Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to an eyelid retractor for treating ophthalmic conditions. Background Technology

[0002] An eyelid retractor is a tool used in ophthalmic surgery and examinations, primarily to separate the eyelids, providing a clearer field of vision and ensuring precise manipulation by the surgeon. It plays a crucial role in ophthalmic treatment, reducing patient discomfort and improving surgical efficiency. With continuous technological advancements, the design of eyelid retractors is constantly being optimized, and future models may place even greater emphasis on comfort, precision, and patient experience, becoming an indispensable auxiliary tool in ophthalmic diagnosis and treatment.

[0003] Existing technologies also disclose some eyelid retractors, such as the Chinese patent announcement number CN111743587B, which discloses an eyelid retractor. This device integrates tools for retracting the eyelid and for locating ocular surface structures into one device, which makes the operation of retracting the eyelid and locating ocular surface structures more convenient and improves the positioning accuracy, effectively ensuring the consistency of experimental or treatment models.

[0004] While the device can perform detection functions, it cannot support and stabilize the retractor, which may limit the field of vision, affect the surgeon's operational precision, and increase the difficulty and risk of the surgery. Eyelid instability may cause patient discomfort, increase anxiety or pain, and affect their cooperation. It may also prolong the operation time and increase anesthesia and surgical risks. More seriously, the inability to stabilize the eyelid may lead to accidental injury to the eyeball or other ocular tissues by the instruments, increasing the risk of postoperative complications. Summary of the Invention

[0037] By setting up lateral and vertical adjustment components to adjust the position of the eyelid support component, the opening and angle of the eyelid can be flexibly adjusted to meet the needs of different patients and the treatment of ophthalmic diseases. This not only provides doctors with the best operating field of vision and improves the accuracy of surgery, but also reduces patient discomfort and enhances cooperation.

[0038] By setting an angle fixing component to adjust and fix the angle of the first support frame, the angle of the support frame can be flexibly adjusted according to the patient's eye characteristics and condition needs, providing personalized treatment and ensuring that the eyelids open at the most suitable angle, thereby improving the accuracy of treatment;

[0039] By setting limit components and connecting components, the first support frame and the mobile frame can be quickly disassembled and assembled, and the equipment can be completely disassembled. After disassembly, each part of the equipment can be cleaned and inspected independently, reducing the risk of cross-infection and ensuring the hygiene of the equipment. Regular maintenance and cleaning are more convenient, which helps to extend the service life of the equipment. At the same time, the disassembled components are smaller in size, making them easier to carry and store. For medical institutions that need multiple pieces of equipment, the disassembled design makes it easier to transport and manage the equipment.

[0040] By setting up a first support frame, a movable frame, and a locking assembly to work together to support and fix the support rod, and simultaneously supporting the patient's head with the support rod, the stability and support of the eyelid retractor can be significantly enhanced, ensuring that the device remains stable during surgery, reducing operational errors. The fixation of the patient's head with the support rod can effectively reduce the patient's involuntary head movement, helping the doctor to focus on the operation and improve precision. Moreover, the patient can maintain a comfortable and relaxed posture during treatment, reducing movements caused by discomfort. Attached Figure Description

[0067] like Figures 1 to 12 As shown, an embodiment of the present invention provides an eyelid retractor for treating ophthalmic diseases, comprising:

[0068] First support frame 1;

[0069] A fixing component is provided on the inner side wall of the bottom of the first support frame 1 for quick fixing of the first support frame 1;

[0070] Limiting sleeve 2 is disposed on the outer wall of the fixing component;

[0071] The second slot 26 is evenly opened on the inner side wall of the limiting sleeve 2;

[0072] An angle fixing component is installed inside the limiting sleeve 2, and is used to adjust and fix the angle between the fixing component and the first support frame 1;

[0073] A limiting component is disposed at the top end of the first support frame 1;

[0074] The movable frame 3 is located outside the first support frame 1;

[0075] The connecting components are symmetrically arranged at both ends of the movable frame 3, and the first support frame 1 and the movable frame 3 are connected and fixed by the limiting components;

[0076] The engaging assembly is located at both ends of the movable frame 3 and on the bottom side of the opposite end of the first support frame 1 on both sides;

[0077] The limiting post 4 is located inside the engaging assembly and is connected to the engaging assembly through two symmetrically opened limiting grooves 41 on the outer side of the limiting post 4, thereby supporting and fixing the limiting post 4.

