Intelligent bone drill and control method thereof

The invention discloses an intelligent bone drill. A common bone drill motor is provided with a strain torque sensor, a revolution speed transducer or a pressure sensor; the bone drill motor is further provided with an embedded intelligent control module that receives an induced signal collected by the sensor and judges the same to control the bone drill motor. The invention further discloses a control method of the intelligent bone drill. Beneficial effects of the invention lie in that a base body of the common bone drill motor is provided with a revolution speed transducer composed of a hall sensor and a metal reading code disk, a torque sensor and a pressure sensor to measure and display revolution speed, torque and pressure of the drill realtime, which realizes judgment of whether the drill pierces the bone tissue and control of automatic stop and reversion; the bone drill motor is provided with an ultrasonic transducer that can measures drill depth of the drill accurately. The improvement can provide effective data during operation for operator and reliable protection realtime.
