Abstract

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.
