Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and in particular, relates to an intraocular pressure measurement component. Background Art

[0002] Intraocular pressure (IOP) is the pressure of fluid inside the eye, which can be elevated due to anatomical problems, inflammation of the eye, genetic factors, as a side effect of medications, or during exercise. If IOP is elevated, it can cause increased pressure inside the eye and damage the optic nerve. Because abnormal pressure usually does not cause symptoms, changes in eye pressure cannot be felt on a daily basis, so it is important to check the pressure regularly.

[0003] Tonometer is an instrument for measuring intraocular pressure in human eyes, which can assist in the diagnosis of cataracts, glaucoma, etc. Common tonometer products include non-contact tonometer, applanation tonometer, contact piezoelectric tonometer, rebound tonometer, depression tonometer, etc.

[0004] The rebound tonometer, such as the Chinese authorized patent CN101190122B, includes a probe, a coil for driving the probe to move, and a probe seat for accommodating the probe. After the probe is magnetized, the front coil provides energy to make the probe start to move and hit the eye. When the probe hits the eye, the movement of the probe changes. Due to contact with the eye, the probe rebounds and moves backward. Among them, during use, the probe seat may cause performance degradation or damage due to many factors, such as the friction and collision between the probe and the probe seat during the process of the probe entering and exiting the probe seat many times, and the oxidation and aging of the probe seat itself, so it needs to be replaced regularly or irregularly. The replacement process generally requires opening the corresponding probe seat cover. When opening the probe seat cover, it is necessary to clamp and rotate the probe seat cover by hand. Since the probe seat cover is small and matches the assembly size between the probe seat, there is no fulcrum, which is very inconvenient when operated by hand, and the disassembly and assembly efficiency is low.

[0035] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0037] The applicant has found that in the related art, the performance of the probe seat may decline or be damaged due to many factors during use, and it needs to be replaced regularly or irregularly. The replacement process generally requires opening the corresponding probe seat cover. In the existing tonometer, the outer surface of the probe seat is a smooth frustum. In order to ensure safe use, the probe seat and the probe seat cover need to be screwed very tightly to ensure that the probe will not make abnormal sounds during operation due to loose fit. Due to the lack of appropriate tools, when opening the probe seat cover, it is necessary to clamp and rotate the probe seat cover by hand. Since the probe seat cover is small, it is very inconvenient to operate by hand, and the disassembly and assembly efficiency is low.

[0038] In view of the above problems, the applicant proposes an intraocular pressure measurement assembly, including an intraocular pressure measurement device and an optional disassembly and assembly mechanism, the intraocular pressure measurement device has a central axis, and the intraocular pressure measurement device includes a top shell, a cylinder, a probe seat and a probe seat cover, the cylinder extends upward from the top shell along the central axis to form a accommodating space, the probe seat and the probe seat cover are located in the cylinder, the probe seat, the probe seat cover and the cylinder are all coaxially arranged around the central axis, and at least one first clamping portion is provided on the probe seat cover; the disassembly and assembly mechanism is detachably connected to the intraocular pressure measurement device, and the disassembly and assembly mechanism includes a second clamping portion that is mutually clamped with the first clamping portion.

[0039] The intraocular pressure measurement assembly provided in the present application, through the mutual clamping of the first clamping part and the second clamping part, allows the user to disassemble and assemble the probe seat cover by rotating the disassembly and assembly mechanism, without having to directly twist the probe seat cover by hand, thereby improving the disassembly and assembly efficiency of the probe seat cover.

[0040] In order to better understand the present application, the intraocular pressure measurement assembly of the present application is described in detail below in conjunction with the accompanying drawings. In the accompanying drawings, for the convenience of drawing, the dimensions in the drawings are not necessarily proportional to the actual dimensions.

[0041] Embodiment 1:

[0042] Please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of the disassembly and assembly mechanism of some embodiments of the present application; Figure 2 A bottom view schematic diagram of the structure of an exemplary disassembly and assembly mechanism is shown; Figure 3 A partial exploded schematic diagram showing an exemplary intraocular pressure measurement device with the probe hidden; Figure 4 It is a schematic diagram of the structure of a probe seat cover of an intraocular pressure measuring device.

