Description

Technical Field

[0001] This utility model relates to the field of excimer lamp technology, and in particular to a device for performing ultraviolet light functionalization modification treatment on the surface of dental or orthopedic implants. Background Technology

[0002] Excimer lamps (especially xenon excimer lamps with a wavelength of 172 nm) generate vacuum ultraviolet light that can effectively decompose organic pollutants and introduce active groups such as hydroxyl groups onto the implant surface, thereby improving its hydrophilicity and biocompatibility. This process is called surface modification or photofunctionalization. However, excimer lamps ionize oxygen in the air during operation, producing ozone. Existing surface modification devices typically use open or large-volume irradiation chambers, resulting in a large amount of air in the working area and a high ozone production. High concentrations of ozone are not only harmful to human health, requiring complex exhaust and purification systems, but also pose a risk of corrosion to internal components, increasing equipment complexity and operating costs.

[0003] Therefore, there is an urgent need for a device for modifying implant surfaces that can effectively suppress ozone generation, has a compact structure, and is safe and reliable. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for modifying implant surfaces that can significantly reduce ozone production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An implant surface modification device includes an inner liner and excimer lamps. The inner liner has a hollow cavity, and the inner wall of the hollow cavity is provided with a plurality of slots distributed circumferentially and extending longitudinally through both ends of the inner liner. The slots have a C-shaped cross-section, and the slot openings face the hollow cavity and communicate with the hollow cavity. The number of excimer lamps is the same as the number of slots, and each excimer lamp is inserted into one slot. The central space formed by the plurality of excimer lamps is an irradiation working area. The excimer lamp has a cylindrical tube body, and the outer peripheral surface of the cylindrical tube body is in contact with the wall of the slot. The surface area of ​​the cylindrical tube body covered by the slot accounts for 3 / 4 to 4 / 5 of the outer peripheral surface area of ​​the excimer lamp.

[0006] As a preferred embodiment of this utility model, the wall surface of the slot is provided with a reflective structure.

[0007] As a preferred embodiment of this utility model, the outer or inner circumferential surface of the part of the cylindrical tube that fits against the wall of the slot is provided with a reflective structure.

[0008] As a preferred embodiment of this utility model, the implant surface modification device further includes a shell, a top cover, an insulating base, and a bottom cover. The insulating base covers the electrical terminal of the excimer lamp and is sealed and fixed to the electrical terminal of the excimer lamp. The shell is fitted over the inner liner and the insulating base. The top cover is detachably connected to the top of the shell, and the bottom cover is detachably connected to the bottom of the shell. The top surface of the inner liner abuts against the top cover, the bottom surface of the inner liner abuts against the top surface of the insulating base, and the bottom surface of the insulating base abuts against the bottom cover.

[0009] As a preferred embodiment of this utility model, the top cover, the insulating base and the bottom cover are respectively provided with an opening in the center, and the opening is connected to the irradiation working area for the insertion and removal of the implant.

[0010] As a preferred embodiment of this utility model, the outer periphery of the inner liner is provided with multiple longitudinally extending heat dissipation ribs, and a heat dissipation channel is formed between two adjacent heat dissipation ribs. The top cover and the top cover are both provided with heat dissipation holes that communicate with the heat dissipation channel.

[0011] As a preferred embodiment of this utility model, the outer shell and the top cover, the insulating base and the bottom cover, and the inner liner and the top cover are all fixed by screws.

[0012] As a preferred embodiment of this utility model, the power receiving end of the excimer lamp tube passes through the insulating base and the outer shell in sequence via a power cord.

[0013] As a preferred embodiment of this utility model, both the slot and the excimer lamp tube are provided with four slots.

[0014] The implant surface modification device according to the embodiments of this utility model has the following advantages compared with the prior art: (1) Highly effective suppression of ozone generation: The C-shaped slot in the inner liner covers most of the excimer lamp tube, strictly confining the ultraviolet light to a very small central working area, thus minimizing the volume of the working area and significantly reducing the amount of air that can be ionized to generate ozone, thereby controlling the ozone concentration at the source.

[0015] (2) Improved irradiation efficiency and uniformity: The compact working area design and optional reflective structure make the ultraviolet energy more concentrated, the utilization rate higher, and the irradiation more uniform, which helps to shorten the processing time.

[0016] (3) Compact and reliable structure: modular design, accurate positioning of each component, firm assembly, good heat dissipation, ensuring the stability and safety of the equipment in long-term operation.

