An auxiliary processing and measuring device for ex vivo eyeballs

Abstract

This utility model relates to the field of medical device technology and discloses an auxiliary processing and measurement device for ex vivo eyeballs. The device consists of a support component, a top cover component, and a horizontal calibrator. The support component has an independent receiving groove structure, and the surface of the top cover component forms a shallow arc-shaped liquid collection structure with an ex vivo eyeball fixing hole at the corresponding position of the receiving groove. The horizontal calibrator is integrated into a designated mounting position on either the support component or the top cover component. This utility model achieves eyeball positioning stability through the independent receiving groove design and the corresponding ex vivo eyeball fixing hole. The shallow arc-shaped top cover structure combines liquid collection function with adaptability to operating distance. The horizontal calibrator detects the orientation of the reference plane of the device, effectively solving the measurement error problem caused by the tilt of the operating plane during the processing and measurement of ex vivo eyeball specimens. This ensures precise alignment of the detection reference with the physiological axis of the eyeball, significantly improving the reliability and repeatability of ex vivo eyeball morphological parameter measurements.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an auxiliary processing and measuring device for isolated eyeballs, which is particularly suitable for eyeball positioning and posture correction during the testing of isolated eyeball parameters after ophthalmic surgical instrument operation. Background Technology

[0002] In the research and development of ophthalmic medical products, it is often necessary to use isolated animal eyeballs for related processing and testing. However, some operations during processing and testing can easily cause misalignment of the eyeball, resulting in positioning errors of key anatomical landmarks such as the corneal apex and pupil center that exceed clinically acceptable ranges. Furthermore, the uncontrolled posture of the operating plane during testing, such as the lack of corresponding posture monitoring in the eyeball fixation device, can lead to significant measurement data deviations when the angle between the device's reference plane and the horizontal plane exceeds 2°. Therefore, it is necessary to design a device that can assist in the processing and measurement of isolated eyeballs. Utility Model Content

[0003] This invention provides an auxiliary processing and measuring device for ex vivo eyeballs, which can at least solve one of the problems pointed out in the background art.

[0004] An auxiliary processing and measuring device for ex vivo eyeballs includes:

[0005] The supporting component has a receiving groove on its top for accommodating the eyeball;

[0006] The top cover assembly is fitted onto the outer periphery of the support assembly via a threaded connection structure, and a fixed hole for the detached eyeball corresponding to the bearing axis is provided at its center; and

[0007] A leveling device, mounted on the load-bearing assembly or top cover assembly;

[0008] The top cover assembly and the load-bearing assembly are connected by threads.

[0009] Preferably, the bearing assembly includes a bearing portion and a connector, the receiving groove is formed on the top of the bearing portion, and the connector and the top cover assembly are respectively provided with mutually cooperating external threads and internal threads.

[0010] In some possible implementations, the top cover assembly and the support assembly are connected by snap-fit.

[0011] In some possible implementations, the top cover assembly and the support assembly are elastically expanded and fixedly connected by plastic springs.

[0012] In some possible implementations, the top cover assembly is connected to the support assembly via fasteners.

[0013] In some possible implementations, the support and the connector are an integral structure.

[0014] In some possible implementations, the support and the connector are separate structures.

[0015] Preferably, the connector has a through groove, and the bearing part has a snap-fit ​​structure. The snap-fit ​​structure engages within the step of the through groove to connect the bearing part and the connector.

[0016] Preferably, the snap-fit ​​structure consists of two elastic clips connected to the load-bearing part. By pressing the two elastic clips, the outer radii of the two elastic clips can be changed from being larger than the through groove to being smaller than the through groove. The through groove has an inner wall stepped surface, and the two elastic clips can be snapped onto the stepped surface, forming a double limit in both axial and radial directions, thereby achieving rapid clamping and precise alignment of the load-bearing part and the connecting part.

[0017] Preferably, the top of the top cover assembly has an inwardly concave arc-shaped groove that communicates with the fixation hole for the detached eyeball.

[0018] Preferably, the contact surface between the top cover assembly and the eyeball is an outwardly concave arc-shaped groove II, which communicates with the fixation hole of the detached eyeball.

[0019] Preferably, the bottom of the bearing assembly has a receiving groove, in which the leveling instrument is installed.

[0020] Compared with the prior art, the beneficial effects of this utility model are: through the coordinated design of the independent receiving groove and the fixation hole of the ex vivo eyeball, this utility model controls the offset of the physiological axis of the eyeball from the measurement reference to within 0.2mm, which significantly improves the positioning accuracy of the corneal apex. Its coordinated design ensures that the position of the ex vivo eyeball is relatively fixed during the rotation and locking process.

[0021] In addition, the top cover assembly has a shallow circular cross-section design, which combines liquid collection function with adaptability to operating distance. This effectively solves the problems of center positioning deviation and surface wetting control of the isolated eyeball during the measurement process using measuring equipment after the isolated eyeball has been operated by surgical instruments or medical instruments.

