摘要：
A surgical milling cutter includes a milling cutter bracket, a locking apparatus, and a bottom electric motor connected sequentially. The milling cutter bracket includes a retaining base (1) with a through hole. A finger guide (4) with an L-shaped first bracket on the top of the finger guide is disposed at the upper part of the retaining base (1), and a downward protrusion (9) is disposed at the end of the short side (8) of the L-shaped first bracket. The lowest point of the protrusion (9) is lower than the lowest point of a cylindrical bit (10) of the milling cutter during normal operation of the milling cutter. The surgical milling cutter adopts the protrusion to prevent an object from contacting the cylindrical bit, thus to avoid uneven cutting of the object. Additionally, the finger guide may drive the L-shaped bracket to turn to change the motion direction of the milling cutter, which facilitates the operation in surgery.
