    Abstract: Aspects of the present disclosure include a surgical device comprising electrodes on the sides of an end of an effector to aide in sealing during various surgical procedures, such as a liver resection. During a sealing procedure, the surgeon may wipe the surgical site with the end effector, causing the electrodes to touch the fractured area. Electrosurgical energy may be applied to the electrodes during the wiping, causing coagulation of smaller vessels, such as tiny blood vessels and bile ducts in the parenchyma of the liver. In some cases, due to the nature of some smaller vessels, electrosurgical energy should be delicately applied to cause sealing but to avoid overly damaging the remaining tissue. In some embodiments, the thin design of the electrodes allows for an appropriate amount of electrosurgical energy to be applied to the fractured area.

    Abstract: A surgical stapler. The surgical stapler includes a drive system, an electric motor, a battery and a control system. The drive system includes an actuation member. The electric motor is mechanically coupled to the drive system. The battery is electrically couplable to the electric motor. The control system includes an H-bridge circuit electrically couplable to the electric motor. The control system is configured to control the electric motor based on a sensed parameter associated with the electric motor, a position of the actuation member and a velocity of the actuation member.

    Abstract: A modular shaft assembly is disclosed. The modular shaft assembly includes one or more inputs configured to receive input motions from a surgical instrument system, such as a handle, for example. The shaft assembly further includes one or more on-board inputs configured to generate input motions. The input motions received and generated by the shaft assembly are transferable to an end effector of the shaft assembly to perform various functions at the end effector. The end effector can include a staple cartridge and a firing member which is movable between a proximal position and a distal position to eject staples from the staple cartridge. The end effector can include a plurality of jaw members and the firing member can comprise camming members which are configured to position the jaw members relative to one another.

    Abstract: A surgical instrument has a staple cartridge housing a plurality of staples and an anvil configured to capture tissue therebetween. The surgical instrument also has a firing assembly configured to deploy the plurality of staples into the captured tissue during a firing sequence, and a handle that includes an electric motor operably coupled to the firing assembly, wherein the electric motor is configured to motivate the firing assembly to deploy the plurality of staples into the captured tissue during the firing sequence, and a power pack. The power pack includes rechargeable battery cells configured to power the electric motor, at least one battery-cell health indicator, and an electronic control circuit configured to assess whether a subset of rechargeable battery cells is damaged during the firing sequence based on at least one measurement performed by the at least one battery-cell health indicator.

    Abstract: A surgical system is disclosed including a motor cartridge and a drive assembly. The motor cartridge is removably positionable in an enclosure and removably couplable with the surgical system. The motor cartridge includes a first motor including a first drive shaft, a first motor control circuit in electrical communication with the first motor, a second motor including a second drive shaft, and a second motor control circuit in electrical communication with the second motor. The drive assembly is removably couplable with the motor cartridge. The drive assembly includes a first rotatable input configured to be driven by the first drive shaft, a second rotatable input configured to be driven by the second drive shaft, a first rotatable output configured to provide a first control motion, a second rotatable output configured to provide a second control motion, and a third rotatable output configured to provide a third control motion.
