[0003] Knowing how endoscopes work, it turns out that when a doctor manipulates a catheter inside a patient to deflect a deflectable tip with a camera lens, it can cause the lens to lose the view horizon, which is the lens loses its orientation reference line, which in turn causes the display to display a The pattern of the image is tilted; in addition, the temperature of the human body is higher than that of the outside, so when the endoscope is inserted, due to the temperature difference between the endoscope and the human body, the gas on the surface of the lens will condense and condense into water droplets, thereby forming A large area of water mist affects its shooting work, so endoscopic equipment with a field of view that deviates from the center direction came into being

The invention relates to the technical field of visual field deviation adjustment of endoscopes and discloses an endoscope device with a visual field deviated from a center direction. The endoscope device comprises a pipe, wherein a spring lever is movably connected inside the pipe, the surface of the spring lever is movably connected with a supporting rod, the surface of an adjusting member is movably connected with a lens, one side, far away from the supporting rod, of the adjusting member is movably connected with a demisting plate, the surface of the demisting plate is fixedly connected with a magnetic attraction plate, a wiping member is movably connected inside the demisting plate, one end, far away from the supporting rod, of the spring lever is movably connected with a squeezing plate, and the surface of the squeezing plate is movably connected with a photosensitive box. Therefore, a light plate is triggered to work to emit light with certain wavelength, the lens will slightlymove while the photosensitive box is pulled to move by a doctor, therefore, the light will be received by a reflecting panel and reflected to the surface of an air spring, the air spring expands to the surface of the lens, and thus, the effect of slightly adjusting the lens according to an optical principle of reflection to keep the lens level is achieved.
Description
technical field [0001] The invention relates to the technical field of endoscope field of view deviation adjustment, in particular to endoscopic equipment whose field of view deviates from the central direction. Background technique [0002] An endoscope is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. It can enter the stomach through the mouth or enter the body through other natural channels, and the endoscope can be used to see Lesions that cannot be shown by X-rays are one of the essential equipment in the medical field. [0003] Knowing how endoscopes work, it turns out that when a doctor manipulates a catheter inside a patient to deflect a deflectable tip with a camera lens, it can cause the lens to lose the view horizon, which is the lens loses its orientation reference line, which in turn causes the display to display a The pattern of the image is tilted; in addition, the tem...
