ABSTRACT:
A body cavity diagnostic apparatus which is applied to an ultrasonic probe or an endoscope inserted into a cavity of a patient's body. The main body of the apparatus is electrically isolated from the patient completely. Two insulating covers are placed over a structural member in such a manner as to overlap each other at the connecting portion for a bent portion and an operating portion. An annular airtight member such as an O ring, or an annular protrusion integrally provided with the inner insulating cover is provided between the two insulating covers in order to prevent the ingress of a fluid. An insulating member is provided between an electrically conductive member of the insert portion and a base plate for a support shaft of the operating portion. Operating wires are connected to each other by a joint member of an insulating material, thereby electrically isolating the operating portion from the bent portion.
