Description

Plasma surface treatment device and plasma surface treatment method using the same {PLASMA SURFACE TREATMENT APPARATUS AND METHOD FOR PLASMA SURFACE TREATMENT USING THE SAME}

The present invention relates to a plasma surface treatment device that performs surface treatment of an object using plasma and a plasma surface treatment method using the same.

A plasma surface treatment device modifies the surface of an object through plasma treatment.

One of the surface modifications through plasma treatment is to modify the surface of an object from hydrophobic to hydrophilic. This hydrophilic surface modification is widely used in the medical field for artificial bodies such as implants.

To explain in detail, in the case of implants such as fixtures made of titanium or titanium alloy, the titanium surface has hydrophobicity. Therefore, due to the hydrophobic nature of repelling moisture, there is a problem of slowing down the fusion of bone tissue containing blood and protein after implant placement or causing inflammation due to the body's immune response.

In order to solve the above problems, the surface of the implant, which is the target object, is surface modified to be hydrophilic through a plasma surface treatment device.

Conventionally, in order to modify the surface of an implant as an object, plasma surface treatment was performed after the implant was taken out from the packaging material.

However, as described above, there is a problem in that the surface of an implant taken out of the packaging for surface modification is exposed to the air, where an oxidation layer is generated and contaminants such as hydrocarbon compounds accumulate.

In addition, during the process of surface modification of the implant taken out of the packaging material and storage before the procedure, the surface energy is stabilized and becomes hydrophobic again. Therefore, since the procedure must be performed before the surface of the implant is oxidized, there is a problem that the storage period of the implant is short.

In addition, as in the past, when packaging an implant after surface treatment, there is a problem in that additional costs are incurred and a lot of time is required for this.

A plasma surface treatment method according to an aspect of the present invention includes storing an object in an inner space of a chamber surrounded by a dielectric; Exhausting air from the interior space through a vacuum pump; and generating plasma in the internal space by generating a voltage difference between electrodes adjacent to the chamber.

Additionally, the storing step is a step of storing the object in the internal space while being packaged with packaging material.

In addition, in the exhausting step, when the inside of the chamber is in a low pressure state for plasma treatment, the inside of the packaging material is also in a low pressure state, so that the surface of the object in a state packed with the packaging material is not opened. is plasma treated.

A plasma surface treatment device according to another feature of the present invention includes a first dielectric block provided with a receiving space; a second dielectric block sealing or opening an open end of the first dielectric block; a first electrode embedded in the first dielectric block; and a second electrode embedded in the second dielectric block.

Therefore, the conventional problem of the surface of the implant becoming hydrophobic due to exposure of the implant to air can be solved.

Since the air inside the packaging material can be transmitted through the permeable membrane and the inside of the packaging material can be in a vacuum state, plasma can be easily generated inside the packaging material, allowing effective surface treatment of the artificial substitute.

The permeable membrane prevents foreign substances such as bacteria from entering the packaging material, so the sterile state of the artificial substitute can be maintained.

By providing a groove in the internal space to match the shape of the protrusion of the packaging material, the object is received while fixed, and the shape of the lower electrode is formed similar to the shape of the protrusion of the implant and packaging material, allowing surface treatment to be concentrated on the desired area.

As shown in FIGS. 1 to 10, the plasma surface treatment device 10 of the present invention includes a base 110, a frame 120, a first electrode 230, a second electrode 350, and , it may be configured to include a chamber 200, a vacuum pump 400, and an opening/closing unit 300.

The frame 120 is installed on the upper surface of the base 110. A chamber 200 is installed on the upper part of the frame 120. A case 130 is installed on the frame 120, and the case 130 forms the front, rear, left, and right sides of the plasma surface treatment device 10.

An internal space 210 is formed inside the chamber 200. An object 800 is accommodated in the internal space 210.

The internal space 210 of the chamber 200 is a receiving space in which the object 800 is accommodated. In this way, a receiving space in which the object 800 is accommodated is provided in the chamber 200.

