Description

Anterior chamber intraocular pressure maintaining device for ophthalmologic operation

Technical Field

The utility model relates to the technical field of ophthalmic surgery, in particular to an anterior chamber intraocular pressure maintaining device for ophthalmic surgery.

Background

The cavity between the back of the cornea and the iris and lens is called the anterior chamber, which is filled with colorless liquid, i.e., aqueous humor. All anterior segment operations in the operation process are operated in the anterior chamber, the depth seriously affects the operation space of an operator, instruments touch an corneal endothelial cell layer in the over-shallow operation process to cause corneal endothelial cell loss, and the corneal endothelial cell layer is formed by a layer of hexagonal endothelial cells.

The endothelial cell layer is formed by the mosaic of a single layer of hexagonal flat cells, the cells cannot regenerate from birth to death, and the positions left by aged and dead cells are paved by the enlarged migration of other endothelial cells. Damage is also covered by the enlargement, expansion and sliding of adjacent endothelial cells. The endothelial cell layer continuously drains water molecules from the stromal layer into the anterior chamber, leaving the stroma in a dehydrated state and remaining clear, thus functioning properly, depending on whether the entire cornea is clear. Anterior chamber depth is particularly important in anterior segment surgery. The existing device for maintaining the intraocular pressure in the anterior chamber during the operation discovers that the original device is cylindrical, damages corneal tissue in the implantation process, causes the incision to be circular, has poor tightness during watertight incision, causes incision leakage, causes a series of complications such as intraocular infection and the like, and cannot achieve the purpose of safety and convenience.
