It is about needles that are widely used as a means to do this.The needle inserted into the human body is made of liquid metal material which is harmless to the human body, strong in hardness, and has excellent elasticity and resilience, which is biocompatibility and life of the needle. A method of manufacturing a liquid metal needle and a method of manufacturing the same, which can prevent side effects occurring during the procedure, and in particular, increase the electrical conductivity during the electroacupuncture, in which a needle is inserted into a human body and an electrode is connected thereto to increase electrical conductivity. will be.

The present invention relates to a needle that needles the human body as described above, and relates to a technique for producing a needle using a liquid metal having a very smooth surface.

Currently, STS 304 or 316 specified in KS D 3703 stainless steel wire type used as needle material is mainly used.In addition, it is used by alloying or coating metal materials such as gold, silver, copper, etc. Later, the silicone was applied to the surface of the needle in the final stage to make the insertion smooth and easy.

However, the silicon is often peeled off the human body when sleeping, causing edema. Since there is no separate shelf life, there is a risk of corrosion during long-term storage of the recession.

Although needles need to use materials that have less human irritation and excellent biocompatibility during hour handing, stagnation or needles or materials are used in medical methods without any restrictions.

Liquid metal used as the needle material of the present application is named as a liquid metal because the metal has a hard crystal structure, but the atomic arrangement is very free as a liquid.

Liquid metal is five times stronger than iron, three times stronger than titanium, the strongest in the world, and unlike metals, it is known to have no corrosion.

In addition, it has the ability to block electromagnetic waves, and can be freely shaped according to the mold mold like plastic, and has no directivity, and has excellent toughness, high strength and ductility, and no magnetic anisotropy. It is used in many materials because of its high resilience, elasticity and low electrical resistance.

In addition, conventional alloys return to their original crystal form upon cooling.

The needle tip 4 is completed through a polishing member (forcing), and the needle is completed through a washing process of removing the abrasive or foreign matter from the needle.

On the other hand, it is preferred to describe a method of coating the surface of the metal or synthetic resin material used in the present invention with a liquid metal, the coating method of the present application is wet and dry coating, both of the needles of the present application is preferably selected First, the wet coating process is performed by washing and rinsing the saliva, and then injecting the saliva into a conventional coating tank, wherein the liquid metal 20 is preferably 0.001 based on the total amount of the solvent substance to be coated. The liquid metal film is fixed to the surface of the needle by adding 10 wt% to the surface of the needle, and a conventional metal needle is added to a coating tank, and a liquid metal binder is added thereto to apply a current to coat the coating.

On the other hand, in the dry coating of the present application after the washing and rinsing process of the needle and dried it, the needle is put into a plasma tank to be dry coated, the power is operated to perform a vacuum inside the tank and inert gas is injected at this time After attaching the target, the plasma is discharged, and then the liquid metal is coated on the needle.

The thickness of the liquid metal particles coated on the surface of the needle is preferably characterized in that the coating to 0.1 (nm) to 200㎛ (micro).

Another preferred method for coating the liquid metal particles on the needle is a conventional volatile oil including alcohol with respect to 100 parts by weight of the total solution of the binder containing the nanonized liquid metal 20 at room temperature , 85 to 95 parts by weight of an inorganic material and 1 to 5 parts by weight of an oil and an inorganic binder including siloxane and acrylics, and 0.001 to 10 parts by weight of a liquid metal solution or powder are added, followed by agitation and drying, followed by drying to form a liquid metal particle on the needle surface. This will be laminated and coated.

As described above, the present invention is a liquid metal (20) metal having a number of the above advantages from 0.001 to the total weight percent of the material of the needle in the manufacturing process of the needle of the present invention

The liquid metal particles were stirred at 10% by weight, and the size of the particles of the liquid metal injected into the needle had a size of 0.1 to 500 nm, and the coating thickness of the needle during coating was 0.1 nm to 200 μm (micrometer). Characterized in that the coating film is formed and preferably further comprises a coating of 0.001 to 10% by weight with respect to the total weight% of the coating material of the coating portion of the nano-sized liquid metal particles of the nanoparticles relative to the total weight% of the needle body It is done.

