Laser cornea cutting device for experimental animal

Abstract

The invention provides a laser eye cornea cutting device for experimental animals, which includes a lower bracket and an upper compression cover installed on the bottom of the sealed cabin, and the eyeball of the experimental animal can be compressed between them, and the cornea of ​​the eyeball can pass through the upper compression cover The round hole in the middle is exposed, and the hollow rotary tube driven by the drive motor can rotate freely through the top of the sealed cabin. The laser generator is fixed on the movable link and can be adjusted up and down to ensure that the focus of the laser beam is on the outer circle of the cornea. The uppermost part of the hollow rotating tube is connected to the atomization chamber, and the lower part is connected to the mist diffusion port, which can transmit the atomized saline solution. The laser beam emitted by the uniformly rotating laser generator moves neatly and cleanly along the outer edge of the cornea at the focal point. The cutting can obtain consistent and standardized cornea. The beneficial effect of the present invention is: a kind of laser cornea cutting device without blade cutting has been developed, which can solve the large-scale, convenient, fast, automatic, safe, accurate and standard Problems with cutting corneas in animals.

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...
