Sterile surgical drills generally include: the electric drill comprises an electric drill shell, a direct current speed reduction motor arranged in the electric drill shell and a drill chuck arranged at the front end of a motor shaft; the electric drill shell is provided with a handle, a battery bin is arranged in the handle, and a battery bin cover is arranged at the lower end of the handle to seal the battery in the battery bin; the front wall of the handle is provided with a switch, the battery is connected with the switch and the motor through wires to supply power to the motor, and the start, stop and rotating speed of the motor are controlled through the switch. The electric swing saw for osteotomy has the same structure as an electric drill except that a saw blade swing mechanism is arranged at the front end of a motor shaft.
The electric drill or the swing saw is sterilized by adopting a high-temperature and high-pressure method in a hospital before operation, but the battery is non-sterile because the battery can not bear the high-temperature and high-pressure sterilization and is required to be taken out; in order to isolate bacteria, a battery is sealed in a battery box. However, when the battery is loaded into the sterilized drill, there is still a possibility that the battery will hit the drill housing, thereby contaminating the housing. In order to solve the problem, a mode of a sterile isolation guide sleeve is adopted at present, and a battery is led into a battery compartment of the electric drill through the sterile isolation guide sleeve. However, the product cost is increased, the butt joint of the isolation guide sleeve and the battery compartment inlet is easy to fall off and fall down by means of manual hand-holding, and the unstable factors and the complexity of the operation are increased, so that the operation time is prolonged.
