Patent ID: 8376950

Claim:
An ultrasonic endoscope to be used when connected to an ultrasonic endoscopic apparatus main body, said ultrasonic endoscope comprising: an ultrasonic transducer part having plural ultrasonic transducers configured to transmit and receive ultrasonic waves; a flexing part that is flexible and configured to support said ultrasonic transducer part; an operation part configured to be connected to said ultrasonic endoscopic apparatus main body via at least one cord; a coupling part configured to couple said flexing part to said operation part; a covering material configured to cover at least said flexing part and said coupling part; a first heat-conducting member having one of a foil shape, a wire shape, a mesh shape, and a sheet shape, and provided inside of said covering material and extended to a part of said operation part while being in contact with said covering material to transfer heat generated in said ultrasonic transducer part to said operation part; plural angle rings configured of a high heat-conducting material, plural fixing parts configured to fix said plural angle rings to said first heat-conducting member, and plural pins configured to connect said plural angle rings to one another to be relatively displaced; and a second heat-conducting member having one end directly fixed to a side surface of the ultrasonic transducer part, and the other end directly fixed to one of said plural angle rings, said second heat-conducting member transferring the heat generated in said ultrasonic transducer part to said first heat-conducting member via said plural angle rings and said plural fixing parts.
