Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a UV-curable light guide rod for dental alveoli. Background Technology

[0002] A UV-curing light guide wand for alveolar sockets is a dental medical device used to deliver UV light to the alveolar socket to cure photosensitive resin materials. These wands are typically made of highly transparent materials, such as glass fiber or special polymers, to ensure efficient light transmission. Their design features include a curved tip to better adapt to the complex structure of the oral cavity, especially in the treatment of posterior teeth. This design ensures the wand can be positioned close to the posterior teeth for vertical irradiation, minimizing energy loss.

[0003] A typical UV-curing light guide for dental alveoli consists of a light guide, a curing unit, and a connector. During use, the light guide is securely connected to the curing unit via the connector to ensure efficient light transmission. The curing unit emits UV light of a specific wavelength, which enters the light guide through the connector. The light guide, with its highly transparent material, precisely transmits the light to the dental alveoli, curing the photosensitive resin material.

[0004] However, in some existing devices, the light guide rod needs to be frequently inserted into the patient's mouth, and its bend inevitably comes into contact with the patient's oral cavity wall. Due to the lack of effective protective measures, the friction between the bend of the light guide rod and the oral cavity wall not only damages the patient's oral mucosa, causing pain and discomfort, but also causes wear on the light guide rod itself, affecting its service life and optical performance, and thus affecting the treatment effect and safety. To address these issues, a UV-cured light guide rod specifically designed for alveolar sockets is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a UV-curable light guide rod specifically for alveolar sockets, aiming to improve the problem that some existing devices cannot provide protection against bending of the light guide rod, resulting in friction with the patient's oral cavity.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A UV-curable light guide rod for dental alveoli includes a tube body, a protective mechanism at the top of the tube body, a light-shielding mechanism on the outside of the tube body, and a connecting post fixedly connected to the bottom of the tube body;

[0008] The protective mechanism includes two retaining rings, the outer sides of the two retaining rings are disposed on the outside of the tube body, and protective pads are fixedly connected to adjacent sides of the outer sides of the two retaining rings. Two fixing blocks are fixedly connected to the outer sides of the retaining rings. A slider is fixedly connected to one side of the outer side of one fixing block, and a slot is opened on the outer side of the other fixing block, which is close to the slider. A light-reflecting component is fixedly connected to the inner wall of the tube body.

[0009] As a further description of the above technical solution:

[0010] The refractive component includes a fixing layer, one outer side of which is fixedly connected to the inner wall of the tube, and the other outer side of which is fixedly connected to a connecting layer. The outer side of the connecting layer, i.e. the side away from the fixing layer, is fixedly connected to the refractive layer.

[0011] As a further description of the above technical solution:

[0012] The light-shielding mechanism includes a connecting pad, the inner wall of which is fitted over the outside of the tube body, and support rings are fixedly connected to the top and bottom of the connecting pad.

[0013] As a further description of the above technical solution:

[0014] A light-shielding plate is slidably connected to the outside of the connecting pad, and the outside of the light-shielding plate is located between the outside of the two support rings;

[0015] As a further description of the above technical solution:

[0016] Two rotating columns are rotatably connected to the outer side of the two support rings, and a retaining plate is fixedly connected to the outer side of the two rotating columns;

[0017] As a further description of the above technical solution:

[0018] The two rotating columns are externally rotatably connected to the outside of another rotating column outside the support ring, such that the other side of the clamping plate engages with the outside of the rotating column;

[0019] As a further description of the above technical solution:

[0020] The retaining ring is designed with a relatively soft metal material, which allows the slider to slide into the inside of the retaining groove when bent.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the protective pad is located at the bend of the tube body, which plays a protective role and prevents the bend of the tube body from rubbing against the inner wall of the patient's mouth, avoiding damage and wear, thus improving the comfort and safety of the patient's mouth, avoiding damage caused by friction between the bend of the tube body and the inner wall of the mouth, and improving the patient's medical experience.

[0023] 2. In this utility model, the synergistic effect of the support ring and the rotating column eliminates the instability of the traditional method of fixing by friction of the connecting pad, ensuring that the light shield will not loosen during use, effectively protecting the doctor's vision, ensuring the visual safety of patients and doctors, and improving the efficiency and comfort of clinical operations.

Detailed Implementation

[0031] 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 protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 An embodiment of this utility model is provided: a UV curing light guide rod for dental alveoli, including a tube body 1, a protective mechanism 2 is provided at the top of the tube body 1, a light shielding mechanism 3 is provided on the outside of the tube body 1, and a connecting post 4 is fixedly connected to the bottom of the tube body 1. Its design enables it to be connected to a UV curing machine.

[0033] The protective mechanism 2 includes two retaining rings 21, designed to provide limiting capabilities. The retaining rings 21 are made of a relatively flexible metal material, allowing the slider 24 to slide into the slot 25. The two retaining rings 21 are located on the outside of the tube body 1. By bending the retaining rings 21, they can be removed from the outside of the tube body 1. Protective pads 22 are fixedly connected to adjacent sides of the outer surfaces of the two retaining rings 21, providing good protection. These pads are located at the bend of the tube body 1, preventing friction between the bend and the patient's oral cavity wall during use, thus avoiding injury to the oral cavity and wear on the tube body 1. Two fixing blocks 23 are fixedly connected to the outer surfaces of the retaining rings 21, providing fixation capabilities. These blocks are located at one end of the retaining rings 21 and are close to each other. A slider 2 is fixedly connected to the outer surface of one of the fixing blocks 23. 4. Its design provides engagement capability. Another fixing block 23 has a slot 25 on the outside, near the slider 24. This design provides engagement space, allowing the slider 24 to slide into the slot 25, thus stably fixing the retaining ring 21 to the outside of the tube body 1. A light-refracting component 26 is fixedly connected to the inner wall of the tube body 1. The light-refracting component 26 includes a fixing layer 263, which is designed to provide good adhesion performance. One side of the fixing layer 263 is fixedly connected to the inner wall of the tube body 1, and the other side of the fixing layer 263 is fixedly connected to a connecting layer 262, which provides good connection capability, allowing for a stable connection with the fixing layer 263. The outside of the connecting layer 262, away from the fixing layer 263, is fixedly connected to a light-refracting layer 261, whose main function is to change the direction of light propagation, so that the light can irradiate the alveolar socket area according to a predetermined path and angle.

