<p>The extraction forceps has an extraction arm (5) that provides a specific pulling force in a longitudinal axis of horse tooth, where the drawing force provides a changeable base pressure in the longitudinal axis of the horse tooth. The forceps works according to a principle of a parallel screw clamp and is insertable in an upper jaw and a lower jaw, where the forceps jaws (2) are replaceable. The extraction arm has a hooking device (6) at a lower side for hooking in screws (3, 4) at the forceps.</p> |
