Description

Technical Field

[0001] This utility model belongs to the field of auxiliary eye drop technology for the elderly, specifically an eyelid opener. Background Technology

[0002] An eyelid speculum is a medical device used in ophthalmic surgery or examinations. Its main function is to open the patient's eyelids to facilitate surgical procedures or examinations. The speculum works similarly to a retractor in surgery, primarily supporting the eyelid. It is typically V-shaped, U-shaped, or Y-shaped, consisting of support arms and eyelid hooks. The rear ends of the two support arms are combined into a handle, while the front ends feature two symmetrically positioned eyelid hooks. These hooks are generally designed as a horizontal L-shape; the vertical portion inserts into the eye socket to fix the eyelid, while the horizontal portion limits the depth of the vertical portion into the eye socket, preventing damage to the eyeball.

[0003] Meanwhile, an eyelid retractor with application number CN202322816450.5 "includes a frame and connecting strips. The frame is through the middle, and a gear is rotatably installed in the middle of the frame. A first magnetic strip and a second magnetic strip are respectively provided on both sides of the gear inside the frame. The first magnetic strip and the second magnetic strip are both meshed with the gear, and the first magnetic strip and the second magnetic strip extend out from both ends of the frame. A connecting strip is provided at the outer end of each of the first magnetic strip and the second magnetic strip, and each connecting strip is detachably provided with a retracting piece." During use, the above-mentioned eyelid retractor limits and tightens the eyelid by clamping it. Without a supporting structure, the external structure is prone to drooping, especially in the elderly whose eyelids are loose, making them more prone to drooping and loosening. The traction force on the eyelid is large, which may lead to the risk of damage to the eyelid or eyeball.

[0004] Therefore, an eyelid opener is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides an eyelid opener that can provide auxiliary support for a curved rod, maintain the stability of the curved rod, and prevent eyelid sagging and damage caused by drooping in the elderly.

[0027] The support assembly 5 includes a rotating shaft 51 rotatably disposed inside the positioning frame 4. A rubber rod 52 is fixedly disposed at the bottom end of the rotating shaft 51, and a support rod 512 is fixedly disposed at the other end of the rubber rod 52. Rotating the rotating shaft 51 controls the support rod 512 to be positioned at the corner of the elderly person's eye, providing auxiliary support for the curved rod 1. A spacer block 6 is fixedly disposed on the outside of the curved rod 1, and a bracket 7 is attached to the surface of the spacer block 6. An elastic rod 8 is fixedly disposed between the two brackets 7. The elastic rod 8 can be positioned on the outside of the curved rod 1 through the brackets 7 and limited by the spacer block 6.

[0028] Specifically, the eyelid clip 2 is a curved clip made of silicone material, which can reduce damage to the eyelids.

[0029] A ratchet 53 is fixedly mounted on the front side of the rotating shaft 51. A limit seat 54 is rotatably mounted on the outer side of the ratchet 53. The ratchet 53 rotates and adjusts inside the limit seat 54, guiding it to different positions. A horizontal shaft 59 is fixedly mounted on the front end of the limit seat 54, penetrating the positioning frame 4. A second spring 510 is sleeved on the outer side of the horizontal shaft 59, fitting against the positioning frame 4. A circular plate 511, fixed to the horizontal shaft 59, is fitted to the other end of the second spring 510. The second spring 510 can push the circular plate 511 to move the limit... The seat 54 is pressed against the outside of the ratchet 53. A fixing block 58 is fitted inside the seat 54. An anti-disengagement buckle 55 that is in contact with the ratchet 53 is slidably arranged inside the fixing block 58. A damper 56 that is fixed to the fixing block 58 is fixedly arranged at the top of the anti-disengagement buckle 55. A spring 57 that is in contact with the fixing block 58 is sleeved on the outside of the damper 56. The spring 57 can push the damper 56 to unfold and push the anti-disengagement buckle 55 to lock into the tooth groove of the ratchet 53, so as to rotate clockwise.

[0031] Working principle and process:

[0032] When the patient uses the curved rod 1, the eyelid clip 2 can be inserted into the inside of the eyelid. By rotating the connecting seat 3, the eyelid clip 2 is placed on the eyelid. The damper 2 9, together with the outer spring 3 10, pushes the elastic rod 8 and the end bracket 7 to lock onto the outside of the curved rod 1. The spacer block 6 limits the movement to prevent it from falling off. The elastic rod 8 opens the curved rod 1, keeping the eyelid open. After opening, the support component 5 located at the bottom of the positioning frame 4 can be rotated to control the rotation of the rotating shaft 51 and the rubber rod 52. This controls the rotation of the ratchet 53 inside the limiting seat 54. When rotating clockwise... The anti-disengagement buckle 55 inside the fixing block 58 can be pushed open continuously, and the damper 56 can be pushed to compress the spring 57. The ratchet 53 can pass smoothly through the limiting seat 54 until the support rod 512 is rotated and fitted to the corner of the eye for positioning. After positioning, it can form a triangular support structure with the curved rod 1 above, which plays a stabilizing role, reduces the pressure of opening the eyelid, and performs the eye drops operation. After the eye drops are finished, the horizontal shaft 59 can be pulled, the spring 510 can be compressed and deformed, and the control plate 511 and the limiting seat 54 can be opened from the outside of the ratchet 53, and the rubber rod 52 can be rotated and removed.
