Description

Technical Field

[0001] The utility model belongs to the technical field of experimental equipment, and particularly relates to a device for observing an experimental region of interest in a reverse direction. Background Art

[0002] As is well known, animal experiments play a crucial role in the medical cause of human beings. Through in-depth research on animal experiments, scientific research workers can more comprehensively understand the basic information of animals, and at the same time can also exercise the surgical operation skills of scientific research workers. During some surgical experiments, scientific research workers need to simultaneously perform relevant intervention operations (such as cerebral ischemia process, intestinal ischemia process, etc.) and observe the changes in the experimental region of interest (such as the brain, spinal cord, mesenteric blood vessels, and back skin, etc.), which is a complex and challenging task. For forward observation instruments, such as blood flow imagers, etc., during relevant intervention experimental operations, the changes in the experimental region of interest cannot be observed, which brings certain troubles to scientific research workers. Therefore, designing and developing a device that can conveniently observe the changes in the experimental region of interest has extremely important scientific significance. Content of the Utility Model

[0003] Aiming at the problems existing in the prior art, the utility model provides a device for observing an experimental region of interest in a reverse direction, which uses two isosceles right triangular prisms with the same structure and size to be spliced into a large isosceles right triangular prism, thereby realizing 180-degree mirror imaging of the optical path.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A device for observing an experimental region of interest in a reverse direction includes an experimental table; on the upper surface of the experimental table, there are provided an independent first optical lens group and a second optical lens group; both the first optical lens group and the second optical lens group are in the structure of an isosceles right triangular prism; wherein:

[0006] The first optical lens group is composed of a first mirror conduction prism and a second mirror conduction prism; the second optical lens group is composed of a third mirror conduction prism and a fourth mirror conduction prism;

[0007] The first mirror conduction prism and the second mirror conduction prism are isosceles right triangular prisms with the same structure and size; a rectangular side surface of the first mirror conduction prism and a square side surface of the second mirror conduction prism are mutually attached; the other rectangular side surface of the first mirror conduction prism and the other rectangular side surface of the second mirror conduction prism are spliced into a first optical surface; the first optical surface is located at the top of the first optical lens group and is parallel to the upper surface of the experimental table;

[0008] The third mirror conduction prism and the fourth mirror conduction prism are isosceles right triangular prisms with the same structure and size; one rectangular side of the third mirror conduction prism is in contact with one rectangular side of the fourth mirror conduction prism; the other rectangular side of the third mirror conduction prism and the other rectangular side of the fourth mirror conduction prism are spliced to form the second optical surface; the second optical surface is located at the top of the second optical lens group and is parallel to the upper surface of the experimental table.

[0009] Preferably, two V-shaped slots are provided on the upper surface of the experimental table, and the first optical lens group and the second optical lens group are located in the V-shaped slots.

[0010] Preferably, the first optical lens group is formed by bonding the joint surfaces of the first mirror conduction prism and the second mirror conduction prism with optical glue.

[0011] Preferably, the first optical lens group is connected by a tape on the side walls of the first mirror conduction prism and the second mirror conduction prism.

[0012] Preferably, the second optical lens group is formed by bonding the joint surfaces of the third mirror conduction prism and the fourth mirror conduction prism with optical glue.

[0014] Preferably, a reflective film is plated on the triangular sides of the first optical lens group and the second optical lens group.

[0015] Compared with the prior art, the advantages and positive effects of this application are:

[0016] This utility model ingeniously adopts two isosceles right triangular prisms with exactly the same structure and size. Through precise splicing, a larger isosceles right triangular prism, that is, an optical lens group, is formed. With this unique structural design, a 180-degree mirror imaging effect of the optical path is achieved. This innovative design provides a very convenient optical tool for scientific researchers, making it more intuitive and clear when they observe the experimental interest area.

[0017] In order to ensure the stability and accuracy during the experiment, this utility model ingeniously sets two V-shaped slots on the upper surface of the experimental table. The main function of these two V-shaped slots is to stably clamp the optical lens group and prevent accidental position slippage during the experiment, thus ensuring the smooth progress of the experiment.

[0018] In addition, a highly efficient reflective film is coated on the triangular side surface of the optical lens group of the present utility model. This design not only improves the optical performance of the optical lens group, but also can reduce optical noise to a certain extent, enhancing the stability and clarity of the optical path. In this way, when scientific researchers conduct experimental observations, they can obtain more accurate and clear optical images, thereby improving the credibility of experimental results.

[0019] In summary, by ingeniously designing the splicing structure of two isosceles right triangular prisms, the present utility model realizes 180-degree mirror imaging of the optical path, providing a convenient optical observation tool for scientific researchers. At the same time, by setting the V-shaped card slot and the reflective film, the stability of the experimental process and the clarity of the optical image are ensured, greatly improving the experimental efficiency and the accuracy of the results.
