UV lamp for implant surface modification treatment {UV LAMP FOR IMPLANT SURFACE TREATMENT}

The present invention relates to a UV lamp for implant surface modification treatment, and more particularly, when thermal expansion occurs in a discharge vessel during the use of the lamp, it can be buffered, and an external electrode that facilitates close contact with an external heat sink is provided. It relates to an ultraviolet lamp for surface modification treatment.

Recently, the proportion of dental implants, which are artificial teeth, is increasing. The implant is attached to a fixture inserted into the pubis and serves as a tooth.

In general, the dental implant structure, which is an artificial tooth, consists of three structures: Fixture (fixture-artificial tooth root), Abutment (abutment), Crown (prosthesis, artificial tooth), and titanium and titanium alloy are common as the fixture material.

In an implant procedure, the implant fixture area inserted into the pubis needs to be completely placed in the pubis.

To this end, as a conventional technique, when UV (ultraviolet) light is irradiated on the surface of the implant, especially the fixture, the implant surface modification phenomenon due to ozone generated by UV (ultraviolet) light energy and UV (ultraviolet) light is caused by implant placement. It is explained in detail for three reasons in detail as it promotes the proliferation and adhesion function of the bone-forming cells after obtaining excellent treatment results.

First, ozone generated by UV (ultraviolet) light energy and UV (ultraviolet) light decomposes and evaporates carbon molecules attached to the implant surface so that bone-forming cells can adhere to the implant surface well.

Second, ozone generated by UV (ultraviolet) light energy and UV (ultraviolet) light changes the surface charge of the implant from negative to positive, thereby supporting negative-charged human cells and their adhesion and function. It electrostatically attracts to the implant surface so that it can be closely bonded.

Third, if the ozone generated by UV (ultraviolet) light energy and UV (ultraviolet) light increases the hydrophilicity of the implant surface, so that blood is well wetted on the implant surface, blood clots that are well formed on the implant surface are then implanted with bone-forming cells. It helps to adhere well to the surface.

These UV lamps are equipped with a heat sink for dissipating heat to the outside.The heat sink is structurally limited so that even if thermal expansion occurs in the process of using the lamp, the heat sink is structurally limited so that the part in contact with the heat sink cannot be expanded by heat. there was.

In addition, there is a problem in that heat dissipation performance is deteriorated due to poor contact between a discharge tube generating high temperature heat or an external electrode and a heat dissipation plate for dissipation.

Therefore, there is a need for improvement in these areas.

In this case, the tail of one elastic deformable member may be elastically deformed while being pressed along the radial direction of the discharge container by the head of the other elastic deformable member.

In this case, the elastically deformed elastically deformed member may be configured to have a predetermined height along the radial direction of the discharge container.

In this case, the elastically deformed elastically deformable member may be configured to have a height equal to or greater than a separation distance between the outer tube and the heat sink.

At this time, in the elastic deformable member, an inner support point for supporting the outer tube and an outer support point for supporting the heat sink are alternately formed, and a certain height is formed along the radial direction of the discharge vessel between the inner support point and the outer support point. Can be formed.

In this case, the elastic deformable member may be elastically deformed so that the height between the inner support point and the outer support point decreases when the external electrode is thermally expanded.

1 and 2, as an ultraviolet lamp for implant surface modification treatment, a discharge container 300 having a double tube structure provided with an outer tube 301 and an inner tube 302, and an object to be treated ( 10) A receiving space is formed, the inner electrode 100 is closely disposed on the inner circumferential surface of the inner tube 302, the outer electrode 200 and the outer disposed in close contact with the outer circumferential surface of the outer tube 302 A heat sink 400 provided on the outside of the electrode 200 is included, and the external electrode 200 is provided with an elastic deformation part 210 that buffers thermal expansion of the discharge container 300.

When the discharge gas is sealed so that ultraviolet rays are radiated inside the discharge container 300, and electric energy is applied between the internal electrode 100 and the external electrode 200 respectively provided inside and outside the discharge container 300 Ultraviolet rays are generated by the energy change of the discharge gas.

Discharge gases that generate excimer UV light such as Xe (wavelength 172 nm), ArF (wavelength 193 nm), KrCl (wavelength 222 nm), KrF (wavelength 248 nm), XeCl (wavelength 308 nm), and XeF (wavelength 351 nm) May be used, but a material capable of generating ultraviolet rays in the UVC wavelength band (100 nm to 280 nm) may be used.

