DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 -Attached Figure 7 , further details of this application are given. Example

[0030] A tool for conducting animal experiments using a fiber optic probe, referring to Figure 1The apparatus comprises a stage 1, a Z-axis translation mechanism 2, and a clamp 3. The Z-axis translation mechanism 2 is mounted on the stage 1, and the clamp 3 is mounted on the Z-axis translation mechanism 2. The Z-axis translation mechanism 2 is used to drive the clamp 3 to move along the Z-axis. During animal experiments, an animal sample is placed on the stage 1, and the fiber optic probe is clamped and secured using the clamp 3. The Z-axis translation mechanism 2 drives the clamp 3 to move, thereby moving the fiber optic probe toward or away from the animal sample. In this embodiment, to increase the stability of the fiber optic probe, the clamp 3 simultaneously clamps the fiber optic probe and the optical fiber.

[0031] Reference Figure 2 and Figure 3 The clamp 3 includes a first pressure plate 31, a second pressure plate 32, and an elastic member 33. The first pressure plate 31 is fixed to the Z-axis translation mechanism 2, and the second pressure plate 32 is rotatably connected to the first pressure plate 31. The elastic member 33 is disposed between the first and second pressure plates 31, 32, with one end acting on the first pressure plate 31 and the other end acting on the second pressure plate 32. The rotation of the second pressure plate 32 increases the space between the first and second pressure plates 31, 32. At this time, the optical fiber probe is placed between the first and second pressure plates 31, 32. The second pressure plate 32 is released, and the second pressure plate 32 is driven back to its original position by the elastic member 33, so that the first and second pressure plates 31, 32 clamp the optical fiber probe, thereby fixing the optical fiber probe.

[0032] Specifically, the first pressure plate 31 defines a telescopic slot 311. A portion of the elastic member 33 is disposed within the telescopic slot 311, while the remaining portion extends out of the slot 311 and acts on the second pressure plate 32. In this embodiment, the elastic member 33 is configured as a spring; in other embodiments, it may be a rubber pad or other elastic component. In this embodiment, one end of the elastic member 33 abuts the inner wall of the telescopic slot 311, and the other end abuts the second pressure plate 32. In other embodiments, one end of the elastic member 33 abuts the inner wall of the telescopic slot 311, and the other end is fixedly connected to the second pressure plate 32.

[0033] Specifically, the second pressure plate 32 includes a rotating portion 321, a pressing portion 322, and an abutting portion 323. The pressing portion 322 is fixedly connected to one end of the abutting portion 323 and is used to compress the optical fiber probe. The rotating portion 321 is fixedly connected to the abutting portion 323. The rotating portion 321 can be integrally formed with the pressing portion 322 or spaced apart from the pressing portion 322. The first pressure plate 31 has a notch 313, into which the rotating portion 321 is inserted. The clamp 3 also includes a rotating shaft 35, which is disposed within the notch 313 and inserted into the rotating portion 321. The rotating portion 321 rotates about the rotating shaft 35, thereby achieving a rotational connection between the second pressure plate 32 and the first pressure plate 31.

[0034] In this embodiment, a single rotating shaft 35 is provided and fixedly connected within the notch 313, and the rotating portion 321 is rotatably mounted on the rotating shaft 35. In other embodiments, two rotating shafts 35 may be provided, with one rotating shaft 35 passing through the first pressing plate 31 from the top surface and inserted into the notch 313, and the other rotating shaft 35 passing through the first pressing plate 31 from the bottom surface and inserted into the notch 313. The two rotating shafts 35 abut against each other and are coaxially arranged, and the rotating portion 321 is simultaneously rotatably mounted on the two rotating shafts 35. Compared to providing a single rotating shaft 35, providing two rotating shafts 35 does not require a longer length of the rotating shaft 35, occupies less space during installation, and is more convenient for installing the rotating shaft 35.

