  • Publication number: 20070039997
    Abstract: A rotating surgical stapler having a proximal end and a distal end includes a handle at the proximal end and an end effector at the distal end for selective rotation to improve access to tissue requiring treatment and ease of use of the present linear surgical stapler. A support shaft connects the handle to the end effector and includes a longitudinal axis. The end effector is coupled to the support shaft for rotation about a longitudinal axis of the stapler.

  • Publication number: 20070039996
    Abstract: An articulating surgical stapler having a proximal end and a distal end includes a handle at the proximal end and an end effector at the distal end for selective articulation to improve access to tissue requiring treatment and ease of use of the present linear surgical stapler. A support shaft connects the handle to the end effector. An articulation mechanism is positioned between the support shaft and the end effector permitting selective movement of the end effector relative to the support shaft.

  • Publication number: 20070029364
    Abstract: A linear surgical stapler adapted for applying a plurality of surgical fasteners to body tissue includes an anvil structure and a cartridge housing containing a plurality of surgical fasteners. The cartridge housing and anvil structure are relatively movable between a first spaced apart position and a second position in close approximation with one another. A firing mechanism is associated with the cartridge housing for ejecting the surgical fasteners from the cartridge housing to be driven against the anvil structure. A lockout mechanism interacts with the cartridge housing for selective activation and deactivation. The lockout mechanism includes a swing gate tab secured to the cartridge housing at a position adjacent a lockout lever, such that firing of the linear surgical stapler rotates the swing gate tab releasing the lockout lever for preventing further firing of the used cartridge housing.

  • Publication number: 20050247753
    Abstract: A surgical instrument for applying a plurality of surgical fasteners to body tissue. The surgical instrument includes a frame having a proximal end and a distal end, with a handle at the proximal end and a support structure at the distal end. The support structure is adapted to support cartridge containing the plurality of surgical fasteners. The instrument further includes a closure member for supporting at least a portion of the cartridge for movement from a proximal end of the support structure to a distal end of the support structure, wherein at least a portion of the closure member is made from plastic.

  • Publication number: 20050246880
    Abstract: A method of manufacturing a surgical instrument for deploying a plurality of surgical fasteners. The method uses the step of building a frame with a proximal end and a distal end, and assembling a handle onto the proximal end of the frame. The method also involves the step of building a support structure at least partially from aluminum, such that the support structure is adapted to a plurality of surgical staples. The method also involves the step of assembling the support structure onto the distal end of the frame.

  • Publication number: 20050246881
    Abstract: A method of manufacturing a surgical instrument for deploying a plurality of surgical fasteners. The method uses the step of building a frame with a proximal end and a distal end, and assembling a handle onto the proximal end of the frame. The method then uses the step of building a support structure adapted to support cartridge containing the plurality of surgical fasteners, and assembling the support structure onto the distal end of the frame. The method also uses the step of building a closure member for supporting at least a portion of the plurality of surgical fasteners for movement from the open position to the closed position. Wherein the step of building the closure member uses the step of molding the closure member from a plastic.

  • Publication number: 20050145673
    Abstract: A surgical instrument adapted for applying a plurality of surgical fasteners to body tissue includes a frame having a proximal end and a distal end, with a handle positioned at the proximal end. The instrument also includes a cartridge housing and an anvil. The cartridge housing and anvil are relatively movable between a first spaced apart position and a second position in close approximation with one another, and the cartridge housing includes a knife adapted for cutting tissue by moving between the cartridge housing and the anvil. A firing mechanism is associated with the cartridge housing for selective actuation. The instrument also includes a tissue retention feature having an upper member and a lower member maintaining tissue between the cartridge housing and the anvil during treatment, wherein the upper and lower members respectively include channels associated with the knife for guiding it between the cartridge housing and the anvil.

  • Publication number: 20050139633
    Abstract: A surgical instrument is adapted for stapling tissue in a highly controlled manner. The surgical instrument includes a frame having a proximal end and a distal end, with a handle positioned at the proximal end and an end effector positioned at the distal end. The end effector is shaped and dimensioned for selectively receiving a cartridge module containing a plurality of surgical fasteners. A firing mechanism is associated with the end effector and the cartridge module for selective actuation of the surgical fasteners. The cartridge module includes a cartridge housing in which the surgical fasteners are housed and an anvil shaped and dimensioned for engagement with the surgical fasteners to facilitate stapling. The cartridge housing and anvil are relatively movable between a first spaced apart position and a second position in close approximation with one another.
