The invention discloses a surgical milling cutter bracket which comprises a fixing seat (1) with a through hole, wherein, a finger guide apparatus (4) with an L-type support frame on a top end thereof is arranged at the upper part of the fixing seat (1), the tail end of a short edge (8) of the L-type support frame is equipped with a downward projection (9), and the lowest point of the projection (9) is lower than that of a cylindrical head (10) when a milling cutter works normally; a bolt (3) with a central through hole is fixed in a cavity of the finger guide apparatus (4); and a pressing disk (7) is arranged at the upper part of the fixing seat (1), and a nut (6) is connected with the bolt (3) through a hole on the pressing disk (7). In the invention, the projection can prevent an object from being contacted with the cylindrical head, thus avoiding occurrence of the phenomenon of unevenly cutting the object; and meanwhile the finger guide apparatus can drive the L-type support frameto rotate so as to change the running direction of the milling cutter, thus facilitating surgical procedures.
