Description

Technical Field

[0001] This utility model belongs to the field of optical fiber guide rod technology, and in particular relates to an optical fiber assembly for dental treatment. Background Technology

[0002] A dental fiber optic light guide is a medical tool designed based on fiber optic technology, primarily used for the efficient transmission of specific wavelengths of light energy in dental light-curing treatments. Traditional dental curing light sources (such as halogen lamps or early LED devices) suffer from problems such as high heat generation, uneven light intensity distribution, or insufficient optical path flexibility, which may cause patient discomfort or affect the curing effect of resin materials. The fiber optic light guide, through a flexible or adjustable-angle fiber bundle structure, precisely transmits high-energy blue light (typically 460-480nm) emitted by the light source to the oral treatment area. Its core advantages lie in low heat loss, high light transmission efficiency, and directional control capabilities, thereby reducing thermal damage to surrounding tissues and improving curing uniformity.

[0003] Firstly, the cladding material of traditional dental light guides has a high refractive index, which cannot meet the condition of total internal reflection, resulting in light leakage and low transmission efficiency. Secondly, the intermediate coating is rigid, prone to aging, lacks flexibility and high temperature resistance, and is prone to cracking or oxidation, causing interface scattering and light loss. Thirdly, the outer layer has no lateral light recovery structure, so the light that leaks out of the fiber cannot be reflected back to the fiber core, resulting in energy waste.

[0004] Secondly, most traditional light guide rod connectors use static rubber rings and curing machines for elastic compression connection. If you want to increase the reliability of the connection, you can only increase the protrusion height of the rubber ring, but this is not conducive to the insertion and removal of the connector and the curing machine socket. Insufficient protrusion height will affect the reliability of the connection.

[0005] To address the aforementioned issues, this application proposes an optical fiber assembly for dental treatment. Utility Model Content

[0006] The purpose of this invention is to provide an optical fiber assembly for dental treatment, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is an optical fiber assembly for dental treatment, including a light guide component and a connector fixed on the light guide component and connected to a dental curing machine. The connector includes a plug and a plug seat. The plug is covered with a rubber ring, and the plug is slidably provided with a protrusion that pushes the rubber ring outward and expands. The expansion action is achieved by the thrust at the end of the plug during the insertion of the plug with the curing machine.

[0009] The light guiding component includes an inner optical fiber core and an inner cladding, an intermediate layer, and an outer cladding formed sequentially outside the optical fiber core. It also includes an outer sheath at the outermost part of the light guiding component. The inner cladding is a polytetrafluoroethylene (PTFE) molded component.

[0010] Furthermore, the protrusion is fixed to the outer surface of the arc-shaped plate, and one end of the arc-shaped plate is fixedly installed with the linkage ring. The end of the plug near the plug seat has a movable groove for the axial sliding of the linkage ring.

[0011] Furthermore, the outer ring of the plug is provided with an annular groove that connects to the rubber ring, and the inside of the plug is provided with an arcuate groove along the axial direction for sliding of the arcuate plate and the protrusion, and the arcuate groove is at least partially interconnected with the annular groove.

[0012] Furthermore, as the linkage ring slides from the plug head to the plug seat, it causes the protrusion to press against the inner side of the rubber ring, causing it to expand against the inner wall of the curing machine socket.

[0013] Furthermore, the arc-shaped plate has several evenly distributed blocks in the circumferential direction of the linkage ring.

[0014] Furthermore, several protrusions are provided axially on the outer side of the arc-shaped plate.

[0015] Furthermore, the intermediate layer is a silicone resin molded component, and the outer layer is a metal plating layer.

[0016] Furthermore, the outer side of the plug seat is provided with a clearance opening adapted to the linkage ring.

[0017] This utility model has the following beneficial effects:

[0018] This invention utilizes an inner cladding made of polytetrafluoroethylene (PTFE) outside the fiber core, which has a low refractive index, ensuring total internal reflection and reducing light leakage. It also features low absorption and high chemical stability. The intermediate layer made of silicone resin outside the inner cladding reduces interface scattering during light transmission, provides a low refractive index environment, and further reduces light loss. The outer cladding made of aluminum outside the intermediate layer reflects light, captures laterally leaked light, and reflects it back to the fiber core, reducing light loss and providing high-temperature resistance.

[0019] This utility model, by setting the cooperation between the protrusion and the rubber ring, facilitates the insertion of the connector and the curing machine when the two are not squeezed, and ensures a stable connection between the connector and the curing machine when the two are squeezed. Then, the linkage ring combines the insertion of the connector with the expansion of the rubber ring, making the operation more flexible and convenient.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements 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.

