Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a titanium alloy acupuncture needle for micro-magnetic adjustment of acupoints. Background Technology

[0002] Traditional acupuncture needles typically have a one-piece structure, which requires complete disposal after use, resulting in high consumable costs and the inability to recycle the needle handle. Some existing spliced ​​acupuncture instruments have obvious assembly gaps at the joints, making the needle body prone to loosening and rotation during treatment, and exhibiting poor coaxial stability. This instability of the mechanical structure not only affects the needle application but also increases the contact resistance between metal parts, leading to interruptions in physical signal or energy transmission.

[0003] In addition, ordinary steel acupuncture needles only provide mechanical stimulation by physically piercing the skin. The material itself does not have the characteristics of magnetic field energy storage and concentration. Traditional instruments cannot collect weak magnetic fields in the space environment and convert them into micro magnetic energy to be introduced into the human body's meridians. They lack energy regulation mechanisms targeting local biological ions and cell membrane permeability, and can only rely on a single mechanical stimulation to produce an effect.

[0004] The stimulation depth and treatment effect of traditional acupuncture operations are highly dependent on the physician's personal skills and experience. For different application needs such as superficial acupoint stimulation, routine meridian dredging and deep blockage treatment, existing instruments lack standardized size and specifications that can be accurately matched, resulting in a lack of unified physical boundary benchmarks for controlling the insertion depth. The repeatability of the treatment process and the degree of standardization of the operation are low. Summary of the Invention

[0005] This invention provides a titanium alloy acupuncture needle for acupoint micro-magnetic therapy, comprising a titanium alloy needle handle, a copper needle body, and a self-locking assembly. The titanium alloy needle handle has an axial groove and a radially connected lateral self-locking chamber. The copper needle body has an annular locking groove at its tail end, which is coaxially inserted into the groove. The self-locking assembly is located in the lateral self-locking chamber and includes a spring and a self-locking steel ball. The self-locking steel ball protrudes into the groove under the elastic force of the spring and mechanically engages with the annular locking groove of the copper needle body, forming a single-point steel ball tenon-and-mortise self-locking structure.

[0006] As a further specification of the above structure, the titanium alloy needle handle is made of TC4 medical titanium alloy, with a hemispherical blunt curved surface at the top, an anti-slip knurled structure on the outer wall, and an insulating layer on the outer surface. The copper needle body is made of TU1 high-purity oxygen-free copper, with a mirror-polished surface and a smoothly transitioned curved end away from the annular locking groove. The total length of the copper needle body is set to 55mm, 70mm, or 80mm. A sealing structure is provided on the outside of the lateral self-locking chamber. The spring and self-locking steel ball are sequentially arranged inside the lateral self-locking chamber. The sealing structure restricts the spring and self-locking steel ball from disengaging. The self-locking steel ball is made of 304 stainless steel. When the self-locking steel ball is engaged with the annular locking groove, the assembly gap between the titanium alloy needle handle and the copper needle body is 0.005mm. The axial tensile force after the titanium alloy needle handle and the copper needle body are connected is greater than or equal to 15N.

[0007] The innovative principle of this invention lies in constructing a physical link that combines composite materials and mechanical structures to transform environmental magnetic fields into conditioning energy for acupuncture treatment.

[0008] The titanium alloy needle handle serves as a carrier for enriching weak magnetic fields in space. It utilizes the low magnetic resistance and high magnetic permeability of TC4 material to collect weak magnetic fields from the environment. The titanium alloy needle handle relies on the impedance characteristics of its crystal structure to filter out stray magnetic noise in the environmental magnetic field, converting the disordered magnetic field into longitudinally oriented linear micro-magnetic energy. The insulating layer covering the outside of the titanium alloy needle handle blocks energy conduction at the hand contact point, allowing the converted micro-magnetic energy to form a stable magnetic potential energy field inside the titanium alloy needle handle to complete energy storage and locking.

[0009] The single-point steel ball tenon self-locking structure forms a coaxial, threadless connection between the titanium alloy needle handle and the copper needle body. This mechanical interlocking structure provides a stable axial connection force with an extremely small assembly gap of 0.005mm to ensure structural stability during needle insertion, while establishing a low-resistance physical contact surface between the metal parts.

