A disposable loading unit for operable attachment to a surgical stapling apparatus. The disposable loading unit may have a carrier that supports a staple cartridge and an anvil assembly that is movable coupled to the carrier. The various embodiments may further have an axial drive assembly that is configured to impart a closing motion to the anvil assembly and also supports a cutting blade thereon. The axial drive assembly is configured to receive firing motions and retraction motions from the surgical stapling apparatus. Various embodiments have an anvil release assembly that enables the anvil assembly to be released from a clamping orientation in the event that the cutting blade becomes jammed during operation.
A disposable loading unit for attachment to a surgical stapling apparatus, said disposable loading unit comprising:
A disposable loading unit for attachment to a surgical stapling apparatus, said disposable loading unit comprising:
A disposable loading unit for attachment to a surgical stapling apparatus, said disposable loading unit comprising:
A disposable loading unit for attachment to a surgical stapling apparatus, said disposable loading unit comprising:
A disposable loading unit for attachment to a surgical stapling apparatus, said disposable loading unit comprising:
A surgical stapling apparatus, comprising:
An axial drive assembly for a surgical instrument having an anvil assembly movable between an open and closed positions relative to a staple cartridge supported therein, said axial drive assembly comprising:
An anvil release assembly for a surgical instrument having an anvil that is movable between an open and closed positions in response to opening and closing forces applied thereto by a distal end of an axial, drive assembly of the surgical instrument, wherein the anvil release assembly selectively causes the axial drive assembly to discontinue imparting the closing force to the anvil assembly regardless of where the distal end portion of the axial drive assembly is located along the anvil, said anvil release assembly comprising a support assembly movably supported by said anvil assembly and being selectively movable between a first position wherein said distal end portion of said axial drive assembly imparts said closing force thereto and retracted positions wherein said distal end portion of said axial drive assembly cannot impart said closing force thereto to thereby enable said anvil assembly to move to said open position.
An anvil release assembly for a surgical instrument having an anvil that is movable between an open and closed positions in response to opening and closing forces applied thereto by a distal end of an axial drive assembly of the surgical instrument, wherein the anvil release assembly selectively causes the axial drive assembly to discontinue imparting the closing force to the anvil assembly regardless of where the distal end portion of the axial drive assembly is located along the anvil, said anvil release assembly comprising a retainer movably supported by said anvil assembly and releasably coupled to said distal end portion of said axial drive assembly such that upon application of the retraction motion to said axial drive assembly, said retainer is decoupled therefrom to thereby enable the anvil assembly to move to the open position.
An anvil release assembly for a surgical instrument having an anvil that is movable between an open and closed positions in response to opening and closing forces applied thereto by a distal end of an axial drive assembly of the surgical instrument, wherein the anvil release assembly selectively causes the axial drive assembly to discontinue imparting the closing force to the anvil assembly regardless of where the distal end portion of the axial drive assembly is located along the anvil, said anvil release assembly comprises:
An axial drive assembly for a surgical instrument having an anvil portion movable between an open and closed positions relative to a staple cartridge supported in the surgical instrument, wherein the anvil portion has an anvil cover and a longitudinal slot therein through which a distal end of the axial drive assembly may move, said axial drive assembly comprising:
