The Praxis Medical CytoCore is a syringe-holding device for performing a biopsy of soft tissue for diagnostic sampling. It is equipped with a scissor-slide mechanism for drawing back the syringe plunger to create suction, and an internal motor which rotates the needle clockwise and counterclockwise motion to facilitate cellular material harvesting. The device places the hand relatively close to the needle tip while the hand is in a position of natural function, providing greater tactile sensation of the texture of the lesion and enabling accurate needle placement using fine motor control of the hand. The device enables an operator to place a needle into a target area to harvest cells.
A hand-operated device designed to hold a biopsy syringe to facilitate precision aspiration of a tissue specimen through a biopsy needle. The holder is typically made of metal and plastic materials and typically designed as a lightweight, hand-held frame in which the syringe is placed and its piston withdrawn using a sliding handle in the frame; a stopper may be included to prevent further aspiration at a predetermined point. This is a reusable device.
