Description

Ultraviolet irradiation apparatus for surface treatment of dental implant

The present invention relates to an ultraviolet irradiation device for surface treatment of a dental implant, and more particularly, to an ultraviolet irradiation device for surface treatment of a dental implant for hydrophilically modifying the surface of the implant to improve bone fusion with periodontal tissue. .

In general, an implant refers to a substitute that can replace human tissue when the original human tissue is lost, but dentistry refers to implanting artificial teeth. In other words, it is a technology that restores the function of a tooth by fixing an artificial tooth after planting a fixture made of a material that does not have a rejection reaction to the human body to replace the lost root, and then placing the artificial tooth in the alveolar bone from which the tooth has escaped.

In the case of a general prosthesis or denture, the surrounding teeth and bones are damaged over time, but the dental implant can prevent damage to the surrounding dental tissue and can be used stably because there are no secondary decay factors. In addition, since the dental implant has a structure substantially the same as that of a natural tooth, there is no pain or foreign body sensation in the gums, and it can be used semi-permanently if it is well managed.

Here, the dental implant is placed in the first process of implanting the fixture into the alveolar bone and the period during which the fixture is osteointegrated into the alveolar bone (3-6 months), and then the final prosthesis artificial crown (crowm). And a secondary process of fixation.

In detail, the first process includes removing the gum tissue of the portion where the tooth is missing, a multi-step drilling step of forming a perforation in which the fixture is to be placed in the alveolar bone, a fixture placement step, and a step of bonding the temporary tooth to the placed fixture. Includes.

Then, after a period of time for bone fusion after the first process, the temporary implant bound to the fixture is separated, and the regenerated gum tissue is removed around the temporary teeth, and then the dental implant is placed through the second process of fixing the final prosthesis. This is done.

On the other hand, the dental implant, in particular, the material used for the fixture should not only be made of a highly stable bio-friendly material for human biological tissues, but also should have no chemical or physiological reactivity or human rejection. In addition, it is very difficult to select an appropriate material because the mechanical strength must be high so that deformation or destruction is prevented even when repetitive loads and momentary pressure are applied during authoring.

Accordingly, although various metals and alloys have been developed as materials suitable for the fixture, titanium metals or titanium alloys are mainly used. These titanium or titanium alloys are easy to process, yet have high biocompatibility, bioinertness and high mechanical strength to human biological tissues.

At this time, the titanium and its alloy itself is an oxide film is formed on the surface to secure the stability compared to other metals, but it takes a long time to fuse the bone when implanted into the human body, and recently it is required to secure a more improved human stability than this. Accordingly, in order to compensate for these drawbacks, some technologies that can improve bone fusion by appropriately treating the surface of the fixture made of the above-described materials have been developed and applied.

In detail, the rate and quality of bone fusion are closely related to the surface composition, surface roughness and hydrophilicity of the fixture's surface properties and chemical composition. In particular, it is known that a fixture having a highly hydrophilic surface is advantageous for interaction with biological solutions, cells, and tissues. Therefore, in the past, some fixtures in which a titanium dioxide (TiO ₂ ) oxide film is coated on a titanium surface have been disclosed to improve biocompatibility while improving biocompatibility. In addition, techniques such as plasma spraying, sputtering, and ion implantation have been disclosed to coat the titanium oxide film on the surface of a fixture.

However, after the surface of the fixture was oxidized, the carbon atoms were combined and stabilized over time, and there was a problem of being converted to a hydrophobic surface in a low energy state. Due to this, when the surface of the fixture is converted to hydrophobic, the bone fusion ability is lowered when it is directly placed in the alveolar bone, and when the surface of the fixture is contaminated with organic matter, there is a serious problem of causing inflammation in the state where the fixture is placed.

Accordingly, some products including a storage container that can maintain the hydrophilicity of the surface-modified fixture for a long time have been released. However, the fixture including such a storage container has a problem in that it is expensive, thereby increasing the financial burden on the consumer. In addition, since it is necessary to use a product of a specific company, there is a problem that the choice of the consumer is very narrow even though it is expensive.

In order to solve this, some UV light irradiators for surface treatment have been disclosed that are capable of removing organic contaminants attached to the surface while modifying the surface of the fixture by irradiating ultraviolet rays after mounting the fixture inside.

