Abstract: An ultrasound probe includes a plurality of piezoelectric elements arranged in an array, a plurality of drawn-out signal lines drawn out from the plurality of piezoelectric elements, and a print board on which a plurality of connection conductors are formed for connecting between a plurality of communication cables connected to an ultrasound diagnostic apparatus body and the plurality of drawn-out signal lines, respectively, connection-conductor insulation layers being formed on the printed board so as to cover respective outer peripheries of the plurality of connection conductors, and a connection-conductor ground conductive layer being formed on the printed board so as to cover individual outer peripheries of the connection-conductor insulation layers, whereby the plurality of connection conductors are shielded from one another.

Abstract: The present invention relates to a biopsy needle, a sample extracting unit, a biopsy apparatus, and a biopsy needle control method. The biopsy needle includes an outer tube and an inner tube movably disposed within the outer tube. The inner tube has a plurality of inner openings defined in a side wall thereof. The outer tube has at least one outer opening defined in a side wall thereof. In response to movement of the inner tube, the outer opening selectively overlaps one of the inner openings thereby to define a communication port which communicates with an interior of the inner tube. The biopsy needle is incorporated in the sample extracting unit and the biopsy apparatus, and is controlled by the biopsy control method.
