Description

Technical Field

[0001] This utility model belongs to the field of experimental instrument technology, specifically relating to an eyeball holder. Background Art

[0002] Animal experiments are an essential part of biological and clinical medical research. In basic ophthalmological research, small mammals such as mice are widely used as experimental subjects. Therefore, it is often necessary to remove and store the eyeballs of experimental subjects to facilitate the separation and collection of tissues from the isolated eyeballs during experiments.

[0003] Currently, isolated eyeballs are often stored in test tubes and immersed in a solution to prevent them from deteriorating. However, this storage method has the following drawbacks:

[0004] When retrieving an eyeball, if a clamping instrument with a small contact area with the isolated eyeball is used, the isolated eyeball may be easily damaged. If a clamping instrument with a large contact area with the isolated eyeball is used, although damage to the isolated eyeball is avoided, the solution used to soak the isolated eyeball will enter between the isolated eyeball and the clamping instrument, hindering the operation of the clamping instrument and making it easy for the isolated eyeball to slip off the clamping instrument.

[0005] This invention addresses the aforementioned problems by providing an eyeball holder. Utility Model Content

[0031] Example 1

[0032] like Figure 1-2 An eyeball holder is shown, comprising a clamping assembly. The clamping assembly includes a first clamping arm 1 and a second clamping arm 2 arranged in a cross configuration. One end of the first clamping arm 1 is provided with a first clamping portion 11; one end of the second clamping arm 2 is provided with a second clamping portion 21. The first clamping portion 11 and the second clamping portion 21 are detachably connected. Both the first clamping portion 11 and the second clamping portion 21 are hemispherical structures with internal storage space. At least two through holes are provided on the sidewalls of both the first clamping portion 11 and the second clamping portion 21. Multiple through holes are regularly arrayed on the sidewalls of the first clamping portion 11 and the second clamping portion 21.

[0033] When the eyeball is removed, the first clamping part 11 and the second clamping part 21 have a large contact area with the isolated eyeball, which avoids damage to the isolated eyeball; as the clamping components tighten continuously, the liquid between the isolated eyeball and the clamping device gradually separates through the through hole, which prevents the solution soaking the isolated eyeball from hindering the operation of the clamping device and prevents the isolated eyeball from slipping off the clamping device.

[0034] In some embodiments of this application, the first clamping arm 1 includes a first power arm 12, a first rotating bracket, and a first resistance arm 13 arranged along an axis; the first rotating bracket is rotatably connected to the second clamping arm 2; the transmission of the first power arm 12 is less than the length of the first resistance arm 13. The first clamping part 11 is located at the end of the first resistance arm 13 away from the first power arm 12. The second clamping arm 2 includes a second power arm 22, a second rotating bracket, and a second resistance arm 23 arranged along an axis; the second rotating bracket is rotatably connected to the first clamping arm 1; the transmission of the second power arm 22 is less than the length of the second resistance arm 23. The second clamping part 21 is located at the end of the second resistance arm 23 away from the second power arm 22. The purpose of this design is:

[0035] 1. The transmission of the first power arm 12 is less than the length of the first resistance arm 13, and the transmission of the second power arm 22 is less than the length of the second resistance arm 23. The lever principle is applied to reduce the clamping force of the clamping assembly on the detached eyeball.

[0036] 2. The lengths of the first resistance arm 13 and the second resistance arm 23 have been extended, allowing the clamping assembly to extend into the storage container holding the detached eyeball, thus speeding up the retrieval of the eyeball and making it easier to use.

[0037] Furthermore, the first power arm 12 is provided with a first gripping end 121 at the end away from the first resistance arm 13, and the second power arm 22 is provided with a second gripping end 221 at the end away from the second resistance arm 23.

[0038] Specifically, both the first grip end 121 and the second grip end 221 are regular ring-shaped structures. When in use, different fingers are inserted into the first grip end 121 and the second grip end 221 respectively, which can achieve one-handed operation.

[0039] How to use this embodiment:

[0040] 1. Insert the first clamping part 11 and the second clamping part 21 into the container for storing the excised eyeball;

[0041] 2. Contact the first clamping part 11 or the second clamping part 21 with the isolated eyeball;

[0042] 3. Drive the isolated eyeball into the storage space of the first clamping part 11 or the second clamping part 21;

[0043] 4. Close the first gripping end 121 and the second gripping end 221 to drive the first clamping part 11 and the second clamping part 21 to close, and store the isolated eyeball in the storage space of the first clamping part 11 and the second clamping part 21.

