  • Patent number: 5902264
    Abstract: An endoscopic surgical instrument for aspiration, irrigation, and blowing gas adjacent a surgical site is provided. The instrument includes a handle portion and a cannula member extending distally from the handle portion. First and second connection ports are supported by the handle and are in fluid communication with the cannula member. An insertion port is also supported by the handle portion and is preferably axially aligned with the cannula member. A blow tube is removably positioned within the cannula member via the insertion port. The first and second connection ports are adapted to communicate with a source of irrigation fluid and a vacuum source and the blow tube is adapted to be connected to a source of pressurized gas such that irrigation fluid, aspiration, and/or pressurized gas can be selectively provided via the cannula member at the surgical site.

  • Patent number: 5366134
    Abstract: 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.
