Description

Technical Field

[0001] This invention relates to the technical field of ophthalmic teaching and training equipment, and in particular to an animal eyeball fixation device. Background Technology

[0002] Ophthalmology is a delicate discipline, and a qualified ophthalmic surgeon needs to practice extensively with animal eyes, including pig eyes and rabbit eyes.

[0003] In practice, the eyeball is usually fixed to a foam pad by piercing the conjunctival surface of the four quadrants with a pin. However, this method is unstable, and the animal's eyeball is not completely fixed relative to the foam pad. If the eyeball is not properly fixed, adjustments are needed, which is inconvenient. Another method is to use a hollow tube to hold the animal's eyeball in the hole to fix it. However, each eyeball is different in size and diameter. Either the eyeball is too large, which excessively compresses the eyeball and causes severe deformation, or the eyeball is too small, which causes the eyeball to slip and is difficult to fix. During training, eyeball movement is required to achieve a good eye position for surgical practice in order to achieve different eye positions. However, the existing fixation methods are inconvenient to adjust the eye position after fixation.

[0004] Therefore, a device is needed that can flexibly adjust the eye position and prevent excessive pressure on the eyeball. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides the following technical solution: An animal eyeball fixation device includes a base plate, a negative pressure pump, and a conduit. A movement platform is provided on the base plate, and a fixator is detachably installed on the movement platform. The fixator is connected to the negative pressure pump through the conduit. A collection tray is placed on the base plate below the fixator.

[0006] Furthermore, the base plate has an installation groove, and the motion platform is installed in the installation groove. The motion platform includes a rocker arm, a rotating plate, and a rotating frame. The rotating plate and the rotating frame are installed in the installation groove in a cross-rotational manner. A sliding groove is provided on the rotating plate, and the rocker arm passes through the sliding groove and is rotatably connected to the rotating frame.

[0007] Furthermore, the two ends of the rotating plate are rotatably connected to the inner wall of the mounting groove via a fixed longitudinal axis; the two ends of the rotating frame are rotatably connected to the mounting bracket via a fixed transverse axis; and the rotatable connection between the rocker arm and the rotating frame is coaxial with the transverse axis.

[0008] Furthermore, an X motor and a Y motor are fixedly installed inside the base plate corresponding to the longitudinal axis and the transverse axis, respectively, and the X motor and the Y motor drive the rotating plate and the rotating frame to rotate.

[0009] Furthermore, a rotating sleeve is coaxially mounted above the rocker arm, and the lower end of the retainer is inserted into the rotating sleeve. Bolts are provided on the rotating sleeve to prevent the retainer from coming out of the rotating sleeve.

[0010] Furthermore, the upper end of the fixator is a bowl-shaped structure, and the lower end of the fixator is a rod-shaped structure. The bottom of the bowl-shaped structure has a cavity design, and several suction holes are opened on the bottom of the bowl-shaped structure to communicate with the cavity. The rod-shaped structure is provided with a negative pressure channel to communicate with the cavity, and the conduit is connected to the negative pressure channel.

[0011] Furthermore, the suction hole includes a main suction hole located in the center and several secondary suction holes surrounding the main suction hole.

[0012] Furthermore, a transition bottle is connected to the outside of the negative pressure pump via a conduit, and a sealing cap is provided on the transition bottle. The fixture is connected to the transition bottle via a conduit passing through the sealing cap, and the negative pressure pump is connected to the transition bottle via a conduit passing through the sealing cap.

[0013] Furthermore, the collecting plate is a circular plate with a hollow center, and an elastic flexible sleeve is fixedly fitted on the inner ring of the collecting plate. The upper end of the flexible sleeve is sealed and fitted onto the outer wall of the rocker arm.

[0014] Furthermore, a slidably detachable support frame is provided on the base plate. The support frame includes a support plate and a telescopic rod. The extended end of the telescopic rod is fixedly connected to the support plate, and the lower end of the telescopic rod is slidably connected to the base.

