Electric cutting device for rapidly cutting animal corneas

Abstract

The invention provides an electric cutting device for rapidly cutting animal corneas. The electric cutting device comprises a front eyeball fixing box arranged on a bottom fixing frame, and a lifting motor, wherein the lifting motor can be used for driving a back eyeball fixing box to move; the back eyeball fixing box is connected with a movable fixing frame; a sclerotome motor arranged on the movable fixing frame is used for driving a rotary sclerotome to cut an animal eyeball to form a circular sclerotome edge; a cutter barrel motor is used for driving a cornea cutting tool to move downwards along a sliding cavity, and is used for cutting a lower cornea by cooperating with a fixed cutter barrel on the outer ring of a cornea contact grid; when a bracket motor arranged on the bottom fixing frame is used for driving a movable suction bracket to move downwards, negative pressure is generated in a movable sealing ring to adsorb the cornea onto the air-permeable cornea contact grid; after the movable suction bracket is taken out and the cornea on the cornea contact grid is taken down, batch cutting can be performed repeatedly. The electric cutting device has the beneficial effects that the cutting device can be driven by the motor to rapidly cutting animal corneas, and standard corneas with regular edges can be obtained in batch for use in batch data scientific research and application.

Description

technical field [0001] The invention relates to an electric and 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 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 piercing ...

[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 piercing the sclera with scissors in the other hand and cutting the cornea along the edge of the cornea. Cutting is not easy to control, and the manual and fast animal corneal cutting device invented recently requires manual rotation of the scleral cutter and corneal cutter, etc. Each step requires meticulous care and certain technical difficulties. It is difficult to achieve perfect consistency and scientific standardization, and the speed is not fast, and the operation of cutting animal corneas in large quantities cannot be completed. To a certain extent, it affects the scientific experiment operation and easily pollutes the operator, especially when conducting large-scale scientific research experiments. The inconvenience is more prominent

It cannot meet the needs of current large-scale related scientific research and experiments, and hinders the in-depth development of related research. In order to overcome the above difficulties, it fundamentally solves the problem of convenient, fast, automatic, safe, accurate, Standard animal cornea cutting work to meet the needs of large-scale scientific experiments, the development of an electric fast animal cornea cutting device has become an inevitable and urgent research and development project
