Laser cornea cutting device for experimental animal

Abstract

The invention provides a laser cornea cutting device for an experimental animal. The laser cornea cutting device for the experimental animal comprises a lower bracket mounted on a bottom plate of a sealing cabin and an upper compressing cover, and eyeballs of the experimental animal can be compressed between the lower bracket and the upper compressing cover. Eyeball cornea penetrates through a circular hole in the middle of the upper compressing cover to be exposed out, and a hollow rotation tube driven by a driving motor penetrates through the top of the sealing cabin and can rotate freely. A laser generator is fixed on a movable link rod and can be adjusted up and down and front and back, so that it is guaranteed that a focus point of a laser beam can be placed on the outer circle of the cornea. The uppermost portion of the hollow rotation tube is connected to the inside of an atomization cavity, the lower edge of the hollow rotation tube is connected with a mist diffusion opening, atomized normal saline can be transmitted, the laser beam emitted by the laser generator which rotates at a constant speed makes circular motion on the focus point along the outer edge of the cornea, neat and clean cutting is achieved, and the standard cornea with good consistency is obtained. The laser cornea cutting device for the experimental animal has the advantages that blade cutting is avoided, and the problem for conducting mass standard animal cornea cutting work conveniently, rapidly, automatically, safely and accurately is solved.

Description

technical field [0001] The invention relates to a laser cornea cutting device for experimental animals. Background technique [0002] In the development of modern toxicology, the identification and scientific research of chemicals for ocular irritation often require corresponding toxicological experiments. In the past, most experiments were carried out with live animals, but now less and less live animal experiments are used, and even more The emphasis is on the use of substitutes and isolated animal organs such as corneas of corneas, corneas of rabbits, corneas of pigs, corneas of cows, etc. It involves the development of artificial corneas, human eye disease treatment and analysis, human corneal transplantation, and animal ophthalmology research in veterinary medicine. A large number of animal corneas need to be used in scientific research, experiments and teaching. In the past, cutting the animal cornea was simply done by holding the animal's eyeball in one hand and pier...
