A detachable motor-powered surgical instrument. The instrument may include a housing that includes at least one engagement member for removably attaching the housing to an actuator arrangement. A motor is supported within the housing for supplying actuation motions to various portions of a surgical end effector coupled to the housing. The housing may include a contact arrangement that is configured to permit power to be supplied to the motor only when the housing is operably attached to the actuator arrangement.

A surgical instrument configured to be coupled to a robotic surgical system is disclosed. The surgical instrument comprises an end effector, a threaded drive shaft, a firing member drivable by the threaded drive shaft, a closure system configured to move a iaw of the end effector toward a closed position, and a housing assembly coupleable with the robotic surgical system and comprising an array of electrical contacts. The surgical instrument further comprises a first motor configured to drive the closure system, a second motor configured to drive the threaded drive shaft, a first decoupleable electrical contact configured to supply power to the first motor from a power system, and a second decoupleable electrical contact configured to supply power to the second motor from the power system. The power system is selectively interrupted unless a signal is provided to the power system from the robotic surgical system.

A stapling instrument for use with a surgical robot is disclosed. The stapling instrument comprises an interface including a plurality of rotary members, a shaft rotatable about a longitudinal axis by a first rotary member, an end effector rotatably connected to the shaft about an articulation joint, an articulation cable, a coupling member, and a firing cable. The end effector comprises a first jaw, a second jaw, and a staple cartridge comprising staples. The articulation cable operably connects to a second rotary member and is operable to pull the articulation cable and articulate the end effector. The coupling member is movable through a first stroke to move the second jaw toward the first jaw and movable through a second stroke to fire the staples. The firing cable operably connects to a third rotary member and is operable to drive the coupling member through the first stroke and the second stroke.

A weight balance method of a surgical microscope is able to automatically align, in response to a switching operation, a center of gravity G of the surgical microscope 5 with a rotary shaft S. A weight balance of the surgical microscope is easily attained only by slanting the surgical microscope, and therefore, no part of the surgical microscope protrudes upward to interfere with a supporting structure of the surgical microscope.

A surgical device comprising a first clamping member, a second clamping member, an electric motor, and a control system is disclosed. The electric motor is configured to drive at least one of the first clamping member and the second clamping member toward a predetermined tissue gap between the first clamping member and the second clamping member to clamp the tissue of a patient. The control system is configured to monitor a parameter of the electric motor. The parameter is indicative of a clamping force exerted to the tissue by the first clamping member and the second clamping member. The control system is further configured to control the electric motor based on the parameter to limit the clamping force to a predetermined maximum limit.
