Description

A finger-sleeve scleral depressor

technical field

The utility model particularly relates to the technical field of ophthalmic surgical instruments, in particular to a finger-sleeve type scleral depressor.

Background technique

The eyeball is a ball full of contents; the eyeball is composed of two parts, the eyeball wall and the eyeball contents; the eyeball wall has three layers, the outermost layer is called the fibrous membrane, which is very strong. It consists of two parts, the cornea and the sclera; the transparent front is called the cornea, and the back is the sclera. The second bulbous wall of the eyeball is the pigmented membrane, also called the uvea, which is rich in blood vessels and pigment. The innermost layer of the eyeball is the retina, which is a transparent film that acts like the film in a camera.

A scleral depressor is required when it is necessary to treat peripheral retinal lesions or to excise the vitreous near the serrata. Because the main surgeon needs to hold the light guide light source in one hand and the vitrectomy head or other operating instruments in the other hand, the scleral depressor needs to be operated by an assistant. When the assistant is inexperienced, it is easy to affect the operation efficiency of the main surgeon, and in severe cases, it may even cause the main surgeon to cut the retina by mistake, causing damage to the patient.
