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 method and device for controlling the compression of tissue include clamping tissue between a first clamping member and a second clamping member by driving at least one of the clamping members with an electric motor toward a predetermined tissue gap between the clamping members and, during the clamping, monitoring a parameter of the electric motor indicative of a clamping force exerted to the tissue by the clamping members. The method and device include, during the clamping, controlling the electric motor, based on the monitored parameter, to limit the clamping force to a predetermined maximum limit.

A surgical instrument comprising a first iaw, a second iaw, a staple cartridge, a firing system, an electric motor, a power source, a regulator, and a control system is disclosed. The first iaw is movable relative to the second iaw to capture tissue between the first iaw and the second iaw. The staple cartridge is supported by the second iaw and comprises staples removably stored therein. The firing system is configured to drive the staples toward the first jaw. The electric motor is mechanically coupled to the firing system. The power source is electrically couplable to the electric motor. The regulator is electrically connected to the power source and the electric motor. The control system is electrically connected to the regulator. The control system is configured to control a speed of the electric motor based on a voltage set point of the regulator.

A surgical staple and staple cartridge for removably storing the surgical staple. The surgical staple can comprise a plurality of separate and discrete staple drive surfaces. The staple drive surfaces can be configured to move along parallel paths in the staple cartridge. Additionally, the staple cartridge can comprise a staple cavity, and a plurality of lift planes can extend through the staple cavity.

A surgical instrument can comprise a handle, a motor, and a shaft extending from the handle. The handle and/or the shaft can define a longitudinal axis. The surgical instrument can further comprise a fastener cartridge comprising a plurality of fasteners removably stored therein, an anvil configured to deform the fasteners, a closure drive configured to move the anvil toward and away from the fastener cartridge which is rotatable about the longitudinal axis, and a firing drive configured to deploy the fasteners from the fastener cartridge which is rotatable about the longitudinal axis. The surgical instrument can further comprise a transmission comprising a first operating configuration which connects the motor to the closure drive and a second operating configuration which connects the motor to the firing drive.

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.

The present disclosure discloses a stapling device, comprising an activation unit configured to sense at least one of a movement of the stapling device, a position of a switch or a signal from a timer. There is a detection unit that is activated based on a signal from the activation unit to generate an input data. The stapling device further comprises a processing unit to determine number of pins in the stapling device, by comparing the input data with a pre-configured data and a display unit interfaced with the processing unit, to indicate status of the pins in the stapling device, wherein the status is based on the determined number of pins in the stapling device. Thus the stapling device of the present disclosure identifies the exhaustion of pins and accordingly enables timely replenishment of the stapling device with pins.

A surgical instrument comprises an end effector, a shaft, and a housing extending proximally from the shaft. The surgical instrument includes an articulation assembly configured to articulate the end effector relative to the shaft, a firing assembly configured to fire a plurality of staples, for example, and a locking member movable between a locked configuration and an unlocked configuration. The housing is removably couplable to the shaft when the locking member is in the unlocked configuration and the housing includes a motor configured to drive at least one of the firing assembly and the articulation assembly. The housing also includes a controller in communication with the motor, wherein the controller is configured to activate the motor to reset at least one of the firing assembly and the articulation assembly to a home state when the locking member is moved between the locked configuration and the unlocked configuration.

A surgical instrument system is disclosed. The surgical instrument system comprises a proximal end, a distal end, a first jaw, and a second jaw. The first jaw is movable relative to the second jaw to capture tissue. The surgical instrument system further comprises a sensor system configured to sense the impedance of the tissue at a plurality of discrete locations, a staple cartridge comprising staple cavities, staples removably stored in the staple cavities, an anvil, a firing system configured to move the staples toward the anvil, an electric motor configured to move the firing system toward the distal end during a firing stroke, and a control system. The control system is configured to evaluate the impedance of the tissue at the discrete locations and control the power applied to the electric motor during the firing stroke as the firing system moves relative to the discrete locations.

A surgical instrument is disclosed. The surgical instrument comprises a first jaw, a second jaw, a staple cartridge, a firing system, an electric motor, a power source, and a control system. The first jaw is movable relative to the second jaw to capture tissue between the first jaw and the second jaw. The staple cartridge is supported by the second jaw and comprises staples removably stored therein. The firing system is configured to drive the staples toward the first jaw. The electric motor is mechanically coupled to the firing system. The power source is electrically couplable to the electric motor. The control system is electrically connected to the power source. The control system is configured to determine a first level of power supplied by the power source and apply a second level of power to the electric motor if the first level of power exceeds a predetermined threshold. The second level of power is lower than the first level of power.
