Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically to an eyelid opener. Background Art

[0002] An eyelid speculum is a medical device commonly used in ophthalmic examinations or ophthalmic surgeries. The function of the eyelid speculum is to support the patient's upper and lower eyelids through two hooks, and then open the eyelids through a bracket to expose the eyeball under the eyelids for examination or surgery. The eyelid speculum is helpful in expanding the doctor's surgical field and is an indispensable medical device in ophthalmic surgery. For example, the Chinese patent authorization announcement number is CN220193084U, which discloses an eyelid speculum with self-drainage, including a hand-held plate, both sides of the hand-held plate are fixedly connected to side plates, and the side plates are movably connected to a first adjustment rod, and both ends of the hand-held plate are provided with movable openings. This patented structure drives the first adjustment rod to rotate by turning the handle, so that the eyelid opener arms at both ends can move inward or outward at the same time, thereby driving the eyelid opener hook to open the patient's eyes and adjust the size of the eyelid opening. The second adjustment rod is driven to rotate by twisting the adjustment head. Due to the existence of the thread and the limit cooperation between the limit rod and the limit hole, the rotating second adjustment rod can drive the drainage plate to press against the outer canthus of the patient's eyes. By gently pressing the skin at the outer canthus, the accumulated fluid can flow out, achieving an automatic drainage effect, and increasing the clarity of the surgical field and the success rate of the operation. However, the disadvantage is that the width of the eyelid opener hook is fixed. During the operation, one side of the eyelid opener hook will block the hand and affect the operation. This problem is particularly prominent when performing cataract surgery on the temporal side. For this reason, it is necessary to further improve the existing technology. Summary of the invention