However, the conventional UV irradiator for surface treatment has a problem in that implant placement cannot be rapidly performed because the fixture needs to be exposed to ultraviolet light for at least 2-3 hours for surface modification. In addition, since the fixture is heated while being exposed to ultraviolet rays for a long time, it takes more time to cool it, and there is a problem in that malfunction of an electrical equipment occurs due to high heat generated inside the apparatus. Moreover, when implanting a fixture that is not properly cooled, the tissue of the implantation site may be damaged, which further has a problem of acting as a negative factor for stable bone fusion.

In addition, the conventional surface treatment ultraviolet irradiator separates the fixture from the container in which the fixture is packaged and then attaches it to the inside of the machine, thereby increasing the time for the fixture to be exposed to the external environment, thereby causing secondary contamination. there was.

On the other hand, although some packaging containers in which the UV irradiation lamp is provided in a container portion in which the fixtures are individually packaged have been disclosed, there is a problem in that the overall cost of implant placement is increased due to the high cost of manufacturing each packaging container. In addition, when the ultraviolet irradiation lamp provided individually in the container part is defective or damaged by external factors, there is a problem in that the surface modification of the fixture is not substantially made and thus the effect of improving bone fusion is not provided.

1 to 6, the ultraviolet irradiation device 700 for surface treatment of the dental implant according to the present invention includes a housing part 770, an ultraviolet lamp part 720, a rotating jig part 730, and a rotating driving part ( 740) is provided. On the other hand, it is preferable to understand the ultraviolet irradiation device and the ultraviolet irradiation device for surface treatment of the dental implant to be described below in the same sense.

In detail, the housing part 770 includes a bottom surface part 771a, side parts 772a, 772b, 772c, 772d arranged upwardly along an outer edge of the bottom surface part 771a, and the side parts 772a, 772b, 772c, 772d), an upper surface portion 771b covering the upper side.

At this time, it is preferable that the upper surface portion 771b is provided with an opening 771c along both sides of the housing portion 770, and a door portion 773 that selectively opens and closes the opening 771c. Here, both side directions of the housing part 770 correspond to the transverse direction, which is an arrangement direction of the ultraviolet lamp part 720 and the rotating jig part 730, and this transverse direction is understood as a direction perpendicular to the gravity direction. desirable. A reforming space G is formed inside the housing part 770, and components such as the UV lamp part 720, the rotating jig part 730, and the rotating driving part 740 may be accommodated.

In addition, the side portions 772a, 772b, 772c, and 772d may be provided in various forms capable of forming a space inside the housing. For example, as shown in the figure, a portion of the side portion, that is, the front portion 772a and the rear portion 772b are integrally bent from the outer edge of the bottom surface portion 771a, but other portions, that is, both side portions 772c and 772d are separately It can be provided and assembled.

Alternatively, the side portion may be formed by bending the whole integrally upward from the outer edge of the bottom portion 771a. Moreover, the side portions may be individually provided on each side, or side portions integrally formed to correspond to the circumference of the bottom surface portion 771a may be assembled to an outer edge of the bottom surface portion 771a.

In addition, the bottom surface portion 771a may be provided as a single flat plate, divided along the lateral direction, but one side is integrally formed with the front portion 772a and the other side is integrally formed with the rear portion 772b. It may be, and such modifications are within the scope of the present invention.

In addition, the housing unit 770 may be provided with a display unit 777 capable of inputting and checking the driving state of the ultraviolet irradiation device 700. That is, it is possible to easily input driving signals of the ultraviolet lamp unit 720 and the rotation driving unit 740 through input means such as a button or a touch unit provided in the display unit 777. In addition, information such as the amount of ultraviolet irradiation of the ultraviolet lamp unit 720, the elapsed discharge time, the internal temperature of the reforming space G, and the rotational speed of the rotary driving unit 740 may be displayed through the display unit 777. have. Accordingly, since the operator can easily check it visually, the usability can be remarkably improved.

On the other hand, the ultraviolet lamp portion 720 is preferably arranged in the transverse direction inside the reforming space (G) so that the ultraviolet light is irradiated to the outer surface side. Here, the UV lamp unit 720 is provided in a vacuum pressure state filled with a discharge gas inside a container made of quartz, but is provided with an excimer lamp provided with a discharge electrode inside the container. This is preferred.

