摘要： A surgical milling cutter includes a milling cutter bracket, a locking device and a bottom electric motor connected successively. The milling cutter bracket includes a fixing seat with a through hole. A finger guide apparatus with an L-type first bracket at the top end thereof is provided on the upper part of the fixing seat. The end of the L-type first bracket's short side is provided with a downward projection. The lowest point of the projection is lower than that of the milling cutter's cylindrical head when the milling cutter is working normally. The surgical milling cutter utilizes the projection to prevent the possibility of an object contacting with the cylindrical head, thus avoiding an object being cut unevenly. Meanwhile, the L-type bracket can be driven by the finger guide apparatus to rotate so as to change the running direction of the milling cutter, thus facilitating surgical procedures.

摘要： A craniotomy drill includes a main machine, a retarder and a locking seat. A drill transmission rod connected to the output shaft of the retarder is inserted in the locking seat. The main machine comprises a handle at the lower portion and an accommodating part at the upper portion, with a stator and a rotor of a DC electric motor being provided inside the accommodating part and a wall of the accommodating part being the stator housing of the DC electric motor. This craniotomy drill has a simple structure with the wall of the accommodating part as the stator housing of the electric motor, such that the volume and the weight are reduced. It is safe in use without the risk of the electric motor sliding out. By utilizing materials and processes of water resistant technology and an integrative design, a relatively good water resistant performance is achieved.

摘要： A surgical milling cutter bracket includes a retaining base having a through hole. The upper part of the retaining base is provided with a finger guide having an L-shaped support frame on the top of the finger guide. A downward protrusion is provided at the end of the short side of the L-shaped support frame. The lowest point of the protrusion is lower than the lowest point of the cylindrical head of the milling cutter during normal operation of the milling cutter. A bolt having a through hole at the center is fixed within the cavity of the finger guide. A depressor is provided on the upper part of the retaining base. The bolt passes through a hole of the depressor and is connected to a nut. The protrusion is able to prevent an object from contacting the cylindrical head, thus avoiding cutting the object unevenly.
