Description

Technical Field

[0001] The invention belongs to the technical field of ophthalmic scleral inner wall tissue clearing instruments, and in particular relates to a controllably deformable clearing device for dissolved matter in an eyeball. Background Art

[0002] After enucleation, an appropriate implant is placed in the scleral cavity. Later, an artificial eye is installed for better mobility and appearance. Pigmented tissue remains on the inner surface of the sclera after surgery. If it is not cleaned in time, it will cause continuous inflammation after surgery and even affect the other eyeball to produce an inflammatory reaction. Studies have confirmed that the pigmented tissue and residual tissue of the corneal surface and subconjunctiva are the basis for the recurrence of enucleation. Therefore, thorough removal of excess pigmented tissue and residual tissue is a crucial factor in avoiding postoperative recurrence.

[0003] At present, circular blades are mainly used in clinical practice to scrape the residual leucorrhea tissue on the surface of the cornea and sclera. During the scraping operation, the circular blade needs to be moved back and forth on the same plane close to the cornea and sclera. Since the scraping depth of the blade is uncontrollable, it is easy to scratch the cornea and sclera, and even cause corneal and scleral lamellar lacerations; and it is easy to leave residual leucorrhea tissue, resulting in postoperative recurrence and hyperplasia of vitiligo scars; in addition, the scraping operation is cumbersome and inefficient.

[0004] Due to the atrophy of the soft tissue in the orbit after surgery, and the irregular concave surface of the sclera, the degree of depression in different positions is different, and the surface is not very flat, so it is difficult to grind and polish the inner surface of the sclera. The efficiency of the electric polishing method used in the existing technology cannot be significantly improved. Due to the irregular inner surface of the sclera, the main difficulty lies not in the rotation speed but in the accuracy of the position and the all-round polishing treatment, as well as avoiding damage to the inner surface of the sclera. There is currently a lack of effective tools. Summary of the invention

[0005] In view of the difficulty in removing residual pigmented tissue on the inner surface of the sclera after surgery, the present invention provides a controllable deformation remover for intraocular solution, which adapts to the inner surface of the sclera by controlling the different shapes of the polished end, so as to facilitate effective and efficient removal.

[0006] The solution of the present invention to the technical problem is: a controllable deformation remover of dissolved matter in the eyeball is adopted, the remover includes a handle, an extension rod and a grinding end, the grinding end includes a supporting component and an elastic deformation component, a grinding surface is provided on the outer side of the elastic deformation component, the supporting component is fixedly connected to the end of the extension rod, a transmission mechanism for driving the elastic deformation component to realize deformation is arranged inside the elastic deformation component, and a control mechanism for driving the transmission mechanism to move is arranged at the handle.

[0007] Specifically, one form of the elastic deformation component can be an elastic ring, and the support component includes two parallel support plates, a sleeve joint is fixed at the bottom, each support plate is a flat plate body with an approximately square structure, and the four top corners of the two support plates are fixed as a whole through four fixed shafts, and a support wheel is mounted on the outside of each fixed shaft. The four support wheels are respectively supported on the inner wall of the elastic ring to keep the elastic ring in its original circular or oblate state.

[0008] Specifically, one form of the transmission mechanism includes a horizontal traction hole, a horizontal guide wheel, a vertical traction hole, a guide wheel, left and right traction ropes, and upper and lower traction ropes located on the inner wall of the elastic ring, wherein the horizontal traction hole is located on the right side of the inner wall of the elastic ring, the horizontal guide wheel is installed on the left side of the inner wall of the elastic ring, the vertical traction hole is located on the lower side of the inner wall of the elastic ring, the vertical guide wheel is installed on the upper side of the inner wall of the elastic ring, the head ends of the left and right traction ropes are fixed in the horizontal traction hole, the left and right traction ropes are wrapped in the groove of the horizontal guide wheel, and the ends thereof are led out of the elastic ring. The head ends of the upper and lower traction ropes are fixed in the vertical traction hole, the upper and lower traction ropes are wrapped in the groove of the vertical guide wheel, and the ends thereof are led out of the elastic ring.

