Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] In related technologies, intraocular lenses (IOLs) require high surface quality and processing precision, which is fundamentally different from the processing requirements of traditional mechanical parts. During the machining of IOLs, the IOL is adhered to the base using water-soluble wax. After machining, ultrasonic cleaning is used to melt the water-soluble wax, allowing the IOL to separate from the base. However, this separation process can easily damage the surface of the IOL, leading to a lower yield rate.

[0022] Reference Figures 1 to 4 This utility model discloses a fixture for cleaning an intraocular lens, comprising a mounting assembly 100, a limiting plate 200, and a cover plate 300. The mounting assembly 100 includes a fixing base 110 and a mounting base 120 connected to the fixing base 110. The mounting base 120 is used to mount an intraocular lens 500. The limiting plate 200 has a through hole 210 and is rotatably connected to the fixing base 110 so that the mounting base 120 can enter or exit the through hole 210. The cover plate 300 has a receiving groove 310 and is rotatably connected to the limiting plate 200 so that the fixture for cleaning the intraocular lens can be in a folded state or an unfolded state. When the fixture for cleaning the intraocular lens is in the folded state, the mounting base 100... At least a portion of the 20 is housed within the through hole 210, the cover plate 300 covers the through hole 210, and the receiving groove 310 communicates with the through hole 210 so that the receiving groove 310 can accommodate the intraocular lens 500 separated from the mounting base 120. Thus, the through hole 210 can guide and limit the intraocular lens 500 that has fallen off the mounting base 120, preventing the intraocular lens 500 from moving laterally and scratching during the separation process. Moreover, the receiving groove 310 can safely accommodate the detached intraocular lens 500, preventing the detached intraocular lens 500 from rolling and colliding freely in the ultrasonic cleaning chamber, and preventing the surface of the intraocular lens 500 from being damaged during cleaning, thereby improving the yield of the intraocular lens 500.

[0023] For example, when cleaning the intraocular lens 500, the limiting plate 200 and the cover plate 300 are rotated to fold the clamp used for cleaning the intraocular lens. The clamp is then placed in the ultrasonic cleaning chamber. After the water-soluble wax melts, the intraocular lens 500 falls into the receiving groove 310 through the through hole 210. Then, the cover plate 300 is rotated in the opposite direction to switch the clamp from the folded state to the unfolded state, allowing the intraocular lens to be removed from the receiving groove 310. The lens 500 and the through hole 210 can guide and limit the intraocular lens 500 that has fallen off the mounting base 120, preventing the intraocular lens 500 from moving laterally and scratching during the separation process. In addition, the receiving groove 310 can safely hold the fallen intraocular lens 500, preventing it from rolling and colliding freely in the ultrasonic cleaning chamber. This can prevent the surface of the intraocular lens 500 from being damaged during cleaning, thereby improving the yield of the intraocular lens 500.

[0024] In this embodiment, multiple mounting bases 120 are configured, and the multiple mounting bases 120 are arranged side by side at intervals along the length direction of the fixing base 110. Multiple through holes 210 and receiving grooves 310 are configured accordingly, which can fix multiple artificial lenses 500 at the same time and clean multiple artificial lenses 500 at the same time, thereby improving the cleaning efficiency of artificial lenses 500.

[0025] For example, the fixing seat 110 is a long strip structure, and the number of mounting seats 120, through holes 210 and receiving grooves 310 are equal. By setting multiple mounting seats 120, through holes 210 and receiving grooves 310 side by side, the fixture used for cleaning artificial lenses can simultaneously complete the fixing, guiding, separation and receiving processes of multiple artificial lenses 500, thereby improving the cleaning efficiency of artificial lenses 500.

[0026] It should be noted that there may be one additional mounting bracket 120; this is not a limitation.

[0027] In this embodiment, the cover plate 300 is provided with a first opening 320 that connects to the receiving groove 310, so that the cleaning fluid in the ultrasonic cleaning chamber can enter the through hole 210 through the first opening 320, which can accelerate the dissolution rate of water-soluble wax and thus improve the cleaning efficiency of the artificial lens 500.

