  • Patent number: 11951688
    Abstract: A generator injection tool is provided. The generator injection tool injects an adhesive into a generator that includes a rotor positioned within a stator having a stator vent, the stator and rotor having a gap therebetween. The generator injection tool includes a first carriage sized to fit within the gap, a tube, a first motor, a controller, and an adhesive source. An end of the tube is movable between a first position in which the end is outside of the stator vent and a second position within the stator vent. The first motor is operable to move the tube between the first position and the second position. The controller is operable to selectively activate the first motor to position the end of the tube within the stator vent. The adhesive source moves the adhesive through the tube end to inject a portion of the adhesive into the stator vent.

  • Publication number: 20240092267
    Abstract: A vehicular interior rearview mirror assembly includes a mirror head pivotally adjustable about a mirror support. The mirror head includes a video display device disposed rearward of a prismatic mirror reflective element having a transflective mirror reflector. A touch sensor is disposed at the prismatic mirror reflective element and is associated with circuitry at a flexible printed circuit of the video display device. The video display device is operable to display video images captured by a rearward viewing camera of the vehicle. Light emitted by the video display device passes through the transflective mirror reflector for viewing of displayed video images by the driver of the vehicle viewing the prismatic mirror reflective element. The reflective region of the transflective mirror reflector of the prismatic mirror reflective element reflects at least 40 percent of visible light incident at the front side of the prismatic mirror reflective element.

  • Publication number: 20240041523
    Abstract: An end effector assembly for an optical surgical instrument includes a jaw member and a plurality of optical elements positioned within a cavity of the jaw member. The jaw member has a tissue contacting surface. The jaw member has a proximal portion that is configured to secure a fiber optic cable thereto such that a distal end of the fiber optical cable extends into the cavity. The plurality of optical elements are arranged in a staircase-like manner that rises towards the tissue contacting surface as the plurality of optical elements extends distally within the cavity. The plurality of optical elements is configured to direct a beam of light exiting the fiber optic cable towards the tissue contacting surface.

  • Patent number: 11547466
    Abstract: A surgical device includes a handle assembly, an elongated portion, an end effector, a visualization device, and a constant horizon mechanism. The elongated portion extends distally from the handle assembly and defines a longitudinal axis. The end effector is rotatable about the longitudinal axis relative to the handle assembly. The visualization device defines a visualization axis. A first portion of the visualization device extends through the elongated portion, and a second portion of the visualization device is disposed at least partially within the handle assembly. The visualization device is rotatable about the longitudinal axis relative to the handle assembly. The constant horizon mechanism is disposed in operative engagement with the visualization device and is configured to prevent the visualization device from rotating about the visualization axis when the visualization device rotates about the longitudinal axis.

  • Patent number: 11000308
    Abstract: The present disclosure is directed to a fluid cooled ultrasonic surgical instrument and related systems and methods of use therefor. In some embodiments, the disclosed ultrasonic surgical instrument is adapted for used within an insufflated cavity or pneumoperitoneum of a patient. The instrument includes a housing having an elongate shaft, a waveguide disposed at a distal end of the shaft, a coolant inlet port defined in an outer surface of the housing, and a coolant pump disposed within the housing and configured to move coolant from the coolant inlet port to the waveguide. During use, insufflation gas from within the pneumoperitoneum is drawn into the instrument shaft by the coolant pump, and blown over the waveguide to provide cooling. The delivery of ultrasonic energy and activation of the pump may be controlled by a processor in response to user input and waveguide temperature.