[0078] Support rod 42 is fixed to the bottom end of limiting post 4 and is used to support and limit the patient's head.

[0079] Slide rail 5 is fixed to the middle section side wall of the movable frame 3;

[0080] The lateral movement component is located on the outside of the slide rail 5, and the slide rail 5 supports the lateral movement component.

[0081] The sliding sleeve 54 is located on the outside of the moving end of the transverse component, and the transverse component enables the sliding sleeve 54 to move laterally along the slide rail 5.

[0082] The lifting assembly is located inside the sliding sleeve 54;

[0083] Fixing bolt 68 is installed on the bottom lifting end of the lifting assembly;

[0084] The second fixing frame 6 is set on the outside of the bottom lifting end of the lifting assembly, and the lifting end is connected and fixed to the second fixing frame 6 by fixing bolts 68;

[0085] An eyelid support assembly, located on the bottom side wall of the second fixation frame 6, is used to support the patient's eyelids.

[0086] The fixing assembly includes a fixing frame 11 fixed to the outer wall of the opposite side of the bottom end of the first support frame 1 on both sides. The fixing frame 11 is supported and fixed by the first support frame 1. The inner side of the bottom wall of the fixing frame 11 is threaded with a first lead screw 12. The fixing frame 11 supports and limits the first lead screw 12. By rotating the bottom end of the first lead screw 12, the first lead screw 12 can be moved to the top as a whole. The top of the first lead screw 12 is fixedly connected to a top plate 13. The top plate 13 is supported and fixed by the first lead screw 12. Thus, the equipment can be fixed by the cooperation between the top plate 13 and the fixing frame 11.

[0087] The angle fixing assembly includes a transmission column 24 slidably connected to the inner side of the limiting sleeve 2, which supports and limits the transmission column 24. A first sliding rod 25 is fixedly connected to the bottom wall of the transmission column 24 and slides against the inner wall of the bottom end of the first support frame 1. The first support frame 1 and the first sliding rod 25 cooperate to limit the angle between the first support frame 1 and the transmission column 24, ensuring that the transmission column 24 can only move laterally with the first support frame 1 and cannot rotate. A limiting ring 21 is fixedly connected to the outer wall of the middle section of the transmission column 24 and slides against the inner wall of the limiting sleeve 2, supporting and fixing the limiting ring 21. A spring 22 is fixedly connected to the outer wall of the limiting ring 21 on the side away from the first sliding rod 25. The end of the spring 22 on the side away from the limiting ring 21 is fixedly connected to the inner wall of the limiting sleeve 2. 2. The inner wall of the limiting sleeve 2 is the stress point, which pushes the limiting ring 21 away from the first support frame 1. At the same time, the limiting ring 21 drives the transmission column 24 to move outward. Two locking rods 23 are symmetrically fixed to the outer wall of the limiting ring 21 away from the spring 22. The locking rods 23 are engaged with the second locking groove 26. The locking rods 23 and the second locking groove 26 engage with each other, thereby locking and fixing the angle between the transmission column 24 and the limiting sleeve 2. By pressing the transmission column 24 towards the fixed frame 11, the transmission column 24 drives the limiting ring 21 and the locking rods 23 to move towards the fixed frame 11, thereby canceling the engagement between the locking rods 23 and the second locking groove 26. This allows the transmission column 24 and the limiting ring 21 to rotate inside the limiting sleeve 2, thereby adjusting the angle between the limiting sleeve 2 and the transmission column 24.

