Description

Technical Field

[0001] This utility model relates to the field of oral medical device technology, and more specifically, to an assembled oral laser fiber head structure. Background Technology

[0002] In the field of oral healthcare, laser therapy devices are widely used in various treatment scenarios such as cutting, coagulation, and sterilization due to their advantages of precision, efficiency, and minimal invasiveness. Existing dental laser therapy devices typically have fiber optic heads that are fixedly mounted on the handle. While this integrated design ensures structural stability to some extent, it also introduces several inconveniences.

[0003] First, in actual clinical applications, different treatment scenarios have varying requirements for the type and performance of fiber optic tips. For example, cutting operations require high-power focusing fiber optic tips, while coagulation and sterilization may require diffusion-type or specially coated fiber optic tips. However, because the fiber optic tips are fixed to the handle and cannot be easily disassembled or replaced, medical personnel often need to replace the entire handle and fiber optic tip assembly when facing different treatment needs. This not only increases the cost of equipment use but also reduces treatment efficiency.

[0004] Secondly, considering medical safety and hygiene requirements, the instruments used must be thoroughly cleaned and disinfected after each laser treatment. However, given the current integrated design of the fiber optic head and handle, the fiber optic head is difficult to easily disassemble for separate cleaning. This inconvenience increases the complexity of the cleaning and disinfection process, potentially leading to incomplete cleaning, which in turn affects the treatment safety of the next patient and even increases the risk of cross-infection.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes an assembled dental laser fiber head structure to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] An assembled dental laser fiber optic head structure includes a fiber optic head body, with a fiber optic needle fixedly installed at one end of the fiber optic head body. One end of the fiber optic needle passes through the fiber optic head body and is fixedly connected to a transmission plug. Loading / unloading blocks are fixedly connected to both sides of the transmission plug. A support handle is provided on one side of the fiber optic head body. A transmission fiber is fixedly installed inside the support handle. One end of the transmission fiber passes through the support handle and is fixedly connected to a transmission slot. Limiting grooves are formed on both sides of the transmission slot. The loading / unloading blocks cooperate with the limiting grooves. A quick loading / unloading mechanism is provided above the limiting grooves. A cooling and sterilization mechanism is provided between the fiber optic head body and the support handle.

[0009] Furthermore, in order to achieve a quick connection between the fiber optic head body and the support handle, the quick loading and unloading mechanism includes a shrinkage groove on one side of the limiting groove, a telescopic spring fixedly connected to one end of the shrinkage groove, a self-locking block fixedly connected to the end of the telescopic spring, and a self-locking groove on the surface of the loading and unloading block, which cooperates with the self-locking block.

[0010] Furthermore, in order to facilitate the easy disassembly of the fiber optic head body and the support handle, a lifting inclined block is fixedly connected to one side of the self-locking block, and a pressing inclined block is provided on one side of the lifting inclined block. The inclined surfaces of the lifting inclined block and the pressing inclined block cooperate with each other. A transmission rod is fixedly connected to one side of the pressing inclined block, and push grooves are opened on both sides of the support handle. The end of the transmission rod is slidably installed in the push groove.

[0011] Furthermore, in order to facilitate cooling and sterilization of the fiber optic head body during laser treatment, and to facilitate cleaning and sterilization, the cooling and sterilization mechanism includes a delivery tube fixedly installed inside the support handle, a cooling and cleaning chamber inside the fiber optic head body, a connecting pipe at one end of the cooling and cleaning chamber, and the end of the delivery tube cooperating with the connecting pipe.

[0012] Furthermore, in order to prevent the self-locking block from retracting, positioning plates are fixedly connected to both sides of the inside of the support handle, a return spring is fixedly connected to one side of the positioning plate, and a blocking block is fixedly connected to one end of the return spring. The blocking block is slidably installed in the limiting groove.

[0013] Furthermore, in order to achieve the interconnection between the support handle and the laser source, a transmission plug two is fixedly installed at one end of the support handle, and the transmission plug two is fixedly connected to the transmission optical fiber.

