  • Adjustable endoscopic traction device
    Patent number: 12376841
    Abstract: The aim of the invention is to provide a traction device for sufficiently exposing the submucosa so as to provide suitable conditions for the dissection device to move freely throughout the entire dissection of the tumoral mucosa. The traction device (1) of the invention is characterised in that it comprises a proximal anchor (3) that is mounted so as to move relative to an elastic member (2) between a minimum proximal distance and a maximum proximal distance, and in that the traction device comprises an adjustment member (6) configured to adjust the maximum proximal distance between the initial maximum proximal distance and a final maximum proximal distance smaller than the initial maximum proximal distance.
