Claims

[Scope of utility model registration request]

(1) An ultrasonic diagnostic transducer scanning device that rotates an ultrasonic transducer disposed in a distal opening of a cylindrical body in a fan shape using an electric motor as a drive source, which includes a drive mechanism including the electric motor; , a driven side mechanism including the ultrasonic vibrator, and the drive mechanism includes a drive shaft connected to the rotation shaft of the electric motor via a pair of bevel gears, and a drive shaft mounted at the rotation center of the drive shaft. The driven mechanism includes a flywheel and a crank pin provided eccentrically from the rotation center on the flywheel, and the driven mechanism includes a transducer holder that holds the ultrasonic transducer and a crank pin that holds the ultrasonic transducer. The crank arm has a support shaft that is rotatably supported and is oriented in the diametrical direction of the tip opening, and a holder pin that is provided on the vibrator holder eccentrically from its rotation axis, and the crank pin and the holder pin are connected to a crank arm. The transducer scanning device is operatively connected via the transducer scanning device.

(2) Utility Model Registration The vibrator scanning device according to claim (1), wherein the inertial mass of the driving mechanism is set to be sufficiently larger than the inertial mass of the driven mechanism.

(3) In the utility model registration claim (1), the main body has an opening formed in correspondence with the shaft end surface of the drive shaft, and the drive shaft is inserted with a driver inserted through the opening. The transducer scanning device is formed so as to be operated and turned up by a tool such as the above.

(4) Utility model registration In claim (1), the vibrator is configured such that the vibrator holder is connected to a potentiometer that electrically detects the reciprocating stroke of the vibrator through a pair of bevel gears. scanning device.
