Abstract: A signal adapter device for interfacing a medical camera with a processing device is disclosed. The signal adapter device comprises a first interface configured to receive video signals from a medical camera and a second interface configured to transmit converted signals to a processing device. A processing unit converts video and control signals between different formats. The signal adapter device includes a mechanical locking mechanism at the second interface to prevent unintentional disconnection, while allowing the first interface to remain freely detachable. The housing incorporates thermal management structures to dissipate heat from internal components and, optionally, from the connected camera. The signal adapter device may further regulate power supplied to the camera, with optional electrical isolation.
