Using Hall components to intelligently detect the electric start rotary motor and its braking mechanism

Abstract

The invention discloses a Hall element wisdom detection electrically-started rotary motor and a braking mechanism thereof. The rotary motor refers to a medical electric drill used for medical surgery. The medical electric drill comprises a drill bit, a driving module, a microcontroller, a Hall element and a battery module, wherein the driving module is coupled to the drill bit; the microcontroller is coupled to the driving module; the Hall element is coupled to the microcontroller; the battery module is coupled to the Hall element. The instantaneous magnitude of current of the medical electric drill is obtained through the Hall element, and the magnitude of current and change of voltage are analyzed; when the Hall element transmits analyzed values of the magnitude of current and voltage to the microcontroller, the voltage will increase sharply at the moment when the medical electric drill penetrates through a bone during surgery; at this time, the microcontroller will sense the suddenly enhanced voltage and immediately generate a current to make the driving module control the drill bit to rotate reversely, so that the medical electric drill can be controlled to stop automatically to assist a doctor in judging the optimal time for stop in the process of performing a drilling operation, and then the effect of automatic buffer to stop feeding and rotating is achieved.

Description

technical field [0001] The present invention relates to an electrically activated rotary motor and its braking mechanism which are intelligently detected by Hall components, especially an auxiliary physician assisting and actively judging the best time to stop the operation when performing drilling operations, so as to shorten the operation time. Time, stabilize the surgical process, reduce human error, and reduce surgical risk, and the medical power drill with automatic buffer stop feed and stop rotation effect. Background technique [0002] With the development of the economy and the improvement of living material conditions, the average life expectancy of people in Taiwan, China has increased significantly, and the Chinese people have paid more and more attention to the quality of medical care. In addition to the research and development of related medical technologies, the design and development of medical equipment is also a very important topic. Especially in surgical...

Problems solved by technology

[0006] According to the above structure, the medical electric drill includes a drill bit, a microprocessor, a pressure sensing unit, a torque sensing unit and a gravity sensing side unit, which can sense changes in pressure and Newly during surgery, and provide real-time information to the microcomputer. Processed by the processor to determine the working period of the drill bit on the bone, and then the microprocessor calculates the displacement of the drill bit based on the acceleration voltage signal. Although it can provide the doctor with the real-time information of the drilling depth of the drill bit of the medical electric drill at the first time, However, the doctor has to be distracted to control whether the drill bit of the medical electric drill continues to perform the drilling action. If there is a slight carelessness, there may still be risks at any time during the operation, and it needs to be improved urgently.
