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 in which a discharge unit and a getter unit are disposed spaced apart from each other.

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.

Typically, the dental implant structure, which is an artificial tooth, consists of three structures: a fixture (fixture-artificial tooth root), abutment (abutment), and a crown (prosthetic, artificial tooth), and titanium and titanium alloy are common as the fixture material.

In an implant procedure, the implant fixture area that is 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 post-bone-forming cells to obtain 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.

However, according to the prior art, there is no distinction between the discharge part emitting UV (ultraviolet) light and the getter part for removing residual impurity gas or impurity gas that may be generated during lighting, or because they are disposed adjacent to each other, unnecessary discharge with the getter material. This occurs, and there is a problem in that the uniformity of the illuminance decreases due to the biased electric energy.

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 effectively preventing uneven illumination due to unnecessary discharge occurring inside the UV lamp, and lowering the starting voltage for implant surface modification treatment. .

According to an aspect of the present invention, an ultraviolet lamp for implant surface modification treatment, comprising: 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 on the outer side; , The inner electrode is a double tube structure with an inner tube provided on the inside, and a discharge unit to which ultraviolet rays are radiated between the inner tube and the outer tube, and a getter unit to remove residual impurity gas or impurity gas that may be generated during lighting It includes a discharge container to be formed, wherein the discharge container may be provided with a spacer so that the discharge part and the getter part are spaced apart from each other.

At this time, a first recessed surface may be formed at the boundary of the getter part so that the cross section of the discharge vessel is reduced.

In this case, the first recessed surface may be formed only on one of the inner tube or the outer tube.

In this case, the first recessed surface may be formed at the same time on the inner tube and the outer tube.

In this case, a second concave surface may be formed at one boundary of the discharge unit adjacent to the getter unit so that the cross section of the discharge container is reduced.

In this case, the second recessed surface may be formed in the outer tube, and the external electrode may have a starter extending radially inward of the outer tube along the second recessed surface.

In this case, a distance between the outer tube and the inner tube at the position where the second recessed surface is formed and processed may be formed differently according to the distance of the discharge space of the discharge container.

At this time, the distance between the outer tube and the inner tube at the position where the second recessed surface is formed and processed may be formed to satisfy the following relational expression.

[Relationship]

0.1 <y1 ≤ (a-b)/4

Where y1 is the distance between the outer tube and the inner tube at the position where the second recessed surface is formed, a is the inner diameter of the outer tube, and b is the outer diameter of the inner tube

In this case, a third recessed surface may be formed at the other side boundary of the discharge unit so that the cross section of the discharge vessel is reduced.

In this case, the distance between the outer tube and the inner tube at the position where the third recessed surface is formed and processed may be greater than the distance between the outer tube and the inner tube at the position where the second recessed surface is formed and processed. .

In the ultraviolet lamp for implant surface modification treatment according to an embodiment of the present invention, since the discharge unit and the getter unit are arranged spaced apart from each other, it is possible to effectively prevent unnecessary discharge with the getter material, and through this, electric energy is concentrated and the illumination intensity is reduced. It is possible to improve the efficiency by preventing the uniformity from deteriorating.

In addition, by forming a recessed surface at the boundary of the discharge unit to reduce the arrangement distance between the internal electrode and the external electrode, it is possible to lower the starting voltage of the ultraviolet lamp for the implant surface modification treatment.

In addition, by forming a recessed surface at the boundary of the discharge unit, the reflective film can be coated at a precise location inside the discharge container.

As shown in FIG. 1, as an ultraviolet lamp for implant surface modification treatment, an internal electrode 100 in which a target object 10 is disposed inside, an external electrode 200 disposed opposite thereto, and an internal electrode 100 ) And the external electrode 200, a discharge container 300 in which a discharge unit 310 to which ultraviolet rays are radiated and a getter unit 320 for removing residual impurity gas or impurity gas that may be generated during lighting are formed Including, at this time, the discharge unit 310 and the getter unit 320 are disposed to be spaced apart from each other.

The shape of the internal electrode 100 may be formed in a cylindrical structure, and a power supply unit (not shown) is provided to the internal electrode 100 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 is surface-modified by radiated ultraviolet rays.

As shown in FIG. 1, the internal electrode 100 is formed by weaving a metal wire in a mesh shape so that a plurality of through holes 110 can be formed. It is an example that the internal electrode 100 is woven in the form of a mesh, and a plurality of through holes 110 are formed by punching on the surface of a cylindrical structure of metal, or a plurality of cutouts on the surface of the cylindrical structure of metal. A variety of structures may be applied, such as forming a slit-shaped light transmitting part by forming a slit shape, and in particular, a plate-shaped metal material having a plurality of transmission holes 110 such as punching may be rolled into a circular shape.

