Abstract: 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.

Abstract: 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.

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.

Abstract: The present disclosure relates to adapter assemblies for use with and to electrically and mechanically interconnect electromechanical surgical devices and surgical loading units, and to surgical systems including hand held electromechanical surgical devices and adapter assemblies for connecting surgical loading units to the hand held electromechanical surgical devices.

Abstract: A force transmitting assembly of an adapter assembly includes a rotatable drive shaft, a strain sensor, and a drive member. The drive shaft includes a proximal portion, a distal portion, and a flange. The distal portion includes a threaded portion. The strain sensor is coupled to the drive shaft and disposed adjacent the flange such that longitudinal movement of the drive shaft imparts a force on the strain sensor via the flange. The distal drive member has a proximal end rotatably coupled to the threaded portion of the drive shaft and a distal end configured to be operatively coupled to a driven member of a surgical loading unit. Rotation of the drive shaft longitudinally moves the drive member relative to the drive shaft to actuate the surgical loading unit.

Abstract: A surgical instrument includes a handle assembly, a surgical loading unit, and an adapter assembly coupled therebetween. The adapter assembly includes a housing, an elongated body, a switch assembly, and a switch actuator. The elongated body extends distally from the housing and is configured to be coupled to the surgical loading unit. The switch assembly is disposed within the housing and configured to communicate that the surgical loading unit is coupled to the elongated body. The switch assembly includes a substrate, a switch mounted on the substrate, and at least one wire coupled to the substrate. The switch actuator is movably disposed within the housing and configured to actuate the switch upon engagement of the surgical loading unit with the elongated body.
