Surgical milling cutter bracket

A surgical milling cutter bracket, comprising

• a retaining base (1) having a through hole (12), into which a milling cutter (11) is inserted,
• an upper part of the retaining base (1) being attached with a finger guide (4) having an L-shaped support frame on a top of the finger guide (4) rotatable by the finger guide (4),
• a downward protrusion (9) extending downwards perpendicular to a short side (8) being fixing to a distal end of the short side (8) of the L-shaped support frame, wherein the short side (8) runs perpendicular to a vertical central axis (13) of the through hole (12), around which the finger guide (4) rotates,
• a lowest point of the protrusion (9) being lower than a lowest point of a cylindrical head (10) of the milling cutter (11) during operation of the milling cutter (11);
• a bolt (3) having a through hole (12) being fixed within a cavity inside of the finger guide (4), rotatable by the finger guide (4),
• a depressor (7) extending and fixed to the upper part of the retaining base (1) over a nut (6) beneath to attach the finger guide (4) to the retaining base (1), and
• the bolt (3) passing through a hole of the depressor (7) and being connected to the nut (6), such that the milling cuter (11) can be driven to rotate by the finger guide (4).
