[0002] Glaucoma is a group of diseases characterized by optic disc atrophy and depression, visual field loss, and decreased vision. Pathologically elevated intraocular pressure and insufficient blood supply to the optic nerve are primary risk factors for its development. The optic nerve's tolerance to pressure damage is also associated with the onset and progression of glaucoma. Any obstruction in the aqueous humor circulation pathway can lead to elevated intraocular pressure and pathological changes, but some patients also present with normal-tension glaucoma.

During the existing operation, the patient is required to keep his eyes open, which can easily cause visual fatigue over time and interfere with the performance of the operation. At the same time, the needle hole and the catheter are not on the same device. During the operation, the assistant needs to hand it to the attending doctor to replace the different devices, which is more troublesome.

By setting the positioning plate 919, the water supply pipe 904 is positioned and fixed. By setting the water supply pipe 904, the movement of the pressure plate 901 is coordinated to perform the extraction, adsorption and decompression operation of the iris eyeball water chamber.
[0051] The working principle of the present invention is as follows: a glaucoma aqueous humor drainage tube implant push injection device, when using, the user first sticks the lower surface of the adhesive patch 7 on the surface of the patient's eyelid. After the contact is stable, the operator rotates the first knob 906. The rotation of the first knob 906 drives the one-way screw 908 to rotate. The rotation of the one-way screw 908 applies pressure to the second column 910 through the sliding adjustment of the slide plate, so that the sliding plate 912 slides and adjusts in the adjustment cylinder 911. The sliding plate 912 applies force to the first column 909, driving the right clamp 5 to fix The column 3 is rotated as the axis, and the second column 910 drives the left clamping plate 4 to rotate with the fixed column 3 as the axis. The movement of the left clamping plate 4 and the right clamping plate 5 makes a pair of contact plates 6 open to each other, realizing the tension support of the patient's eyelid. Then the operator rotates the adjusting drum 2, and the rotation of the adjusting drum 2 drives the threaded column 916 to move downward. The movement of the threaded column 916 drives the sliding rod 917 and the needle head 918 to move as a whole. The needle head 918 passes through the guide head 905 to realize the iris puncture operation of the human body. After the puncture is completed, the adjusting drum is rotated in the opposite direction. The rotary drum 2 is used to store the needle 918, and then the operator rotates the spur gear 914. Since the rack 915 is engaged with the spur gear 914, the spur gear 914 rotates to drive the rack 915 and the adjusting lower shell 8 to move as a whole, so that the adjusting lower shell 8 slides down until the lower surface of the guide head 905 contacts the puncture site of the patient's iris. Then the operator rotates the second knob 920, and the rotation of the second knob 920 drives the forward and reverse screw rods 923 to rotate. The rotation of the forward and reverse screw rods 923 drives the pair of L-shaped plates 903 to move away from each other, and the L-shaped plates 90 3. The movement drives the pressure plate 901 to move and reset, and the reset spring 921 assists the pair of pressure plates 901 to move and reset, driving the reset spring 921 to stretch and lengthen. In this process, the space between the two pressure plates 901 becomes larger, and the water supply pipe 904 is used to pump the patient's iris aqueous humor into the pressure box 902 to reduce the pressure on the glaucoma. With the above structure, the patient's eyelids are supported and tensioned during the operation to maintain stability. At the same time, the needle puncture and aqueous humor diversion and decompression equipment are centralized to avoid frequent replacement of the equipment during the operation.
