A size-adjustable fixation device for isolated eyeball

Abstract

The invention provides an in-vitro eyeball fixing device with an adjustable size. The in-vitro eyeball fixing device comprises an eyeball stand, wherein the eyeball stand is fixedly arranged on lifting frame legs and is provided with a universal lift handle; a middle inner hole is formed in the center of the eyeball stand; a plurality of movable support rods are arranged at the edge of the eyeball stand; one end of each movable support rod is connected with the eyeball stand through a centering small shaft; a movable rotary ring is arranged between the movable support rods and the eyeball stand, and is supported by constrained bearings, and is provided with an adjusting handle and slide shift shafts; each slide shift shaft penetrates through a strip slide groove in the middle section of the corresponding movable support rod and drives the corresponding movable support rod to synchronously move along the same direction; the sliding of each movable support rod can be prevented by antiskid inner teeth and a handle spring on the adjusting handle; a flexible protecting support is arranged at the top end of each movable support rod, and is used for fixing in-vitro eyeballs adaptive to different diameters due to the distance change of the movable support rods without injuries. The in-vitro eyeball fixing device has the beneficial effects that the size can be adjusted, and the in-vitro eyeballs with different diameters can be fixed; the subsequent experiment, testing, dissection and other medical scientific and research work of human and animal in-vitro eyeballs can be conveniently and rapidly performed.

Description

technical field [0001] The invention relates to an adjustable-size isolated eyeball fixation device. Background technique [0002] During the development of modern toxicology, corresponding toxicological experiments are often required in the identification and scientific research of chemicals for eye irritation. In the past, most experiments were carried out with live animals, but now less and less live animal experiments are used, and more attention is paid to The most important thing is to use alternatives and use isolated animal organs such as rabbit eyeballs, pig eyeballs, bull eyeballs, etc. to conduct experiments on corrosion, turbidity, permeability, etc., and in general medical clinical research involves the development of artificial corneas. Research, human eye disease treatment and analysis, human corneal transplantation, and veterinary animal ophthalmology scientific research require the use of isolated animal eyeballs for scientific research, experiments and teac...

[0002] During the development of modern toxicology, corresponding toxicological experiments are often required in the identification and scientific research of chemicals for eye irritation. In the past, most experiments were carried out with live animals, but now less and less live animal experiments are used, and more attention is paid to The most important thing is to use alternatives and use isolated animal organs such as rabbit eyeballs, pig eyeballs, bull eyeballs, etc. to conduct experiments on corrosion, turbidity, permeability, etc., and in general medical clinical research involves the development of artificial corneas. Research, human eye disease treatment and analysis, human corneal transplantation, and veterinary animal ophthalmology scientific research require the use of isolated animal eyeballs for scientific research, experiments and teaching. In the past, animal eyeballs could only be fixed in a single size. That is to say, one fixation device can only fix the isolated eyeballs of one kind of diameter. If you need to use different kinds of animal eyeballs, you need multiple fixation devices. Some isolated eyeballs cannot be fixed because the diameter is too large or too small. Therefore, the research scope of the experiment is restricted, the quality and safety of scientific experiment operations are affected to a certain extent, and the in-depth development of related research is hindered. Eyeball, convenient and quick to carry out medical scientific research work such as experiments, tests, and dissections of human and animal isolated eyeballs