[0088] The limiting component includes a first slot 15 formed on the top wall of the first support frame 1 on both sides, and a fixing plate 36 fixedly connected to the top wall of the first support frame 1. A second chuck 37 is rotatably connected to the inner side of the bottom of the fixing plate 36. The second chuck 37 is rotatably connected to the first slot 15. The first slot 15 supports and limits the second chuck 37, allowing the second chuck 37 to rotate inside the first slot 15.

[0089] The connecting assembly includes insert plates 31 fixedly connected to the outer walls of both ends of the movable frame 3. The movable frame 3 simultaneously supports and fixes the insert plates 31 on both sides. A first chuck 32 is rotatably connected to the top middle section of the insert plate 31. The insert plates 31 support and limit the first chuck 32, allowing it to rotate on the top of the insert plates 31. A first handle 33 is fixedly connected to the top wall of the first chuck 32. The first chuck 32 is rotatably connected to the first slot 15, and the insert plates 31 are slidably connected to the first slot 15. A second chuck 37 cooperates with the first chuck 32. When the first chuck 32 and the second chuck 37 are aligned, and the first chuck 32 moves to the inside of the first slot 15 and fits against the second chuck 37, rotating the first handle 33 causes the first chuck 32 and the second chuck 37 to rotate inside the first slot 15, preventing the first chuck 32 from being pulled out of the first slot 15. This connects and fixes the first support frame 1 and the movable frame 3.

[0090] The locking assembly includes a first limiting frame 34 symmetrically fixedly connected to the outer wall of the middle section on both sides of the movable frame 3, and an insert rod 38 fixedly connected to the bottom wall of the top of the first support frame 1. The insert rod 38 is slidably connected to the limiting groove 41. A second sliding rod 35 is fixedly connected to the end of the first limiting frame 34. The second sliding rod 35 is slidably connected to the sliding groove 14 opened on the inner side of the top of the first support frame 1. The second sliding rod 35 and the sliding groove 14 cooperate with each other to support and limit the first limiting frame 34. At the same time, the insert rod 38 cooperates with the limiting groove 41 to support and fix the limiting post 4.

[0091] The lateral movement assembly includes two sliders 51 slidably connected to the outer wall of the slide rail 5. The slide rail 5 supports and limits the sliders 51, allowing them to slide outside the slide rail 5. Two second lead screws 52 are threadedly connected to the inner walls of both sides of the sliders 51. By rotating the second lead screws 52, the second lead screws 52 move towards one side of the sliders 51, thereby pressing the slide rail 5 and causing the sliders 51 to move outward. This increases the friction between the slide rail 5 and the sliders 51, fixing the position of the sliders 51. A first fixing frame 53 is fixedly connected to the outer wall of the sliders 51, supporting and fixing the first fixing frame 53. The first fixing frame 53 is fixedly connected to a sliding sleeve 54, supporting and fixing the sliding sleeve 54.

[0092] The lifting assembly includes a third slide rod 55 slidably connected to the inner side of the sliding sleeve 54, which supports and limits the third slide rod 55 through the sliding sleeve 54; and a third lead screw 56 threadedly connected to the inner side of the sliding sleeve 54, which supports and limits the third lead screw 56 through the sliding sleeve 54. The sliding sleeve 54 and the third slide rod 55 can be fixed by rotating the third lead screw 56. The bottom end of the third slide rod 55 is threadedly connected to the fixing bolt 68.

