First Claim
1. A receiving assembly for releasably coupling a loading unit to an adapter of a surgical instrument, the receiving assembly comprising:
- a load link including a link body having a distal portion;
a tip housing including a housing body defining a longitudinal slot and a lock opening; and
a locking member including a member body having an upper surface, a lower surface, and a locking tab, the member body of the locking member disposed within the longitudinal slot of the tip housing, the locking member being pivotable between an unlocked position, wherein the locking tab is positioned within the lock opening, and a locked position, wherein the locking tab extends through the lock opening, wherein the distal portion of the load link is moveable into engagement with the member body of the locking member to pivot the locking member from the unlocked position to the locked position.

Abstract
A receiving assembly for releasably coupling a loading unit to an adapter while preventing inadvertent actuation of the loading unit includes a load link, a tip housing, and a locking member. The load link includes a distal portion and the tip housing defines a longitudinal slot and a lock opening. The locking member includes a member body and a locking tab extending from a lower surface thereof. The member body is disposed within the longitudinal slot of the tip housing. The locking member is moveable between an unlocked position such that the locking tab is positioned within the lock opening and a locked position such that the locking tab extends from the lock opening. The distal portion of the load link engages the member body of the locking member to pivot the locking member from the unlocked position to the locked position.

4. A receiving assembly for releaseably coupling a loading unit to an adapter of a surgical instrument, the receiving assembly comprising:
-
a load link including a link body having a distal portion; a tip housing including a housing body defining a longitudinal slot and a lock opening, the tip housing including a coupling nub protruding from the housing body aligned with and proximal to the lock opening; and a locking member including a member body having an upper surface, a lower surface, and a locking tab, the member body of the locking member disposed within the longitudinal slot of the tip housing, the locking member being moveable between an unlocked position, wherein the locking tab is positioned within the lock opening, and a locked position, wherein the locking tab extends through the lock opening, wherein the distal portion of the load link is moveable into engagement with the member body of the locking member to pivot the locking member from the unlocked position to the locked position, the longitudinal slot extending into the coupling nub and the locking member including a proximal locking tab, the proximal locking tab extending from the upper surface of the member body and positioned within the coupling nub.

10. An adapter for releasably coupling a loading unit to a surgical instrument, the adapter comprising:
-
an outer tube having proximal and distal ends and defining a longitudinal axis; a coupling member defining a coupling opening adjacent a distal end thereof; a control rod positioned along the longitudinal axis of the outer tube and defining a locking slot, the control rod being longitudinally translatable along the longitudinal axis between a retracted position and an advanced position; a tip housing including a housing body defining a passage, a longitudinal slot, and a lock opening in communication with the passage and the longitudinal slot, the passage receiving the control rod; a load link including a link body having a distal portion; and a locking member including a member body having an upper surface, a lower surface, and a locking tab extending from the lower surface of the member body, the member body of the locking member disposed within the longitudinal slot of the tip housing, the locking member being moveable between an unlocked position in which the locking tab is positioned outside of the locking slot of the control rod and a locked position in which the locking tab is positioned in the locking slot of the control rod to prevent longitudinal translation of the control rod, the distal portion of the load link being moveable into engagement with the member body of the locking member to move the locking member from the unlocked position to the locked position. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
