    摘要： A surgical clip applicator comprising a housing, a pair of handles pivotally connected to opposite sides of said housing, and a jaw blade assembly fixedly connected to the housing. The jaw blade assembly includes a pair of jaws for receiving and deforming a clip therebetween and a clip carrier for supplying a series of clips to said jaws. A channel assembly is slidably mounted in the housing and envelops said jaw blade assembly. A forming cam is connected between and to said handles and said channel assembly for sliding said channel assembly in a distal direction in response to closing of said handles together to move said jaws towards each other. A feed cam bar slidably mounted in said channel assembly in overlying relation to said clip carrier, said bar having a nose at its distal end. A pusher bar sidably mounted in said channel assembly for advancing clips along said clip carrier. A first spring member connected between said cam bar and said forming cam for sliding said cam bar in a proximal direction in response to closing of said handles together and further biasing said channel assembly in a proximal direction. Second spring member biasing said pusher bar in a distal direction to push a foremost clip in said clip carrier between said jaws in response to opening of said handles from each other. A clip retainer for preventing movement of said spring biased pusher bar is also provided.

    摘要： A handle for a laparoscopic instrument is provided for manipulating a distal laparoscopic tool. The handle includes a casing, a pivot handle pivotally attached to the casing, and an actuating shaft mechanism extending outward from the casing. Attached at the distal end of the actuating shaft opposite the casing is the laparoscopic surgical tool. The actuating shaft mechanism is longitudinally movable in a first direction by a pivotal movement of the pivot handle for manipulating the laparoscopic tool. A detent carried by the casing allows movement of the shaft longitudinally in the first direction while restraining longitudinal movement of the shaft in a second opposite direction. A thumb wheel attached to the actuating shaft mechanism allows the actuating shaft mechanism to be rotated for further manipulating the laparoscopic tool.

    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： A surgical fastening apparatus comprises first and second handles with an anvil jaw pivotally connected to at least one of the handles for movement from an open to a closed position in response to a first movement of a handle to clamp body tissue. Fastener pushing means are provided for advancing an individual fastener into contact with the anvil jaw in response to a subsequent movement of a handle. An indicator is provided to alert the user to the termination of the first movement; in a preferred embodiment this indicator is a second movement dwell period of the apparatus in which handle movement continues but the anvil jaw remains stationary and the fastener pushing means is not yet actuated. The apparatus further comprises means for preventing incomplete actuation of the fastener pushing means during the subsequent handle movement.

    摘要： A suture fastening device which includes a first member having a base and first and second legs projecting in a lengthwise direction along the base. The legs are parallel to each other and are resiliently biased toward a spaced apart position in relation to each other. A second member is provided and includes an aperture for receiving the first and second legs of the first member. The first and second members are connected by a hinge portion. A suture is held in serpentine fashion by positioning the suture transversely across both legs and locking the first member to the second member by forcing the legs through the aperture.
