Description

Technical Field

[0001] This utility model relates to the field of oral care technology, specifically an integrated dental dual-channel nozzle. Background Technology

[0002] In dental clinical practice, the nozzle is a core auxiliary component that ensures the cleanliness of the surgical area, the clarity of the field of vision, and the safety of operation. Its main functions include rinsing the surgical area with fluids (physiological saline, antibacterial rinsing solution, etc.) to rinse away debris and cool the operating tools, or removing accumulated fluid (saliva, blood, rinsing waste liquid, etc.) in the surgical area through negative pressure suction, so as to reduce operation interference and reduce the risk of cross-infection.

[0003] Currently, most dental nozzles in existing technology adopt a single-channel structure design, meaning that a single nozzle has only a single functional channel (either a rinsing channel or a suction channel). However, in post-implantation cleaning scenarios, medical staff need to first use a "single-channel rinsing nozzle" to rinse away blood clots and debris around the implant. After rinsing, the rinsing nozzle needs to be removed and replaced with a "single-channel suction nozzle" to remove fluid from the surgical area. If a second, more detailed rinse is required (such as cleaning residual debris between teeth), the rinsing nozzle needs to be replaced again. The entire process requires repeated disassembly and reassembly of the nozzle. Furthermore, the connection between existing dental nozzles and dental accessories is mostly a threaded connection. Threaded connections require the use of tools such as wrenches and screwdrivers to disassemble and assemble. In dental clinics, doctors often wear double-layered medical gloves, which can easily cause slippage when operating tools.

[0004] In view of this, the present invention solves the above-mentioned technical problems by proposing an integrated dental dual-channel nozzle. Utility Model Content

[0005] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for an integrated dental dual-channel nozzle. Through the coordinated design of the main channel and the secondary channel on the nozzle body, the main channel is responsible for delivering the fluid or solid particles required for treatment, while the secondary channel connects to the dental gun to provide power support. The two work together to achieve integrated operation of "media delivery and power assistance." Simultaneously, the dental accessory fixed at one end of the cannula complements the accessory connected to the dual channels, eliminating the need for repeated disassembly and replacement of single-channel nozzles with different functions as in existing technologies. This significantly simplifies the treatment process, reduces operational interruptions, improves clinical treatment efficiency, and solves the problems of existing single-channel nozzles. The existing channel nozzles only have a single function and require repeated disassembly and replacement. Secondly, the quick-release structure of this utility model can complete the disassembly, assembly, and fixation of dental accessories without additional tools. Quick fixation is achieved by mechanically engaging the locking block and locking hole through a spring-driven mechanism. During adjustment, only a hexagonal tool is needed to rotate the adjusting block to change the locking tightness. During disassembly, the sleeve can be separated by axially pulling it. The operation is simple and smooth, and it is fully suitable for clinical scenarios where doctors wear double gloves. It avoids the trouble of tool slippage, reduces the operational intensity of medical staff, and improves the problem of existing threaded connections requiring tools and being prone to slippage when doctors wear double gloves.

[0006] This utility model provides the following technical solution: an integrated dental dual-channel nozzle, including a nozzle body and dental accessories;

[0007] The top of the nozzle body is provided with a main channel along its axial direction, and the main channel is a through hole that penetrates the nozzle body.

[0008] The top of the nozzle body is also provided with a secondary channel. The secondary channel is inclined and one end of the secondary channel is connected to the main channel, while the other end extends to the surface of the nozzle body.

[0009] The inner walls of both the main channel and the secondary channel are provided with internal threads a;

[0010] The outer periphery of the nozzle body is provided with a quick-release structure for quick assembly and disassembly of dental accessories;

[0011] The quick-release structure includes a sleeve coaxially fitted around the outer periphery of the nozzle body and detachably connected. At least two mounting holes are opened through the surface of the sleeve. A snap-fit ​​block is slidably connected in each mounting hole. The inner wall of the mounting hole is provided with an internal thread b, and an adjusting block is threadedly connected through the internal thread b. A compression spring abuts between the adjusting block and the snap-fit ​​block. The outer peripheral wall of the nozzle body is provided with a snap-fit ​​hole that matches the snap-fit ​​block. Under the elastic force of the compression spring, the snap-fit ​​block is inserted into the snap-fit ​​hole, thereby achieving the snap-fit ​​fixation between the sleeve and the nozzle body.

[0012] As a preferred technical solution of this utility model, the quick-release structure further includes an internal hexagonal connecting hole opened at the end of the adjusting block away from the compression spring. The internal hexagonal connecting hole is used to drive the adjusting block to rotate radially around the sleeve through a hexagonal tool, so as to adjust the pre-compression of the compression spring and thereby change the clamping force between the locking block and the locking hole.