[0043] In some embodiments of the present application, the intraocular pressure measurement assembly includes an intraocular pressure measurement device 20 and an optional disassembly and assembly mechanism 10. Figure 3 and Figure 4 As shown, the intraocular pressure measuring device 20 has a central axis x, and the intraocular pressure measuring device 20 includes a probe seat cover 21, a cylinder 22, a probe seat 23 and a top shell 24, the cylinder 22 extends upward from the top shell 24 along the central axis x, thereby forming a receiving space, and the probe seat 23 and the probe seat cover 21 are located in the cylinder 22. The probe seat cover 21, the cylinder 22 and the probe seat 23 are all coaxially arranged around the central axis x, and at least one first clamping portion 211 is provided on the probe seat cover 21.

[0044] Specifically, the height of the probe seat 23 after being mounted on the top shell 24 exceeds the height of the cylinder 22. The structure of the probe seat cover 21 is as follows: Figure 3 As shown, it includes a horizontal molding boss 213 and an axial accommodation portion 214 intersecting (preferably perpendicular) and intersecting with the molding boss 213, and the axial accommodation portion 214 is used to accommodate the probe seat 23. The molding boss 213 includes adjacent molding portions 2131 and support portions 2132 along the extension direction of the central axis x. The outer diameter of the support portion 2132 matches the inner diameter of the cylinder 22, and is used to match and support the cylinder 22 during installation. The first clamping portion 211 is arranged on the molding portion 2131. Among them, the intersection of the axial accommodation portion 214 and the molding boss 213 means that the axial accommodation portion 214 passes through the molding boss 213 along the extension direction of the central axis x, and the molding boss 213 has partial axial accommodation portions 214 on both sides of the extension direction of the central axis x.

[0045] Furthermore, the outer peripheral surface of the top of the probe seat 23 away from the top shell 24 is provided with a first external thread 231, and the axial accommodating portion 214 is located at the part of the molding boss 213 away from the support portion 2132, and its inner peripheral surface is provided with a first internal thread (not shown) matching the first external thread 231, so that the probe seat 23 is threadedly connected to the probe seat cover 21, thereby fixing the probe seat cover 21.

[0046] It is explained here that since the probe seat 23 is a cylindrical structure around the central axis x, it has two circumferential surfaces, the circumferential surface of the outer wall of the cylinder is the outer circumferential surface, and the circumferential surface of the inner wall of the cylinder is the inner circumferential surface. It can be understood that in this application, the circumferential surfaces of other cylindrical structures can refer to the relevant description of the aforementioned probe seat.

[0047] Optionally, in one embodiment, the axial accommodation portion 214 further includes a portion located on the side of the molding boss 213 facing the support portion 2132 , and the portion is coaxially arranged with the probe seat 23 for accommodating and limiting the left-right displacement of the probe seat 23 .

[0048] Furthermore, in this embodiment, in a direction from the forming portion 2131 to the supporting portion 2132 , the outer diameter of the forming portion 2131 gradually increases until it is the same as the outer diameter of the supporting portion 2132 .

[0049] In an optional embodiment, the inner circumference of the cylinder 22 is provided with an inner convex structure (not shown) protruding toward the central axis at a position corresponding to the thickness of the support portion 2132, which is used to assist the probe seat cover 21 during installation. Optionally, the outer circumference of the support portion 2132 is a smooth outer surface.

[0050] In another optional embodiment, the outer circumference of the support portion 2132 is provided with a second external thread (not shown), and the inner circumference of the cylinder 22 is provided with a second internal thread (not shown) matching the second external thread, so that the probe seat cover 21 is threadedly connected to the cylinder 22.

[0051] Thus, through the above threaded connection, the probe seat cover 21, the probe seat 23 and the cylindrical object 22 of the top shell 24 of the intraocular pressure measurement device 20 are ensured to be fixedly connected. Those skilled in the art will understand that the bottom of the probe seat 23 is fixedly connected to other components. Figures 1 to 4 As shown, the disassembly mechanism 10 is detachably connected to the intraocular pressure measuring device 20, and the disassembly mechanism 10 includes a second clamping portion 111 that is mutually clamped with the first clamping portion 211. Specifically, as Figure 3 and 4 As shown, the first clamping portion 211 is disposed on the molding portion 2131 of the probe seat cover 21. For example, the first clamping portion 211 is a groove or a pit.

