Description

Technical Field

[0001] This invention relates to the field of ophthalmic surgery technology, specifically to an ophthalmic full-angle scleral depressor. Background Technology

[0002] The eyeball consists of the eyeball wall and the contents of the eye. The structure of the eyeball wall, from the outside to the inside, consists of the fibrous membrane, the uvea, and the retina. The fibrous membrane is composed of the porcelain-white sclera and the transparent cornea. The contents of the eye include three substances: the vitreous body, the lens, and the aqueous humor. The transparent gel-like vitreous body accounts for 4 / 5 of the volume of the eyeball.

[0003] In cases of certain eye diseases, such as retinal detachment, vitreous hemorrhage, or infectious endophthalmitis, vitrectomy is necessary.

[0004] Due to the complex structure of the eyeball and the limited surgical field of vision, when removing peripheral vitreous humor, the sclera must be pressed against the outside of the eyeball so that the surgeon can clearly see the fundus structure and perform appropriate treatment on the vitreous humor and retina.

[0005] However, during surgery, the surgeon needs to hold the light guide in one hand and the vitrectomy tip or other instruments in the other, so the scleral depressor must be operated by an assistant. When the assistant lacks experience, it can easily affect the surgeon's efficiency, and in severe cases, may even lead to the surgeon accidentally cutting the retina, causing damage to the patient. Furthermore, if the scleral depressor is not applied properly or is unstable, it can easily lead to damage to the retina and other tissues, or complications such as bleeding, and even cause severe visual impairment. Although using various wide-angle viewing systems can avoid some pressure application, external scleral depressor is still necessary when comprehensively treating the peripheral vitreous body.

[0006] In other words, existing scleral depressors can only apply pressure from a single direction, which has the following shortcomings when performing ophthalmic surgery:

[0007] 1. During the surgery, the surgeon needs to hold the light guide in one hand and the vitrectomy head or other instruments in the other. Therefore, the surgeon cannot perform the compression and resection operations at the same time. The compression device needs to be operated by the assistant. This not only requires a high degree of cooperation between the assistant and the surgeon, but also if the assistant is not experienced enough, it can easily affect the surgeon's surgical efficiency. In severe cases, it may even lead to the surgeon accidentally cutting the retina and causing damage to the patient.

[0008] 2. Existing scleral indenters can only apply pressure to the eyeball in one direction. During surgery, the positions of the surgeon and the patient are relatively fixed. This makes it difficult to apply pressure to other parts of the eyeball, as the surrounding orbital tissues can interfere with the pressure. In other words, it is not convenient to apply pressure to different angles of the eyeball. If the scleral indentation is insufficient or unstable, it can easily lead to damage to the retina and other tissues, or complications such as bleeding, and even cause serious visual impairment. Although various wide-angle observation systems can avoid some pressure issues, external scleral indentation is still necessary when dealing with the peripheral vitreous body comprehensively.

[0009] Therefore, there is an urgent need for a scleral depressor that can be operated by one person and can apply pressure at all angles. Summary of the Invention

[0010] The purpose of this invention is to provide an ophthalmic full-angle scleral depressor in order to solve the problems existing in the prior art.

[0011] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0012] An ophthalmic full-angle scleral depressor includes a finger sleeve body that can be worn on a finger. A rotating mechanism and a first fixing part are sequentially arranged on the upper part of the finger sleeve body. A non-rotatable depressor rod is arranged on the top of the first fixing part. The non-rotatable depressor rod is arranged in the same direction as the finger sleeve body.

[0013] The rotating mechanism includes a rotatable top pressure rod, which can rotate a certain angle relative to the finger sleeve body and the first fixing part with the rotating mechanism, and a certain angle is formed between the rotatable top pressure rod and the non-rotatable top pressure rod;

[0014] During operation, the rotatable or non-rotatable pressure rod can be selected to apply pressure according to the desired position of the eyeball. When applying pressure to the left or right side of the eyeball, the non-rotatable pressure rod can be used. When applying pressure to the upper or lower side of the eyeball, the angle of pressure can be adjusted by rotating the rotatable pressure rod relative to the first fixing part and the finger sleeve body to avoid touching the surrounding tissues of the eye socket.

[0015] As an improvement to the technical solution of the ophthalmic full-angle scleral pressure device of the present invention, the rotating mechanism includes a hollow second fixing part and a fixing shaft. The fixing shaft is disposed in the middle of the second fixing part, and the upper and lower end faces of the second fixing part and the fixing shaft are respectively fixedly connected to the first fixing part and the finger sleeve body.