This discharge vessel 300 has a double tube structure in which an outer tube 301 provided on the inside of the external electrode 200 and an inner tube 302 provided on the outside of the inner electrode 100 are formed, and the outer tube 301 A discharge region is formed between the and the inner tube 302 so that the above-described discharge gas may be sealed.

The shape of the internal electrode 100 may be formed in a cylindrical structure, and the internal electrode 100 is in electrical contact with the power plate 20 so as to supply external power.

An accommodation space in which the object 10, such as an implant fixture, is disposed is formed inside the internal electrode 100, and the object 10 is surface-modified by radiated ultraviolet rays.

As shown in FIGS. 1 and 2, the internal electrode 100 is formed by weaving a metal wire in a mesh shape so that a plurality of through holes 100a can be formed. It is an example that the internal electrode 100 is woven in a mesh form, and a plurality of penetration holes 100a are formed on the surface of the cylindrical structure of a metal material by punching, or a plurality of cutouts are formed on the surface of the cylindrical structure of a metal material. It is possible to apply various structures such as forming a slit-shaped light transmitting part.

The internal electrode 100, the external electrode 200, and the discharge vessel 300 are limited to a cylindrical shape for convenience of description, but are not necessarily limited to a cylindrical shape, and any cylindrical structure including a structure having a polygonal cross section Applicable.

In addition, a cylindrical external electrode 200 is provided so as to be disposed opposite to the internal electrode 100. In this case, the external electrode 200 may be formed by rolling the external electrode 200 having a planar structure into a cylindrical structure.

In addition, a heat sink 400 for discharging heat to the outside when heat is generated during use may be provided outside the external electrode 200. At least one cooling fin protruding outward along the circumferential direction of the heat sink 400 may be included, and when a plurality of such cooling fins are provided, they may be spaced apart from each other at intervals along the circumferential direction. Such cooling fins improve heat dissipation performance by increasing the contact area with the outside air.

In this case, when heat is generated in the process of using the lamp, the above-described discharge container 300 thermally expands and presses the external electrode 200 and the heat sink 400 in a radially outward direction. The heat sink 400 is formed of a metal material such as aluminum in a cylindrical structure to improve heat dissipation performance, and a plurality of cooling fins are provided along the circumference of the heat sink 400. This material and structural characteristics of the heat sink 400 Therefore, even when the discharge vessel 300 is pressurized in a radially outward direction, the heat sink 400 is not deformed and its shape is maintained. Eventually, thermal expansion of the discharge vessel 300 is limited by the heat sink 400, and thus the discharge vessel 300 ) Can be damaged.

Of course, in order to prevent such a problem from occurring, a separate clearance space may be formed between the discharge vessel 300 and the heat sink 400 so that the heat sink 400 does not limit the thermal expansion of the discharge vessel 300, but In this configuration, when the discharge container 300 is not thermally expanded, another problem of deteriorating heat dissipation performance occurs because the discharge container 300 and the heat sink 400 are separated from each other.

Therefore, in order to solve this problem, the external electrode 200 is provided with an elastic deformation portion 210 that buffers the thermal expansion of the discharge container 300. That is, if the discharge vessel 200, the external electrode 200, and the heat sink 400 are sequentially in close contact with each other based on the prior to use of the lamp, sufficient heat dissipation performance can be secured even at the beginning of the lamp use. Even if thermal expansion occurs in the container 300, the elastic deformable portion 210 of the external electrode 200 is elastically deformed to buffer such thermal expansion, so that damage to the discharge container 300 can be prevented.

As shown in FIG. 3, the elastic deformable part 210 may include a plurality of elastic deformable members 211 that are continuously arranged. That is, some elastic deformation occurs in a process in which the elastic deformation members 211 are coupled to each other in a continuous arrangement. When the elastic deformable member 211 is disposed between the outer tube 301 and the heat sink 400 in an elastically deformed state as described above, the external electrode 200 is transferred to the heat sink 400 by the force that the elastic deformable member 211 is elastically restored. ) To be able to adhere to the inside.

In addition, as described above, when thermal expansion occurs in the discharge container 300, the elastic deformable member 211 is elastically deformed to buffer it.

To this end, a head 211a, a body 211b, and a tail 211c are continuously formed in the elastic deformable member 211 along the arrangement direction of the elastic deformable member 211. In the case of FIG. 3, it is shown that the elastic deformable members 211 are arranged along the axial direction of the discharge vessel 300 and are interconnected, but are not necessarily limited to this direction. That is, the elastic deformable members 211 may be arranged to be interconnected while being arranged along the circumferential direction of the discharge container 300.