The object 800 is an object on which plasma surface treatment is performed. In the present invention, the object 800 may include an artificial substitute 810 and a packaging material 830 for packaging the artificial substitute 810.

The artificial substitute 810 is a part that is implanted into a living body to replace at least a part of the living body, and may include an artificial joint (artificial hip joint, artificial knee joint), an implant, etc., and is included in the packaging material 830. is packaged by

The artificial substitute 810 may be a dental implant fixture, a dental implant abutment, or a dental implant crown.

The artificial substitute 810 is stored in a packaging material 830 equipped with a permeable membrane 850, which will be described later, and stored in the chamber 200. In this case, the chamber 200 may be divided to accommodate a plurality of packaging materials 830 to provide a plurality of accommodation spaces (or a plurality of internal spaces 210).

The packaging material 830 may be provided with a permeable membrane 850.

The permeable membrane 850 is made of a material with micropores that allow air to pass through without allowing water, bacteria, and foreign substances to pass through, and thus selectively allows only air to pass through.

The permeable membrane 850 can be made of a thermoplastic resin by combining fiber structures that are spun in a high-temperature and high-pressure environment. Accordingly, the permeable membrane 850 may be in a high-density, semi-solid state in which liquid cannot permeate. Additionally, the permeable membrane 850 may be bonded without a binder and have fine pores, and water vapor may permeate into the permeable membrane 850, but water or other liquids may not pass through. Accordingly, the permeable membrane 850 can have high waterproofness and high breathability at the same time.

The permeable membrane 850 may have a continuous structure of long fibers, through which it has its own microbial barrier function. Therefore, foreign substances such as asbestos, mold, fiberglass, and lead cannot pass through.

As above, when the artificial substitute 810 is packaged by the packaging material 830, liquid and foreign substances cannot pass through the artificial substitute 810 due to the permeable membrane 850, but air can pass through. . In other words, the packaging material 830 has high waterproofing, high breathability, and foreign matter blocking functions, allowing substances to selectively pass through.

The packaging material 830 may be formed with a protrusion 831 having a shape corresponding to the external shape of the artificial substitute 810. Artificial substitute 810 is received within protrusion 831 and wrapped by permeable membrane 850.

The protrusion 831 may be made of a synthetic resin material such as PVC, and can prevent impact from being applied to the artificial substitute 810.

The internal space 210 of the chamber 200 is provided with a groove 211 into which the protrusion 831 of the packaging material 830 of the object 800 is inserted.

In order for the protrusion 831 to be easily seated in the groove 211, the area of the groove 211 may be formed to be larger than or equal to the area of the protrusion 831. Additionally, the internal shape of the groove 211 may be configured to correspond to the external shape of the protrusion 831. As above, since the groove 211 is provided in a shape corresponding to the external shape of the protrusion 831, the protrusion 831 of the packaging material 830 is inserted into the groove 211 and the object 800 is inserted into the chamber 200. ) can be seated in the internal space 210 of. Furthermore, when the shape of the groove 211 is substantially the same as the shape of the protrusion 831, when the protrusion 831 is inserted into the groove 211, the object 800 has minimal shaking in the internal space 210. It can be accommodated fixed.

A first electrode 230 is provided at the bottom of the chamber 200. The first electrode 230 is provided at the lower part of the chamber 200 so as to be located at the lower part of the internal space 210.

An opening and closing part 300 is installed at the top of the chamber 200 to open and close the internal space 210. The second electrode 350 is provided in the opening and closing part 300.

Accordingly, the chamber 200 is located between the first electrode 230 and the second electrode 350.

Chamber 200 is made of dielectric material. Here, the dielectric material may include glass, quartz, ceramic (alumina), polymer series (polyimide, polypropylene, etc.). Polymers are relatively vulnerable to insulation breakdown compared to materials such as glass, quartz, and ceramics (alumina), so their dielectric constant is relatively low and the surface of the chamber can be oxidized and damaged due to the generation of plasma. Although there are disadvantages, the polymer series is more preferable in this embodiment in that it is easier to manufacture a specific voluminous chamber shape.