In detail, the discharge gas may be provided with a halogen gas such as fluorine or chlorine or a gas such as xenon or krypton. In addition, the discharge electrode may be provided in the form of a rod, spring, pipe or conductive tape. These discharge electrodes are conductive materials such as aluminum, aluminum alloys, duralumin, copper and copper alloys, conductive materials such as silver paste, indium tin oxide (ITO), and aluminum tin oxide (ATO), and stainless steel with excellent resilience. It may be composed of any one selected from alloy steel such as steel.

At this time, in the excimer lamp, excimer molecules (excited molecules) are formed as the discharge gas filled in a vacuum pressure state in the container is discharged by the electric force formed at the discharge electrode. Then, when the excimer molecule transitions to the ground state, it emits ultraviolet rays having a predetermined wavelength.

Therefore, in the ultraviolet irradiation device 700 of the present invention, since the surface of the object to be modified is modified with hydrophilicity through the ultraviolet light irradiated from the excimer lamp, the bone fusion ability can be remarkably improved. In addition, disinfection or removal of organic substances remaining on the surface of the reformed object is also performed at the same time, so that hygiene can be significantly improved. At this time, the modified object is preferably understood as a dental implant that requires surface modification to improve bone fusion ability with the alveolar bone, and implants such as a fixture (f) or abutment may be included therein. .

At this time, the excimer lamp may be irradiated with far ultraviolet rays, especially vacuum ultraviolet rays, in the UV-C range having a wavelength of 100 to 200 nm inside the vessel under vacuum pressure. The vacuum ultraviolet rays are emitted in a large amount in a vacuum pressure state, and the amount of light is abundant, and since the high energy of a short wavelength is obtained, the surface of the reformed object can be quickly modified in a short time. Accordingly, the present invention can provide good surface modification results while rapid surface modification is performed within about 5 to 10 minutes, compared to the conventional method in which surface modification using ultraviolet rays takes 2 to 3 hours or more.

In addition, far-infrared rays in the UV-C range having a wavelength of 200 to 280 nm pass through the container and are irradiated toward the modified object. Accordingly, the oxygen molecules around the reformed object are converted into an excited state while the outer electrons are excited through an energy impact exceeding the binding energy, and thus converted into ozone, which is a reactive generator. Through this, as the carbon atoms deposited on the surface of the reformed object are separated by combining with the ozone, the surface of the reformed object is converted from hydrophobic in the low energy state to hydrophilicity in the high energy state, so that the bone fusion ability can be remarkably improved.

Moreover, as the container is made of a quartz material having a lower absorption coefficient than a commonly used glass or projectable synthetic resin material, the UV transmittance can be significantly increased, and the sterilizing power of the UV light can be preserved. Through this, the surface modification ability and the sterilization / cleaning ability can be remarkably improved while the high-energy far-infrared rays irradiated from the ultraviolet lamp unit 720 are substantially irradiated to the surface of the reformed object.

On the other hand, the rotating jig portion 730 is arranged on the lower side of the ultraviolet lamp portion 720 along a transverse direction corresponding to the arrangement direction of the ultraviolet lamp portion 720, including a plurality of rollers 732 provided It is preferably provided. At this time, the plurality of rollers 732 is preferably disposed adjacent to each other such that a rotational seating area J in which the modified object is seated is formed along the longitudinal direction of the upper side of the opposite inner surface. Moreover, each interval in which the plurality of rollers 732 are disposed adjacent to each other may be formed to be narrower than a short width interval of the modified object, that is, a cross-sectional width in the longitudinal direction and the vertical direction.

Hereinafter, an example of a pair of the plurality of rollers 732 will be described and illustrated.

In detail, the ultraviolet lamp unit 720 and the pair of rollers 732 are provided in parallel with each other, and may be disposed in a transverse direction, that is, in a horizontal direction to substantially correspond to the bottom surface portion 771a.

Therefore, the modified object can be easily mounted or detached from the ultraviolet irradiation device 700 by a simple method of placing the modified object along the longitudinal direction of the rotational seating area J, so that the convenience of use can be significantly improved. In addition, the driving stability can be remarkably improved since the state in which the modified object is seated in the rotation seating area J is stably supported in the gravitational direction by its own weight without additional restraining or coupling means.

