Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to an acupuncture needle for specifically enhancing the stimulation of the twirling manipulation and a manufacturing method thereof. Background Art

[0002] The twirling manipulation is one of the most commonly used manipulations in acupuncture treatment. That is, after the acupuncture needle is inserted into the acupoint, the needle is rotated alternately to the left and right repeatedly for multiple times. This manipulation is a key step to ensure the effective stimulation of acupuncture and the arrival of qi. However, for many years, acupuncture therapists have each inherited the skills of their teachers, and there are incomplete consistencies in the operation of the twirling manipulation among the needle applicators. In many medical books, there are distinctions between left rotation and right rotation in the recorded twirling manipulation. For example, "Acupuncture and Moxibustion Compendium" records the supplementation and reduction according to the cold and heat of the disease and the yin and yang of the meridians: "For treating febrile malaria by acupuncture of yang meridians, left rotation is for supplementation and right rotation is for reduction. For treating cold malaria by acupuncture of yin meridians, right rotation is for supplementation and left rotation is for reduction." Therefore, in the twirling manipulation, the operation differences of the needle applicator also have a greater impact on the acupuncture effect. If the needle applicator applies the opposite twirling direction, the acupuncture effect may be very different.

[0003] During the acupuncture process, the thickness of the needle body corresponds to the magnitude of the stimulation amount. The thicker the needle body, the greater the acupuncture stimulation amount, the greater the damage to the tissue, and the more obvious the acupuncture pain. Currently in clinical practice, in order to reduce the pain of the recipient during acupuncture, most of the acupuncture needles used are slender and smooth acupuncture needles. Although the slender and smooth needles reduce the damage to the tissue, they also reduce the acupuncture stimulation intensity, which has a certain impact on the acupuncture effect. On the other hand, the effective stimulation amount is also affected by the amplitude, frequency, and operation time of the manipulation. If the twirling angle is large, the frequency is fast, and the operation time is long, it is a large stimulation amount. However, currently many physicians pay attention to acupoint selection during acupuncture, but neglect the time and frequency of the manipulation technique, and the effective stimulation brought by the twirling manipulation cannot be guaranteed.

[0004] Currently, there are some acupuncture effect enhancement needles on the market, but basically they all generate a surface with random roughness on the needle body through physical grinding or chemical corrosion and other means to increase the stimulation amount during acupuncture. These methods are difficult to ensure that the randomly generated rough surfaces of each needle can produce good stimulation effects, and it is even more difficult to determine that they have good stimulation effects under the specific twirling manipulation technique. Summary of the Invention

[0005] The present invention is made to solve the above problems, and aims to provide an acupuncture needle for specifically enhancing the stimulation of the twirling manipulation and a manufacturing method thereof.

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the following embodiments will specifically describe the acupuncture needle for specifically enhancing the stimulation of the twirling manipulation and its manufacturing method of the present invention in conjunction with the accompanying drawings.

[0026] It should be noted here that the description of these implementation manners is used to help understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various implementation manners of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] <Example 1>

[0028] This embodiment provides an acupuncture needle for specifically enhancing the stimulation of the twirling manipulation and its manufacturing method.

[0029] Figure 1 This is the structural schematic diagram of the acupuncture needle for specifically enhancing the stimulation of the twirling manipulation in the first embodiment of the present invention.

[0030] As Figure 1 shown, the acupuncture needle 100 for specifically enhancing the stimulation of the twirling manipulation in this embodiment includes a needle body 10 and a target stimulation area 20.

[0031] The needle body 10 includes a needle tip 11, a needle shaft 12 and a needle handle 13 arranged in sequence. In this embodiment, the needle body 10 can be a stainless steel acupuncture needle with a diameter of 0.3 mm and a needle body length of 50 mm sold on the market.

[0032] The target stimulation area 20 is arranged on the circumferential side wall of the needle shaft 12 and is used to specifically enhance the stimulation effect of the twirling manipulation during acupuncture. The target stimulation area 20 is configured as a threaded surface formed on the needle shaft 12, and this threaded surface can specifically include a plurality of circumferential thread textures 21 distributed axially.