[0009] Specifically, one form of the control mechanism includes a pulley assembly installed at the handle position, wherein the ends of the left and right traction ropes and the upper and lower traction ropes are fixed as a whole and wrapped around the groove of the pulley assembly. The pulley assembly is rotated to drive the left and right traction ropes and the upper and lower traction ropes to move up and down respectively, thereby driving the transmission mechanism to cause the elastic ring to deform horizontally or vertically.

[0010] Among them, the rope pulley assembly is provided with a through hole at the axial center position of the rope pulley and a spline groove is provided on the inner wall of the through hole, so as to form a spline shaft hole, the inner side of which is matched with a spline shaft, and a shell spline shaft hole is provided on the inner wall of the handle shell, and the shell spline shaft hole can also match the spline shaft, and an extended shaft section is fixed to the left end of the spline shaft, and the outer end of the extended shaft section is led out from the handle shell, and an adjusting hand wheel is installed at the lead-out end, and a boss is provided between the shell spline shaft and the extended shaft section, and a boss is sleeved between the boss and the inner wall of the handle shell. A top spring is installed, so that, in a natural state, the spline shaft is pushed to the right by the top spring, so that the right end of the spline shaft can be matched and inserted into the spline shaft hole of the outer shell and cannot rotate. After pulling the handwheel outward, the spline shaft can also move outward in linkage, so that the right end of the spline shaft is separated from the spline shaft hole of the outer shell. At this time, the handwheel and the rope pulley are no longer locked, and the internal rope pulley can be driven to rotate by turning the handwheel. The rotation of the rope pulley can drive the left and right traction ropes and the upper and lower traction ropes to move up and down, thereby driving the elastic ring to deform.

[0011] In addition, the composite body of the elastic ring and the polished surface is in the shape of a flat ring or a curved ring.

[0012] Specifically, the same or different grinding components can be fixed on the outer sides of the support plates on both sides, for example, a fixed spherical friction surface is installed on the surface of the support plate on one side, and a fixed plate friction surface is installed on the surface of the support plate on the other side.

[0013] A transition shaft may be further fixed at a suitable position between the support plates on both sides, and a transition rope pulley may be sleeved on the transition shaft.

[0014] In addition, the transmission mechanism can also be that the ends of the left and right traction ropes and the upper and lower traction ropes are respectively connected to tension springs, the ends of the two tension springs are respectively fixed on the inner wall of the handle shell, a vertical strip hole is opened on the handle shell, and a slider is installed in the strip hole, so that the slider can only slide vertically along the strip hole, and any traction rope is fixed together with the slider, so that when the slider is driven upward or downward, it can drive the corresponding traction rope to move upward or downward.

[0015] Alternatively, the transmission mechanism may be provided with tension springs at the ends of the left and right traction ropes and the upper and lower traction ropes, respectively, and the ends of the two tension springs are respectively fixed on the inner wall of the handle housing. After any traction rope is cut off, the broken two ends are respectively fixed on the two inner ends of the main rocker arm and the slave rocker arm, and the two outer ends of the main rocker arm and the slave rocker arm are hinged together by a pin shaft, and a torsion spring is mounted on the outside of the pin shaft. The torsion spring makes the main rocker arm and the slave rocker arm in a naturally contracted state, and a longitudinal vertical plate is provided in the inner cavity of the handle housing, and the two inner ends of the main rocker arm and the slave rocker arm are also supported on the surface of the vertical plate, or the surface is set in the strip hole, and a pressing handle is fixed at the end of the active rod, and by pressing the pressing handle inward, the corresponding traction rope can be driven to move upward or downward.

[0016] Beneficial effects of the present invention:

[0017] The cleaner of the present invention is designed to solve the problem that the inner surface of the sclera is difficult to grind and polish due to different degrees of depression at different positions and the uneven surface. The grinding end of the distal end can be deformed by manual adjustment to adapt to different parts of the inner surface of the sclera, thereby improving the grinding effect and accuracy, and improving the grinding efficiency. There is no need to replace the instrument, and the operation is simple and convenient.