Moreover, as the pair of rollers 732 are each provided in a cylindrical shape, the opposite inner surface side upper portions are concave, but are provided with a profile convex toward each opposite outer surface side. Through this, even if the object to be modified seated on the rotational seating area (J) is rotated relative to its center, it can be prevented that the rotational position is changed or deviated to the outside of each opposing outer surface. In addition, since the rotation center of the object to be modified is rotated while being maintained at a constant distance from the outer surface of the UV lamp unit 720, the surface modification may be uniform. Here, it is preferable to understand that the object to be modified is rotated substantially in the same sense.

At this time, the pair of rollers 732 extends corresponding to the longitudinal direction of the ultraviolet lamp unit 720, but the ultraviolet lamp unit 720 and the pair of rollers 732 exceed the long width of the modified object. It is preferably formed. For example, the pair of rollers 732 may be extended to a length capable of simultaneously arranging 4 to 5 pieces of the reformed object along the longitudinal direction, and the ultraviolet lamp unit 720 may include a pair of rollers 732. It can be extended to a length that can cover the whole. Through this, a plurality of modified objects can be surface-treated at a time through one UV lamp unit 720, so that utilization and economics can be significantly improved.

On the other hand, the rotation driving unit 740 is provided to provide a rotational force to rotate the pair of rollers 732, and preferably includes a rotating pulley 741, a driving motor 742, and a belt 743.

In detail, the rotary pulley 741 is provided to correspond to the pair of rollers 732, respectively, and is preferably fastened coaxially with the rotational axis of each roller 732 at at least one end of both ends of each roller 732. . In addition, the belt 743 is preferably provided to simultaneously wrap a pair of rotating pulleys 741 corresponding to the pair of rollers 732 and a rotating shaft connected to one side of the drive motor 742.

That is, the rotation drive unit 740 is rotated while the belt 743 is rotated by the rotational force provided when the driving motor 742 is driven, and the angles connected to the respective rotation pulleys 741 and the respective rotation pulleys 741 The rollers 732 are rotated simultaneously. Accordingly, as the modified object, which is seated in the longitudinal direction of the rotational seating area J, rotates while rubbing against the surfaces of the pair of rollers 732, ultraviolet light emitted from the ultraviolet lamp unit 720 is the modified object. The entire surface of can be uniformly irradiated.

Moreover, as the outer surface is formed to have a predetermined friction coefficient, the modified object may be stably rotated in response to the rotational speed and the number of rotations of the plurality of rollers 732. Therefore, since the surface of the object to be modified is uniformly modified as a whole, the bone adhesion ability after implant placement can be remarkably improved. Of course, in some cases, the rotating pulley may be provided in a sprocket shape, and the belt may be provided in a chain shape, and such a modification belongs to the scope of the present invention.

In addition, the object to be modified preferably includes an ampoule portion 750 provided with an ultraviolet projection window 751 so that the dental implant is accommodated therein and ultraviolet rays for surface modification of the dental implant are transmitted. That is, the dental implant may be seated directly on the rotational seating area J, but preferably, contamination due to direct exposure and contact with the external environment is minimized as it is accommodated and seated inside the ampoule portion 750. Hygiene can be improved.

In detail, referring to FIG. 4, the ampoule portion 750 includes a hollow cylindrical projection body portion including the ultraviolet projection window 751, and stopper portions 752a and 752b on both open sides of the projection body portion. Can be combined.

At this time, as the UV projection window 751 is substantially formed on the entire body of the projection body, the UV light can be substantially transmitted along the circumferential direction of the ampoule portion 750. Thus, the ampoule portion 750 is seated on the rotational seating region J, and the ultraviolet rays can be irradiated to the entire surface of the dental implant accommodated therein during rotation, so that the surface modification ability can be remarkably improved.

Here, through passages 756a and 756b may be formed along the longitudinal direction of the stopper portions 752a and 752b so that oxygen molecules are supplied into the projection body portion. In addition, an NFC (near field communication) tag may be attached to the ampoule portion 750 to prevent contamination of the reformed object due to reuse of the ampoule portion 750.

Hereinafter, the modified object is described and illustrated as an example provided with the ampoule portion 750. In this case, the drawing shows an example in which the dental implant accommodated inside the ampoule portion 750 is provided as a fixture (f), but is not limited thereto, and is generally applied to a plant that requires surface modification such as abutment. Can be used.

