ENDOSCOPE HAVING AN ULTRASONIC DIAGNOSIS FUNCTION

摘要

An endoscope having an ultrasonic diagnosis function, comprises a distal end including an observing portion connected to a flexible tube, and provided with a view window and an illumination window formed on one surface thereof; an ultrasonic wave emitting-receiving portion located on the tip side of the observing portion aligned with the observing portion and provided with an ultrasonic oscillator having an ultrasonic wave emitting and receiving plane parallel with the view window; and a parallel moving link mechanism for moving the ultrasonic wave emitting-receiving portion such that it is moved away from the observing portion with the ultrasonic wave emitting-receiving plane kept substantially parallel with the view window.