[0018] One way is to drive the elastic ring to achieve different degrees of deformation by rotating the adjustment hand wheel forward or backward. When the rope wheel is rotated clockwise, the upper and lower traction ropes move downward, and the left and right traction ropes move upward, so that the arcs on both sides of the elastic ring become larger and the arcs on the ends become smaller; when the rope wheel is rotated counterclockwise, the left and right traction ropes move downward, and the whole becomes slender, so that the arcs on both sides of the elastic ring become smaller and the arcs on the ends become larger; the upper and lower traction ropes move upward, and in the natural state, under the rebound effect of the elastic ring, the left and right traction ropes and the upper and lower traction ropes are balanced by the upper and lower traction forces, so that the elastic ring is in a perfect circle. In addition, the polished surface can have different performances of convex outward to meet the use requirements of different degrees of depression of the inner wall of the sclera.

[0019] The same or different grinding components are fixed on the outer sides of the support plates on both sides respectively. A fixed spherical friction surface is installed on the surface of one support plate, and a fixed plate friction surface 23 is installed on the surface of the other support plate to meet the use requirements of different parts.

[0020] When the ends of the left and right traction ropes and the upper and lower traction ropes are respectively connected with tension springs, pulling any traction rope downward or pushing any traction rope upward can drive the corresponding traction hole and traction wheel to shrink inward or expand outward, and automatically reset after loosening the traction rope.

[0021] When the elastic ring is changed into an elastic balloon, there is a friction layer on the outer surface of the elastic balloon. Driving any slider to move upward or downward can drive the corresponding traction rope to move telescopically, thereby realizing the deformation of the elastic balloon in the corresponding direction. When the elastic balloon 39 is deformed in any dimensional direction or in two or three dimensional directions at the same time, the remaining traction ropes can also cooperate with the deformation under the action of the tension spring.

[0022] After the driving sleeve is sleeved on the upper end of the handle, it can be matched and sleeved on the upper end of the handle and can slide axially. The inner end of the driving sleeve is sleeved on the upper end of the handle with a tension spring or a top spring, so that the driving sleeve can automatically reset after axial movement, and can realize individual and simultaneous control of one, two or three of the three sliders. It is only necessary to rotate the driving sleeve to the corresponding position of the corresponding mark, and move the driving sleeve downward or push it upward, which can improve the convenience of use.

DETAILED DESCRIPTION

[0043] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0044] Embodiment 1: A controllable deformation remover of dissolved matter in the eyeball is designed to solve the problem that the inner surface of the sclera is difficult to polish due to the different degrees of depression at different locations and the uneven surface. Figure 1 As shown, the cleaner comprises a handle 14, an extension rod 13 and an elastic ring 1 which are fixedly connected from bottom to top in sequence. The grinding surface 2 is fixed to the outer ring of the elastic ring 1 and is used as a grinding component to directly grind the inner surface of the sclera. The adjustment hand wheel 20 at the lower end of the handle 14 can drive the elastic ring 1 to deform when rotating in the forward or reverse direction, so as to achieve the following Figure 7 The different deformation degrees shown, in turn, enable the polished surface 2 to have different outward convex performances to meet the use requirements of different degrees of depression of the inner wall of the sclera.

[0045] like Figure 8 As shown, the elastic ring 1 and the grinding surface 2 can be designed as a flat ring shape or an arcuate ring shape, such as the arcuate ring friction surface 24 in the figure. The two different structural forms can be used alone or in combination.

[0046] like Figure 4 The specific structure inside the elastic ring 1 is shown, which includes the elastic ring 1, a polished surface 2, a horizontal traction hole 3, a horizontal guide wheel 4, a vertical traction hole 5, a vertical guide wheel 6, left and right traction ropes 7, upper and lower traction ropes 8, a support plate 9, a fixed shaft 10, a support wheel 11 and a sleeve joint 12.

