Tonsil snare, which consists of (a) a long, solid square chrome-plated metal shaft with threading at the edges and an oval thumb grip at the operator's end; the other end of the shaft is bent upward at a 45° rounded angle, and has (b) a cannula made of hollow lcylindrical metal tubing attached at its top; a round thumb screw below the point where the cannula attaches holds it in place or allows it to be removed; a long, solid cylindrical piece of metal with a flattened tip that has two holes, goes through the cannula; this piece is attached at its other end to two circular finger grips that also attach to the square shaft by means of a sliding collar; the solid cylindrical piece at the top will retract into the cannula when the finger grips are pulled back; there is a round wing nut at the end of the square shaft that can be turned with the aid of four cylindrical knobs on its outer edges; this wing nut controls how far down the shaft the sliding collar will move.
