Surgical fastener applying apparatus
First Claim
1. A surgical fastener applying apparatus, comprising:
- a cartridge section having a loading unit, the loading unit including a cartridge body with staple retaining slots and a plurality of surgical staples;
an anvil section having an anvil surface for forming the plurality of surgical staples, the cartridge section and the anvil section being arranged to be joined to one another and relatively movable from an unclamped position to a clamped position;
a first clamp lever operatively connected to the cartridge section and a second clamp lever operatively connected to the anvil section, each clamp lever being movable from a closed position in which the cartridge section and the anvil section are in the clamped position to an open position in which the cartridge section and the anvil section are in the unclamped position, each clamp lever being movable to the open and closed position independently of the other clamp lever; and
a firing lever longitudinally movable to sequentially fire the plurality of surgical staples, wherein the firing lever is pivotable to extend from a selected one of a right and left side of the apparatus.

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.

13. A surgical fastener applying apparatus, comprising:
-
a cartridge section having a loading unit, the loading unit including a cartridge body with staple retaining slots and a plurality of surgical staples; an anvil section having an anvil surface for forming the plurality of surgical staples, the cartridge section and the anvil section being relatively movable from an unclamped position to a clamped position; a firing lever longitudinally movable to sequentially fire the plurality of surgical staples, wherein the firing lever is pivotably mounted to extend from a selected one of a right and a left side of the apparatus; a knife with a sharpened edge, the knife being arranged to move longitudinally with the firing lever; a lock-out, said lock-out being pivotable between an initial position permitting a relative movement of said cartridge section and anvil section to said clamped position and a blocking position preventing a relative movement of said cartridge section and anvil section from returning to said clamped position; and a shipping wedge removably coupled to said cartridge assembly and configured and adapted to cover the staple retaining slots, the lock-out and shipping wedge cooperating to cover the sharpened edge of the knife. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A surgical fastener applying apparatus, comprising:
-
a cartridge section having a removable loading unit, the loading unit including a cartridge body staple retaining slots arranged and a plurality of surgical staples; an anvil section having an anvil surface for forming the plurality of surgical staples, the cartridge section and the anvil section being relatively movable from an unclamped position to a clamped position; a firing mechanism movable to fire the plurality of surgical staples; a rocker pivotably mounted to said cartridge section and being biased toward a lock-out position in which the rocker blocks movement of the firing mechanism, the rocker having a distal end surface arranged to be engaged by the cartridge body, the cartridge body pivoting the rocker away from the lock-out position upon movement of the cartridge section and the anvil section to the clamped position to enable movement of the firing mechanism. - View Dependent Claims (21, 22, 23, 24)