[0093] The eyelid support assembly includes a second limiting frame 61 fixed to the side wall of the second fixing frame 6, which supports and fixes the second limiting frame 61. A fourth lead rod 62 is threadedly connected to the inner side of the middle section of the second limiting frame 61, supporting and limiting the fourth lead rod 62. A second handle 63 is fixedly connected to the outer end of the fourth lead rod 62, supporting and fixing the second handle 63. A transmission plate 64 is rotatably connected to the inner end of the fourth lead rod 62. Rotating the second handle 63 moves the fourth lead rod 62 towards the second support frame 67, and simultaneously moves the transmission plate 64 synchronously. The moving plate 64 is rotatably connected to the two sides of the first transmission rod 65, and the two ends of the second limiting frame 61 are rotatably connected to the second transmission rod 66. The middle section of the second transmission rod 66 is rotatably connected to the end of the first transmission rod 65 away from the transmission plate 64. The movement of the transmission plate 64 drives the first transmission rod 65 to rotate the second transmission rod 66 around the connection point with the second limiting frame 61 to both sides, so that the end of the second transmission rod 66 opens. The end of the second transmission rod 66 away from the second limiting frame 61 is fixedly connected to the second support frame 67. The second transmission rod 66 supports and fixes the second support frame 67, and the second support frame 67 supports the eyelid.

[0094] The inner side of the support rod 42 is provided with metal reinforcing ribs, while the outer side of the support rod 42 is provided with a silicone layer. The reinforcing ribs can ensure the support of the support rod 42, while the silicone layer can protect the patient's skin.

[0095] The working process of the technical solution provided by this invention is as follows:

[0096] In use, the present invention first inserts the insert plate 31 into the first slot 15 and aligns the first chuck 32 with the second chuck 37. After the first chuck 32 is inserted into the first slot 15 and aligned with the second chuck 37, the first handle 33 is rotated, causing the first chuck 32 and the second chuck 37 to rotate within the first slot 15, preventing the first chuck 32 from being pulled out. This connects and fixes the first support frame 1 and the movable frame 3. During the insertion of the insert plate 31, the limiting groove 41 is first fitted onto the outside of the second slide rod 35, and then the first limiting frame 34 moves towards the limiting post 4. When in motion, the limiting post 4 is limited to prevent it from falling off the outside of the second sliding rod 35. The fixing frame 11 is then fitted onto both sides of the bed. The first screw 12 is then rotated, which drives the top plate 13 to move upwards, thus cooperating with the fixing frame 11 and fixing it to both sides of the bed. The device is then secured. The patient lies on the bed and presses the transmission post 24 towards the limiting sleeve 2. Simultaneously, the transmission post 24 drives the limiting ring 21 and the locking rod 23 to move synchronously, thereby canceling the engagement between the locking rod 23 and the second slot 26, allowing the transmission post 24 and the limiting sleeve 2 to rotate.

[0097] After the angle is rotated, the transmission column 24 is released, and the spring 22 pushes the limiting ring 21 away from the fixed frame 11 with the inner wall of the limiting sleeve 2 as the stress point. At the same time, the limiting ring 21 drives the locking rod 23 and the transmission column 24 to move away from the limiting sleeve 2, so that the locking rod 23 engages with the corresponding second locking groove 26, thereby fixing the angle of the limiting sleeve 2 and the transmission column 24. During the adjustment of the angle of the first support frame 1, the first support frame 1 drives the support rod 42 to rotate synchronously, so that the support rod 42 is sleeved on the outside of the patient's head to support and limit the patient's head. Then, the slider 51 is pushed to move outside the slide rail 5 to adjust the lateral position of the bottom eyelid support assembly. Then the second wire is rotated. Rod 52 fixes the position of slider 51, and at the same time, by pulling the third slide rod 55 to slide inside the sliding sleeve 54, the height of the bottom eyelid support assembly is adjusted. Then, the third lead screw 56 is rotated to fix the position of the third slide rod 55. After the position of the eyelid support assembly is adjusted, the second support frame 67 is inserted into the bottom of the eyelid. Then, the second handle 63 is rotated, which drives the fourth lead screw 62 to rotate synchronously. The fourth lead screw 62 pushes the transmission plate 64 to move towards the second support frame 67. At the same time, the first transmission rod 65 drives the second transmission rod 66 to open to both sides on the side away from the second handle 63, thereby driving the second support frame 67 to move synchronously and open the eyelid.

To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.
