SURGICAL MILLING CUTTER BRACKET

摘要

A surgical milling cutter bracket includes a retaining base (1) with a through hole. A finger guide (4) with an L-shaped supporting 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 supporting 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. A bolt (3) with a center through hole is fixed in the cavity of the finger guide (4). A pressing plate (7) is disposed at the upper part of the retaining base (1), and the bolt (3) passes through the hole of the pressing plate (7) to connect with a nut (6). The protrusion (9) is able to prevent an object from contacting the cylindrical bit (10), thus to avoid cutting the object unevenly. Additionally, the finger guide (4) may drive the L-shaped supporting bracket to rotate to change the motion direction of the milling cutter, which facilitates the operation.
