Description

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, to a UV lamp for implant surface modification treatment provided with an electrode terminal capable of stably supplying power.

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 them adhere well to the surface.

However, according to the prior art, a power supply structure having a complex structure is required to supply power to the electrodes disposed inside the lamp, and there is a problem in that stable support is difficult when thermal expansion occurs during use.

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

An embodiment of the present invention is to provide a UV lamp for implant surface modification treatment capable of supplying power while an internal electrode is exposed to the outside of a discharge container.

In addition, it is intended to provide an ultraviolet lamp for surface modification treatment in which internal electrodes and power plates are mutually elastically supported.

According to an aspect of the present invention, an ultraviolet lamp for surface modification treatment of an implant, wherein an inner electrode in which a target object is disposed, an outer electrode disposed opposite to the inner electrode, and an outer tube having the outer electrode disposed outside And, a discharge container formed in a double tube structure having an inner tube having an inner electrode disposed therein, and a connection terminal for electrically contacting the inner electrode and a power plate to which power is supplied.

In this case, the connection terminal may be provided with a connection base coupled to the internal electrode, and a connection pin extending from the connection base along a radially outer direction of the discharge container to electrically contact the power plate.

In this case, an elastic bent portion for applying an elastic force in a direction toward the power plate may be formed on the connection pin.

In this case, the elastic bent portion may include a first bent point formed at a connection portion between the connection base and the connection pin so that the connection pin is bent in a direction toward the power plate.

In this case, the elastic bent portion may further include a second bending point formed in a radially outward direction than the first bending point so that a portion of the connection pin is disposed in parallel with the power plate.

In this case, the elastic bent portion further includes a second bending point and a third bending point sequentially formed in a radially outward direction than the first bending point, and the second bending point is formed such that the connection pin extends downwardly. , The third bending point may be formed such that the connection pin is disposed parallel to the power plate.

At this time, a plurality of the connection pins are provided along the circumference of the connection base, the elastic bent portion is formed in at least two of the connection pins among the plurality of connection pins, and the connection pin formed with the elastic bent portion is the connection base It can be arranged at equal intervals along the perimeter of the

In this case, a coupling portion coupled to the internal electrode may be formed on the connection base, and the coupling portion may be formed only in a partial area of the circumference of the connection base.

In this case, the inner electrode may include an electrode base disposed in close contact with the inner circumferential surface of the inner tube, and an electrode pin extending along the circumference of the electrode base so as to be exposed to the outside of the discharge container and in electrical contact with the connection base. I can.

In this case, the electrode pins may be bent and disposed in a radially outward direction of the discharge container.

In this case, a cross-sectional reduction portion for reducing a cross-sectional area of the electrode pin in the width direction may be formed at a connection portion between the electrode base and the electrode pin.

In this case, the discharge vessel may be an excimer lamp that emits vacuum ultraviolet rays.

Since the UV lamp for implant surface modification treatment according to an embodiment of the present invention is provided with a connection terminal for electrically contacting the internal electrode and the power plate with each other, there is no need to replace the internal electrode when the connection terminal is defective, and only the connection terminal Maintenance and repair is possible simply by replacing it.

In addition, since an elastic bent portion is formed on the connection pin of the connection terminal to elastically support the power plate, it is possible to stably support during assembly and use.

In addition, even if thermal expansion occurs in the inner electrode during use, the elastic bent portion is elastically deformed to minimize such deformation, thereby maintaining a close contact between the inner electrode and the inner tube, thereby enabling constant illumination when turned on.

In addition, since the internal electrode is in electrical contact with the power plate while the internal electrode is exposed to the outside of the discharge container, power can be supplied with a simple structure.

In addition, a cross-sectional reduction portion is formed on the electrode pin, so that even if the electrode pin is bent, the close contact between the inner electrode and the inner tube can be maintained.

As shown in FIG. 1, as an ultraviolet lamp for implant surface modification treatment, an internal electrode 100 in which the object 10 is disposed inside, an external electrode 200 disposed opposite the internal electrode 100, and , The discharge vessel 300 and the inner electrode 100 formed in a double tube structure in which an outer tube 301 having an outer electrode 200 disposed on the outside, and an inner tube 302 having an inner electrode 100 disposed therein ) And the power plate 20 to which power is supplied may include a connection terminal 400 for electrically contacting each other.

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 through the connection terminal 400 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 6, 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 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 can be applied. Do.

In addition, a cylindrical external electrode 200 is provided so as to be disposed opposite to the internal electrode 100.

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

The discharge vessel 300 has a double tube structure in which an outer tube 301 having an outer electrode 200 disposed on the outside and an inner tube 302 having the inner electrode 100 disposed therein 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.

