Description

Liquid metal prosthesis and manufacture a way

As described above, the present invention relates to a prosthesis inserted into a living body hosted by a liquid metal, and more particularly, an implant, an inlay, an onlay, porcelain, a surgical prosthesis.

The liquid metal prosthesis for producing or coating a prosthesis with a liquid metal material, which has a high hardness, a resilience, elasticity and biocompatibility, and is particularly excellent in biocompatibility in medical use. It relates to a manufacturing method.

Currently, industrially used prosthetics are very important in elasticity and biocompatibility, and most of them use titanium, which is an alloy, and in addition, alloys or coatings of metal materials such as gold, silver, copper, and the like may be used.

However, the conventional medical prosthesis made of titanium has low strength, high cost, and difficulty in manufacturing, and when it is used, it is required to use materials with low human irritation, excellent biocompatibility, and smooth surface. The reality is that you are using without.

The liquid metal used as the prosthetic material of the present application has a hard crystal structure, but the liquid metal is named as liquid metal because the arrangement of atoms is very free.

Liquid metal is five times stronger than iron, three times stronger than titanium currently used as a prosthetic material, and unlike metals, it is known to have no corrosion.

In addition, it has the ability to block electromagnetic waves, and it is possible to shape the shape freely according to the mold of the mold like plastic, and because it has no direction, it has excellent toughness, high strength and ductility, and is anisotropy. It is used in various materials because of its low electrical resistance and low electrical resistance.

In addition, conventional prostheses and alloys of Ti-carbon materials return to the original crystal shape when cooled, whereas liquid metal maintains the amorphous atomic structure in the solid state, so there are no fragile parts or nodal points, and thus the strength, elasticity and biocompatibility are very high. .

In addition, it is possible to form a free shape like plastic at a high temperature and can be applied to various fields because the thickness is thin compared to the strength.

As such, the liquid metal may be used in various fields from industrial coatings to medical supplies, sporting goods, and automotive parts, and in particular, may be used as an electronic product case such as a mobile phone, a PDA, a TV, a notebook, and the like.

Usually, the process of making a prosthesis is generally known. The process of prosthetic alloy metal is performed in the form of a prosthesis to be used, and the surface thereof becomes very rough. Therefore, the liquid metal of the present invention has to undergo a complicated processing or post-treatment process. A smooth surface can be obtained without a separate process, and as described above, elasticity and biocompatibility are very good, and a complex shape such as plastic can be easily made, and thus, it is a material having the best conditions for use as a prosthetic material.

The liquid metal of the present application is basically ingot-type raw material such as zirconium copper, and all processes are performed in a vacuum state to prevent the molecular structure of the alloy from weakening.

In addition, at what temperature the raw material melts through the high frequency equipment and the rolling process determines the quality of the liquid metal.

Processes and molding methods for liquid metal prostheses include molding by means of a mold, which is the most commonly used method of injecting a liquid material into a mold in a liquid state and bulk-solidifying.

After the molding process, the products moved are processed using water jet or laser when cutting diamond because the strength of the liquid metal is too strong to be processed, which is usually cut through water jet cutting or surface processing.

Liquid metal is not only tens of times stronger than iron, titanium, and magnesium, but also has no corrosion and can be molded precisely like plastic, and is considered as an advanced new material that can replace iron, titanium, and magnesium.

Liquid metal is usually made by mixing zirconium (40 ~ 45%) with a certain amount of titanium-nickel-copper, etc., and can be formed freely like plastic even in heat of about 600 ° C.

Most of all, when the product is made by casting (die casting) method, other metal materials have rough surface of the parts, but liquid metal has a smooth outer skin like water. The material is Ansung fit.

The advantage of liquid metal is that it is not irritating to human use, has very strong resilience and elastic strength, resistant to salt and other chemical reactions, and can be manufactured in various forms.

In addition, due to the effect of the amorphous structure is transmitted to the fine vibration, there is a high strength and high efficiency of energy transfer and has the advantage of absorbing vibration or shock, there are many advantages when used as a precision machine parts.

As described above, the prosthesis is characterized by coating a liquid metal alloy or a liquid metal, which is mainly composed of liquid metal, on the surface of a prosthesis.

It is a light metal that has high strength, excellent elasticity and corrosion resistance.

It is used as a structure for industry.

In addition, since the liquid metal is excellent in chemical resistance, the liquid metal may be easily used in a reactor, a heat exchanger, or the like in the chemical industry, and thus is a very excellent material for the prosthesis of the present invention.

The liquid metal prosthesis and its manufacturing method used as the material of the prosthesis of the present invention has a low thermal expansion or thermal conductivity coefficient, so that the deformation is small during the production of the prosthesis, and the liquid metal has an excellent corrosion resistance that cannot be estimated from other materials. Oxidized liquid metal film formed on the very strong and soft, not only has a large corrosion inhibitory effect, but also has high elasticity and a good property of instant regeneration even if the film is destroyed.

The present invention relates to a prosthesis as described above, prosthesis means all the substitutes to recover when the tissue of the human body is lost, but nowadays, it mainly refers to artificial dental implants in the dentistry to reject the root of the missing tooth, rejection to the human body It is a cutting-edge procedure that restores the original function of teeth by fixing artificial teeth after planting artificial tooth roots made of titanium without any tooth.

The present application relates to a technique for manufacturing or coating a prosthesis using the liquid metal metal.

