Description

Technical Field

[0001] The present application relates to the technical field of ophthalmic surgery, and in particular to an anti-leakage film for ophthalmic surgery. Background Art

[0002] Ophthalmic surgery, especially intraocular surgery, requires intraocular irrigation fluid and external flushing to complete the operation. Currently, a transparent film with a water storage bag on the side is mainly used clinically. The inner surface of the transparent film is sticky and adheres to the eyelid and the skin surface around the eye socket. When there is water, it will not flow under the film, but flow through the film to the water storage bag on the side, thereby achieving the purpose of preventing water overflow during surgery.

[0003] However, in actual intraocular surgery, the existing water storage bag type transparent film has the following shortcomings:

[0004] (1) Before laying the drape during ophthalmic surgery, the eyelids and surrounding skin should be disinfected with iodine. Applying the surgical patch reduces the adhesion between the patch and the skin. Even if the iodine is wiped dry before applying, the effect is not good, especially in the inner and outer canthus, which are prone to leakage. Even if the effect of the patch is very good, the patch will separate from the skin after repeated flushing.

[0005] (2) When the film is not adhered, the overflowing water will flow under the film and drip onto the operator through the outer or inner canthus along the patient's face. If the patient is an infectious disease, the doctor's risk of infectious disease exposure will increase. Alternatively, the water flushed out of the operated eye will flow up and down the film and between the left and right eyes, increasing the risk of infection. Coughing will also increase the risk of infection of the operated eye.

[0006] (3) During vitreoretinal surgery, the patient's breath will move upward along the gap in the inner canthus, causing the wide-angle lens to fog up, blurring the surgical field and affecting the surgery.

[0007] In short, the effect of the ophthalmic surgical film will directly affect all aspects during and after the operation. Utility Model Content

[0008] The main purpose of the present application is to provide an anti-leakage film for ophthalmic surgery, aiming to solve the above-mentioned problems.

[0009] The technical solutions adopted in this application are as follows:

[0010] An ophthalmic surgery leak-proof film, comprising:

[0011] An upper film, wherein the upper film is a water storage bag type transparent film; and,

[0012] The lower film has a rectangular hole in the center, and eyelid pull tabs for pulling the upper eyelid and the lower eyelid apart to both sides are arranged in the rectangular hole. The lower film includes a protective layer and an adhesive layer, and the protective layer is bonded to both sides of the adhesive layer.

[0013] Optionally, the protective layer is provided with perforated lines, and a lifting sheet is provided where the perforated lines are located.

[0014] Optionally, the protective layer is release paper, and the adhesive layer is a polyurethane film with a surface coated with a pressure-sensitive adhesive.

[0015] Optionally, the outer length and width of the protective layer are greater than the length and width of the adhesive layer.

[0016] Optionally, the lower film is a rectangular structure with a length of 12 cm and a width of 8 cm.

[0017] Optionally, the rectangular hole has a length of 4.5 cm and a width of 3.5 cm.

[0018] Compared with the prior art, the beneficial effects of this application are:

[0019] The embodiment of the present application proposes an anti-leakage film for ophthalmic surgery. The protective layer of the lower film is torn off and then applied to the eyelids and surrounding skin. The upper water storage bag-type transparent film is applied to the surface of the lower film. The double-layer waterproof structure of the upper and lower films makes it difficult for the film to leak and the wide-angle lens to fog up during flushing and soaking during a long operation. Even if the film is not well applied, the double-layer waterproof structure can greatly limit the penetration of liquid into the lower film. The design of the eyelid pull tab can pull the upper and lower eyelids apart during surgery, which is conducive to the edge of the upper film wrapping around the eyelid margin eyelashes, reducing the risk of infection while preventing the eyelashes from affecting the operation.

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0027] Refer to the attached Figure 1 As shown, the embodiment of the present application provides an ophthalmic surgery leak-proof film, including an upper film and a lower film. The upper film is a conventional water storage bag type transparent film. When used, the lower film is attached to the eyelid and the surrounding skin, and the upper film is attached to the surface of the lower film. When intraocular perfusion and external flushing are performed, water and liquid will flow into the water storage bag along the surface of the upper film. The double-layer film structure can greatly prevent the flushing liquid from leaking into the skin surface around the eye.

[0028] In the above, the lower film is a rectangular structure with a length of 12 cm and a width of 8 cm. A rectangular hole 4 with a length of 4.5 cm and a width of 3.5 cm is arranged in the center of the lower film. The rectangular hole 4 is designed to separate the bony eye socket from the movable eyelid. In particular, the rectangular hole 4 is consistent with the design of the bony eye socket, which limits the debonding and leakage of the inner and outer canthus. In addition, an eyelid pull tab 5 for pulling the upper and lower eyelids apart to the sides is arranged in the rectangular hole 4. The eyelid pull tab 5 is shaped like a "convex" structure and can be pulled upward and downward respectively, and can be pasted on the upper and lower sides to open the eyelids. Of course, the lower film is a disposable film, which is sterile and sterilized with ethylene oxide, and the residual amount of ethylene oxide is not more than 10ug / cm2.

[0029] Meanwhile, in the present embodiment, the lower film includes a protective layer and an adhesive layer, and the protective layer is bonded to both sides of the adhesive layer. The protective layer is a release paper, which is a front release paper 2 and a back release paper 3, respectively, and is made of silicon-coated paper material. The adhesive layer is a PU film 1 (polyurethane film) coated with a pressure-sensitive adhesive on the surface. Compared with the upper film made of polyethylene thin material, the polyurethane film is more skin-friendly, softer, and more comfortable. When in use, first tear off the protective layer on one side, bond the adhesive layer to the skin around the eyelid, and then tear off the protective layer on the other side, and bond it to the upper film. Of course, in a preferred embodiment, the outer length and width of the protective layer are greater than the length and width of the adhesive layer. Such a design allows the fingers to not touch the adhesive layer when tearing off the protective layers on both sides to avoid sticking.

[0030] Furthermore, the protective layer is provided with a perforated line 6, and a lifting sheet 7 is provided at the location of the perforated line 6. The advantage of such a design is that the protective layer can be torn off conveniently and easily.

[0031] In summary, the ophthalmic surgery leak-proof film provided in the embodiment of the present application has the following specific usage method:

[0032] After conventional iodine disinfection of the eye and facial skin for three times, after the head is wrapped with a sterile towel, the eye skin and the surrounding iodine are wiped dry with sterile gauze, the release paper on one side of the lower film is torn off, the rectangular hole 4 is aligned with the eye to be pasted so as to be in full contact with the skin, and then the release paper on the other side is torn off, and the eyelid pull-tab 5 is pulled apart to both sides after being fitted with the upper and lower eyelids, and finally the water storage bag type transparent film is pasted on the lower film. It can be seen that the double-layer waterproof structure of the upper film and the lower film makes it difficult to cause the film to leak and the wide-angle lens to fog during flushing and soaking during a long operation. At the same time, even if the film is not pasted well, the double-layer waterproof structure can also greatly limit the leakage of liquid into the lower film, and the design of the eyelid pull-tab 5 can pull the upper and lower eyelids apart to both sides during surgery, which is beneficial for the edge of the upper film to wrap the eyelid margin eyelashes, and reduce the risk of infection while avoiding the eyelashes from affecting the operation.

[0033] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
