Abstract: An ultrasonic applicator for biopsy which includes a carrying body formed from two extended partial bodies (4, 6). Each partial body has a guide groove (8, 10) introduced in one side. On the surface (12, 14) of each partial body (4, 6), a group (16, 20) of ultrasonic transducer elements is arranged. The two partial bodies can be positioned with respect to one another in such a manner that in a closed position the guide grooves (8, 10) form the guide channel (38) that serves to receive a biopsy needle (37). This lengthwise division of the applicator is advantageous because the row of transducer elements (16, 20) has no gap in the area of the guide channel (38) and when the applicator has both partial bodies in the open position it can be removed, leaving the biopsy needle in place. The partial bodies (4, 6) can be connected with one another in such a way that they can either swivel or be easily removed from one another.