[0014] Furthermore, to facilitate the pushing of the transmission rod and the extrusion block, a pushing block is fixedly connected to the end of the transmission rod.

[0015] Furthermore, in order to enable the transmission rod to automatically reset after being pushed, a second reset spring is fixedly connected inside the push groove, and the end of the second reset spring is fixedly connected to the transmission rod.

[0016] Furthermore, in order to achieve laser transmission between the fiber optic head body and the support handle, the transmission plug 1 mates with the transmission slot.

[0017] Furthermore, to increase the friction of the support handle surface during use, the support handle surface is provided with anti-slip texture.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. The quick-release mechanism between the fiber optic head and the support handle allows for a detachable design of the fiber optic head. When the fiber optic head needs to be replaced for different treatment scenarios (such as cutting, coagulation, and sterilization), only the fiber optic head needs to be replaced, unlike existing technologies that require replacing the entire handle and fiber optic head. This significantly reduces equipment procurement and replacement costs. Medical personnel can quickly and conveniently replace the appropriate fiber optic head according to different treatment needs, greatly improving treatment flexibility.

[0020] 2. The modular structure allows the fiber optic head to be disassembled separately for cleaning and disinfection. Because the fiber optic head has a relatively simple structure, it effectively reduces complex gaps and blind spots at the connection point with the handle. Medical personnel can clean the fiber optic head more thoroughly and comprehensively. Furthermore, the cooling and disinfection mechanism allows for rapid cooling by injecting cooling liquid during laser treatment, and facilitates more convenient and comprehensive cleaning and disinfection of the fiber optic head itself.

[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] According to an embodiment of the present invention, an assembled dental laser fiber head structure is provided.

[0033] Example 1:

[0034] like Figures 1-7As shown, according to an embodiment of the present invention, an assembled dental laser fiber optic head structure includes a fiber optic head body 1. A fiber optic needle 2 is fixedly installed at one end of the fiber optic head body 1 for emitting laser light to treat oral diseases. One end of the fiber optic needle 2 passes through the fiber optic head body 1 and is fixedly connected to a transmission plug 3. A set of mounting and dismounting blocks 4 are fixedly connected to both sides of the transmission plug 3. A support handle 5 is provided on one side of the fiber optic head body 1 for supporting the fiber optic head body 1. A transmission fiber 6 is fixedly installed inside the support handle 5. One end of the transmission fiber 6 passes through the support handle 5 and is fixedly connected to a transmission slot 7 for transmission... The plug 3 mates with the transmission slot 7 to transmit laser light to the fiber optic head body 1 via the transmission fiber optic cable 6. A pair of limiting slots 8 are provided on both sides of the transmission slot 7. The loading / unloading block 4 mates with the limiting slots 8. A quick-release mechanism 9 is provided above the limiting slots 8, allowing the loading / unloading block 4 on one side of the fiber optic head body 1 to be installed within the limiting slots 8. The quick-release mechanism 9 enables free loading and unloading between the fiber optic head body 1 and the support handle 5. A cooling and disinfection mechanism 10 is provided between the fiber optic head body 1 and the support handle 5 for convenient rapid cooling and cleaning / disinfection of the laser head body. The quick-release mechanism 9 includes limiting slots... A shrinkage groove 901 is formed on one side of the groove 8. A telescopic spring 902 is fixedly connected to one end of the shrinkage groove 901. A self-locking block 903 is fixedly connected to the end of the telescopic spring 902. A self-locking groove 904 is formed on the surface of the loading / unloading block 4. The self-locking groove 904 cooperates with the self-locking block 903. A lifting inclined block 905 is fixedly connected to one side of the self-locking block 903. A pressing inclined block 906 is provided on one side of the lifting inclined block 905. The inclined surface of the lifting inclined block 905 cooperates with the inclined surface of the pressing inclined block 906. A transmission rod 907 is fixedly connected to one side of the pressing inclined block 906. Push grooves 908 are formed on both sides of the support handle 5. The transmission rod 907... The end of the fiber optic head is slidably installed in the push groove 908. When the loading and unloading block 4 is installed in the limiting groove 8, the self-locking block 903 is just in sync with the self-locking groove 904. Through the elastic force of the telescopic spring 902, the self-locking block 903 can be slidably installed in the self-locking groove 904, thereby achieving a fixed and stable connection between the fiber optic head body 1 and the support handle 5. When the fiber optic head body 1 needs to be disassembled from the support handle 5, the inclined surface of the pressing inclined block 906 is pressed against the lifting inclined block 905 by pushing the transmission rod 907, thereby causing the lifting inclined block 905 to drive the self-locking block 903 to move upward, which facilitates the separation of the fiber optic head body 1 from the support handle 5.

