Biopsy system

A biopsy system comprising:

• a biopsy element for taking a sample of tissue to be examined from an organic body;
• and
• a fluorescence endoscopy element comprising a distal section with a decoupling of stimulation light and coupling of fluorescence light,
• wherein the distal section of the fluorescence endoscopy element is positioned in the biopsy element and is axially positionable in a distal position and in a proximal position,
• wherein for receiving the sample of the tissue to be examined, the biopsy element comprises a receiving space which in the distal position of the distal section of the fluorescence endoscopy element is distally closed and in the proximal position of the distal section of the fluorescence endoscopy element is distally open,
• wherein the distal section of the fluorescence endoscopy element comprises a radial seal which is configured to guide the distal section of the fluorescence endoscopy element in the biopsy element, such that in the receiving space, during a pulling back of the distal section of the fluorescence endoscopy element proximally in the biopsy element, a sucking-in effect is produced in the receiving space.