The power supply unit is provided at the bottom of the chamber 200, and more preferably is provided at the bottom of the first electrode 230 and connected to the first electrode 230.

As above, the power supply unit is provided below the first electrode 230, the power supply unit applies electricity to the first electrode 230, and the opening/closing unit 300 is insulated by the cover 370, so that the user can access the internal space ( Even if the opening/closing part 300 is held by mistake to open/close 210), there is no electric shock, ensuring high safety.

The first electrode 230 is provided in the lower part of the chamber 200, the second electrode 350 is provided in the opening and closing part 300, and the chamber is provided between the first electrode 230 and the second electrode 350. Since (200) is composed of a dielectric, when the power supply unit applies electricity to the first electrode 230, plasma is generated in the internal space 210 due to the voltage difference between the first electrode 230 and the second electrode 350. is formed

The first electrode 230 is provided in the form of a surface electrode at the bottom of the groove 211.

Surface treatment of the artificial substitute 810 through plasma must necessarily be performed on at least some areas of the artificial substitute 810.

The shape of the first electrode 230 is formed to correspond to a partial area requiring surface treatment. However, when forming the first electrode 230 to correspond to a partial area requiring surface treatment, if the shape of the artificial substitute 810 to be surface treated changes, the shape of the first electrode 230 must also change. Therefore, there is a problem of poor compatibility. Therefore, the shape of the protrusion 831 of the packaging material 830 is manufactured into a shape that can correspond to various shapes of the artificial substitute 810, and the shape of the groove 211 is also formed to correspond to the shape of the protrusion 831. In this configuration, the shape of the first electrode 230 is preferably formed to correspond to the shape of the bottom surface of the groove 211. Through this, surface treatment of the artificial substitute 819 is possible even if the shape of the artificial substitute 810 is varied or the part requiring surface treatment is not specified as a single part.

It is preferable that the horizontal area of the bottom of the protrusion 831 is substantially larger than the horizontal area of the artificial substitute 810 so that the artificial substitute 810 of various shapes can be easily packaged by the packaging material 830, and the protrusion 831 ) is preferably inserted into the groove 211, the horizontal area of the bottom of the groove 211 is preferably substantially larger than the horizontal area of the bottom of the protrusion 831, and the horizontal area of the first electrode 230 is greater than the horizontal area of the protrusion 831. It is preferable that it is substantially larger than the horizontal area of the bottom of the groove 831 and is substantially equal to or smaller than the horizontal area of the bottom of the groove 211.

The horizontal area of the bottom of the groove 211, the horizontal area of the first electrode 230, the horizontal area of the bottom of the protrusion 831, and the horizontal area of the artificial substitute 810 are 'the horizontal area of the bottom of the groove 211. It is desirable to satisfy the following relationship: ≥ horizontal area of the first electrode 230 > horizontal area of the bottom of the protrusion 831 > horizontal area of the artificial substitute 810.

It is preferable that the chamber 200 has an area where the groove 211 is replaceable. As plasma surface treatment is repeatedly performed, the surface of the chamber 200 made of a dielectric material may be oxidized and damaged. Accordingly, a configuration in which at least part of the chamber 200 is detachably coupled can be adopted so that maintenance can be easily achieved by replacing the oxidized and damaged part.

Unlike the shape of the chamber 200 described above, the plasma surface treatment device 10 of the present invention is provided with a chamber 200' having a groove 211' of a different shape, as shown in FIG. 11. can do.

In this case, the groove 211' of the chamber 200' is capable of accommodating a plurality of packaging materials 830 at once and does not correspond to the protruding shape of any one packaging material to ensure high compatibility with packaging materials 830 of various shapes. Alternatively, the bottom of the groove 211' may have a large horizontal area. Additionally, since the shape of the groove 211' is simple, the cost when replacing the chamber 200' can be reduced.