[0010] The stored magnetic potential energy is transferred to the copper needle body through the low-impedance mechanical contact surface. The copper needle body utilizes the high conductivity of TU1 high-purity oxygen-free copper material and the fully mirror-polished surface to establish a conduction path with an overall conduction resistance of less than 0.03, reducing the loss of micro-magnetic energy during metal conduction. When the copper needle body is inserted into the acupoint, the micro-magnetic energy conducted inside is directionally output along the smoothly transitioned curved end of the needle tip, entering the deep layers of the human meridian. The output ordered micro-magnetic energy physically interferes with the human biomagnetic field, which is used to regulate the local bio-ion flow rate and change the cell membrane permeability, thereby achieving the effect of balancing the deviation of the meridian qi and blood magnetic field. This invention realizes the independent disassembly and replacement of needle consumables through a split self-locking structure, and superimposes a continuous and stable magnetic energy directional conduction conditioning mechanism on the basis of mechanical physical puncture function.

[0011] This invention provides a titanium alloy acupuncture needle for acupoint micro-magnetic therapy, which has the following beneficial effects: 1. This invention adopts a separate design of titanium alloy needle handle and copper needle body. The internal structure is formed by spring and self-locking steel ball to form a single-point steel ball tenon and mortise self-locking structure. This mechanical structure ensures coaxial stability during treatment under the physical conditions of 0.005mm assembly gap and axial tensile force greater than or equal to 15N, and establishes a low-impedance physical contact surface to ensure continuous energy conduction. The separate design supports independent disassembly and replacement of needle body consumables, improves the reusability of titanium alloy needle handle, and reduces the overall cost of consumables.

[0012] 2. This invention utilizes the low magnetic resistance and crystal structure impedance characteristics of TC4 medical titanium alloy to enrich and convert weak magnetic fields in space into directional micro-magnetic energy. Combined with the insulating layer covering the outer surface and the extremely low conduction resistance of the TU1 high-purity oxygen-free copper needle, a physical link is constructed from magnetic energy collection, storage to low-loss conduction. After the needle is inserted into the acupoint, the micro-magnetic energy enters the meridian through the curved end of the needle tip. On the basis of mechanical puncture function, a magnetic energy directional penetration mechanism is superimposed to change the local biological ion flow rate and realize the physical regulation of meridian qi and blood.

[0013] 3. The copper needles of this invention are available in three different lengths: 55mm, 70mm, and 80mm. They can be inserted and replaced through a self-locking assembly. The different needle sizes correspond to superficial acupoint stimulation, conventional meridian dredging, and deep cold and dampness blockage treatment, respectively. This allows micro-magnetic energy to penetrate the fascia and meridians to the corresponding depths layer by layer. This multi-size adaptation scheme reduces the dependence of treatment effects on individual techniques and improves the standardization and repeatability of the treatment process.

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0016] Example: Please see the appendix Figure 1 - Appendix Figure 2This invention provides a titanium alloy acupuncture needle for acupoint micro-magnetic therapy. The needle adopts a split tenon and mortise self-locking assembly structure. The titanium alloy acupuncture needle for acupoint micro-magnetic therapy consists of a main body and a micro self-locking accessory. The main body includes a TC4 titanium alloy energy storage self-locking needle handle and a TU1 high-purity oxygen-free copper conductive needle body. The micro self-locking accessory includes a 304 stainless steel self-locking ball and a micro compression spring.

[0017] The TC4 titanium alloy energy storage self-locking needle holder and the TU1 high-purity oxygen-free copper conduction needle body are connected by a coaxial vertical tenon-and-mortise self-locking structure. This coaxial vertical tenon-and-mortise self-locking structure has no internal threads, and the assembly and fitting accuracy reaches ±0.01mm. The assembly state is characterized by no play and no gaps. The above connection relationship provides a stable state at the mechanical level and establishes a continuous energy conduction channel.

[0018] The TC4 titanium alloy energy storage self-locking needle handle is made of TC4 medical titanium alloy, which has low magnetic resistance and high magnetic permeability. The top of the TC4 titanium alloy energy storage self-locking needle handle is provided with a hemispherical transition energy-concentrating passivation curved surface, and its outer wall is provided with an anti-slip knurled structure. In addition, the outer surface of the TC4 titanium alloy energy storage self-locking needle handle is covered with an insulating magnetic locking structure, which forms an insulating layer to prevent energy leakage by hand contact and to establish a one-way energy release channel.

[0019] The insulating layer is specifically formed using a medical-grade parylene vacuum conformal coating process, with a coating thickness of 15 μm to 30 μm. To enrich the weak magnetic field in space, the TC4 medical titanium alloy material undergoes high-frequency alternating magnetic field polarization treatment during the forming stage. The magnetic field strength of this polarization treatment is set to 0.5 T to 1.5 T, the treatment environment temperature is 20 °C to 25 °C, and the continuous treatment time is set to 15 to 30 minutes, thereby obtaining the internal micro-magnetic field induction capability.

