摘要： An ultrasonic transducer array, and a method for manufacturing it, having a plurality of transducer elements aligned along an array axis in an imaging plane. Each transducer element includes a piezoelectric layer and one or more acoustic matching layers. The piezoelectric layer has a concave front surface overlayed by a front electrode and a rear surface overlayed by a rear electrode. The shape of each transducer element is selected such that it is mechanically focused into the imaging plane. A backing support holds the plurality of transducer elements in a predetermined relationship along the array axis such that each element is mechanically focused in the imaging plane.

摘要： A bendable ultrasonic probe useful in endosurgical operations is provided having a therapy channel with a shape that is substantially unaffected by bending of the probe. The probe can be used to convey substantially nonbendable tools to the vicinity of an ultrasonic device that has been repositioned by bending the probe. A sheath is provided having a rigid, self-supporting body portion that may be used with the bendable ultrasonic probe. The sheath may have a therapy channel for conveying surgical tools. Also, the sheath may have a flexible balloon on one end for accommodating the bendable portion of the probe, which is disposed in the flexible balloon.

摘要： An articulated ultrasonic probe for endoscopic examination comprises a transducer head, for example, having one or more rows of independently actuable transducer elements extending along the surface of the probe, parallel to the axis thereof. The probe comprises an articulable section while the transducer head is journaled for rotation with respect to the tip of the probe. In use the tip of the probe is juxtaposed to a structure to be examined; the articulated section of the probe and the rotation of the transducer are controlled separately, such that the transducer elements can be juxtaposed to the structure to be examined. A series of angularly-spaced images may be formed by rotation of the transducer about its axis after articulation of the probe.

摘要： An improved composite ultrasonic transducer, and elements therefor, which may be made autoclavable, and a method of making these elements. A number of planar precursors comprising strips of piezoelectric ceramic material separated from one another by a polymer material are stacked one above another with the ceramic strips aligned with one another, and with electrical conductors disposed between each of the planar precursors. These precursors are then bonded to one another, to form a bonded assembly. The bonded assembly is then slit along parallel lines perpendicular to the direction of elongation of the ceramic strips, subdividing the strips into individual ceramic members and also subdividing the planar conductors, forming ribbon-like conductors extending between opposite sides of the array. The saw kerfs are filled with a hardening polymer material. The ribbon-like conductors reaching the edges of the assembly are then connected electrically in parallel, reducing the capacitance of the individual emitters. Criteria for selection of the materials of the ceramic members, the conductors, and other components of the transducer, and their relative proportions are given which allow the transducer to be steam-autoclavable.
