DETAILED DESCRIPTION

[0039] The utility model will be further described below in combination with the embodiments.

[0040] Through Figures 1-10 It can be seen that the pull wire assembly comprises a pull wire 1, a long needle 2 and a hollow needle 4.

[0041] The pull wire 1 comprises a pull wire fixed connection section 101 and a pull wire locking pulling section 102, the pull wire fixed connection section 101 is respectively located at both sides of the pull wire 1, and the pull wire locking pulling section 102 is located at the middle position of the pull wire 1.

[0042] The pull wire locking pulling section 102 is provided with a pull thorn 10201, the number of the pull thorn 10201 is multiple, the multiple pull thorns 10201 are all arranged on the outside of the pull wire locking pulling section 102 and protrude outward, and the pull thorn 10201 can be used to pull and lock and fix the skin.

[0043] The long needle 2 comprises a long needle fixed connection section 201 and a long needle holding section 202, the long needle fixed connection section 201 is located at the front end of the long needle 2, the long needle holding section 202 is located at the rear end of the long needle 2, the inside of the long needle fixed connection section 201 is provided with a mounting hole 203, the front end of the mounting hole 203 penetrates to the outside of the most front end of the long needle fixed connection section 201, the inside dimension of the mounting hole 203 is consistent with the outside dimension of the pull wire fixed connection section 101, the pull wire fixed connection section 101 can be inserted into the inside of the mounting hole 203, and the fixed connection between the pull wire 1 and the long needle 2 is realized.

[0044] The long needle fixed connection section 201 is provided with a visible window 204, the material of the visible window 204 is made of medical transparent material, through the visible window 204, the position of the pull wire fixed connection section 101 inserted into the inside of the mounting hole 203 can be accurately observed, it is ensured that the pull wire fixed connection section 101 can be inserted to the most bottom end of the mounting hole 203, the situation that the pull wire is not inserted in place in the mounting hole 203 of the long needle 2 is avoided, and the situation that the pull wire 1 falls off from the mounting hole 203 of the long needle 2 during the movement of the long needle 2 driving the pull wire 1 in the hole of the hollow needle is avoided.

[0045] The hollow needle 4 comprises a hollow needle holding section 401 and a hollow needle puncture section 402. The hollow needle holding section 401 is located at the rear section of the hollow needle 4, and the hollow needle puncture section 402 is located at the front section of the hollow needle 4. The hollow needle puncture section 402 is detachably fixed with the hollow needle holding section 401. The length of the hollow needle 4 is less than the length of the long needle 2, which can ensure that, during the process of inserting the long needle 2 into the hollow needle 4, when the front end of the long needle 2 held by hand reaches the rear end of the hollow needle 4, the rear end of the long needle 2 has already exceeded the outer side of the groove wall of the groove 40201 located at the front end of the hollow needle puncture section 402.

[0046] By adopting the detachable fixing mode, when the hollow needle holding section 401 or the hollow needle puncture section 402 cannot be used due to problems, the hollow needle holding section 401 or the hollow needle puncture section 402 can be replaced separately, thereby saving costs and avoiding unnecessary waste.

[0047] The hollow needle holding section 401 is internally provided with a through hole 40101 penetrating along the length direction of the hollow needle 4. The hollow needle puncture section 402 is provided with a groove 40201 near the front end. An obtuse angle greater than 90 degrees is formed between the groove wall of the groove 40201 located at the front end of the hollow needle puncture section 402 and the bottom end of the groove 40201. The hollow needle puncture section 402 is internally provided with a through hole 40203 penetrating along the length direction of the hollow needle 4. The front end of the through hole 40203 communicates with the groove 40201, and the rear end of the through hole 40203 penetrates to the rear end of the hollow needle puncture section 402. The two through holes communicate with each other, and the pull wire 1 and the long needle 2 can pass through the two through holes.

[0048] When the long needle 2 passes through the two through holes of the hollow needle 4 and reaches the groove 40201, the obtuse angle formed between the groove wall of the groove 40201 located at the front end of the hollow needle puncture section 402 and the bottom end of the groove 40201 can ensure that the long needle 2 continues to smoothly slide outwards along the groove wall of the groove 40201 located at the front end of the hollow needle puncture section 402. The angle plays a certain guiding role.

[0049] The plurality of pull prongs 10201 are respectively located at the two side positions of the pull wire locking and pulling section 102. The pull prongs 10201 at the two side positions are alternately arranged along the length direction of the pull wire 1. The pull prongs 10201 are in the shape of a trapezoid. The outermost two end positions of the trapezoidal pull prongs 10201 are respectively provided with chamfers 3. By arranging the chamfers 3, the trapezoidal pull prongs 10201 can effectively pull and lock the skin and stimulate the contraction of the skin tissue, thereby realizing the normal contraction of the skin tissue and maximizing the avoidance of additional stimulation and damage to the skin tissue caused by the sharp corner structure of the outer part of the trapezoidal pull prongs 10201.

[0050] In addition, by alternately arranging the plurality of lifting needles 10201 along the length direction of the lifting wire 1, the lifting needle 10201 can avoid the situation of lifting and connecting vacancy in the process of lifting and tightening the skin, and can achieve the effect of lifting fine adjustment, improve the accuracy of lifting, and by arranging the lifting needle 10201 on both sides of the lifting wire locking and lifting section 102, the operator can select any side of the lifting needle 10201 for lifting according to the actual lifting position requirement during operation, which is convenient and fast.

[0051] If the two lifting needles 10201 are arranged symmetrically, the support width and stimulation intensity of the lifting needle 10201 on the skin will be increased, the self-shrinking ability of the skin will be reduced, and the lifting effect will be directly affected.