On the other hand, the ultraviolet irradiation device 700 of the present invention emits ultraviolet rays of high energy but requires a converter for boosting and boosting the voltage provided at 220v according to a typical rated voltage as an excimer lamp requiring high voltage is applied. . In addition, since high temperature heat is generated while converting alternating current to direct current, a structure capable of providing driving stability of the product by cooling the high temperature heat is provided. Here, it is preferable to understand that cooling the heat is to lower the temperature by lowering the internal heat rising to a high temperature through blowing.

In detail, the ultraviolet irradiation device 700 is a first blower for generating an air flow ca1 that is blown across the rotational seating area J between the ultraviolet lamp part 720 and the rotating jig part 730. It is preferred to include (781).

In this case, referring to FIGS. 3 to 5, the first blowing portion 781 extends in a transverse direction corresponding to the arrangement direction of the ultraviolet lamp portion 720 and the rotating jig portion 730 and the housing portion ( 770) is disposed on the front portion (772a) side. The first blower 781 may be provided as a cross flow fan.

In detail, the cross flow fan generates suction and discharge of air in a direction perpendicular to the rotational axis of the impeller, and is formed by spaced apart from the suction and discharge parts. That is, the airflow ca1 is generated by a force in which air sucked through the suction portion of the first blowing portion 781 is discharged to the discharge portion in response to the rotation of the impeller. Such a cross-flow fan is generally advantageous for producing a large amount of air while maintaining a fixed pressure, and because the air stream ca1 is uniformly blown along the axial direction, the ultraviolet lamp unit 720 and the rotating jig unit 730 It can be uniformly cooled as a whole in response to the lateral direction.

At this time, the discharge portion of the first blowing portion 781 may be formed corresponding to the longitudinal direction of the rotational seating area J between the ultraviolet lamp portion 720 and the rotating jig portion 730. Therefore, since the air stream ca1 generated from the first blowing portion 781 is discharged to the rotational seating region J through the discharge portion, the entire area of the rotational seating region J can be simultaneously cooled.

In addition, since the discharge portion of the first blowing portion 781 is opened corresponding to the transverse direction in which the ultraviolet lamp portion 720 and the rotating jig portion 730 are arranged, the discharge portion of the first blowing portion 781 is It is formed to substantially correspond to the overall separation distance of the rotation seating area (J). Therefore, a plurality of modified objects to be seated along the longitudinal direction of the rotation seating area J can be cooled to a substantially uniform temperature.

In addition, it is preferable that the discharge portion of the first blowing portion 781 is provided adjacent to the transverse side of the ultraviolet lamp portion 720 and the rotating jig portion 730. Therefore, since the air flow ca1 quickly reaches the rotational seating area J and blows in the other direction of the housing part 770, the heat generated from the ultraviolet lamp part 720 is cooled to cool the reforming space ( G) can be prevented from heating. In addition, the temperature rise of the air stream ca1 due to heat generated from the UV lamp unit 720 is minimized, and thus cooling efficiency can be significantly improved. At this time, one side of the ultraviolet lamp portion 720 and the rotating jig portion 730 is preferably understood in a direction corresponding to the front portion 772a of the housing portion 770.

Through this, failure and malfunction of the component part and the electric component P for driving the component part are prevented, so driving reliability is significantly improved, and the service life of the product can be extended to improve economic efficiency. In addition, since the surface modification and cooling of the modified object are substantially simultaneously performed, the modified object can be quickly used in the implant placement process without a separate cooling process after being taken out of the ultraviolet irradiation device 700. Moreover, since the problems such as tissue damage or deterioration of bone fusion that may occur when the heated dental implant comes into contact with human tissue such as alveolar bone can be prevented, the implant placement stability can be remarkably improved.

Meanwhile, at least one side of both sides of the housing part 770 crosses the airflow ca1 and generates a second airflow unit 782 that generates a mixed airflow ca2 that moves along the longitudinal direction of the rotational seating area J. ) May be further included. That is, as the air flow ca1 generated from the first air blower 781 and the mixed air flow ca2 generated from the second air blower 782 cross each other, the reforming space G is blown. It can be cooled more quickly. The second blowing portion 782 may be provided as a sirocco fan.

