Description

Technical Field

[0001] The utility model relates to the technical field of ophthalmic medical treatment, in particular to an integrated ICL artificial lens injector. Background Art

[0002] The ICL intraocular lens injector currently used in clinical practice consists of a guide sleeve and a push rod. The guide sleeve consists of two parts: a guide sleeve wing and a guide sleeve tube. The two parts are easy to separate after repeated use. If the two parts are separated during the process of injecting the intraocular lens during surgery, it is easy to increase the surgical risk for the patient. At the same time, the traditional push rod has no supporting position in the sleeve. During the injection process, the push rod is easy to shake left and right, causing instability in the injection.

[0003] Based on this, in order to solve the problems of the guide sleeve wing of the pusher falling off and the instability of the push rod, this design proposes an integrated ICL intraocular lens pusher. Utility Model Content

The guide tube 3 is cylindrical in structure, wherein the guide tube 3 and the guide tube wing 2 are an integrated structure, a circular limiting hole 31 is fixed inside the right end of the guide tube 3 for stabilizing the foam head piston 15, a cross limiting block 21 is arranged inside the guide tube wing 2, the integrated structure of the guide tube 3 and the guide tube wing 2 can ensure sufficient connection strength between the guide tube 3 and the guide tube wing 2, and separation will not occur due to the connection relationship between the two, the cross-sectional structure of the tube head 4 at the right end of the guide tube 3 is a trapezoidal structure, and the internal structure changes from large to small, which can continuously limit the push rod 1 and improve the accuracy of push injection, and the tube head 4 is equipped with a push chuck 6, which is used to carry the ICL crystal to be injected.

[0026] according to Figure 3 As shown, specifically, a spring 5 is installed inside the guide tube wing 2, one end of the spring 5 is pressed against the right end inside the guide tube wing 2, and the other end of the spring 5 is pressed against the push rod 1. The spring 5 can bring a certain damping feeling to the push rod 1 through its own elasticity, helping the doctor to improve the operation stability during the process of pushing the push rod 1.