[0052] Secondly, the shape of the lifting needle 10201 is set to trapezoidal, which can realize two-direction lifting, thereby realizing local lifting effect, and the lifting effect is obvious, and more importantly, the structure can ensure that two-direction lifting can be realized at any position on the lifting wire locking and lifting section 102, while the shape of the lifting needle on most of the lifting wires is inverted, and the inverted lifting needle is inclined from the middle position of the lifting wire to the outside of the length direction of the lifting wire, which results in that the left and right side positions of the lifting wire can only be lifted to the corresponding outside direction, which has great limitations.

[0053] The mounting hole 203 is located at the middle position inside the long needle fixed connection section 201, the number of the visible window 204 is two, and the two visible windows 204 are symmetrically arranged on both sides of the mounting hole 203 on the long needle fixed connection section 201, so that the position of the lifting wire fixed connection section 101 inside the mounting hole 203 can be quickly observed through any visible window 204, which is convenient and fast.

[0054] The rear end of the two visible windows 204 is located at the last end position of the long needle fixed connection section 201, which can accurately check whether the lifting wire fixed connection section 101 is inserted into the bottom end position of the mounting hole 203.

[0055] The last end position of the visual window 204 is provided with an exhaust hole 205, one end of the exhaust hole 205 penetrates to the inside of the mounting hole 203, and the other end of the exhaust hole 205 penetrates to the outside of the visual window 204. During the insertion of the pull wire fixed connection section 101 into the mounting hole 203, because the pull wire fixed connection section 101 is in close contact with the mounting hole 203, air resistance will be generated in the inside of the mounting hole 203, which makes it difficult for the pull wire fixed connection section 101 to be smoothly inserted into the bottom end of the mounting hole 203. Therefore, the exhaust hole 205 is arranged at the last end position of the visual window 204. During the insertion of the pull wire fixed connection section 101 into the mounting hole 203, the air in the inside of the mounting hole 203 will be discharged outward through the exhaust hole 205, so as to ensure that the pull wire fixed connection section 101 can be smoothly inserted into the bottom end of the mounting hole 203, shorten the operation time, and improve the operation efficiency.

[0056] The outermost position of the pull wire fixed connection section 101 is provided with a chamfer 3. The chamfer 3 plays a certain guiding role in the initial stage of the insertion of the pull wire fixed connection section 101 into the mounting hole 203, further ensures that the pull wire fixed connection section 101 can be quickly and accurately inserted into the mounting hole 203, and can avoid unnecessary bumping between the pull wire fixed connection section 101 and the long needle fixed connection section 201.

[0057] The pull wire 1 can be made into a circular, oval, square or other shape according to actual use requirements.

[0058] The pull wire can be made of a material that can be absorbed by the skin according to actual use requirements.

[0059] When the pull wire assembly is used, first, the hollow needle 4 is inserted into the specified position of the skin, then the pull wire fixed connection section 101 on the pull wire 1 is inserted into the mounting hole 203 of the long needle 2, whether the pull wire fixed connection section 101 is inserted into the bottom end of the mounting hole 203 is observed through the visual window 204 on the long needle fixed connection section 201, then the long needle holding section 202 of the long needle 2 is held by hand, the long needle holding section 202 of the long needle 2 is passed through the through hole of the hollow needle 4, the pull wire 1 is passed through the through hole of the hollow needle 4, then the hollow needle 4 and the long needle 2 are taken out respectively, at this time, the pull wire fixed connection sections 101 on both sides of the pull wire 1 are located outside the skin, finally, according to the actual skin pulling requirements, the pull wire fixed connection sections 101 on both sides of the pull wire 1 are pulled respectively, and the skin part to be pulled is precisely pulled.

[0060] The length of the fixed connection section 101 of the pull wire is 1.2 cm±0.3 cm, which can facilitate the quick clamping of the fingers and easy pulling to both sides, and the operation is convenient and fast. If the length of the fixed connection section 101 of the pull wire is too short, it is difficult for the fingers to clamp it during operation, which brings trouble to the operation process. If the length of the fixed connection section 101 of the pull wire is too long, on the one hand, it causes unnecessary cost waste, and on the other hand, due to the too long length of the exposed part, it will bring interference to the operation, and the risk coefficient is high.

[0061] The hollow needle holding section 401 is externally provided with anti-skid convex strips 40102, which can increase the friction when the hand holds the hollow needle holding section 401, avoid the sliding between the hand and the hollow needle holding section 401 during operation, and bring safety hazards.

[0062] The front end position of the hollow needle puncture section 402 is provided with a circular arc surface 40202, which can reduce the resistance when the hollow needle 4 is inserted into the skin and moves in the skin, and further reduce the trauma to the skin tissue.

[0063] The angle between the groove wall at the front end position of the hollow needle puncture section 402 and the bottom end of the groove 40201 is 120°±5°, which can achieve the best effect and maximize the guarantee that the long needle 2 and the pull wire 1 can smoothly slide out of the groove 40201 at the front end position of the hollow needle puncture section 402. More importantly, the groove wall position with the angle can generate a certain friction support force on the passing long needle 2 and pull wire 1, preventing the long needle 2 or pull wire 1 from retreating.

[0064] The detachable fixing mode between the hollow needle puncture section 402 and the hollow needle holding section 401 is plug-in fixing or buckle fixing or screw fixing, so as to realize the quick disassembly of the hollow needle puncture section 402 or the hollow needle holding section 401.

[0065] The above is only a specific embodiment of the present application, which cannot limit the scope of the present application. Therefore, the replacement of equivalent components or equivalent changes and modifications made within the scope of the present application shall still fall within the scope of the present application.
