Description

Technical Field

[0002] Preclinical imaging in small animals is crucial for early disease diagnosis. Neurological diseases often cause retinal tissue damage, manifesting as lesions within the retinal layer at a very early stage. Therefore, experimental studies using the identification of structural changes in the retinal layer of animals such as fish, mice, and rats to diagnose diseases are essential.

[0003] When conducting ophthalmic experiments on small animals using external equipment, such as acquiring fundus images, ophthalmic experimental auxiliary equipment is needed to fix the anesthetized animal's body and head before acquiring the fundus images using appropriate external acquisition devices. However, the imaging area of ​​the animal's eyeball needs to be adjusted during the experiment. Current technology mainly relies on manual adjustment of the animal's eyeball position by the experimenter, which has poor adjustment precision and leads to low experimental efficiency. Furthermore, some complex adjustment mechanisms are not only expensive but also cumbersome to operate.

[0004] Therefore, how to improve the accuracy of position adjustment and increase experimental efficiency is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0052] The core of this invention lies in providing an ophthalmic imaging auxiliary adjustment device to improve position adjustment accuracy and experimental efficiency.

[0053] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the embodiments below are not limited to those necessary for the solution of the utility model as described in the claims. It should be noted that, for ease of description, only the parts relevant to the utility model are shown in the drawings. Unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0054] like Figure 1 As shown, the ophthalmic imaging auxiliary adjustment device disclosed in this embodiment includes a first displacement module 100, a second displacement module 200, an R-axis rotation module 300, a pitch rotation module 400, and an animal tray 500. The first displacement module 100 can output movement in a first direction and a second direction. After the first displacement module 100 is placed on a horizontal plane, it can output movement in two perpendicular directions within the horizontal plane, thereby enabling adjustment at any position within the horizontal plane (any position refers to any position within the adjustment range of the first displacement module 100).

[0055] The second displacement module 200 is disposed at the output end of the first displacement module 100 to drive the second displacement module 200 to move along the first direction and the second direction. The first displacement module 100 can adjust the position of the second displacement module 200 in the horizontal plane. The second displacement module 200 can output a third-direction position adjustment. If the first direction, the second direction, and the third direction are perpendicular to each other, then the second displacement module 200 can adjust its position in the vertical direction. The second displacement module 200 is provided with a coarse adjustment mechanism and a fine adjustment mechanism, which can control the speed at which the second displacement module 200 moves along the third direction, making the position adjustment more precise.

[0056] The R-axis rotation module 300 is disposed at the output end of the second displacement module 200 to drive the R-axis rotation module 300 to move along a third direction. The R-axis rotation module 300 can be selected from commonly used R-axis rotation modules in the prior art. This embodiment does not limit its specific structure.

[0057] The pitch rotation module 400 is located at the output end of the R-axis rotation module 300 to drive the pitch rotation module 400 to rotate in a plane. The rotation output directions of the pitch rotation module 400 and the R-axis rotation module 300 are perpendicular. The R-axis rotation module 300 can drive the pitch rotation module 400 to rotate in a plane, allowing the experimental animal's eyes to rotate horizontally with its body. The pitch rotation module 400 can also adjust the experimental animal's eyes to rotate in the pitch direction with its body.

[0058] An animal tray 500 is located at the output end of the pitch-rotation module 400. The pitch-rotation module 400 can drive the animal tray 500 to pitch and swing, and the animal tray 500 is used to fix the experimental animals. Depending on the experimental animals, the corresponding animal tray 500 can be installed on the output end of the pitch-rotation module 400.

[0059] The ophthalmic imaging auxiliary adjustment device provided by this utility model can perform parallel displacement of the animal tray 500 in three directions in space through the first displacement module 100 and the second displacement module 200, thereby realizing the position adjustment of the animal in the three-dimensional space to facilitate the adjustment of the animal's eyeballs to a suitable observation position. Simultaneously, the R-axis rotation module 300 and the pitch rotation module 400 can drive the animal tray 500 to rotate in two planes, adjusting the horizontal and pitch angles of the experimental animal, thereby adjusting the experimental animal's eyeballs to a suitable angle. This utility model can achieve rapid and precise adjustment of the position and angle of the experimental animal's eyeballs, with higher adjustment accuracy, which can improve experimental efficiency.

[0060] like Figure 2 As shown, in this embodiment, the first displacement module 100 includes a first displacement base 101, a first direction slider 102, and a second direction slider 103. The first direction slider 102 is slidably engaged with the first displacement base 101 along a first direction; the second direction slider 103 is slidably engaged with the first direction slider 102 along a second direction. The sliding directions of the first direction slider 102 and the second direction slider 103 can be guided by corresponding guiding mechanisms. The driving device that drives the sliding of the first direction slider 102 and the second direction slider 103 can be arbitrary, such as a gear and rack mechanism, a lead screw mechanism, or any other driving mechanism capable of linear displacement.