In detail, in the sirocco fan, air is introduced in the direction of the rotational axis of the impeller, and air is discharged in the radially outer direction of the impeller, which is perpendicular to the inflow angle. That is, after the air sucked through the suction portion of the second blowing portion 782 flows into the impeller and is compressed, it is discharged through the discharge portion formed in the radially outward direction of the impeller to generate the mixed air stream ca2.

Such a Shikoro fan has a higher discharge rate and pressure of air compared to the same power compared to a general axial fan, and smoothly extends from one side of the rotational seating area J adjacent to the second blowing portion 782 to the other side extending in the longitudinal direction. Since it is moved, the cooling efficiency can be improved. In addition, the power consumption used for driving the second blower portion 782 is low, and the noise generated during driving is small, so that the working environment can be significantly improved. Of course, in some cases, the first air blower 781 and the second air blower 782 may be further provided with cooling means for cooling the air stream ca1 and the mixed air stream ca2 to a predetermined temperature or less. have.

Here, the mixing air flow (ca2) may be introduced into the ampoule portion (750) through the through passages (756a, 756b) while moving along the longitudinal direction of the rotational seating area (J). Through this, as the oxygen molecules capable of reacting with the ultraviolet rays and generating ozone are continuously supplied into the ampoule portion 750, the carbon atoms on the surface of the reformed object can be smoothly separated, thereby significantly improving the surface modification ability. You can.

On the other hand, the airflow (ca1) to the outside of the housing portion 770 to the bottom surface portion 771a of the housing portion 770 and the rear side portion 772b which is the other side surface portion opposite to the first blowing portion 781 It is preferable that the third blowing portion 783 and the fourth blowing portion 784 to be discharged are provided.

In detail, a first ventilation part h1 and a second ventilation part h2 including a plurality of through holes are formed in the bottom surface part 771a and the rear part 772b of the housing part 770. In addition, the third ventilation unit 783 and the fourth ventilation unit 784 are provided to cover one side of the first ventilation unit h1 and the second ventilation unit h2. The third blower portion 783 and the fourth blower portion 784 may be provided as a conventional axial flow blowing fan in which the inside air of the housing portion 770 is discharged to the outside while the impeller provided therein is rotated. .

It can be quickly discharged to the outside of the housing portion 770 through (784). Accordingly, the present invention rapidly and stably cools the heat generated when the excimer lamp is driven, as the cooling through airflow discharge and the cooling through heat storage discharge act in combination, thereby significantly improving the driving stability of the product.

In addition, the first blower portion 781 and the fourth blower portion 784 are disposed to face each other, but the direction of discharging / emission of air from each blower portion substantially corresponds to each other. Therefore, even though the air stream ca1 is blown across the rotational seating region J to cool the reforming space G and rises above the initial blowing temperature, it is rapidly discharged through the fourth blowing portion 784. The internal temperature of the reforming space G may be kept constant.

In addition, the fifth blowing portion 785 and the auxiliary blowing portion 786 is more preferably coupled to the upper side of the partition partition wall (775).

Therefore, each air stream and heat storage air discharged from the reforming space (G) side is not moved to the electric component P installed on the lower side of the mounting space (K), but is substantially through the fourth blower (784). It can be released outside. Through this, it is possible to prevent a malfunction caused by exposure to the electronic components P and high temperatures.

On the other hand, the third blowing portion 783 may be coupled to one side of the bottom surface portion 771a opposite to the ultraviolet lamp portion 720 in the vertical direction.

In addition, as the ozone filter is provided in multiple stages in correspondence with the direction in which air is released, the filtration effect of ozone is maximized, so that the amount of ozone released into the working space can be further reduced. Moreover, as the ozone filter is also provided in the third blower portion 783 coupled to the bottom surface portion 771a of the housing portion 770, the ozone filter can be substantially prevented from being released into the working space.

Here, the mesh cover for preventing contact (not shown) may be provided to be in close contact with the outer circumferential surface of the container, but may be provided to be spaced apart at a predetermined distance from the outer circumferential surface of the container. Therefore, direct contact with the outer circumferential surface of the container may be further prevented, and safety and economical efficiency may be improved because the container provided with a quartz material can prevent damage or scratching due to an external collision.