[0035] In other embodiments, the rotating portion 321 may be fixedly connected to the rotating shaft 35 , and the rotating shaft 35 may be rotatably connected to the inner wall of the notch 313 , as long as the rotating portion 321 can be rotatably connected to the first pressing plate 31 .

[0036] Furthermore, a limiting groove 312 is provided on the first pressure plate 31 and / or the second pressure plate 32. In this embodiment, the limiting groove 312 on the first pressure plate 31 is taken as an example for introduction. The limiting groove 312 is arranged to pass through the first pressure plate 31 along the Z-axis direction. The limiting groove 312 is adapted to the optical fiber probe. The movement of the optical fiber probe is limited by the limiting groove 312, and the optical fiber probe is then pressed by the pressing portion 322, thereby fixing the optical fiber probe.

[0037] Furthermore, a plurality of limiting grooves 312 are provided, and the limiting grooves 312 are of different sizes for adapting to optical fiber probes of different sizes. The shape of the limiting groove 312 is preferably a V-shaped groove in this embodiment, and in other embodiments, a semicircular or other shape can be selected as long as it meets the experimental requirements.

[0038] Furthermore, a tool for conducting animal experiments using a fiber optic probe also includes a clamp support rod 34, one end of which is fixedly connected to the Z-axis translation mechanism 2, and the other end of the clamp support rod 34 is fixedly connected to the first pressure plate 31. In this embodiment, the first pressure plate 31 and the clamp support rod 34 are detachably connected. The specific detachable connection method can be a detachable connection using bolts or a detachable connection using a snap fastener, which facilitates the replacement of the clamp 3.

[0039] The Z-axis translation mechanism 2 includes a guide rod 21, a slider 22 and a locking piece 23. The guide rod 21 is fixedly arranged on the worktable 1 along the Z-axis direction. The slider 22 is slidably connected to the guide rod 21. The locking piece 23 is arranged on the slider 22 and can be pressed against the guide rod 21 to limit the sliding of the slider 22. The clamp support rod 34 is fixedly connected to the slider 22 to achieve mutual fixation between the clamp 3 and the slider 22. The sliding of the slider 22 drives the clamp support rod 34 to slide, thereby achieving movement of the clamp 3 along the Z-axis direction. When the slider 22 slides to the predetermined position, the locking piece 23 presses against the guide rod 21, thereby limiting the sliding of the slider 22 and fixing the position of the clamp 3.

[0040] In this embodiment, the locking member 23 adopts a limiting bolt, which is screwed on the slider 22 and set in the direction of the guide rod 21. When it is necessary to limit the sliding of the slider 22, the limiting bolt is rotated to make the limiting bolt and the guide rod 21 tightly abut against the slider 22, thereby limiting the position of the slider 22. In other embodiments, the locking member 23 includes a cylinder and a locking rod. The locking rod has multiple limiting holes along the axial direction. After the locking rod passes through the slider 22 and abuts against the guide rod 21, the cylinder passes through the side wall of the slider and is inserted into the limiting hole, thereby limiting the movement of the locking rod and limiting the position of the slider 22. Example

[0041] The structure of this embodiment 2 is roughly the same as that of embodiment 1, and the difference lies in the improvement of the Z-axis translation mechanism 2 and the clamp 3.

[0042] Reference Figure 4 The Z-axis translation mechanism 2 includes a translation stage 24, a slide 25 and a differential head 26. The translation stage 24 is fixedly connected to the stage 1 along the Z-axis direction, the slide 25 is slidably connected to the translation stage 24, and the differential head 26 is fixed on the translation stage 24. The rotation of the differential head 26 drives the slide 25 to slide along the Z-axis direction. In this embodiment, the differential head 26 adopts a double-adjustment differential head 26. The double-adjustment differential head 26 has a coarse adjustment knob and a fine adjustment knob. By rotating the coarse adjustment knob, the slider 22 is driven to move quickly to the vicinity of the preset area, and then the position of the slide 25 is precisely adjusted by the fine adjustment knob.