[0047] Fig.11In the figure, the horizontal traction hole 3, the horizontal guide wheel 4, the vertical traction hole 5, and the vertical guide wheel 6 are respectively located on the inner wall of the elastic ring 1, wherein the horizontal traction hole 3 is located on the right side of the inner wall of the elastic ring 1, the horizontal guide wheel 4 is installed on the left side of the inner wall of the elastic ring 1, the vertical traction hole 5 is located on the lower side of the inner wall of the elastic ring 1, and the vertical guide wheel is installed on the upper side of the inner wall of the elastic ring 1. The horizontal guide wheel 4 and the vertical guide wheel 6 respectively include a wheel frame, an axle and a wheel, the wheel frame is fixed on the inner wall of the elastic ring 1, the axle is fixed on the wheel frame, the center hole of the wheel is installed on the axle, and the wheel is a V-shaped wheel.

[0048] like Fig.10 As shown, two parallel support plates 9 have sleeve joints 12 fixed at their bottoms. Each support plate is a plane plate body with a nearly square structure, and the four vertex positions of the two support plates are fixed as a whole through four fixed shafts 10. A support wheel 11 is sleeved on the outside of each fixed shaft 10. In addition, a transition shaft 25 can be fixed at a suitable position between the support plates 9 on both sides, and a transition rope pulley 26 is sleeved on it.

[0049] Will Fig. 9 The elastic ring 1 shown is Fig.10 After the support plate 9 is installed, Figure 2-Figure 4 As shown, four supporting wheels 11 are respectively supported on the inner wall of the elastic ring 1 to keep the elastic ring 1 in the original circular or oblate state.

[0050] Figure 4 It can also be seen that a traction rope is connected to each traction hole and guide wheel. Specifically, the head ends of the left and right traction ropes 7 are fixed in the horizontal traction hole 3, the left and right traction ropes 7 are wrapped in the groove of the horizontal guide wheel 4, and the ends of the left and right traction ropes 7 are led out from the sleeve joint 12. The head ends of the upper and lower traction ropes 8 are fixed in the vertical traction hole 5, the upper and lower traction ropes 8 are wrapped in the groove of the vertical guide wheel 6, and the ends of the upper and lower traction ropes 8 are led out from the sleeve joint 12.

[0051] Figure 4 As can be seen in the figure, the ends of the left and right traction ropes 7 and the upper and lower traction ropes 8 are fixed as a whole and are wrapped in the groove of the rope wheel 15. Therefore, when the rope wheel 15 is rotated, the left and right traction ropes 7 and the upper and lower traction ropes 8 can be driven to pull up and down respectively, that is, the following can be achieved: Figure 7 When the rope wheel 15 is rotated clockwise, the upper and lower traction ropes 8 move downward, and the left and right traction ropes 7 move upward. Figure 7 In the middle (a) state, when the rope wheel 15 is rotated counterclockwise, the left and right traction ropes 7 move downward, and the upper and lower traction ropes 8 move upward. Figure 7In the middle (c) state, in the natural state, under the rebound effect of the elastic ring 1, the left and right traction ropes 7 and the upper and lower traction ropes 8 are subjected to balanced upper and lower traction forces, so that the elastic ring 1 is in a perfect circle state.

[0052] It should be noted that whether the elastic ring 1 is in a perfect circular state in its natural state depends on the initial design shape of the elastic ring 1. If the initial state of the elastic ring 1 is designed as Figure 7 If the elastic ring 1 is initially designed to be in state (a), then rotating the rope wheel counterclockwise can gradually change the elastic ring 1 to state (b) to (c). Figure 7 If the state (c) is reached, the rope pulley is rotated clockwise to gradually change the elastic ring 1 from the state (b) to the state (a).

[0053] like Figure 4 In the embodiment, a transition shaft 25 and a transition pulley 26 are additionally provided for the output ends of the left and right traction ropes 7, and the output ends of the left and right traction ropes 7 are sleeved on the transition pulley 26 and then led out from the sleeve pipe head 12. Thus, the left and right traction ropes 7 and the upper and lower traction ropes 8 can be led outward along the approximately axial direction.

[0054] Regarding a driving structure of the rope pulley 15, as Figure 5 As shown, a through hole is provided at the axial center position of the rope wheel 15 and a spline groove is provided on the inner wall of the through hole, so as to form a spline shaft hole, and a spline shaft 17 is matchedly mounted on the inner side thereof, that is, the spline shaft 17 can move left and right in the spline hole.