[0020] The TU1 high-purity oxygen-free copper conductive needle body is made of TU1 high-purity oxygen-free copper material. The surface of the TU1 high-purity oxygen-free copper conductive needle body is treated with full-area mirror polishing to reduce surface roughness. The surface roughness Ra value after treatment is less than or equal to 0.04 μm. The needle tip of the TU1 high-purity oxygen-free copper conductive needle body is provided with a smooth transition ultra-micro curved surface energy release end. The smooth transition ultra-micro curved surface energy release end is specifically constructed as a parabolic transition surface. Its end fillet radius is set to 0.02 mm to 0.05 mm, and its end taper angle is set between 15 degrees and 25 degrees. The tail of the TU1 high-purity oxygen-free copper conductive needle body is provided with a standard annular locking groove.

[0021] The TC4 titanium alloy energy storage self-locking needle handle has an axial groove inside and a lateral spring ball self-locking chamber communicating with the groove radially. The miniature compression spring is made of 304 stainless steel with a wire diameter of 0.1mm to 0.15mm. The miniature compression spring and the 304 stainless steel self-locking ball are sequentially arranged inside the lateral spring ball self-locking chamber. The lateral spring ball self-locking chamber has a sealing structure on its exterior to restrict the internal components from coming out. The sealing structure is a miniature metal plug that is interference-fitted with the outer hole of the lateral spring ball self-locking chamber. The outer end face of the miniature metal plug is sealed and fixed to the titanium alloy needle handle body by laser micro-welding. The 304 stainless steel self-locking ball, under the elastic force of the miniature compression spring, forms a mechanical engagement with the standard annular locking groove at the tail of the TU1 high-purity oxygen-free copper conductive needle body, forming a single-point steel ball tenon and mortise self-locking structure.

[0022] In the above self-locking engagement state, the engagement gap of the connection part is 0.005mm. The axial tensile strength of the TC4 titanium alloy energy storage self-locking needle shank connected with the TU1 high-purity oxygen-free copper conductive needle body is greater than or equal to 15N. The single-point steel ball tenon self-locking structure supports 5000 insertion and removal cycles and maintains the durability of the mechanical structure within the above number of insertion and removal cycles.

[0023] After the TC4 titanium alloy energy storage self-locking needle handle comes into contact with the spatial magnetic field, it establishes a magnetic energy convergence path by utilizing the low magnetic resistance and high magnetic permeability characteristics of its crystal structure. Through the impedance characteristics of the titanium alloy crystal structure, the stray magnetic noise in the weak environmental magnetic field is filtered out, and the disordered magnetic field is converted into longitudinally oriented linear micro magnetic energy.

[0024] The converted micro-magnetic energy establishes a stable magnetic potential energy field inside the TC4 titanium alloy energy storage self-locking needle handle, completing the energy storage and locking process. The stored magnetic energy is transferred to the TU1 high-purity oxygen-free copper conductive needle body through the single-point steel ball tenon self-locking structure. In the above-mentioned coaxial direct insertion conductive link, the contact area of ​​the inner wall of the TC4 titanium alloy energy storage self-locking needle handle and the surface area of ​​the tail of the TU1 high-purity oxygen-free copper conductive needle body are provided with a local gold-plated conductive layer. The local gold-plated conductive layer is formed by micro-electroplating process, and its single-sided plating thickness is set to 1m to 2m to eliminate the contact impedance effect of the surface passivation film, thereby making the overall conduction resistance less than 0.03, establishing a low-loss energy transfer channel at the physical level.

[0025] When the TU1 high-purity oxygen-free copper conductive needle is inserted into the acupoint, the copper material connects to the human bioelectric field through conductive contact, forming a physical potential difference trigger condition, breaking the magnetic potential energy balance state inside the needle handle. Subsequently, micro-magnetic energy is directionally output along the ultra-micro curved energy release end and enters the human meridian. This micro-magnetic energy directional release process is used to change the local biological ion flow speed and regulate cell membrane permeability, thereby balancing the deviation of the meridian qi and blood magnetic field and clearing blockages.