[0016] A first rotating component is sleeved on the fixed shaft. The outer periphery of the first rotating component is provided with a first tooth. A second rotating component is sleeved on the outside of the first rotating component. A through hole is opened in the middle of the second rotating component. The wall of the through hole is provided with a second tooth that meshes with the first tooth.

[0017] The outer side of the second rotating component is connected to the rotatable top pressure rod, and a sliding groove is provided along the circumference of the second fixed part. The rotatable top pressure rod passes through the sliding groove, and the rotatable top pressure rod can slide along the length direction of the sliding groove.

[0018] As an improvement to the technical solution of the ophthalmic full-angle scleral pressure device of the present invention, the outer periphery of the second rotating component is provided with an inner groove, and the inner periphery of the second fixed part is also provided with a plurality of outer grooves, the height of each outer groove being greater than the height of the sliding groove.

[0019] The rotatable pressure rod includes a pressure end for pressing the eyeball and a connecting end for connecting with the second rotating component. The connecting end is provided with a limit block, which can be respectively inserted into the inner groove or the outer groove. A spring is also provided between the limit block and the inner groove.

[0020] During operation, the rotatable top pressure rod is engaged with different outer slots through the limiting holes, so that it is positioned at the corresponding position during the sliding process.

[0021] As an improvement to the technical solution of the ophthalmic full-angle scleral pressor of the present invention, the inner circumference of the second fixing part is provided with four outer grooves, which are respectively 0° groove, 30° groove, 150° groove and 180° groove.

[0022] As an improvement to the technical solution of the ophthalmic full-angle scleral depressor of the present invention, the size and shape of the limiting block are consistent with the size and shape of the outer groove; the width and height of the limiting block are consistent with the width and height of the inner groove.

[0023] As an improvement to the technical solution of the ophthalmic full-angle scleral pressure device of the present invention, the pressure end of the rotatable pressure rod and / or the non-rotatable pressure rod is provided with multiple protrusions, each of which is a semi-circular soft protrusion.

[0024] As an improvement to the technical solution of the ophthalmic full-angle scleral pressor of the present invention, the length of the rotatable pressor rod is greater than the length of the non-rotatable pressor rod, and the rotatable pressor rod is a curved rod that bends outward.

[0025] As an improvement to the technical solution of the ophthalmic full-angle scleral pressure device of the present invention, the finger sleeve body includes a sleeve-shaped part, and the edge of the finger sleeve body has an adjustment position arranged along the length direction of the finger sleeve body.

[0026] As an improvement to the technical solution of the ophthalmic full-angle scleral pressure device of the present invention, the certain angle is 90°.

[0027] The beneficial effects of this invention are:

[0028] 1. In this invention, because a finger sleeve body is provided, when in use, the finger sleeve body can be put on the main surgeon's fingers, enabling one person to perform pressing and operation simultaneously.

[0029] 2. Since a rotating mechanism and a first fixing part are provided on the upper part of the finger sleeve body, and a non-rotatable pressing rod is provided on the upper part of the first fixing part, the non-rotatable pressing rod is arranged in the same direction as the finger sleeve body, and the left or right side of the eyeball can be pressed by the non-rotatable pressing rod.

[0030] In addition, since the rotatable pressure rod can rotate relative to the first fixed part and the finger sleeve body, the angle of its pressure direction can be adjusted by rotating the rotatable pressure rod to apply pressure, so as to avoid touching the tissue around the eye socket; at the same time, since a certain angle is formed between the rotatable pressure rod and the non-rotatable pressure rod, the pressure direction of the rotatable pressure rod and the non-rotatable pressure rod are not the same, that is, the rotatable pressure rod and the finger sleeve body are set in different directions, and the upper or lower side of the eyeball can be pressed by the rotatable pressure rod;

[0031] In this way, the combined action of the rotatable and non-rotatable pressure rods achieves the effect of pressing the eyeball at different positions, that is, achieving the effect of full-angle pressure, thus solving the problems existing in the prior art. Attached Figure Description

Detailed Implementation

[0042] To make the objectives, technical solutions, and beneficial effects of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments.

[0043] like Figures 1 to 7 As shown, the ophthalmic full-angle scleral depressor includes a finger sleeve body 1 that can be worn on a finger. A rotating mechanism 2 and a first fixing part 3 are sequentially arranged on the upper part of the finger sleeve body 1. A non-rotatable depressor rod 6 is arranged on the top of the first fixing part 3. The non-rotatable depressor rod 6 is arranged in the same direction as the finger sleeve body 1.

