Abstract
Ultrasonic endoscope equipment transmits signals by providing a signal coupler such as rotary transformer or optical coupling device without using the signal line between the rotating part which introduces a signal line from an ultrasonic transducer housed in a rotatable way in the end of the inserting part of the endoscope and outputs the ultrasonic high frequency signal via a preamplifier and an ultrasonic image display unit which receives the ultrasonic high-frequency signal output from the rotating part and displays an ultrasonic image, the primary input side being provided on the output side of the said rotating part and the secondary output side on the input side of the said ultrasonic image display unit.
