Description

Technical Field

[0001] The utility model relates to the technical field of capsule polishers, in particular to an injection and suction capsule polisher used in cataract surgery. Background Art

[0002] Senile cataract is a common and frequently-occurring disease in ophthalmology. With the advent of aging society, the number of cataract patients is increasing day by day. As the world's leading cause of blindness, there are many treatment methods, but surgery is still recognized as the only effective treatment. With the continuous advancement of science and technology, the surgical methods of cataract have also changed greatly. Precision and minimally invasive are the pursuit of clinicians, from "recovery surgery" to "refractive surgery". In recent years, various high-end refractive intraocular lenses have been widely used in clinical practice, such as: multifocal intraocular lenses, continuous visual range intraocular lenses and other intraocular lenses with presbyopia correction function, which have greatly improved the patient's postoperative visual quality. One of the main causes of postoperative visual loss is secondary cataract, the incidence of which is over 50%. How to reduce or avoid the occurrence of secondary cataract is particularly important.

[0003] There are many methods to prevent after-cataracts, such as improving the design and material of artificial lenses, adding heparin to the surface of the lens, and even directly performing posterior capsulectomy during surgery. However, the most commonly used method is to use various polishers to polish the anterior and posterior capsules during surgery to reduce the occurrence of postoperative after-cataracts. How to safely, fully, and efficiently polish the posterior capsule of the lens during surgery is directly related to the close fit between the artificial lens and the posterior capsule during surgery and the occurrence of postoperative cataracts. Currently, the commonly used capsule polishing methods are mainly achieved by mechanical friction between the polishing ring (ball) and the capsule, mechanical friction between the superemulsion injection needle or polishing needle and the capsule, or mechanical friction between the optical right-angle edge of the artificial lens and the posterior capsule. There are also methods of directly flushing the posterior capsule with water flow (only the posterior capsule can be polished). These capsule polishing methods have the following main disadvantages: the cortex remaining on the capsule surface cannot be discharged in time, thus reducing the polishing efficiency.

[0004] Therefore, an injection and suction capsule polisher for use in cataract surgery is proposed. Utility Model Content

[0019] See also Figure 1-4 The utility model provides a technical solution: an injection and suction capsule polisher used in cataract surgery, comprising a main body and an arc plate 1, such as Figure 1 As shown, the main body includes two symmetrically arranged rods 2, and the rods 2 are arranged in parallel. The two ends of the rods 2 are respectively fixedly connected as a whole by connecting members 3 to form an elliptical structure, so as to be easily sleeved on the periphery of the capsule membrane. The arc plate 1 corresponds to the rod 2, and the arc plate 1 is symmetrically arranged. The arc surface of the arc plate 1 is easy to fit with the capsule membrane, and the cleaning effect is very good. An adjustment mechanism is arranged between the arc plate 1 and the corresponding rod 2.
