Capsule tearing assisting device for centrally positioning capsule bag

Abstract

The invention discloses a capsule tearing assisting device for centrally positioning a capsule bag. The device comprises a cornea imprint ring (1) which is connected to a dial disc (2) through connecting rods (3), the cornea imprint ring (1) is concentric to the dial disc (2), and 360 degree scales are marked on the dial disc (2). Length based on mm is marked on the connecting rods (3). The dial disc (2) is connected to a bent transitional handle (4) (the angle is about 145 degrees). The transitional handle (4) is connected to a handle (5). The two connecting rods (3) are crossed, and the crosspoint of the connecting rods is the center of circle of the cornea imprint ring (1). By adopting a design concept that the dial disc and the cornea imprint ring are combined, the central position ofthe capsule bag of a patient can be positioned precisely according to the actual eye anatomical structure of the patient. CCC guide is carried out by using the cornea imprint ring, and the central property of the capsule bag of CCC is achieved finally, so that the operative accuracy and the postoperative effect are improved.

Description

technical field [0001] The invention relates to the field of medical and health care, in particular to an instrument that combines the positioning of the center of the capsular bag and the auxiliary function of capsulorhexis related to ophthalmic cataract surgery. Background technique [0002] Cataract is the world's first blinding eye disease, and surgery is currently recognized as the only effective treatment. With the continuous advancement of technology, cataract surgery methods are also changing. However, no matter which cataract surgery method is adopted, capsulorhexis is one of the most critical steps in the operation. With the advent of high-end intraocular lenses (IOLs) such as trifocal IOLs and infinite zoom IOLs with diffractive rings and scattering rings in recent years, maintaining the good centering of the capsular bag of the implanted IOL is used to reduce the adverse vision of patients after surgery Quality (for example: starburst, halo, glare, etc.) is par...

AI Technical Summary

Problems solved by technology

[0003] At present, many cataract surgeons have eccentric capsulorhexis due to lack of experience. Even with the help of existing auxiliary equipment, it is difficult to achieve a satisfactory centered CCC in the capsular bag, which leads to the inability of the IOL to cover the entire circumference evenly, and eventually leads to the possibility of high-end IOL implantation. Occurs poor visual quality and increases the incidence of PCO, so the object of the present invention is to provide a capsulorhexis assisting device for centering of the capsular bag
