发明名称 Forceps for the extraction of teeth
摘要 Forceps for the extraction of teeth having two double-armed levers which are connected to one another via a pivot bearing and in which one pair of adjacent arms is designed as handles and the other pair is designed as jaws for gripping and holding the tooth. The jaws can be pivoted over a limited angle relative to one another about an axis which extends essentially at right angles to the jaws and at right angles to the pivot bearing. In this way, the jaws can move laterally toward one another and thus adapt themselves laterally to the anatomical shape of the tooth, e.g. engage in a simple manner in bifurcations of a tooth without it being possible for any lateral forces to act upon the tooth which impair adhesion of the jaws on the tooth or the tooth itself and may break the dental roots (radices) (drawing: Fig. 2). <IMAGE>