It is preferable that the first electrode 230 is embedded in the bottom surface of the internal space 210 so that the first electrode 230 is not exposed to the bottom surface of the internal space 210.

The first electrode cover 290 is provided to surround the first electrode 230. The first electrode cover 290 is installed at the lower part of the chamber 200 of the first electrode 230 to cover the surface of the first electrode 230 except for the top surface. By covering the first electrode 230 with the first electrode cover 290, electrical leakage is prevented during plasma formation, ensuring high safety.

The first electrode cover 290 may be separately coupled to the chamber 200, and the first electrode 230 may be integrally manufactured by being embedded within the dielectric through insert injection molding.

The opening/closing unit 300 closes or opens the chamber 200. The opening/closing unit 300 is rotatably installed on the upper left side of the frame 120 to open and close the internal space 210 of the chamber 200.

As shown in FIG. 8, the opening and closing unit 300 includes a rotating unit 330 installed on the frame 120 connected to the base 110, and a door member 310 that is rotatably installed by the rotating unit 330. ) and a second electrode 350 installed at the lower part of the door member 310, and surrounding the door member 310 and the second electrode 350, excluding the lower surface of the second electrode 350. It may be configured to include a cover 370 surrounding the .

The door member 310 is installed on the frame 120 by the rotating part 330. The door member 310 can rotate through the heel portion 330, and through this, the opening and closing portion 300 can open and close the internal space 210.

The second electrode 350 is installed on the lower part of the door member 310.

The base 110, frame 120, door member 310, and rotating portion 330 are made of metal and are arranged in a structure that can be electrically connected to each other. Accordingly, the first electrode 230 is grounded through the door member 310, the rotating part 330, the base 110, and the frame 120.

The cover 370 is made of an insulating material (or non-metallic material).

Since the cover 370 made of insulating material entirely surrounds the door member 310 and the second electrode 350, when the user holds the opening/closing part 300 to open or close the internal space 210, the user may receive an electric shock. You can prevent it from happening.

When covering the door member 310 and the second electrode 350, the cover 370 covers the surface excluding the lower surface of the second electrode 350, and the lower surface of the second electrode 350 may be exposed. In contrast, the lower surface of the second electrode 350 may be wrapped with a dielectric material so that it is not exposed to the outside of the second electrode 350.

As described above, the opening and closing unit 300 may include a door member 310 that opens and closes in a rotating manner. Alternatively, it may include a door member that opens and closes in a sliding manner. However, considering the sealing effect described below, the rotation method may be more preferable in this embodiment.

As shown in FIG. 5, a sealing member 250 may be provided on the upper part of the chamber 200 to seal the chamber 200 and the opening and closing portion 300.

A protrusion 251 protruding upward is formed on the upper surface of the sealing member 250. Through these protrusions 251, the lower surface of the opening and closing part 300 and the upper surface of the sealing member 250 come into line contact with each other. As the sealing member 250 comes into line contact with the opening and closing unit 300 through the protrusion 251, the weight of the door member 310, the second electrode 350 and the cover 370 of the opening and closing unit 300 expands the internal space. (210) can be easily sealed. In this way, when the internal space 210 is completely sealed by the sealing member 250, the internal space 210 can be brought into a vacuum state more quickly through the vacuum pump 400. Here, the vacuum state means that the air in the internal space 210 is exhausted to the outside and becomes a low pressure state, and does not need to be a high vacuum state.

The above-described chamber 200 may be a first dielectric block provided with a receiving space.

The opening/closing unit 300 may be a second dielectric block that seals or opens the open end of the first dielectric block.

A second dielectric block is disposed on top of the first dielectric block, and the object 800 can be accommodated in the accommodation space of the first dielectric block, that is, the internal space 210 of the first dielectric block.

The first electrode 230 may be a lower electrode embedded in the first dielectric block, and the second electrode 350 may be an upper electrode embedded in the second dielectric block.

