Description

Technical Field

[0001] The invention relates to the technical field of experimental equipment, and in particular to a simple fixing device that can be reused. Background Art

[0002] Laboratory mice are the most important experimental animals for basic and clinical research in medical fields. In most cases, the laboratory animals must be fixed to reduce their activities and facilitate the smooth progress of the experimental process. In addition, oral medicine experiments (part of other medical experiments) often involve the auxiliary opening of the oral cavity of the laboratory animals, so as to conduct experiments on teeth, mucosa and bone tissue inside the oral cavity. During the laboratory mouse experiment, due to its small size, it is not easy to tie it up or the binding operation is complicated and time-consuming, resulting in low experimental efficiency and easy escape. A small number of auxiliary laboratory mouse opening devices cannot fix its upper jaw. Although the laboratory mouse's mouth can be opened, there is a possibility that the upper jaw and head of the laboratory mouse will move left and right, which is not conducive to stability during operation. At the same time, a considerable part of the operation content inside the laboratory mouse's mouth (such as pulp opening of teeth, etc.) must be completed under a stereo microscope, which requires the stability of the head when the auxiliary laboratory mouse's mouth is opened, so as to keep the adjusted depth of field and magnification of the stereo microscope unchanged, which is conducive to the efficient conduct of the experimental process, thereby reducing the operation time, and is conducive to the laboratory animal suffering the least trauma, and having the fastest recovery speed.

[0003] The existing mouse fixing devices are usually effective in fixing the body of the experimental mouse, including internal and external tube fixing, Velcro clothing fixing, binding cloth and adhesive tape fixing and other methods. Binding cloth and adhesive tape fixing also include a fixing plate, which is to set the binding cloth with bonding positions corresponding to the abdomen and neck of the experimental mouse, and at the same time set openings at the head, back, abdomen and limbs of the experimental mouse to facilitate the exposure of the corresponding parts and conduct experimental operations. The adhesive tape is set on the bonding position for bonding and fixing the experimental mouse. In terms of assisting the opening of the experimental mouse, there is an invention that uses an orthodontic steel wire to bend the corresponding shape of the mouth opener, which is placed in the oral cavity of the experimental mouse to open it, but it cannot stabilize the head of the experimental mouse.

[0004] As mentioned above, the existing fixation devices for experimental mice include multiple methods such as inner and outer tube fixation, Velcro fixation, binding cloth and adhesive tape fixation; however, they are all designed for the purpose of fixing or grabbing experimental mice simply and conveniently, but still have the disadvantage of complicated operation, and none of them are designed for fixing the heads of experimental mice and facilitating operation under stereo microscopes. The inner and outer tube fixation is convenient for the operator to hold the device by hand for simple operation, but it is not very helpful for the operation of the oral cavity of the experimental mouse head and the sampling; although the binding and adhesive tape and Velcro clothes can fix the experimental mouse on the bracket more conveniently, they are still relatively complicated and costly; at the same time, they cannot achieve effective fixation of the head of the experimental mouse.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The purpose of the present invention is to provide a reusable simple fixing device to solve the problems existing in the above-mentioned prior art, realize auxiliary opening of the experimental mouse, and effectively fix the head of the experimental mouse.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 8 As shown: This embodiment provides a reusable simple fixing device 100, including an operating plate 1, a thread 8, two building block forward blocks 3 and four leg fixers 13.

[0031] Among them, a groove is arranged in the middle of the operation panel 1, and a supporting block 2 is arranged in the groove. The size of the supporting block 2 matches the size of the groove. The supporting block 2 is detachably connected to the groove, and the material of the supporting block is foam plastic or sponge. When fixing the body of the experimental mouse, the supporting block 2 serves as a buffer between the experimental mouse and the operation panel 1, which can facilitate the fixing of the body of the experimental mouse, and the supporting block 2 has low cost and is easy to replace.

[0032] The leg fixer 13 is in the shape of a double-tine fork, and the leg fixer 13 can be inserted into the operating panel 1; the operating panel 1 is made of hard plastic, and the leg fixer 13 is made of metal or hard plastic; one leg fixer 13 is used to fix one leg of the experimental mouse. Specifically, first fix the leg of the experimental mouse, and then insert the leg fixer 13 into the supporting block 2, and make the leg of the experimental mouse located between the two tines of the leg fixer 13, so that the leg of the experimental mouse is stuck between the leg fixer 13 and the operating panel 1, and then repeat the same operation to fix the other three legs of the experimental mouse.

[0033] Two vertical winding posts 5 are fixedly arranged at one end of the operation panel 1, and a clip 7, a horizontal rod 9 and two horizontal winding posts 6 are fixedly arranged on the side wall of the operation panel 1 near the two vertical winding posts 5. A hollow portion is arranged on the side wall of the operation panel 1 corresponding to the horizontal rod 9, and the horizontal rod 9 is fixedly arranged in the hollow portion; the clip 7 is clamped on the horizontal rod 9, the horizontal rod 9 is parallel to the side wall, the horizontal winding post 6 is perpendicular to the side wall, one end of the wire 8 is fixedly connected to one horizontal winding post 6, and the other end is fixedly connected to the clip 7, and the wire 8 is wound around the two vertical winding posts 5 and the other horizontal winding post 6. Screws can be used as the vertical winding posts 5 and the horizontal winding posts 6.

[0034] After the body of the experimental mouse is fixed, the front teeth of the experimental mouse are pulled with silk thread 8 and the tightness of the silk thread 8 is adjusted to a suitable level by adjusting the position of the clamp 7 clamped on the horizontal rod 9. Under the action of the silk thread 8, the experimental mouse is kept in an open state and the head of the experimental mouse is stabilized.

[0035] The operation panel 1 is provided with two vertical winding posts 5, and one end of the two vertical winding posts 5 is also provided with two lifting screws 4, which pass through the operation panel 1 and are threadedly connected to the operation panel 1. Under the action of the lifting screws 4, when the operation panel 1 is placed, the operation panel 1 can be kept in an inclined state, which is convenient for the experimenter to observe the experimental mouse under the stereo microscope, and the tilt angle of the operation panel 1 can be adjusted by adjusting the lifting screws 4, which is convenient to use.

[0036] The building block forward block 3 includes a block-shaped body 12 and a plug-in block 11 arranged at one end of the block body 12. A recessed portion 10 is arranged on the side wall of the operating panel 1 away from the horizontal rod 9 and on one end of the block body 12 away from the plug-in block 11 corresponding to the plug-in block 11. The size of the plug-in block 11 matches the size of the recessed portion 10. The building block forward block 3 is connected to the operating panel 1 by inserting the plug-in block 11 into the recessed portion 10 on the operating panel 1. The connection between different building block forward blocks 3 is achieved by inserting the plug-in block 11 into the recessed portion 10 in another building block forward block 3. The main function of the building block forward block 3 is to facilitate the adjustment of the position of the operating panel 1. When observing the experimental mouse under a stereo microscope, the position of the experimental mouse needs to be adjusted. However, when adjusting the position of the experimental mouse, if the position of the operating panel 1 is only adjusted manually, the error of the operation will be very large. When using the building block forward block 3, the building block forward block 3 is inserted into the recessed portion 10 of the operating panel 1, and then the building block forward block 3 is placed against the edge of the workbench. In this way, the adjustment distance is fixed each time, avoiding the error that may be caused by directly manually adjusting the operating panel 1; the specific setting number of the building block forward block 3 can be adaptively adjusted according to actual needs.
