  • Patent number: 9597074
    Abstract: A surgical stapler has a body, a shaft assembly extending distally from the body, and an end effector coupled with a distal end of the shaft assembly. The end effector has a stapling head assembly, an anvil, and a vacuum port. The vacuum port is operable to draw tissue between the stapling head assembly and the anvil. The anvil is operable to move toward and away from the stapling head assembly to thereby capture the tissue drawn between the stapling head assembly and the anvil. The stapling head assembly comprises a plurality of wheel assemblies and staple cartridges. At least one wheel assembly is operable to rotate to thereby move the anvil toward and away from the body. The remaining wheel assemblies are operable to rotate to thereby drive staples through the captured tissue. The body includes user input features operable to drive the wheel assemblies.

  • Patent number: 9326770
    Abstract: A surgical fastening instrument is disclosed. The instrument comprises an end effector cartridge assembly, a handle, and a firing member, wherein an electric motor is configured to impart a firing motion to the firing member to eject fasteners from a fastener cartridge of the end effector cartridge assembly. The instrument further comprises an electronic lockout system configured to ascertain whether the fastener cartridge is present in the end effector, permit the motor to apply the firing motion to the firing member when the presence of the fastener cartridge has been ascertained, and prevent the motor from applying the firing motion to the firing member when the presence of the fastener cartridge has not been ascertained.

  • Patent number: 9282966
    Abstract: A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector. In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel slot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing. Forming the E-beam from a thickened distal portion and a thinned proximal strip enhances manufacturability and facilitates use in such articulating surgical instruments.

  • Patent number: 9241758
    Abstract: An apparatus comprises a body, a shaft, an end effector, and a firing beam. The shaft extends distally from the body. The end effector is positioned at the distal end of the shaft. The end effector comprises a first jaw and a second jaw, with the first jaw being pivotable toward the second jaw. The firing beam is operable to translate relative to the end effector to thereby drive the first jaw toward the second jaw. The firing beam includes a deformable portion operable to deform in response to a stress imposed by the end effector on the firing beam as the jaws clamp on dense or thick tissue. The deformable portion is defined in part by a cutout. A compliance restriction feature restricts deformation in the firing beam. A resilient member biases the firing beam to a non-deformed configuration.

  • Patent number: 9244524
    Abstract: A surgical instrument includes an end effector, a manipulation unit, a grip detecting unit, a driving unit, and a control unit. When the control unit determines that the end effector is applying the acting force to the target based on the information acquired by the grip detecting unit, the control unit sets an acting force increasing zone of a predetermined range in a first movable range in the first direction of the manipulation unit, sets a neutral zone in a remaining area of the first movable range, controls the driving unit so that the acting force increases with a constant gradient with respect to an amount of manipulation of the manipulation unit in the acting force increasing zone, and controls the driving unit so that the acting force is kept constant regardless of the amount of manipulation of the manipulation unit in the neutral zone.

  • Patent number: 9226750
    Abstract: Systems and methods are provided for detecting failure in clamping of a material and/or firing of a staple into a clamped material and indicating such failure to a user on a user interface. The system and methods are particularly suited for use with end effectors having closing and/or firing mechanisms coupled to an actuator. By monitoring a driving parameter of an actuator that effects the clamping and/or firing, the systems and methods provide an indication of failure in response to the monitored drive parameter. In some embodiments, an indication of failure is output when the monitored drive parameter is outside an acceptable range of desired driving parameters during clamping and/or firing. The disclosed systems and methods are particularly beneficial when used for minimally invasive surgery.
