The left side of the second partition 403 is provided with a flushing tube 405, and the right side of the second partition 403 is provided with a suction tube 406. The bottom of the connecting line 404 is connected to the endoscope head 3;

[0026] The device solves the problem of repeatedly withdrawing and cleaning the lens, which is very inconvenient and cannot be completed by a single operator, by setting the auxiliary component 4 and the adjustment component 5.

[0027] Furthermore, an adjustment assembly 5 is provided inside the mirror body 1, and the adjustment assembly 5 includes a positioning sleeve 501, a connecting rod 502, a first positioning block 503, a first slide groove 504, a pressure spring 505 and a fixing sleeve 506. The flushing tube 405 and the suction tube 406 are both fixedly connected with the positioning sleeve 501, the outer side of the positioning sleeve 501 is fixedly connected with the connecting rod 502, and the outer end of the connecting rod 502 is fixedly connected with the first positioning block 503. The two groups of first positioning blocks 503 are of different colors. In order to distinguish the flushing tube 405 and the suction tube 406, two groups of first slide grooves 504 are provided on the surface of the mirror body 1, and a pressure spring 505 is provided on the lower side of the positioning sleeve 501 and outside the flushing tube 405 and the suction tube 406. Two groups of fixing sleeves 506 are fixedly connected to the inner wall of the mirror body 1, and the flushing tube 405 and the suction tube 406 pass through the two groups of fixing sleeves 506 respectively. The two ends of the pressure spring 505 are respectively connected to the lower end of the positioning sleeve 501 and the upper end of the fixing sleeve 506. Figure 3 As shown, the structure is used to adjust the setting of the component 5. When flushing is required, the first positioning block 503 corresponding to the flushing tube 405 is pulled, and the flushing tube 405 is driven to move downward along the first slide groove 504 through the connecting rod 502, so that the end of the flushing tube 405 extends from the rigid tube 2, and physiological saline passes through the flushing tube 405 to flush the endoscope lens 3. When suction is required, the flushing tube 405 is reset, and the first positioning block 503 corresponding to the suction tube 406 is pulled, and the suction tube 406 is driven to move downward along the first slide groove 504 through the connecting rod 502, so that the end of the suction tube 406 extends from the rigid tube 2 to keep the surgical cavity clean.

[0028] Furthermore, the left and right ends of the first partition 401 are fixedly connected to the inner wall of the rigid tube 2, the rear end of the second partition 403 is fixedly connected to the first partition 401, and the front end of the second partition 403 is fixedly connected to the inner wall of the rigid tube 2. The interior of the rigid tube 2 is divided into three groups of storage chambers 402 by the first partition 401 and the storage chamber 402. A connecting line 404 is installed in the rear storage chamber 402, a flushing tube 405 is movably connected to the left front storage chamber 402, and a suction tube 406 is movably connected to the right front storage chamber 402. Figure 2 As shown, the structure is used to flush the endoscope lens 3 through the flushing tube 405, so that the endoscope lens 3 does not need to be repeatedly taken out of the nasal cavity for cleaning. Intermittent flushing not only cleans the lens but also flushes the surgical cavity, and is not easy to splash, thereby reducing the risk of occupational exposure. At the same time, the flushing tube 405 and the suction tube 406 are distributed toward the nasal cavity, do not occupy the space of the nasal cavity at all, and reasonably utilize the storage space design.

[0029] Furthermore, a guide assembly 6 is provided at the bottom of the rigid tube 2, and the guide assembly 6 includes a second positioning block 61, a guide tube 62 and a guide block 63. Two sets of second positioning blocks 61 are fixedly installed on the inner side of the bottom of the rigid tube 2 below the flushing tube 405 and the suction tube 406. The upper ends of the two sets of second positioning blocks 61 are respectively fixedly connected to the guide tube 62, and the lower end of the storage chamber 402 is fixedly connected to the guide block 63. Figure 5 As shown, the structure is used to guide the flushing tube 405 and the suction tube 406 through the second positioning block 61, the guide tube 62 and the guide block 63, so that they move along the second positioning block 61, the guide tube 62 and the guide block 63, thereby enhancing the stability of the device.

[0030] Furthermore, an inflatable bag 7 is fixedly installed at the bottom of the rigid tube 2, and an inflatable device and an indicator bag are connected to the inflatable bag 7 through an inflatable tube. Figure 5 As shown, the structure is used to wrap the end of the rigid tube 2 inside after the inflatable bag 7 is inflated, so as to avoid contact with the patient's skin during movement and cause damage, thereby providing a certain degree of protection for the patient.

[0031] Furthermore, a second slide groove 507 is provided on the surface of the mirror body 1. The second slide groove 507 is semicircular and is connected to the two groups of first slide grooves 504. The diameter of the connecting rod 502 is adapted to the first slide groove 504 and the second slide groove 507. Figure 3 As shown, the structure is used to drive the connecting rod 502 to move along the first slide groove 504 through the first positioning block 503. When it moves to the second slide groove 507, the first positioning block 503 is rotated along the second slide groove 507 to adjust the angle of the flushing tube 405 or the suction tube 406 to expand the contact area.

[0032] Furthermore, a guide hole is provided inside the second positioning block 61, and the cross section of the guide hole is a right-angle trapezoid. Figure 5 As shown, this structure is used to shrink the flushing tube 405 or the suction tube 406 into the rigid tube 2 through the guide hole inside the second positioning block 61 when the flushing tube 405 or the suction tube 406 is reset.

[0033] Working principle: When used, Figure 1 As shown, according to the patient's nasal cavity condition, the rigid tube 2 is placed in the nasopharynx through the nostrils, and then an appropriate amount of gas is injected into the inflation bag 7 to prevent the end of the rigid tube 2 from accidentally touching the nasopharyngeal skin, as shown in FIG. Figure 2 and Figure 3 As shown, when flushing is required, the first positioning block 503 corresponding to the flushing tube 405 is pulled, and the flushing tube 405 is driven to move downward along the first slide groove 504 through the connecting rod 502, so that the end of the flushing tube 405 extends out from the rigid tube 2, and the physiological saline passes through the flushing tube 405 to flush the endoscope lens 3. When suction is required, the flushing tube 405 is reset, and the first positioning block 503 corresponding to the suction tube 406 is pulled, and the suction tube 406 is driven to move downward along the first slide groove 504 through the connecting rod 502, so that the end of the suction tube 406 extends out from the rigid tube 2 to keep the surgical cavity clean. At the same time, the first positioning block 503 can be rotated along the second slide groove 507 to adjust the angle of the flushing tube 405 or the suction tube 406 to expand the contact area. Figure 5 As shown, when the flushing tube 405 and the suction tube 406 move, they move along the second positioning block 61 through the guide tube 62 and the guide block 63. When the flushing tube 405 or the suction tube 406 is reset, the flushing tube 405 and the suction tube 406 are retracted into the rigid tube 2 through the guide hole at the second positioning block 61. The above is the entire working principle of the present invention.