At this time, the gap between the mesh cover for preventing contact (not shown) and the container may be set within the range of the rotation margin (w). That is, even if the container is covered by the mesh cover for preventing contact (not shown), since the outer peripheral surface of the container and the outer surface spacing of the object to be modified are spaced in correspondence with the rotation margin interval w, the surface modification ability may be maintained.

In addition, a cooling passage through which the cooling fluid is moved may be formed in the pair of rollers 732 along the longitudinal center portion. Through this, even if the ultraviolet light irradiated from the ultraviolet lamp unit 720 passes through the ampoule portion 750 and is irradiated on the upper surface of the pair of rollers 732, it is possible to prevent the plurality of rollers 732 from being heated to a high temperature. have.

On the other hand, the ultraviolet irradiation device 700 of the present invention may include a structure capable of improving the surface modification ability while improving the ease of use of the product by easily changing the position of the ultraviolet lamp unit 720 by a simple operation.

In detail, the UV lamp unit 720 is connected to the lifting frame 774, and the lifting frame 774 may be provided to be selectively lifted. Accordingly, the ultraviolet lamp unit 720 may be selectively proximate or spaced from the outer surface of the rotating jig unit 730 arranged on its lower side. At this time, the outer surface of the outer side of the rotary jig portion 730 means the outer surface of the pair of rollers 732, more preferably the upper outer surface on which the modified object is seated.

In detail, between the lower outer surface of the ultraviolet lamp unit 720 and the upper outer surface of the pair of rollers 732 in the descending state of the lifting frame 774 is set to be less than a short width interval of the modified object, a preset rotation margin It may be provided so that the interval (w) is set.

Moreover, referring to FIGS. 3 to 4, the ampoule portion 750 is seated along the longitudinal direction of the rotation seating area J. Then, when the lifting frame 774 is lowered, the lower outer surface of the ultraviolet lamp unit 720 may be disposed adjacent to the upper outer peripheral surface of the ampoule portion 750.

In addition, when the pair of rollers 732 are rotated in the same direction by the rotational force transmitted when the rotation driving unit 740 is driven, the ampoule portion 750 rubs against the surface of the pair of rollers 732. It rotates in the other direction.

At this time, the modified object is supported in the direction of gravity by the weight of the ampoule portion 750 and the fixture (f) accommodated therein and rotates within the rotational seating area (J), so the surface is modified in the minimum space. This can be done. That is, the modified space (G) requires only a minimum space in which the ultraviolet lamp unit 720, the pair of rollers 732, and the rotary driving unit 740 can be accommodated, so the ultraviolet irradiation device 700 Can be compact and compact. In addition, the components for surface modification of the reformed object are provided in a simple structure sequentially stacked in the reforming space G, and the shape of each part is not complicated, so assembly / manufacturing work and manufacturing cost can be significantly reduced. .

Meanwhile, the rotation margin (w) may be set in a range of 0.5 to 5 mm.

That is, as the minimum distance of the rotation margin (w) is set to 0.5 mm or more, the outer peripheral surface of the ampoule portion 750 may be disposed close to the lower outer surface of the UV lamp unit 720 at the minimum distance. Therefore, even if the ampoule portion 750 is rotated, it is prevented from contacting and interfering with the ultraviolet lamp portion 72, so that damage caused by this or the ampoule portion 750 is pressed by the ultraviolet lamp portion 750 to rotate. Driving stability can be significantly improved by preventing interference.

In addition, as the maximum distance of the rotation margin (w) is set to 5 mm or less, the distance between the lower outer surface of the UV lamp part 720 and the surface of the ampoule part 750 is set to the minimum distance that can be rotated. Can be. Accordingly, since the energy attenuation rate due to exposure of short-wavelength ultraviolet rays, particularly vacuum ultraviolet rays to the air, is minimized, the entire circumferential surface of the dental implant through high-energy ultraviolet rays can be uniformly modified and sterilized in a short time.

Moreover, in the lowered state of the elevating frame 774, a first interval in which an outer outer surface of the rotating jig portion 730 and a lower outer surface of the ultraviolet lamp portion 720 are separated is an upper outer surface of the ampoule portion 750 The UV lamp unit 720 may be set to an interval that can be spaced apart from the lower outer surface and the rotation margin (w). At this time, the first interval may be formed with a width that exceeds the radius of the ampoule portion 750 but smaller than the outer diameter.