In this way, the elastic deformable members 211 are arranged and coupled to each other, and the coupling of the elastic deformable members 211 is continuous to the tail 211c of the elastic deformable member 211 disposed on one side, as shown in FIG. 4. The head 211a of the elastic deformable member 211 disposed on the other side is coupled.

That is, the tail 211c of one elastic deformable member 211 is elastically deformed while being pressed along the radial direction of the discharge container 300 by the head 211a of the other elastic deformable member 211. When the tails 211c of the elastic deformable members 211 that are continuously arranged in this way are elastically deformed while being pressed along the radial direction of the discharge vessel 300, and are disposed between the outer tube 301 and the heat sink 400, the external electrode ( 200) is to be able to be in close contact with the inner side of the heat sink 400.

In addition, when thermal expansion occurs in the discharge container 300, the tail 211c of the elastic deformable member 211, which has already been elastically deformed, is elastically restored again to buffer it.

In addition, as shown in FIG. 4, in the process of elastically deforming the tail 211c of one elastic deformable member 211, it is elastically deformed in the same direction as the head 211a of the other elastic deformable member 211, as described above. Since the head 211a and the tail 211c of the elastic deformable member 211 are elastically deformed at the same time, the external electrode 200 more firmly adheres to the inner side of the heat sink 400, and the degree of buffering it during thermal expansion can be improved. There will be.

In addition, the elastically deformed member 211 elastically deformed as described above has a predetermined height h along the radial direction of the discharge container 300. That is, the elastic deformable member 211 is formed to have a certain height (h), in particular, such an elastically deformed elastic deformable member 211 has a height equal to or greater than the separation distance between the outer tube 301 and the heat sink 400 (h ) By being formed to have a more stable support between the outer pipe 301 and the heat sink 400, and when thermal expansion occurs, it is possible to more effectively buffer such thermal expansion.

Alternatively, as shown in FIG. 5, the elastic deformable member 211 may have an inner support point 212 for supporting the outer pipe 301 and an outer support point 213 for supporting the heat sink 400 may be alternately formed. In addition, a predetermined height h may be formed between the inner support point 212 and the outer support point 213 along the radial direction of the discharge vessel 300.

That is, the inner support point 212 and the outer support point 213 are alternately formed in one elastic deformable member 211, but one elastic deformable member 211 is combined while moving in parallel with a predetermined distance. When the inner support point 212 is formed on the deformable member 211, the outer support point 213 may be formed on the other elastic deformable member 211, through which the outer pipe 301 and the heat sink 400 are more effectively By supporting it, the external electrode 200 can be in close contact with the heat sink 400.

In addition, the elastic deformable member 211 buffers thermal expansion in a manner that elastically deforms so that the height h between the inner support point 212 and the outer support point 213 decreases when the external electrode 200 is thermally expanded.

As shown in FIGS. 1 and 2, a heat transfer member 500 may be provided between the external electrode 200 and the heat sink 400. The heat transfer member 500 may be a foil such as aluminum or stainless steel. The heat transfer member 500 of this type may be partially deformed so as to be in close contact with the external electrode 200 while surrounding the external electrode 200, thereby increasing the heat dissipation area of the external electrode 200. do. In addition, when the heat radiation area of the external electrode 200 is increased in close contact with the heat sink 400 as described above, the heat radiation performance is further improved.

In addition, at least one concave surface 301a may be formed in the outer tube 301 so that the cross section of the discharge vessel 300 is reduced, and the external electrode 200 has a fixed wire surrounding the circumference of the concave surface 301a ( As 220 is provided, the external electrode can be fixed in a simple manner, and the position of the fixed external electrode 200 can be effectively fixed so that it does not move arbitrarily along the axial direction of the discharge container 300.

In addition, the above-described discharge container 300 may be an excimer lamp that emits vacuum ultraviolet rays. Vacuum Ultraviolet (VUV) is ultraviolet rays having a wavelength of 100 nm to 200 nm close to X-rays among ultraviolet rays, and their photon energy is very high, so contaminants such as viruses can be effectively removed. If the MS2 virus, which is a standard virus used when testing air purifiers, is passed through the air and then irradiated with vacuum ultraviolet rays, all viruses can be removed in about 0.026 seconds. That is, if vacuum ultraviolet rays are radiated into the air through the excimer lamp, sterilization can be performed within a short time.

Other embodiments may be easily proposed by deletion, addition, and the like, but it will be said that this is also within the scope of the present invention.
