Description

Technical Field

[0001] This utility model relates to the field of dental instrument technology, specifically to a three-way cleaning gun barrel for dental cleaning. Background Technology

[0002] In dental treatments, the three-way nozzle plays a crucial role as a key cleaning tool. It has the function of spraying water and / or air into the patient's mouth to meet the needs of different treatment stages.

[0003] In existing three-way pistols, the barrel is bent to a specific angle at the factory and does not spring back. This fixed-angle barrel design has many drawbacks, as follows:

[0004] Because it is difficult to achieve more rinsing angles, it has significant limitations when dealing with complex oral structures, resulting in some areas of the oral cavity not being adequately rinsed.

[0005] When dealing with different patients' oral conditions or different parts of the same patient's oral cavity, the inability to flexibly adjust the rinsing angle affects the rinsing effect and makes it impossible to flexibly adapt to different usage needs.

[0006] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0007] The purpose of this invention is to provide a three-way cleaning gun barrel for dental cleaning.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A three-way dental cleaning gun barrel includes a water tube, a support tube, and an air tube arranged sequentially from the inside to the outside.

[0010] The water pipe has a water delivery channel;

[0011] An air channel is provided between the outer wall of the support tube and the inner wall of the air tube;

[0012] The water pipe has a first connecting section, a first bending section and a second connecting section connected in sequence;

[0013] The support tube has a third connecting section, a second bending section and a fourth connecting section connected in sequence;

[0014] The air pipe has a fifth connecting section, a third bend section and a sixth connecting section connected in sequence;

[0015] The first bending segment, the second bending segment, and the third bending segment are respectively set and can all be bent.

[0016] The first, third, and fifth connecting segments are set accordingly.

[0017] The second, fourth, and sixth connecting segments are configured accordingly.

[0018] It should be noted that the water pipe and air pipe are standard structures of a three-way gun barrel, and the water delivery channel and air channel are also standard designs of a three-way gun barrel. This application has not made any changes to the working principle of the three-way gun barrel.

[0019] The sleeve is a standard setting, and the support is also a standard setting. When installing the sleeve, the support tube can be supported as before, such as by setting a rubber ring between the support tube and the air tube that does not affect the airflow, or by having a raised structure on the surface of the support tube.

[0020] The first, second, and third bends are set up correspondingly. The second and third bends are set up to facilitate bending the first bend.

[0021] In the above scheme, the first, second, and third bends can all be bent. Taking a water pipe as an example, it is illustrated as follows: When in use, by bending the first bend, an angle is formed between the first and second connecting sections, making it easier for the second connecting section to face different areas in the oral cavity. By flexibly adjusting the position of the second connecting section, comprehensive rinsing of different areas in the oral cavity can be achieved, improving the rinsing effect. It is suitable for the complex environment in the oral cavity and can be flexibly applied to different patients.

[0022] The support tube can fix and protect the water pipe, allowing the air passage to be shaped according to the predetermined design, and can also improve the strength of the three-way gun barrel, thereby increasing its service life.

[0023] Taking a water conveyance channel as an example, the water conveyance channel is constructed with a first connecting section, a first bending section, and a second connecting section.

[0024] Taking a water pipe as an example, this application does not emphasize whether the first connecting section and the second connecting section are bendable, but it does not limit their bendability. Generally, the water pipe as a whole can be configured as a bendable structure, and either the support pipe or the air pipe can also be configured as a bendable structure as a whole; there are no restrictions here.

[0025] Continuing with the example of water pipes, this application does not limit whether the first connecting section, the first bending section, and the second connecting section are integrated.

[0026] In some embodiments, the support tube is made of stainless steel, titanium alloy or copper alloy.

[0027] In some embodiments, the air tube is made of thermoplastic elastomer (TPE), medical silicone rubber, polyurethane elastomer (PU / TPU), or polytetrafluoroethylene (PTFE).

[0028] In a further technical solution, the length of the first connecting segment is greater than the length of the second connecting segment;

[0029] The length of the third connecting segment is greater than the length of the fourth connecting segment;

[0030] The length of the fifth connecting segment is greater than the length of the sixth connecting segment.

[0031] This embodiment sets the lengths of each connecting segment relative to each other. Taking the first connecting segment and the second connecting segment as examples, the following is an explanation: Here, the first connecting segment is longer and the second connecting segment is shorter. In use, the second connecting segment goes deep into the oral cavity. Setting the second connecting segment shorter allows it to bend flexibly in the oral cavity and is also suitable for people with different oral cavity sizes, thus improving the applicability of this application.

