[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] like Figures 1 to 7As shown, a conjunctival sac irrigation support includes a base plate 1, four support legs 2 connected to the base plate 1, a seat 3 mounted on the support legs 2, a backrest 4 rotatably mounted on the seat 3, a sliding groove 5 on the backrest 4, a connecting rod 6 slidably mounted in the sliding groove 5, a lead screw sleeve 7 connected to the end of the connecting rod 6, a lead screw shaft 8 engaged in the lead screw sleeve 7, an installation rod 9 mounted on the lead screw shaft 8, a square groove 10 on the installation rod 9, a sliding rod 11 slidably mounted in the square groove 10, one end of the sliding rod 11 connected to a shelf 12, and the other end connected to the lead screw sleeve 7. In this setup, the base plate 1 is the basic supporting component of the entire device. The support leg 2 connects the base plate 1 to the seat 3, which is for the patient to sit on. The backrest 4 is the part for the patient to lean against and is angle-adjustable. The slide groove 5 provides a moving track for the connecting rod 6, and they work together to adjust the angle of the backrest 4. The lead screw sleeve 7 meshes with the lead screw shaft 8, converting the rotational motion of the lead screw shaft 8 into its own linear motion, thereby driving the connecting rod 6, slide rod 11, and other components to move. The mounting rod 9 is used to install the lead screw shaft 8. The square groove 10 provides support for the sliding of the slide rod 11. When the lead screw sleeve 7 moves, the slide rod 11 drives the placement plate 12 to move along the square groove 10, adjusting the position of the placement plate 12. The placement plate 12 is used to place ophthalmic tools, making it convenient for doctors to access them during the rinsing process. Its position can be changed according to the angle adjustment of the backrest 4.

[0027] like Figures 1 to 7 As shown, in a specific embodiment, a universal shaped metal hose 13 is connected to the backrest 4. A ring frame 14 is connected to the end of the universal shaped metal hose 13. A through-tube groove 15 is provided on the ring frame 14. A water receiver 16 is installed on the ring frame 14. A guide tube 17 is connected to the bottom of the water receiver 16. A collection bucket 18 is connected to the end of the guide tube 17 and is placed on the base plate 1. In this configuration, the universal shaped metal hose 13 can be bent and shaped arbitrarily to adjust the position of the ring frame 14 and the water receiver 16, ensuring that the water receiver 16 is accurately aligned with the area below the patient's eye. The ring frame 14 houses the water receiver 16, and the through-tube groove 15 facilitates the passage of the guide tube 17 through the ring frame 14, thus facilitating the installation of the water receiver 16. The water receiver 16 receives the liquid generated from rinsing the conjunctival sac, preventing liquid splashing. The guide tube 17 guides the rinsing fluid collected by the water receiver 16 to the collection bucket 18, achieving centralized collection of waste liquid.

[0028] like Figures 1 to 7 As shown, a handwheel 19 is further installed at the end of the lead screw shaft 8. In this configuration, the handwheel 19 is installed at the end of the lead screw shaft 8, and the doctor can easily drive the lead screw shaft 8 to rotate by turning the handwheel 19, thereby adjusting the various components of the device.

[0029] like Figures 1 to 7As shown, a rotating rod 22 is rotatably mounted on the connecting rod 6, and the rotating rod 22 is installed in the slide groove 5. In this configuration, the rotating rod 22 connects the connecting rod 6 to the slide groove 5 on the backrest 4. When the connecting rod 6 moves, it rotates in the slide groove 5, assisting the connecting rod 6 to move smoothly, and at the same time cooperating to realize the angle adjustment of the backrest 4.

[0030] like Figures 1 to 7 As shown, a head placement slot 21 is provided on the backrest 4. In this configuration, the head placement slot 21 is located on the backrest 4 to fix the patient's head, prevent the patient's head from moving during the rinsing process, ensure the accuracy and safety of the rinsing operation, and at the same time prevent the cleaning solution from flowing onto the patient's hair or clothes.

[0031] like Figures 1 to 7 As shown, casters 20 are installed at the bottom of the base plate 1. In this configuration, the casters 20 are installed at the bottom of the base plate 1 to facilitate the adjustment of the device position, and the casters 20 have a locking function to prevent the device from moving accidentally.

[0032] The implementation principle of the conjunctival sac irrigation stent in this embodiment is as follows: In use, the stent is first easily moved to a suitable position using the casters 20 at the bottom of the base plate 1. The doctor determines whether the patient should be seated or lying down based on their specific condition. If the backrest 4 needs adjustment, the doctor can rotate the handwheel 19 at the end of the lead screw shaft 8. Since the lead screw shaft 8 and the lead screw sleeve 7 mesh with each other, this will cause the lead screw sleeve 7 to move along the lead screw shaft 8. During the movement, the lead screw sleeve 7 will drive the connecting rod 6 connected to it. The rotating rod 22 rotatably mounted on the connecting rod 6 plays a cooperating role in the sliding groove 5 of the backrest 4, ensuring smooth and stable movement of the connecting rod 6. It is worth noting that when the lead screw sleeve 7 moves, through the mutual cooperation between the connecting rod 6, the rotating rod 22, and the sliding groove 5, not only can the connecting rod 6 move up and down, but the backrest 4 can also rotate around its connection point with the seat 3. Simultaneously, the movement of the lead screw sleeve 7 will also cause the sliding rod 11 to slide in the square groove 10 of the mounting rod 9, thereby allowing the shelf 12 to reach the ideal position. The backrest 4 is positioned to facilitate the placement of various ophthalmic tools. When the lead screw sleeve 7 moves downward, the connecting rod 6 and the rotating rod 22 move accordingly within the slide groove 5, and the backrest 4 gradually changes from its initial angle to a flat position. During this process, the slide rod 11 moves downward with the lead screw sleeve 7, and the placement plate 12 also descends. This allows doctors to easily access tools without having to frequently move up and down to retrieve them. After the patient adjusts their posture, they place their head in the head placement slot 21 of the backrest 4. This effectively prevents the patient from moving their head unconsciously during the rinsing process. Head movement not only affects the rinsing effect but also causes the cleaning fluid to flow onto clothing. When rinsing the conjunctival sac, the doctor can flexibly bend the universal shaped metal hose 13 to precisely adjust the position of the ring frame 14, ensuring that the water receiver 16 is aligned precisely below the patient's eye. The rinsing fluid flows into the water receiver 16 and then into the collection bucket 18 placed on the base plate 1 via the guide tube 17. This completes the entire conjunctival sac rinsing process.
