Claim:
1. An automated stereotactic apparatus for tissue sampling under ultrasonographic guidance, comprising: an invasive tubular device assembly, guided by a positioning assembly and propelled by a powered propulsion assembly; the invasive tubular device assembly, provided as a non-reusable hand-held operating device comprising an invasive tubular device frame having a longitudinal rail guide on each sidewall of said invasive tubular device frame and an invasive tubular device, wherein said invasive tubular device frame is configured to slidably house the invasive tubular device inside said invasive tubular device frame, and wherein said invasive tubular device is reversibly coupleable with the powered propulsion assembly so as to axially move along said longitudinal rail guide of said invasive tubular device frame; the positioning assembly, provided as a hand-held operating device comprising a position alignment assembly and a positioning control assembly, wherein said position alignment assembly is configured to movably block a portion of ultrasonographic waves to produce an ultrasonographically visible linear shadow line in an ultrasonographic display, wherein said positioning control assembly is reversibly coupleable with the invasive tubular device assembly, and wherein said positioning control assembly is configured to synchronize axial rotation of said positioning control assembly with movable blockade of the portion of the ultrasonographic waves in the ultrasonographic display; and the powered propulsion assembly, provided as a hand-held operating device comprising a transmission assembly having a pivotable gearbox and an electric motor device, wherein said powered propulsion assembly is reversibly coupleable with the invasive tubular assembly, wherein said pivotable gearbox is configured to pivot said powered propulsion assembly thereof at a proximal end of said powered propulsion assembly, and wherein a rotational power generated by the electric motor device is configured to be transmitted to the invasive tubular device assembly over a pivoting range of said proximal end of said powered propulsion assembly.
