Patent 12102305 was granted and assigned to Covidien on October, 2024 by the United States Patent and Trademark Office.
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.
