The present invention relates to a Han policy prepared by changing the surface properties of the Han policy to change the interaction between the human tissue and the Han policy surface when sleeping. One policy according to the present invention can enhance the physical action that allows the patient to feel a sense of gain caused by the needle operation performed by the operator after the needle is inserted into the human body.

Acupuncture is a device made to penetrate the skin, and is generally made of a metal whose strength and biological safety has been confirmed, and the conventional one policy is as shown in FIG. 1, in which acupuncture (2), stagnation (3) and needle acupuncture (4) Consists of, prepared using materials such as stone, gold, silver, copper, iron, bone and thorns. With the recent development of technology, stainless steel 304 or 316L, etc., which is hard to be broken, hard to break and harmful to human body, is used as a needle material.

Since the pain felt by a patient depends on the thickness and surface condition of commonly used needles, many existing technologies have been developed to reduce the degree of pain of patients. For example, a silicone film was applied to the needle surface to reduce friction between the needle and human tissue during needle acupuncture, and the needle surface was smoothed to reduce surface roughness. Reducing resistance reduced the pain the patient felt. In addition, as the thickness of the needle is thinner, the pain of the patient is reduced when the needle is inserted, and the needle becomes increasingly thin. The above technique is a technique applied to the production of needles, and the technique used in the needles has been introduced and used in the same manner as the conventional technology.

The purpose of using a needle is to inject a specific drug into body tissues such as blood vessels and muscles through a needle, and does not expect a therapeutic effect by inserting the needle. However, the policy is not aimed at injecting drugs, but aims at a therapeutic effect by inserting acupuncture points into specific areas such as meridians and acupuncture points. Thus, there is a fundamental difference between the purposes of inserting saliva into tissue.

In other words, unlike needles, one policy considers the physical stimulation of the needle's body tissues to be important. However, regardless of the effect of acupuncture, the needle is made similarly to the method of manufacturing a general needle that smoothes the surface of the needle for the purpose of reducing the pain felt by the patient when sleeping. In addition, depending on the condition of the saliva surface, the pain felt by the patient can be reduced, but there is no experimental result that the effect of acupuncture treatment is the same.

In contrast, studies on acupuncture and tissues (H. Langevin, 2002, Faseb) showed that connective tissue is wound on the surface of the needle by turning the needle from side to side after acupuncture, and the stimulation is effective. The results appeared. The results indicate that the adhesion between the surface of the needle and the connective tissue is important for the effect of acupuncture. That is, by changing the physical properties of the saliva surface to increase the binding between the two means that can improve the effect of acupuncture treatment. However, until now, the technology to reduce the roughness of the needle surface has been applied in the manufacture of Han-poli, which means that the research has been conducted only to reduce the bonding force between the two.

On the other hand, a technique for changing the needle surface properties, which are generally used for needle production, was to apply a chemical to the needle surface. The purpose of this technique can be divided into two types according to the application materials, such as the application of materials such as silicone (silicone) for lubrication purposes and the application of salicylic acid for antibacterial and therapeutic purposes, but these techniques The needle produced by this will reduce the binding force between the needle surface and the connective tissue.

On the other hand, it is stainless steel (stainless steel) mainly used as a general needle and a material of the policy, and SS304 and SS0316L are used a lot. They all belong to the austenitic family.

One method of reducing the surface roughness of such stainless steels is electropolishing, which is particularly well applied to SS304 and SS0316L. When electropolishing is applied to the metal to be polished in the electrolytic solution, a viscous initial oxide layer is formed on the surface of the metal by electrolysis, and a passivation film of metal oxide is formed so that the protruding surface is more bent due to the relatively curved surface. It is a technique that the metal surface becomes flat as a whole. This technique is applied to adjust the surface roughness of the stainless steel.

Another technique is the use of powerful lasers to process the surface (laser ablation), which injects a powerful laser pulse beam into the metal to instantaneously ablate the surface material to form a pattern. At this time, the depth of the pattern can be adjusted by adjusting the output of the laser. The technology is currently used for marking not only metals but also silicon wafers for semiconductor manufacturing.

On the other hand, the most widely used surface treatment method of one policy has been developed in the direction of forming the needle tip by mechanical grinding and to reduce the surface roughness. However, this technique is difficult to form directional surfaces.

1 is a schematic configuration diagram of a conventional one policy. Referring to Fig. 1, the conventional one policy 1 is composed of a needle acupuncture 2, a needle 3, and a needle acupuncture 4. As shown in FIG. Acupuncture refers to a part formed in the shape of a cone at one end of the needle, and is a part that enters the body when sleeping. Acupuncture is formed at the other end of the needle and serves as a handle that is held by the operator when sleeping. The diameter of the needle is larger than the diameter of the recession and has a form that can be easily caught by the finger. Stagnation is the part of acupuncture except acupuncture and acupuncture, and enters the body when sleeping. Considering the depth of needle acupuncture, in most cases, a portion of acupuncture and stagnation enters the human body. Therefore, until now, needle-making has been manufactured using a processing method that minimizes the roughness of the needle and the surface of the needle during manufacture.

The surface of the conventional acupuncture and stagnation is smoothly processed as shown in FIG. 2 because the needle can easily penetrate into the body tissue as described above, and can reduce the pain that the patient feels. However, in this form, the degree of physical stimulus generated by turning the needle in a specific direction after sleeping is lowered. That is, the intensity of physical stimulation, which is one of the important elements of acupuncture treatment, is lowered to reduce the degree of pain felt by the patient during acupuncture.

Accordingly, the present inventors have tried to enhance the acupuncture treatment effect by causing a change in physical properties of the saliva surface so as to enhance the binding force between the surface of the Han policy and the body tissues such as connective tissues of the human body. The present invention has been completed and the present invention has been made by expanding the effective area of the contact needle surface to improve the bonding force between them.

