Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a corneal fixation ring. Background Art

[0002] When using intense pulsed light to treat dry eyes, using carbon dioxide laser for scarring or rejuvenation treatment around the eyes, and using laser to treat red bloodshot eyes, port-wine stains, or nevus of Ota, a fixation ring will be fitted over the eyeball to protect it, thereby providing some protection to the eyeball during treatment.

[0003] However, the fixing rings in the prior art are made of silicone, rubber or plastic materials, which absorb light and deform during strong light emission, and even adhere to tissues. The stainless steel fixing rings in the prior art do not have a handle for taking and placing, and the fixing ring placement and angle adjustment during surgery are inconvenient.

[0004] In view of the inconvenience of using the fixing ring in the prior art, the difficulty in observing whether it is dislocated during surgery, and the easy occurrence of invalid occlusion, which leads to the problem of tissue adhesion, a more reasonable technical solution is needed to solve the current technical problems. Utility Model Content

[0005] The utility model aims to provide a corneal fixation ring to solve the problems in the prior art that the fixation ring is inconvenient to use and may be deformed or even adhere to tissues.

[0006] In order to achieve the above object, the utility model provides a corneal fixation ring, comprising:

[0007] A membrane flap made of an alloy material is configured as a spherical structure adapted to the eyeball to form a concave surface concave toward the eyeball, and the membrane flap is used to fit the eyeball; and

[0008] A support rod having a basic length, one end of which is connected to the convex surface of the membrane flap;

[0009] The main view surface of the membrane flap is elliptical, and the edge of the membrane flap is provided with a smooth rounded corner.

[0010] In a possible design, the support rod and the membrane petal are formed into a whole by welding.

[0011] In a possible design, the membrane flap and the support rod are both made of stainless steel.

[0012] In a possible design, both the concave surface and the convex surface of the membrane petal are heat-treated and polished to form a matte sand surface.

[0013] In a possible design, both the concave surface and the convex surface of the membrane flap are configured as polished bright surfaces.

[0014] In a possible design, a handle is provided at the end of the support rod, and a mark for identifying the direction of the corneal fixation ring is provided at the top of the handle.

[0015] In a possible design, a mark is provided on the membrane petal.

[0016] Through the above technical solution, the membrane flap made of alloy material can effectively protect the eyeball and avoid accidental injuries that may occur during treatment. In addition, the membrane flap has the characteristics of less light absorption, fast heat dissipation and no deformation, and can maintain structural stability during treatment. At the same time, the doctor can adjust the angle of the fixing ring as needed to ensure accuracy and safety during treatment. The corneal fixing ring is a safe and effective treatment tool suitable for promotion and application in clinical practice.

[0017] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] 1-membrane flap, 11-concave surface, 12-convex surface, 2-support rod, 3-handle. DETAILED DESCRIPTION

[0023] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0024] See also Figure 1 and Figure 2 As shown, the corneal fixation ring includes: a membrane flap 1 made of an alloy material, which is configured as a spherical structure adapted to the eyeball to form a concave surface 11 concave toward the eyeball, and the membrane flap 1 is used to fit the eyeball; and a support rod 2, which has a basic length, and one end of the support rod 2 is connected to the convex surface 12 of the membrane flap 1; wherein the main viewing surface contour of the membrane flap 1 is elliptical, and the edge of the membrane flap 1 is provided with smooth rounded corners.

[0025] The process of using the corneal fixation ring is as follows: 1. Clean the face; 2. Use surface anesthesia to anesthetize the surface of the eyeball; 3. Protect the cornea and iris, and choose a sterilized corneal fixation ring of appropriate specifications; 4. Hold the support rod 2, and apply eye lubricant to the concave surface 11 of the membrane flap 1; 5. When placing the membrane flap 1 into the upper eyelid, the patient's eyeball looks downward; when placing it into the lower eyelid, ask the patient to look upward; 6. During treatment, hold the corneal fixation ring steadily, touch it gently, and do not press or shake it excessively to avoid causing pain.

[0026] Through the above technical solution, the membrane flap 1 made of alloy material can effectively protect the eyeball, absorb less light, dissipate heat quickly and does not deform, and can maintain structural stability during treatment. The angle of the fixing ring can be adjusted during use to ensure the correct position.