[0044] The rotating mechanism 2 includes a rotatable pressing rod 5. The rotatable pressing rod 5 can rotate a certain angle relative to the finger sleeve body 1 and the first fixed part 3 with the rotating mechanism 2, and a certain angle is formed between the rotatable pressing rod 5 and the non-rotatable pressing rod 6.

[0045] During operation, the rotatable pressing rod 5 and the non-rotatable pressing rod 6 can be selected to press the eyeball 23 according to the desired position. When pressing the left or right side of the eyeball 23, the non-rotatable pressing rod 6 can be used. When pressing the upper or lower side of the eyeball 23, the pressing direction angle can be adjusted by rotating the rotatable pressing rod 5 relative to the first fixing part 3 and the finger sleeve body 1 to avoid touching the surrounding tissue of the eye socket.

[0046] In detail, such as Figure 1 As shown, where Figure 1 Including Figure 1 a, Figure 1 b and Figure 1 As shown in c, the ophthalmic full-angle scleral depressor includes a finger sleeve body 1. Because of the finger sleeve body 1, it can be put on the surgeon's finger during use, enabling one surgeon to perform depressing and operation at the same time.

[0047] Furthermore, since a rotating mechanism 2 and a first fixing part 3 are provided on the upper part of the finger sleeve body 1, and a non-rotatable pressing rod 6 is provided on the upper part of the first fixing part 3, the non-rotatable pressing rod 6 is arranged in the same direction as the finger sleeve body 1, and the left or right side of the eyeball 23 can be pressed by the non-rotatable pressing rod 6.

[0048] In addition, since the rotatable pressing rod 5 can rotate relative to the first fixed part 3 and the finger sleeve body 1, the pressing direction angle can be adjusted by rotating the rotatable pressing rod 5 to press down and avoid touching the periorbital tissue. At the same time, since a certain angle is formed between the rotatable pressing rod 5 and the non-rotatable pressing rod 6, the pressing direction of the rotatable pressing rod 5 and the non-rotatable pressing rod 6 is not the same, that is, the rotatable pressing rod 5 and the finger sleeve body 1 are set in different directions, and the upper or lower side of the eyeball 23 can be pressed by the rotatable pressing rod 5.

[0049] In this way, the combined action of the rotatable pressing rod 5 and the non-rotatable pressing rod 6 achieves the effect of pressing the eyeball 23 at different positions, that is, the effect of pressing at all angles is achieved, thus solving the problems existing in the prior art.

[0050] In some embodiments of the present invention, the rotating mechanism 2 includes a hollow second fixing part 6 and a fixing shaft 7. The fixing shaft 7 is disposed in the middle of the second fixing part 6, and the upper end face and lower end face of the second fixing part 6 and the fixing shaft 7 are respectively fixedly connected to the first fixing part 3 and the finger sleeve body 1.

[0051] A first rotating component 8 is sleeved on the fixed shaft 7. A first tooth 10 is provided on the outer periphery of the first rotating component 8. A second rotating component 9 is sleeved on the outside of the first rotating component 8. A through hole is opened in the middle of the second rotating component 9. A second tooth 11 that meshes with the first tooth 10 is provided on the wall of the through hole.

[0052] The outer side of the second rotating component 9 is connected to the rotatable top pressure rod 5, and a sliding groove 12 is provided along the circumference of the second fixed part 6. The rotatable top pressure rod 5 passes through the sliding groove 12, and the rotatable top pressure rod 5 can slide along the length direction of the sliding groove 12.

[0053] In detail, the rotating mechanism 2 in this invention is mainly used to set the rotatable top pressure rod 5 and realize the rotation of the rotatable top pressure rod 5 relative to the first fixed part 3 and the finger sleeve. By rotating the rotatable top pressure rod 5, the effect of adjusting the top pressure angle is achieved.

[0054] As an embodiment of the present invention, the rotating mechanism 2 includes a hollow second fixing part 6 and a fixing shaft 7. The fixing shaft 7 is disposed in the middle of the second fixing part 6. The upper end face and the lower end face of the second fixing part 6 and the fixing shaft 7 are respectively fixedly connected to the first fixing part 3 and the finger sleeve body 1, thereby realizing the connection between the first fixing part 3 and the finger sleeve body 1 through the second fixing part 6 and the fixing shaft 7.