[0055] A shell spline shaft hole 18 is provided on the inner wall of the handle shell, which can also match and fit the spline shaft 17 .

[0056] An extended shaft section 19 is fixed to the left end of the spline shaft 17 , and the outer end of the extended shaft section 19 is led out from the handle housing, and an adjusting hand wheel 20 is installed at the lead-out end.

[0057] A boss is provided between the shell spline shaft 17 and the extension shaft section 19, and a top spring 40 is provided between the boss and the inner wall of the handle shell, so that, in a natural state, the spline shaft 17 is pushed to move to the right by the top spring 40, so that the right end of the spline shaft 17 can be matched and inserted into the shell spline shaft hole 18. Since the shell spline shaft hole 18 is a fixed component, the spline shaft 17 cannot rotate at this time, so that the rope wheel 15 cannot rotate either, that is, the left and right traction ropes 7 and the upper and lower traction ropes 8 are fixed. When the hand wheel 20 is pulled outward, the spline shaft 17 can be linked to move outward, so that the right end of the spline shaft 17 is separated from the shell spline shaft hole 18. At this time, the hand wheel 20 and the rope wheel 15 are no longer locked, and the internal rope wheel 15 can be driven to rotate by rotating the hand wheel 20. The rotation of the rope wheel 15 can drive the left and right traction ropes 7 and the upper and lower traction ropes 8 to move up and down, thereby driving the elastic ring 1 to deform to meet the real-time use requirements.

[0058] Embodiment 2: Based on Embodiment 1, the same or different grinding components are further fixed on the outer sides of the support plates 9 on both sides, for example Fig. 9 As shown in the figure, a fixed spherical friction surface 22 is installed on the surface of the support plate 9 on one side, and a fixed plate friction surface 23 is installed on the surface of the support plate 9 on the other side to meet the use requirements of different parts.

[0059] Embodiment 3: Based on Embodiment 1, the ends of the left and right traction ropes 7 and the upper and lower traction ropes 8 are no longer connected to the rope wheels, but are respectively connected to the tension springs 27, such as Fig.12 The ends of the two tension springs 27 are respectively fixed on the inner wall of the handle housing. Thus, pulling down any traction rope or pushing up any traction rope can drive the corresponding traction hole and traction wheel to shrink inward or expand outward, and automatically reset after releasing the traction rope.

[0060] like Fig.12 In the embodiment, a horizontal vertical plate 32 can be provided in the inner cavity of the handle housing, and a vertical strip hole 28 is opened on the vertical plate 32, and a slider 29 is installed in the strip hole 28, so that the slider 29 can only slide vertically along the strip hole 28. Any traction rope is fixed to the slider 29, so that when the slider 29 is driven upward or downward to move, the corresponding traction rope can be driven to move upward or downward.

[0061] It can be seen that the present embodiment can realize the characteristic of real-time control of the deformation of the elastic ring 1. By holding the handle 14 and installing the slider 29 at the position corresponding to the thumb, during the grinding operation, the slider 29 is driven to move upward or downward, so as to flexibly control the deformation degree and deformation state of the elastic ring 1.

[0062] Embodiment 4: Based on Embodiment 1, the ends of the left and right traction ropes 7 and the upper and lower traction ropes 8 are no longer connected to the rope wheels, but are respectively connected to the tension springs 27, such as Fig.13 The ends of the two tension springs 27 are respectively fixed on the inner wall of the handle housing. Thus, pulling down any traction rope or pushing up any traction rope can drive the corresponding traction hole and traction wheel to shrink inward or expand outward, and automatically reset after releasing the traction rope.

