Adapter assemblies for interconnecting surgical loading units and handle assemblies
First Claim
1. An adapter assembly configured to be coupled to a surgical loading unit, the adapter assembly comprising:
- a switch configured to be toggled in response to the surgical loading unit being coupled to the adapter assembly;
an elongated member in communication with the switch, wherein the elongated member is resiliently biased in a distal direction toward a locking position in which the switch is toggled; and
an annular member disposed adjacent the elongated member, wherein the annular member is rotatable relative to the elongated member between a first orientation, in which the annular member prevents distal movement of the elongated member, and a second orientation, in which the elongated member moves distally to toggle the switch.

Abstract
An adapter assembly configured to be coupled to a surgical loading unit includes a switch, an elongated member, and an annular member. The switch is configured to be toggled in response to the surgical loading unit being coupled to the adapter assembly. The elongated member is in communication with the switch and is resiliently biased in a distal direction toward a locking position in which the switch is toggled. The annular member is disposed adjacent the elongated member and is rotatable between a first orientation, in which the annular member prevents distal movement of the elongated member, and a second orientation, in which the elongated member moves distally to toggle the switch.

10. A surgical instrument, comprising:
-
a surgical loading unit having a proximal end including at least one protrusion; and an adapter assembly having a proximal end configured to be coupled to a handle assembly and a distal end configured to be coupled to the proximal end of the surgical loading unit, the adapter assembly including; a switch configured to be toggled in response to the surgical loading unit being coupled to the distal end of the adapter assembly; an elongated member having a proximal end in communication with the switch and a distal end, wherein the elongated member is resiliently biased in a distal direction away from a non-locking position and toward a locking position in which the switch is toggled; and an annular member disposed adjacent the distal end of the elongated member and including at least one appendage configured to abut the at least one protrusion of the surgical loading unit upon coupling the surgical loading unit with the adapter assembly, wherein the annular member is rotatable relative to the elongated member between a first orientation, in which the at least one appendage is engaged to the distal end of the elongated member to maintain the elongated member in the non-locking position and a second orientation, in which the at least one appendage is disengaged from the distal end of the elongated member such that the elongated member moves to the locking position to toggle the switch. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A surgical instrument comprising:
-
a handle assembly; a surgical loading unit having a proximal end including at least one protrusion; and an adapter assembly having a proximal end configured to be coupled to the handle assembly and a distal end configured to be coupled to the proximal end of the surgical loading unit, the adapter assembly including; a switch configured to be toggled in response to the surgical loading unit being coupled to the distal end of the adapter assembly, wherein the switch is electrically connected with the handle assembly such that upon engagement of the surgical loading unit with the adapter assembly the switch communicates to the handle assembly at least one of an indicator that the surgical loading unit is coupled to the adapter assembly or at least one parameter pertaining to the surgical loading unit; an elongated member having a proximal end in communication with the switch and a distal end, wherein the elongated member is resiliently biased in a distal direction away from a non-locking position and toward a locking position in which the switch is toggled; and an annular member disposed adjacent the distal end of the elongated member and including at least one appendage configured to abut the at least one protrusion of the surgical loading unit upon coupling the surgical loading unit with the adapter assembly, wherein the annular member is rotatable relative to the elongated member between a first orientation, in which the at least one appendage is engaged to the distal end of the elongated member to maintain the elongated member in the non-locking position and a second orientation, in which the at least one appendage is disengaged from the distal end of the elongated member such that the elongated member moves to the locking position to toggle the switch.
