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.
In an ultrasonic applicator for the ultrasonic examination of an object, having an extended carrying body, which has an application surface to be directed to the object and, in the vicinity of this application surface, a number of ultrasonic transducer elements, which are arranged parallel to one another along the longitudinal axis of the carrying body, and with a guide channel in the carrying body which extends toward the application surface and is intended to receive a biopsy needle, the improvement comprising said carrying body being made up of two extended partial bodies each of which has a guide groove on one side, the two extended bodies being connected at a means for permitting the two extended partial bodies to move from a closed to an open position, said ultrasonic transducer elements being divided into two groups, each partial body having a surface along which one of said two groups of ultrasonic transducer elements is arranged, both partial bodies being positioned with respect to one another in such a manner that in the closed position said guide grooves form said guide channel that serves to guide said biopsy needle, and said two partial body surfaces form said application surface.
An ultrasonic applicator for biopsy with a guide channel for receiving a biopsy device, said ultrasonic applicator comprising two partial applicators, each comprising ultrasonic transducer means, the two partial applicators being that rotatably connected with one another and operated parallel with one another, and which in a closed position form said guide channel with one another.