[0032] In a further technical solution, the support pipe includes a corrugated pipe body, which constitutes the second bending section.

[0033] The corrugated tube's cross-section has wavy edges, which helps reduce the velocity of air and water flow, preventing these high speeds from affecting the patient's experience. More specifically, the corrugated structure of the tube buffers fluid impact and reduces pressure fluctuations caused by high-speed water or airflow.

[0034] The periodic corrugated structure of the corrugated pipe enhances turbulence intensity by inducing secondary flows (such as lateral vortices) and flow separation, thereby reducing biofilm adhesion, extending disinfection cycles, and lowering maintenance costs. Furthermore, the secondary flow allows water to spread over a wider area during rinsing, reducing residue in dead zones (similar to the deep cleaning effect of acoustic vibration rinsing technology) and improving rinsing uniformity.

[0035] The corrugated structure of the bellows absorbs high-frequency vibrations (such as the acoustic energy of an ultrasonic tip), reducing the mechanical impact of the instrument on the patient's teeth and improving the patient experience. Through the acoustic damping effect of the corrugated structure, the amplitude of airflow whistling can be reduced; according to tests, this can be reduced by 20 dB, further enhancing the patient experience.

[0036] The surface area of ​​a corrugated pipe is larger than that of a smooth pipe. For example, the surface area of ​​a corrugated pipe can be 40% larger than that of a smooth pipe. This increases the heat dissipation area and reduces heat accumulation (especially suitable for conveying physiologically warm water heated to 37°C).

[0037] In a further technical solution, the first connecting segment includes a first connecting sub-segment, a first bending sub-segment, and a second connecting segment connected in sequence, wherein the first connecting sub-segment is connected to the first bending segment;

[0038] The third connecting segment includes a third connecting sub-segment, a second bending sub-segment, and a fourth connecting segment connected in sequence, wherein the third connecting segment is connected to the second bending segment;

[0039] The fifth connecting segment includes a fifth connecting sub-segment, a third bending sub-segment, and a sixth connecting segment connected in sequence, wherein the fifth connecting segment is connected to the third bending segment;

[0040] The first bending segment, the second bending segment, and the third bending segment are configured correspondingly and all can be bent.

[0041] The first, third, and fifth connector segments are configured accordingly.

[0042] The second, fourth, and sixth connector segments are configured accordingly.

[0043] The first, second, and third bend segments are set accordingly. The settings for the second and third bend segments facilitate bending the first bend segment.

[0044] The water conveyance channel has two openings, one of which is located in the second connecting section and the other is located in the second connecting subsection.

[0045] The above-described implementation achieves a bendable design for the three-way gun barrel. This implementation further increases the number of bendable parts on the three-way gun barrel. Specifically, taking the first connecting segment as a control, by setting the first bending segment and the first bending sub-segment, the second connecting segment and the second connecting sub-segment can both be adjusted in position (or orientation) relative to the first connecting sub-segment. The effects are as follows: the second connecting segment and the second connecting sub-segment can be used interchangeably, improving the utilization of the three-way gun barrel; the first bending segment and the first bending sub-segment can be bent interchangeably, improving the service life of the three-way gun barrel; even when only the water supply channel opening located on the second connecting segment is used for water supply, the opening position can be adjusted more flexibly by bending the first bending segment and the first bending sub-segment, improving the operator's ease of operation; increasing the number of bendable parts can further control the flow rate of water and air, such as further avoiding poor patient experience due to excessive water flow speed, which is especially suitable for the treatment of sensitive pulp and wound care. At this time, it can also promote uniform water distribution and improve the uniformity of rinsing.

[0046] The double-bend design (total bending angle of at least 120°) allows the nozzle of the three-way gun to adapt to complex intraoral conditions, such as allowing the nozzle to bypass the buccal protuberance, thereby improving the irrigation coverage of the third molars (e.g., from 65% to 90%). This allows dentists to complete the entire dentition without frequently adjusting the patient's position. The double-bend design also adjusts the center of gravity of the three-way gun barrel, reducing the torque required for operation and alleviating the pressure on the dentist's wrist.

[0047] In a further technical solution, the length of the second connecting sub-segment is less than the length of the second connecting segment;

[0048] The length of the fourth connecting sub-segment is less than the length of the fourth connecting segment;

[0049] The length of the sixth connecting sub-segment is less than the length of the sixth connecting segment.