[0032] Please see Figures 1-6 As shown, the present invention is an optical fiber assembly for dental treatment, including a light guide component 1 and a connector 2 fixed on the light guide component 1 and connected to a dental curing machine. The connector 2 includes a plug 21 and a plug seat 22. A rubber ring 3 is sleeved on the outside of the plug 21. A protrusion 41 is slidably provided inside the plug 21 to push the rubber ring 3 outward and expand it. The protrusion 41 has a sloping surface on the side near the rubber ring 3. The squeezing action between the two forms a transition, and the expansion action is achieved by the thrust at the end of the plug 21 during the insertion of the plug 21 into the curing machine. This expansion work is only formed when the linkage ring 42 abuts against the end of the curing machine socket and continues to push the plug 21 into the socket.

[0033] The light guiding component 1 includes an inner optical fiber core 11 and an inner cladding layer 12, an intermediate layer 13 and an outer cladding layer 14 sequentially formed outside the optical fiber core 11. It also includes an outer sheath 15 at the outermost part of the light guiding component 1. The inner cladding layer 12 is a polytetrafluoroethylene molded component.

[0034] The protrusion 41 is fixed on the outer surface of the arc plate 4, and one end of the arc plate 4 is fixedly installed with the linkage ring 42. The end of the plug 21 near the plug seat 22 has a movable groove 213 for the axial sliding of the linkage ring 42.

[0035] The plug 21 has an outer ring groove 211 that connects to the rubber ring 3. The plug 21 has an axial groove 212 for sliding of the arc plate 4 and the protrusion 41. The arc groove 212 is at least partially connected to the ring groove 211. The connected part causes the protrusion 41 to press against the rubber ring 3, thereby forming an outward expansion.

[0036] When the linkage ring 42 slides from the plug head 21 to the plug seat 22, it causes the protrusion 41 to press against the inner side of the rubber ring 3 and expand it against the inner wall of the curing machine socket. This engagement can achieve linkage when the plug head 21 is connected to the curing machine socket, which is both easy to insert and reliable after insertion.

[0037] Among them, the arc plate 4 is provided with several evenly distributed blocks in the circumferential direction of the linkage ring 42. The increase in the number of arc plates 4 increases the number of support points for a single rubber ring 3. The more blocks there are, the better the compression and expansion effect. The actual number needs to be determined according to the actual situation, but there must be at least two arc plates equidistantly distributed in the circumference.

[0038] Among them, several protrusions 41 are provided on the outer side of the arc plate 4 along the axial direction. The number of protrusions 41 is determined according to the number of rubber rings 3, forming a one-to-one extrusion.

[0039] Among them, the intermediate layer 13 is a silicone resin molding component. Silicone resin has the advantages of good flexibility, high temperature resistance and anti-aging. The outer layer 14 is a metal plating layer, which is either gold plating or silver plating. To control costs, silver plating is preferred. It is necessary to ensure the stability of the plating process and avoid biocompatibility issues.

[0040] Among them, the outer side of the plug seat 22 is provided with a clearance opening 221 adapted to the linkage ring 42. The clearance opening 221 is used to abut the linkage ring 42 against the curing machine when the optical fiber assembly is pulled out. During the pulling action, the protrusion 41 is first separated from the rubber ring 3, so as to facilitate the subsequent pulling out.

[0041] Understandably, the inner cladding of the optical fiber uses polytetrafluoroethylene to achieve low refractive index total internal reflection, reducing light leakage and providing high chemical stability; the middle layer uses silicone resin to reduce interface scattering and refractive index to suppress light loss; the outer cladding is aluminum-plated to reflect lateral light leakage and resist high temperatures; at the same time, a linkage mechanism between the bump and the rubber ring is set, and the joint insertion action and the rubber ring expansion are synchronously controlled through the linkage ring to achieve convenient insertion and removal and stable connection.

[0042] One specific application of this embodiment is as follows: Figure 1 and Figure 3 The diagram shows the unconnected state. At this time, the protrusion 41 is offset from the rubber ring 3, and the rubber ring 3 is normally placed in the annular groove 211. When this optical fiber assembly needs to be connected to the curing machine, pinch the plug seat 22 and insert the plug head 21 part into the curing machine socket. The curing machine can be easily connected when it is not in contact with the linkage ring 42 because the friction between the rubber ring 3 and the inner wall of the curing machine socket is not large. Then continue to push the insertion. After the plug seat 22 is pushed, the linkage ring 42 contacts the end of the curing machine socket. At this time, the plug head 21 will continue to move into the curing machine socket. The protrusion 41 squeezes it outward from the inside of the rubber ring 3 to form a connection. The light guide component 1 and the light source in the curing machine socket are also connected.

[0043] When removing the fiber optic assembly, first use the clearance port 221 to hold the linkage ring 42 against the curing machine, then pull the plug seat 22 outward to separate the linkage ring 42 from the rubber ring 3 and release the pressure. Then the fiber optic assembly can be removed.