[0063] like Fig.13 In the embodiment, a longitudinal vertical plate 32 can be provided in the inner cavity of the handle housing. After any traction rope is cut off, the two ends of the broken ends are respectively fixed to the two inner ends of the main swing rod 30 and the slave swing rod 31. The two outer ends of the main swing rod 30 and the slave swing rod 31 are hinged together through a pin 33, and a torsion spring 34 is installed on the outer side of the pin 33. The torsion spring 34 makes the main swing rod 30 and the slave swing rod 31 in a natural contraction state. The two inner ends of the main swing rod 30 and the slave swing rod 31 are also supported on the surface of the vertical plate 32, or the surface is set in the strip hole. A pressing handle 35 is fixed at the end of the active rod 30. By pressing the pressing handle 35 inwardly, the corresponding traction rope can be driven to move upward or downward. Therefore, this embodiment can realize the characteristic of real-time control of the deformation of the elastic ring 1. The pressing handle 35 is installed at the corresponding position of the index finger or thumb when holding the handle 14. During the grinding operation, the pressing handle 35 is pressed accordingly to flexibly control the deformation degree and deformation state of the elastic ring 1.

[0064] Embodiment 5: Another controllable deformation remover of dissolved matter in the eyeball, the main structure of which is the same as that in Embodiment 1 Figure 1 Similar, but the ground end of the cleaner is different.

[0065] The remover also includes a handle 14, an extension rod 13 and an elastic ring 1 which are fixedly connected in sequence from bottom to top. The grinding surface 2 is fixed on the outer ring of the elastic ring 1, and is used as a grinding component to directly grind the inner surface of the sclera.

[0066] like Fig.14 The specific structure inside the elastic ring 1 shown includes the elastic ring 1, a polished surface 2, a horizontal traction hole 3, a horizontal guide wheel 4, a vertical traction hole 5, a vertical guide wheel 6, left and right traction ropes 7, and upper and lower traction ropes 8, but does not include the support plate 9, the fixed shaft 10, the support wheel 11 and the sleeve joint 12.

[0067] It can be seen that the horizontal traction hole 3, the horizontal guide wheel 4, the vertical traction hole 5, and the vertical guide wheel 6 are respectively located on the inner wall of the elastic ring 1, wherein the horizontal traction hole 3 is located on the right side of the inner wall of the elastic ring 1, the horizontal guide wheel 4 is installed on the left side of the inner wall of the elastic ring 1, the vertical traction hole 5 is located on the lower side of the inner wall of the elastic ring 1, and the vertical guide wheel is installed on the upper side of the inner wall of the elastic ring 1. The horizontal guide wheel 4 and the vertical guide wheel 6 respectively include a wheel frame, an axle and a wheel, the wheel frame is fixed on the inner wall of the elastic ring 1, the axle is fixed on the wheel frame, the center hole of the wheel is installed on the axle, and the wheel is a V-shaped wheel.

[0068] Fig.14 It can be seen that a through hole is provided at the bottom of the elastic ring 1, and an inner support tube 36 is sleeved in the through hole. An outer sleeve 37 is sleeved on the outer side of the inner support tube 36. The outer sleeve 37 is located on the outer side of the elastic ring 1. An inner constraint pad 38 is also fixed on the inner support tube 36. The inner constraint pad 38 is located on the inner side of the elastic ring 1, so that the inner constraint pad 38 and the outer constraint sleeve 37 fix the inner support tube 36 in the through hole at the bottom of the elastic ring.

[0069] Fig.14 It can also be seen that a traction rope is connected to each traction hole and guide wheel. Specifically, the head ends of the left and right traction ropes 7 are fixed in the horizontal traction hole 3, the left and right traction ropes 7 are wrapped in the groove of the horizontal guide wheel 4, and the ends of the left and right traction ropes 7 are led out from the inner support tube 36. The head ends of the upper and lower traction ropes 8 are fixed in the vertical traction hole 5, the upper and lower traction ropes 8 are wrapped in the groove of the vertical guide wheel 6, and the ends of the upper and lower traction ropes 8 are led out from the inner support tube 36.

[0070] The ends of the left and right traction ropes 7 and the upper and lower traction ropes 8 can adopt any driving form of the above-mentioned embodiments to drive the left and right traction ropes 7 and the upper and lower traction ropes 8 to be pulled up and down respectively, that is, it can be achieved as follows Figure 7 The different states are shown.

