Technical Field
[0001] The utility model relates to the technical field of instruments for cosmetic surgery, in particular to a thread sculpture embedding needle. Background Art
[0002] As a type of human plastic surgery technology, thread carving is based on the principle of using threads composed of absorbable protein and implanting them into the parts that need to be lifted. By lifting the threads, it can improve wrinkles, sagging and other phenomena. It can also work on other parts of the body to maintain an upright appearance and overall youthful skin.
[0003] During the thread sculpture surgery, the thread is inserted into the skin through a thread embedding needle. After the thread embedding is completed, it is mostly necessary to pull it out manually, which greatly reduces the efficiency of thread embedding. In addition, since the needle tip of the conventional pre-embedded needle has a sharp protrusion, it is easy to cause damage to blood vessels and nerves in the skin, subcutaneous or muscle tissue of the human body during the pulling out process, thereby causing complications.

[0026] like Figure 1-2As shown, the embodiment of the utility model provides a thread carving embedding needle, comprising a needle seat 100, a puncture needle 200 arranged on the needle seat 100, a core rod 301 and a thread feeding mechanism; the core rod 301 passes through the needle seat 100 and is inserted into the puncture needle 200, and an elastic clamping portion 302 is provided at one end thereof close to the needle tip of the puncture needle 200, a convex portion 303 is formed on the side wall of the core rod 301 located in the needle seat 100, and a return spring 304 is sleeved on the core rod 301 The upper end of the return spring 304 elastically presses against the protrusion 303, and the lower end elastically presses against the needle seat 100; the wire feeding mechanism includes a push rod 401 connected to one end of the core rod 301 away from the clamping portion 302, an elastic clamping arm 402 provided on the core rod 301, and an upper notch 403 and a lower notch 404 adapted to the free end of the elastic clamping arm 402, and the upper notch 403 and the lower notch 404 are respectively provided on the side walls of the needle seat 100.
[0027] In the embodiment of the utility model, the clamping portion 302 has a clamping state and an expanded state. When the push rod 401 is pressed to make the free end of the elastic clamping arm 402 on the core rod 301 engage with the upper notch 403, the clamping portion 302 is retracted into the puncture needle 200, and is in a clamping state under the squeezing of the tube wall of the puncture needle 200, and is used to clamp one end of the wire, while exposing the puncture needle 200 for puncture, and the other end of the wire is attached to the outer wall of the puncture needle 200; when the push rod 401 is pressed to make the free end of the elastic clamping arm 402 on the core rod 301 engage with the lower notch 404, the clamping portion 302 is exposed outside the puncture needle 200, so that the clamping portion 302 is in an expanded state, which is used to release the wire.
[0028] The thread-carving needle of the present invention adopts the above-mentioned technical solution. First, one end of the wire is inserted into the clamping part 302. Then, the elastic clamping arm 402 on the core rod 301 is pressed and engaged with the upper notch 403 under the action of the return spring 304, so that the clamping part 302 is retracted into the puncture needle 200. The clamping part 302 clamps the wire. After clamping, the rest of the wire is attached to the outer wall of the puncture needle 200. At this time, the puncture needle 200 is exposed and can be used for puncture. The puncture needle 200 penetrates into the skin, and the wire attached to the outer wall of the puncture needle 200 also follows in. After being inserted into place, the core rod 301 is pressed to make the elastic clamping arm 402 disengage from the upper notch 403 until it is engaged with the lower notch 404, so that the clamping part 302 releases the clamping of the wire, and the part of the wire outside the puncture needle 200 is clamped by the skin and muscle. As the puncture needle 200 is pulled out, the wire is pulled out of the puncture needle 200 and buried under the skin, thereby realizing fast and convenient wire processing.
[0029] In the embodiment of the utility model, the front end of the clamping portion 302 has a blunt head, which is used to play a protective role when the puncture needle 200 is pulled out, avoiding damage to surrounding tissues, blood vessels and nerves and causing complications, making the use process safer and smoother.
[0030] like Figure 1-2 As shown, in the embodiment of the utility model, an elastic reset arm 500 is provided on the outer wall of the needle seat 100, and a pressing block 501 corresponding to the lower notch 404 is provided on the inner wall of the elastic reset arm 500; a clamping block 405 is provided at the free end of the elastic clamping arm 402, and the clamping block 405 can be operably engaged with the upper notch 403 or the lower notch 404.
[0031] The thread-carving embedding needle of the present invention adopts the above-mentioned technical scheme. When the clamping block 405 is engaged with the upper notch 403, the clamping portion 302 is retracted into the puncture needle 200 to clamp the wire; when installation is required, the push rod 401 is pressed downward until the clamping block 405 is disengaged from the upper notch 403, and it performs a directional displacement movement downward until it is engaged in the lower notch 404. At this time, the clamping portion 302 extends out of the puncture needle 200, allowing the wire to enter the skin; and when re-clamping is required, it is only necessary to press the pressing block 501 on the elastic reset arm 500 to press the clamping block 405 inward. At this time, the clamping block 405 is forced to retreat inward to disengage from the lower notch 404, and performs a directional displacement movement upward under the elastic force of the reset spring 304 until it is engaged in the upper notch 403 again, thereby completing the retraction action of the clamping portion 302 and achieving the clamping of the wire.
[0032] like Figure 1-2 As shown, in the embodiment of the utility model, the bottom wall of the clamping block 405 is beveled to form a sliding surface. When the push rod 401 is pressed downward, the clamping block 405 is easy to escape from the upper notch 403, avoiding the occurrence of jamming as much as possible, making it smoother to use. The bevel angle is 30-45 degrees.
[0033] In the embodiment of the utility model, the sizes of the upper notch 403 and the lower notch 404 may be the same or different, and both only need to be greater than or equal to the size of the snap-in block 405. When the size of the upper notch 403 or the lower notch 404 is the same as the size of the snap-in block 405, the upper and lower ends of the snap-in block 405 abut against the upper and lower inner walls of the upper notch 403 or the lower notch 404 to achieve snap-in; and when the size of the upper notch 403 or the lower notch 404 is greater than the size of the snap-in block 405, the upper end of the snap-in block 405 abuts against the upper inner wall of the upper notch 403 or the lower notch 404 to achieve snap-in.
[0034] In the embodiment of the utility model, the snap-fit block 405 can be partially hidden in the upper notch 403 or the lower notch 404 , or can be exposed outside the upper notch 403 or the lower notch 404 , as long as snap-fitting can be achieved.
[0035] In the embodiment of the utility model, the push rod 401 is connected to the needle cap 600 by means of concave-convex snap fit, threaded connection, interference fit or bonding. The needle cap 600 facilitates pushing the push rod 401 to move in the needle seat 100 and is also convenient for personnel to press.
[0036] In the embodiment of the utility model, a plurality of anti-skid patterns and / or anti-skid grooves are provided on the outer peripheral surface of the needle seat 100. The cooperation of the anti-skid patterns and / or anti-skid grooves ensures stability when taking the needle seat 100 and facilitates the pressing operation.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