[0052] like Figure 1 and Figure 2 As shown, the disassembly and assembly mechanism 10 includes a connection seat 100 arranged around the first axis y and an annular sleeve 110 located at one end of the connection seat 100 in the extension direction of the first axis y, and the two are coaxially arranged along the first axis y, and the annular sleeve 110 is used to be sleeved with the cylinder 22 of the intraocular pressure measurement device 20. Specifically, the maximum outer diameter of the connection seat 100 is smaller than the outer diameter of the annular sleeve 110; the inner diameter of the annular sleeve 110 matches the outer diameter of the cylinder 22, and the height of the annular sleeve 110 is equivalent to the height of the cylinder 22.

[0053] Please refer to Figure 5 , Figure 5 A bottom view of another exemplary disassembly and assembly mechanism is shown, wherein the number of second clamping portions 111 is multiple, for example, three.

[0054] like Figure 1 , Figure 2 and Figure 5 As shown, in the disassembly and assembly mechanism 10, a connecting portion 120 matching the molding portion 2131 of the probe seat cover 21 is provided on the side of the connecting seat 100 facing the first axis y, and the molding portion 2131 is detachably connected to the connecting portion 120. The second clamping portion 111 is provided on the inner circumferential surface of the connecting portion 120 facing the first axis y, for example, the second clamping portion 111 is a first protrusion 112 protruding toward the first axis y. When the annular sleeve 110 is sleeved outside the probe seat cover 21, the first clamping portion 211 and the second clamping portion 111 are mutually clamped.

[0055] When the annular sleeve 110 is sleeved outside the probe base cover 21, the first axis y coincides with the central axis x of the intraocular pressure measuring device 20. When in use, the axis is the installation path direction of the probe.

[0056] like Figure 3 and Figure 4 As shown, when the intraocular pressure measuring device 20 is used, the probe (hidden) is installed along the central axis x of the intraocular pressure measuring device 20, and the probe seat cover 21 is fixedly connected to the probe seat 23 and the top shell 24 to protect the probe and limit the movement direction of the probe. Among them, the probe seat cover 21 is connected to the probe seat 23 by threads. The probe seat 23 and the probe seat cover 21 are both axially symmetrical figures, and when the probe is installed in the top shell 24, the central axes of the probe, the probe seat 23 and the probe seat cover 21 are collinear.

[0057] When the disassembly mechanism 10 disassembles the probe seat cover 21, the annular sleeve 110 is sleeved outside the cylindrical object 22 of the top shell 24, and the connecting portion 120 on the inner surface of the connecting seat 100 is sleeved with the outer circumference of the formed boss 213 of the probe seat cover 21. At this time, the first axis y of the annular sleeve 110 coincides with the central axis x of the probe seat cover 21, and the first clamping portion 211 and the second clamping portion 111 are mutually clamped. When the disassembly mechanism 10 rotates along the circumference of the first axis y, the probe seat cover 21 will also be driven to rotate along the circumference of its central axis x, and then removed from the probe seat 23. When the probe seat cover 21 is to be installed, the probe seat cover 21 is first sleeved on the probe seat 23, and then the annular sleeve 110 is sleeved on the outside of the cylindrical object 22, and the connecting part 120 inside the connecting seat 100 is sleeved on the outside of the probe seat cover 21, so that the first clamping part 211 and the second clamping part 111 are mutually clamped, and rotated in the opposite direction of the circumference of the above-mentioned first axis y, so as to drive the probe seat cover 21 to rotate and tighten the thread.

[0058] The disassembly mechanism 10 provided in this embodiment, through the annular sleeve 110 and the connecting portion 120 arranged around the first axis y on the connecting seat 100, when the connecting seat 100 is sleeved outside the probe seat cover 21, the annular sleeve 110 is sleeved outside the cylindrical object 22 of the top shell 24, and the connecting portion 120 is sleeved outside the probe seat cover 21, thereby increasing the axial connection length between the disassembly mechanism 10 and the intraocular pressure measurement device 20 and reducing the probability of shaking when the disassembly mechanism 10 is screwed. In addition, through the mutual clamping of the first clamping portion 211 and the second clamping portion 111, the user can disassemble the probe seat cover 21 by rotating the disassembly mechanism 10 to drive the probe seat cover 21 to rotate, without directly twisting the probe seat cover 21 by hand, thereby improving the disassembly efficiency of the probe seat cover 21.