In detail, the rotation seating area J is formed on the opposite inner surface formed with a concave profile while the pair of rollers 732 are disposed adjacent to each other, and the ampoule portion 750 maintains a constant rotational center during rotation. It is provided in a circular shape. Therefore, the ampoule portion 750 may be seated in a shape in which the pair of rollers 732 are partially inserted into a concave profile disposed adjacent to each other. Accordingly, a gap between the upper surface of the ampoule portion 750 seated in the rotation seating area J and the upper outer surface of the plurality of rollers 732 may be formed to have a width smaller than the outer diameter of the ampoule portion 750. .

In addition, the gap between the opposing inner surfaces of the pair of rollers 732 is the outer diameter of the ampoule part 750 so that the ampoule parts 750 are simultaneously contacted and seated on the opposite inner surfaces of the pair of rollers 732. It is formed smaller. Accordingly, a gap between the upper surface of the ampoule portion 750 seated in the rotation seating area J and the upper outer surface of the pair of rollers 732 may be formed to have a width greater than the radius of the ampoule portion 750. .

Through this, the lower outer surface of the ultraviolet lamp unit 720 in the lowered state of the lifting frame 774 may be regularly spaced in correspondence with the upper outer surface of the ampoule unit 750 and the rotation margin (w). . Therefore, since the ampoule portion 750 is stably seated on the upper side of the pair of rollers 732 and rotated at a constant rotational speed, the surface of the dental implant may be uniformly modified as a whole.

In addition, the external surfaces of the UV lamp unit 720 and the ampoule unit 750 may be prevented from being damaged or rotated due to friction or contact, thereby improving driving reliability. In addition, since the interval at which short-wavelength ultraviolet rays reach the surface of the reformed object is minimized, the surface modification ability can be remarkably improved.

At this time, as the UV lamp unit 720 is provided with a coupling portion at the end of the lifting frame 774 to be selectively detachable from the lifting frame 774, the UV lamp unit 720 can be replaced, thereby maintaining maintenance. This may be improved.

Meanwhile, a gap between the outer surface of the ultraviolet lamp unit 720 and the outer surface of the rotating jig unit 730 in the rising state of the lifting frame 774 may be formed larger than the outer diameter of the ampoule unit 750. .

In detail, referring to FIG. 6, when the lifting frame 774 is raised, the UV lamp unit 720 connected thereto is spaced upward from the outer surface of the rotating jig unit 730 in the upward direction of the reforming space G. As it is arranged, free space can be secured.

Therefore, it is easy to operate the ampoule part 750 by using an operator's hand or an attaching means, and it is possible to prevent detachment and damage due to contact with surrounding components while moving the ampoule part 750. In addition, since safety accidents such as burns that may occur due to contact of a human body such as a hand with the ultraviolet lamp unit 720 heated by heat generated when the ultraviolet rays are emitted can be prevented, safety in use can be significantly improved.

Here, as the lifting frame 774 is connected to the inner surface side of the door portion 773, the lifting frame 774 may be interlocked and raised when the door portion 773 is opened or closed.

In detail, referring to FIG. 3 or 6, the door portion 773 is provided with an area that covers the opening 771c, and a lateral side edge is hinged to one side edge of the opening 771c to rotate the hinge. Can be.

Therefore, when the door portion 773 is hinged and opened, the lifting frame 774 connected to the inner surface side of the door portion 773 and the ultraviolet lamp portion 720 connected to the lifting frame 774 are integrally formed. It can be interlocked and raised at the same time. In addition, when the door portion 773 is hinged to cover the opening 771c, the lower outer surface of the ultraviolet lamp portion 720 is disposed on the outer side of the rotating jig portion 730, and the ampoule portion ( 750) may be automatically arranged to be spaced in correspondence with the upper outer surface and the rotation margin (w).

That is, according to the present invention, since the lifting frame 774 is interlocked by a simple method of opening and closing the door portion 773, the arrangement position of the UV lamp portion 720 is easily moved, so that the convenience of operation can be significantly improved. In addition, in the closed state of the door portion 773, the UV lamp unit 720 connected to the lifting frame 774 is positioned at a position corresponding to a minimum rotation margin interval w on the upper side of the rotating jig unit 730.
