An adapter assembly includes an elongate body configured to receive a surgical loading unit and an elongate loading bar coupled to the elongate body and configured to selectively lock the surgical loading unit to the adapter assembly. The elongate loading bar has a distal end defining a slot therein configured for receipt of an articulation link of the surgical loading unit upon an improper insertion of the surgical loading unit into the adapter assembly. With the articulation captured in the slot, rotation of the surgical loading unit toward a fully assembled state with the adapter assembly is resisted.

A surgical stitching device is configured for single hand operation that enables passage of a suture needle through tissue with minimal operational requirement. The surgical needle is selectively securable to a tool assembly of the surgical stitching device. The tool assembly includes a jaw configured to securely support various surgical needles in various orientations.

A continuous strip of staples for use with a surgical stapling device includes an elongated stock of corrugated paper defining a plurality of channels therein. An inner facing side of each channel is configured to support a row of staples thereon and extending therealong and is configured to be slidingly received in a corresponding plurality of slots defined within a cartridge assembly of a stapling device for loading the staples therein. A plurality of indexing apertures is defined in the elongated stock and extends therealong. The plurality of indexing apertures is adapted to engage a staple deformation element of the cartridge assembly during retraction thereof to automatically reload one or more new rows of staples after actuation of the stapling device.
