connection to the opposite terminals of a bipolar RF generator so as to generator a current flow between the electrodes. The first and second electrodes of one jaw are in offset opposed relation, respectively, with the first and second electrodes of the other jaw. A cutting portion is provided between the jaws. The cutting portion is moveable to provide the instrument with a scissors-like capability or a grasper-like capability, depending on the position of the cutting portion. A tissue dam is included on at least one jaw to help contain tissue within the desired coagulation area, and thereby help contain current density between the electrodes, thereby decreasing lateral tissue thermal damage and increasing hemostasis.

    摘要: A surgical fastener including a filament formed into a generally helical shape around a fastener axis and having a plurality of coils. The proximal end of the filament has an engagement member and the distal end of the filament has a penetrating tip. The engagement member may be driven to rotate the penetrating tip about the fastener axis such that the coils screw into tissue held in the path of the penetrating tip.

    摘要: A flexible endoscopic clip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is arranged adjacent to the jaw assembly and a clip pusher is arranged adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and the lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a distal portion. The threaded portion engages a threaded member near the pusher and is coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.
