Biopsy needle system having a pressure generating unit
Abstract:
A biopsy needle system includes a cylinder with a fluid connection end, an open end and a cylinder wall. A piston is coupled to a threaded spindle shaft. The threaded spindle shaft is configured to extend from the piston and through the open end of the cylinder. The piston is inserted in the open end such that a cylinder interior volume is defined between the piston and the fluid connection end. A spindle nut is mounted to the open end of the cylinder. The spindle nut is threadably engaged with the threaded spindle shaft and configured to displace the piston via a linear translation of the threaded spindle shaft when the spindle nut is rotated. A biopsy needle is connected in fluid communication with the fluid connection end of the cylinder.