[0071] Embodiment 6: Based on Embodiment 5, the elastic ring 1 is changed to an elastic balloon 39, and a friction layer is provided on the outer surface of the elastic balloon 39. At the same time, on the inner wall of the elastic balloon 39, pairs of traction holes (or traction wheels) are respectively provided in the left and right directions, the front and back directions, and the top and bottom directions. For example, in FIG17, inside the elastic balloon 39, the left and right inner walls are respectively fixed with the first traction hole A1 and the tail traction hole A2, the front and back inner walls are respectively fixed with the first traction hole B1 and the tail traction hole B2, and the top and bottom inner walls are respectively fixed with the first traction hole C1 and the tail traction hole C2. The head ends of the three traction ropes M1, M2 and M3 are respectively fixed to the corresponding head traction holes, and the three traction ropes M1, M2 and M3 are respectively looped around the corresponding tail traction holes, and the ends of the three traction ropes M1, M2 and M3 are respectively led out from the inner support tube 36. The lead-out end of each traction rope can adopt any control mechanism of the above embodiments, for example, a tension spring 27 is fixedly connected to the end of each traction rope, a slider 29 is fixed on each traction rope, and three vertical slide grooves are respectively arranged on the handle shell, and each slider is matched and fitted in the corresponding slide groove. Thus, driving any slider upward or downward to move can drive the corresponding traction rope to move in a telescopic manner, and the elastic balloon can be deformed in the corresponding direction.

[0072] It should be noted that when the elastic balloon 39 is deformed in any dimensional direction (left-right, front-back, up-down) or in two or three dimensional directions at the same time, the remaining traction ropes can also cooperate with the deformation under the action of the tension spring.

[0073] This embodiment uses a deformed spherical friction layer, which can achieve different degrees of convex deformation, thereby meeting more scleral inner surface cleaning needs.

[0074] Embodiment 7: Based on Embodiment 6, in order to realize the individual and simultaneous control of one, two or three of the three sliders, a driving sleeve 42 is also provided on the upper end of the handle, such as Fig.18 As shown, the drive sleeve can be matched and sleeved on the upper end of the handle and can slide axially. The inner end of the drive sleeve is sleeved on the upper end of the handle with a tension spring or a top spring, so that the drive sleeve can automatically reset after axial movement.

[0075] like Fig.19 As shown, there is an inner ring platform 43 protruding inward on the inner wall of the driving sleeve, and two grooves 44 are arranged on the inner ring platform 43 in parallel along the axial direction. The width of the two grooves 44 is slightly larger than the width of the slider 29, and the spacing between the two grooves 44 is adapted to the spacing between two adjacent sliders.

[0076] An annular boss 45 is provided on the outside of the handle, and a top spring 46 is installed between the inner annular boss 43 and the annular boss 45. Therefore, when the driving sleeve 42 is pushed downward, the lower edge of the inner annular boss 43 can be supported on the upper side of at least one of the sliders 29, and the slider is pressed to move downward along the slide groove 28.

[0077] When the driving sleeve is pushed downward (or pushed upward), one, two or three sliders can be driven to move downward (or upward) through the inner ring. When one groove corresponds to one slider, the driving sleeve can drive the two sliders to move at the same time. When two grooves correspond to two sliders, the driving sleeve can only drive one slider to move. When no groove corresponds to a slider, the driving sleeve can drive the three sliders to move together at the same time.

[0078] To facilitate the rotation and sliding of the drive sleeve, an annular sleeve 47 is sleeved on its outer side. The outer circumference of the annular sleeve 47 has an inwardly recessed annular groove 48. Interlayers 49 are spaced apart in the annular groove. A recessed area is formed between adjacent interlayers 49, which is suitable for the thumb or index finger to facilitate the rotation of the drive sleeve.

[0079] Therefore, this embodiment can more conveniently and flexibly control any one, two or three of the three traction ropes. It only needs to rotate the drive sleeve to the corresponding position of the corresponding mark, and push the drive sleeve downward or upward to move, which can improve the convenience of use.

[0080] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. For example, it is not excluded that the horizontal guide wheel 4 and the vertical guide wheel 6 are replaced by traction holes based on Example 1.
