ABSTRACT:
An ultrasonic diagnosis device disclosed includes an endoscope with an ultrasonic diagnosis function, wherein an ultrasonic probe is arranged in the front end region of the portion to be inserted into a coelom or the like cavity, and is connected to an external rotational drive portion by a hollow multi-layered power transmission means to provide an observation field extending through the entire angular range. Signal wires from the probe and passed between outer and inner layers of the power transmission means which thus has a hollow center channel. Preferably, an observation optical system is arranged within the hollow channel to provide a visual field on the front side in the insertion direction, for a continuous confirmation purpose, permitting the insertion portion to be safely inserted even into a narrow cavity of an organ with a complex undulation.
