    摘要： A surgical instrument for performing an anastomosis includes a housing having proximal and distal ends and a shaft extending from the distal end of the housing. The instrument also includes an actuator attached to the housing and a disposable loading unit configured for selective attachment to the shaft. The disposable loading unit includes a fastener support member configured and dimensioned to support an array of surgical fasteners thereon and a fastener pusher member which is movable through a firing stroke in response to movement of the actuator to deform the surgical fasteners.

    摘要： An apparatus for manipulating a surgical needle is disclosed, comprising a body portion, a first needle receiving jaw mounted for movement on a distal end of the body portion and having a first needle engaging member, a second needle receiving jaw mounted for movement on the distal end of the body portion and having a second needle engaging member, the second needle engaging member being operatively interconnected to the first needle engaging member for relative reciprocal movement therewith, wherein each of the first and second needle receiving jaws has a recess for receipt of a portion of a surgical needle therein. The first and second needle engaging members are mounted for alternate reciprocal movement into and out of locking engagement with the surgical needle. The apparatus also includes a wheel rotatably mounted within the body portion with a proximal end portion of each of the first and second needle engaging members connected to opposing sides of the wheel such that rotation of the wheel simultaneously retracts one of the needle engaging members and advances the other. Also disclosed is a method of manipulating a surgical needle inside a body cavity using a surgical instrument having a control mechanism, a first jaw and a second jaw, where at least one of the jaws is mounted for movement between a first position adjacent the other jaw and a second position spaced apart from the other jaw.

    摘要： The present invention, in accordance with various embodiments thereof, relates to a surgical device for at least one of cutting and stapling a section of tissue. The surgical device includes a housing including at least two drivers. The surgical device also includes an anvil mechanically attachable to the housing and moveable relative to the housing between an open position and a closed position. The first driver operates to move the anvil relative to the housing to an intermediate position between the open position and the closed position. The second driver operates to move at least a portion of the housing relative to the anvil between the intermediate position and the closed position.
