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： A surgical obturator that includes an elongated shaft defining a longitudinal axis and an obturator member disposed adjacent a distal end of the elongated shaft. The obturator member may include a proximal section being convex along a majority of its length. It may also include a central section disposed adjacent the proximal section, the central section including a first pair of surfaces disposed relative to each other on radially opposite sides of the central section, and a second set of surfaces disposed between the first pair of surfaces and further being disposed relative to each other on radially opposite sides of the central section, at least a portion of a length of each one of the first pair of surfaces being concave, and at least a portion of a length of each one of the second pair of surfaces being convex. The obturator member may also include a guiding nub disposed distally of the central section and including a rounded distal-most portion. The rounded distal-most portion of the guiding nub may be atraumatic to tissue.

摘要： A surgical access assembly and method of use is disclosed, including an access member, a tissue engaging member, a sleeve extending from a portion of the membrane, and a fastening member to couple the access member and the sleeve. The access member includes proximal and distal ends, at least one lumen disposed therethrough, and defines a longitudinal axis. The tissue engaging member includes a membrane having proximal and distal ends with opposing openings, and a passage therethrough for receiving the access member. A length of the tissue engaging member may be selectively adjustable by a user so as to provide a retraction force. The sleeve extends proximally from a portion of the membrane. The sleeve has a proximal end and a distal end with opposing openings, the distal end of the sleeve defined by a portion of the membrane. A fastening member couples the access member and the sleeve.

摘要： A surgical access apparatus adaptable to permit the sealed insertion of either the surgeon's hand and/or surgical instruments during laparoscopic and endoscopic surgical procedures includes an access housing defining a longitudinal axis and having a first internal passageway configured and dimensioned to permit passage of at least one of a hand and an arm of a surgeon, and a base mountable to the access housing. The base may include a liner member positionable within an incision of a patient to at least partially line the incision. A displacement member may be operatively connected to the access housing and to the liner member. The displacement member is adapted for movement to cause corresponding displacement of the liner member relative to the access housing whereby the liner member engages tissue forming the incision to at least partially retract the incision.

摘要： A surgical portal apparatus includes a portal housing, a portal sleeve, and a seal. The portal housing defines a central housing axis and a central housing channel. The portal sleeve extends from the portal housing and is dimensioned to pass through tissue to provide access to underlying tissue via a longitudinal opening. The central housing channel of the portal housing and the longitudinal opening of the portal sleeve define a passageway for reception and passage of a surgical object. The seal has inner surfaces defining a seal passage for establishing a general sealed relation about the surgical object. The seal passage is radially offset with respect to the central housing axis. The seal is adapted to rotate about the central housing axis to vary positioning of the seal passage to substantially maintain the substantial sealed relation upon manipulation of the surgical object within the portal housing.