[0059] In some optional embodiments, the second clamping portion 111 is located on the inner side of the connecting seat 100 toward the first axis y, for example, a first protrusion 112 protruding toward the first axis y and / or a first clamping groove (not shown) recessed away from the first axis y, and the first clamping portion 211 is, for example, a second clamping groove 212 matching the first protrusion 112 and / or a second protrusion (not shown) matching the first clamping groove.

[0060] The first protrusion 112 matches the second slot 212, which means that when the disassembly mechanism 10 is sleeved outside the probe seat cover 21, the first protrusion 112 can at least partially extend into the second slot 212 and be engaged with the second slot 212, so that the connection seat 100 and the probe seat cover 21 cannot rotate relative to each other along the circumference of the first axis y, but can only rotate synchronously. The first slot matches the second protrusion in the same way, which will not be repeated here.

[0061] In this embodiment, only the second clamping portion 111 is the first protrusion 112 protruding inwardly toward the first axis y, and the first clamping portion 211 is the second clamping groove 212 matching the first protrusion 112. However, in other embodiments, the second clamping portion 111 can also be the first clamping groove, and the first clamping portion 211 can be the second protrusion. In one embodiment, the first clamping portion 211 and the second clamping portion 111 are multiple groups relative to each other, for example, more than two groups, one of which is the first clamping groove matching the second protrusion, and the other group is the first protrusion matching the second clamping groove. In some optional embodiments, the first protrusion 112 is opposite to the second clamping groove 212, the first clamping groove is opposite to the second protrusion, the sum of the number of the first protrusion 112 is equal to the sum of the number of the second clamping groove 212 and corresponds one to one, and the sum of the number of the first clamping groove is equal to the sum of the number of the second protrusion and corresponds one to one.

[0062] Optional, such as Figure 4 and Figure 5 As shown, when the second clamping portion 111 includes only the first protrusion 112, a plurality of first protrusions 112 are evenly distributed around the first axis y, and at this time, the first clamping portion 211 includes only the second clamping groove 212, and a plurality of second clamping grooves 212 are evenly distributed around the central axis x of the probe seat cover 21. The same is true when the second clamping portion 111 includes only the first clamping groove and the first clamping portion 211 includes only the second protrusion.

[0063] Optionally, when the second clamping portion 111 includes both the first clamping groove and the first protrusion 112, multiple first clamping grooves and first protrusions 112 are evenly distributed around the first axis y, and the first clamping portion 211 includes both the second protrusion and the second clamping groove 212, multiple second protrusions and second clamping grooves 212 are evenly distributed around the central axis x of the probe seat cover 21, and the position of the second protrusion matches the position of the first clamping groove, and the position of the second clamping groove 212 matches the position of the first protrusion 112.

[0064] The disassembly and assembly mechanism 10 provided in this embodiment improves the connection strength when the first clamping portion 211 and the second clamping portion 111 are mutually clamped by making the sum of the number of the first protrusions 112 and the first clamping slots equal and one-to-one corresponding to the sum of the number of the second protrusions and the second clamping slots 212. By making the plurality of first protrusions 112 evenly distributed around the first axis y, the force balance of each position of the probe seat cover 21 in the circumferential direction is improved when the disassembly and assembly mechanism 10 disassembles and assembles the probe seat cover 21, thereby further improving the disassembly and assembly efficiency of the probe seat cover 21.

[0065] Embodiment 2:

[0066] Please refer to Figure 6 and Figure 7 , Figure 6 A bottom view schematic diagram showing another example of a disassembly and assembly mechanism; Figure 7 An example is shown with Figure 6 Schematic diagram of the structure of the probe seat cover matched with the disassembly and assembly mechanism.

[0067] like Figure 7 As shown, similar to Embodiment 1, the molding boss 213 of the probe seat cover 21 includes a molding portion 2131 and a supporting portion 2132, the supporting portion 2132 is cylindrical, and its outer circumference matches the inner circumference of the cylinder 22 of the top shell 24. Preferably, an annular inner convex structure is provided on the inner surface of the cylinder 22 to assist in receiving the supporting portion 2132, thereby receiving the probe seat cover 21. In this embodiment, the first clamping portion 211 is provided on the molding portion 2131 of the probe seat cover 21.

[0068] The difference from Example 1 is that the first clamping portion 211 is a cross-section formed on the outer edge of the molding portion 2131 away from the central axis x and intersecting (preferably perpendicular to) the supporting portion 2132. The number is at least one, and can be multiple. Preferably, the first clamping portions 211 formed by multiple cross-sections are connected to form a structure with a polygonal cross-section.