[0027] The use process of the corneal fixation ring is as follows: first, the patient cleans his face thoroughly to keep the surface of the eyeball clean. Next, the doctor will perform surface anesthesia on the surface of the eyeball to ensure the comfort and safety of the patient during the treatment. Then, the doctor will select a sterilized corneal fixation ring of appropriate specifications to protect the cornea and iris. While holding the support rod 2, the doctor will apply an appropriate amount of eye lubricant to the concave surface 11 of the corneal flap 1 to reduce friction and pain that may occur during the treatment. When placing the membrane flap 1 into the upper or lower eyelid, the doctor will guide the patient to adjust the direction of the eyeball as needed to ensure the correct placement of the membrane flap 1. During the treatment, the doctor will keep his hands stable and gently touch the corneal fixation ring to avoid excessive pressure or shaking to avoid causing pain or discomfort to the patient.

[0028] Through the above technical solution, the membrane flap 1 made of alloy material can effectively protect the eyeball and avoid accidental injuries that may occur during treatment. In addition, the membrane flap 1 also has the characteristics of less light absorption, fast heat dissipation and no deformation, and can maintain the stability of the structure during treatment. At the same time, the doctor can adjust the angle of the fixing ring as needed to ensure the accuracy and safety of the treatment process. The corneal fixing ring is a safe and effective treatment tool suitable for promotion and application in clinical practice.

[0029] In an embodiment provided by the present disclosure, the support rod 2 and the membrane petal 1 are welded to form a whole, which is convenient for production and manufacturing, and is also beneficial for ensuring the strength of both.

[0030] In the disclosed embodiment, the support rod 2 and the membrane petal 1 are processed into an integrated structure through an efficient and precise welding process. This design not only simplifies the production process, but also greatly improves the production efficiency. More importantly, this design ensures a tight connection between the support rod 2 and the membrane petal 1, so that it can fully exert its function during use.

[0031] During the production process, after being tempered by extreme environmental conditions such as high temperature and high pressure, its structure has become more compact, and key indicators such as tensile strength and compressive strength have been significantly improved. Through the one-piece molding method, the strength of the support rod 2 and the membrane petal 1 is fully guaranteed, and the appearance of the support rod 2 and the membrane petal 1 is more coordinated and beautiful. This not only improves the overall texture of the product, but also provides users with a better user experience.

[0032] In an embodiment provided by the present disclosure, the membrane flap 1 and the support rod 2 are made of stainless steel. This material has excellent corrosion resistance and strength, and can effectively ensure the long-term stable operation of the corneal fixation ring.

[0033] In one embodiment of the present disclosure, the concave surface 11 and the convex surface 12 of the membrane flap 1 are both heat-treated and polished to form a matte sand surface (which visually presents a frosted effect but is still smooth to the touch). This can appropriately reduce the reflection of the light source and reduce the intensity of the effect on the tissue.

[0034] It should be noted that the sand surface referred to here refers to a matte surface that tends to have poor reflectivity visually, but after surface treatment, it appears to be a smoother surface than the polished surface.

[0035] In another embodiment, the concave surface 11 and the convex surface 12 of the membrane flap 1 are both configured as polished bright surfaces. This configuration enables the membrane flap 1 to effectively reflect the light source during application, thereby performing secondary heating on the tissue.

[0036] In another embodiment, the concave surface 11 and the convex surface 12 of the membrane flap 1 are finely polished to present a smooth mirror-like bright surface. Such a setting not only enables the membrane flap 1 to have efficient heat transfer performance during application, but also can effectively reflect the light source. When light is irradiated onto the membrane flap 1, the reflected light can heat the tissue again, thereby achieving a secondary heating effect. This secondary heating can further enhance the heating effect of the tissue and improve the uniformity and efficiency of heating.

[0037] In one embodiment, a handle 3 is provided at the end of the support rod 2 to increase the grip of the fingers and facilitate accurate adjustment of the position of the flap 1. A mark is provided at the top of the handle to identify the direction of the corneal fixation ring, so that the operator can operate in the correct direction.

[0038] Specifically, the handle 3 can be configured as a sphere, and this spherical structure can provide an excellent hand feel, making the fingers feel more comfortable and stable when holding. At the same time, this spherical design is also beneficial for smoothly adjusting the position of the membrane flap 1, making the adjustment process more stable and accurate.

[0039] Furthermore, the spherical design can enhance the friction between the fingers and the support rod 2, making the fingers more stable when picking up or adjusting, thereby improving the accuracy and stability of the operation. In addition, since the end of the support rod 2 with a spherical design has a better hand feel, the operator can feel a more direct and effective grip during use.

[0040] Of course, any other suitable handle 3 may also be provided at the end of the support rod 2 .

[0041] The membrane petal 1 is provided with a mark, so that the angle of the fixing ring can be adjusted during use to ensure the correct position. Specifically, the mark can be an arrow or a letter or a word.

[0042] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.
