Claims

[Scope of utility model registration request]

(1) An ultrasonic probe that transmits and receives ultrasonic waves is housed on the distal end side of a flexible tubular insertion part that can be inserted into a body cavity, etc., and the ultrasonic probe has a rotating proximal side. In an ultrasonic endoscope having a rotational motion transmission means for transmitting the rotation or rotational vibration of the drive means and a signal transmission means for transmitting and receiving ultrasound signals, the rotational motion transmission means is a flexible and conductive hollow member. What is claimed is: 1. An ultrasonic endoscope, characterized in that a signal transmission means is formed by inserting a covered electric wire into the inside of the hollow member.

(2) The ultrasonic endoscope according to claim 1, wherein the hollow member is used as a shield wire that covers the outer periphery of a coated electric wire as a core wire.

(3) The ultrasonic endoscope according to claim 1, wherein the rotational motion transmission means is made of copper alloy or stainless steel.

(4) The ultrasonic endoscope according to claim 1, wherein the rotating means has a surface plated with silver, gold, or the like. −
