[0002] Double eyelid surgery is also known as blepharoplasty, and is one of the most common surgeries in plastic surgery. Generally speaking, double eyelids visually increase the outline of the eye, add a three-dimensional sense to the eye, make the eye appear larger, and make the eyelashes curl upward, giving people a vivid and vivid feeling. Single eyelids have thicker eyelids and drooping eyelashes, which make the eyes appear smaller, dull and lifeless; in addition, more oriental people have single eyelids, accounting for more than 50%, so many people seek surgery. There are several types of surgical methods: buried suture double eyelid method, incision double eyelid method, suture double eyelid method / scarless eyelash curling double eyelid method and skin graft double eyelid method, etc., with buried suture method and incision method being the most commonly used.

[0027] Figure 1-5 The present invention is a schematic diagram of a blade for minimally invasive small incision reshaping of the face. Figure 1-Figure 5 In this embodiment, a blade for minimally invasive small incision facial resection includes a handheld portion 100, a slider 200, and limiting components 300 and 400.

[0028] The handheld part 100 includes a grip 110, a blade housing 120 installed on the top of the grip 110, and a connecting rod 130 connecting the grip 110 and the blade housing 120. A accommodating groove 121 is provided on the side wall of the blade housing 120. A guide groove 122 is provided on the symmetrical side wall of the accommodating groove 121. Two first fixing plates 123 are symmetrically installed on one side wall of the blade housing 120 with one of the guide grooves 122 as the center. A threaded rod 124 is rotatably connected between the two first fixing plates 123. The threaded rod 124 is connected to the blade housing 120. A first fixing plate 123 extends out of the end and is installed with a knob 125. Two second fixing plates 126 are symmetrically installed on the other side wall of the knife housing 120. A guide rod 127 is installed between the two second fixing plates 126. An anti-skid pad 111 is installed on the outer wall of the handle 110. Anti-skid protrusions 112 are installed on the side wall of the anti-skid pad 111. A circle of dense protrusions is provided on the outer wall of the knob 125. The anti-skid pad 111 cooperates with the anti-skid protrusions 112 to increase the comfort and friction when the hand grasps the handle 110.

[0029] The slider 200 is located inside the accommodating groove 121, and a blade 210 is installed on the outer wall of the slider 200. The symmetrical side walls of the slider 200 are installed with ear plates 220, and the ear plates 220 extend through the guide groove 122. A threaded hole 230 is opened on the side wall of one ear plate 220, and the threaded rod 124 rotates and penetrates the threaded hole 230. A guide hole 240 is opened on the side wall of the other ear plate 220, and the guide rod 127 penetrates the guide hole 240. When it is needed, the knob 125 is rotated to drive the threaded rod 124 to rotate. When the threaded rod 124 rotates, the ear plate 220 is pushed by the screw structure to drive the slider 200 The blade 210 slides toward the outside of the accommodating groove 121, and the distance that the slider 200 and the blade 210 extend from the opening of the accommodating groove 121 is adjusted for easy use. After use, the knob 125 is rotated in the opposite direction to drive the threaded rod 124 to reverse, and the ear plate 220 is pushed by the screw rod structure to drive the slider 200 and the blade 210 to move toward the inside of the accommodating groove 121 until the slider 200 and the blade 210 are completely retracted into the accommodating groove 121. The knife housing 120 protects the blade 210 to prevent the blade 210 from scratching the hand due to accidental touch when not in use, thereby affecting subsequent surgical operations.

[0030] The limiting assembly 300 includes a housing 310 mounted on the side wall of the knife housing 120, a slide groove 320 provided on the side wall of the housing 310, a slide plate 330 slidably connected to the inside of the slide groove 320, a spring 340 installed on the side wall of the slide plate 330, and a limiting groove 350 installed on the other side wall of the slide plate 330. The inner wall of the limiting groove 350 is provided with dense tooth grooves that cooperate with the knob 125. By pulling the slide plate 330 to slide in the slide groove 320 and squeeze the spring 340, the knob 125 moves from the limiting groove 350. 50 is separated inside, at this time, rotating knob 125 drives threaded rod 124 to rotate, adjust the position of blade 210 and slider 200, and release slider 330 after the adjustment is completed. Spring 340 rebounds and pushes slider 330 to move toward knob 125 until knob 125 is embedded in limiting groove 350, and the outer wall teeth of knob 125 and the inner wall teeth of limiting groove 350 bite each other to limit the rotation direction of knob 125 to prevent slider 200 and blade 210 from shifting due to accidental touch, which affects the accuracy of surgery.
