Problems solved by technology
However, since the crystal push needle and the pushing part of the injector are integrated or fixed, there will be obvious pressure on the inner wall of the crystal push needle and the introduction head, and there will be obvious frictional resistance from the device itself during the injection process. This large frictional resistance will increase the difficulty of the doctor's operation, which is not conducive to the smooth completion of the operation.
Moreover, during the whole injection process, there is a large friction between the metal crystal push needle and the plastic introduction head, which may cause debris to fall off the introduction head, increasing the risk during the operation.

Embodiment Construction
[0080] The following description of one or more embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
[0081] like Image 6 As shown, the pushing part of the crystal push pin floating type intraocular lens injector of the present invention is divided into two parts: the crystal push pin and the connecting rod. The crystal push pin and connecting rod are separate parts that can be disassembled, and the crystal pushing pin and connecting rod can be connected together by a floating device.
[0082] The floating device may be a separate element that combines the crystal push pin and the connecting rod together and allows the crystal push pin to float up and down. The floating device can also be a part integrally formed with the connecting rod. For example, the floating device can be provided at the front end of the connecting rod by opening holes or digging grooves on the connecting rod. Alternatively or additional...

The invention relates to a floating artificial crystal injector for a crystal push needle. The intraocular lens injector includes: a connecting rod, which is used to be pushed during the injection process, thereby pushing the crystal push pin; Under the promotion of the artificial lens, the artificial lens is pushed; and the floating device is used to connect the crystal push pin and the connecting rod together, and the floating device is used to make the crystal push pin float up and down within a certain range.
Description
technical field [0001] The present invention mainly relates to intraocular lens implanters. More specifically, the present invention relates to a floating type intraocular lens injector with a lens push pin. Background technique [0002] An intraocular lens is an artificial lens that can be implanted in the eye and is used in eye surgery. For example, in cataract surgery, the technique of replacing the natural lens in a person's eye clouded by cataract disease by implanting an artificial lens has been widely practiced. The shape of an intraocular lens usually consists of a central circular optic and peripheral haptics. Due to the different materials for processing intraocular lenses, intraocular lenses are divided into hard intraocular lenses whose optics are made of hard materials such as PMMA, and soft IOLs whose optics are made of flexible materials such as silicon elastomers, hydrogels, and soft acrylates. crystals. IOLs made of soft materials are also often called c...