[0050] The second connecting segment can be used in place of the second connecting section, in which case the water outlet is the opening of the water supply channel on the second connecting segment. By making the second connecting segment shorter, it facilitates the fulfillment of needs such as cleaning deeper and more remote locations inside the mouth, or for individuals with smaller mouths (such as children), thereby further expanding the applicability of this application.

[0051] In a further technical solution, the length of the second connecting sub-segment is equal to the length of the second connecting segment;

[0052] The length of the fourth connecting segment is equal to the length of the fourth connecting segment;

[0053] The length of the sixth connecting segment is equal to the length of the sixth connecting segment.

[0054] The water infusion channel has two openings, one located in the second connecting section and the other in the second connecting sub-section. The length of the second connecting sub-section is set to be equal to the length of the second connecting section, which facilitates the alternation of the two openings and makes it easier for doctors to control the flow.

[0055] Unlike solutions where the length of the second connecting segment differs from the length of the second connecting segment, the solution in this embodiment allows the second connecting segment and the second connecting segment to be perfectly interchangeable.

[0061] The working principle and advantages of this utility model are as follows:

[0062] The first, second, and third bends can all be bent. Taking a water pipe as an example, the following is an explanation: When in use, bending the first bend creates an angle between the first and second connecting sections, allowing the second connecting section to face different areas of the oral cavity. By flexibly adjusting the position of the second connecting section, comprehensive rinsing of different areas of the oral cavity can be achieved, improving the rinsing effect. This method is suitable for the complex environment of the oral cavity and can be flexibly adapted to different patients.

[0063] The support tube can fix and protect the water pipe, allowing the air passage to be shaped according to the predetermined design, and can also improve the strength of the three-way gun barrel, thereby increasing its service life. Attached Figure Description

Detailed Implementation

[0074] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0075] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0076] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0077] See Figures 1-9 A three-way dental cleaning gun barrel includes a water pipe 1, a support pipe 2 and an air pipe 3 arranged sequentially from the inside to the outside;

[0078] The water pipe 1 has a water conveyance channel 4;

[0079] An air channel 5 is provided between the outer wall of the support tube 2 and the inner wall of the air tube 3;

[0080] The water pipe 1 has a first connecting section 11, a first bending section 12 and a second connecting section 13 connected in sequence.

[0081] The support tube 2 has a third connecting section 21, a second bending section 22 and a fourth connecting section 23 connected in sequence;

[0082] The air pipe 3 has a fifth connecting section 31, a third bending section 32 and a sixth connecting section 33 connected in sequence;

[0083] The first bending segment 12, the second bending segment 22 and the third bending segment 32 are respectively provided and can all be bent.

[0084] The first connecting segment 11, the third connecting segment 21, and the fifth connecting segment 31 are set accordingly.

[0085] The second connecting segment 13, the fourth connecting segment 23, and the sixth connecting segment 33 are set accordingly.

[0086] It should be noted that the water pipe 1 and air pipe 3 are conventional structures of a three-way gun barrel, and the water supply channel 4 and air channel 5 are also conventional designs of a three-way gun barrel. This application has not made any adjustments to the working principle of the three-way gun barrel.

[0087] The sleeve is a standard setting, and the support is also a standard setting. When sleeved, the support for the support tube 2 can refer to the existing ones, such as setting a rubber ring between the support tube 2 and the air tube 3 that does not affect the airflow, or the support tube 2 has a raised structure on its surface.

[0088] The first bend segment 12, the second bend segment 22, and the third bend segment 32 are set accordingly. The position settings for these three segments can be found in the appendix. Figure 5 The second bend segment 22 and the third bend segment 32 are configured to facilitate bending the first bend segment 12.

[0089] The first bend segment 12, the second bend segment 22, and the third bend segment 32 can all be bent. Taking water pipe 1 as an example, the following is an explanation: In use, by bending the first bend segment 12, an angle is formed between the first connecting segment 11 and the second connecting segment 13, making it easier for the second connecting segment 13 to face different areas in the oral cavity. By flexibly adjusting the position of the second connecting segment 13, comprehensive rinsing of different areas in the oral cavity can be achieved, improving the rinsing effect. It is suitable for the complex environment in the oral cavity, flexibly applicable to different patients, and adaptable to different usage needs.

[0090] The support tube 2 can fix and protect the water pipe 1, so that the air channel 5 can be formed according to the predetermined design, and can also improve the strength of the three-way gun barrel, thereby increasing its service life.

[0091] Taking water conveyance channel 4 as an example, water conveyance channel 4 is provided with first connecting section 11, first bending section 12 and second connecting section 13.

