Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and relates to a corneal protector (eye shield) for surgery, in particular to a monolithic silicone eye shield for eye surgery. Background Art

[0002] During eyelid plastic surgery and radiofrequency treatment (Thermage) of the eye skin, in order to prevent accidental injury to the cornea during the operation or procedure, it is necessary to protect the eyeball. Currently, a two-piece instrument such as the "Eye Ball Protective Cover" with the Chinese Patent Publication No. CN214967593U is used, which includes a semi-spherical body and a suction column for adsorbing the body. The operation steps are divided into two steps. First, the body is adsorbed by the suction column, and then the eyelid is opened to place or remove the body from the surface of the eyeball. During clinical surgery or treatment, the operation of this set of instruments is not convenient and scientific. First, it is difficult to operate when placing and removing the body: Before the operation or radiofrequency operation, since the above-mentioned body cannot be directly placed on the patient's eyeball, it is necessary to first apply antibiotic eye ointment on the eyeball surface (concave surface) of this body for lubrication and anti-infection to avoid exfoliative inflammation caused by corneal friction. Therefore, at the end of the operation, there will be a very slippery layer of eye ointment on the surface of the body that protects the cornea. It is very difficult for the above-mentioned suction column to firmly adsorb the body, and it needs to be adsorbed repeatedly for many times. When it still fails in the end, the doctor can only use a medical forceps with teeth at the tip to clamp the body and then remove it. In fact, when clamping the body with the forceps, the doctor still needs to be particularly careful, fearing both slipping and not being able to clamp it and the tip of the forceps hurting the eyeball and cornea. Such an operation is difficult and time-consuming, and very inconvenient! Second, the discomfort of the patient is too strong: The negative pressure of the above-mentioned suction column is very small, and the body will fall off with a little external force when the body is lifted. Therefore, when the doctor places it, he must fully open the patient's upper and lower eyelids to completely expose the front end of the eyeball. The patient has a strong sense of discomfort, and it is even more difficult to place for patients with a narrow eye socket. Repeated placement many times causes the patient to feel uncomfortable and painful and reluctant to cooperate; when the body needs to be removed at the end of the operation, the doctor will open the patient's eyelids again and repeat the operation when placing it before. At this time, since the surface of the eye shield is already full of eye ointment, it is even more difficult for the suction column to adsorb the body, resulting in more time spent in removing the body, and the patient's eyelids need to be kept open passively, increasing the pain and discomfort. Summary of the Invention

[0003] Aiming at the problems of inconvenient operation of the eye shield and pain for both doctors and patients in the prior art, the purpose of the instrument of the present utility model is to provide a monolithic silicone eye shield, which is convenient for doctors to place and remove, reduces the pain of patients, and improves the surgical efficiency.

[0004] To achieve the above purpose, the specific implementation technical solutions adopted by the present utility model are as follows:

[0005] A monolithic silicone eye shield for eye surgery, characterized in that: the eye shield consists of two parts, including a spherical crown-shaped shell covering the eyeball and a protrusion on the outer surface of the shell; the thickness of the spherical crown-shaped shell is uniform or thicker in the middle and thinner at the edges, and the protrusion is an arc surface that gently protrudes from the edge, with the center of the protrusion located at the middle tangent arc position of the outer surface of the spherical crown-shaped shell, and there is a gap between the middle position of the protrusion and the outer surface of the spherical crown-shaped shell; during operation, use an ophthalmic forceps to clamp the protrusion part and place the eye shield in, with the inner surface of the spherical crown-shaped shell covering the eyeball, and when removing, use the ophthalmic forceps to clamp the protrusion part or insert it into the middle gap of the protrusion to remove the eye shield.

[0006] The protrusion is in an arch shape or a spherical shape, and the perpendicular distance from the highest point of the protrusion to the outer surface of the spherical crown-shaped shell is not greater than 1.5 mm.

[0007] The center point of the protrusion is located at one-third to two-thirds of the middle tangent arc distance from the edge.

[0008] The thickness of the spherical crown-shaped shell is 0.2 mm to 0.4 mm.

[0009] The diameter of the tangent plane of the spherical crown-shaped shell is 16 mm to 20 mm.

[0010] The protrusion is provided at the inner canthus position or one protrusion is provided at each of the inner canthus and outer canthus positions.

[0011] The positive and beneficial effects produced by the present utility model are: due to the provision of a protrusion with a gap, it is easy to clamp, meeting the requirements of simplicity and convenience of eye surgery instruments. It seems to be a very simple improvement, just making a clamping protrusion on the shell, but it solves a major problem in the actual operation process, making it convenient, simple, time-saving, and labor-saving for doctors, and enabling patients to avoid repeated insertion and removal, reducing pain, and producing great practical beneficial effects.

[0016] In the figure, 1. Spherical crown-shaped shell, 2. Protrusion, 3. Gap. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Such asFigure 1 , Figure 2 As shown, the protrusion 2 of Embodiment 1 is an arched protrusion. There is a gap 3 between the middle part of the protrusion 2 and the spherical crown shell 1. The diameter of the tangent plane of the spherical crown shell 1 is 20 mm, the thickness of the spherical crown shell 1 is 0.3 mm, the length of the protrusion 2 is 8 mm, the width is 2 mm, the center position of the protrusion 2 is at the midpoint of the middle cutting arc of the spherical crown shell 1, the protrusion 2 is 1.5 mm away from the outer surface of the spherical crown shell 1, and the length of the gap 3 is 4 mm.

[0018] As Figure 3 , Figure 4 shown, the protrusions 2 of Embodiment 2 are spherical protrusions, with one set on each side. There is a gap 3 between the middle part of the protrusions 2 and the spherical crown shell 1. The diameter of the tangent plane of the spherical crown shell 1 is 16 mm, the thickness of the spherical crown shell 1 is 0.3 mm, the diameter of the cross-section of the protrusion 2 is 5 mm, the center position of the protrusion 2 is at one-third of the middle cutting arc of the spherical crown shell 1, the protrusion 2 is 1 mm away from the outer surface of the spherical crown shell 1, and the length of the gap 3 is 2.5 mm.

[0019] During operation, after applying the ointment evenly on the inner surface of the spherical crown shell 1 of the eye shield, pick up the protrusion 2 with an ophthalmic forceps. Without inserting it into the gap 3, the clamping area is increased, and then it is placed on the eyeball. When taking it out, since a negative pressure is generated between the spherical crown shell 1 and the eyeball and it is sucked tightly on the eyeball, and it is easy to slip due to the applied ointment, an ophthalmic forceps or a medical hook is inserted into the gap 3 between the protrusion 2 and the inner surface of the spherical crown shell 1, and the eye shield is slowly pulled out. One operation can be successful without slipping off.
