Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely is a kind of artificial crystal fixing mechanism. BACKGROUND

[0002] During treatment, artificial crystal needs to be cut in eye and taken out piece by piece. Currently, during cutting artificial crystal, it is common to use position hook to fix artificial crystal, but because auxiliary incision is relatively small, position hook cannot flexibly and multi-directionally firmly fix artificial crystal, leading to artificial crystal sliding during cutting, and damaging surrounding tissue.

[0003] For example, application No. CN202022263545.5, "artificial crystal fixator", includes a crystal pad and a crystal pad operation handle fixed integrally with the crystal pad, a crystal pad operation handle is installed on the crystal pad operation handle through a hinged connection device, and a crystal pad is integrally fixed on the crystal pad operation handle corresponding to the crystal pad. The crystal pad and the crystal pad described in the patent have a larger contact area with the artificial crystal, which can make the fixation more reliable, but the size of the artificial crystal after cutting is often inconsistent, and the fixation effect is different when fixing different size crystal pieces, especially when clamping obviously smaller pieces.

[0004] To solve the above problems, the present case arises. SUMMARY

[0005] Technical problem solved

[0006] The utility model aims at providing a kind of artificial crystal fixing mechanism, to solve the problems raised in the above background technology.

[0007] Technical scheme

[0008] To achieve the above purpose, the utility model is realized by the following technical scheme: a kind of artificial crystal fixing mechanism, including upper operation handle and lower operation handle, the upper operation handle and lower operation handle are hinged, the lower end of the upper operation handle is equipped with crystal pad, the lower end of the lower operation handle is equipped with base, the base is equipped with shaft on both sides, the base is equipped with crystal pad, the crystal pad is equipped with two pieces and is set on base left and right, the two pieces of crystal pad are fixedly connected with the shaft of base on both sides respectively.

[0009] Preferably, the shaft is rotatably connected with the base, the upper end surface of the upper operation handle is rotatably connected with a roller, and the drive line is connected between the roller and the shaft, and the two ends of the drive line are wound on the roller and the shaft respectively.

[0010] Preferably, the base is provided with a guide block at the center, the guide block extends beyond the base, and there is a gap between the guide block and the base.

[0011] Preferably, the lower end face of the die is provided with a protrusion, which faces the guide block. Beneficial effects

[0012] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: The artificial lens fixing mechanism of this utility model sets the pad chip as two rotatable pieces. The angle between the pad chip changes, which is conducive to "scooping up" chips of different sizes, making the fixing effect better and facilitating the removal of cut crystal fragments.
