Various embodiments are directed to a powered surgical instrument for cutting and fastening tissue. The instrument may comprise an end effector comprising a first jaw member and a second jaw member. The second jaw member may be coupled to move relative to the first jaw member from an open position, where the jaw members are apart from one another, to a closed position. The end effector may also comprise a firing bar positioned to fire by translating within the end effector when the first and second jaw members are in the closed position. Additionally, the surgical instrument may comprise a drive device, a clamping trigger and a control circuit. The drive device may be mechanically coupled to the firing bar. The clamping trigger may be mechanically coupled to the end effector such that actuation of the clamping trigger causes the second jaw member to pivot towards the first jaw member. The control circuit may comprise a firing switch, a clamp switch, a latching device and an end-of-stroke sensor. The firing switch may be configured to be in electrical communication with a power supply for powering the drive device and in electrical communication with the drive device. The clamp switch may be in mechanical communication with the clamping trigger. The latching device may be in electrical communication with the clamp switch, the power supply and the drive device. The end-of-stroke switch may be in electrical communication with the latching device. Additionally, the firing switch may be electrically connected to, upon actuation, connect the power supply to the drive device via a first connection comprising the latching device and the firing switch. Further, the end-of-stroke switch may be electrically connected to, upon sensing an end of a stroke of the firing bar, cause a change in a state of the latching device to break the first connection between the power supply and the drive device.

Surgical instrument having a power control circuit

A surgical instrument includes a drive member movable by a drive motor between a home position and an end of stroke. A mechanical stop is disposed at or near the end of stroke and is structured to increase resistance to movement of the drive member from a first position to a second position. A control system detects a current spike associated with the increased resistance and interrupts power to the drive motor.

Surgical instrument soft stop

A portable linear fastener driving tool is provided that drive staples, nails, or other linearly driven fasteners. The tool uses a gas spring principle, in which a cylinder filled with compressed gas is used to quickly force a piston through a driving stroke movement, while a driver also drives a fastener into a workpiece. The piston/driver is then moved back to its starting position by use of a rotary-to-linear lifter, and the piston again compresses the gas above the piston, thereby preparing the tool for another driving stroke. The driver has protrusions along its edges that contact the lifter, which lifts the driver during a return stroke. A pivotable latch is controlled to move into either an interfering position or a non-interfering position with respect to the driver protrusions, and acts as a safety device, by preventing the driver from making a full driving stroke at an improper time.

Fastener driving tool using a gas spring

A surgical instrument. The surgical instrument has a force delivery system which communicates a changing force to a user of the surgical instrument when a limit of a surgical function is reached. A sensor senses position of a moving element to communicate a signal to the force delivery system. In various embodiments, the system generates a vibratory force to signal the user.

Surgical stapling instruments having surgical stapling cartridges are disclosed. At least one embodiment includes an end effector that has an elongate channel that is configured to operably support a surgical staple cartridge therein and an anvil that is movably supported on the elongate channel between an open position and closed positions in response to an application of opening and closing motions applied thereto. An anvil lock member cooperates with the anvil to retain the anvil in an open position when a staple cartridge has not been installed in the elongate channel and prevent the anvil from moving to a closed position until the staple cartridge has been seated within the elongate channel. Surgical staple cartridges are configured to move the anvil from an open position to an actuatable position when the cartridge has been installed in the end effector.
