A yoke for a suspension system for a medical lamp comprises a rigid yoke member having a first end and a second end, a first revolving joint-component fixed to the first end, wherein the first revolving joint has a first rotation axis, and a second revolving joint-component fixed to the second end, wherein the second revolving joint has a second rotation axis. The first rotation axis is included in a plane and the second rotation axis intersects the plane or is included in the plane, and the first rotation axis and a projection, onto the plane, of the second rotation axis intersecting the plane or the second rotation axis included in the plane enclose an angle (?) of more than 0 degrees and less than 90 degrees.

Disclosure herein are aerodynamic surgical lights and methods of manufacturing and use thereof. The aerodynamic surgical lights may include a light head made of one or more substantially tubular light housings. The substantially tubular light housings contain and protect a plurality of LED lights and their respective reflectors that aim a light beam toward the lower side of the substantially tubular light housings. The substantially tubular light housings are vertically elongate. The vertically elongated substantially tubular light housings include upper sections that are aerodynamically curved or pointed to streamline airflow past the light housings. The upper sections of the substantially tubular light housings are made of molded plastic resin reinforced with carbon fibers or glass fibers and the lower sections of the substantially tubular light housings are made of a clear moldable plastic.

A surgical light including a light housing having at least one light source therein and a handle assembly extending from the light housing, with the handle assembly including a knob and a cover. The handle assembly is rotatably connected to the light housing. The cover covers the knob. Engaging the cover in a first mode and rotating the knob alters a first characteristic of light emitted from the at least one light source. Engaging the cover in a second mode and rotating the knob alters a second characteristic of light emitted from the at least one light source.

Disclosure herein are aerodynamic surgical lights and methods of manufacturing and use thereof. The aerodynamic surgical lights may include a light head made of one or more substantially toroidal light housings. The substantially toroidal light housings contain and protect a plurality of LED lights and their respective reflectors that aim a light beam toward the lower side of the substantially toroidal light housings. The substantially toroidal light housings are vertically elongate. The vertically elongated substantially toroidal light housings include upper sections that are aerodynamically curved or pointed to streamline airflow past the light housings. The upper sections of the substantially toroidal light housings are made of molded plastic resin reinforced with carbon fibers or glass fibers and the lower sections of the substantially toroidal light housings are made of a clear moldable plastic.

A surgical lighting system includes a central shaft, a surgical light head, an extension arm, a load balancing arm, and a yoke assembly. The extension arm is pivotably mounted to the central shaft. The load balancing arm is pivotably mounted to the extension arm. The yoke assembly supports the light head for multi-axis movement relative to the load balancing arm. The surgical light head includes a plurality of light emitting elements that are arranged to emit light downward to a region of interest and an optical signal generating component configured to capture data associated with the region of interest and generate an optical signal based on the captured data. Optical fiber cables and rotatable joints transmit the optical signal associated with the captured data from the surgical light head to one or more of the yoke assembly, the load balancing arm, the extension arm, and the central shaft.

This disclosure relates to a surgical lighting device comprising a shell (12), a plurality of light sources (24) coupled to the shell, and a closure plate (18) for closing the lighting device by allowing light to pass through. The closure plate comprises a plurality of lens elements, each lens element being configured to collect and focus light from a corresponding light source to generate a light spot of a predetermined diameter located at a predetermined distance from the lighting device. In order to simplify the structure of the lighting device, the light sources and the cover plate are arranged in such a way that the light beams coming from the light sources and received by the associated lens elements arrive at the lens elements without substantial reflection or deflection. The closure plate therefore comprises all the optics necessary for collecting and focusing the light from the light sources.

An illumination device (100) includes an illumination unit (1, 2) which illuminates a surface (Ob). The position and the orientation of the illumination unit (1, 2) relative to the surface (Ob) can be changed. A distance sensor (4.1, 8.2) measures an indicator of the current distance between the illumination unit (1, 2) and the surface (Ob). A signal processing control unit (10) is configured to control an output unit (6.1, 6.2) of the illumination unit (1, 2). The controlled output unit (6.1, 6.2) outputs an indication of how much the measured distance deviates from a predetermined reference distance (Ref.sub.1, Ref.sub.2).

A yoke for a suspension system for a medical lamp comprises a rigid yoke member having a first end and a second end, a first revolving joint-component fixed to the first end, wherein the first revolving joint has a first rotation axis, and a second revolving joint-component fixed to the second end, wherein the second revolving joint has a second rotation axis. The first rotation axis is included in a plane and the second rotation axis intersects the plane or is included in the plane, and the first rotation axis and a projection, onto the plane, of the second rotation axis intersecting the plane or the second rotation axis included in the plane enclose an angle () of more than 0 degrees and less than 90 degrees.

A handle assembly for an accessory of a medical device support system. The handle assembly includes a handle, an interface device, a conductive coating, and a connector. The interface device is in an outer surface of a generally tubular section of a handle housing of the handle and is configured to receive an input or transmit an output associated with the medical device support system. The conductive coating is on the inner surface of the generally tubular section and is configured to transmit one or more of power, ground, control signals, and communication signals corresponding to the input or the output of the interface device. The connector is connected to the conductive coating and is configured to transmit the one or more of the power, ground, control signals, and communication signals from the conductive coating to another part of the accessory and/or the medical device support system.

The present invention relates to a system for monitoring a surgical luminaire assembly comprising at least one surgical luminaire, with a monitoring unit. It is provided here that the system comprises a 3D sensor which three-dimensionally detects the surgical luminaire assembly and/or an operating area arranged below the surgical luminaire assembly, wherein the data of the 3D sensor are evaluated by the monitoring unit with respect to the surgical luminaire assembly.
