摘要： An improved surgical stapler having first and second pivotally interconnected structural members each including a handle portion and a jaw portion. The structural members are pivotally movable between a closed position wherein their jaw portions are in a closely spaced relationship to an open position wherein their jaw portions are spaced apart a substantial distance. A locking member is pivotally connected to one of the structural members for pivotal movement between a first position wherein the locking member is generally aligned with the structural member and a second position wherein the free end of the locking member is spaced apart from the outboard end of the structural member. When actuated, the locking member functions to forcefully move the structural members toward a closed position so that the tissue to be stapled can be securely clamped between the jaw portions of the instrument. A staple cartridge of novel design is removably connected to one of the first and second structural members and contains a plurality of staples for stapling together tissue disposed between the jaw portions of the instrument. A novel jaw stabilizing element is provided either on the staple cartridge or on the disposable anvil of the device for insuring proper spacing between the handle portions of the instrument and in this way functions to maintain optimum jaw closure for every tissue thickness by restricting the undesirable bending of the handle portions as the tissue to be stapled is compressed between the jaw portions.

摘要： A method and apparatus for filling a syringe-type applicator having multiple material reservoirs are disclosed. The method and apparatus permits the individual component reservoirs to be simultaneously filled without risk of contamination or unintentional component mixing. The method and apparatus are particularly useful in the preparation and delivery of multiple component tissue sealants such a fibrinogen adhesive compositions.

摘要： A medical fluid applicator for dispensing a fluid onto biological tissues in tissue adhesive or sealant applications includes a dispensing pathway with an audible loudness indicator that signals the cumulative amount of fluid delivered by varying the pitch or tone of audible signals emitted at discrete volumetric increments. A suction pathway is also included for applying vacuum pressure to the applicator tip contemporaneous with the fluid application. The medical fluid applicator further includes a clearing pathway for retrogradedly withdrawing coagulated mixed fluids, such as mixed two-part tissue adhesives, from the applicator tip. A valve manifold and a shuttle valve are actuated to adjust the operation of vacuum pressure in the device between the various suctioning, clearing, and venting conduits of the device. The valve manifold is also adapted to couple a vent pathway and the suction pathway simultaneously to the vacuum conduit adapted for connection to a vacuum source. The coupling of vacuum to these pathways may be selectively adjusted by use of inversely and reciprocally shaped valving apertures on the valve manifold, such that preselected levels of applied suction at the suction pathway may be achieved. The device also includes a supply device portion and an applicator portion removably coupled thereto. The supply device portion includes the proximal portions of the dispensing assembly including the audible loudness indicator and the fluid reservoirs. The applicator portion includes the suction conduit, the clearing conduit, and a mixing conduit for mixing the components of the fluid reservoirs immediately prior to fluid delivery. A filling dispenser is further provided which is keyed to engage the supply device portion of the device in a predetermined orientation such that each fluid reservoir of the supply device is coupled for filling from a specified, predetermined filling reservoir.
