  • Patent number: 11872088
    Abstract: A surgical light head and proximity detection method includes a housing, a plurality of light emitting elements arranged in the housing and configured to direct light at a target region of interest, and a plurality of distance sensors arranged in the housing. At least two of the distance sensors have field of views that overlap to define a common detection region of interest and the common detection region of interest at least partially overlaps with the target region of interest. The light head may have a plurality of integrally formed tilted seats that position the distance sensors relative to a center line of focus of the surgical light head. The distance sensors may be integrated in the housing via an optical component that is sealed relative to the housing and covers the distance sensor while enabling transmission and receipt of distance sensing signals therethrough.

  • Publication number: 20230355343
    Abstract: A sterilizable cover for a handle of an accessory of a medical suspended ceiling assembly includes a generally tubular stem portion and an annular flange portion. The generally tubular stem portion has a sufficient size to be gripped by the human hand, and has a proximal end that is open and a distal end that is closed, and defines a cavity along a longitudinal axis for receipt therein of a handle grip portion. The generally tubular stem portion includes a friction fit portion that is configured to flex radially outwardly to create a friction fit with a portion of the handle grip portion upon receipt of the handle grip portion in the cavity of the generally tubular stem portion. The annular flange portion extends radially outwardly from a proximal end of the generally tubular stem portion. The generally tubular stem portion and the annular flange portion are a single continuous piece of flexible silicone rubber.

  • Publication number: 20230248248
    Abstract: A surgical lighting system includes a surgical lighthead including a lighthead housing including one or more light emitting elements therein that are arranged to emit light toward a region of interest. In some embodiments a temperature sensor is mounted to the lighthead housing and arranged such that it measures the temperature of a location in the region of interest. In other embodiments, a temperature sensor is external to the lighthead and configured to measure the temperature of a location in the region of interest. A controller is operatively coupled to the temperature sensor and configured to control temperature at the region of interest based at least in part on the temperature measured by the temperature sensor.

  • Publication number: 20230248466
    Abstract: A system includes a surgical lighthead including a lighthead housing including a plurality of light emitting elements therein that are arranged to emit light toward to a region of interest, and a handle attached to the lighthead housing. A sensor is integrated with the lighthead and configured to measure an ambient environmental condition at the lighthead. In other embodiments, a medical device support system includes a support and an ambient environmental condition sensor assembly coupled to the support column and including a sensor configured to measure an ambient environmental condition at the ambient environmental condition sensor assembly. A controller is operatively coupled to the sensor and configured to detect an ambient environmental condition based at least in part on the measured ambient environmental condition by the sensor.

  • Patent number: 11703197
    Abstract: A lighting assembly includes a light transmissive substrate extending along a length and including a light emission portion including opposed first and second major surfaces spaced apart from one another in a thickness direction, an inner edge surface extending between the first and second major surfaces in the thickness direction, and an outer edge surface opposed the inner edge surface and extending in the thickness direction. An extension portion extends from the light emission portion proximate the second major surface in the thickness direction. A light source is attached to the extension portion. A light head includes a housing, a primary light source attached to the housing, and the lighting assembly as an auxiliary lighting assembly. The housing includes a channel in which the auxiliary lighting assembly is retained.

  • Patent number: 11680697
    Abstract: A light head for a medical device support system. The light head includes a housing base, an annular shape first lens, a housing cover, and a motion transfer member. The housing cover includes a cavity within which the annular shape first lens is rotatable about a rotation axis. The housing cover includes a second lens. The annular shape first lens and the second lens are in a light emitting path of the plurality of light emitting elements. The motion transfer member is configured to movably interact with a boss of the annular shape first lens to rotate the annular shape first lens about the rotation axis and within the cavity. A periphery of the annular shape first lens includes guide members configured to position the boss of the annular shape first lens to movably interact with the motion transfer member.

  • Publication number: 20220133431
    Abstract: A load balancing arm for a medical device support system includes a proximal hub, a support arm, a link, and a distal end vertical block. The components together may form a four bar linkage. The proximal hub is configured for pivotable movement about an axis P-P. The distal hub is configured to support a medical device load for pivotable movement about an axis D-D. The distal hub is mounted to the distal end vertical block for pivotable movement between a first position in which the axis D-D is at a first angle relative to the axis P-P and a second position in which the axis D-D is at a second angle relative to the axis P-P, wherein the first angle is different than the second angle. A parallelism adjustment mechanism enables the axis D-D to be adjusted so as to be substantially parallel to the axis P-P.
