ENDOSCOPIC CUTTING DEVICE HAVING A CUTTING WIRE DIRECTED THROUGH OPENINGS IN A TUBE TO FORM TWO DIATHERMY BLADES, AND A PROBE FOR A PERCUTANEOUS ENDOSCOPIC GASTROSTOMY

摘要

An endoscopic cutting device for cutting free a probe, provided with a retaining plate, which, within the scope of a percutaneous endoscopic gastrostomy, is arranged in a stomach wall and is overgrown by the gastric mucosa, wherein, for the adjustment of the cutting element provided at a distal end of a tube via a pulling cord, an actuation force of an actuation element can be transmitted to same. In addition, the cutting device includes a cutting wire which is electrically heatable and connected to the pulling cord, and which runs outside the tube via a distal section to form a first diathermy blade. In addition, the distal end of the tube is slanted at an angle to the transverse plane thereof to form a tip, wherein the tip is facing the first diathermy blade. Furthermore, the cutting wire is directed externally around the tip to form a second diathermy blade.
