A puncturing device for extracting egg cells for in-vitro fertilization (IVF) includes a puncturing cannula that can be connected by means of a multiway valve to a suction line or a flushing line. The multiway valve is provided with a foot-operated, mechanical or electro-motive drive mechanism for switching the multiway valve from a suction position to a flushing position and vice versa. |
