To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components have been omitted from the present disclosure.

Referring to fig. 1 to 4, an eyelid retractor for ophthalmologic care according to an embodiment of the present invention includes a V-shaped body 1 for providing pretension, the body 1 has a first retractor arm 11 and a second retractor arm 12 which are symmetrical, and the free ends of the first retractor arm 11 and the second retractor arm 12 are respectively provided with a retractor 2 for fitting an eyelid, as shown in fig. 1 and 4, in this embodiment, the retractor 2 includes a baffle 22 and a retractor plate 23 disposed on one side of the baffle 22, and the retractor plate 23 needs to contact the eye position of a patient in use, so that the retractor plate 23 is preferably configured as an arc plate with an arc 231 for fitting an eyeball structure. Meanwhile, after the eyelids of the patient are opened, in order to limit the position of eyelid, a limiting rod 21 may be further disposed on the other side of the baffle 22 opposite to the opening plate 23. In the embodiment, although the body 1 itself can provide a certain outward stretching tension after being formed, however, this tension supply preset is small, and for most adult patients, is not sufficient to provide a stable distraction force, therefore, in this embodiment, the inner side surface of the main body 1 is provided with a first slot 14, a first plug connector 3 is further inserted into the first slot 14, the first plug connector 3 is also made of an elastic material, for example, Polyvinyl chloride (PVC), Polyethylene (PE, Polyethylene), polypropylene (PP, polypropylene), Polystyrene (PS) and K resin, ABS, Acrylonitrile Butadiene Styrene (Acrylonitrile Butadiene Styrene copolymers), Polycarbonate (PC, Polycarbonate), PTFE (polytetrafluoroethylene), etc., which may also be used for processing the body 1. First plug connector 3 with 1 length adaptation of body just has and corresponds respectively first arm 11 that struts with the second struts the first arm 31 and the second of popping one's arms 32 of popping one's arms 12, first arm 31 of popping one's arms 31 with the second is popped one's arms 32 and is gone up and be constructed a plurality of rupture grooves 34 along its width direction, and is followed a plurality of rupture grooves 34 break during first plug connector 3, the elastic tension that first plug connector 3 provided changes. Specifically, the first connector 3 is a fitting assembled on the body 1 during use, and the predetermined breaking groove 34 can be conveniently broken, so that the medical staff can symmetrically change the lengths of the first elastic arm 31 and the second elastic arm 32 according to actual needs, and since the first connector 3 is inserted into the inner side of the body 1, the first connector 3 of the same specification can provide the rated maximum supplementary tension when the first connector is at the maximum length, and the effective supplementary tension which can be provided by the first connector can be reduced if the lengths of the first elastic arm 31 and the second elastic arm 32 are changed along the breaking groove 34. In addition, in order to provide linear supplementary tension, in a further modification, the spacing between the breaking grooves 34 distributed on the first and second

elastic arms

31 and 32 may be set to be non-linear, for example, the spacing of the breaking grooves 34 closer to the free end is larger, and the spacing closer to the bent portion is smaller, and for convenience of practical operation, the spacing is preferably arranged in an arithmetic progression.

Further, in the present invention, the first connector 3 may actually be directly inserted into the first slot 14, or a plurality of engaging holes 15 may be disposed in the first slot 14, and correspondingly, a plurality of engaging posts 33 cooperating with the engaging holes 15 may be disposed on the first connector 3. With this structure, the first connector 3 can be fixed relatively firmly in the first slot 14. More specifically, as shown in fig. 1, the clamping column 33 includes a cylinder (not labeled in the figure) and a clamping head (not labeled in the figure) located at the top end of the cylinder, the diameter of the clamping head is greater than the diameter of the cylinder and is at least composed of a first clamping head 331 and a second clamping head 332 which are oppositely arranged, and a gap 333 is left between the first clamping head 331 and the second clamping head 332. Therefore, when the first connector 3 is inserted into the first slot 14, it is not easy to be taken down again, and the second use is avoided.

As mentioned above, the main body 1 may also be formed by bending an elastic material the same as the first connector 3, so that the line of sight of the medical care worker is not affected by the operation, and the main body 1 may be designed to gradually decrease along the width from the bent portion to the free end.

Fig. 5 shows a schematic structural diagram of the second connector 4, the second connector 4 can further supplement the elastic tension of the body 1, and similarly, it can be made of the same medical plastic as the body 1, in this embodiment, preferably, a second slot 13 is opened on the outer side surface of the body 1, and the second connector 4 for providing the supplementary tension is inserted into the second slot 13. Specifically, unlike the first connector 3, the second connector 4 preferably includes the substrate 41 and the flexible backing 42 made of medical plastic, and the flexible backing does not provide elastic force and may be made of medical silicone. So that the medical care worker can provide proper friction support during operation, and misoperation is avoided. In addition, as a further improvement, as shown in fig. 6, in the technical solution of the present invention, a plugging member 5 may be further included, the plugging member 5 is made of medical plastics and includes a plurality of plugging units 51, the plurality of plugging units 51 are connected by a breakable thin-walled structure, correspondingly, a plurality of plugging holes 421 may be disposed on the flexible liner plate 42, and a plurality of plugging units may be fittingly inserted into the plugging holes 421, so that the bending performance of the flexible liner plate 42 is at least partially changed. This allows fine adjustment of the tension that can be provided by the second plug 4. As shown in the drawings, in some embodiments, the plugging holes 421 are configured as circular holes, and in this case, the plugging units 51 are configured in a shape adapted to the plugging holes 421, but the plugging units 51 may be actually processed in a semi-cylindrical shape, in other words, a more flexible configuration may be achieved by adapting two semi-cylindrical plugging units 51 to the cylindrical plugging holes 421. It should be noted that the above structure is merely exemplary, and the plugging hole 421 may be actually processed into a semicircular column shape, even a prism shape, or other shapes, and the purpose of the present invention is to achieve fine adjustment of the elastic tension of the second connector 4 by the plugging unit 51.

In addition, as shown in fig. 1, preferably, at least a part of the width of the notch of the first slot 14 and/or the second slot 13 of the body 1 is smaller than the width of the slot body, so that the first connector 3 or the second connector 4 is convenient to insert and fix. Preferably, the width of the first slot 14 and/or the second slot 13 gradually decreases from the bending part of the body 1 to the free end thereof; correspondingly, the shape of the first plug connector 3 or the second plug connector 4 is matched with the first slot 14 or the second slot 13.

Finally, it should be noted that the matching relationship between the first connector 3 and the second connector 4 of the present invention and the first slot 14 and the second slot 13 is not fixed, in practical use, the second connector 4 can still be inserted into the first slot 14 according to needs, and meanwhile, two opposite plug holes 421 on the second connector 4 can be clamped by common tweezers and other similar instruments, or fixed by another adaptive "door" -shaped clamping member, which is not shown in the present invention and is only suitable for the case where the second connector 4 is located in the inner first slot 14, and during specific operation, two pins of the door-shaped clamping member are located in the two opposite plug holes 421.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