In this case, as shown in FIG. 2, since the internal electrode 100 and the power plate 20 to which power is supplied are in electrical contact with each other by the connection terminal 400, the internal electrode is The 100 does not need to be replaced, and maintenance and repair are possible simply by replacing only the connection terminal 400.

The connection terminal 400 has a plate-shaped connection base 410 extending in the circumferential direction so as to be coupled to the internal electrode 100, and extending from the connection base 410 along the radially outer direction of the discharge container 300. Thus, a connection pin 420 that is electrically contacted with the power plate 20 may be provided.

That is, the power plate 20 that supplies power from the outside is disposed along the radial direction of the discharge container 300, and if the connection pin 420 is disposed as described above, the power plate 20 and the connection pin 420 As the contact area between them increases, a stable power supply is possible.

In addition, as shown in Figure 3, the connection pin 420 is formed with an elastic bent portion 421 for applying an elastic force in the direction toward the power plate 20, this elastic bent portion 421 is a connection pin ( It is formed by deforming a part of 420). That is, as the elastic bent portion 421 is formed, the connection pin 420 elastically supports the power plate 20, so that stable support is possible during the assembly and use process.

Hereinafter, the elastic bent portion 421 will be described in detail.

3 and 4, the elastic bent portion 421 has a first bent point formed at a connection portion between the connection base 410 and the connection pin 420 so that the connection pin 420 is disposed in a radially outward direction ( 421a).

That is, as shown in (a) to (c) of Fig. 4, the first bending point 421a is such that the connection pin 420 is disposed in a radially outward direction, as described above, with the connection pin 420 The electrical contact area of the power plate 20 can be increased.

In addition, it is preferable that the ends of the connection pins 420 are bent only to the extent that they can be spaced apart from the side of the discharge vessel 300 by a predetermined distance h at the first bending point 421a.

In this way, when the power plate 20 is assembled while the end of the connection pin 420 is spaced apart from the side of the discharge container 300, the end of the connection pin 420 is a certain distance from the side of the discharge container 300. It is assembled in an elastically deformed state while being pressed to get closer. That is, when the connection pin 420 and the power plate 20 are assembled, the electrical contact between the connection pin 420 and the power plate 20 can be stably maintained by the elastic restoring force of the connection pin 420. .

Such an elastic bent portion 421 is radially outward from the first bent point 421a so that a portion of the connection pin 420 is disposed parallel to the power plate 20, as shown in FIG. 4B. A second bending point 421b formed in may be further included.

That is, an electrical contact portion disposed parallel to the power plate 20 is formed at a portion outside the radius of the connection pin 420 based on the second bending point 421b. Even when the second bending point 421b is formed in this way, as described above, it is preferable that the end of the connection pin 420 be bent only to the extent that it can be spaced apart from the side surface of the discharge vessel 300 by a certain distance h. And, when the power plate 20 is assembled in this state, the end of the connection pin 420 is assembled in an elastically deformed state while being pressed so that the end of the connection pin 420 becomes close to the side of the discharge vessel 300 by a certain distance, and the elasticity of the connection pin 420 This is because the electrical contact between the connection pin 420 and the power plate 20 can be stably maintained by the restoring force.

In addition, the elastic bent portion 421 has a second bending point 421b and a third bending point formed sequentially in a radially outward direction than the first bending point 421a, as shown in FIG. 4C. 421c) may be further included. That is, at the first bending point 421a, the connection pin 420 is bent to extend upward by a predetermined angle, and at the second bending point 421b, the connection pin 420 is bent to extend downward by a predetermined angle, and the third bending At the point 421c, the connection pin 420 is bent so as to be disposed parallel to the power plate 20.

When the power plate 20 is assembled in this state, the second bending point 421b of the connection pin 420 is in electrical contact with the power plate 20.

Even when the second bending point 421b and the third bending point 421c are formed in this way, as described above, the end of the connection pin 420 is arranged a certain distance (h) apart from the side surface of the discharge vessel 300 It is preferable to be bent only as much as possible, and when assembling the power plate 20 in this state, the end of the connection pin 420 is assembled in an elastically deformed state while being pressed so that the end of the connection pin 420 is close to the side of the discharge container 300 by a certain distance. This is because electrical contact between the connection pin 420 and the power plate 20 can be stably maintained by the elastic restoring force of the connection pin 420. In addition, since the connection pin 420 is bent a plurality of times to form a certain angle, it is possible to prevent the connection pin 420 from being completely pressed during use and thus deteriorating the elasticity.

When the elastic bent portion 421 is formed in the connection pin 420 as described above, since the connection pin 420 elastically supports the power plate 20, it is possible to stably support during assembly and use.

In addition, even if thermal expansion occurs in the internal electrode 100 during the use process, the elastic bent portion 421 is elastically deformed to minimize this deformation, thereby maintaining a close contact between the internal electrode 100 and the inner tube 302, so that it is lit. It becomes possible to produce a certain illuminance.

