Abstract
An ultrasonic diagnostic probe includes: a swinging mechanism for swinging a piezoelectric vibrator provided in an accommodating part at an end of a tube-like shaft, around an axis parallel with an ultrasonic transmission and reception face; and a rotating mechanism for rotating the piezoelectric vibrator around an axis perpendicular to the ultrasonic transmission and reception face. The rotating mechanism includes: a pedestal provided with a semicylindrical part; a seat pedestal in which a concave part having a curvature that matches the semicylindrical part is formed so as to rotatably support the pedestal by the semicylindrical part being engaged with the concave part; and a swinging wire for urging the pedestal into a swinging motion.
Claims14
An ultrasonic diagnostic probe comprising:
- a tube-like shaft having an end and an accommodating part provided at the end;
- a piezoelectric vibrator disposed in said accommodating part, having an ultrasonic transmission and reception face;
- swinging means provided in said accommodating part, which swings said piezoelectric vibrator around an axis parallel with the ultrasonic transmission and reception face of said piezoelectric vibrator, the swinging means having a relative position which is substantially fixed with respect to the tube-like shaft;
- and
- rotating means provided in said accommodating part, which rotates said piezoelectric vibrator around an axis perpendicular to the ultrasonic transmission and reception face of said piezoelectric vibrator.