[0061] The second displacement module 200 is disposed on the second direction slider 103. The second displacement module 200 can be adjusted to move in the horizontal plane along the first and second directions through the first displacement module 100, thereby adjusting the position of the experimental animal's eyeball in the horizontal plane.

[0062] Furthermore, the first displacement module 100 may also include a first control knob 104 and a second control knob 105, which serve as drive inputs for the movement of the first direction slider 102 and the second direction slider 103. One of the first control knobs 104 and 105 controls the reciprocating movement of the first direction slider 102, and the other controls the reciprocating movement of the second direction slider 103. An operator can control the movement of one of the first direction sliders 102 and 103 by rotating the first control knob 104, and control the movement of the other of the first direction sliders 102 and 103 by rotating the second control knob 105. In this embodiment, both the first control knob 104 and the second control knob 105 control the movement of the sliders via gears.

[0063] like Figure 3 As shown, in this embodiment, the second displacement module 200 includes a second displacement base 201, a third-direction guide seat 202, a third-direction slider 203, and a third-direction adjustment knob. The second displacement base 201 is disposed at the output end of the first displacement module 100; specifically, the second displacement base 201 is disposed on the second-direction slider 103.

[0064] The third-direction guide seat 202 is fixed to the second displacement base 201. The third-direction slider 203 slides along the third direction and is engaged with the third-direction guide seat 202. The R-axis rotation module 300 is mounted on the third-direction slider 203. A third-direction guide part can be provided between the third-direction slider 203 and the third-direction guide seat 202 to guide the movement of the third-direction slider 203. The driving mechanism that drives the third-direction slider 203 to move along the third direction can be a gear and rack mechanism or a lead screw mechanism, etc.

[0065] The third-direction adjustment knob serves as an input component, controlling the reciprocating sliding of the third-direction slider 203 along the third direction. When the drive mechanism that drives the third-direction slider 203 to move along the third direction can be a gear and rack mechanism, the third-direction adjustment knob drives the input gear of the gear and rack mechanism to rotate, which in turn drives the third-direction slider 203 to reciprocate along the third direction via the rack.

[0066] Furthermore, the third-direction adjustment knob includes a coarse adjustment handwheel 204 and a fine adjustment handwheel 205 for controlling the third-direction slider 203 to reciprocate along the third direction, wherein the adjustment speed of the coarse adjustment handwheel 204 is greater than the adjustment speed of the fine adjustment handwheel 205.

[0067] Twisting the coarse adjustment handwheel 204 can make the third-direction slider 203 move at a faster speed. That is, when the coarse adjustment handwheel 204 rotates one revolution, the third-direction slider 203 moves a larger distance. In other words, the power is transmitted from the coarse adjustment handwheel 204 to the third-direction slider 203 through the first gear and rack mechanism.

[0068] Turning the fine-tuning handwheel 205 causes the third-direction slider 203 to move at a slower speed. That is, one rotation of the fine-tuning handwheel 205 results in a smaller movement distance for the third-direction slider 203. This is because the power is transmitted from the fine-tuning handwheel 205 to the third-direction slider 203 via the second gear and rack mechanism. The transmission ratio of the second gear and rack mechanism is larger than that of the first gear and rack mechanism, meaning the second gear and rack mechanism can output a greater deceleration effect, causing the third-direction slider 203 to move at a slower speed, thus achieving precise fine-tuning. It should be noted that the racks in the first and second gear and rack mechanisms can use the same rack, and some gears can also be shared. For example,... Figure 4 As shown, a first gear 207 and a rack 208 are provided on the third-party sliding block 203 and the third-party guide seat 202. The first gear 207 and the rack 208 can mesh and transmit power to each other. For example, the rack 208 can be set on the third-party sliding block 203, and the first gear 207 can be rotatably supported on the third-party guide seat 202, so that rotating the first gear 207 can drive the rack 208 and the third-party sliding block 203 to move. The second gear 209 in the first gear and rack mechanism is fixedly connected to the first gear 207 through the hollow shaft 211. The coarse adjustment handwheel 204 drives the first gear 207 to rotate by controlling the second gear 209. That is, the coarse adjustment handwheel 204 is connected to the second gear 209 for driving its rotation. The third gear 210 in the second gear and rack mechanism is connected to the hollow shaft 211 via a rotating shaft 212. For example, the rotating shaft 212 can be inserted inside the hollow shaft 211 and connected to it internally. The fine adjustment handwheel 205 drives the hollow shaft 211 and the first gear 207 to rotate by controlling the third gear 210. The transmission ratio between the second gear 209 and the first gear 207 is smaller than the transmission ratio between the third gear 210 and the first gear 207. The third gear 210 can be a gear set to achieve a greater speed reduction effect.