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.

Inside the discharge vessel 300, a discharge space filled with a discharge gas so that ultraviolet rays are emitted is formed, and electricity between the internal electrode 100 and the external electrode 200 provided on the inside and outside of the discharge vessel 300, respectively. When energy is applied, 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 range (100 nm to 280 nm) may be used.

This 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 inner tube 302 Between the and the outer tube 301 are formed a discharge unit 310 to which ultraviolet rays are radiated and a getter unit 320 to remove residual impurity gas or impurity gas that may be generated during lighting.

In order to maintain and improve the discharge efficiency, barium as a getter material is provided in the getter unit 320 of the discharge container 300 to adsorb residual impurity gas or impurities that may be generated during lighting.

At this time, as described above, the discharge unit 310 and the getter unit 320 are disposed to be spaced apart from each other, and when the discharge unit 310 and the getter unit 320 are disposed to be spaced apart from each other, unnecessary discharge is effectively prevented. Through this, it is possible to improve the efficiency by preventing the decrease in the uniformity of the illuminance due to the biased electric energy.

In particular, a spacing part 330 is formed between the discharge part 310 and the getter part 320 so that the discharge part 310 and the getter part 320 are effectively spaced apart from each other. The spacer 330 is formed to have a predetermined length along the axial direction of the discharge container 300, and the discharge unit 310 and the getter unit 320 may be spaced apart from each other by a predetermined length through the spacer 330. There will be.

That is, in the discharge vessel 300, the discharge unit 310, the separation unit 330, and the getter unit 320 are arranged in the order. In addition, in order to more effectively prevent unnecessary discharge, the length (ℓ2) of the spacing portion 330 is preferably formed to be one or more times the length (ℓ1) of the getter portion (320).

A first concave surface 321 may be formed at the boundary of the getter unit 320 so that the cross section of the discharge vessel 300 is reduced, and the first concave surface 321 is formed to a position where the getter unit 320 is formed. It is displayed, and the operator can check the formation position of the getter part 320 through the position of the first depression surface 321. As shown in FIG. 1, the first depressed surface 321 has a first deformable surface 321a extending inward in the radial direction, and extends from the first deformed surface 321a, extending outward in the radial direction. It includes a first restoration surface (321b).

The first recessed surface 321 may be formed together when the discharge container 300 is manufactured.

In this case, the first recessed surface 321 may be formed only on either the inner tube 302 or the outer tube 301.

That is, as described above, between the inner tube 302 and the outer tube 301, the discharge unit 310, the spacer 330, and the getter unit 320 are arranged in order, and such a discharge unit 310 , The separation part 330 and the getter part 320 form respective boundaries in a manner to reduce the cross section of the discharge container 300.

In this case, the first recessed surface 321 forming the boundary of the getter part 320 may be formed by recessing a part of the outer tube 301 as shown in FIG. 1. When configured in this way, the operator can easily check the formation position of the getter part 320 through the position of the first depression surface 321.

FIG. 2 is a cross-sectional view showing an ultraviolet lamp for implant surface modification treatment according to another embodiment of the present invention. As shown in FIG. 2, the first concave surface 321 is formed by concaving a part of the inner tube 302. It is also possible to form.

3 is a cross-sectional view showing an ultraviolet lamp for implant surface modification treatment according to another embodiment of the present invention. As shown in FIG. 3, the first recessed surface 321 is an inner tube 302 and an outer tube ( It is also possible to form by simultaneously depressing 301).

In addition, a second concave surface 311 may be formed at one boundary of the discharge unit 310 adjacent to the getter unit 320 so that the cross section of the discharge container 300 is reduced. That is, the above-described spacing part 330 is formed between the first recessed surface 321 formed on the getter unit 320 and the second recessed surface 311 formed on the discharge unit 310. As shown in FIG. 1, the second depressed surface 311 is formed to extend radially outwardly from the second deformable surface 311a extending inward in the radial direction and extending from the second deformable surface 311a. It includes a second restoration surface 311b to be used.

At this time, as shown in FIG. 1, the second concave surface 311 is formed in the above-described outer tube 301, and at one end of the external electrode, the radius of the outer tube 301 along the second concave surface 311 A starter 210 extending radially inward may be formed. That is, since the starter 210 of the external electrode 200 extends radially inward of the outer tube 301 along the second recessed surface 311, the distance between the inner electrode 100 and one end of the external electrode 200 Is decreased, and as the distance between each electrode decreases, it is possible to lower the starting voltage for discharging.

