Description

Technical Field

[0001] The present invention mainly relates to the technical field of surgical video recording, and in particular to a head-mounted automatically adjustable headlight video recording system and method. Background Art

[0002] The commonly used headlights in the prior art use optical lenses to gather the divergent light sources together to form a circular light spot with uniform brightness. They are widely used in outpatient examinations and surgical supplementary lighting, especially for open surgeries with small incisions and deep cavities. Medical examination lights can provide stable light, allowing doctors to observe symptoms more clearly and make correct judgments.

[0003] Head-mounted surgical cameras are essential tools for medical treatment, teaching, scientific research and telemedicine. Through surgical video technology, the risks of surgical contamination and infection caused by direct viewing next to the operating table are avoided. At present, the commonly used head-mounted headlights combined with video recording systems can provide stable lighting for the surgical environment while saving and recording the doctor's first-person surgical operation video, which is convenient for real-time sharing of surgical operations for teaching, etc.; however, the brightness adjustment of existing head-mounted medical examination lights is mostly controlled by buttons. It is not convenient for doctors to adjust the brightness of the headlights during surgery, and assistants are required to help adjust, which is easy to affect surgical operations; the existing head-mounted surgical video recording system relies on buttons or mobile phone APPs to adjust parameters such as white balance, and there is also the problem of difficulty in adjustment during surgery; the existing head-mounted headlight video recording system needs to adjust and fix the headlight and camera angle before surgery, and cannot be freely adjusted during surgery; the existing headlight video recording system, the control of the headlight and the video recording system are all separately controlled, and the two modules cannot be linked; the existing headband requires the assistant to help adjust the tightness after the doctor wears it, which increases the preoperative preparation time and the tightness is difficult to adjust perfectly. Summary of the invention

[0004] The purpose of the present invention is to provide a head-mounted automatically adjustable headlamp recording system and method to improve the deficiencies of the prior art. The separate microcontroller unit module MCU can reduce the weight of the head; the automatically adjustable headband can reduce the preoperative preparation time and improve work efficiency; the adaptive headlamp brightness adjustment can reduce the operations caused by the brightness adjustment requirements during the operation and improve work efficiency; the camera white balance and focal length are automatically adjusted to avoid unclear recording caused by the change of working distance during the operation; the cloud platform real-time access function allows experts to remotely guide the operator, saving time and labor costs, so that more professional surgical operation guidance can serve more patients.

[0020] The brushless DC motor consists of a motor body and a driver, and is a typical mechatronics product. The stator winding of the motor is mostly made into a three-phase symmetrical star connection, which is very similar to a three-phase asynchronous motor. The rotor of the motor is attached with a magnetized permanent magnet. In order to detect the polarity of the motor rotor, a position sensor is installed in the motor. The driver is composed of power electronic devices and integrated circuits, etc. Its functions are: receiving the start, stop, and brake signals of the motor to control the start, stop, and brake of the motor; receiving the position sensor signal and the forward and reverse signals to control the on and off of each power tube of the inverter bridge to generate continuous torque; receiving speed instructions and speed feedback signals to control and adjust the speed; providing protection and display, etc. At present, many microprocessors have built the necessary functions of controlling motors into the chip, and the size is getting smaller and smaller; such as analog-to-digital converters (ADC), pulse width modulation (PWM)... etc. The brushless DC motor is an application that electronically controls the commutation of the AC motor to obtain similar characteristics to the DC motor without the lack of the DC motor mechanism. In the present invention, the brushless DC motor rotates to automatically adjust the headband to fit the operator's head, avoiding the operator manually rotating a button to adjust the headband to fit the operator's head, reducing operation time, improving efficiency, and also reducing the risk of bacterial infection to the patient during manual operation.

[0021] TF card, also known as MicroSD card, is a small, high-performance memory card widely used in mobile devices, cameras, drones and other fields. The working principle of TF card is based on flash memory technology. Its unique design and high efficiency make it an important part of the field of memory chips. Flash memory technology is based on the charge state in the storage unit, and represents 0 and 1 by adjusting the amount of charge. The TF card is composed of multiple storage units, which are connected together through circuits to form a storage array. When it is necessary to read the data in the TF card, the computer or other device sends the read instruction to the TF card through the interface. TF card can be used to store data in devices such as smart phones, tablet computers, digital cameras, etc., mainly used to expand the storage space in the mobile phone. In the present invention, the control host is connected to the head-mounted recording system through the camera interface and the headlight interface, and the memory card interface can be inserted with the TF memory card, which is convenient and flexible to plug and unplug and carry.
