1. A surgical fastener applying apparatus comprising:
- an elongated cartridge section having a longitudinal axis;
an elongated anvil section, the cartridge and anvil sections being relatively movable from an unclamped position to a fully clamped position to clamp tissue therebetween;
a plurality of cam bars positioned in the cartridge section;
a cartridge containing a plurality of fasteners, the cartridge supported in the cartridge section and having a longitudinal axis;
a firing knob operatively associated with the cam bars to move the cam bars longitudinally to sequentially fire the plurality of fasteners in a direction transverse to the direction of movement of the cam bars;
a safety member supported in the cartridge section, the safety member mounted for movement between an initial position to allow relative movement of the cartridge and anvil sections to the clamped position and a blocking position to prevent relative movement of the cartridge and anvil sections to the clamped position after the fasteners have been fired, the safety member moving in a direction substantially transverse to the longitudinal axis of the cartridge and substantially transverse to the direction of movement of the fasteners.

Abstract
A surgical fastener applying apparatus having elongated cartridge and anvil half sections which are relatively movable from an unclamped to a clamped position. A safety member is supported in the cartridge section and movable between a non-blocking position and a blocking position to prevent relative movement of the cartridge and anvil support member to the clamped position after the fasteners have been fired. The safety member is biased inwardly by a tab retainer. Distal movement of the cam bars causes the tab retainer to be moved to a release position to allow movement of the safety tab to the blocking position.

13. A surgical fastener applying apparatus comprising:
-
an elongated cartridge supporting member having a longitudinal axis and first and second substantially parallel outer walls; an elongated anvil supporting member, the cartridge and anvil supporting members being relatively movable from an unclamped position to a clamped position to clamp tissue therebetween; a tissue stop mounted to the anvil supporting member; a plurality of cam bars supported in the cartridge supporting member; a plurality of fasteners supported in the cartridge supporting member; a firing knob operatively associated with the cam bars to move the cam bars longitudinally to sequentially fire the plurality of fasteners in a direction transverse to the direction of movement of the cam bars; and a blocking member supported in the cartridge supporting member and mounted for movement between a non-blocking position to allow relative movement of the cartridge and anvil supporting members to the clamped position and a blocking position to prevent relative movement of the cartridge and anvil supporting members to the clamped position after the fasteners have been fired, the blocking member contacting the tissue stop in the blocking position. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A surgical fastener applying apparatus comprising:
-
an elongated cartridge section; an elongated anvil section, the cartridge and anvil sections being relatively movable from an unclamped position to a fully clamped position to clamp tissue therebetween; a plurality of cam bars supported in the cartridge section; a plurality of fasteners supported in the cartridge section; a firing knob operatively associated with the cam bars to move the cam bars longitudinally to sequentially fire the plurality of fasteners in a direction transverse to the direction of movement of the cam bars; a safety mechanism supported in the cartridge section, the safety mechanism including a pivotable safety tab and a sliding tab retainer, wherein sliding movement of the tab retainer to a release position allows the safety tab to pivot to a blocking position to prevent reclamping of the cartridge and anvil sections, the tab retainer sliding to the release position upon distal movement of the firing knob. - View Dependent Claims (23, 24, 25, 26, 27)
