Zusammenfassung
(EN)

The device according to the invention for providing a percutaneous endoscopic gastrostomy (PEG) comprises a handle for handling the device. The wire that is to be inserted into the stomach of the patient is rolled on a wire spool that is mounted either in a rotatable manner on the handle part or on an attachment piece that can be attached to the handle. Aside from the puncturing cannula for puncturing the stomach, the device according to the invention comprises an insertion cannula for insertion the wire rolled on the wire spool into the stomach. The device according to the invention is characterized in that the puncturing cannula is designed as an outer cannula surrounding the insertion cannula, while the insertion cannula is designed as an inner cannula surrounded by the puncturing cannula, wherein the insertion cannula is guided into the puncturing cannula in a longitudinally displaceable manner. During the puncture of the stomach, the insertion cannula is recessed into the puncturing cannula. The design of the insertion cannula as an inner cannula and the puncturing cannula as an outer cannula provides the advantage that the puncture can be carried out only with the puncturing cannula. The design problem of an even transition between an insertion cannula as an outer cannula and a puncturing cannula as an inner cannula is solved by the device according to the invention. Moreover, puncturing and insertion cannulas made of steel can be produced with a comparable low technical effort and relatively low costs in great numbers without the need for both cannulas to be formed to each other for achieving a smooth transition.
