  • Publication number: 20140246477
    Abstract: A joy stick control assembly for operating a motor driven surgical instrument. In at least one form, the joystick control assembly comprises a first switch assembly that is movably supported by a housing. The first switch assembly may include a joystick that is movably mounted thereto such that pivotal movement of the joystick relative to the first switch assembly causes at least one corresponding control signal to be sent to at least one motor communicating therewith. The joystick control assembly may further include a second switch assembly that comprises a first sensor and a second sensor that is movable with the first switch assembly such that movement of the second sensor relative to the first sensor causes at least one other control signal to be sent to another one of the surgical instrument motors.

  • Publication number: 20140249557
    Abstract: A thumbwheel control assembly operably supported on the handle assembly of a motor powered surgical instrument. The thumbwheel control assembly communicates with a motor in the handle such that when an actuator portion of the thumbwheel control assembly is pivoted in a first direction, the motor applies a rotary motion to one of an elongate shaft assembly and an end effector coupled thereto in the first direction and when the actuator portion is pivoted in a second direction, the motor applies the rotary motion to one of the elongate shaft assembly and end effector in the second direction.

  • Publication number: 20140246479
    Abstract: In various forms, a sensor-straightened end effector is disclosed. The sensor-straightened end effector may comprise an end effector coupled to a shaft at an articulation point. The end effector may be articulable at an angle with respect to the shaft. A sensor may be disposed on the sensor-straightened end effector, such as on the shaft or on the end effector. The sensor is configured to detect a gross proximal movement. When detecting a gross proximal movement, the sensor may generate a signal to control a motor to begin a straightening process to straighten the end effector with respect to the shaft.

  • Publication number: 20140246476
    Abstract: 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.

  • Publication number: 20140246474
    Abstract: A surgical instrument configured to relay a low-power signal from an end effector to a remote device is disclosed. The surgical instrument may comprise a handle, a shaft extending distally from the handle, and an end effector attached to the distal end of the shaft. A sensor may be disposed in the end effector. The sensor may generate a signal indicative of a condition at the end effector. A transmitter may be located in the end effector. The transmitter may transmit the signal from the sensor at a first power level. The signal may be received by a relay station located proximally to the shaft. The relay station is configured to retransmit the signal at a second power level, wherein the second power level is higher than the first power level.

  • Patent number: 8295706
    Abstract: A technique for simultaneously transmitting wide and narrow optical beacon signals includes generating a laser beam and splitting the laser beam into a first signal on a first path and a second signal on a second path via a wavelength-dependent beamsplitter. A wide beacon signal having a first beam divergence is generated from the first signal, and a narrow beacon signal having a second, lesser beam divergence is generated from the second signal. The wavelength of the laser beam determines an allocation of the laser energy between the wide and narrow beacon signals based on transmittance/reflectance characteristic of the beamsplitter at that wavelength. The wide and narrow beacon signals are simultaneously transmitted in a overlaid manner into free space to support acquisition and tracking in a free-space optical communication system. The beamsplitter can simultaneously transmit or reflect substantially all of a data signal at a different wavelength.
