ABSTRACT:
A first ultrasound transducer (24) is mounted in the interior of an examination head (4), which is rotatable around an axis (26) by means of first and second gears (52, 56) and by means of a drive shaft (22) which is driven by an electric motor (106) for scanning a first examination surface. The axis (26) is aligned perpendicular to the distal end of the drive shaft (22). The two gears (52, 56) are preferably fashioned as bevel gears. The second gear (56) is secured to the end of the drive shaft (22) and has a depression (60) into which the first ultrasound transducer (24) passes when it turns. A compact structure is achieved in this way. A second ultrasound transducer (90) is secured to the second bevel gear (56), which turns around the drive shaft (22) and thereby scans a second examination surface having the shape of an envelope of a cone which is positioned not entirely perpendicular relative to the first examination plane. Both transducers (24, 90) are rotatorily driven by the same drive shaft (22), which results in a simple design. The device is particularly suitable for vaginal and rectal examinations.
