Control system for medical electric drill controller

Abstract

The invention discloses a control system for a medical electric drill controller. The control system for the medical electric drill controller comprises a micro processor, a switching power supply and a motor. The output end of the micro processor is connected with a switching power supply voltage regulating circuit. The output end of the switching power supply voltage regulating circuit is connected with the switching power supply. The output end of the micro processor is further connected with a photoelectric isolator. The output end of the photoelectric isolator is connected with a motor driving control and protection circuit. The motor driving control and protection circuit is connected with the motor. The micro processor controls the start-up, the shut-down and the positive and reverse rotations of the motor through the photoelectric isolator. Due to the fact that the micro processor controls the start-up, the shut-down and the positive and reverse rotations of the motor through the photoelectric isolator, the multi-layer protection is adopted on the motor.

Description

technical field [0001] The invention relates to the field of medical machinery, in particular to a control system of a medical electric drill controller. Background technique [0002] Medical electric drills are widely used in orthopedic medical operations. During the use of electric drills, motor damage is the main fault of medical electric drills. At present, motor damage is mainly caused by long-term blockage and high current, which burns the motor. The continuous switching of the motor is prone to high current and burns the motor, and the long-term overload causes the motor to overheat and burns the motor. Therefore, it is particularly important to solve this type of problem. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a control system of a medical electric drill controller. By designing a simple and perfect control system, the effect of protecting the motor and prolonging the service life of the motor ...
