Technical Field

[0001] The utility model relates to the technical field of eyelash trimmers, in particular to a safe eyelash trimmer for ophthalmology. Background Art

[0002] An ophthalmic eyelash safety trimmer is a tool designed specifically for trimming eyelashes. It is usually used by medical professionals, such as ophthalmologists or ophthalmic nurses. Its main function is to help patients solve the problem of excessive or uncomfortable eyelashes, especially for those whose eyelashes may irritate the surface of the eye or cause other eye discomfort symptoms, or to trim eyelashes before eye surgery to prevent eyelashes from affecting the surgery.

[0003] Patients need to trim their eyelashes before undergoing intraocular surgery. For elderly patients with drooping upper eyelid flesh, existing eyelash trimmers are inconvenient to operate and are prone to cutting the flesh of the upper eyelid. If the eyelashes are not trimmed cleanly, the surgical field of view will be poor. Therefore, we propose an ophthalmic eyelash safety trimmer. Summary of the invention

[0027] Example

[0028] like Figure 1-4As shown, the utility model provides an ophthalmic eyelash safety trimmer, comprising a first blade 1 and a second blade 2, and also comprising a rotating shaft 7. The first blade 1 and the second blade 2 are hinged on the rotating shaft 7 in sequence, and a handle is provided at one end of the first blade 1 and the second blade 2. Medical staff can manipulate the first blade 1 and the second blade 2 through the handle to trim the patient's eyelashes.

[0029] In this embodiment, a movable handle 3 is hinged on one side of the rotating shaft 7, and a handle 5 is fixedly installed on the end of the movable handle 3 close to the knife handle. The handle 5 is used to facilitate medical staff to rotate the movable handle 3. The movable handle 3 is hinged on the side of the rotating shaft 7 close to the second blade 2.

[0030] Among them, an isolation ring 8 is fixedly installed on the rotating shaft 7, and the isolation ring 8 is located between the second blade 2 and the movable handle 3. The isolation ring 8 is used to isolate the movable handle 3 from the second blade 2 to prevent the flexibility of the second blade 2 and the first blade 1 from being affected in rotating on the rotating shaft 7 when the movable handle 3 is subsequently fixed by the fixing bolt 10. A screw rod 9 is fixedly installed at one end of the rotating shaft 7 that passes through the movable handle 3, and a limiting plate 11 is fixedly installed on the top of the screw 9. A fixing bolt 10 is fixedly installed on the screw 9, and the movable handle 3 and the rotating shaft 7 are relatively fixed by the fixing bolt 10 and the screw 9.

[0031] like Figure 1 and Figure 4 As shown, a plurality of sets of fixing plates 14 for fixing the upper eyelid flesh are slidably installed on the movable handle 3, an inclined plate 12 is fixedly installed on the side of the top of the movable handle 3 away from the rotating shaft 7, the inclined plate 12 is used to make the fixing plate 14 close to the patient's eyes, a rectangular plate 6 is fixedly installed on the top of the inclined plate 12, a mounting box 4 is fixedly installed on the side of the rectangular plate 6 close to the fixing bolt 10, and the fixing plates 14 are all slidably installed in the mounting box 4.

[0032] Among them, a moving rod 13 is fixedly installed on the back of the fixed plate 14, and the moving rod 13 is slidably installed in the installation box 4. The moving rod 13 passes through the rectangular plate 6 and one end of the installation box 4 is fixedly installed with a connecting plate 17, and a spring 15 is fixedly connected between the connecting plate 17 and the installation box 4. The handle 5 is rotated to make the fixed plate 14 at the top of the movable handle 3 fit with the patient's upper eyelid, and then the handle 5 is rotated to make the fixed plate 14 move upward, thereby driving the patient's upper eyelid flesh to move upward, revealing the root of the eyelashes, which is convenient for subsequent trimming.

[0033] Finally, multiple groups of guide rods 16 are fixedly installed in the installation box 4, and the connecting plates 17 are slidably mounted on the guide rods 16. The guide rods 16 are used to improve the stability of the connecting plates 17 when moving in the installation box 4. Multiple anti-slip strips 18 are fixedly installed on the end of the fixed plate 14 away from the moving rod 13. The anti-slip strips 18 are used to prevent relative sliding between the fixed plate 14 and the patient's upper eyelid, thereby reducing the fixing effect of the fixed plate 14.

[0034] Working principle: During the use of the present invention, the medical staff first puts a finger in the handle 5. During the process of the fixing plate 14 being fitted on the patient's upper eyelid, the multiple fixing plates 14 are respectively located at different positions on the patient's upper eyelid. According to the patient's eye shape, the multiple springs 15 are respectively compressed, and the multiple connecting plates 17 move in the installation box 4, so that the moving rod 13 fixedly connected to the connecting plate 17 also moves, so that the multiple fixing plates 14 are all fitted with the patient's upper eyelid, thereby achieving that the multiple fixing plates 14 can be fitted on the upper eyelids of patients of different types, thereby improving the practicality of the device. After the patient's upper eyelid flesh is lifted and the eyelash roots are exposed, the movable handle 3 and the rotating shaft 7 can be relatively fixed by the fixing bolt 10 and the screw rod 9, so that the medical staff can take the finger out of the handle 5, and then operate the first blade 1 and the second blade 2 through the handle to trim the patient's eyelashes, thereby facilitating the medical staff to use the device with one hand.

[0035] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
