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.

Adapter assembly for interconnecting electromechanical surgical devices and surgical loading units, and surgical systems thereof

A surgical stapling apparatus is provided and includes a housing having an actuator; an elongated member extending from the housing; an end effector disposed on an end of the elongated member, the end effector having a first jaw and a second jaw, the first jaw having a staple cartridge and the second jaw having a plurality of staple forming recesses; the staple cartridge having at least a first segment and a second segment, the first segment and the second segment each having a tissue contacting surface and staple receiving slots defined in the tissue contacting surface, the first segment and the second segment being biased toward the second jaw and movable; a biasing members for each of the first segment and the second segment; and a pressure sensor for each of the first segment and the second segment.

Surgical stapling apparatus

A surgical device includes a handle assembly including a controller and a first electrical connector. The surgical device also includes an adapter assembly having: a tubular housing having a proximal end portion configured to couple to the handle assembly, and a distal end portion; a second electrical connector disposed at the proximal end portion and configured to couple to the first electrical connector; an electrical contact assembly disposed at the distal end portion; and a wire harness disposed within the tubular housing and interconnecting the second electrical connector and the electrical contact assembly. The surgical device also includes a surgical end effector configured to couple to the distal end portion of the adapter assembly, the surgical end effector includes an electrical contact configured to couple to the electrical contact assembly.

Surgical stapler adapter with flexible cable assembly, flexible fingers, and contact clips

An adapter assembly includes an elongated body, a switch, a sensor link, 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 switch is configured to be toggled in response to the surgical loading unit being coupled to the distal portion of the adapter assembly. The sensor link is disposed within the distal portion of the adapter assembly and biased toward a distal position. The sensor link is longitudinally movable between a proximal position and the distal position. The annular member is disposed within the distal portion and is rotatable between a first orientation, in which the annular member prevents distal movement of the sensor link, and a second orientation, in which the sensor link moves distally to toggle the switch.

Adapter assemblies for interconnecting surgical loading units and handle assemblies

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.

Adapter assemblies selectively interconnect a surgical end effector that is configured to perform at least a pair of functions and a surgical device that is configured to actuate the end effector. The adapter assembly includes an adapter knob housing configured and adapted for connection with the surgical device and to be in operative communication with each of the at least one rotatable drive shaft of the surgical device. The adapter knob housing defines a lumen extending longitudinally therethrough and a ring gear formed in an inner surface of the lumen of the adapter knob housing. The ring gear defines an internal array of gear teeth which are engaged with a spur gear of a rotatable drive shaft. The adapter knob housing may be a unitary member and may be formed of plastic.

Surgical adapter assemblies for use between surgical handle assembly and surgical end effectors

An adapter assembly selectively interconnects a surgical end effector that is configured to perform at least a pair of functions and a surgical device that is configured to actuate the end effector. The end effector includes a first axially translatable drive member and a second axially translatable drive member. The surgical device includes a first rotatable drive shaft and a second rotatable drive shaft.
