Description

Technical Field

[0001] The utility model relates to the technical field of clamping forceps, in particular to a novel ICL clamping forceps. Background Art

[0002] ICL implantation is one of the mainstream surgical procedures for correcting refractive errors (myopia and astigmatism). The correction principle is to make a 2.75mm-3mm micro-incision at the edge of the cornea, and implant an artificial lens made of special materials into the posterior chamber of the eye (the gap between the iris and the lens itself) through the incision to correct refractive errors. Clamping forceps are required when implanting and removing the ICL.

[0003] After searching, the application with patent number 202120789981.8 discloses a pair of tweezers for clamping intraocular lens haptics, comprising a connector and clamping pieces symmetrically arranged on both sides of the connector, wherein a semicircular groove is provided on the inner side of the clamping piece away from the end of the connector;

[0004] Although the tweezers used to clamp the intraocular lens haptic have a semicircular groove on the inner side of the clamping piece away from the end of the connector that matches the size of the intraocular lens haptic to prevent deformation of the lens haptic during clamping, the tip of the tweezers used to clamp the intraocular lens haptic is sharp and can easily scratch the ICL, and the angle at which the tip of the tweezers is opened is large, which can easily cause the incision to be stretched.

[0005] Therefore, we proposed a new ICL clamping forceps. Utility Model Content

[0016] The utility model provides a new type of ICL clamping forceps, which has the following beneficial effects:

[0017] The new ICL clamping forceps, by setting the clamping plate in the shape of a flat plate with smooth edges, can make the contact area between the clamping plate and the ICL larger, and the surface of the ICL is evenly stressed, which can prevent the ICL from being scratched or scratching the patient, and is safer to use. The two clamping rods open and close inside the round tube, which can drive the two clamping plates to move in parallel. The two clamping plates always remain parallel to each other, and will not significantly stretch the incision in the eye, which has little impact on the eye, making the operation safer and simpler to use. It solves the problems of the existing device with a sharp head end that can easily scratch the ICL and a large angle of the tweezers head end that can easily cause the incision to be stretched. The new ICL clamping forceps can be used during ICL surgery. If the ICL flips during the operation, the clamping forceps can be used to safely remove the ICL and then implant it into the eye. It can also be used during ICL replacement or removal surgery to safely remove the ICL. In addition, the clamping forceps can also be used when an artificial lens needs to be removed or replaced after cataract surgery. BRIEF DESCRIPTION OF THE DRAWINGS