[0069] like Figure 6 As shown, matching with the first clamping portion 211, on the disassembly and assembly mechanism 10, the second clamping portion 111 is located on the inner surface of the connection seat 100, that is, the connection portion 120. In this embodiment, there is at least one second clamping portion 111, which is a section parallel to the central axis x / first axis y. The section matches the section of the first clamping portion 211 of embodiment 2. When there are multiple second clamping portions 111, it is preferred to enclose to form a polygonal structure, that is Figure 6 The first opening 113 has an orthographic projection shape in the extension direction of the first axis y that is the same as the orthographic projection shape of the first clamping portion 211 in the extension direction of the central axis x. In other words, the disassembly and assembly mechanism 10 can be configured such that the inner surface of the connecting portion 120 of the connecting seat 100 near the annular sleeve 110 is configured as a polygon, and the outer surface of the connecting portion 120 is composed of a plurality of cross-sections and the cross-sections are all parallel to or intersecting the first axis y of the disassembly and assembly mechanism 10.

[0070] Optionally, the orthographic projection shape of the first opening 113 in the extension direction of the first axis y includes a polygon, such as a hexagon, an octagon, etc. When the orthographic projection shape of the first opening 113 in the extension direction of the first axis y is an octagon, the orthographic projection shape of the first clamping portion 211 in the extension direction of the first axis y is also an octagon, the first clamping portion 211 can be understood as being similar to an octagonal nut, the annular sleeve 110 and the second clamping portion 111 can be understood as being similar to an octagonal sleeve, and when the octagonal sleeve is sleeved outside the octagonal nut, the octagonal sleeve can drive the octagonal nut to rotate by rotating in the circumferential direction.

[0071] In other embodiments, the orthographic projection shape of the first opening 113 in the extension direction of the first axis y may also be a special shape formed by a combination of an arc and a straight edge, as long as the projection shape of the first opening 113 is consistent with the projection shape of the first clamping portion 211 .

[0072] The disassembly and assembly mechanism 10 provided in this embodiment realizes the function that the second clamping portion 111 can be mutually clamped with the first clamping portion 211 when the annular sleeve 110 is sleeved outside the probe seat cover 21 by making the orthographic projection shape of the first opening 113 in the extension direction of the first axis y identical to the orthographic projection shape of the first clamping portion 211 in the extension direction of the first axis y.

[0073] The following takes Example 1 as an example to illustrate other structural features of the disassembly and assembly mechanism 10 of the present application. Figure 1 , Figure 2 , Figure 5 , Figure 8 , Figure 8 An example is shown Figure 2 Schematic diagram of the cross-sectional structure of the disassembly and assembly mechanism section.

[0074] according to Figure 2 and Figure 8 The connection seat 100 is provided with a connection portion 120 near the annular sleeve 110. In Embodiment 1, at least one second clamping portion 111 is provided on the inner surface of the connection portion 120 protruding toward the direction of the first axis y.

[0075] The disassembly and assembly mechanism 10 further includes a drive seat 300 and a waist portion 400, wherein the waist portion 400 is disposed between the drive seat 300 and the connection seat 100, and the drive seat 300, the waist portion 400 and the connection seat 100 are sequentially arranged along the extension direction of the first axis y. On the outer peripheral surface of the disassembly and assembly mechanism 10 away from the first axis y, the outer diameter of the drive seat 300 and the outer diameter of the connection seat 100 are gradually reduced toward the waist portion 400, thereby forming an hourglass shape on the outer surface. The outer circle radius of the cross section of the disassembly and assembly mechanism 10 in the direction perpendicular to the first axis y first gradually decreases and then gradually increases.

[0076] On the inner circumference of the disassembly and assembly mechanism 10 facing the first axis x, the drive seat 300, the waist portion 400 and the connection seat 100 together enclose a through hole 200. The cross section of the drive seat 300 in the direction perpendicular to the first axis y is a circular ring, the inner circle of the circular ring is formed by the through hole 200, and the outer circle of the circular ring is formed by the outer circumference of the drive seat 300 away from the through hole 200.

