  • Patent number: 7721933
    Abstract: A surgical fastener applying apparatus is provided including a cartridge half-section and an anvil half-section, the cartridge half-section and anvil half-section being relatively movable from an unclamped position to a clamped position; and a loading unit receivable in the cartridge half-section and having a plurality of staples and a plurality of staple pusher members. The cartridge half-section includes a frame; a member being longitudinally movable through the loading unit to interact with the plurality of staple pusher members to fire the staples; and a lockout mechanism arranged to block advancement of the member in a locked-out position of the lockout mechanism. In use, after loading of the loading unit in the surgical fastener applying apparatus and subsequent clamping of the cartridge and anvil half-sections, the lockout mechanism is moved to an unlocked position to allow advancement of the member.

  • Patent number: 7568604
    Abstract: An improved surgical fastener applying apparatus includes a cartridge half-section and an anvil half-section with the cartridge and anvil half-sections being relatively movable from an unclamped position to a fully clamped position. The apparatus includes a replaceable staple cartridge assembly having a plurality of surgical staples and a pivotably mounted safety lock-out. The safety lock-out is pivotable between an initial position in which a relative movement of the cartridge and anvil half-sections to the fully clamped position is permitted and a blocking position in which a relative movement of the cartridge and anvil half-sections to return them to their fully clamped position after the plurality of staples have been at least partially fired is prevented. The apparatus further includes a pivotably mounted firing lever for moving a pair of camming surfaces longitudinally.

  • Patent number: 6436054
    Abstract: A biopsy system is provided including a housing and a biopsy instrument operatively associated with the housing and configured and dimensioned to remove a tissue sample from a patient. A firing module is included that is detachably engageable with the housing and operatively associated with the biopsy instrument to facilitate selective rapid advancement of at least a portion of the biopsy instrument toward a targeted location with the patient. The biopsy instrument includes a tissue receiving portion. The system may include an indexing assembly disposed within the housing and configured to cooperate with the biopsy instrument to selectively orient the tissue receiving portion. The indexing assembly may include a manual gearing assembly configured for selective orientation of the tissue receiving portion. The system may include a linear advancement control assembly disposed within the housing and configured to effect linear actuation of a tubular knife member.

  • Patent number: 5938667
    Abstract: A surgical clip applier includes a housing, a pair of handles pivotably connected to opposite sides of the housing, a channel assembly which is anchored to the housing and a jaw assembly which is anchored to the channel assembly. The jaws are opened and closed by a cam plate which is slidably positioned in the channel assembly and is provided with cam slots at its distal end to engage drive rivets positioned on the jaw members. A pusher bar assembly is also provided to feed clips from a series of clips to the jaw mechanism, and the instrument operates such that all moving components move in the same direction during the closing stroke of the handle, and then move in the same direction opposite to the closing direction when the handles are in the opening stroke. A novel lockout mechanism is also provided to render the instrument inoperable after all the clips have been utilized from the instrument.

  • Patent number: 5868759
    Abstract: A surgical clip applier includes a housing, a pair of handles pivotably connected to opposite sides of the housing, a channel assembly extending from the housing and a jaw assembly. A pusher bar assembly is provided to feed clips from a series of clips to the jaw mechanism under the influence of a spring, and a damping mechanism is provided to generate a force on the pusher member to counteract the spring force and decelerate the distal advancement of the pusher member as a clip is fed to the jaw assembly.
