摘要： 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.

摘要： An adapter assembly includes an elongated body, a circuit assembly, and an annular member. The elongated body includes a proximal portion configured to couple to a handle assembly, and a distal portion configured to couple to a surgical loading unit. The circuit assembly is disposed within the distal portion of the elongated body and configured to be in communication with a handle assembly. The annular member is rotatably disposed within the distal portion of the elongated body and includes an electrical contact. The annular member is rotatable between a first orientation, in which the electrical contact of the annular member is electrically isolated from the circuit assembly, and a second orientation, in which the electrical contact of the annular member is electrically connected to the circuit assembly.

摘要： A surgical apparatus includes a handle, an elongate member and a switch actuator. The switch actuator includes an activation link and a switch plunger coupled to the activation link. An electric switch is mounted to the elongate member. A rotatable lock member is mounted to the elongate member and adapted for rotational movement between an unlocked condition and a locked condition. The rotatable lock member includes an actuator stop dimensioned to operatively engage the switch actuator to prevent movement of the switch actuator from a first longitudinal position to a second longitudinal position when in the unlocked condition, and to permit movement of the switch actuator to the second longitudinal position when rotated to the locked condition such that the switch plunger activates the switch. A loading unit is releasably couplable to the rotatable lock member and is secured relative to the elongate member when the rotatable lock member is in the locked condition.
