The inventive probe comprises a tubular body ( 1, 2 ) that accommodates a transducer ( 11 ), which emits a focussed incident ultrasonic wave toward structures to be examined and which receives the ultrasonic waves reflected by these structures. This transducer ( 11 ) is coupled to actuating means ( 4 ), comprises a piezoelectric assembly ( 15 ) capable of focussing the emitted beams and, adjacent to this assembly, comprises a spherical layer ( 20 ) made of a material that ensures a good transmission of the ultrasonic waves.