At this time, the distance y1 between the outer tube 301 and the inner tube 302 at the position where the second depression surface 311 is formed and processed may be formed differently according to the distance of the discharge space of the discharge container 300. .

That is, the distance y1 between the outer tube 301 and the inner tube 302 at the position where the second recessed surface 311 is formed and processed may be formed to satisfy the following relational expression.

[Relationship]

0.1 <y1 ≤ (a-b)/4

Here, y1 is the distance between the outer tube 301 and the inner tube 302 at the position where the second recessed surface 311 is formed and processed, a is the inner diameter of the outer tube 301, and b is the inner tube 302 It is the apocryphal.

In addition, the lower limit of y1 is limited to 0.1 mm so that the discharge gas can be distributed between the getter unit 320 and the discharge unit 310, and the inner tube 302 and the outer tube are formed in the process of forming the second recessed surface 311. This is because it is the minimum distance that can prevent the welding of (301).

[Table 1]

When starting voltage is 2 kV RMS (Root Mean Square), frequency is 60 kHz,

According to the above (Table 1) experiment, the distance between the outer pipe 301 and the inner pipe 302 at the position where the second depression surface 311 was formed and processed when electric energy of a frequency of 60 kHz and a voltage of 2 kV was applied ( Depending on y1), whether or not to start the UV lamp varies. That is, the distance between the inner circumferential surface of the outer tube 301 and the outer circumferential surface of the inner tube 302 in the portion where the second depression 311 is not formed is defined as the distance of the discharge space, and is based on the distance of the discharge space. When the distance of y1 is less than 1/2 of the distance of the discharge space, it can be seen that the start of the ultraviolet lamp is smooth. At this time, y1 described in (Table 1) may define a range in detail as follows.

1) When the second depression 311 is not formed: y1 = (a-b)/2

2) When y1 is more than 1/2: (a-b)/4 <y1 <(a-b)/2

3) When y1 is less than 1/2 to more than 1/4: (a-b)/8 <y1 ≤ (a-b)/4

4) When y1 is 1/4 or less: y1 ≤ (a-b)/8

In addition, a third recessed surface 312 may be formed at the other boundary of the discharge unit 310 so that the cross section of the discharge container 300 is reduced. That is, the discharge unit 310 is formed between the above-described second concave surface 311 and the third concave surface 312. When the second recessed surface 311 and the third recessed surface 312 are formed in this way, the operator can easily check the height of the coating liquid when coating the reflective film 350, which will be described later, as well as outside the discharge unit 310. A wire (not shown) for installing the electrode 200 can be easily installed by winding it around the second and third recessed surfaces 311 and 312, and the position of the external electrode 200 can be adjusted after installation. It can be fixed effectively.

At this time, the distance y2 between the outer tube 301 and the inner tube 302 at the position where the third recessed surface 312 is formed and processed is the outer tube 301 at the position where the second recessed surface 311 is formed and processed. ) And the inner tube 302 may be formed larger than the distance y1.

In addition, as shown in FIGS. 1 to 3, a reflective film 350 is provided inside the discharge vessel 300 to reflect the ultraviolet rays so that the emitted ultraviolet rays are concentrated on the object 10, through which the amount of light The increase of is also possible.

As the reflective layer 350, silica, alumina, or the like may be used alone, or they may be appropriately mixed, and the reflective layer 350 may be formed by coating the same.

Alternatively, the reflective film 350 may be formed by depositing aluminum or by depositing aluminum and magnesium fluoride (MgF2).

In addition, the reflective film 350 may be composed of ultraviolet scattering particles including silica particles, or may be composed of a ceramic material having a high reflectance of ultraviolet rays. For example, aluminum oxide, magnesium fluoride, calcium fluoride, lithium fluoride, sodium fluoride, It may be composed of one or more particles of barium fluoride, fluoride lantern, cerium fluoride, cerium oxide, zirconium oxide, yttrium oxide, titanium oxide, magnesium oxide, and calcium oxide.

In addition, it is preferable that the above-described reflective film 350 is provided on the outer tube 301. That is, since the discharge unit 310 is formed between the inner tube 302 and the outer tube 301, the discharge efficiency is improved, and the ultraviolet rays emitted from the discharge unit 310 are not radiated to the outside, and the inner tube 302 A reflective film 350 is provided on the outer tube 301 so that it is radiated only to the inside of ), so that ultraviolet rays can be concentrated on the object 10 to be treated.