[0043] The differential head 26 can be set on the top surface or bottom surface of the translation stage 24, so that the output end of the differential head 26 is directly fixedly connected to the slide 25, so that the differential head 26 drives the slide 25 to move along the Z-axis direction. The differential head 26 can also be set on the side wall of the translation stage 24, and through the reversing structure, the horizontal movement of the differential head 26 can be converted into the vertical sliding of the slide 25.

[0044] The number of clamps 3 can be multiple, and several clamps 3 can be arranged along the Z-axis. Arranging the clamps 3 along the Z-axis reduces bending of the optical fiber. A clamp support rod 34 is provided between each clamp 3 and the slide 25. The clamps 3 are fixed to the slide 25 via the clamp support rods 34. In this embodiment, the first pressure plate 31 and the clamp support rods 34 are integrally formed.

[0045] In this embodiment, two clamps 3 are provided. In other embodiments, the number of clamps 3 may be three, four, or any other number. The bottommost clamp 3 is used to clamp both the fiber probe and the optical fiber, while the remaining clamps are used to clamp the optical fiber. In other embodiments, the bottommost clamp 3 may also clamp the fiber probe alone, while the remaining clamps 3 clamp the optical fiber.

[0046] The longitudinal cross-section of the lowest clamp rod 34 is triangular, while the longitudinal cross-sections of the remaining clamp rods 34 are rectangular. Because the clamp 3 fixedly connected to the lowest clamp rod 34 is used to clamp the fiber optic probe, while the remaining clamps 3 are used to clamp the optical fiber, the lowest clamp rod is subject to greater force. Designing it in a triangular shape allows the lowest clamp rod 34 to provide more stable support for the lowest clamp 3. The remaining clamp rods 34 only clamp the optical fiber and are subject to less force, so designing them in a rectangular shape reduces their space occupation. Example

[0047] The structure of this embodiment 3 is substantially the same as that of embodiment 1 or embodiment 2, except that an adjustment component 4 is additionally provided.

[0048] Reference Figure 5 、 Figure 6 and Figure 7 A tool for conducting animal experiments using a fiber optic probe also includes an adjustment component 4 for adjusting the clamping force of the clamp 3. The adjustment component 4 includes a gasket 41 and an adjusting bolt 42. The gasket 41 is arranged between the elastic member 33 and the inner wall of the telescopic groove 311. The adjusting bolt 42 is screwed on the first pressure plate 31 and can be inserted into the telescopic groove 311 and abut against the gasket 41. When the clamping force of the clamp 3 needs to be increased, the adjusting bolt 42 is rotated, and the gasket 41 is pushed toward the second pressure plate 32 by the adjusting bolt 42, thereby reducing the distance between the gasket 41 and the second pressure plate 32, compressing the elastic member 33, thereby achieving the effect of increasing the clamping force between the second pressure plate 32 and the first pressure plate 31. Example

[0049] The structure of this embodiment 4 is substantially the same as that of embodiment 1, embodiment 2 or embodiment 3, except that a pressing sheet 5 is additionally provided.

[0050] Reference Figure 4A tool for conducting animal experiments using a fiber optic probe also includes a pressing plate 5 mounted on a stage 1. The pressing plate 5 presses down the animal sample, thereby reducing the possibility of the animal sample shaking during the experiment. In this embodiment, at least two pressing plates 5 are provided, with at least two pressing plates 5 pressing down on both sides of the animal sample, thereby further reducing the possibility of the animal sample shaking.

[0051] Furthermore, several pressing plates 5 are rotatably connected to the stage 1. When placing an animal sample, the pressing plate 5 can be rotated first to make room for the animal sample, and then the pressing plate 5 can be rotated to press the animal sample, thereby facilitating the fixation of the animal sample.

[0052] Furthermore, a placement groove 11 is provided on the stage 1, and the animal sample is placed in the placement groove 11. Through the setting of the placement groove 11, the placement position of the animal sample is limited, which facilitates the correspondence between the position of the animal sample and the optical fiber probe, and reduces the need to repeatedly adjust the position of the animal sample.

[0053] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
