Description

Technical Field

[0001] This utility model relates to the field of ophthalmic surgical technology, and in particular to an eyelid opening device for ophthalmic operating room care. Background Technology

[0002] Ophthalmic surgical eye retractors, also known as eyelid retractors or eyelid opening devices, are primarily used during ophthalmic surgery to open the patient's eyelids, allowing the surgeon to clearly observe and operate on the surgical site. Below is a brief description of ophthalmic surgical eye retractors: **Eyelid Opening:** During ophthalmic surgery, eye retractors ensure that the upper and lower eyelids are separated, preventing eyelid overlap and providing the surgeon with a clear surgical field. **Surgical Assistance:** Eye retractors help surgeons perform eye surgeries more effectively, especially in procedures requiring precision, such as laser eye surgery.

[0003] Conventional myopia surgery usually uses an eyelid opening device. Most eyelid opening devices are disposable medical instruments, so these eyelid opening devices are all the same size. When used by patients with small eyes, although the pain sensation in the eyeball has been numbed by anesthesia, a slight tearing pain will still occur at the corner of the eye. As the cornea is removed, the tearing pain at the corner of the eye will be aggravated by the pressure of the surgical laser machine on the eyeball. In order to solve this technical problem, this utility model proposes an eyelid opening device for ophthalmic operating room care. Utility Model Content

[0004] The main objective of this invention is to provide an eyelid opening device for ophthalmic operating room care, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An eyelid retractor for ophthalmic operating room care includes a support plate, a support rod is provided on the outside of the support plate, a spring is provided above the support rod, a limit plate is provided on the outside of the support rod, and a threaded rod is threadedly connected to the inner wall of the limit plate.

[0007] Preferably, a pull-in rod is fixedly installed on the outer surface of the support plate, and the outer surface of the pull-in rod is slidably connected to the inner wall of the support rod.

[0008] Preferably, a lever is fixedly installed on the outer surface of the support rod, and a sliding plate is fixedly installed on the outer surface of the support rod. The outer surface of the sliding plate is fixedly installed to both ends of the spring.

[0009] Preferably, a fixing rod is fixedly installed on the outer surface of the support rod, a square plate is slidably connected to the outer surface of the fixing rod, a fixing seat is fixedly installed on the outer surface of the square plate, and the inner wall of the fixing seat is rotatably connected to the outer surface of the threaded rod.

[0010] Preferably, the outer surface of the limiting plate and the outer surface of the sliding piece are slidably connected, and the outer surface of the limiting plate and the outer surface of the sliding piece are in close contact.

[0011] Preferably, the inner wall of the square piece is slidably connected to the outer surface of the support rod, an organic strip is fixedly installed on the outer surface of the square piece, a protective frame is fixedly installed on the outer surface of the square piece, and the inner surface of the protective frame is slidably connected to the outer surface of the organic strip.

[0012] Preferably, a gear is rotatably connected to the outer surface of the square piece, and the outer surface of the gear meshes with the outer surface of the machine bar.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, through the cooperation of the support plate, support rod, spring, limiting plate, and threaded rod, the spring can lift the support rod, allowing the support rod to open the eyelid. Before cutting the cornea, the patient can be questioned in advance. If it is found that the patient can clearly feel pain in the corner of the eye, eyelid, or eyelid, the threaded rod can be rotated. The threaded rod can drive the limiting plate, causing the limiting plate to press the support rod, thereby reducing the distance between the support rod and the support plate, thus reducing the width of the eyelid opening and reducing the patient's pain. This solves the problem of slight tearing pain in the corner of the eye for patients with small corners of the eyes.

[0015] In this invention, the support plate, the insertion rod and the support rod are connected to each other through the threaded seat and the nut, so that the support plate and the insertion rod can be made of disposable materials, which can reduce the spread or infection of bacteria and reduce the cost of the product.

[0016] In this invention, through the cooperation between gears, machine bars and support rods, when a single support rod moves, it can drive the gear through the machine bar. When the gear rotates, it can drive another machine bar, so as to ensure that the two support rods maintain the same speed and interact in the same direction of movement. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-5 As shown, an eyelid opening device for ophthalmic operating room care includes a support plate 1, a support rod 2 disposed on the outside of the support plate 1, a spring 5 disposed above the support rod 2, a limiting plate 3 disposed on the outside of the support rod 2, and a threaded rod 4 threadedly connected to the inner wall of the limiting plate 3. The spring 5 can lift the support rod 2, enabling the support rod 2 to open the eyelid. Before corneal cutting, the patient can be questioned in advance. If it is found that the patient can clearly feel pain in the corner of the eye, eyelid, or eyelid, the threaded rod 4 can be rotated. The threaded rod 4 can drive the limiting plate 3, causing the limiting plate 3 to forcefully press the support rod 2, thereby reducing the distance between the support rod 2 and the support plate 1, thus reducing the width of the eyelid opening and reducing the patient's pain. This solves the problem of slight tearing pain in the corner of the eye when used by patients with small corners of the eyes.

[0025] A pull rod 6 is fixedly installed on the outer surface of the support plate 1. The outer surface of the pull rod 6 is slidably connected to the inner wall of the support rod 2. The pull rod 6 and the support rod 2 can be connected to each other through a threaded seat and a nut, so that the support plate 1 and the pull rod 6 can use disposable materials, which can reduce the spread or infection of bacteria and reduce the cost of the product.
