  • Patent number: 11918216
    Abstract: An adapter assembly includes a switch actuator, an actuation bar, and a latch. The switch actuator is movable between a proximal position, in which the switch actuator actuates a switch, and a distal position. The latch is movable between a first position, in which the latch permits proximal movement of the switch actuator, and a second position, in which the latch prevents proximal movement of the switch actuator. The latch is configured to move from the first position toward the second position in response to the actuation bar moving toward a proximal position.

  • Patent number: 11547394
    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.