[0022] In addition, the orientation of the reference plane of the horizontal correction system effectively solves the measurement error problem caused by the tilt of the operating plane during the processing and measurement of ex vivo eyeball specimens, ensuring the precise alignment of the detection reference with the physiological axis of the eyeball, and significantly improving the reliability and repeatability of the measurement of morphological parameters of ex vivo eyeballs.

[0023] Meanwhile, this utility model uses a modular design, which makes it more convenient to operate. The top cover component and the load-bearing component are connected by threads, which allows for quick replacement of the detached eyeball (single-hand operation time ≤5s). The split load-bearing component supports quick assembly and disassembly. The elastic snap-fit ​​structure still maintains effective limit after 50 cycle tests, which significantly improves the equipment maintenance efficiency and reliability. Attached Figure Description

[0030] The following detailed description of a specific embodiment of the present invention, in conjunction with the accompanying drawings and examples, is provided. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the invention, not the entire structure.

[0031] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Example 1

[0033] like Figures 1 to 3As shown in the figure, the present invention provides an auxiliary processing and measuring device for ex vivo eyeballs, including a support component 1 and a top cover component 2. The support component 1 has a receiving groove 3 for accommodating the eyeball, and the top cover component 2 is sleeved on the support component 1. The top cover component 2 and the support component 1 are connected by threads. The top cover component 2 has an ex vivo eyeball fixing hole 4 corresponding to the receiving groove 3. The diameter of the ex vivo eyeball fixing hole 4 is smaller than the diameter of a conventional animal eyeball, but slightly larger than the transverse diameter of the cornea of ​​a conventional animal eyeball.

[0034] Specifically, the support component 1 in this embodiment includes a support part 11 and a connector 12. The receiving groove 3 is opened on the top of the support part 11. The connector 12 and the top cover component 2 are respectively provided with mutually cooperating external threads and internal threads to realize the threaded engagement between the two. The eyeball is fixed by tightening the top cover component 2.

[0035] Specifically, by controlling the thread depth of the connector 12 and the top cover assembly 2, the intraocular pressure of the isolated eyeball can be controlled;

[0036] The supporting part 11 and the connecting part 12 can be an integral structure or a separate structure. This embodiment takes an integral structure as an example.

[0037] The top of the top cover assembly 2 has an inwardly concave arc groove 5, and the contact surface between the top cover assembly 2 and the eyeball is an outwardly concave arc groove 6. Both the arc groove 5 and the arc groove 6 are connected to the fixation hole 4 of the excised eyeball. Since there are certain requirements for the wetness of the eyeball surface during the detection process, the arc groove 5 can realize the function of collecting liquid on the wet eyeball surface. In addition, it also ensures the universality of most eyeball surface apexes relative to the operating distance of the surgical instruments used for detection.

[0038] Example 2

[0039] like Figure 3 As shown, this embodiment proposes an auxiliary processing and measuring device for ex vivo eyeballs based on embodiment one. This embodiment also includes a horizontal calibrator 8, which is installed on the support component 1 or the top cover component 2. This embodiment takes the installation on the support component 1 as an example.

[0040] Specifically, the bottom of the bearing component 1 has a receiving groove 7, and the level calibrator 8 is installed in the receiving groove 7. The levelness can be determined by the position of the bubble in the level calibrator 8, thereby reducing subsequent measurement errors. In this embodiment, the level calibrator 8 is only used to determine whether the device is level and does not have a leveling function. Leveling is achieved by using an external device, which will not be described in detail here.

[0041] Example 3

[0042] like Figures 1 to 4As shown, this embodiment proposes an auxiliary processing and measurement device for ex vivo eyeballs based on embodiment one or embodiment two. The carrier component 1 in this embodiment is a split structure. Specifically, the connector 12 has a stepped through groove 9, and the carrier part 11 has a snap-fit ​​structure. The snap-fit ​​structure is engaged in the step of the through groove 9 to realize the connection between the carrier part 11 and the connector 12.

[0043] The snap-fit ​​structure consists of two elastic clips 101 connected to the bearing part 11, with a gap between them. By pressing the two elastic clips 101, the two elastic clips 101 can be brought together inward (the outer radius of the two elastic clips 101 changes from being greater than the through groove 9 to being less than the through groove 9), and then they can be inserted into the through groove 9. In addition, the through groove 9 has a stepped surface 10. When the two elastic clips 101 reach the stepped surface 10, they expand outward under their own elasticity and can be snapped onto the stepped surface 10.

[0044] This split design allows for separation of the two components compared to an integrated structure, enabling the replacement of the support portion 11 with different sized support grooves, making it suitable for measuring different eyeball sizes.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit and essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