[0055] Furthermore, since the first rotating component 8 is sleeved on the fixed shaft 7, the first rotating component 8 can rotate relative to the fixed shaft 7. At the same time, since the first rotating component 8 is provided with a first tooth 10 on its outer side and the second transmission component is provided with a second tooth 11 on its inner side, the first tooth 10 and the second tooth 11 mesh with each other. Through the mutual meshing of the first tooth 10 and the second tooth 11, the effect of the second rotating component 9 rotating relative to the first rotating component 8 is achieved.

[0056] Furthermore, a rotatable pressing rod 5 is provided on the outer side of the second rotating component 9. When the second rotating component 9 rotates, the rotatable pressing rod 5 rotates with it. Moreover, the rotatable pressing rod 5 passes through the sliding groove 12 provided on the outer side of the second fixed part 6. When the rotatable pressing rod 5 is pushed or moved, it drives the second rotating component 9. Under the combined action of the meshing first tooth 10 and second tooth 11, it achieves the effect of sliding within the sliding groove 12. Since the finger sleeve body 1 is worn on the finger, it does not rotate. Therefore, the rotatable pressing rod 5 can slide in the sliding groove 12 to achieve the effect of rotating relative to the finger sleeve body 1, thereby adjusting the angle and achieving the effect of pressing at all angles.

[0057] Furthermore, the outer periphery of the second rotating component 9 is provided with an inner groove 14, and the outer periphery of the second fixing part 6 is also provided with a plurality of outer grooves 15, the height of the plurality of outer grooves 15 being greater than the height of the sliding groove 12.

[0058] The rotatable top pressure rod 5 includes a top pressure end for pressing the eyeball 23 and a connecting end for connecting with the second rotating component 9. The connecting section is provided with a limit block 13, which can be respectively inserted into the inner groove 14 or the outer groove 15. A spring 16 is also provided between the limit block 13 and the inner groove 14.

[0059] During operation, the rotatable top pressure rod 5 is inserted into different outer slots 15 through the limiting holes so that it is positioned in the corresponding position during the sliding process.

[0060] Since the rotatable top pressure rod 5 can slide along the sliding groove 12, achieving the positioning effect of the rotatable top pressure rod 5, and allowing the positioning effect to be set according to actual operational needs, is one of the important improvements of this invention. Specifically, by opening an inner groove 14 on the outer periphery of the second rotating component 9, and providing a plurality of outer grooves 15 on the inner periphery of the second fixing part 6, wherein the height of each outer groove 15 is greater than the height of the sliding groove 12.

[0061] Furthermore, the rotatable pressing rod 5 includes a pressing end for pressing the eyeball 23 and a connecting end for connecting with the second rotating component 9. A limiting block 13 is provided at the connecting end. The limiting block 13 can be inserted into the inner groove 14 or the outer groove 15 respectively, and a spring 16 is also provided between the limiting block 13 and the inner groove 14.

[0062] In use, the limiting block 13 at the connecting end of the rotatable top pressure rod 5 is engaged in one of the outer slots 15. When the rotatable top pressure rod 5 is pressed from the outside in, the rotatable top pressure rod 5 moves towards the inner slot 14, and the spring 16 is deformed by the pressure. At this time, the limiting block 13 leaves the outer slot 15 and is engaged in the slot along with the rotatable top pressure rod 5. Then, by pushing or flicking the rotatable top pressure rod 5 to slide in the sliding groove 12, the rotatable top pressure rod 5 drives the limiting member and the second rotating member 9 to rotate relative to the first rotating member 8. When rotating to the next outer slot 15, the rotatable top pressure rod 5 is released, that is, the force A of pressing the rotatable top pressure rod 5 is removed, and the spring 16 returns to its original position. At this time, under the action of the spring 16, the limiting member leaves the inner slot 14 and is engaged in the outer slot 15, thus completing the movement and positioning effect between different outer slots 15.

[0063] Preferably, the size and shape of the limiting block 13 are consistent with the size and shape of the outer groove 15; the width and height of the limiting block 13 are consistent with the width and height of the inner groove 14. This allows the limiting block 13 to be better engaged in the outer groove 15 or the inner groove 14, preventing the limiting block 13 from disengaging from the outer groove 15 or the inner groove 14 when it is not rotating.

[0064] In this invention, the inner periphery of the second fixing part 6 is provided with four outer slots 15, which are respectively 0° slot 17, 30° slot 1817, 150° slot 1917 and 180° slot 2017.

