Description

corneal scissors for ophthalmology

technical field

The present application relates to the technical field of corneal scissors, and more particularly, to corneal scissors for ophthalmology.

Background technique

The cornea is the transparent part of the front of the outer layer of the eyeball wall. The front is slightly protruding, curved like a spherical surface, and has the effect of refraction. The cornea is rich in sensory nerve endings, and any slight irritation, injury or inflammation can cause pain and tearing. If the cornea is touched lightly with cotton, a protective response to the closure of the eye cleft, called the corneal reflex, is evoked.

When corneal lesions occur, it is necessary to perform surgery on the cornea. Generally, corneal scissors are used to cut the cornea. Most of the existing corneal scissors are one-piece structures. Because there are many types of corneal scissors, different diseases require different Corneal scissors, the one-piece structure can only replace the entire corneal scissors, which increases the production cost of the corneal scissors. At the same time, because the eyes are relatively sensitive and fragile, if the corneal scissors are contaminated, it will cause damage to the eyes. Corneal scissors lack protective devices, so we propose ophthalmic corneal scissors.

Utility model content

In view of the above problems, the present application proposes corneal scissors for ophthalmology to improve the above problems.

In order to achieve the above purpose, the present utility model is achieved through the following technical solutions: corneal scissors for ophthalmology, including a scissors head, the right side of the scissors head is provided with a clip slot, the right side of the scissors head is provided with a first scissors handle and a scissors head. The second scissors handle, the left ends of the first scissors handle and the second scissors handle are fixedly connected with threaded rods, the threaded rods are matched with the clamping grooves, and a protective cover is provided on the outside of the scissors head.

Optionally, a first spring piece is fixedly connected to the right side of the first scissors handle, a snap ring is fixedly connected to the right side of the first spring piece, and a square hole is opened in the inside of the snap ring.

Optionally, a second spring piece is fixedly connected to the right side of the second scissors handle, and a clamping block is fixedly connected to the right side of the second spring piece, the shape of the clamping block is a rectangle, and the clamping block is long. The length of the side is equal to the length of the diagonal of the inner square hole of the snap ring, and the snap block is matched with the snap ring.

Optionally, the first scissors handle and the second scissors handle are respectively connected together by threaded rods with the grooves inside the scissors head, and the structures of the first scissors handle and the second scissor handle are similar.

Optionally, a fixing pad is provided inside the protective cover, and a limiting groove is defined in the interior of the fixing pad, and the limiting groove is adapted to the scissors head.