[0028] Understandably, by setting the first opening 320, the cleaning fluid can freely flow into and out of the receiving tank 310, which can prevent the formation of stagnant water in the receiving tank 310 and ensure that the dissolved wax debris can be carried away in time, thereby improving the cleaning effect of the artificial lens 500.

[0029] In this embodiment, the limiting plate 200 is provided with a second opening 220 that connects to the through hole 210, so that the cleaning fluid in the ultrasonic cleaning chamber can enter the through hole 210 through the second opening 220, which can accelerate the dissolution rate of water-soluble wax and thus improve the cleaning efficiency of the artificial lens 500.

[0030] In this embodiment, along the width direction of the limiting plate 200, a first connecting shaft 201 and a second connecting shaft 202 are respectively provided on opposite sides of the limiting plate 200. The fixing seat 110 is rotatably connected to the limiting plate 200 through the first connecting shaft 201, and the cover plate 300 is rotatably connected to the limiting plate 200 through the second connecting shaft 202. This can avoid the movement interference between the limiting plate 200 and the cover plate 300, and ensure that the clamp used for cleaning the artificial lens moves smoothly and is accurately positioned during folding and unfolding, thereby facilitating user operation.

[0031] For example, a first connecting shaft 201 is provided on one side of the width direction of the limiting plate 200, and a second connecting shaft 202 is provided on the other side of the width direction of the limiting plate 200. This separates the rotation of the fixing seat 110 and the limiting plate 200, as well as the rotation of the cover plate 300 and the limiting plate 200, onto different axes. This makes the movement of the fixing seat 110, the limiting plate 200, and the cover plate 300 more independent and stable, avoids movement interference, and ensures that the clamp used for cleaning the intraocular lens moves smoothly and is accurately positioned during folding and unfolding, thereby improving the reliability and convenience of operation.

[0032] In another embodiment, the first connecting shaft 201 and the second connecting shaft 202 may also be located on the same side of the limiting plate 200, which is not a limitation.

[0033] In this embodiment, a first limiting structure is provided between the limiting plate 200 and the fixing seat 110. When the fixture for cleaning the intraocular lens is in a folded state, the first limiting structure is used to restrict the mounting seat 120 from exiting the through hole 210. This can effectively limit the relative rotation between the limiting plate 200 and the fixing seat 110, prevent the mounting seat 120 from accidentally exiting the through hole 210, and enhance the structural stability and safety of the fixture for cleaning the intraocular lens in the folded state.

[0034] In this embodiment, the first limiting structure includes a first magnet 250 disposed on the limiting plate 200 and a second magnet 111 disposed on the fixing seat 110. The first magnet 250 magnetically attracts the second magnet 111, which can effectively limit the relative rotation between the limiting plate 200 and the fixing seat 110, prevent the mounting seat 120 from accidentally exiting the through hole 210, and enhance the structural stability and safety of the fixture for cleaning artificial lenses in the folded state.

[0035] For example, the first magnet 250 and the second magnet 111 have different magnetic properties. At least two of the first magnet 250 and the second magnet 111 are provided, and the number of the first magnet 250 and the second magnet 111 is equal. When the intraocular lens 500 is in a folded state, the first magnet 250 attracts the second magnet 111, which can effectively limit the relative rotation between the limiting plate 200 and the fixing seat 110, prevent the mounting seat 120 from accidentally exiting the through hole 210, and enhance the structural stability and safety of the fixture for cleaning the intraocular lens in the folded state.

[0036] As another implementation, the first limiting structure can also be a structure in which a hook and a slot cooperate. For example, the hook is provided on the fixed seat 110 and the slot is provided on the limiting groove. When the artificial lens 500 is in a folded state for cleaning, the hook part of the hook engages with the side wall of the slot, which can also limit the relative rotation between the limiting plate 200 and the fixed seat 110. This is not limited here.

