Description

Technical Field

[0001] The utility model belongs to the field of thread carving equipment, and particularly relates to a thread carving guide needle. Background Art

[0002] Thread carving is a surgical method for cosmetic enhancement, which uses dissolved medical threads (i.e. absorbable collagen threads, hereinafter referred to as protein threads) to bury in designated skin parts to achieve a firming effect. Protein threads are usually driven into the skin through a guide needle. For example, patent CN202123176313.7 discloses a thread carving guide, which opens a lead hole on the needle and inserts the protein thread into the lead hole, so that the needle can drive the protein thread into the skin. In order to facilitate the insertion of the protein thread into the lead hole and get it stuck, a wire release groove connected to the lead hole is provided on the side wall of the needle, so that the protein thread enters the lead hole through the wire release groove, and the side wall of the lead hole also begins to have a wire clamping groove to facilitate the clamping of the protein thread and prevent the protein thread from detaching from the lead hole.

[0003] The problems with the above technical solution are: different requirements for the thickness of the protein thread are different for different pulling degrees, and the fixed wire clamping groove cannot clamp protein threads of different thicknesses, and different needles need to be replaced, which is more troublesome. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a thread carving guide needle to solve the problem that the thickness requirements of the protein thread are different for different lifting degrees, and the needle head of the existing technology cannot meet the requirements of clamping protein threads of different thicknesses.

[0005] According to the embodiment of the present invention, the present invention adopts the following technical solutions:

[0021] The present invention will be further described in detail below with reference to the accompanying drawings, and specific implementation methods will be given.

[0022] like Figure 1 、 Figure 2 As shown, the thread carving guide needle comprises a needle head 1 and a handle 2 for installing the needle head 1. The end of the needle head 1 is provided with a mounting hole 11 for installing the protein thread, and the side wall of the needle head 1 is provided with a gap 12 connected to the mounting hole 11, and the gap 12 is provided for the protein thread to enter the mounting hole 11. In order to facilitate the observation of the depth of the needle head 1 inserted into the skin, the outer wall of the needle head 1 is provided with a scale line (not shown) along its axial direction. In order to avoid the tail of the protein thread being wrapped around the needle head 1 or the handle 2, the side wall of the handle 2 is fixed with a fixing ring 9 for the protein thread to pass through. Specifically, the protein thread head is inserted into the mounting hole 11 through the gap 12, and the protein thread tail is inserted into the fixing ring 9, so as to complete the connection between the protein thread and the thread carving guide needle in the present embodiment.

[0023] A first channel 10 connected to the mounting hole 11 is provided in the needle 1 along its axial direction, and a second channel 3 connected to the first channel 10 is provided in the handle 2. A limiting rod 8 is hinged in the first channel 10 or the second channel 3. One end of the limiting rod 8 extends into the handle 2, and the other end of the limiting rod 8 extends into the mounting hole 11. The end of the limiting rod 8 located in the mounting hole 11 is used to cooperate with the inner wall of the mounting hole 11 to clamp the protein thread. The limiting rod 8 is hinged in the first channel 10 or the second channel 3 to form a lever-like structure. Specifically, combined with Figure 3 As shown, the side wall of the handle 2 is connected to the adjusting rod 7 for resisting the limiting rod 8 in a radially sliding manner. The adjusting rod 7 and the notch 12 are respectively arranged on the opposite sides of the needle 1 to Figure 1 Taking the direction shown in as an example, by pressing the lower end of the limit rod 8 from the left, the upper end of the limit rod 8 can be deflected, and the protein line is located on the left side of the upper end of the limit rod 8. Therefore, as long as the lower end of the limit rod 8 is pressed from the left side, the width between the left side of the upper end of the limit rod 8 and the inner wall of the mounting hole 11 cannot be expanded, and the protein line can be clamped better.

[0024] In this embodiment, the side wall of the handle 2 is rotatably connected to a nut 6, and the nut 6 and the adjusting rod 7 are threadedly connected, so that after the protein line is located between the limiting rod 8 and the inner wall of the mounting hole 11, the adjusting rod 7 can be driven to slide by rotating the nut 6, so that the adjusting rod 7 is deflected against the limiting rod 8, thereby adjusting the distance between the end of the limiting rod 8 and the inner wall of the mounting hole 11, which is suitable for limiting protein lines of different thicknesses.

[0025] In another embodiment of the present invention, in order to facilitate the assembly and disassembly of the needle 1, the limiting rod 8 and the handle 2 (for example, disinfection), the needle 1 is detachably connected to the handle 2. Specifically, the needle 1 is directly inserted into the second channel 3 and connected to the handle 2. A socket is provided on the side wall of the needle 1, and an insertion rod 4 is threadedly connected to the handle 2. The socket is for inserting the insertion rod 4. After the needle 1 is inserted into the specified position in the second channel 3, the insertion rod 4 is rotated so that the insertion rod 4 is inserted into the socket to fix the needle 1.

[0026] The limiting rod 8 can also be detachably connected to the handle 2. Specifically, Figure 4 As shown, the end of the handle 2 is provided with a slot communicating with the second channel 3, in which a mounting rod 13 is engaged. The limiting rod 8 is hingedly connected to the mounting rod 13, with the axis of the mounting rod 13 and the axis of the limiting rod 8 being perpendicular to each other. A groove 14 is provided on the side wall of the needle 1 for the mounting rod 13 to pass through, so that after the mounting rod 13 is installed, the needle 1 can still be inserted into the second channel 3. A limiting ring 5 is fixed to the side wall of the needle 1, and the limiting ring 5 is used to abut the end of the handle 2.

[0027] During specific assembly, one end of the limiting rod 8 is inserted into the second channel 3 so that the mounting rod 13 is stuck in the card slot. Then, the needle 1 is inserted into the second channel 3. During insertion, the groove 14 is aligned with the mounting rod 13. When the limiting ring 5 moves to abut against the end of the handle 2, the needle 1 can be positioned and inserted into the specified position. The needle 1 can then be fixed by inserting the insertion rod 4 into the socket. In addition, the limiting ring 5 can also cooperate with the card slot to achieve the limited fixation of the mounting rod 13, and the cooperation between the mounting rod 13 and the groove 14 also achieves the positioning of the direction of the needle 1 inserted into the second channel 3, so that after the needle 1 is inserted into the second channel 3, the insertion rod 4 can be aligned with the socket.
