DETAILED DESCRIPTION

[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The eyelash trimming device for ophthalmic surgery according to an embodiment of the utility model will be described below with reference to the accompanying drawings.

[0023] like Figures 1 to 3 As shown, the eyelash trimming device for ophthalmic surgery of the embodiment of the utility model can evert the patient's eyelids through the provision of a protective frame 200, so that the shearing device 300 can shear the curled eyelashes. By providing a suction pump in the connecting cavity, the sheared eyelash debris can be sucked into the storage cavity for centralized cleaning.

[0024] The ophthalmic surgery eyelash trimmer with application number CN202222524921.0 (hereinafter referred to as "the patent"), by setting the upper end of the base plate in a comb-tooth shape, can make the eyelashes appear from the comb teeth, and trim the eyelashes through the cooperation of the movable component and the trimming component. However, when the base plate is attached to the patient's eyes, due to the proximity of the object, the patient's eyes are closed, so that the eyelashes are close to the eyelids, and some eyelashes cannot be exposed from the comb teeth due to the close contact with the eyelids. Therefore, the cooperation of the movable component and the trimming component cannot effectively trim the patient's eyelashes.

[0025] In addition, when trimming eyelashes, in the actual trimming process, relevant personnel are required to move the movable component on the handheld body, trimming the eyelashes while moving. The whole process is not only cumbersome, but also requires the patient to maintain a continuous posture.

[0026] The eyelash trimming device for ophthalmic surgery of the present invention is provided with a protective frame 200 at the top of the extension part 102 and the bottom of the front end of the collecting chamber 100, respectively. The protective frame 200 is arc-shaped and can fit the patient's eyes. When the patient's eyelashes are trimmed, the protective frame 200 can be squeezed to make the patient's upper eyelid and lower eyelid everted. When the eyelids are everted, the eyelashes are lifted up, and the eyelashes are more easily inserted into the knife net 101.

[0027] In addition, through the shearing of the shearing device 300, that is, the driving motor 310 drives the cam 320 to rotate, so that the cam 320 drives the eccentrically arranged connecting rod 330 to move, and the connecting rod 330 pushes the blade 340 to move. Since the blade 340 passes through the limiting effect of the slide groove and the limiting strip 341, the blade 340 can only move up and down, thereby realizing the up and down reciprocating motion of the blade 340. When the blade 340 moves up and down, the eyelashes extending into the knife net 101 can be trimmed.

[0028] Although this patent adds an eyelash collecting assembly in another embodiment, the eyelash collecting assembly includes an upper card plate and a lower card plate, and the upper card plate and the lower card plate are connected to a collecting bag. The collecting bag is made of latex material and is elastic. In accordance with the change of the movable plate, the upper card plate is connected to the movable plate, and the lower card plate is connected to the fixed plate. During the trimming process, the eyelashes will fall and fall into the eyelash collecting assembly.

[0029] However, in actual use, since the eyelash debris is too light and is easily affected by airflow, the eyelash debris may still fly out after the patient or medical staff makes a large movement. In addition, since the movable component needs to be moved left and right when modifying the eyelashes, the stability of the eyelash debris collection is reduced, and subsequent cleaning is still required.

[0030] The eyelash trimming device for ophthalmic surgery of the present invention can directly suck the debris cut by the shearing device 300 and transfer it to the storage chamber by providing a suction pump in the connecting chamber. Moreover, since the blade 340 is in contact with the extension part 102 and moves up and down, there is no need for the relevant personnel to hold the device to move it horizontally left and right, so the stability is higher when trimming the patient's eyelashes.

[0031] In summary, according to the eyelash trimming device for ophthalmic surgery of the embodiment of the utility model, through the two upper and lower protective frames 200, when trimming the patient's eyelashes, the eyelids can be protected and pressed to make the eyelids everted, which is convenient for observation and trimming, and can also ensure that the trimmer is kept at a safe distance from the eyelids and eyeballs. In addition, a suction pump is provided in the connecting cavity, which can perform suction when trimming the eyelashes to prevent eyelash debris from falling.
