Problems solved by technology
However, the current surgical magnifying glass cannot automatically adjust the focal length. Once the surgeon's head moves slightly, the image will be blurred, causing the doctor to feel dizzy.
As a result, doctors are forced to fix their positions for a long time, causing fatigue in the cervical and lumbar spine, which directly affects the operation speed, effect and health of doctors.

The invention provides automatic focusing operation amplifying spectacles. The spectacles comprise an optical lens group, a CCD (Charge Coupled Device) image sensor, a microprocessor, a focalizer, spectacles and a frame, wherein the CCD image sensor is positioned behind the optical lens group and is responsible for collecting images and transmitting a signal to the microprocessor through the frame; after processing the signal, the microprocessor outputs a control signal to the focalizer; and the focalizer quickly achieves the effect of automatic focusing by adjusting the distance between a front lens and a rear lens.
Description
Technical field: [0001] The patent of the present invention relates to the technical field of medical instruments and devices, in particular to an automatic focusing surgical magnifying glass. Background technique: [0002] During surgical operations, it is very important to correctly identify the surgical site, especially when performing operations on small parts, it is very difficult to observe with the naked eye, and optical instruments, such as magnifying glasses, are often used. However, because the current surgical magnifying glass cannot automatically adjust the focal length, once the surgeon's head moves slightly, the image will be blurred, causing the doctor to feel dizzy. Thereby forcing the doctor to fix the body position for a long time, causing fatigue of the cervical spine and lumbar spine, the consequence is to directly affect the operation speed, effect and the health of the doctor. Invention content: [0003] In order to overcome the above shortcomings, t...