[0069] Furthermore, the third-party directional adjustment knob also includes a damping knob 206 for controlling the displacement adjustment resistance. Adjusting the damping knob 206 can change the load capacity of the third-party directional slider 203. Those skilled in the art can adjust the movement damping of the third-party directional slider 203 according to their needs through the damping knob 206. Specifically, the clamping force of the damping knob 206 pressed against a certain input gear in the first and second gear rack mechanisms can be adjusted by adjusting the damping knob 206. A friction plate that cooperates with the damping knob 206 can be set on the input gear to increase the friction, thereby changing the rotational resistance of the coarse adjustment handwheel 204 and the fine adjustment handwheel 205, and thus adjusting the movement damping of the third-party directional slider 203.

[0070] It should be noted that the first displacement module 100 and the second displacement module 200 can also be selected from the horizontal displacement module and the vertical displacement module commonly used in the prior art.

[0071] like Figure 5 As shown, in this embodiment, the R-axis rotation module 300 may include an R-axis mounting base 301 and an R-axis rotation base 302. The R-axis rotation base 302 can rotate around the rotation axis, so that the R-axis rotation base 302 can rotate in the plane formed by the first direction and the second direction.

[0072] The R-axis mounting base 301 is located at the output end of the second displacement module 200, i.e., fixed on the third displacement slider 203. The pitch rotation module 400 is located on the R-axis rotation module 300, thereby allowing the pitch rotation module 400 to rotate in the horizontal plane. It should be noted that the R-axis rotation module 300 can be an R-axis rotation module 300 with a built-in damper, allowing the R-axis rotation base 302 to hover at any horizontal angle and remain stable.

[0073] like Figure 6 and Figure 7 As shown, in a specific embodiment of this utility model, the pitch rotation module 400 may include a pitch base 401, a lead screw handwheel 406, a pitch rotation spindle 405, and an output gear 404. The pitch base 401 is located at the output end of the R-axis rotation module 300, i.e., it is mounted on the R-axis rotation base 302.

[0074] The lead screw handwheel 406 is connected to the input gear 402 via a drive shaft, which is rotatably supported on the pitch base 401. The pitch rotation spindle 405 is rotatably supported on the pitch base 401, and the output gear 404 is fixed on the pitch rotation spindle 405 and meshes with the input gear 402.

[0075] The operator can rotate the input gear 402 by turning the screw and handwheel 406. Since the input gear 402 meshes with the output gear 404, the output gear 404 will rotate along with the input gear 402, and simultaneously drive the pitch rotation main shaft 405 to rotate (by designing the output gear 404 as a sector gear, the rotation angle of the pitch rotation main shaft 405 can be limited; in this embodiment, the rotation angle range of the pitch rotation main shaft 405 can be designed to be between ±60°). Since the animal tray 500 is fixed on the pitch rotation main shaft 405, it will rotate along with the pitch rotation main shaft 405, thereby causing the experimental animal's eyeballs to pitch and sway.

[0076] Furthermore, the pitch rotation module 400 may also include a damper gear 403, which is rotatably mounted on the pitch base 401 and meshes with the input gear 402. When the screw handwheel 406 is turned, the input gear 402 is driven to rotate. Since the input gear 402 meshes with both the output gear 404 and the damper gear 403, it not only drives the output gear 404 to rotate but also drives the damper gear 403, thereby increasing the damping of the screw handwheel 406 and ensuring that the experimental animal can hover and remain stable at the corresponding angle.

[0077] like Figure 8 As shown, in this embodiment, the animal tray 500 may include a tray body 502 and a tray quick-release body 501. The tray body 502 is used to support and fix the experimental animals, and the tray quick-release body 501 has a quick-release hole, which is sleeved on the pitch and rotation main shaft 405 and locked by a set screw 503. The tray body 502 is disposed on the tray quick-release body 501.

[0078] The end of the pitch-rotation spindle 405 can have a profiled structure, and the quick-release hole is a profiled hole that matches the profiled structure of the end of the pitch-rotation spindle 405, so that the fit between the two can transmit torque after the pitch-rotation spindle 405 is inserted into the quick-release hole. The tray quick-release body 501 is fixed to the pitch-rotation spindle 405 by a set screw 503 to prevent the tray quick-release body 501 from disengaging from the pitch-rotation spindle 405 along its axial direction. The set screw 503 can be a ball screw or other types of fasteners.

[0079] When the set screw 503 uses a glass ball screw, the quick-release body 501 of the animal tray is directly inserted into the pitch and rotation spindle 405 through its quick-release hole. The glass ball screw is compressed by the pitch and rotation spindle 405, and the spring force prevents the animal tray 500 from moving axially along the pitch and rotation spindle 405. Furthermore, the animal tray 500 is easier and quicker to assemble and disassemble. This embodiment uses a quick-release structure between the animal tray 500 and the pitch and rotation spindle 405, facilitating the replacement of different types and sizes of animal trays 500 to match different sizes of experimental animals.
