摘要： The present invention relates, in general, to ultrasonic surgical clamping instruments and, more particularly, to an improved force limiting mechanism for an ultrasonic surgical clamping instrument. An ultrasonic clamp coagulator apparatus is described including a housing, an actuator, an outer tube having a proximal end joined to the housing, and a distal end. An actuating element is reciprocably positioned within the outer tube and operatively connected to the actuator. An ultrasonic waveguide is positioned within the outer tube, with an end-effector extending distally from the distal end of the outer tube. A clamp arm is pivotally mounted on the distal end of the outer tube for pivotal movement with respect to the end-effector for clamping tissue between the clamp arm and the end-effector. The clamp arm is operatively connected to the actuating element so that reciprocal movement of the actuating element pivots the clamp arm. There is an actuation mechanism within the housing, connected between the clamp arm and the actuator. The actuation mechanism is adapted to actuate the clamp arm pivotably with respect to the end-effector. In one embodiment the actuation mechanism includes a wave spring for limiting the force applied to the clamp arm from the actuator.

摘要： An electrosurgical stapling instrument includes an end effector capable of applying bipolar RF energy into tissue. The end effector has a first pole electrode and a second pole electrode for forming an RF contact circuit with tissue. At least one of the electrodes may have a dielectric coating thereon to create a RF circuit with tissue. The dielectric coating can cover one of the electrodes to create a capacitive coupling circuit with tissue, or can have at least one open passageway extending through the dielectric coating to enable tissue contact with the electrode and the passage of RF energy therethrough. The dielectric coating on the electrode can be masked to create passageways through the dielectric, or the dielectric coating can be locally removed with a variety of techniques to form passageways. The dielectric coating may provide a barrier to prevent shorting between the dielectrically coated electrode and a conductive fastener embedded within tissue. Alternately, a cartridge coating can be used to reduce an electric surface sheet charge on the cartridge thermoplastic that can occur during the application of RF energy to tissue.

摘要： A fastener cartridge can comprise a support portion, a tissue thickness compensator positioned relative to the support portion, and a plurality of fasteners positioned within the support portion and/or the tissue thickness compensator which can be utilized to fasten tissue. In use, the fastener cartridge can be positioned in a first jaw of a surgical fastening device, wherein a second jaw, or anvil, can be positioned opposite the first jaw. To deploy the fasteners, a staple-deploying member is advanced through the fastener cartridge to move the fasteners toward the anvil. As the fasteners are deployed, the fasteners can capture at least a portion of the tissue thickness compensator therein along with at least a portion of the tissue being fastened.
