Abstract

The present disclosure relates to surgical fastener applying apparatus for sequentially applying a plurality of surgical fasteners to body tissue. The surgical fastener applying apparatus includes a replaceable cartridge assembly receivable in a distal end portion of a cartridge receiving half-section, the cartridge assembly including a safety lockout pivotably disposed along the upper surface of the cartridge assembly and movable from an unlocked orientation permitting assembly of an anvil half-section to the cartridge receiving half-section, to a locked orientation preventing assembly of the anvil half-section to the cartridge receiving-half section.

Claims

1. A surgical fastener applying apparatus, comprising:

a cartridge half-section including a pair of upstanding juxtaposed plates extending from an upper surface thereof, wherein the pair of upstanding juxtaposed plates are located near a proximal end thereof, and wherein each plate defines a channel formed therein; and

an anvil half-section selectively matable with the cartridge half-section, the anvil half-section including a non-circular pin configured to selectively engage the channel formed in the pair of upstanding juxtaposed plates, wherein said cartridge and anvil half-sections are relatively movable from an unmated position to a mated position with one another via said non-circular pin engaging with the channel of the pair of upstanding juxtaposed plates and which non-circular pin defines an angle at which the cartridge half-section and the anvil half-section are properly mateable with one another from a position where they are separate and not in contact.

2. The surgical fastener applying apparatus of claim 1, wherein the non-circular pin has a substantially pear-shaped transverse cross-sectional profile.

3. The surgical fastener applying apparatus of claim 2, wherein the non-circular pin is located near a proximate end of the anvil half-section.

4. The surgical fastener applying apparatus of claim 1, wherein the predetermined angle is about 15°

.

5. The surgical fastener applying apparatus according to claim 1, wherein the non-circular pin is partially rotatable in the channel of the pair of upstanding juxtaposed plates.