[0026] The total length of the TC4 titanium alloy energy storage self-locking needle handle is set to 30mm, and its outer diameter is set to 3.2mm. The TU1 high-purity oxygen-free copper conductive needle body includes three different size specifications to adapt to different treatment scenarios. The first specification is a short needle assembly with an overall length of 55mm. This short needle assembly is used for superficial meridian conditioning and superficial acupoint stimulation.

[0027] The second specification is the medium needle assembly, with an overall length of 70mm. This medium needle assembly is used for routine meridian dredging and constitution correction. The third specification is the long needle assembly, with an overall length of 80mm. This long needle assembly is used for deep meridian penetration and treatment of stubborn cold and dampness blockages.

[0028] Working principle: The TC4 titanium alloy energy storage self-locking needle handle undergoes high-frequency alternating magnetic field polarization treatment during the molding stage, resulting in an oriented arrangement of its internal metal lattice and an orderly distribution of microscopic magnetic domains. When the needle handle is exposed to an external magnetic field, a weak potential is induced inside. The 15m to 30m medical-grade parylene insulating layer covering the outer surface of the needle handle has high dielectric strength, blocking the path of induced charge loss to the operator's hand. The charge then accumulates in the mother groove region inside the needle handle, forming a high potential energy region where electrostatic field and micro-magnetic field are superimposed.

[0029] The single-point steel ball tenon-and-mortise self-locking structure provides dynamic physical stability for the conduction of micro-electrical energy. Conventional spliced ​​needles are prone to relative displacement during needle movement, resulting in drastic fluctuations in contact surface impedance and affecting the transmission of micro-electrical signals. The micro-compression spring inside this device applies continuous radial pressure, causing the 304 stainless steel self-locking steel ball to tightly press the standard annular locking groove at the tail of the TU1 high-purity oxygen-free copper conductive needle body onto the inner wall of the mother groove. Combined with a 0.005mm assembly gap and a local micro-electroplated gold conductive layer with a thickness of 1m to 2m on the inner wall of the mother groove and the surface of the locking groove, the insulation barrier naturally formed by titanium oxide and copper oxide is eliminated. The continuous mechanical compressive stress further increases the micro-contact area between the gold plating layers, ensuring that the contact resistance between the needle handle and the needle body is always maintained at an extremely low level of less than 0.03 during dynamic needle movement. This low-impedance contact surface establishes a mechanically interference-free physical channel for the continuous transmission of micro-charge and micro-magnetic energy.

[0030] When the TU1 high-purity oxygen-free copper conductive needle penetrates the stratum corneum of the epidermis and reaches deep into the subcutaneous tissue, the needle comes into direct contact with the interstitial fluid rich in sodium, potassium, and chloride ions, forming an electrolyte conduction environment. At this time, the potential energy accumulated inside the needle handle begins to transfer to the needle body. The high-purity oxygen-free properties of the copper material and the full-area mirror-polished surface with a roughness of Ra0.04m reduce the skin effect loss during charge transfer on the metal surface, allowing energy to be concentrated and conducted along the needle body towards the needle tip.

[0031] The needle tip features a parabolic transition surface design. Based on the principle of conductor tip discharge, the charge distribution density is inversely proportional to the surface curvature radius. The 0.02mm to 0.05mm rounded corner radius and 15 to 25 degrees cone angle at the needle tip cause the charge conducted there to be highly concentrated, generating an extremely high surface charge density. This creates a localized high-intensity micro-electric field and micro-magnetic field around the needle tip. After the needle tip contacts the deep tissue of the acupoint, the copper needle body connects to the human body's bioelectric field and generates a physical potential difference, breaking the original magnetic potential energy balance state inside the needle handle. Weak charges and micro-magnetic energy are then directionally output along the ultra-micro curved surface energy release end and enter the human meridians.

[0032] The above-mentioned output process is characterized by the gradual injection of microampere-level biocharges and the penetration of magnetic field lines. The directional release of micromagnetic energy directly acts on the extracellular matrix around the needle tip, changing the local bio-ion flow rate. This physical intervention process causes changes in the ion concentration gradient across the cell membrane, thereby regulating cell membrane permeability. Changes in the state of ion channels trigger depolarization or hyperpolarization reactions of the cell resting potential, regulating the excitability of nerve endings and promoting microcirculation. During this operation cycle, the TU1 high-purity oxygen-free copper conductive needle body, as a conductive electrode deeply embedded in human tissue, maintains the micro-charge exchange between the human bioelectric field and the external environment. Through continuous physical micromagnetic action, it balances the deviation of the meridian qi and blood magnetic field, achieving the purpose of clearing blockages.