[0015] Furthermore, a sliding groove is provided on the base plate, with one end of the groove being an open structure; a slider is fixedly installed at the lower end of the telescopic rod, and the slider slides along the sliding groove.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects: This invention features a motion platform installed in a mounting slot on the base plate, with a fixator detachably mounted on the rocker arm of the motion platform. The fixator is connected to a negative pressure pump. In use, the eyeball is placed within the bowl-shaped structure of the fixator, and the negative pressure of the pump draws the eyeball in, facilitating fixation. An X-motor drives a rotating plate to rotate left and right around its longitudinal axis, causing the rocker arm to swing left and right, thus adjusting the eyeball's position. A Y-motor drives a rotating frame to rotate back and forth around its transverse axis, causing the rocker arm to swing back and forth, adjusting the eye position. The fixator is mounted in a rotating sleeve on the rocker arm, allowing it to rotate around the rocker arm's axis to adjust the eye position and achieve the ideal training eye position. This invention features an externally connected transition bottle via a conduit to the negative pressure pump. The transition bottle draws in and collects tissue fluid from the upper part of the eyeball, preventing the tissue fluid from flowing into the negative pressure pump. Cleaning is easy by simply disassembling the fixator and the transition bottle. A detachable support frame is also slidably mounted on the base plate to support the arm and prevent arm fatigue.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1:

[0021] In this embodiment, to address the current problem of unstable fixation during eye training by piercing the conjunctival surface of the eyeball through the four quadrants with pins and fixing it to a foam pad, and the inconvenience of adjusting the eyeball if it is not properly fixed, this embodiment proposes to fix the eyeball using negative pressure. This allows for easy adjustment by simply controlling the negative pressure. Please see Figure 1-7 An animal eyeball fixation device includes a base plate 1, a negative pressure pump 3, and a conduit 9. A movement platform 6 is mounted on the base plate 1, and a fixator 5 is detachably mounted on the movement platform 6. The fixator 5 is connected to the negative pressure pump 3 via the conduit 9. The upper end of the fixator 5 is a bowl-shaped structure, and the lower end is a rod-shaped structure. The bottom of the bowl-shaped structure has a cavity design, and several suction holes are formed on the bottom of the bowl-shaped structure, communicating with the cavity. A negative pressure channel is provided on the rod-shaped structure, communicating with the cavity. The conduit 9 is connected to the negative pressure channel. The suction holes include a central main suction hole and several secondary suction holes surrounding the main suction hole. In this embodiment, animal eyeballs of different sizes can be placed in the bowl-shaped structure at the upper end of the fixator 5. The negative pressure of the negative pressure pump 3 is used to suction and fix the eyeballs in the bowl-shaped structure. Fixing is convenient. The position of the fixed eyeballs can be adjusted simply by turning off the negative pressure. The negative pressure suction method reduces damage to the eyeballs. The secondary suction holes designed around the main suction hole can help to suction the sclera or connective tissue of the axial length at multiple points, making the fixation more stable.

[0022] Example 2:

[0023] According to Example 1, although eyeball fixation is achieved, training still requires specific eye positions. Therefore, a structure needs to be designed to adjust changes in eyeball position. Please see Figure 1-7 A motion platform 6 is provided on the base plate 1, and a fixture 5 is detachably installed on the motion platform 6. An installation groove 12 is provided on the base plate 1, and the motion platform 6 is installed in the installation groove 12. The motion platform 6 includes a rocker arm 61, a rotating plate 62, and a rotating frame 63. The rotating plate 62 and the rotating frame 63 are rotatably installed in the installation groove 12. A sliding groove is provided on the rotating plate 62, and the rocker arm 61 passes through the sliding groove and is rotatably connected to the rotating frame 63. In this embodiment, the two ends of the rotating plate 62 are rotatably connected to the inner wall of the mounting groove 12 via fixed horizontal axes; the two ends of the rotating frame 63 are rotatably connected to the mounting bracket via fixed vertical axes; the rotatable connection between the rocker arm 61 and the rotating frame 63 is coaxial with the vertical axis; an X motor 64 and a Y motor 65 are fixedly installed in the base plate 1 corresponding to the horizontal and vertical axes respectively, and the rotating plate 62 and the rotating frame 63 are driven to rotate by the X motor 64 and the Y motor 65 respectively; a rotating sleeve 611 is coaxially rotatably installed above the rocker arm 61, and the lower end of the fixing device 5 is inserted into the rotating sleeve 611, and the fixing device 5 is prevented from coming out of the rotating sleeve 611 by bolts provided on the rotating sleeve 611; In this embodiment, during use, the X motor 64 drives the rotating plate 62 to rotate left and right around the longitudinal axis, thereby causing the rocker arm 61 to swing left and right, realizing the left and right swing of the eyeballs on the fixator 5, and realizing the adjustment and change of the left and right eye positions; the Y motor 65 drives the rotating frame 63 to rotate back and forth around the horizontal axis, thereby causing the rocker arm 61 to swing back and forth, realizing the adjustment and change of the front and back eye positions, and the fixator 5 is installed in the rotating sleeve 611 that is rotatably set on the rocker arm 61, which can rotate around the axis of the rocker arm 61 to adjust the eye position and achieve the ideal training eye position; It should be noted that the aforementioned motion platform 6 is not limited to realizing forward and backward, left and right eye position changes; it can also realize multiple eye position adjustments such as left front, left back, right front, and right back by driving the rotating plate 62 to rotate left and right around the longitudinal axis by driving the rotating frame 63 to rotate forward and backward around the horizontal axis by driving the Y motor 65.

