Abstract:
An endoscope (5300) for removing tissue at a surgical site includes an elongated tubular body insertable within a mammalian cavity of a patient. An instrument channel extends between a first opening at a distal end and a second opening at a proximal end of the tubular body and is sized and configured to receive a surgical cutting assembly (6120) that includes an aspiration channel configured to remove material entering the endoscope via a distal end of the surgical cutting assembly. A torque generation component configured to generate torque is positioned within the distal end and configured to provide the generated torque to a coupling component. The coupling component (5350) is positioned at the distal end of the elongated tubular member and configured to actuate a cutting component (6140) of the surgical cutting assembly responsive to actuation of the torque generation component.

The articulating shaft may extend proximally from the end effector along a longitudinal axis and may comprise a proximal shaft member and a distal shaft member pivotably coupled at an articulation joint. The ultrasonic transducer assembly may comprise an ultrasonic transducer acoustically coupled to the ultrasonic blade. The ultrasonic transducer assembly may be positioned distally from the articulation joint.
Abstract:
A self contained motor-powered disposable loading unit (16) for use with a robotic system configured to generate control systems there¬ for. The disposable loading unit may contain a battery (526) that is retained in a disconnected position when the disposable loading unit is not in use and is moved to a connected position when the dispos¬ able loading unit is coupled to the robotic system to permit the motor (562) to be selectively powered thereby. Indicators may be support¬ ed on the disposable loading unit to indicate when the axial drive as¬ sembly thereof is in a starting position and an ending position. Anoth¬ er indicator may be provided to indicate when the anvil assembly is in a closed position.

Abstract:
In various embodiments, a surgical end effector is disclosed. The surgical end effector comprises a staple cartridge comprising a proximal end and a distal end. The staple cartridge is configured to be used to staple tissue within an optimal tissue thickness range. An anvil is movably coupled relative to the staple cartridge. A tissue thickness sensing module is located adjacent to the distal end of the staple cartridge. The tissue thickness sensing module comprises a sensor and a controller. The sensor is configured to generate a tissue thickness signal indicative of a thickness of the tissue located between the anvil and the staple cartridge. The controller is in signal communication with the sensor. The controller comprises means for identifying a staple cartridge type. The staple cartridge type and the thickness measurement are used to determine if the thickness of the tissue is within the optimal tissue thickness range.
Abstract:
A multi-layer, fiber-reinforced composite orthopaedic fixation device having a design selected based on a desired characteristic of the orthopaedic fixation device. The design may be selected according to a model of the device, the model defining design constraints, and the design may comprise a pattern of the fiber angle for each layer. The selection of a design may be analyzed using finite element analysis to determine whether the design will comprise the desired characteristic.