[0033] And in terms of size and position, the length of the target stimulation area 20 is 17 - 20 mm, preferably 18 mm. At the same time, the target stimulation area 20 is arranged close to the needle tip 11 and has a starting point 211 and an ending point 212. Among them, the starting point 211 is close to the needle tip 11, and the ending point 212 is far from the needle tip 11. The distance between the starting point 211 and the tip of the needle tip 11 is 1.5 - 2.5 mm, preferably 2 mm. Such a setting can avoid the needle tip 11, thereby ensuring the sharpness of the acupuncture needle during insertion, preventing the insertion from being blocked, and reducing pain.

[0034] The rotation direction of the circumferential thread texture 21 is right-handed relative to the direction from the needle tip 11 to the needle handle 13, that is, starting from the side close to the needle tip 11, forming a clockwise pattern, which can increase the effective stimulation during the counterclockwise twisting technique. The number of turns of the thread is 9 to 18, preferably 9; the thread pitch is 1 to 2 mm, preferably 1.5 mm; the starting angle of the thread is 14°-45°, preferably 45°.

[0035] During use, after the needle is inserted and the target stimulation area 20 is located at the acupuncture point, the medical staff only needs to twist the acupuncture needle counterclockwise through the needle handle 13 to apply effective stimulation to the target point on the acupuncture point fascia through the threaded surface in the target stimulation area 20, thereby effectively reducing the experience requirements for the medical staff.

[0036] Figure 2 This is a flow chart of a method for manufacturing an acupuncture needle for specifically enhancing twisting manipulation stimulation in Example 1 of the present invention.

[0037] like Figure 2 As shown, the method for preparing an acupuncture needle 100 for specifically enhancing twisting manipulation stimulation comprises the following steps:

[0038] Step S1, take a common acupuncture needle sold on the market and fix it on a CNC wire cutting machine, so that the molybdenum wire of the wire cutting machine works continuously, and the diameter of the molybdenum wire is 0.1 mm.

[0039] Step S2, programming and controlling the machine tool to align the acupuncture needle vertically with the molybdenum wire and move at a rotation speed of 360° / s and a translation speed of 1 mm / s.

[0040] Step S3, according to the texture direction of this embodiment, select the feed direction for processing, and start the processing of the aligned needle body cutting area from the side close to the needle tip. The distance between the starting point (i.e., the cutting starting point) and the tip of the needle tip is 2 mm, the cutting depth is preferably 0.01 mm, and the processing length is 18 mm, so that the thread texture is finely cut in the target stimulation area to obtain an acupuncture needle 100 for specifically enhancing twisting manipulation stimulation.

[0041] <Example 2>

[0042] This embodiment provides an acupuncture needle for specifically enhancing twisting manipulation stimulation and a method for manufacturing the same.

[0043] Figure 3 This is a schematic diagram of the structure of the second embodiment of the present invention.

[0044] like Figure 3As shown, the only difference between the acupuncture needle 200 for specifically enhancing the stimulation of the twirling manipulation provided in this embodiment and the acupuncture needle 100 for specifically enhancing the stimulation of the twirling manipulation in Embodiment 1 is that: in this embodiment, the thread direction of the target stimulation area 201 is left-handed relative to the direction from the needle tip 11 to the needle handle 13, that is, starting from the side close to the needle tip 11, a counterclockwise thread is formed, so that the acupuncture needle can increase the effective stimulation during the clockwise twirling manipulation. The rest of the structure is exactly the same as that in Embodiment 1, and the same structure is represented by the same serial number.

[0045] During use, after inserting the needle and the target stimulation area 201 is located at the acupoint, medical staff only need to twirl the acupuncture needle clockwise through the needle handle 13 to apply effective stimulation to the target on the acupoint fascia through the threaded surface in the target stimulation area 20, thereby effectively reducing the experience requirements for medical staff.

[0046] The preparation method of the acupuncture needle 200 for specifically enhancing the stimulation of the twirling manipulation is the same as that in Embodiment 1.

[0047] <Embodiment 3>

[0048] This embodiment provides an acupuncture needle for specifically enhancing the stimulation of the twirling manipulation and its manufacturing method.

[0049] Figure 4 It is a schematic structural diagram of Embodiment 3 of the present invention.

[0050] As Figure 4 shown, the only difference between the acupuncture needle 300 for specifically enhancing the stimulation of the twirling manipulation provided in this embodiment and the acupuncture needle 100 for specifically enhancing the stimulation of the twirling manipulation in Embodiment 1 is that: in this embodiment, the thread direction of the target stimulation area 202 is a two-way twist relative to the direction from the needle tip 11 to the needle handle 13, that is, starting from the side close to the needle tip 11, both clockwise and counterclockwise threads are present, so that the acupuncture needle specifically enhances the curative effect of the twirling manipulation best. The rest of the structure is exactly the same as that in Embodiment 1, and the same structure is represented by the same serial number.