[0077] In the direction perpendicular to the first axis y, for the formed through hole 200, the smallest cross-section is set as the reorganization part 500. In the use state, in the extension direction of the first axis y, the reorganization part 500 is just in contact with the top of the axial accommodating part 214 of the probe seat cover 21 on one side of the intraocular pressure measuring device 20, or is 5mm away from the top of the axial accommodating part 214, so that the probe can enter the probe seat 23 immediately after the reorganization part 500 stands upright. For example, the distance between the lower surface of the reorganization part 500 and the top of the axial accommodating part 214 is 0-5mm. From the maximum cross-sectional position inside the drive seat 300 to the reforming part 500 (i.e., the minimum cross-sectional position of the through hole 200), the diameter of the circle formed by the cross-sectional area gradually decreases; and along the direction of the first axis y, the distance between the maximum cross-sectional position of the drive seat 300 and the reforming part 500 is greater than the distance between the maximum cross-sectional position of the drive seat 300 and the waist 400, that is, the reforming part 500 (i.e., the minimum position of the through hole 200) is located at the connection seat 100 below the waist 400. At this point, the probe is adjusted to coincide with the first axis y by tilting downward along the inner surface of the drive seat 300.

[0078] The diameter of the reorganization part 500 is greater than or equal to the diameter of the circular probe in the probe, so that when the connecting seat 100 is mounted on the outside of the probe seat cover 21, the user can freely sprinkle the probe from above the driving seat 300, and the probe will go from the through hole 200 along the inner wall toward the reorganization part 500, and be adjusted in the reorganization part 500 to be vertically toward the first axis y direction, and then extend from the opening on one side of the annular sleeve 110 and be installed in the probe seat 23.

[0079] Compared with the solution in which the minimum position is set at the waist 400, the above-mentioned selection of the minimum position of the through hole 200 increases the thickness and mechanical strength of the waist 400, and avoids the problem that the disassembly and assembly mechanism 10 is easily broken at the thinnest part. On the other hand, the waist 400 is set at the minimum position (reorganization part 500) higher than the through hole 200, which increases the travel distance of the probe and shortens the distance between the probe and the probe seat after the probe is vertically erected, so that the probe quickly enters the probe seat 23 after the probe is vertically erected, avoiding deviation from the central axis again.

[0080] The disassembly and assembly mechanism 10 provided in this embodiment has a central axis of the through hole 200 that coincides with the first axis y. When the connecting seat 100 is sleeved outside the probe seat cover 21, the central axis of the through hole 200 coincides with the central axis of the probe seat cover 21. The disassembly and assembly mechanism 10 assists the probe in being installed in the correct position of the intraocular pressure measuring device 20 without manual alignment, thereby improving the efficiency of probe replacement.

[0081] In the disassembly and assembly mechanism 10 (ie, in the through hole 200), between the rearrangement part 500 and the connection part 120, at least one fin-shaped structure 130 extends from the inner surface of the connection base 100 toward the first axis y. Those skilled in the art will appreciate that the fin-shaped structure 130 can be used in both Embodiment 1 and Embodiment 2.

[0082] A plurality of fin-shaped structures 130 are provided at a portion of the connection base 100 away from the connection portion 120. The fin-shaped structures 130 extend from the inner side of the connection base 100 in the direction of the first axis y, and are used to divide the area and guide the probe. In addition, the fin-shaped structures 130 also increase the weight of the connection base 100, so that the entire disassembly and assembly mechanism 10 is not easy to tip over.

[0083] Optionally, a handle portion 310 is provided on the surface of the driving seat 300 away from the connecting seat 100, and the cross section of the handle portion 310 is set to a polygonal structure. On the one hand, since the probe is sterilized and contacts the eyes when in use, the hand cannot touch the probe. When it is randomly sprinkled, the probe is easily scattered outside because the hand holds the part of the probe other than the probe, and the polygonal structure of the handle portion 310 provides a gathering function to prevent the probe from being scattered outside. On the other hand, the roughness of the handle portion 310 is greater than the surface of other positions of the driving seat 300, so that the user is not easy to slip when holding the handle portion 310. The handle portion 310 can be prepared by machining processes such as sandblasting and knurling on the surface of the driving seat 300, or the handle portion 310 can be formed by printing an uneven pattern on the surface of the driving seat 300.

[0084] The above is only a specific implementation of the present application. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the protection scope of the present application is not limited to this. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in this application, and these modifications or replacements should be included in the protection scope of this application.
