Abstract: A skin punch device comprises a gripping handle with a center passage, through which a reciprocating plunger extends. A disposable cutting tip is releasably connected to the handle. The cutting tip has a tip cavity with a base from which extends a biopsy chamber that terminates at cutting edges. The base has an aperture through which a slidable push-rod extends. The push-rod has a disc end located in the biopsy chamber. The plunger and push-rod are in axial alignment, so that when the plunger is moved, the push-rod will also move in tandem. Movement of the push-rod will simultaneously cause the disc end to pass through the biopsy chamber and eject a cut tissue sample lodged in the chamber. Further movement of the plunger will result in engagement with the tip cavity and dislodgement of the entire disposable cutting tip from the end of the gripping handle.
