Ultrasonic probe
First Claim
1. A ultrasonic catheter probe adapted to be placed in a body vessel, comprising:
- a rotary transmission shaft comprising a first shaft portion and a second shaft portion at the distal tip of said probe, said first shaft portion having a bendable extent and greater flexibility than said second shaft portion, such that the first shaft portion can bend more easily than said second portion, said rotary transmission shaft being rotatable by a driver connected thereto;
an oscillator arranged in opposition to one end of the transmission shaft for emitting an 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, said first shaft portion having a first diameter, connected to the scanning means, said second shaft portion having a second diameter, connected to the driver, the first diameter being smaller than the second diameter.

Abstract
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.