[0013] As a preferred embodiment of this utility model, the end of the snap-fit ​​block facing the snap-fit ​​hole is a hemispherical structure, and the snap-fit ​​hole is a hemispherical groove adapted to the snap-fit ​​block.

[0014] As a preferred embodiment of this utility model, the mounting holes, snap-fit ​​blocks, adjusting blocks, and snap-fit ​​holes are all arranged in a ring array along the circumference of the nozzle body, and the number of arrays is three to six.

[0015] As a preferred embodiment of this utility model, the inner walls of both the main channel and the secondary channel are polished, and the inner wall surfaces of both the main channel and the secondary channel are coated with a medical antibacterial coating.

[0016] As a preferred technical solution of this utility model, the medical antibacterial coating is a nano-silver coating or a zirconium oxide antibacterial coating, which is used to inhibit the growth of bacteria on the inner wall of the channel and reduce the risk of cross-infection.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model utilizes the coordinated design of a main channel and a secondary channel on the nozzle body. The main channel is responsible for delivering the fluid or solid particles required for diagnosis and treatment, while the secondary channel connects to the dental gun to provide power support. The two work together to achieve integrated operation of "media delivery and power assistance". At the same time, the dental accessory fixed at one end of the sleeve complements the accessory connected to the dual channels. Unlike existing technologies, there is no need to repeatedly disassemble and replace single-channel nozzles with different functions, which greatly simplifies the diagnosis and treatment process, reduces operation interruptions, improves clinical diagnosis and treatment efficiency, and solves the problem that existing single-channel nozzles can only achieve a single function and require repeated disassembly and replacement.

[0019] 2. The quick-release structure of this utility model can complete the disassembly and fixation of dental accessories without additional tools. It achieves quick fixation by mechanically engaging the locking block and locking hole through the compression spring. During adjustment, only a hexagonal tool is needed to rotate the adjusting block to change the locking tightness. During disassembly, the sleeve can be separated by axially pulling it.

[0025] 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.

[0026] Please see Figure 1-4 As shown, the integrated dental dual-channel nozzle includes a nozzle body 1 and a dental accessory 101;

[0027] The top of the nozzle body 1 is provided with a main channel 2 along its axial direction, and the main channel 2 is a through hole that penetrates the nozzle body 1.

[0028] The top of the nozzle body 1 is also provided with a secondary channel 201. The secondary channel 201 is inclined and one end of the secondary channel 201 is connected to the main channel 2, while the other end extends to the surface of the nozzle body 1.

[0029] Both the main channel 2 and the secondary channel 201 have internal threads a202 on their inner walls;

[0030] The nozzle body 1 has a quick-release structure on its outer periphery for quick assembly and disassembly of the dental accessory 101;

[0031] The quick-release structure includes a sleeve 203 coaxially sleeved around the outer periphery of the nozzle body 1 and detachably connected. At least two mounting holes 204 are opened through the surface of the sleeve 203. A snap-fit ​​block 205 is slidably connected in each mounting hole 204. The inner wall of the mounting hole 204 is provided with an internal thread b206, and an adjusting block 207 is threadedly connected through the internal thread b206. A compression spring 208 abuts between the adjusting block 207 and the snap-fit ​​block 205. The outer peripheral wall of the nozzle body 1 is provided with a snap-fit ​​hole 209 that is adapted to the snap-fit ​​block 205. The snap-fit ​​block 205 is inserted into the snap-fit ​​hole 209 under the elastic force of the compression spring 208, thereby realizing the snap-fit ​​fixation of the sleeve 203 and the nozzle body 1.

[0032] The quick-release structure also includes an internal hexagonal connection hole 3 opened at the end of the adjusting block 207 away from the compression spring 208. The internal hexagonal connection hole 3 is used to drive the adjusting block 207 to rotate radially around the sleeve 203 by a hexagonal tool, so as to adjust the pre-compression of the compression spring 208, thereby changing the clamping force between the snap-fit ​​block 205 and the snap-fit ​​hole 209.

[0033] The end of the snap-fit ​​block 205 facing the snap-fit ​​hole 209 is a hemispherical structure, and the snap-fit ​​hole 209 is a hemispherical groove that fits the snap-fit ​​block 205.

[0034] Mounting holes 204, snap-fit ​​blocks 205, adjusting blocks 207, and snap-fit ​​holes 209 are all arranged in a ring array along the circumference of the nozzle body 1, and the number of arrays is three to six.

[0035] The inner walls of both the main channel 2 and the secondary channel 201 are polished, and the inner wall surfaces of both the main channel 2 and the secondary channel 201 are coated with a medical antibacterial coating.

[0036] The medical antibacterial coating is a nano-silver coating or a zirconium oxide antibacterial coating, used to inhibit bacterial growth on the inner wall of the channel and reduce the risk of cross-infection.

