Capsulectomy and capsulorhexis integrated device for cataract surgery

Abstract

The invention discloses a capsulectomy and capsulorhexis integrated device for a cataract surgery. The capsulectomy and capsulorhexis integrated device comprises an upper connecting middle rod and a lower connecting middle rod. Connecting holes are formed in the surfaces of the upper connecting middle rod and the lower connecting middle rod. A rotating transverse rod is arranged between the upperconnecting middle rod and the lower connecting middle rod. A through hole is formed in the surface of the rotating transverse rod. A connecting pin shaft penetrating through the through hole is inserted in the connecting holes. The outer side of the rotating transverse rod is connected with a fine capsulectomy device through a fine tuning capsulectomy structure. The inner sides of both the upper connecting middle rod and the lower connecting middle rod are connected with a hook-shaped gentle capsulorhexis device through an arced adjusting structure. The capsulectomy and capsulorhexis integrated device adopts integrated design, so that the capsulectomy device and the capsulorhexis device are combined together, and the cataract surgery can be conducted more smoothly; meanwhile, the capsulectomy and capsulorhexis integrated device changes the capsulorhexis mode of the capsulorhexis device, thus a capsulorhexis incision can be smoother and flatter, and the capsulorhexis quality is better;and in addition, the capsulectomy and capsulorhexis integrated device can further enable the capsulectomy and capsulorhexis processes to be more gentle, and thus the surgery effect is better.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to an integrated capsulotomy and hexis device for cataract surgery. Background technique [0002] All kinds of reasons, such as aging, heredity, local nutritional disorders, immune and metabolic abnormalities, trauma, poisoning, radiation, etc., can cause lens metabolic disorders, resulting in lens protein denaturation and turbidity, which is called cataract. Obstruction cannot be projected on the retina, resulting in blurred vision. It is more common in people over 40 years old, and the incidence rate increases with age. Cataracts can be divided into congenital and acquired. Congenital cataracts are also called developmental cataracts. Most of them exist before and after birth. Most of them are static. They can be accompanied by hereditary diseases. Acquired cataract is the opacity of the lens caused by systemic disease or local eye disease, abnormal nutrition metabolism, pois...

Problems solved by technology

[0006] (1) The existing capsulotomy and capsulorhexis devices used for cataract surgery are all used independently, so that when performing cataract surgery, it is necessary to replace the instrument many times, making the operation process more cumbersome, and it is easy to appear in a panic. Deviations that affect the operation;

[0007] (2) The existing capsulorhexis forceps used for cataract surgery are usually in the shape of tweezers. Although it can facilitate capsulorh
