Surgical end effectors are disclosed having angled tissue-contacting surfaces. The end effectors may have a first jaw member that is movable relative to a second jaw member between an open position and a closed position. The first jaw member may have a first positively-angled tissue-contacting surface. The second jaw member may have a second positively-angled tissue-contacting surface. At least one of the jaw members may have at least one active electrode configured to deliver RF energy to tissue located between the first jaw member and the second jaw member when in the closed position.
摘要:
A rotary support joint assembly for coupling a first portion of a surgical instrument to a second portion of a surgical instrument. In various forms the joint assembly includes a first annular race in the first portion and a second annular race in the second portion. The second race is configured for substantial registration with the first annular race when the second portion is joined with the first portion. A ring-like bearing is supported within the registered first and second annular races.

Tissue manipulation devices are disclosed. In various forms, the devices include tissue manipulation arms that are arranged in a position suitable to enable the device to be inserted into the colon then, upon application of at least one actuation motion thereto, at least some of the tissue manipulation arms are moved to deployed positions wherein they contact corresponding portions of the colon to thereby expand the colon. Various devices are actuatable by various forms of actuation forces. In various embodiments, the tissue manipulation arms may be movable along corresponding axes that are transverse to an insertion axis and may also be rotated about the insertion axis as well as be moved in directions that are substantially parallel to the insertion axis.

Surgical access devices are disclosed. In various forms, the access devices form at least one passageway through which various surgical instruments and tools may be admitted into the body cavity. Various embodiments may be configured to support an anvil for a circular stapling device therein. Various forms employ a flexible bag for retrieval of specimen from the body cavity.
摘要:
A surgical cutting and fastening instrument. The instrument comprises an end effector that has a shaft coupled thereto that is coupled to a robotic system. A tool mounting portion includes an electric, DC motor connected to a drive train in the shaft for powering the drive train. A power pack that comprises at least one charge-accumulating device connected to the DC motor for powering the DC motor is provided.
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.
