发明名称 Ultrasonic diagnosis device
摘要 An ultrasonic wave diagnosis device includes an ultrasonic wave transmission/reception scanner disposed at a distal end of an insertion section and having an ultrasonic wave oscillator therein, and a balloon surrounding the scanner and inflated outwardly by supplying an ultrasonic wave propagation liquid medium. A recess is formed in part of a circumferential surface of the insertion section, in the vicinity of the balloon in which an observation optical system is disposed to have a field of sight toward the balloon.