[0024] Example 3:

[0025] According to Examples 1-2, it was clinically found that due to prolonged use, animal eyeballs would develop an odor and require cleaning. Additionally, during suction, tissue fluid would be drawn into the catheter 9, contaminating the negative pressure pump 3. Therefore, to facilitate cleaning and prevent contamination of the negative pressure pump 3, the following design was implemented: Please see Figure 1-7 An animal eyeball fixation device includes a base plate 1, a negative pressure pump 3, and a conduit 9. A motion platform 6 is provided on the base plate 1, and a fixator 5 is detachably installed on the motion platform 6. The fixator 5 is connected to the negative pressure pump 3 through the conduit 9. A transition bottle 4 is connected to the negative pressure pump 3 through the conduit 9. A sealing cap is provided on the transition bottle 4. The fixator 5 is connected to the transition bottle 4 through the sealing cap via the conduit 9, and the negative pressure pump 3 is connected to the transition bottle 4 through the sealing cap via the conduit 9. In this embodiment, a transition bottle 4 is connected to the negative pressure pump 3 via a conduit 9. The transition bottle 4 can attract and collect tissue fluid from the upper end of the eyeball, preventing the tissue fluid from flowing into the negative pressure pump 3. Cleaning can be done simply by removing the fixator 5 and the transition bottle 4, making cleaning more convenient.

[0026] Example 4:

[0027] According to Examples 1-3, it has been clinically observed that during use, tissue fluid and other substances may flow down the outer wall of the fixator 5, causing contamination of the internal structure of the motion platform 6. Therefore, the following design was implemented to avoid contamination: Please see Figure 1-7 An animal eyeball fixation device includes a base plate 1, a negative pressure pump 3, and a conduit 9. A motion platform 6 is provided on the base plate 1, and a fixator 5 is detachably installed on the motion platform 6. The fixator 5 is connected to the negative pressure pump 3 through the conduit 9. A collection tray 8 is placed on the base plate 1 below the fixator 5. The collection tray 8 is a circular annular disc with a hollow center. An elastic flexible sleeve 7 is fixedly fitted on the inner ring of the collection tray 8, and the upper end of the flexible sleeve 7 is sealed and fitted onto the outer wall of a rocker arm 61. In this embodiment, the tissue fluid flowing down can be collected by the collection tray 8. The design of the flexible sleeve 7 allows the tissue fluid flowing down along the outer wall of the fixator 5 to flow into the collection tray 8 along the flexible sleeve 7, thus avoiding the tissue fluid from contaminating the internal structure of the motion platform 6. At the same time, the design of the flexible sleeve 7 does not affect the movement of the rocker 61 of the motion platform 6.

[0028] Example 5:

[0029] According to Examples 1-4, to reduce arm fatigue during training, please refer to... Figure 1-7 A slidable and detachable support frame 2 is provided on the base plate 1. The support frame 2 includes a support plate 21 and a telescopic rod 22. The extended end of the telescopic rod 22 is fixedly connected to the support plate 21, and the lower end of the telescopic rod 22 is slidably connected to the base. A sliding groove 11 is provided on the base plate 1, and one end of the sliding groove 11 is an open structure. A slider is fixedly provided at the lower end of the telescopic rod 22, and the slider slides along the sliding groove 11. The support frame 2 can support the arm and avoid arm fatigue.

[0030] Example 6:

[0031] According to Examples 1-5, such as Figure 8-9 As shown, in this embodiment, the position of the eyeball can be adjusted manually instead of using the X motor 64 and Y motor 65. Two hand-operated components 10 are provided on the base plate 1 corresponding to the rotating plate 62 and rotating frame 63. The two ends of the rotating plate 62 are rotatably connected to the inner wall of the mounting groove 12 via a fixed horizontal axis. The two ends of the rotating frame 63 are rotatably connected to the mounting bracket via a fixed vertical axis. One hand-operated component 10 is fixedly connected to the horizontal axis, and the other hand-operated component 10 is fixedly connected to the vertical axis. By rotating the two hand-operated components 10 respectively, the rotating plate 62 and rotating frame 63 can be driven to rotate, thus adjusting the position of the eyeball.
