Description

Technical Field

[0001] The invention relates to an ophthalmic instrument, in particular to an eyelid opening device. Background Art

[0002] A lid speculum is an instrument used to open the patient's eyelids for surgery. It is helpful for expanding the surgical field and is an indispensable medical device in ophthalmic surgery. The lid speculum will touch the patient's cornea during use and is generally used under corneal anesthesia. In non-surgical situations, patients sometimes need to open their eyelids for treatment, usually by the doctor or the patient using their fingers. Due to finger fatigue and shaking, the eyelid opening will become unstable and the treatment cannot be continued. In addition, if the hand hygiene of the eyelid opening fingers is not in place, there is a possibility of cross infection, which affects the treatment effect. Summary of the invention

[0003] The present invention provides an eyelid opening device in view of the above-mentioned deficiencies in the prior art.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] The invention discloses an eyelid opening device, which is composed of an extrusion ring, a guide groove, an eyelid opening piece, an orbital foot and a drainage port. The extrusion ring, the guide groove, the eyelid opening piece, the orbital foot and the drainage port are connected as a whole. The eyelid opening piece is an ellipse adapted to the eye contour. A eyelid opening hole larger than the diameter of the eye iris is arranged at the center of the eyelid opening piece. The extrusion ring is arranged on the eyelid opening piece and close to the eyelid opening hole. A guide groove is arranged at the connection between the extrusion ring and the eyelid opening piece. The chord length of one side of the extrusion ring is larger than the diameter of the eyelid opening hole, and the chord length of the other side of the extrusion ring is smaller than the diameter of the eyelid opening hole. The drainage ports are arranged at both ends of the long axis of the eyelid opening piece.

[0006] The eyelid opening piece is provided with friction protrusions or adhesive.

[0007] The inner side of the extrusion ring is provided with grooves, and the number of the grooves is greater than or equal to one.

[0008] The groove is connected to an external medicine bottle interface device or an eye atomization device.

[0009] The orbital foot is an elliptical edge protrusion that adapts the eyelid opening piece to the eye contour.

[0010] A catheter fixing ring is arranged on one side of the eyelid opening piece.

[0011] The beneficial effects of the present invention are as follows: the present invention is used for opening the eyelids in a non-surgical situation, and the eyelid opener can be used directly to open the eyelids on the outside of the eyelids without touching the patient's cornea, causing no discomfort or infection; the eyelid opener is fixed through the eye socket, and can use the pressure during fixation to continuously open the eyelids by itself without the need for medical staff or patients to use their fingers to open the eyelids, thereby reducing labor intensity and the chance of infection; there are guide grooves on the eyelid opener, and when the patient undergoes eye atomization treatment, condensed water droplets will not flow into the eyes, thereby providing comfort for the patient's treatment; guide ports are provided on both sides of the eyelid opener, and excess fluid in the patient's eyes can be discharged, making treatment convenient; the eyelid opener is easy to use and can be used by the patient by themselves, thereby reducing personnel costs; the eyelid opener can be equipped with a medicine bottle interface to facilitate the dripping of medicine.

The squeeze ring 1, the guide groove 2, the eyelid opening piece 3, the orbital foot 4 and the drainage port 5 are connected as a whole. The eyelid opening piece 3 is an ellipse adapted to the eye contour. The center of the eyelid opening piece 3 is provided with an eyelid opening hole 6 larger than the diameter of the eye iris. The squeeze ring 1 is placed on the eyelid opening piece 3 and close to the eyelid opening hole 6. The squeeze ring 1 is provided with a guide groove 2 at the connection between the squeeze ring 1 and the eyelid opening piece 3. The chord length of one side of the squeeze ring 1 is greater than the diameter of the eyelid opening hole 6, and the chord length of the other side of the squeeze ring 1 is less than the diameter of the eyelid opening hole 6. The drainage port 5 is provided at both ends of the long axis of the eyelid opening piece 3. The eyelid opening piece 3 is provided with a friction protrusion or an adhesive. The inner side of the squeeze ring 1 is provided with a groove 7, and the number of the grooves 7 is greater than or equal to 1. The groove 7 is connected to an external medicine bottle interface device or an eye atomization device. The orbital foot 4 is an elliptical edge protrusion that is adapted to the eye contour of the eyelid opening piece 3. A catheter fixing ring 8 is provided on one side of the eyelid opening piece 3.
