Description

Technical Field

[0001] The utility model relates to the technical field of thread carving guide needles, in particular to a thread carving guide needle. Background Art

[0002] Thread lifting is a non-surgical cosmetic procedure that involves inserting special threads under the skin to lift the skin and improve sagging and wrinkles. The thread guide needle is an auxiliary tool used in thread lifting surgery to guide the thread to the correct position, helping the doctor to operate the thread more precisely to improve the patient's facial contours and skin firmness.

[0003] In order to prevent the thread engraving wire from slipping during the needle operation, the existing thread engraving guide needle often needs to pass a large amount of thread engraving wire through the needle hole and into the hollow needle body. Therefore, the existing thread engraving guide needle has the following defects: First, the threading operation is highly complicated, thereby reducing the efficiency of the operation; second, a large amount of threading leads to a waste of wire materials; third, when the needle body is pulled out, the wire body will follow the needle body to move a distance in the direction of breaking the skin, thereby affecting the effect of the operation. Therefore, there is an urgent need for a thread engraving guide needle to solve the existing problems. Utility Model Content

[0004] The utility model aims to provide a thread carving guide needle to solve the problems mentioned in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The basic technical solution provided by the utility model is: a thread engraving guide needle, comprising a needle tube, a card slot is provided on the needle tube, a needle core is movably connected in the needle tube, a card block, a needle and a piston are respectively fixedly connected to the needle core, the card block and the card slot are cooperatively arranged, the diameter of the needle head connecting end is larger than the diameter of the needle core, the piston is slidably connected to the needle tube, the needle tube is provided with a groove, a thread engraving line is passed through the groove, and one end of the thread engraving line is clamped in the card slot.

[0007] The principle of the basic technical solution is as follows: (1) A slot is opened through the needle tube, and the needle tube is slidably connected to the needle core, which is connected to the card block. During the needle puncture process, the needle core drives the card block to slide, thereby contacting and locking the thread engraving line inserted in the slot, and then sending the thread engraving line to the specified position; (2) After the thread engraving line is sent to the specified position, the needle tube is pulled, and the tissue embedded between the needle and the needle tube contacts the connecting end of the needle, causing it to slide in the opposite direction to the needle core. The needle core drives the card block to slide in the opposite direction, and the card block is separated from the thread engraving line. Under the resistance of the exposed barbs, the part of the thread engraving line inserted into the slot automatically separates from the slot.

[0008] The beneficial effects of the basic technical solution are: (1) Simplifying the threading operation: through the matching setting of the card slot and the card block, only the shorter wire body needs to be inserted into the card slot, and it is clamped by the buckle formed by the card block and the card slot, avoiding the complex operation of a large number of threading in the traditional method, simplifying the surgical process and improving the surgical efficiency; (2) Reducing wire waste: The traditional thread engraving guide needle requires a large amount of thread engraving wire to pass through the needle hole into the hollow needle body, while in this solution, the thread engraving wire can be directly inserted into the needle tube through the card slot, reducing the use of wire and saving The invention reduces the cost and waste, and at the same time effectively avoids the problem that a large amount of thread inside the needle remains in the body after the needle is withdrawn, which has a negative effect on the therapeutic effect of the thread outside the needle; (3) Avoiding the problem of residual thread: when the needle tube is withdrawn, because the diameter of the needle connection end is larger than the diameter of the needle core, the cell tissue is embedded in it, and the needle core drives the block to slide in the opposite direction, the thread engraving line loses the resistance of the block, and at the same time, the piston at the bottom of the needle core pushes the thread out, and the thread engraving line is separated from the slot, which prevents the inserted thread from being brought out when the needle is withdrawn, thereby improving the effectiveness of the operation.

[0009] Preferably, the contact surface between the card block and the card slot is a smooth curved surface, and the contact surface between the card slot and the card block is a smooth curved surface.

[0010] Through the above arrangement, it is prevented that the block and the slot interfere with the line engraving line and cut the line body.

[0011] Preferably, the diameter of the needle core is smaller than the inner diameter of the needle tube, and the diameter of the piston is equal to the inner diameter of the needle tube.

[0012] Through the above arrangement, the resistance of the needle core when sliding is reduced, making it easier to lock and release the card slot.

[0013] Preferably, the needle is a blunt needle or a sharp needle.

[0014] Through the above arrangement, a suitable needle can be selected according to surgical needs, thereby improving the practicality of the present invention.

[0015] Preferably, the thread engraving line is a barbed line, a smooth line or other types of lines.

[0016] Through the above settings, the appropriate thread type can be selected according to surgical needs.

[0017] Preferably, the outer wall of the needle tube is slidably connected with a sponge ring.

[0018] Through the above arrangement, the engraving line set in the groove can be better fixed during the needle insertion process, and blood stains overflowing from the skin at the needle insertion site can be absorbed and removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0026] like Figure 1-Figure 4 As shown, a thread carving guide needle comprises a needle tube 1, the outer wall of the needle tube 1 is slidably connected with a sponge ring 6, the needle tube 1 is provided with a card slot 101, a needle core 2 is movably connected inside the needle tube 1, a card block 3, a needle 4 and a piston 7 are respectively fixedly connected to the needle core 2, the card block 3 and the card slot 101 are arranged in coordination, the piston 7 is slidably connected to the needle tube 1, the contact surface between the card block 3 and the card slot 101 is a smooth curved surface, the diameter of the connecting end of the needle head 4 is larger than the diameter of the needle core 2, the diameter of the needle core 2 is smaller than the inner diameter of the needle tube 1, the diameter of the piston 7 is equal to the inner diameter of the needle tube 1, the needle head 4 is a blunt needle or a sharp needle, the needle tube 1 is provided with a groove 102, a thread carving line 5 is passed through the groove 102, one end of the thread carving line 5 is clamped in the card slot 101, and the thread carving line 5 is a barbed line, a smooth line or other types of line bodies.

[0027] The specific implementation process is as follows: Step 1: Hold the needle tube 1 and insert the thread carving line 5 into the card slot 101 a little, then use a vascular clamp to clamp the needle 4 and push it to the bottom so that the card slot 101 clamps the line body, and pulls the line body with a force parallel to the needle tube 1 and in the opposite direction of the needle 4 with an appropriate size. The body cannot fall out, that is, the locking test of the card slot 101 before puncture has passed; Step 2: Place the thread carving line 5 into the groove 102, set the sponge ring 6 on the outer wall of the needle tube 1, and slide it to a suitable position (close to the position of the card slot 101); Step 3: Use the needle 4 to puncture the skin. Due to the resistance of the needle core 2 during the puncture process, it slides into the needle tube 1, thereby driving the block 3 in the card slot 101 to approach the thread carving line 5 , and the piston 7 is also driven by the needle core 2 to slide in the direction of separation from the thread engraving line 5. The thread engraving line 5 loses the resistance of the block 3, and the piston 7 is also driven by the needle core 2 to slide in the direction of separation from the thread engraving line 5. The piston 7 pushes out the part of the thread engraving line 5 in the needle tube 1, so that the thread engraving line 5 is completely separated from the device, thereby preventing the thread body from being brought out when the needle is withdrawn, thereby improving the surgical effect.
