    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 surgical stapling instrument including a staple sled which can be advanced and/or retracted relative to first and second jaw members, wherein the staple sled can be configured to deploy staples from a staple cartridge in one of the first and second jaw members. In at least one embodiment, the other of the first and second jaw members can include an anvil having at least one forming surface which can be configured to deform the staples as they are deployed from the staple cartridge. In at least one form of the invention, the anvil can be movably adjustable relative to the staple cartridge in order to adjust the distance in which the staples are deformed. In various embodiments, the anvil can be adjusted by a slidable adjusting plate and/or a rotatable cam.
