[0001] The utility model relates to the field of medical ophthalmic instruments, in particular to a corneal stroma lens processing dish. Background Art

[0002] Femtosecond laser small incision lenticule extraction (SMILE) has become widely used clinically and has achieved excellent results in myopia correction. With the increasing use of SMILE procedures, lenticules, as a byproduct of the procedure, have also been produced and processed in large quantities. Previously, these lenticules were discarded, a significant waste. In recent years, further research has led to their widespread application in hyperopia correction, keratoconus treatment, and the treatment of corneal diseases. Further processing and in-depth research on lenticules are ongoing.

[0003] In most cases, existing processing dishes adopt a single storage dish during use. The single storage dish is only set by a simple acrylic plate during use. It is not convenient to fix and take it during use, and it is not convenient to clean. As a result, it is necessary to use other equipment in conjunction with it during use. Therefore, a corneal stromal lens processing dish is proposed to solve the above problems.

[0004] With respect to the structure of the prior art, a single storage dish cannot achieve the effect of convenient fixed storage according to the use requirements, and a single storage dish is easy to allow dust to enter. It is also inconvenient to add the required materials during use, and other equipment is required during use, which affects work efficiency. Utility Model Content

[0005] In order to make up for the above deficiencies, the present invention provides a corneal stromal lens processing dish, which aims to improve the processing dishes in the prior art in terms of convenience for fixed storage, positioning, opening and closing, as well as convenience for disassembly and cleaning.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a corneal stroma lens processing dish, comprising a test tube rack, the test tube rack is slidably connected to a fixed shaft, the outer wall of the fixed shaft is fixedly connected to a limit plate, a first spring is provided inside the test tube rack, one end of the first spring is fixedly connected to the inside of the test tube rack, the other end of the first spring is fixedly connected to the outer wall of the limit plate, the outer wall of the fixed shaft is fixedly connected to a clamping rod, the interior of the test tube rack is provided with a placement slot, the interior of the test tube rack is slidably connected to a lower dish, the interior of the lower dish is provided with a slide slot, the interior of the lower dish is slidably connected to a card shaft, the card shaft is slidably connected to the interior of the slide slot, the upper surface of the card shaft is fixedly connected to an upper dish, the interior of the upper dish is provided with a hole, the interior of the lower dish is provided with a limit slot, and the interior of the card shaft is installed with a snap assembly for detachable assembly.