Like the sealing member 250 described above, a sealing member 250 may be provided between the first dielectric block and the second dielectric block to mutually seal the first dielectric block and the second dielectric block.

The plasma surface treatment device 10 of the present invention includes a chamber 200 in which an object 800 is accommodated in an internal space 210, a chamber 200 made of a dielectric, and a lower electrode provided inside the bottom of the internal space 210. and an opening/closing unit 300 installed in the chamber 200 to open and close the internal space 210 at the top of the chamber 200 and having an upper electrode therein, and applying electricity to or grounding the lower electrode to open and close the internal space 210. Plasma is formed in the space 210 to perform surface treatment on the object 800. In this case, the upper electrode is the above-described first electrode 230, and the lower electrode is the above-described second electrode 350.

The first electrode 230 and the second electrode 350, that is, the lower electrode and the upper electrode, are provided opposite to each other with respect to the accommodation space outside the dielectric material accommodation space.

The first electrode 230 is disposed so that a dielectric is provided between it and the object 800.

The second electrode 350 is installed to face the first electrode and is arranged to have a dielectric between it and the object 800.

The chamber 200 made of a dielectric material is provided with a door member 310 to allow entry and exit of the object 800, and the door member 310 is provided with a second electrode 350.

The vacuum pump 400 communicates with the internal space 210 of the chamber 200 and functions to exhaust air from the internal space 210.

Plasma surface treatment is performed on the object 800 accommodated in the internal space 210 while the internal space 210 is in a vacuum state by exhausting the air in the internal space 210 using the vacuum pump 400.

The plasma surface treatment device 10 is provided with an internal space 210 in which the object 800 is accommodated, and upper and lower electrodes are provided on the upper, lower, and upper sides of the chamber 200, respectively, surrounding the internal space 210 with a dielectric. is placed, the air in the internal space 210 is exhausted through the vacuum pump 400 to make the internal space 210 into a vacuum state, and then plasma is generated in the internal space using the voltage difference between the upper and lower electrodes. Surface treatment of the object is performed.

Two electrodes (i.e., first and second electrodes 230 and 350 or upper and lower electrodes) are respectively disposed outside the internal space 210 (i.e., receiving space) of the chamber 200 to form the internal space 210 ( That is, an electric field is generated inside the receiving space. The electric field generated in this way forms plasma and processes the object 800 with plasma.

Accordingly, the artificial substitute 810 inserted into the human body is packaged with packaging material 830 and accommodated in the internal space 210 (i.e., receiving space) of the chamber 200 to contain at least the artificial substitute 810. Some surfaces are treated with sterilizing plasma.

The surface of the artificial substitute 810 sterilized and surface treated by plasma is modified to become hydrophilic. Therefore, when the artificial substitute 810 is implanted, bone tissue is easily fused, thereby preventing inflammation from occurring.

When the internal space 210 is evacuated through the vacuum pump 400, the internal space 210 becomes a low pressure or vacuum state. Additionally, the air inside the packaging material 830 may be transmitted through the permeable membrane 850 so that the inside of the packaging material 830 may be in a vacuum state. Therefore, plasma is easily generated inside the packaging material 830, so that the surface treatment of the artificial substitute 810 can be effectively performed.

The plasma surface treatment device 10 is installed in the chamber 200 so that the inner wall of the chamber 200 and the permeable membrane 850 of the packaging material 830 accommodated in the internal space (i.e., receiving space) of the chamber 200 are spaced apart from each other. It may further include an exhaust space 270 formed therein, and an exhaust hole 231 formed in the chamber 200 to communicate with the exhaust space 270.

The exhaust space 270 is located on top of the permeable membrane 850 of the packaging material 830.

The exhaust hole 231 communicates with the vacuum pump 400.

Even if the object 800 is accommodated in the internal space 210, the exhaust hole 231 is exposed without being blocked by the packaging material 830 or the permeable membrane 850. In other words, the exhaust hole 231 is not blocked by the object 800 (i.e., the packaging material 830 or the permeable membrane 850, etc.) even if the object 800 is accommodated in the internal space 210, and the exhaust hole 231 is an exhaust space. Maintain communication with (270).