[0065] In this invention, the angles of the four outer slots 15 are not arbitrarily determined. Specifically, during use, the finger sleeve body 1 is placed on the finger, with the 0° slot 17 and 180° slot 2017 forming 90° angles with the front and back of the finger, respectively; that is, relative to the front and back of the finger, the 0° slot 17 and 180° slot 2017 are located on the left and right sides of the finger. When the rotatable pressure rod 5 is positioned at the 0° slot 17 or 180° slot 2017, it facilitates the main blade pressing down on the eyeball 23 via the rotatable pressure rod 5.

[0066] The 30° slot 1817 and the 150° slot 1917 are located between the 0° slot 17 and the 180° slot 2017. As an embodiment of the present invention, the 0° slot 17, the 30° slot 1817, the 150° slot 1917 and the 180° slot 2017 are arranged counterclockwise.

[0067] Since the rotatable pressure rod 5 can press on the upper or lower side of the eyeball 23, it can avoid the surrounding tissue of the eye socket; and since the non-rotatable pressure rod 6 is set in the same direction as the finger sleeve body 1, it can press on the left or right side of the eyeball 23.

[0068] However, since devices such as non-contact wide-angle lenses are also used during surgery, when the non-rotatable pressure rod 6 is used for pressure, if the rotatable pressure rod 5 is in the 0° slot 17 or the 180° slot 2017, it is easy for the rotatable pressure rod 5 to come into contact with, touch, or block the non-contact wide-angle lens. Therefore, in this invention, by rotating the rotatable pressure rod 5 in conjunction with the rotating mechanism 2 and positioning it in the 30° slot 1817 or the 150° slot 1917, the rotatable pressure rod 5 can be flipped upwards to avoid devices such as the non-contact wide-angle lens.

[0069] In some embodiments of the present invention, the pressing ends of the rotatable pressing rod 5 and / or the non-rotatable pressing rod 6 are provided with a plurality of protrusions 21. Each protrusion 21 is a semi-circular soft protrusion 21. Under the action of the protrusions 21, damage to the eyeball 23 can be avoided when pressing.

[0070] Preferably, the rotatable pressing rod 5 and / or the non-rotatable pressing rod 6 are provided with four protrusions 21 at their pressing ends. The four protrusions 21 form a rectangle. Since the four protrusions 21 are all semi-circular, it can not only avoid damage to the eyeball 23 when pressing, but also avoid the pressing end from sliding relative to the eyeball 23 when pressing.

[0071] In some embodiments of the present invention, the length of the rotatable top pressure rod 5 is greater than the length of the non-rotatable top pressure rod 6, and the rotatable top pressure rod 5 is a curved rod that bends outward. Preferably, the angle is 90°.

[0072] In detail, since the non-rotatable pressure rod 6 is arranged in the same direction as the finger sleeve body 1, it is used to press down on the left or right side of the eyeball 23; while the rotatable pressure rod 5 is used to press down on the upper and lower sides of the eyeball 23, and the two pressure positions on the eyeball 23 form 90° respectively. Therefore, when the finger sleeve body 1 is put on the finger, the rotatable pressure rod 5 can easily press down on the eyeball 23, and the curved rotatable pressure rod 5 can press down on the eyeball 23 along the direction of the eye socket.

[0073] Since the length of the rotatable top pressure rod 5 is greater than the length of the non-rotatable top pressure rod 6, in this invention, the rotatable top pressure rod 5 can be a rotatable long top pressure rod, and the non-rotatable top pressure rod 6 can be a non-rotatable short top pressure rod.

[0074] In some embodiments of the present invention, the finger sleeve body 1 includes a sleeve-shaped part, and the edge of the finger sleeve body 1 is provided with an adjustment position 22 arranged along the length direction of the finger sleeve body 1. Under the action of the adjustment position 22, the present invention can be put on different fingers of different people, and the finger to be put on can be selected as needed.

[0075] As an embodiment of the present invention, the adjustment position 22 and the sliding groove 12 are respectively arranged on opposite sides of the finger sleeve body 1. When the finger sleeve body 1 is put on the finger, the adjustment position 22 on the finger sleeve body 1 is placed in front of the finger, while the sliding groove 12 for the sliding of the rotatable top pressure rod 5 is placed behind the finger. In this way, when the finger sleeve body 1 is put on the finger, it will not affect the sliding or rotation of the rotatable top pressure rod 5.