[0044] 5. Drive the clamping assembly to detach the isolated eyeball from the container storing the isolated eyeball.

[0045] Example 2

[0046] like Figure 3-9 As shown, the difference between this embodiment and Embodiment 1 is that:

[0047] It also includes a limiting component 3; the limiting component 3 is slidably connected to the clamping component; one end of the limiting component 3 is inserted between the first clamping arm 1 and the second clamping arm 2. The purpose of the limiting component 3 is:

[0048] The gap between the first clamping arm 1 and the second clamping arm 2 is limited. When it is necessary to clamp the eyeball of an older rodent or a larger animal, the gap between the first clamping arm 1 and the second clamping arm 2 is increased to prevent the first clamping part 11 and the second clamping part 21 from excessively squeezing the detached eyeball, which would cause the detached eyeball to break.

[0049] Furthermore, the clamping assembly is provided with a slide rail 122; the limiting assembly 3 reciprocates linearly along the slide rail 122. The closer the limiting assembly 3 is to the clamping assembly, the larger the gap between the first clamping arm 1 and the second clamping arm 2 when they are closed; the farther the limiting assembly 3 is from the clamping assembly, the smaller the gap between the first clamping arm 1 and the second clamping arm 2 when they are closed. Based on this principle, the gap between the first clamping arm 1 and the second clamping arm 2 can be freely adjusted.

[0050] Specifically, slide 122 is located on the first power arm 12.

[0051] Alternatively, the slide 122 is located on the second power arm 22. This prevents the limiting component 3 from obstructing the insertion of the clamping component into the storage container holding the excised eyeball.

[0052] In the illustrative embodiment of this application, the limiting component 3 includes an adjusting arm 31, a sliding arm 32, and a buffer structure 33; one end of the sliding arm 32 is rotatably connected to the adjusting arm 31, and the other end is fixedly connected to the buffer structure 33; the sliding arm 32 is slidably connected to the clamping component.

[0053] In some examples of this application, one end of the sliding arm 32 is provided with a through hole; one end of the adjusting arm 31 is provided with a rotating shaft; the rotating shaft rotates inside the through hole.

[0054] Preferably, a working port 323 is provided on the side wall of the through hole; the rotating shaft can enter and exit the through hole through the working port 323, so that the limiting component 3 can be disassembled and removed from the clamping component.

[0055] In a specific example of this application, the sliding arm 32 includes a sliding structure 321 and an enlarged portion 322; a through hole is located at one end of the sliding structure 321; and the enlarged portion 322 is located at the end of the sliding structure 321 away from the through hole.

[0056] Preferably, the adjusting arm 31 includes a toggle section, a pressing section, and a rotating section; the pressing section is located between the toggle section and the rotating section; the rotating section is rotatably connected to the sliding arm 32; the pressing section is located on the side of the rotating section facing the buffer structure 33; and the toggle section is located on the side of the pressing section away from the buffer structure 33.

[0057] When the position of the limiting component 3 needs to be fixed, the adjusting arm 31 is rotated towards the enlarged portion 322, so that the pressing section and the enlarged portion 322 simultaneously press against both sides of the slide rail 122, using friction to limit the position of the limiting component 3. When the position of the limiting component 3 needs to be adjusted, the adjusting arm 31 is rotated away from the enlarged portion 322, so that the pressing section no longer abuts against the slide rail 122, allowing the limiting component 3 to move along the slide rail 122.

[0058] How to use this embodiment:

[0059] 1. Adjust the position of the limiting component 3 according to the size of the extracted eyeball to be retrieved;

[0060] 2. Rotate the adjusting arm 31 to fix the position of the limiting component 3;

[0061] 3. Insert the first clamping part 11 and the second clamping part 21 into the container for storing the excised eyeball;

[0062] 4. Contact the first clamping part 11 or the second clamping part 21 with the isolated eyeball;

[0063] 5. Drive the detached eyeball into the storage space of the first clamping part 11 or the second clamping part 21;

[0064] 6. Close the first gripping end 121 and the second gripping end 221 to drive the first clamping part 11 and the second clamping part 21 to close, clamping the isolated eyeball between the first clamping part 11 and the second clamping part 21;

[0065] 7. Drive the clamping assembly to detach the isolated eyeball from the container storing the isolated eyeball.
