The tears remaining on the inner wall of the tear collection seat are automatically scraped off to ensure that the tears are completely collected to avoid omissions, which helps to improve the efficiency and accuracy of tear collection. At the same time, the function of automatically scraping off tears can simplify the surgical process and reduce the steps that doctors need to manually handle tears during the operation, which helps doctors focus more on the surgical operation itself and improves the success rate and efficiency of the operation.

The first expansion clamp 12 and the second expansion clamp 121 can be pulled, and the inner parts of the first expansion clamp 12 and the second expansion clamp 121 can contact the patient's eyelid parts respectively. At this time, the second expansion clamp 121 and the first expansion clamp 12 both rotate around the connection position with the auxiliary device body 11, and at the same time, the two groups of inner push plates 21 respectively rotating on the second expansion clamp 121 and the first expansion clamp 12 rotate around the connection position with the connecting piece 221 at the same time, thereby driving the inner sliding plate fixed at the bottom end of the connecting piece 221 The seat 22 slides inside the auxiliary device body 11, and the sliding of the inner sliding seat 22 can drive the pushing rotating plate 23 connected to it to rotate around the connection position with the main rotating rod 24, and then drive the main rotating rod 24 to rotate around the connection position with the auxiliary device body 11.

At this time, the square bar 32 slidably connected to the inside of the U-shaped slide 31 can move simultaneously with the sliding of the U-shaped slide 31, and the transmission sliders 321 fixed on both sides of the square bar 32 can slide inside the guide groove 351 opened on the guide plate 35. With the continuous sliding of the U-shaped slide 31, the transmission slider 321 can slide from the smooth groove to the inside of the inclined groove. At the same time, under the connection of the connecting rod 33, the transmission sliders 321 fixed on the two transmission sliders 321 can slide from the smooth groove to the inside of the inclined groove. The bottom end of the scraper body 34 can be separated from the bottom end of the inner wall of the tear collecting seat 25 to facilitate the entry of the patient's tears. During the disassembly of the auxiliary device body 11, the side slider 261 can slide to the right, and the two transmission sliders 321 can enter the smooth groove from the inside of the inclined slide groove, so that the bottom end of the scraper body 34 contacts the bottom end of the inner wall of the tear collecting seat 25. As the U-shaped slide 31 continues to move, the transmission slider 321 can be driven to continue to slide inside the smooth groove. At this time, the scraper body 34 can scrape and collect the tears remaining at the bottom end of the inner wall of the tear collecting seat 25.

[0025] The limiting assembly 4 includes a telescopic fixing seat 41 fixed on the auxiliary device body 11, a telescopic rod 42 is inserted into the telescopic fixing seat 41, an arc-shaped limiting rod 44 is fixedly provided on the telescopic rod 42, two groups of limiting teeth 45 are fixedly provided on the arc-shaped limiting rod 44, and limiting protrusions 46 in contact with the two groups of limiting teeth 45 are fixedly provided on the top of the first expansion clamp 12 and the second expansion clamp 121 respectively.

[0027] In the process of limiting the patient's eyelids, the telescopic rod 42 can be pushed to separate the multiple limiting teeth 45 fixed on the arc-shaped limiting rod 44 from the two limiting protrusions 46. In this process, the reset spring 43 sleeved on the telescopic rod 42 can be compressed, and the first expansion clamp 12 and the second expansion clamp 121 are pulled respectively, and the first expansion clamp 12 and the second expansion clamp 121 are respectively rotated around the connection position with the auxiliary device body 11, and the torsion spring fixed between the first expansion clamp 12 and the second expansion clamp 121 can be compressed.

The torsion spring between the tension clamps 121 makes the inner side parts of the first expansion clamp 12 and the second expansion clamp 121 contact the patient's eyelid part respectively, and at the same time drives the two groups of inner push plates 21 respectively rotating on the second expansion clamp 121 and the first expansion clamp 12 to rotate around the connection position with the connecting piece 221 at the same time, thereby driving the inner sliding seat 22 fixed at the bottom end of the connecting piece 221 to slide inside the auxiliary device body 11, and the sliding of the inner sliding seat 22 can drive the pushing rotating plate 23 connected to it to rotate around the connection position with the main rotating rod 24, and then drive the main rotating rod 24 to rotate around the connection position with the auxiliary device body 11. At the same time, the rotation of the main rotating rod 24 can drive the tear collecting seat 25 rotating at the bottom end of the main rotating rod 24 to make a circular motion, and at the same time pull The top end of the rod 26 can rotate around the inner wall of the protective seat 13, and the two side sliders 261 fixed at the other end of the pull rod 26 can slide inside the movable slide groove, so that the soft silicone material at the bottom end of the tear collection seat 25 can fit the position of the patient's eye corner, and the cooperation between the tear collection seat 25 and the magnetic tear bag 36 can collect the tears produced by the patient during the operation. At the same time, the two side sliders 261 can slide to the left, and then drive the U-shaped slide seat 31 fixed on the two side sliders 261 to slide. At this time, the square bar 32 slidably connected to the inside of the U-shaped slide seat 31 can move simultaneously with the sliding of the U-shaped slide seat 31, and the transmission sliders 321 fixed on both sides of the square bar 32 can slide inside the guide groove 351 opened on the guide plate 35. The continuous sliding of the U-shaped slide block 321 can make the transmission slide block 321 slide from the smooth groove to the inside of the inclined groove. At the same time, under the connection of the connecting rod 33, the bottom end of the scraper body 34 fixed on the two transmission slide blocks 321 can be separated from the bottom end of the inner wall of the tear collection seat 25, so as to facilitate the entry of the patient's tears. In the process of disassembling the auxiliary device body 11, the side slide block 261 can slide to the right, and the two transmission slide blocks 321 can enter the smooth groove from the inside of the inclined groove, so that the bottom end of the scraper body 34 contacts the bottom end of the inner wall of the tear collection seat 25. With the continuous movement of the U-shaped slide block 31, the transmission slide block 321 can be driven to slide continuously in the smooth groove. At this time, the scraper body 34 can scrape and collect the tears remaining at the bottom end of the inner wall of the tear collection seat 25.When the positions of the first expansion clamp 12 and the second expansion clamp 121 are adjusted to the desired positions, the telescopic rod 42 can be loosened. At this time, under the elastic force of the return spring 43, the limiting teeth 45 on the arc-shaped limiting rod 44 contact with the limiting protrusions 46 on the first expansion clamp 12 and the second expansion clamp 121, which can achieve the purpose of limiting.
