An ultrasonic probe including a rotary transmission shaft to be rotated by a driver connected thereto, in which an oscillator is arranged in opposition to one end of the transmission shaft for emitting a ultrasonic wave, and a scanner such as a mirror is mounted to the one end of the rotary transmission shaft for reflecting the ultrasonic wave emitted by the oscillator to carry out an ultrasonic wave scanning. The rotary transmission shaft includes a first shaft having a first diameter, connected to the scanner, and a second shaft having a second diameter, connected to the driver with the first diameter being smaller than the second diameter. The oscillator as the scanner may be directly mounted to the end of the transmission shaft. |

DETAILED DESCRIPTION Accordingly, it is an object of the present invention to provide an ultrasonic probe in view of the aforementioned defects and disadvantages of the prior art, which is capable of inserting into a fine portion such as a fine blood vessel or the like and preventing an irregular rotation of a mirror to obtain a good ultrasonic wave image.
In accordance with one aspect of the present invention, there is provided an ultrasonic probe, comprising a rotary transmission shaft to be rotated by a driver connected thereto, an oscillator arranged in opposition to one end of the transmission shaft for emitting a ultrasonic wave, and scanning means mounted to the one end of the rotary transmission shaft for reflecting the ultrasonic wave emitted by the oscillator to carry out an ultrasonic wave scanning, the rotary transmission shaft including a first shaft having a first diameter, connected to the scanning means, and a second shaft having a second diameter, connected to the driver, the first diameter being smaller than the second diameter.
In accordance with another aspect of the present invention, there is provided an ultrasonic probe, comprising a rotary transmission shaft to be rotated by a driver connected thereto, and scanning means mounted to the one end of the rotary transmission shaft for emitting a ultrasonic wave to carry out an ultrasonic wave scanning, the rotary transmission shaft including a first shaft having a first diameter, connected to the scanning means, and a second shaft having a second diameter, connected to the driver, the first diameter being smaller than the second diameter.
