A "swallowing" bone punch modelled on the dentition of the snake Anaconda was developed, which sterilely holds the resectate inside the instrument after the forceps have been closed. The next bone piece can be resected immediately. The resectates are in the cartridge in the order in which they were removed and can be used for biopsies or removed and implanted again at the end of the operation. The punch or cartridge can hold 40 resectates, which means that the punch can remain in the operated area for a long time without being emptied constantly. The cutting mechanism has been modified from the carnivorous dentition of the feline (Feliformia). This saves approx. 50% of the force required for cutting and the cuts have clean cutting edges in contrast to the traditional punch cutting mechanism. It could be shown that biomimetics enables an effective transfer into medical technology.