[0017] (4) Simplified equipment and operation: Due to the extremely low ozone production, the additional ozone treatment system can be simplified or even omitted, reducing equipment complexity and cost, and making operation simpler and safer. Attached Figure Description

Detailed Implementation

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figures 1 to 4As shown, the implant surface modification device of the preferred embodiment of this utility model includes an inner liner 1 and multiple excimer lamps 2. The inner liner 1 is made of aluminum alloy through anodizing, and its center is a cylindrical hollow cavity 11. Multiple slots 12 are machined on the inner wall of the hollow cavity 11, evenly distributed along the circumference and extending longitudinally through both ends of the inner liner 1. The number of slots 12 can be adjusted as needed; in this embodiment, four slots are preferred. The cross-section of each slot 12 is C-shaped, with its opening facing the central axis of the hollow cavity 11, allowing the slot 12 to communicate with the interior of the hollow cavity 11.

[0023] The number of excimer lamps 2 (such as 172nm xenon excimer lamps 2) is the same as the number of slots 12, preferably four, with each excimer lamp 2 inserted into a corresponding slot 12. All excimer lamps 2 are arranged around a central axis, and the central cylindrical space they enclose is the irradiation working area, used to place the implant to be treated.

[0024] The key improvement of this embodiment lies in the structure of the excimer lamp 2 and its fitting relationship with the slot 12. The excimer lamp 2 has a cylindrical tube 21, the outer circumferential surface of which is tightly fitted to the wall of the C-shaped slot 12. Through precise design, the surface area of ​​the cylindrical tube 21 covered by the wall of the slot 12 accounts for 3 / 4 to 4 / 5 of the entire outer circumferential surface area of ​​the lamp tube. This large-scale coverage design effectively limits and guides the ultraviolet radiation emitted by the excimer lamp 2 to the central irradiation working area, while greatly reducing the effective volume of the irradiation working area. Due to the reduced volume of the working area, the total amount of air contained within it is significantly reduced. Under the irradiation of the excimer lamp, the amount of ozone generated from the conversion of oxygen in the air is also greatly reduced, fundamentally solving the problem of ozone accumulation. Experiments have verified that under the same conditions, the ozone concentration decreased from 41.5 ppm to 11.9 ppm.

[0025] As a further improvement to this embodiment, a reflective structure (such as mirror polishing or coating with a reflective film) can be provided on the wall of the slot 12, or a reflective structure can be provided on the outer or inner circumferential surface of the excimer lamp tube 2 that is attached to the wall of the slot 12, so as to reflect the light that may have been absorbed or scattered by the inner liner 1 back to the working area, thereby further improving the utilization efficiency and irradiation uniformity of ultraviolet rays.

[0026] For example, the implant surface modification device further includes a shell 3, a top cover 4, an insulating seat 5, and a bottom cover 6, forming a complete protection and support system. The insulating seat 5 is made of high-temperature resistant insulating material, and it covers and seals the electrical terminals of the excimer lamp tube 2, providing insulation and protection. The shell 3 is fitted over the inner liner 1 and the insulating seat 5. The top cover 4 and the bottom cover 6 are detachably connected to the top and bottom of the shell 3, respectively. The top surface of the inner liner 1 abuts against the top cover 4, the bottom surface abuts against the top surface of the insulating seat 5, and the bottom surface of the insulating seat 5 abuts against the bottom cover 6, forming a stable stacked and fixed structure. The top cover 4, the insulating seat 5, and the bottom cover 6 each have an opening 7 in the center, which together form a channel for implant insertion and removal.

[0027] Furthermore, to ensure stable operation of the device over a long period of time, multiple longitudinally extending heat dissipation ribs 13 are provided on the outer peripheral wall of the inner liner 1, and heat dissipation channels 14 are formed between two adjacent ribs. Heat dissipation holes 8 are provided on the top cover 4 and the bottom cover 6, which communicate with these heat dissipation channels 14, so as to effectively dissipate heat from the lamp tube by natural air convection or auxiliary forced air cooling.

[0028] For example, the components (such as the outer shell 3 and the top cover 4, the insulating base 5 and the bottom cover 6, the inner liner 1 and the top cover 4, etc.) are preferably connected and fixed by screws, which makes the structure stable and easy to assemble and maintain.

[0029] For example, the power terminal 22 of the excimer lamp 2 is led out from the side of the insulating base 5 via the power cord 9, passes through the wire hole on the housing 3, and is connected to an external power source.

[0030] During operation, the implant (such as a dental implant) is vertically placed into the irradiation working area through the opening in the center of the top cover 4. When the power is turned on, the excimer lamp 2 emits 172nm wavelength vacuum ultraviolet light to irradiate and modify the implant surface. Because the volume of the irradiation working area is extremely small due to the structure of the inner liner 1, the amount of air within it is very limited, thus greatly reducing the amount of ozone generated. Simultaneously, the heat generated by the inner liner 1 and the lamp is exchanged with the outside air through heat dissipation ribs 13 and heat dissipation channels 14, via heat dissipation holes 8 on the top cover 4 and bottom cover 6, ensuring stable equipment temperature.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
