<p>The invention concerns a bistoury surgical blade designed for fine surgery. Said blade is characterised in that it is twice arched in its plane or in its field (that is in three dimensions), in the form of a contra-angle handpiece, so that its end (D) intersects the geometrical axis (C) of the bistoury angle, said end being finely rounded or pointed, and double-bevelled ground on its two edges (D1 and D2). Said blade is designed in particular for use in periodontal and oral surgery, to perform accurate and sinuous incisions in regions of very difficult access.</p> |
