As shown in fig. 1, the present invention provides a heavy eyelid designer, which includes a handle 1, a sliding assembly 2, and a wire 3. After the wire 3 is bent, both ends thereof are placed in the slider assembly 2, and the arc portion 31 is exposed outside the handle 1. The sliding assembly 2 is connected to the handle 1 and can slide along a track on the handle 1. By controlling the movement of the sliding component 2, the position of the sliding component 2 for restraining the metal wire 3 is changed so as to adjust the radian of the arc-shaped part 31, and the method specifically comprises the following steps: advancing the slider assembly 2 in a direction adjacent the wire arcuate section 31, the radius of the wire arcuate section 31 becoming shorter; pulling the slider assembly 2 away from the wire arcuate section 31 lengthens the radius of the wire arcuate section 31. In some embodiments, the wire 3 is covered with a wire protection layer 5 on the outside of both ends of the wire 3 to reduce the abrasion of the wire 3 caused by the side wall of the sliding member 2 when the sliding member 2 slides along the rail and binds the wire 3. During the sliding process of the sliding assembly 2, the wire protective layer 5 and the wire 3 are kept fixed, so that the arc length of the arc-shaped part 31 is kept unchanged all the time, namely, the radius of the arc-shaped part 31 is changed only by moving the sliding assembly 2. Optionally, the arc length of the arc portion 31 is 20mm to 25mm, in this example, the arc length of the arc portion 31 is 22 mm. The radius of the arcuate portion 31 varies within the range of 10mm to 25 mm. Before operation, the surgeon can adjust the arc by moving the sliding assembly 2 to adjust the morphology of the patient's double lid line. On the handle 1, corresponding to the area where the sliding component 2 can slide, scales are provided, which can help the doctor to record the sliding distance of the sliding component 2 and determine the proper radian of the arc-shaped part 31. The surface of the sliding component 2 is provided with anti-skid lines, which is convenient for the doctor to control the movement of the sliding component 2.

As shown in fig. 2 and 3, the sliding assembly 2 includes a key 21, a spring 22, a fixing seat 23 and a fixing block 24. In the use state, the elastic sheet 22 and the fixed block 24 are arranged in the fixed seat 23, and the two ends of the metal wire 3 are inserted into the through hole 240 formed at the far end of the fixed block 24. The button 21 can drive the fixed seat 23 to slide along the track on the handle 1 to change the length of the wire arc 31. In some embodiments, the inner side of the key 21 is provided with a protrusion 210 capable of being embedded in the fixing seat 23 for driving the fixing seat 23 to move.

The proximal end of the elastic sheet 22 is provided with a bending structure 220, the handle 1 is provided with a plurality of grooves 10 which are arranged in series, and the bending structure 220 is matched with the grooves 10. In this example, the curved structure 220 is curved in a semicircular shape, and the grooves 10 are also correspondingly configured in a semicircular shape, so that the curved structure 220 can be embedded in the grooves 10, and when the sliding assembly 2 slides to a proper position, the whole sliding assembly 2 is kept relatively fixed with the handle 1 by matching the curved structure 220 with one of the grooves 10.

Two or more wires 3 may be provided. In the embodiment shown in fig. 4, two overlapping wires 3 are provided, and the two wires 3 are connected by laser welding or other mechanical processing. The junction of the two wires 3 forms a siphon groove 32, and the siphon groove 32 can be filled with pigment. For example, a proper amount of ink or methylene blue is added into siphon channel 32, after the curvature of arc portion 31 reaches a proper shape, arc portion 31 is pressed onto the upper eyelid, and a mark is left on the patient's eyelid through ink or methylene blue to help the patient observe the effect of double eyelid after double eyelid operation.

As shown in fig. 5, the eyelid designer further comprises a wire protecting sleeve 4, after the wire protecting sleeve 4 is installed, the wires 3 exposed outside the handle 1 can be completely sleeved in the wire protecting sleeve 4, and the wire protecting sleeve 4 can protect and prevent dust for the wires 3 in a non-use state. Meanwhile, the metal wire protective sleeve 4 can be matched with the handle 1 and detachably connected with the handle.

Taking the embodiment containing two wires 3 shown in fig. 4 as an example, the use method of the double-eyelid designer provided by the invention comprises the following steps:

the method comprises the following steps: the metal wire protective sleeve 4 is detached, and a proper amount of ink or methylene blue is added into the siphon groove 32;

step two: the patient looks down on the eyes, and the highest point of the arc-shaped part 31 area is placed on the skin 6-8mm above the highest point of the upper eyelid margin;

step three: lightly pressing the skin of the upper eyelid, moving the position of the sliding component 2 to adjust the radian of the arc-shaped part 31, and meanwhile, enabling the eyes of the patient to look ahead to observe the form of the heavy eyelid;

step four: when the shape of the double eyelid is satisfied, the arc part 31 is pressed on the upper eyelid to complete the marking, the height of the double eyelid line is recorded, and the position of the sliding component is recorded according to the scale on the handle 1.

After the marking is finished, the patient observes the marking position, and if the patient is not satisfied with the mark, the process is repeated continuously until the patient is satisfied with the mark.

In conclusion, the double-eyelid designer provided by the invention is provided with the handle, the sliding assembly and the metal wire, and the radian of the arc-shaped part of the metal wire can be conveniently adjusted by adjusting the position of the sliding assembly, so that the double-eyelid designer is suitable for different eye types, discomfort of a patient caused by repeated adjustment is avoided, and the injury of the double-eyelid designer to an eyeball is also avoided due to the arc-shaped design. The arc-shaped part is provided with the siphon groove, so that the one-time continuous marking of the double eyelid line can be realized, and the operation is convenient, quick and efficient.
