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. In addition, each of the presently disclosed cartridge and anvil half-sections of the fastener applying apparatus includes a clamping lever, which clamping levers are configured and adapted to enable the applying apparatus to be opened by either one of the cartridge half-section and the anvil half-section.

9. A surgical fastener applying apparatus, comprising:
-
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 having;
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;
whereupon both loading of the loading unit in the surgical fastener applying apparatus and clamping of the cartridge and anvil half-sections moves the lockout mechanism to an unlocked position to allow advancement of the member. - View Dependent Claims (10, 11, 12)

13. A surgical fastener applying apparatus, comprising:
-
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 replaceable staple cartridge assembly selectively receivable in the cartridge half-section, the replaceable staple cartridge assembly including;
a plurality of surgical staples;
a plurality of staple pusher members; and
a lock-out, the lock-out being movable between an initial substantially horizontal position and a vertical blocking position extending between the cartridge and anvil half-sections, wherein the lock-out prevents the cartridge half-section and anvil half-section from returning to the clamped position after the plurality of staples have been at least partially fired. - View Dependent Claims (14, 15, 16)

17. A surgical fastener applying apparatus, comprising:
-
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 replaceable staple cartridge assembly selectively receivable in the cartridge half-section, the replaceable staple cartridge assembly including;
a plurality of surgical staples;
a plurality of staple pusher members; and
a lock-out movable between an initial position permitting a relative movement of the cartridge half-section and anvil half-section to said clamped position and a blocking position preventing a relative movement of said cartridge half-section and anvil half-section to said clamped position after said plurality of staples have been at least partially fired, wherein the lock-out is confined between planes defined by opposed lateral side walls of said cartridge half-section when in the initial and blocking positions. - View Dependent Claims (18, 19, 20)