[0034] Reference Figure 1 and Figure 2The light-shielding mechanism 3 includes a connecting pad 31, designed to provide both connection and sealing capabilities, allowing the connecting pad 31 to slide on the outside of the tube body 1. The inner wall of the connecting pad 31 is fitted over the outside of the tube body 1. Support rings 32 are fixedly connected to the top and bottom of the connecting pad 31, providing good connection and support capabilities. A light-shielding plate 33 is slidably connected to the outside of the connecting pad 31, designed to prevent direct contact between light and the doctor's eyes during use. The outside of the light-shielding plate 33 is located between the outside of the two support rings 32. Two rotating columns 34 are rotatably connected to one side of the outside of the two support rings 32, providing good rotation capabilities. The two rotating pillars 34 are externally fixedly connected to a clamping plate 35, which is designed to provide a locking capability. This allows one side of the clamping plate 35 to be locked onto the outside of another support ring 32, so that the two support rings 32 can be brought closer together by the soft material of the connecting pad 31, thus fixing the light-shielding plate 33. Traditionally, fixing by the friction provided by the connecting pad 31 would be unstable. This allows the light-shielding plate 33 to be clamped by the support ring 32. The two rotating pillars 34 are externally rotatably connected to the outside of the rotating pillar 34 outside the other support ring 32, so that the other side of the clamping plate 35 is locked onto the outside of the rotating pillar 34.

[0035] Working Principle: When using tube 1, first connect the connecting post 4 of the light guide to the light curing machine, ensuring a secure connection so that the UV light emitted by the light curing machine can be smoothly transmitted into the tube 1. Next, check that the protective mechanism 2 is in normal working order, confirming that the retaining ring 21 is correctly fixed to the outside of tube 1 and that the protective pad 22 is located at the bend of tube 1, providing protection and preventing friction between the bend of tube 1 and the patient's oral cavity wall, thus avoiding injury and abrasion. When light curing is required on the alveolar socket, insert tube 1 of the light guide into the patient's oral cavity, aligning it with the alveolar socket area to be cured. At this time, the light refraction component 26 on the inner wall of tube 1 begins to function. After the UV light is transmitted from the light curing machine to the inside of tube 1 through the connecting post 4, it first passes through the fixing layer 263. The fixing layer 263, with its excellent adhesion properties, firmly adheres to the inner wall of tube 1, providing stable support for subsequent light transmission. Subsequently, the light enters the connecting layer 262, which possesses excellent connectivity and can stably connect with the fixing layer 263, ensuring smooth light transmission to the refractive layer 261. The refractive layer 261 receives the light transmitted from the connecting layer 262 and changes the direction of light propagation. Through precise optical design, the refractive layer 261 directs the light along a predetermined path and angle to the alveolar socket, ensuring that the UV light accurately acts on the material to be cured, achieving a highly efficient light curing effect and guaranteeing the normal use and operational safety of the light guide.

[0036] In use, firstly, the connecting pad 31 is fitted onto the outside of the tube body 1, with its inner wall tightly fitting the tube body 1. The position of the light-shielding mechanism 3 is adjusted by sliding the connecting pad 31 to place it in a suitable working area. The connecting pad 31 is made of a soft material, possessing excellent connection and sealing capabilities, ensuring that the light-shielding mechanism 3 is stably fixed to the tube body 1 while preventing external contaminants from entering. The light-shielding plate 33 is slidably connected to the outside of the connecting pad 31, located between the two support rings 32. During use, the light-shielding plate 33 effectively blocks light, preventing UV light from directly irradiating the doctor's eyes and protecting the doctor's vision. When it is necessary to fix the light-shielding plate 33, the clamping plates 35 on the two rotating columns 34 are rotated, causing one side of the clamping plate 35 to engage with the outside of the other support ring 32. This design utilizes the supporting capacity of the support rings 32 and the rotational capacity of the rotating columns 34, allowing the two support rings 32 to approach each other, thereby clamping the light-shielding plate 33 and achieving stable fixation. Traditional fixing methods rely solely on the friction provided by the connecting pad 31, which can lead to unstable fixation of the light-shielding plate 33. This design uses a support ring 32 to clamp the light-shielding plate 33, providing a more reliable fixing method. Simultaneously, the external rotatable connection of the rotating column 34 to another rotating column 34 outside the support ring 32 allows the other side of the clamping plate 35 to engage with the outside of the rotating column 34, further enhancing the stability and reliability of the light-shielding mechanism 3. Throughout the operation, the various components of the light-shielding mechanism 3 work together to ensure that the light-shielding plate 33 is stably fixed in the required position, effectively blocking light and protecting the visual safety of doctors and patients. This design not only improves operational convenience but also enhances the safety and reliability of the light guide in clinical use.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