In addition, as shown in Fig. 3, a plurality of connection pins 420 are provided along the circumference of the connection base 410, and at least two connection pins 420 of the plurality of connection pins 420 have the aforementioned elasticity. The bent portions 421 are formed, and the connection pins 420 on which the elastic bent portions 421 are formed may be disposed at equal intervals along the circumference of the connection base 410.

When configured in this way, the internal electrode 100 and the power plate 20 are not biased to either side, and receive a uniform elastic force, thereby improving structural stability.

The connection base 410 is provided with a coupling portion coupled to the internal electrode 100, and the coupling portion may be formed only in a portion of the circumference of the connection base 410. That is, in order to couple the internal electrode 100 and the connection terminal 400, a coupling portion for coupling them to each other in the same manner as welding is formed, thereby enabling a stable coupling.

In this case, it is preferable that such a coupling part is formed only in a partial area of the circumference of the connection base 410. In the process of use, thermal expansion occurs in the internal electrode 100 and the connection terminal 400. When the coefficients of thermal expansion of the internal electrode 100 and the connection terminal 400 are different, the internal electrode 100 and the connection terminal 400 The degree of thermal expansion of is also different. In this case, if the coupling portion is formed in all regions of the connection base 410, the stress generated due to the different degree of thermal expansion may be concentrated on the coupling portion, and thus the durability of the coupling portion decreases, thereby connecting with the internal electrode 100. There may be a problem that the terminal 400 is separated. Therefore, as described above, if the coupling portion is formed only in a partial region of the connection base 410, the internal electrode 100 and the connection terminal 400 are separated from each other in the portion where the coupling portion is not formed, so that relative thermal expansion is possible and the coupling It is possible to prevent the deterioration of the durability of the negative.

In addition, the connection base 410 may be formed to have a circular cross-section, but as shown in FIG. 3, a certain area is formed to have an open arc-shaped cross-section to distribute stress due to pressing or thermal expansion during assembly and use. In addition, it is possible to prevent the occurrence of interference with the injection port for filling the discharge gas inside the discharge container 300.

In addition, as described above, the connection terminal 400 may be coupled to the internal electrode 100, but it is also possible to configure the connection terminal 400 to be coupled to the power plate 20.

In the internal electrode 100, as shown in FIGS. 5 and 6, the electrode base 110 disposed in close contact with the inner circumferential surface of the inner tube 302 and the electrode base 110 are exposed to the outside of the discharge vessel 300. An electrode pin 120 extending along the circumference and in electrical contact with the connection base 410 is provided.

The electrode base 110 is arranged in a rolled state to have a circular cross section corresponding to the inner circumferential surface of the inner tube 302, and at this time, the electrode base 110 is configured to be closely disposed on the inner circumferential surface of the inner tube 302 to discharge ultraviolet rays. Efficiency can be improved.

In addition, the electrode pins 120 are extended along the periphery of the electrode base 110, and the electrode pins 120 are exposed to the outside of the discharge vessel 300 so that they are in electrical contact with the connection base 410. By configuring, it is possible to supply power with a simple structure.

As shown in FIG. 5, the electrode pins 120 may be bent in a radially outward direction of the discharge container 300. That is, the electrode pins 120 are bent and disposed to surround the side of the discharge vessel 300.

The power plate 20 that supplies power from the outside is disposed along the radial direction of the internal electrode 100, and if the electrode pins 120 are disposed as described above, the connection base 410 and the electrode pin 120 As the contact area increases, a stable power supply becomes possible.

In addition, as shown in FIG. 5, a cross-sectional reduction portion 122 may be formed at a connection portion between the electrode base 110 and the electrode pin 120 to reduce the cross-sectional area of the electrode pin 120 in the width direction. As described above, since the inner electrode 100 is arranged in a rounded state so that the electrode base 110 is in close contact with the inner circumferential surface of the inner tube 302, the electrode pin 120 is outside the radius of the discharge container 300. It is important to bend the electrode pins 120 so that the curvature of the electrode base 110 does not change when bending toward the direction. As described above, when the cross-sectional reduction portion 122 is formed at the connection portion between the electrode base 110 and the electrode pin 120, the connection length of the electrode pin 120 formed along the circumference of the electrode base 110 is reduced. Therefore, even when the electrode pin 120 is bent, it is possible to effectively prevent the curvature of the electrode base 110 from changing, and thus, the contact state between the inner electrode and the inner tube can be kept constant.

In addition, as shown in FIG. 5, a region in which the electrode pins 120 are not provided may be formed in the circumference of the electrode base 110, thereby interfering with the inlet for filling the discharge gas into the discharge container 300. This can be prevented from occurring.

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.
