To disconnect the light 1, the connector 60 is rotated in the opposite direction and the connector component 57 is removed from electrical connector 51.

(41) In some embodiments, the light is provided in a system with the solid support 2 and clamp 3. In some embodiments, solid support 2 (FIG. 3) is a rigid metal or other material (e.g. rigid plastic or resin). In some embodiments, the solid support is a single straight tube or rod or other shape. In some embodiments, the solid support comprises one or more segments. In some embodiments, one or more of the segments is rigid or flexible. In some embodiments, one or more of the segments are straight or curved or another geometry. In some embodiments, the solid support 2 is shaped and dimensioned to position the light 1 in an ideal location within the surgical field, while eliminating or minimizing interference by either the light 1 or solid support 2 with the surgeon or other medical personnel or equipment.

(42) In some embodiments, the solid support is sterilizable (e.g., via autoclave). In some embodiments, the solid support attaches to a medical procedure surface. In some embodiments, the solid support is attaches to the medical procedure surface using clamp 3. In some embodiments, the medical procedure surface is a surgical bed (e.g., bed rail). In some embodiments, the height of the solid support is adjustable (e.g., via the clamp). For example, in some embodiments, the solid support slides through the clamp until the desired height is reached. The clamp is then tightened and the solid support is locked in place at the desired height.

(43) In some embodiments, systems comprise one or more software components (e.g. located on the solid support or lighting components, remotely, or a combination).

(44) In some embodiments, cameras and or microphones provided with the system survey the surgical environment and record useful information and/or provide useful feedback to the surgeon, the patient, or others. For example, in some embodiments, video and or sound information collected is sent to and evaluated by a remote user (or computer) and provides feedback to improve the procedure or to evaluate the procedure for after-procedure feedback. In some embodiments, the system monitors, via video or audio, the treating physician to identify signs of fatigue and provides a warning (e.g., alarm light or sound) to notify the physician that they should remain alert or take some other action (e.g., drink coffee, swap shifts with another physician, etc.).

(45) In some embodiments, one or more motors are provided with the system that control movement or positioning of one or more components of the system. In some embodiments, a motor is located at the lamp and positions the direction of the lamp. In some embodiments, a motor is located in the arm portion of the lighting component, at the juncture between the lighting component and the support arm, and/or at the junction of the support arm and the table or table rail. In some embodiments, the motors are remotely controlled to control the position of one or more portions of the system. In some embodiments, the motors are controlled by a foot pedal, joystick, or other external device. In some embodiments, the system comprises a body-tracking feature that detects an object in the room and moves the light in response to movement of the object. The object may be the physician's head (e.g., eyes) (e.g., identified by video capture, a fiducial located on the physician, etc.), arms, or hands or a medical device or a location on a patient. In some preferred embodiments, head tracking is employed such that the light moves to simulate lighting that would have been provided by a headlight worn by the physician. In some embodiments, system components are automatically moved to adjust for lighting quality, avoidance of shadows at the surgical site, or other desired optimizations. In some embodiments, remote components of the system communicate wirelessly, for example, using WiFi, Bluetooth, near-field communication technology, or other protocols.

(46) The devices and systems described herein find use in a variety of medical procedures. The lights find use in any medical procedure that utilizes a sterile field and detailed lighting. In some embodiments, the medical procedure is surgery, for example transplant surgery, although other surgeries and medical procedures are specifically contemplated.