[0092] Taking water pipe 1 as an example, this application does not emphasize whether the first connecting section 11 and the second connecting section 13 are bendable, but it does not limit their bendable configuration. Generally, water pipe 1 can be configured as a bendable structure as a whole, and either the support pipe 2 or the air pipe 3 can also be configured as a bendable structure as a whole; there are no restrictions here.

[0093] Continuing with the example of water pipe 1, this application does not limit whether the first connecting section 11, the first bending section 12 and the second connecting section 13 are integrated.

[0094] In some embodiments, the support tube 2 is made of stainless steel, titanium alloy or copper alloy.

[0095] In some embodiments, the air tube 3 is made of thermoplastic elastomer (TPE), medical silicone rubber, polyurethane elastomer (PU / TPU), or polytetrafluoroethylene (PTFE).

[0096] In some embodiments, the air channel 5 is configured as a double layer.

[0097] See Figures 1-2 In this embodiment, the length of the first connecting segment 11 is greater than the length of the second connecting segment 13;

[0098] The length of the third connecting segment 21 is greater than the length of the fourth connecting segment 23;

[0099] The length of the fifth connecting segment 31 is greater than the length of the sixth connecting segment 33.

[0100] In this embodiment, the lengths of each connecting segment are set relatively. Taking the first connecting segment 11 and the second connecting segment 13 as examples, the following is an explanation: Here, the first connecting segment 11 is longer and the second connecting segment 13 is shorter. In use, the second connecting segment 13 goes deep into the oral cavity. Setting the second connecting segment 13 to be shorter makes it easier for the second connecting segment 13 to bend flexibly in the oral cavity. It is also suitable for people with different oral cavity sizes, thus improving the applicability of this application.

[0101] This embodiment does not limit the ratio of the lengths of the connecting segments, and includes... Figure 1 The setting in [the context] is a commonly used setting.

[0102] See Figures 4-5 In this embodiment, the support pipe 2 includes a corrugated pipe body 24, which constitutes the second bending section 22.

[0103] For ease of understanding, please refer to the appendix. Figure 5 The corrugated tube body 24 has a wavy edge, which reduces the air and water flow rates, preventing them from affecting the patient's experience. More specifically, the corrugated structure of the corrugated tube body 24 can buffer fluid impact and reduce pressure fluctuations caused by high-speed water or airflow.

[0104] The periodic corrugated structure of the corrugated pipe body 24 enhances turbulence intensity by inducing secondary flow (such as transverse vortices) and flow separation, thereby reducing biofilm adhesion, extending the disinfection cycle, and lowering maintenance costs. In addition, the secondary flow allows the water flow to spread to a wider area during rinsing, reducing residues in dead corners (similar to the deep cleaning effect of sonic vibration rinsing technology) and improving rinsing uniformity.

[0105] The corrugated structure of the bellows body 24 can absorb high-frequency vibrations (such as the sound wave energy of an ultrasonic tip), reducing the mechanical impact of the instrument on the patient's teeth and improving the patient experience. Through the acoustic damping effect of the corrugated structure, the amplitude of airflow whistling can be reduced; according to tests, the amplitude can be reduced by 20 dB, further improving the patient experience.

[0106] The surface area of ​​the corrugated tube body 24 is larger than that of the smooth tube body. For example, the surface area of ​​the corrugated tube body 24 can be increased by 40% compared with the smooth tube body. This increases the heat dissipation area and reduces heat accumulation (especially suitable for conveying physiological warm water heated to 37°C).

[0107] The corrugated pipe body 24 can maintain its angle after bending.

[0108] In some embodiments, the outer wall of the support tube 2 is covered with a medical-grade silicone layer or a polyurethane coating.

[0109] In some embodiments, the inner wall of the support tube 2 is covered with a PTFE (polytetrafluoroethylene) layer, which utilizes its hydrophobicity and chemical inertness to prevent liquid penetration.

[0110] See Figures 2-3 In some embodiments, the corrugated pipe body 24 is replaced by a threaded pipe body 25. The function of the threaded pipe body 25 is similar to that of the corrugated pipe body 24.

[0111] See Figure 9 In this embodiment, the first connecting segment 11 includes a first connecting sub-segment 111, a first bending sub-segment 112 and a second connecting segment 113 connected in sequence, wherein the first connecting segment 111 is connected to the first bending segment 12;

[0112] The third connecting segment 21 includes a third connecting sub-segment 211, a second bending sub-segment 212 and a fourth connecting segment 213 connected in sequence, wherein the third connecting segment 211 is connected to the second bending segment 22;

[0113] The fifth connecting segment 31 includes a fifth connecting sub-segment 311, a third bending sub-segment 312 and a sixth connecting segment 313 connected in sequence, wherein the fifth connecting segment 311 is connected to the third bending segment 32;

[0114] The first bending segment 112, the second bending segment 212 and the third bending segment 312 are correspondingly provided and all can be bent.

