An adapter for a disposable medical scope device includes a body configured to be removably attached to a scope device. The adapter includes at least one button including an actuator configured to activate at least one circuit within a scope device to which it is attached. The body is configured to be electrically coupled to a control unit such that, when the circuit is activated by the button, a signal is sent from the adapter to the control unit to control the control unit's handling of output from the scope device.
