Problems solved by technology

[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 han

Embodiment

[0017]When in use, first prepare the fresh isolated animal eyeball 21 for the experiment, and select the animal cornea 17 cutting device of the corresponding size according to the type of animal to be used, and carry out disinfection and disassembly work in advance, first put the movable suction tray Push the frame 14 into the round hole of the sliding chamber 16 at the bottom of the anterior eyeball fixing box 10, let the displaceable sealing ring 15 stick to the sliding chamber 16 and seal it well, and put the selected isolated animal eyeball 21 downward into the anterior eyeball for fixation In the garden groove of the box 10, let the cornea 17 of the animal eye just stick to the cornea contact grid 13, and ensure that the fixed knife barrel 11 on the cornea contact grid 13 is aligned with the cornea cutting line at the junction of the cornea 17 and the sclera 19 of the animal eye On the 18 circle, set the rear eyeball fixing box 7 on the top of the front eyeball fixing box ...

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.