[0115] The first connecting sub-segment 111, the third connecting sub-segment 211, and the fifth connecting sub-segment 311 are configured accordingly.

[0116] The second connecting sub-segment 113, the fourth connecting sub-segment 213, and the sixth connecting sub-segment 313 are configured accordingly.

[0117] The first bend segment 112, the second bend segment 212, and the third bend segment 312 are set accordingly. The position settings for these three segments can be found in the appendix. Figure 9 The second bend segment 212 and the third bend segment 312 are configured to facilitate bending the first bend segment 112.

[0118] The water conveyance channel 4 has two openings, one of which is located in the second connecting section 13 and the other is located in the second connecting subsection 113.

[0119] The above embodiment achieves a bendable design for the three-way gun barrel. This embodiment further increases the number of bendable parts on the three-way gun barrel. Specifically, taking the first connecting segment 111 as a reference, through the setting of the first bending segment 12 and the first bending sub-segment 112, the second connecting segment 13 and the second connecting sub-segment 113 can both be adjusted in position (or in orientation) relative to the first connecting segment 111, with the following effect:

[0120] The second connecting section 13 and the second connecting subsection 113 can be used interchangeably, which improves the utilization of the three-way gun barrel;

[0121] The first bending section 12 and the first bending sub-section 112 can be bent interchangeably, which improves the service life of the three-way gun barrel;

[0122] Even when only the opening on the second connecting section 13 of the water supply channel 4 is used for water supply, the position of this opening can be adjusted more flexibly by bending the first bending section 12 and the first bending sub-section 112, which improves the convenience of operation for the operator. Increasing the number of bendable parts can further control the flow rate of water and air, which can further avoid poor patient experience due to excessive water flow. It is especially suitable for the treatment of sensitive pulp and wound care. At this time, it can also promote the uniform distribution of water flow and improve the uniformity of rinsing.

[0123] The double-bend design (total bending angle of at least 120°) allows the nozzle of the three-way gun to adapt to complex intraoral conditions, such as allowing the nozzle to bypass the buccal protuberance, thereby improving the irrigation coverage of the third molars (e.g., from 65% to 90%). This allows dentists to complete the entire dentition without frequently adjusting the patient's position. The double-bend design also adjusts the center of gravity of the three-way gun barrel, reducing the torque required for operation and alleviating the pressure on the dentist's wrist.

[0124] In this embodiment, the length of the second connecting segment 113 is less than the length of the second connecting segment 13;

[0125] The length of the fourth connecting segment 213 is less than the length of the fourth connecting segment 23;

[0126] The length of the sixth connecting segment 313 is less than the length of the sixth connecting segment 33.

[0127] This embodiment is not illustrated in the accompanying drawings.

[0128] The second connecting segment 113 can be used in place of the second connecting section 13, in which case the water outlet is the opening of the water supply channel 4 on the second connecting segment 113. By making the second connecting segment 113 shorter, it facilitates the fulfillment of needs such as cleaning deeper and more remote locations inside the mouth, or for individuals with smaller mouths (such as children), thereby further expanding the applicability of this application.

[0129] This embodiment does not limit whether the ports of the second connecting sub-segment 113, the fourth connecting sub-segment 213, and the sixth connecting sub-segment 313 are set flush; they can be adjusted according to actual needs. In some embodiments, the ports of the three are set flush.

[0130] See Figures 6-7 In this embodiment, the length of the second connecting segment 113 is equal to the length of the second connecting segment 13;

[0131] The length of the fourth connecting segment 213 is equal to the length of the fourth connecting segment 23;

[0132] The length of the sixth connecting segment 313 is equal to the length of the sixth connecting segment 33.

[0133] The water delivery channel 4 has two openings, one of which is located in the second connecting section 13 and the other is located in the second connecting sub-section 113. The length of the second connecting sub-section 113 is set to be equal to the length of the second connecting section 13, which facilitates the alternation of the two and makes it easier for doctors to control.

[0134] Unlike schemes where the length of the second connecting segment 113 differs from the length of the second connecting segment 13, the scheme in this embodiment allows the second connecting segment 113 and the second connecting segment 13 to be perfectly interchangeable.

[0135] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