[0076] The following is combined Figures 1 to 7 The following describes how the invention is used, taking the example of fitting the invention to the surgeon's left hand and performing surgery on the patient's left eye.

[0077] First, from Figure 1 , Figure 3 and Figure 4As can be seen from the above, the present invention includes a finger sleeve body 1, a rotating mechanism 2, and a first fixing part 3. The rotating mechanism 2 is disposed between the finger sleeve body 1 and the first fixing part 3, and a non-rotatable pressing rod 6 is provided on the upper part of the first fixing part 3. The rotatable pressing rod 5 passes through the sliding groove 12 and is connected to the second rotating component 9. The detailed structure is as described above and will not be repeated here.

[0078] When using this invention, the finger sleeve body 1 is worn on the left hand, and surgery is performed on the patient's left eye. At this time, the left, right, upper and lower sides of the eyeball 23 correspond to the lateral rectus muscle quadrant region, medial rectus muscle quadrant region, inferior rectus muscle quadrant region and superior rectus muscle quadrant region of the eyeball 23.

[0079] like Figure 2 As shown, Figure 2 Including Figure 2 a, Figure 2 b and Figure 2 c, Figure 2 A schematic diagram of the front view of the rotatable pressing rod 5 of the present invention when pressing the eyeball 23 is shown. In fact, in the present invention, both the rotatable pressing rod 5 and the non-rotatable pressing rod 6 are pressed by the pressing end, and the setting direction of the pressing end is tangent to the eyeball 23. This makes it easier for the pressing end to contact the eyeball 23 better and achieve a better pressing effect.

[0080] like Figure 5 As shown, Figure 5 This is a schematic diagram illustrating the rotation principle of the rotatable top pressure rod 5. Figure 5 a is a schematic diagram of the initial position. Figure 5 b and Figure 5 c represents a force diagram illustrating the rotation of a rotatable long top compression rod. Figure 5 d is a schematic diagram of the rotatable long top pressure rod in the state of having rotated to the next slot position.

[0081] In detail, combined Figure 5 As can be seen, the example of rotating from 0° slot 17 to 30° slot 1817 is used for illustration.

[0082] like Figure 5 As shown in a, in the initial position, the limiting block 13 is engaged in the 0° slot 17;

[0083] When the rotatable top pressure rod 5 rotates, as Figure 5As shown in b, by applying a force A to the rotatable top pressing rod 5, the rotatable top pressing rod 5 is pressed, causing the limiting block 13 to leave the 0° slot 17 and be inserted into the inner slot 14. Then, a force B is applied to the rotatable top pressing rod 5 to push it to the next slot, pushing or moving the rotatable top pressing rod 5 to the 30° slot 1817, causing the rotatable top pressing rod 5 to drive the second rotating component 9 to rotate relative to the first rotating component 8. At this time, the rotatable top pressing rod 5 slides in the sliding slot 12, achieving the effect of movement.

[0084] like Figure 5 As shown in c, when the rotatable top pressure rod 5 rotates to the 30° groove 1817, the rotatable top pressure rod 5 is released, that is, the force A of pressing the rotatable top pressure rod 5 is removed. At this time, the spring 16 returns to its original state under the action of the spring force C, and the limiting member leaves the inner groove 14.

[0085] like Figure 5 As shown in d, when the limiting member leaves the inner groove 14, the rotatable top pressure rod 5, under the action of the spring 16, is inserted into the 30° groove 1817, thus completing the movement and positioning effect between different outer grooves 15.

[0086] like Figure 6 and Figure 7 As shown, Figure 6 The diagram shows the rotatable top pressure rod 5 in the 0° slot 17, 30° slot 1817, 150° slot 1917 and 180° slot 2017 respectively when the present invention is worn on the fingers of the left hand; Figure 7 The diagram illustrates the invention, which is worn on the fingers of the right hand, with the rotatable top pressure rod 5 positioned in the 30° slot 1817 and the 150° slot 1917 respectively. Figure 6 and Figure 7 It can be seen that during surgery, the non-contact wide-angle lens can easily touch and affect the eyeball 23. Therefore, when the non-rotatable pressure rod 6 is used to press on the eyeball 23, the rotatable pressure rod 5 can be placed in the 30° slot 1817 or the 150° slot 1917 to achieve the effect of the rotatable pressure rod 5 flipping upwards and avoiding contact with the non-contact wide-angle lens.

[0087] 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.
