Abstract
A puncturing device for extracting organic samples, and which includes a puncturing cannula ending in a needle tip, the lumen of the puncturing cannula being designed as a suction channel, and a flushing line for supplying a flushing agent. Behind the needle tip of the puncturing cannula a single-lumen puncturing area is provided, which is followed by a double-lumen area departing from a connecting site at which the flushing line is fluid-tightly attached to the puncturing cannula. At a distal end of the flushing line is provided at least one transfer opening into the suction channel of the puncturing cannula.

A puncturing device for taking organic samples, comprising:
- a puncturing cannula tapering to a needle tip, the puncturing cannula having a lumen configured as a suction channel;
- a flushing line configured to supply a flushing agent, wherein adjacent to the needle tip is provided a single-lumen puncturing area followed by a double-lumen area departing from a connecting site where the flushing line is attached in a fluidically sealed manner to the puncturing cannula;
- at least one transfer opening located at the distal end of the double-lumen area and opening into the suction channel provided at the distal end of the flushing line, wherein the puncturing cannula has a first diameter in the puncturing area that is less than a second diameter of the puncturing cannula in the double-lumen area.
A puncturing device for extracting eggs for in-vitro fertilization, the puncturing device comprising:
- a puncturing cannula including a needle tip and a lumen having a suction channel;
- a flushing line to supply a flushing agent, wherein a single-lumen puncturing area is provided adjacent to the needle tip, followed by a double-lumen area departing from a connecting site where the flushing line is attached in a fluidically sealed manner to the puncturing cannula;
- a transfer opening located at the distal end of the double-lumen area and opening into the suction channel provided at the distal end of the flushing line,
- wherein the puncturing cannula has a first diameter in the puncturing area that is less than a second diameter of the puncturing cannula in the double-lumen area.