In addition, irrespective of the change of the effective area of the saliva surface, the present invention was completed by increasing the degree of stimulation of saliva's body tissues by increasing the chemical / physical adhesion between the two.

Accordingly, it is an object of the present invention to provide a policy made by adjusting the degree of roughness by roughening the needle surface by making a recess in the recess and adjusting the depth of the groove and the density of the groove.

It is also an object of the present invention to provide a policy prepared by applying or physical processing to change the chemical properties of the stagnation surface to increase the bonding force between the surface and body tissues.

In order to achieve the above object, in the present invention, by making a needle having a similar shape to the one policy consisting of acupuncture, stagnation and acupuncture, making a recess to roughen the surface of the needle, by adjusting the depth of the groove and the density of the groove It provides a policy manufactured by increasing the degree of roughness. In one policy according to the present invention, the positions at which the grooves are formed are any agglomeration and stagnation surfaces, and the grooves occupy any needle surface area. The direction of the grooves is also arbitrary.

In addition, the present invention is to make the physical roughness of the stagnation surface similar to the existing one policy, and to change the chemical properties of the stagnation surface to increase the bonding force between the surface and body tissues, and to provide a one policy prepared by applying or physical processing will be.

In the present invention, in order to change the chemical properties of the stagnation surface, a material such as a metal or a polymer is applied to a part of the needle surface, or mechanical processing such as mechanical polishing, laser ablation or ar sputtering is performed. Alternatively, chemical methods such as dry or wet etching can be used.

Examples of the metal used above include metal steel series such as Co-Cr alloy and titanium, which have been found to be biocompatible; And ceramic series such as alumina, zirconia, carbon, and the like. Suitable polymers include polyethylene, polyurlene, and polyurethane. As a coating method, in the case of a metal or ceramic series, electrolyte coating or plasma coating which are generally used are performed. The polymer is applied in a similar manner to the silicone coating method currently used to reduce the friction of the needle or the needle surface.

Hereinafter will be described in detail with reference to the drawings in one policy according to the present invention.

One policy according to the present invention is a needle (mantle needle) manufactured to be operated by hand; Acupuncture produced in the form of a conical tip to facilitate insertion into human tissue; And a recession formed between the acupuncture and the acupuncture and inserted into the human body, and a groove is formed in the longitudinal direction of the needle on the surface of the acupuncture and the recession.

3 is an embodiment of the present invention according to the present invention by forming a groove 13 uniformly in all parts of the stagnation 11 and the acupuncture 12, the connective tissue is better wound when turning the needle inserted into the human body It was made. The groove formed here has a direction parallel to the recession and a direction formed at any angle to the recession. Grooves formed in the direction parallel to the recession can lower the insertion strength when sleeping, thereby reducing the pain felt by the patient, and body tissues, particularly connective tissues, are better wound on the saliva when the needle is rotated after sleeping.

Figure 4 is another embodiment of the present invention according to the present invention, the grooves (11) in the recess 11 and the acupuncture 12 is formed in a non-uniform to connect the tissue is better when turning the needle inserted into the human body It was cold. The groove formed here has a direction parallel to the recession and a direction formed at any angle to the recession.

5 is an enlarged cross-sectional view of the surface of the recession and invasion according to the present invention after the groove is processed, and is a microscopic enlarged view showing a groove formed in the recession and invasion surface by a polishing method. As shown in FIG. 5, the one policy according to the present invention has a roughness higher than that of the conventional one policy in which an artificial groove is formed on the needle surface so that the surface shown in FIG. 2 is smoothly processed.

Figure 6 is another embodiment of one policy according to the present invention by forming a partial groove (15) in the recess 11 and a part of the acupuncture (12) uniformly or non-uniformly to connect the needle inserted into the human body inside the connective tissue This is better wound. The grooves 15 formed therein have a direction parallel to the recession and a direction formed at any angle to the recession.

Figure 7 is another embodiment of the present invention according to the present invention, by forming a random rough pattern (16) in some or all parts of the recession 11 and the acupuncture 12 is connected when turning the needle inserted into the human body The tissue was wound better.

In general, it is known that the therapeutic effect of acupuncture is significantly affected by the patient's sense of perspiration during acupuncture. This sense of gain is caused by acupuncture operation performed by a practitioner after the needle is inserted into the human body, and in the present invention, the benefit is produced by enhancing the physical action of the surface so that the patient feels faster than the existing one. To provide.

Therefore, one policy according to the present invention can maximize the therapeutic effect of the saliva, it is possible to apply to the symptom by forming a surface having a characteristic corresponding to the symptoms of the patient in the saliva.

In Langevin, we observed that when a needle is inserted into the human body and the needle is turned, the human tissue is dried by the needle, and the phenomenon plays a major role in the sense of gain and acupuncture. Therefore, after inserting the Han policy according to the present invention, which has a rough surface treatment than the conventional smooth needle surface, and turning the policy, the human tissue is wound more due to the increased frictional force, causing more gain. Will be.

As described above, in one policy according to the present invention, grooves or random patterns are formed in the recession and invasion sites, and the surface roughness is increased, and the physical and chemical properties of the surface are changed, thereby increasing the bonding strength with human tissues. Compared with the conventional one policy having a smooth surface or small bonding force, it could give more stimulus while reducing pain. In addition, one policy according to the present invention can increase the binding force between the surface and human tissue, in particular connective tissue (connective tissue) can be stimulated in a short time compared to the conventional one policy, thereby increasing the effect of acupuncture treatment . In particular, if a strong stimulus is needed for chronic diseases or the elderly, it was possible to give a strong stimulus by changing the acupuncture surface properties without using the coarse acupuncture pain that is severe when sleeping.