The present invention follows a conventional coating method and because there are many types and methods of coating can not list all of them, a preferred embodiment of the present application to the first method of coating the liquid metal 20 is divided into electrolytic coating and electroless coating and electrolytic The coating uses electric current and the electroless coating is coated by chemical reactions without using electricity. In other words, coating means that metal ions receive electrons and are reduced and adhere to a specific surface. Coating is most commonly applied by using electricity from the rectifier.

However, in the present invention that can not provide electricity to the substrate (substrate), the needle made of synthetic resin, ceramics, rubber material is not electricity, so the metal is deposited on it can not be coated in this case most electroless coating or binder It is impregnated to coat the superficial body.

There are usually two methods of electroless coating, one of which is ① reduction coating ② substitution coating method. The reduction coating method is a coating method in which metal is precipitated through reduction reaction. Activates the substrate surface to "+" state. When controlling it, you will use a surfactant component.

1) Catalyst: Palladium of colloidal component is attached to the surface of activated plastic.

2) Accelerator: (Palladium) It removes Sn (Tin) which is contained in Palladium colloid and protects Pd and makes Pd Metal precipitate on the surface of synthetic resin.

3) Electroless chemical coating: Contains copper ions, ethylenethiamine tetraacetic acid (EDTA), sodium hydroxide (NaOH), and formaldehyde. Pd plays the role of catalyst, when Na OH raises the pH to 11 or higher. Aldehyde has a strong reducing effect, and electrons are generated at this time, and these electrons flow to copper ions, and copper ions are deposited on the Pd catalyst and coated.

The second substitution coating is as follows.

Substitution coating method is caused by the difference of oxidation / reduction power. Representative materials of substitution coating are Ni / Au, Ag coating and electrodeposit Ni on metal surface using the same method as electroless chemical copper coating method.

Then, when immersed in a solution containing liquid metal ions, the liquid metal ions are stronger than nickel, and the liquid metal ions forcibly take away the electrons inside the nickel without leaving the nickel metal in place. The silver is oxidized to become an ion, and the liquid metal receives electrons from nickel and is reduced to be electrodeposition. In the above, the overall incorporation and coating process and composition of the needle are described in detail. Liquid metal is extremely preferred for reinforcement, heat resistance, durability, anion and far-infrared emission, and the mixing amount is preferably 0.001 to 10% by weight relative to the total weight of the needle.

The density of the liquid metal is about five times that of conventional stainless steel, and the modulus of elasticity (Modulus) is at least three times higher than that of steel, the metal of the conventional needle, and especially -200 to 600 In the temperature range, the specific strength (strength / specific gravity) is superior to that of any industrial alloy, and the liquid metal (20) is about 5 times lighter than stainless steel, so the weight of the recession (3) can be extremely light and the heat conduction is also superior to that of stainless steel. Thermal expansion is about half that of stainless steel and is particularly useful for fire needles.

In particular, the conventional stainless steel needles are alloyed with iron or nickel, so there is a problem of rust or oxidation when used in the air or in a lot of humidity, underground or seaside, and prevents rust or corrosion oxidation problems that may occur during the distribution and storage of the needles. It can prevent.

As it is widely used according to the physical properties of the liquid metal 20, the liquid metal has a high strength and low modulus of elasticity, low resistance to the physiological rejection of body fluids, etc., has a bio-friendly characteristics, and the current liquid alloy material in sports In this application, it is possible to reduce the pain of patients during needle or foot needles with excellent lubricating power, and to produce a needle made of liquid metal material, which has high strength to weight, excellent corrosion resistance, and low modulus of elasticity. There is a purpose.
