[0034] Please refer to Figure 1 and Figure 2 A thread embedding tube needle device with scale in a preferred embodiment provided by the utility model comprises a needle sleeve 100, a sleeve 200 and a thread embedding needle core 300.

[0035] The needle sleeve 100 is provided with a first central hole 110 passing through the center, and the front end of the needle sleeve 100 is provided with a piercing portion 120, which is sharp and can pierce into human tissue; the sleeve 200 is sleeved on the outer periphery of the needle sleeve 100 and can be adjusted along the needle sleeve 100 so that the piercing portion 120 can extend or retract into the sleeve 200 and the length of the piercing portion 120 extending out of the sleeve 200 can be adjusted; the thread embedding needle core 300 is movably inserted through the first central hole 110, and the thread embedding needle core 300 can move back and forth and rotate in the first central hole 110. The rear end of the thread embedding needle core 300 is provided with a limit operating head 310 located outside the first central hole 110 and having a contour larger than the first central hole 110; wherein the outer periphery of the sleeve 200 or the needle sleeve 100 is provided with a scale 400 to measure and mark the length of the piercing portion 120 extending out of the sleeve 200.

[0036] The utility model provides a thread embedding tube needle device with a scale. During operation, the hands do not need to touch the needle sleeve 100 and the thread embedding needle core 300 to avoid contamination, and the sleeve 200 can be held. The sleeve 200 is larger than the needle sleeve 100 and the thread embedding needle core 300, which is convenient for operation. The thread embedding needle core can be held and operated by a limit operating head 310, and the operation is also more convenient. In addition, the sleeve 200 can be movably adjusted along the needle sleeve 100 so that the piercing portion 120 can extend or retract into the sleeve 200 and the length of the piercing portion 120 extending out of the sleeve 200 can be adjusted, so that the length of the piercing portion 120 extending out of the sleeve 200 can be adjusted according to the required thread embedding depth, that is, the insertion depth of the needle sleeve 100, and the scale 400 is used to measure and mark the length of the piercing portion 120 extending out of the sleeve 200, so as to achieve accurate control and adjustment of the thread embedding depth.

[0037] Reference Figures 1 to 3In some embodiments of the utility model, a threaded tube 130 is provided at the rear end of the insertion portion 120, and a threaded inner hole 210 threadedly connected to the threaded tube 130 is provided at the center of the sleeve 200, so that the relative position of the needle sleeve 100 and the sleeve 200 can be adjusted by screwing, thereby realizing the position adjustment of the sleeve 200, and the adjustment is convenient.

[0038] In order to facilitate screwing the sleeve 200 , in some embodiments of the present invention, a polygonal section 230 is provided on the outer periphery of the rear end of the sleeve 200 . The outer cross-section of the polygonal section 230 is a polygon, so that the sleeve 200 can be screwed conveniently by holding the polygonal section 230 .

[0039] Reference Figures 3 to 5 In a further embodiment of the utility model, a screwing head 140 is provided at the rear end of the piercing portion 120, and the outer peripheral contour of the screwing head 140 is larger than the threaded inner hole 210 of the sleeve 200, thereby limiting the relative position adjustment range of the sleeve 200 and the needle sleeve 100, and preventing the needle sleeve 100 from being completely embedded in the sleeve 200, which makes it difficult to adjust the relative position of the sleeve 200 and the needle sleeve 100, and the screwing head 140 is easy to hold and operate. When the relative position of the sleeve 200 and the needle sleeve 100 needs to be adjusted, the sleeve 200 can be held with one hand and the screwing head 140 can be screwed with the other hand.

[0040] Reference Figures 2 to 3 In some embodiments of the utility model, the front end of the sleeve 200 is provided with an extension portion 220 extending radially outward, so that when the front end of the sleeve 200 contacts the human skin, the extension portion 220 contacts the skin, thereby increasing the contact area with the skin and avoiding local compression and discomfort to the patient.

[0041] Reference Figure 1 to Figure 2 In some embodiments of the utility model, a threaded shaft section 320 is provided at the front end of the limiting operating head 310, and a limiting sleeve 330 is threadedly provided on the threaded shaft section 320, that is, an external thread is provided on the outer periphery of the threaded shaft section 320, and the limiting sleeve 330 is threadedly connected to the threaded shaft section 320, and the limiting sleeve 330 can be rotated to adjust the position. The limiting sleeve 330 is used to abut against the rear end of the needle sleeve 100 to limit the forward movement of the thread embedding needle core 300 relative to the needle sleeve 100, and the position can be rotated to adjust the position by the limiting sleeve 330, thereby adjusting the end point of the travel of the thread embedding needle core 300 relative to the needle sleeve 100.