[0037] In this embodiment, a second limiting structure is provided between the limiting plate 200 and the cover plate 300. When the fixture for cleaning the intraocular lens is in a folded state, the second limiting structure is used to restrict the cover plate 300 from rotating in a direction away from the through hole 210. This can effectively restrict the relative rotation between the limiting plate 200 and the cover plate 300, prevent the cover plate 300 from opening the through hole 210, and enhance the structural stability and safety of the fixture for cleaning the intraocular lens in the folded state.

[0038] In this embodiment, the second limiting structure includes a third magnet 260 disposed on the limiting plate 200 and a fourth magnet 330 disposed on the cover plate 300. The third magnet 260 magnetically attracts the fourth magnet 330, which can effectively limit the relative rotation between the limiting plate 200 and the cover plate 300, prevent the cover plate 300 from opening the through hole 210, and enhance the structural stability and safety of the fixture used for cleaning the intraocular lens in the folded state.

[0039] For example, the third magnet 260 and the fourth magnet 330 have different magnetic properties, and at least two of each are provided. The number of third magnets 260 and fourth magnets 330 is equal. When the intraocular lens 500 is in a folded state, the third magnet 260 magnetically attracts the fourth magnet 330, which can effectively limit the relative rotation between the limiting plate 200 and the cover plate 300, prevent the cover plate 300 from opening the through hole 210, and enhance the structural stability and safety of the clamp for cleaning the intraocular lens in the folded state.

[0040] As another implementation method, the second limiting structure can also be a structure in which a hook and a slot cooperate, which will not be described in detail here.

[0041] It is understandable that, in order to keep the clamp used for cleaning the intraocular lens stably in a folded state, a third limiting structure can be provided between the fixing seat 110 and the cover plate 300, without the need to provide a first limiting structure between the fixing seat 110 and the limiting plate 200, or a second limiting structure between the cover plate 300 and the limiting plate 200. The third limiting structure can be a structure in which a hook and a slot cooperate, which will not be described in detail here.

[0042] Reference Figure 5 , Figure 6 In this embodiment, the fixture for cleaning the intraocular lens also includes a support assembly 400. The support assembly 400 includes a first connecting frame 410, a second connecting frame 420, and a support member 430. The support member 430 is connected between the first connecting frame 410 and the second connecting frame 420. The first connecting frame 410 and the second connecting frame 420 are arranged opposite to each other. The side of the cover plate 300 away from the limiting plate 200 abuts against the support member 430. The first connecting frame 410 and the second connecting frame 420 can abut against the table surface of the ultrasonic cleaning chamber to facilitate the user to remove the fixture for cleaning the intraocular lens.

[0043] For example, when the clamp for cleaning the intraocular lens is in a folded state, the maximum vertical distance between the fixing base 110 and the cover plate 300 is less than the vertical dimension of the first connecting frame 410 or the second connecting frame 420. When cleaning the intraocular lens 500, the intraocular lens 500 is completely immersed in the cleaning solution, while the first connecting frame 410 and the second connecting frame 420 are only partially immersed in the cleaning solution. The end of the first connecting frame 410 away from the support member 430 and the end of the second connecting member away from the support member 430 abut against the table surface of the ultrasonic cleaning chamber, which makes it convenient for the user to remove the clamp for cleaning the intraocular lens.

[0044] In this embodiment, the first connecting frame 410 is provided with a first limiting hole 411, the second connecting frame 420 is provided with a second limiting hole 421, and the two ends of the limiting plate 200 are respectively provided with a first limiting protrusion 230 and a second limiting protrusion 240. The first limiting protrusion 230 is accommodated in the first limiting hole 411 and abuts against the side wall of the first limiting protrusion 230. The second limiting protrusion 240 is accommodated in the second limiting hole 421 and abuts against the side wall of the second limiting protrusion 240. This can prevent the limiting plate 200 from moving during the cleaning process and position the limiting plate 200 in the ultrasonic cleaning chamber.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
