摘要： A surgical instrument according to an embodiment of the present invention includes a housing portion and an endoscopic portion having a proximal end and a distal end, the endoscopic portion including a pair of coaxial members attached at the proximal end to the housing portion. The endoscopic portion also includes an inner rod member slidable within an outer tube member. The endoscopic portion terminates at the distal end in a pair of jaw members disposed in opposing relation and relatively pivotal about a common point between at least an open position and a closed position. A jaw control mechanism is associated with the housing portion, and includes at least one actuating member movably mounted in the housing portion. The actuation member has at least one gripping portion thereon such that an operator of the instrument can better manipulate the actuating member with a single hand. A linking member is pivotally connected to the actuating member and the inner rod member. A notch portion is disposed on the rod member such that when the actuating member is moved in relation to the housing portion in a first direction to a first position the engaging portion engages the notch, locking the jaws in a closed position. The surgical instrument also includes means for preventing the inner rod member from moving from the first position whereby coaxial reciprocating forces are created in the inner rod member when the locking means are moved to the first position.

摘要： An endoscopic swab device comprising an elongated housing, a swab operatively associated with a distal end of the elongated housing and a connection member for connecting the swab relative to the housing and extending through the housing. A rotatable member is positioned on the housing to engage the connection member and further prevents separation of the swab from the housing. The tautness of the swab may be adjusted by rotating the rotatable member which positions the swab longitudinally relative to the elongated housing.

摘要： An endoscopic surgical stapling apparatus is disclosed. The apparatus comprises a frame and a generally elongated endoscopic section connected to the frame and extending distally therefrom. The endoscopic section includes a mechanism for storing a plurality of staples, a mechanism for advancing the staples for positioning adjacent body tissue and a mechanism for at least partially closing each staple. A low pressure pneumatic system disposed in the frame provides the forces to at least partially activate the staple advancing mechanism. The apparatus has particular application in attaching mesh to body tissue as in laparoscopic hernia repair.

摘要： A detachable anvil assembly for use with an apparatus for performing circular anastomosis of tubular organs includes an elongated anvil rod having proximal and distal end portions and an anvil head mounted to the distal end portion of the anvil rod. The distal end portion is pivotally mounted and is adapted to pivot approximately plus or minus ninety degrees relative to a longitudinal axis defined by the rod. An elongated delivery member detachably receives the anvil assembly and facilitates delivery of the anvil assembly to the operative site. The pivoting feature of the distal end reduces the transverse profile of the assembly which consequently facilitates introduction and advancement of the anvil assembly within the tubular organ.