[0042] During operation, the relative position of the sleeve 200 and the needle sleeve 100 is first adjusted, that is, the length of the insertion portion 120 extending out of the sleeve 200 is adjusted with reference to the scale 400. After adjustment, the thread embedding needle core 300 can be withdrawn a distance to achieve the desired position. Figure 4In the state shown, the thread is then inserted from the front end of the first central hole 110, and then the sleeve 200 is held and the insertion part 120 is inserted into the human tissue until the front end of the sleeve 200 abuts against the human skin, and finally the thread embedding needle core 300 is pushed forward until the limiting sleeve 330 abuts against the rear end of the needle sleeve 100, and the thread is embedded to a specified depth. The insertion depth of the insertion part 120 and the position of the limiting sleeve 330 relative to the needle sleeve 100 can both adjust the thread embedding depth, and the two can cooperate, and the adjustment of the limiting sleeve 330 mainly plays a fine-tuning effect.

[0043] In some embodiments of the utility model, a first connecting structure is provided at the front end of the limiting sleeve 330, and a second connecting structure is provided at the rear end of the needle sleeve 100. The first connecting structure and the second connecting structure can be detachably connected. Through the detachable connection between the first connecting structure and the second connecting structure, when the entire structure is packaged and taken out, the needle sleeve 100 and the buried thread needle core 300 can be prevented from being in a relatively movable state, which causes the other structure to fall off when one of the needle sleeve 100 and the buried thread needle core 300 is held by the hand. The detachable connection between the first connecting structure and the second connecting structure allows the needle sleeve 100 and the buried thread needle core 300 to be connected as a whole when the package is opened and taken out, and they are not easy to separate and fall off. When they are needed later, the first connecting structure and the second connecting structure can be disassembled, which is convenient to use.

[0044] Reference Figure 6 In a further embodiment of the present invention, the first connecting structure is a clamping column 331 arranged on the edge of the front end surface of the limiting sleeve 330, and the second connecting structure is a clamping sleeve 150 protruding from the outer periphery of the rear end of the needle sleeve 100. Specifically, the clamping sleeve 150 is arranged on the outer periphery of the screwing head 140, and the clamping sleeve 150 is provided with a clamping groove 151, and an opening 152 is provided on one side of the clamping groove 151. The width of the opening 152 is smaller than the diameter of the clamping column 331. The clamping column 331 can rotate with the limiting sleeve 330, so that the clamping column 331 rotates from the opening 152 to the clamping groove 151 and is tightly embraced by the clamping sleeve 150, thereby realizing the connection between the two. When disassembling, the limiting sleeve 330 is rotated to make the clamping column 331 detach from the clamping groove 151 from the opening 152, thereby realizing the unlocking of the two, so that the needle sleeve 100 and the thread embedding needle core 300 can move relatively, and the subsequent thread embedding operation can be started, and the unlocking is convenient. It is understandable that the clamping sleeve 150 can be made of metal material and has a certain elasticity, so that when the clamping column 331 is inserted into the opening 152, the opening 152 can be elastically opened.

[0045] Reference Figure 6 In a further embodiment of the utility model, outwardly expanding flared edges 153 are provided on both sides of the opening 152, so that the card column 331 can be introduced into the opening 152, reducing the position alignment requirements when the card sleeve 150 is connected to the card column 331, facilitating the connection, and reducing structural interference during the connection.

[0046] Reference Figure 2 and Figure 3 , the scale 400 is arranged on the outer wall of the sleeve 200, and the sleeve 200 is made of a transparent material, so that the length data of the piercing portion 120 extending out of the sleeve 200 can be obtained by comparing the marking line or structural contour line on the outer circumference of the needle sleeve 100 with the scale 400. For example, due to the different diameters, there is a step surface between the threaded tube 130 and the piercing portion 120. When the piercing portion 120 is retracted into the sleeve 200 and the front end is flush with the front end of the sleeve 200, the step surface is flush with the initial scale 400 on the left side. Then, the position of the sleeve 200 is adjusted so that the front end of the piercing portion 120 extends out of the sleeve 200. The extended distance is the scale 400 corresponding to the step surface. By reading the scale 400 corresponding to the step surface, the distance of the front end of the piercing portion 120 extending out of the sleeve 200 can be obtained. The sleeve 200 can be made of a transparent PP (polypropylene) material.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
