Reverse chopping hook for cataract surgery

Abstract

The invention provides a reverse chopping hook for a cataract surgery. The reverse chopping hook for the cataract surgery is made of a titanium alloy material and comprises a hook handle and a hook body, wherein the hook body is integrally connected with the hook handle; a plurality of longitudinal anti-sliding ridges are distributed on the surface of the hook handle along the axial direction; the rear section of the hook body extends along the axial direction of the hook handle; the whole front section of the hook body is bent upwards; an end of the front end of the hook body is bent downwards and an arc-shaped hook is formed by inward bending; the curvature of the arc-shaped hook is progressively increased along with extension of the arc-shaped hook; two ends of the arc-shaped hook have finely rounded structures; the straight-line distance between two ends of the arc-shaped hook is 2.2-2.6mm; and a blade is arranged on the inner side of an arc-shaped elbow of the arc-shaped hook. The reverse chopping hook for the cataract surgery is reasonable in structure and safe and convenient to operate, grabs a nucleus firmly, chops the nucleus thoroughly, and has high chopping efficiency. The titanium alloy material has the advantages of high strength, high corrosion resistance, high heat resistance and the like; the chopping hook can be reused after being sterilized thoroughly; and reasonable allocation of resources is guaranteed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a trans-chopping hook for cataract surgery. Background technique [0002] Cataract refers to the turbidity of the lens in the eyeball, which changes from transparent to opaque, preventing light from entering the eye, thereby affecting vision. In the early stage, the turbidity is slight or small and does not affect vision, and then gradually aggravates to significantly affect vision or even blindness. At present, with the development of society, the aging of the population is becoming more and more serious, and the incidence of senile cataract is also increasing. The vision loss caused by cataract cannot be corrected by wearing glasses, and it is difficult to achieve effective therapeutic effects with drug treatment. Only surgery can be the solution. The only effective method for cataracts. Now the most commonly used surgical method is phacoemulsification, which is very simple to o...

Problems solved by technology

[0005] (1) During the operation, it is necessary to extend the splitting hook from the edge of the annular capsulorhexis to the equator of the lens. Since the hook head of the splitting hook in the prior art is a semicircular structure, it is not easy to extend the hook head during the operation. , resulting in prolongation of operation time and increased suffering of patients;

[0006] (2) The capsulorhexis required during the operation is relatively large, and it is difficult to operate in the case of small pupils;

[0007] (3) Because some operations are performed under non-direct vision conditions, for doctors with little surgical experience, the disadvantages of intraoperative complications often occur