Currently, as a prosthetic material, iron is not mainly used because of rust or corrosion, and mainly titanium alloy is used. In addition, metal, such as gold, silver, copper, and other alloys or coatings are used.

The prosthesis is a medical device used in surgery or surgery, and when used, a material having low irritation and excellent biocompatibility should be used, but the current law does not place any restrictions on the material of the prosthesis.

Since the prosthesis of the liquid metal material has various good properties as described above, the prosthesis can prevent oxidation or contamination of the prosthesis or infection during human use even if stored for a long time.

As described above, the prosthesis widely used in the field of surgery or dentistry may be made of liquid metal, which is a non-toxic and biocompatible material that is harmless to the human body, or the conventional prosthesis may be alloyed or coated with the liquid metal to prevent side effects that occur when using the prosthesis. It relates to a method for producing a functional prosthesis.

In general, liquid metal exhibits very strong corrosion resistance against nitric acid, chromic acid, and aqua residing acid under high temperature and high concentration conditions.

At high temperatures, corrosion occurs to non-oxidizing acids such as hydrochloric acid and sulfuric acid. However, even when used with some oxidizing agent, corrosion resistance to such non-oxidizing acids is also greatly improved.

In addition, liquid metal exhibits excellent corrosion resistance to boiling alkaline solutions, etc., and has much higher elasticity and biocompatibility than conventional titanium prostheses.

The production cost of liquid metal is only one third of that of titanium alloy, so the material of the prosthesis of the present application has the best condition.

On the other hand, preferably, the liquid metal prosthesis used herein is characterized in that the surgical or dental prosthesis, characterized in that the prosthesis is produced and coated with a liquid metal alloy.

The coating method of the present application is wet and dry coating, and can be preferably used in both of the prosthesis of the present application. First, the wet coating process is a process of washing and rinsing the prosthesis and put it in a conventional coating tank, wherein the liquid metal (20) is preferably added in an amount of 0.001 to 10% by weight based on the total amount of the solvent substance to be coated, so that the liquid metal film is fixed on the surface of the prosthesis. It is also preferable to apply a liquid metal binder to apply a current to coat the coating.

Meanwhile, in the dry coating of the present application, the prosthetic is washed and rinsed and dried, and then, the prosthesis is put into a plasma tank to be dry coated, and the power is operated to perform vacuum in the tank and inert gas to inject liquid metal. After attaching the target, the plasma is discharged, and then the liquid metal is coated on the prosthesis.

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

To be coated.

As described above, in the present invention, the liquid metal particle 20 having the many advantages described above is stirred in the liquid metal particle at 0.001 to 10% by weight relative to the total weight% of the prosthetic material in the manufacturing process of the prosthesis of the present invention. The particle size of the injected liquid metal has a size of 0.1 to 500nm and the coating thickness of the prosthesis during coating is characterized in that the coating film is formed on the prosthesis with a thickness of 0.1nm to 200㎛ (micrometer) and preferably Nano sized liquid metal particles with respect to the total weight% of the body is characterized in that it further comprises a 0.001 to 10% by weight relative to the total weight% of the coating material of the coating portion of the prosthesis.

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 to stick to a specific surface. The most common method is to coat with silver from the rectifier.

 However, in the present invention that can not provide electricity to the substrate (substrate), the prosthesis made of synthetic resin, ceramic, or rubber material does not pass through electricity and cannot be coated by depositing a metal on it. 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: Colloidal Palladium is attached to the surface of "+" activated synthetic resin.

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 electrodeposited. In the above, the overall incorporation and coating process and composition of the prosthesis are described in detail. Liquid metal is extremely preferred for reinforcement, heat resistance, durability, and anion and far infrared emission, and the amount of incorporation is preferably 0.001 to 10% by weight based on the total weight of the prosthesis.

The density of the liquid metal is about five times that of conventional titanium steel, and the modulus of elasticity (Modulus) is at least three times higher than that of steel, which is the metal of the conventional prosthesis, and especially the temperature of -200 to 600 It has superior specific strength (strength / specific gravity) than any industrial alloy in the range, and since liquid metal (20) is about 5 times lighter than titanium, it can reduce the weight of prosthesis (3) and superconducting heat. As good as 1/2 of titanium.

In particular, conventional titanium prostheses are alloyed with iron or nickel, which causes problems such as rust or oxidation when used in the air, in humid places, underground or on the coast, and prevents and prevents rust or corrosion oxidation problems that may occur during the distribution and storage of prostheses. can do.

As it is widely used according to the physical properties of the liquid metal 20, liquid metal has high bioactivity and low elastic modulus, low resistance to physiological rejection of body fluids, and has bio-friendly properties. The present invention has been made in the present invention to produce a prosthesis having excellent lubricity and high strength to weight, excellent corrosion resistance, low elastic modulus and the like.

Thus, the prosthesis used in various fields is composed of a liquid metal 20 alloy composed mainly of liquid metal, and in order to improve surface properties based on the entire composition of the liquid metal 20, preferably, zirconium ( 6) Niobium (7) (Nb / niobium) to improve processability mainly using (Zr / zirconium), Tantalum (8) (Ta / tantalum) and Indium (9) (In / indium) to improve corrosion resistance Etc. may be added to a certain amount of liquid metal prosthesis and a method for manufacturing the liquid metal prosthesis, which is characterized in that it is a surgical or dental prosthesis, although only shown in the drawings.
