[0062] In one embodiment, the battery assembly 31 further includes a PWM regulation chip, which is electrically connected to the button 33 and the DC-DC boost circuit for adjusting the brightness of the light.

[0063] By setting the PWM regulation chip to adjust the duty cycle of the MOS tube, the brightness of the light board 32 can be effectively adjusted, allowing doctors to more flexibly choose the light intensity, so as to adapt to different surgical scenarios.

[0064] In a specific embodiment, the built-in light source device has three levels of brightness. The hook-opening piece 2 is rotated to an appropriate position and locked, and then the button 33 is pressed. Each time the button 33 is pressed, a level of brightness is turned on. When the button 33 is pressed for the fourth time, the light is turned off.

[0065] In a specific embodiment, the handle 1 is designed with a curved arc, which is ergonomically designed and can reduce fatigue of medical staff.

[0066] Specifically, the shell of the utility model is mainly made of plastic, and the overall weight is light, so doctors and nurses are not easily fatigued when using it. In addition, the utility model has fewer external devices, is easy to carry, and can be used as a disposable consumable due to its low cost, and can be treated as medical waste after use, reducing the steps of repeated disinfection in hospitals.
