Abstract
The utility model specifically relates to an electric bone drill, including a bone drill casing. A motor is installed inside the casing and is provided with a transfer switch. A U-shaped fixing frame is installed above the motor and is provided with two concentric circular holes. A blocking rod of a hollow drill bit is installed through a bearing of the two concentric circular holes. A power output shaft of the motor is connected with the blocking rod of the hollow drill bit by a decelerating transmission device. The front end of the blocking rod of the hollow drill bit is provided with a bone drill bit through a drill block. The utility model conquers the disadvantage that the bone drill bit can be easily bended to make the bone drill bit rotate stably. The utility model is safe and stable for using to avoid the operation damnification and is applicable to the hospital.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of electric bone drill.
Background technology
At present, employed electric bone drill in hospital operating room mainly comprises the bone drill housing, be provided with motor in housing, be connected with permutator on the motor, the outfan of motor is connected with the drill bit kelly by reducing gear, the drill bit kelly is installed with drill bit by drill chuck, used drill bit is and one-time fixes, and drill bit can not be adjusted, when using than long drill bit, drill bit is easy to break, easily curved, and rotate very unstablely, bone is easy to generate surgical injury, have unsafe factor.
Summary of the invention
