Medical visualization devices and systems

A medical visualisation system comprising:

• a main component including an image sensor and a light emitter, the main component being configured to sense a view with the image sensor;
• a first auxiliary component configured to physically couple and decouple with the main component and, if coupled to the main component, transmit image data based on the view, the first auxiliary component comprising a controller, a first memory, a high frequency wireless transceiver, a short-range communication circuit, and a first rechargeable battery;
• a second auxiliary component configured to physically couple and decouple with the main component and, if coupled to the main component, transmit image data based on the view, the second auxiliary component comprising a controller, a second memory, a high frequency wireless transceiver, a short-range communication circuit, and a second rechargeable battery, the second memory having embedded therein data;
• and
• a video processing apparatus comprising a high frequency wireless transceiver configured to establish an image data communication channel with the high frequency wireless transceiver of the first auxiliary component or with the high frequency wireless transceiver of the second auxiliary component and to receive the image data via the image data communication channel,
• wherein the first auxiliary component is configured to, based on the data, cause adjustment of one or more components of (a) the main component and/or (b) the video processing apparatus.
