Abstract

The invention relates to the technical field of medical instruments and discloses a special nucleus chopping device for cataract surgery. The nucleus chopping device comprises a nucleus chopping device handle, a nucleus chopping device connecting rod and a nucleus chopping knife, wherein the nucleus chopping device handle is connected with the nucleus chopping device connecting rod; a U-shaped connecting port is formed in the end, close to the nucleus chopping knife, of the nucleus chopping device connecting rod; and the end, close to the nucleus chopping device connecting rod, of the nucleuschopping knife is inserted into the U-shaped connecting port and rotationally connected with the nucleus chopping device connecting rod through a pivot. According to the nucleus chopping device, the nucleus chopping device connecting rod is rotationally connected with the nucleus chopping knife, the included angle between the nucleus chopping device connecting rod and the nucleus chopping knife can be adjusted according to the size of an eye nucleus during an operation so as to complete clamping of the eye nucleus, and practicability is higher.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a special nuclear chopper for cataract surgery. Background technique [0002] Cataract is a relatively common ophthalmic disease, especially in the elderly population, which greatly affects the visual sense and daily life. In recent years, the incidence of cataract tends to be younger, and even serious blindness. Most cataracts can be alleviated or treated by surgery, and the commonly used surgical instrument is a nuclear chopper. [0003] Existing splitter, such as patent CN208065335U, "a kind of splitter for cataract", its splitter connecting rod and splitter all adopt an integrally formed structure, and the connection angle between the two is certain, which cannot be adjusted and adapted. Nuclei of different sizes. For this reason, how to solve the above technical problems has become the focus of research by those skilled in the art. Contents of the invention ...
