Fast animal cornea cutting device

Abstract

The invention provides a fast animal cornea cutting device which comprises a front eyeball fixing box and a rear eyeball fixing box, wherein the front eyeball fixing box and the rear eyeball fixing box are tightly buckled together to fix an animal eyeball; eyeball fixing needles are arranged on the two boxes; a rotary sclera knife is arranged on the rear eyeball fixing box to cut a sclera open and enable a cornea cutting knife to penetrate through the cut sclera, move downwards along a sliding cavity running through the middle parts of the boxes, and interact with a fixed knife cylinder on the outer ring of a cornea contact grid to cut down the cornea; when a movable suction bracket is drawn outwards, a displaceable seal ring is stretched to expand the volume of the interior of a negative-pressure fixed cavity so as to generate negative pressure and enable the cornea to be attached to the ventilated cornea contact grid and to be taken out; after the movable suction bracket is drawn out, the shape of the displaceable seal ring is recovered and the negative pressure disappears, the cornea on the cornea contact grid can be taken down easily, and the subsequent scientific research and application can be performed. The invention has the benefit that the fast animal cornea cutting device can perform manual operation of cutting an animal eyeball conveniently and fast so as to obtain a standardized cornea with a neat edge for scientific research and application.

Description

technical field [0001] The invention relates to a fast animal cornea cutting device. 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 alternative and isolated animal organs such as corneas of corneas, corneas of rabbits, corneas of pigs, corneas of bovines, etc. for corrosion, turbidity, permeability, etc. Scientific research involves the development and development of artificial corneas, human eye disease treatment and analysis, human corneal transplantation, and animal ophthalmology research in veterinary medicine.

[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 alternative and isolated animal organs such as corneas of corneas, corneas of rabbits, corneas of pigs, corneas of bovines, etc. for corrosion, turbidity, permeability, etc. Scientific research involves the development and development of artificial corneas, human eye disease treatment and analysis, human corneal transplantation, and animal ophthalmology research in veterinary medicine. A large number of fields need to use animal corneas for scientific research experiments, and a large number of animal eyes are also required in the teaching process. Cornea is done. In the past, animal cornea was cut simply by holding the animal’s eyeball in one hand and piercing the sclera with scissors in the other hand and cutting the cornea along the edge of the cornea. Corneal shearing is not easy to control, etc., which makes it difficult to achieve perfect and consistent scientific standardization, which affects the scientific experiment operation to a certain extent and is easy to scratch the operator, especially the inconvenience caused by large-scale scientific research experiments is more prominent. It cannot adapt to the current relevant scientific research and experimental needs, and hinders the in-depth development of related research. In order to overcome the above difficulties, it fundamentally solves the problem of convenient, fast, safe, accurate and standard cutting of a large number of animal corneas in scientific research and experiments. To meet the needs of scientific experiment conditions, the research and development of a fast animal corneal cutting device has become an inevitable and urgent research and development project
