Abstract
Description
Technical Field
[0001] The utility model relates to the field of ophthalmic auxiliary devices, and particularly to a pair of forceps for inspecting rigid contact lenses. Background Art
[0002] Rigid contact lenses include orthokeratology lenses, RGPs, and scleral lenses, which are widely used clinically, mainly for myopia prevention and control, correction of high refractive errors, correction of irregular astigmatism, etc. Generally, rigid contact lenses are not disposable, and their service life is about 1 to 2 years. In addition to material reasons, the key to affecting the service life is proper care. Correct daily cleaning and regular protein removal can extend the service life of the lenses. When the lenses are worn, protein and dirt are deposited and adhered, the lenses should be cleaned or replaced in time. Otherwise, it will not only affect the wearing effect, but may also cause corneal injury or even infection, leading to serious complications. Therefore, during the wearing process, the lenses should be inspected regularly to detect lens problems in time and deal with them accordingly. However, due to the small and transparent lenses, microscopic damage or foreign bodies cannot be directly observed with the naked eye, so doctors need to inspect them under a slit lamp microscope.
[0003] One existing method is that doctors directly pinch the lenses with their fingers for inspection. This method does not conform to the principle of aseptic operation and may cause lens contamination. In addition, a soft silicone clip for contact lenses can assist in lens inspection to a certain extent. However, the silicone clip clamps the lens from the front and back on one side of the lens. When inspecting under a slit lamp microscope, it is difficult to change the angle, resulting in incomplete inspection and low efficiency. In addition, if the force is not applied properly during the inspection, the lens may fall off. There is also a straight-head inspection forceps that directly clamps the lens. If the force is not applied properly, the lens may be broken, and the clamped part is blocked and cannot be inspected. Summary of the Utility Model
[0004] The utility model aims to solve at least one of the technical problems in the above technologies to some extent. For this purpose, the purpose of the utility model is to provide a pair of forceps that can stably clamp a rigid contact lens and does not block the visible area of the lens.

[0025] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.
[0026] When the present utility model is in use, the lens is snapped into the inner lining of the head. The tweezer body remains closed through a self-locking structure and holds the lens; the inner lining can prevent the lens from being contaminated or broken during the clamping process.
[0027] To better understand the above technical solution, exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present utility model can be more thoroughly understood and the scope of the present utility model can be fully conveyed to those skilled in the art.
[0028] To better understand the above technical solution, the above technical solution will be described in detail below in combination with the accompanying drawings of the specification and specific implementation manners.
[0029] Figures 1 to 5 A pair of tweezers for inspecting rigid contact lenses according to an embodiment of the present utility model includes:
[0030] Tweezer body 1: It is provided with a self-locking structure 11 to enable the tweezers to maintain a closed state; the tweezer body 1 has a certain elasticity, and the self-locking structure 11 is locked or unlocked by squeezing the tweezer body 1. During the deformation process, there will be a certain extrusion on the rigid contact lens. To prevent it from being crushed under pressure, an arc-shaped head 2 and an inner lining 3 made of elastic material are provided; specifically, the self-locking structure 11 includes two oppositely arranged hooks 21, and the hooks 21 are arranged on the inner side of the tweezer body 1. With this solution, the structure is completely exposed without sanitary dead corners, which is convenient for disinfection.
[0031] Head 2: Arc-shaped, the outer side is hinged to the tweezer body 1 to enable the head 2 to move relative to the tweezer body 1; the inner side is provided with an inner lining 3 made of elastic material; as described above, in order to prevent the rigid contact lens from being over-extruded during the pressing process of the tweezers, the arc-shaped head 2 of the embodiment of the present utility model, when the tweezer body 1 is closed, the two ends can first abut against each other, maintain less deformation in the internal area through its own rigidity, and in combination with the setting of the inner lining 3, the extrusion received by the rigid contact lens is uniform around the outer area and the overall pressure is small, so as not to cause breakage.
[0032] Specifically, the head 2 and the forceps body 1 are connected by a universal joint or a hinge. Since the forceps body 1 is not completely controllable during the deformation process, there are situations where the head 2 after closing is not aligned and the contact conditions at both ends are different. Therefore, in some solutions, a connection method similar to a ball head universal joint is set between the head 2 and the forceps body 1. In this way, when there is a lens in the head 2, the head 2 will spontaneously swing to adapt to the presence of the lens. The advantage of this solution is that it can effectively ensure that when the forceps body 1 is closed, the force received by the lens is uniform in all directions, and there will be no situation where the force in a certain direction is relatively large.
[0033] In another solution, a hinge is used. The hinge can only swing in a plane. The advantage is that it is convenient to manufacture. When the processing accuracy is high, the out-of-plane force received when clamping the lens can be not considered, and it is more convenient to use the hinge.
[0034] Inner lining 3: The cross-section is crescent-shaped, and the crescent notch faces inward. The inner lining 3 with a crescent-shaped cross-section can be slightly deformed during use, which can prevent the rigid contact lens from moving along the axis in the vertical plane direction, but will not wrap the periphery of the lens, reducing interference with the inspection.
[0035] Specifically, on the side surface of the inner lining 3 in contact with the lens, anti-slip bumps 31 are formed. The purpose of the bumps is to provide fixation to the lens in the form of point contact when the inner lining 3 deforms, reducing the possibility of contaminating the lens.
[0036] Specifically, on the side surface of the inner lining 3 in contact with the lens, a groove 32 for the lens to be inserted is formed. Compared with the above anti-slip bump 31 solution, this solution is more suitable for stably clamping the lens. After the lens can be inserted into the groove 32, the inner lining 3 deforms itself to enclose the periphery of the lens.
[0037] In some embodiments, hooks 21 are provided at both inner ends of the head 2, and the inner lining 3 is correspondingly provided with hanging holes that can be hung on the hooks 21. The inner lining 3 is detachably arranged on the head 2. This method is beneficial for quickly replacing the inner lining 3, and the structure is exposed without sanitary dead corners, which is convenient for disinfection.