[0035] like Figures 1-7As shown, the cooling and disinfection mechanism 10 includes a delivery pipe 1001 fixedly installed inside the support handle 5. A cooling and cleaning chamber 1002 is opened inside the fiber optic head body 1. Multiple discharge ports are opened on one side of the outer surface of the cooling and cleaning chamber 1002. A connecting pipe 1003 is provided at one end of the cooling and cleaning chamber 1002. The end of the delivery pipe 1001 cooperates with the connecting pipe 1003. Through the mutual connection between the fiber optic head body 1 and the support handle 5, the end of the delivery pipe 1001 is connected to the connecting pipe 1003. When the fiber optic head body 1 requires rapid cooling during laser treatment, coolant can be injected into the delivery pipe 1001 and the cooling and cleaning chamber 1002 to rapidly cool one side of the fiber optic head body 1. When the fiber optic head body 1 needs cleaning and disinfection after disassembly, disinfectant can be injected into the cooling and cleaning chamber 1002, effectively improving the disinfection effect of the fiber optic head body 1. Positioning plates 11 are fixedly connected to both sides inside the support handle 5. A return spring 12 is fixedly connected to one side of the positioning plate 11. One end of spring 12 is fixedly connected to a blocking block 13, which is slidably installed in the limiting groove 8. The spring force of spring 12 pushes the blocking block 13 into the limiting groove 8, thus blocking the self-locking block 903 retracted in the shrinkage groove 901. When the loading / unloading block 4 is slidably installed in the limiting groove 8, one end of the loading / unloading block 4 can push the blocking block 13 away from one side of the shrinkage groove 901. One end of the support handle 5 is fixedly installed with a transmission plug 14, which is fixedly connected to the transmission optical fiber 6. The optical fiber 6 inside the support handle 5 is used to facilitate the connection between the transmission fiber 6 and the laser source; the end of the transmission rod 907 is fixedly connected to the push block 15 for facilitating the pushing of the transmission rod 907; the inside of the push groove 908 is fixedly connected to the return spring 16, the end of the return spring 16 is fixedly connected to the transmission rod 907, so that the transmission rod 907 and the pressing inclined block 906 can automatically reset when no pushing force is received; the surface of the support handle 5 is provided with anti-slip texture 17 to increase the friction of the surface of the support handle 5 during use.

[0036] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0037] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, the loading and unloading block 4 at one end of the fiber optic head body 1 is slidably installed into the limiting groove 8 on one side of the support handle 5, and the transmission plug is connected to the transmission slot 7. When the loading and unloading block 4 is slidably installed in the limiting groove 8, one end of the loading and unloading block 4 can push the blocking block 13 away from the shrink groove 901 side. At this time, the self-locking block 903 just cooperates with the self-locking groove 904. Through the elastic force of the telescopic spring 902, the self-locking block 903 can be slidably installed in the self-locking groove 904, thereby realizing the fixed and stable connection between the fiber optic head body 1 and the support handle 5. When the fiber optic head body 1 needs to be disassembled from the support handle 5, the inclined surface of the pressing inclined block 906 is pressed against the lifting inclined block 905 by pushing the transmission rod 907, thereby causing the lifting inclined block 905 to drive the self-locking block 903 to move upward. At this time, the self-locking block 903 no longer limits the loading and unloading block 4, thereby facilitating the separation of the fiber optic head body 1 from the support handle 5.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
