[0012] Working principle or structural principle: When in use, first let the patient lie on the examination bed on one side of the examination table, then evenly apply lubricating oil on the outer surface of the outer tube 501, and then insert the outer tube 501 into the patient's anus until the annular plate 502 fits the skin; After the outer tube 501 has completed the expansion of the anus, the eyepiece 1 is put into the outer tube 501 from one end of the outer tube 501. When the eyepiece 1 contacts a plurality of groups of balls 503 at one end of the outer tube 501, the balls 503 are connected by ball joints to reduce the friction between the eyepiece 1 and the connecting wire 2 when they pass through the outer tube 501, thereby ensuring the smoothness of the surface of the eyepiece 1 and the connecting wire 2 and preventing scratches on the rectum. As the eyepiece 1 passes through the outer tube 501 and goes deep into the rectum to reach the designated position, the rubber airbag 407 is pressed, and the air pressure in the rubber airbag 407 is squeezed into the arc tube 405 through the air tube 406, and then enters the space between the fixed plate 404 and the piston plate 402 in the cavity 403 through the arc tube 405; by continuously pressing the rubber airbag 407, the air pressure between the piston plate 402 and the fixed plate 404 is increased, so that the air pressure pushes the piston plate 402 to move, and the piston plate 402 drives the lever 401 to rotate at one end of the eyepiece 1; The levers 401 at both ends are pressed simultaneously by the arc tube 405, so that the two groups of levers 401 can open the adhered rectum to a certain spatial range. The two groups of levers 401 can open the adhered parts by pressing the rubber airbag 407, which can expand the observation area and reduce the blind area, so that a stable space is formed between the rectal wall and the levers 401, avoiding blurring or distortion of the lens on the eyepiece 1 due to tissue compression, and improving the clarity of endoscope imaging; At the same time, the lever 401 drives the limit plate 408 to rotate in the accommodating chamber 410 while rotating, and the accommodating chamber 410 drives the torsion spring 409 to twist. After the inspection of the designated position in the rectum is completed, the rubber airbag 407 is released, and the lever 401 on the limit plate 408 is reset at one end of the eyepiece 1 through the reverse twisting action of the torsion spring 409. At the same time, the lever 401 drives the piston plate 402 to move in the cavity 403 to squeeze the gas between the piston plate 402 and the fixing plate 404 back into the rubber airbag 407. When the lever 401 is reset at one end of the eyepiece 1, the connecting wire 2 can be moved, so that the connecting wire 2 drives the eyepiece 1 to further penetrate or be taken out in the rectum. When checking a specified position subsequently, the rubber airbag 407 can be pressed repeatedly. Moreover, when the eyepiece 1 and the outer cylinder 501 are both taken out of the patient's anus for cleaning after the examination, the rubber airbag 407 can also be pressed to expand the two levers 401, so that one end of the eyepiece 1 can be comprehensively cleaned.