[0037] The nozzle body 1 has a through main channel 2 extending axially from the top. The main channel 2 has an internal thread b210, which can be directly connected to a dental accessory 101 with an external thread for conveying rinsing fluid, abrasive media, or other fluids or solid particles required for treatment. The nozzle body 1 also has an inclined secondary channel 201 at the top. The secondary channel 201 has an internal thread a202, which is mainly used to connect a dental gun (such as a dental abrasive gun) to provide power support for the treatment process (such as compressed air required for abrasive blasting and negative pressure required for suction). One end of the secondary channel 201 is connected to the main channel 2, and the other end extends to the surface of the nozzle body 1, so that the power provided by the dental gun can be precisely applied to the medium conveyed by the main channel 2, realizing the coordinated operation of "medium delivery and power assistance". At the same time, one end of the sleeve 203 is fixedly connected to another set of dental accessories 101. This accessory complements the accessory connected to the main channel 2 and the secondary channel 201, further expanding the coverage of the treatment function.

[0038] The quick-release structure is used to quickly fix the sleeve 203 and the dental accessory 101 (curved irrigation tube) on the sleeve, ensuring the precise alignment of the accessory with the dual channels: the sleeve 203 is coaxially sleeved on the outer periphery of the nozzle body 1, and at least two mounting holes 204 are opened through its surface. A snap-fit ​​block 205 is slidably connected radially in each mounting hole 204; the inner wall of the mounting hole 204 is provided with an internal thread b206, and the adjusting block 207 is threadedly connected to the mounting hole 204 through the internal thread b206, and a compression spring 208 abuts between the adjusting block 207 and the snap-fit ​​block 205; under the natural elastic force of the compression spring 208, the snap-fit ​​block 205 moves towards the nozzle body 1 and finally embeds into the snap-fit ​​hole 209 opened in the outer peripheral wall of the nozzle body 1, and the sleeve 203 and the nozzle body 1 are axially fixed through mechanical snap-fit, thereby making the dental accessory 101 fixed at one end of the sleeve 203 and the main channel 2 and the secondary channel 201 function stably and collaboratively;

[0039] When adjusting the tightness of the accessory connection or replacing the accessory, use a hexagonal tool to insert into the internal hexagonal connection hole 3 at the end of the adjusting block 207 away from the compression spring 208, driving the adjusting block 207 to rotate radially around the sleeve 203: when rotating the adjusting block 207 clockwise, the adjusting block 207 moves along the internal thread b206 towards the locking block 205, further compressing the compression spring 208, increasing the engagement pressure between the locking block 205 and the locking hole 209, and improving the connection stability of the accessory; when rotating the adjusting block 207 counterclockwise... At 7 o'clock, the spring force of the compression spring 208 is gradually released, and the locking pressure is reduced. If it is necessary to disassemble the accessory, the sleeve 203 is pulled axially directly. The locking block 205 is pushed by the inner wall of the locking hole 209 to compress the compression spring 208 and disengage from the locking hole 209. The sleeve 203 is separated from the nozzle body 1, and the sleeve 203 and the dental accessory 101 fixed at one end can be quickly removed. At the same time, the main channel 2 can also be conveniently disassembled through the internal thread b210 and the secondary channel 201 through the internal thread a202.

[0040] The end of the snap-fit ​​block 205 facing the snap-fit ​​hole 209 is designed as a hemispherical structure, and the snap-fit ​​hole 209 corresponds to a hemispherical groove. The fit between the two can reduce the frictional resistance during disassembly and assembly and avoid component wear. The mounting hole 204, snap-fit ​​block 205, adjusting block 207 and snap-fit ​​hole 209 are arranged in a ring array around the nozzle body 1 to ensure that the sleeve 203 and the nozzle body 1 are subjected to uniform force and prevent structural deformation caused by local stress concentration. The inner walls of the main channel 2 and the secondary channel 201 are polished to reduce the resistance of media transportation and the probability of impurity residue. The inner wall surface is coated with a medical antibacterial coating (nano silver coating or zirconium oxide antibacterial coating) to inhibit bacterial growth and meet the sterility requirements of dental treatment.

[0041] The dental accessories 101 of this utility model include, but are not limited to, irrigation accessories (such as narrow-diameter irrigation tubes, wide-diameter irrigation tubes, and curved irrigation tubes), saliva suction accessories (such as conventional saliva suction tubes, minimally invasive saliva suction tubes, and saliva suction tubes with filters), saliva suction accessories (such as standard sandblasting tubes, fine sandblasting tubes, and adjustable-speed sandblasting tubes), fine cleaning and treatment accessories (such as periodontal pocket irrigation tubes, root canal irrigation tubes, and drug spraying tubes), and auxiliary care accessories (such as gingival massage irrigation tubes and orthodontic cleaning tubes).

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Additionally, in the accompanying drawings of this utility model, the fill patterns are merely for distinguishing layers and do not constitute any other limitation.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
