Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an eyelid opener for ophthalmic surgery. Background Technology

[0002] Eyelid speculum are indispensable medical instruments in ophthalmic surgery, used to open the patient's eyelids during the procedure to facilitate the expansion of the surgical field. However, when using eyelid speculum for eye surgery, the eyes are exposed to the external environment for extended periods, which can easily lead to dryness and even secondary eye infections. Therefore, medical staff need to inject saline solution or other fluids to moisten the eyeballs, a cumbersome, time-consuming, and labor-intensive procedure.

[0003] Utility model patent CN215384274U discloses an eyelid retractor for ophthalmic surgery, including a support rod. Clamping rods are rotatably connected to both ends of the support rod. A spreading rod is positioned above the other end of each clamping rod. A spreading handle is fixedly connected to the upper end of the spreading rod. An internal cavity is formed at the end of the clamping rod closest to the spreading rod. A sliding groove is provided above the internal cavity. A spring is positioned at the bottom of the internal cavity, with its lower end contacting the bottom of the internal cavity. A circular plate is fixedly connected to the upper end of the spring. The lower end of the spreading rod passes through the sliding groove to the inner end of the internal cavity. Clamping devices that cooperate with the sliding groove are fixedly connected to the two side walls of the lower end of the spreading rod located at the inner end of the internal cavity. A fixing ring is fixedly connected to the outer wall of the lower end of the clamping rod. A connecting pipe is fixedly connected to the outer wall of the spreading rod between the spreading handle and the clamping rod. A rubber tube is provided on the outer wall of the support rod. A central rod is provided at the center of the support rod. The lower end of the central rod passes through the support rod and is threadedly connected to the support rod. A support rod is rotatably sleeved on the upper end of the central rod. The upper end of the central rod passes through the center of the support rod and is fixedly connected to a fixing plate. Movable rods are rotatably connected to both ends of the support rod. A groove is provided on the clamping rod near the center of the support rod. The other end of the movable rod is hinged to the inner wall of the upper end of the groove. This solution can disinfect, rinse, and moisturize the eyes by opening a rinsing hole on the outer wall of the support handle to avoid dry eyes and secondary bacterial infections, which is beneficial to eye recovery. However, the structure of this solution is relatively complex, the cost is high, and it is not convenient to clean. Therefore, it is necessary to improve the existing eyelid opener for ophthalmic surgery. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing an ophthalmic surgical eyelid opener that solves the technical issues of high cost and inconvenience in cleaning of traditional ophthalmic surgical eyelid openers that can disinfect, rinse, and moisten the eyes.

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

[0006] An ophthalmic surgical eyelid retractor includes two support rods, an elastic element, an opening and closing locking structure, two eyelid retractors, and a liquid supply device. One end of each of the two support rods is hinged to the other, and the elastic element abuts against the two support rods, causing the other ends of the two support rods to tend to open. The opening and closing locking structure is connected to the middle of the two support rods, and the opening and closing locking structure can lock the two support rods relative to each other. A first cavity is provided in the movable end of each support rod, and a connecting end is provided on the support rod to connect to the first cavity. Each support rod has an eyelid retractor at its opening and closing end, and the eyelid retractor is connected to the support rod through a rigid connecting tube. A second cavity is provided in each eyelid retractor, and the second cavity communicates with the first cavity through the connecting tube. Liquid outlet holes are provided on the opposite sides of the two eyelid retractors. The liquid supply device is connected to the connecting end.

[0007] Furthermore, the liquid supply device includes a liquid container, a hose, a liquid pump, and a switch. One end of the hose is connected to the connection end, and the other end of the hose is connected to the bottom of the liquid container. The liquid pump is installed on the hose, and the switch controls the start and stop of the liquid pump.

[0008] Furthermore, the switch is a foot switch.

[0009] Furthermore, the elastic element is a torsion spring, and the two ends of the torsion spring are provided with hooks, which hook against the side of the support rod.

[0010] Furthermore, the opening and closing locking structure includes an arc-shaped component and a locking knob. One end of the arc-shaped component is fixedly connected to the middle of one of the support rods. An arc groove is provided in the middle of the arc-shaped component. The locking knob passes through the arc groove and is screwed into the middle of the other support rod.

[0011] Furthermore, the outer wall of the locking knob is provided with an anti-slip texture.

[0012] Furthermore, the outer wall of the connecting end is provided with several anti-loosening tooth rings.

[0013] Furthermore, the support rod is arched.

[0014] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0015] 1. When this utility model is used in ophthalmic surgery, the two eyelid opening parts are aligned and inserted into the patient's upper and lower eyelids respectively. After the support rod is opened to the appropriate position, the position is fixed by the opening and closing locking structure. Through the liquid supply device, the required liquid can flow into the patient's eyeball through the connecting end, the first cavity, the connecting tube, the second cavity and the liquid outlet. This utility model can facilitate the injection of liquid into the eyeball of ophthalmic surgery patients and keep the eyeball moist. At the same time, the support device has a simple structure, low cost and easy cleaning, solving the technical problems of high cost and inconvenient cleaning of traditional eyelid opening devices used in ophthalmic surgery that can disinfect and moisten the eyes.

[0016] 2. This utility model features a foot-operated water supply switch, allowing doctors to operate using both hands and feet during surgery. This simplifies operation and reduces the risk of eye infection for patients due to hand contamination from contact with the switch. The torsion spring design makes the automatic opening mechanism of the support rod simple, inexpensive, and highly reliable. The opening and locking structure is simple to design; operation involves only tightening and loosening the locking knob, making it easy and convenient. The anti-slip texture further enhances the grip and ease of use. The anti-detachment toothed ring prevents the hose from loosening, improving the reliability of the hose connection. The arched support rod allows the device to conform to the shape of the patient's face, facilitating placement. Attached Figure Description