When the vacuum pump 400 is operated, the air inside the packaging material 830 flows and is exhausted through the permeable membrane 850, the internal space 210, the exhaust space 270, and the exhaust hole 231 in the order of the packaging material 830. ) The interior and the interior of the chamber 200 are in a vacuum state.

In addition, by forming the exhaust space 270, the air inside the chamber 200 and the packaging material 830 can be easily exhausted. Accordingly, the inside of the packaging material 830 and the inside of the chamber 200 can be more easily brought to a vacuum state.

As above, since the object 800 is received in the internal space 210 inside the chamber 200, that is, in the receiving space, while being packed in the packaging material 830, the inside of the chamber 200 is in a low pressure state for plasma processing. When this happens, the inside of the packaging material 830 is also in a low pressure state, so the surface of the artificial substitute 810 can be plasma treated while it is packed with the packaging material 830, without opening the packaging material 830.

Hereinafter, with reference to FIG. 12, the plasma surface treatment method of the present invention will be described.

Figure 12 is a schematic diagram of the plasma surface treatment method of the present invention.

As shown in Figure 12, the plasma surface treatment method of the present invention,

A step (S10) of storing the object 800 packaged with the packaging material 830 in the internal space 210 of the chamber 200 surrounded by a dielectric, through the vacuum pump 400, A step of exhausting the air in the internal space 210 (S20) and generating a voltage difference between the electrodes 230 and 350 adjacent to the chamber 200 to generate plasma in the internal space 210 of the chamber 200. It may be configured to include step (S30).

In this case, in the storing step (S10), the object 800 is stored in the internal space 210 while being packaged with packaging material 830. Therefore, in the exhausting step (S20), when the inside of the chamber 200 is in a low pressure state for plasma treatment, the inside of the packaging material 830 is also in a low pressure state, so that the packaging material 830 is removed without opening the packaging material 830. The surface of the object 800 is plasma treated while it is packaged.

As described above, the plasma surface treatment device 10 of the present invention and the plasma surface treatment method using the same include an artificial substitute 810 as a packaging material 830 in the internal space 210 of the chamber 200 made of a dielectric. It is received in a packaged state, and through plasma treatment in a vacuum, a portion of the surface of the artificial substitute 810 is surface modified to be hydrophilic, and at the same time, the artificial substitute 810 is sterilized.

Therefore, the artificial substitute 810 packed in the packaging material 830 can be surface treated immediately in the operating room before the artificial substitute 810 procedure, thereby eliminating the conventional problem of inflammation occurring during implantation as it becomes hydrophobic over time. It can be solved.

Additionally, since the internal space 210 is surrounded by the chamber 200 made of a dielectric, there is no need for a separate dielectric.

In addition, it is easy to secure space inside the chamber 200, so that the artificial substitute 810 packed with the packaging material 830 can be easily accommodated, and through this, some surfaces of the packed artificial substitute 810 Plasma treatment can be performed on .

Meanwhile, the plasma surface treatment device 10 further includes a sensor (not shown) that detects the opening and closing of the opening and closing unit 300, and a control unit (not shown) that blocks plasma generation when the opening and closing unit 300 is opened during plasma surface treatment. It can be configured to include.

The control unit is connected to the power unit and sensors. Therefore, when the power supply applies electricity to the first electrode 230, plasma is generated in the internal space 210 of the chamber 200 to perform surface treatment, and the openness of the opening and closing unit 300 is measured through the sensor. When this happens, the control unit (not shown) turns off the power supply. In this way, through the control unit and sensor, it is possible to prevent a safety accident from occurring due to unintentional opening of the opening/closing unit 300 during plasma surface treatment.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely illustrative, and those skilled in the art will understand that various modifications and other equivalent embodiments are possible therefrom. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the attached registration claims.