[0051] Figure 5 It is a flowchart of the manufacturing method of the acupuncture needle for specifically enhancing the stimulation of the twirling manipulation in Embodiment 3 of the present invention.

[0052] As Figure 5 shown, the preparation method of the acupuncture needle 300 for specifically enhancing the stimulation of the twirling manipulation includes the following steps:

[0053] Step S1: Fix the commercially available ordinary acupuncture needle on the numerically controlled wire cutting machine tool, and make the molybdenum wire of the wire cutting machine tool work continuously. The diameter of the molybdenum wire is 0.1 mm.

[0054] Step S2: Program the machine tool to vertically align the acupuncture needle with the molybdenum wire and move it at a rotational speed of 360° / s and a translational speed of 1 mm / s.

[0055] Step S3’: Select a cutting direction for machining according to one of the two texture directions (clockwise texture + counterclockwise texture) in this embodiment, and start machining the aligned needle body cutting area from the side close to the tip of the needle. The distance between the starting point (i.e., the cutting starting point) and the tip of the needle tip is 2 mm, the cutting depth is preferably 0.01 mm, the machining length is 18 mm. After finely cutting out one kind of thread texture, return to the cutting starting position at a reverse translational speed of 1 mm / s and a rotational speed of 360° / s, so as to finely cut out another kind of thread texture, and finally obtain a double-twist threaded needle, that is, the acupuncture needle 300 for specifically enhancing the twirling manipulation stimulation.

[0056] <Example 4>

[0057] Figure 6 It is the finite element analysis result diagram adopted for design verification in Example 4 of the present invention.

[0058] As Figure 6 shown, in Example 4, by means of the computer finite element analysis method, a three-dimensional mechanical model of the acupoint fascia layer, a left-handed thread acupuncture needle model and a right-handed thread acupuncture needle model are established, and acupuncture simulation is carried out. The result shows that the effective gain stimulation of the left-handed thread and the right-handed thread on the acupoint is exactly in the opposite twirling direction. Based on this, the design and processing scheme of the twirling manipulation-specific enhanced stimulation acupuncture needle in Examples 1 to 3 is provided. It can not only reasonably select and match the texture-enhanced needles with different rotation directions to flexibly cope with various diseases, enhance the effective stimulation of human acupoints, and improve the acupuncture treatment effect of the twirling reinforcing-reducing manipulation, but also adopt the high-precision controllable needle body texture and its manufacturing method to enable the enhanced needle to have a unified needle body surface, reduce the rejection rate, and is also convenient for unified mass production with low cost.

[0059] Functions and effects of the embodiment

The threaded surface includes several circumferential thread textures distributed axially, so the target stimulation area can enhance the pulling and winding of the needle body on the acupoint connective tissue under the twirling manipulation, thereby enhancing the effective stimulation amount of the acupoint, generating a stronger biological effect, and improving the acupuncture treatment effect.

[0061] According to the manufacturing method of the acupuncture needle for specifically enhancing the stimulation of the twirling manipulation mentioned above, since this method processes the acupuncture needle through a numerically controlled wire cutting machine to obtain the acupuncture needle for specifically enhancing the stimulation of the twirling manipulation, the high-precision controllable needle body texture and its manufacturing method enable the enhanced needle to have a unified needle body surface, reduce the rejection rate, facilitate unified mass production, and have a low cost.

[0062] In addition, because the design and processing scheme of the acupuncture needle for specifically enhancing the stimulation under the twirling manipulation provided by the above embodiment is to simulate the acupuncture process under the twirling manipulation by means of the computer finite element analysis method, and is based on the result that the effective gain stimulation of the left-handed thread and the right-handed thread on the surface of the acupuncture needle obtained for the acupoints is exactly in the opposite twirling direction, the acupuncture needle of the present application can not only reasonably select and match the texture-enhanced needles with different rotation directions to flexibly cope with various diseases, enhance the effective stimulation of human acupoints, and improve the acupuncture treatment effect of the twirling reinforcing and reducing manipulations, but also adopt the high-precision controllable needle body texture and its manufacturing method to enable the enhanced needle to have a unified needle body surface, reduce the rejection rate, facilitate unified mass production, and have a low cost.
