Beschreibung
Zusammenfassung:	A cartridge syringe comprising an outer casing (2) for receiving a cartridge (3), and a displaceably guided plunger (4) disposed at the rear end of the outer casing (2), wherein the plunger (4) comprises an outer sleeve (43) having a guiding channel (49), and a core (41) disposed in the guiding channel (49) of the outer sleeve (43), so that the core (41) can be moved along its longitudinal axis in the guiding channel (49) of the outer sleeve (43) and relative to the outer sleeve (43), wherein the cartridge syringe comprises at least one spiral guiding groove (25) arranged at the inner surface of the outer casing (2), or arranged at the outer surface of the outer sleeve (43), so that upon rotating the outer sleeve (43) of the plunger (4) in the outer casing (2), the outer sleeve (43) is forcing the distal end of the plunger (48) to engage with the proximal end (33) of the cartridge (3) in a radial rotational movement.
