Description

Technical Field

[0001] This utility model relates to the field of oral medical device technology, and in particular to a tracheal assembly for a scanning head, a scanning head, and an oral scanning system. Background Technology

[0002] A digital impression scanner, also known as a dental scanner, is a device that uses an insertion optical scanning head to directly scan the inside of a patient's mouth, acquiring three-dimensional morphological and color texture information of the surfaces of soft and hard tissues such as teeth, gums, and mucous membranes. Current scanners typically have a flexible tubing located on one side of the scanning head. However, due to the good flexibility of the tubing, it is easily shaken during use, interfering with the normal operation of the scanner and thus affecting the scanning results. Utility Model Content

[0003] In view of the above, it is necessary to propose a tracheal assembly for a scanning head, a scanning head, and an oral cavity scanning system to improve scanning results.

[0004] A first aspect of this application provides a tracheal assembly for a scanning head, comprising: a trachea including a flexible tube and a rigid tube, the flexible tube being connected to and communicating with one end of the rigid tube, the flexible tube being located on one side of a scanning host, and the rigid tube being used to connect to a scanning head body to guide fluid flow at a scanning port of the scanning head body; and an adapter, one end of which is detachably connected to and communicating with the end of the flexible tube away from the rigid tube, and the other end of which is used to connect to a dental chair.

[0005] The endotracheal assembly for the scanning head in this application combines a flexible tube and a rigid tube. The flexibility of the flexible tube allows for flexible placement on the scanning host, while the rigidity of the rigid tube ensures stability on the scanning head body. This allows the endotracheal assembly to adapt to different usage environments and needs, preventing the tube from shaking during use and interfering with the normal operation of the oral scanning system, thus improving the scanning effect. Furthermore, the fluid guided by the rigid tube can disperse debris and other interfering factors that affect the scanning data, and dynamically disperse the gingiva to fully expose the subgingival shoulder, thereby acquiring three-dimensional morphological data of the tooth margins in the previously invisible subgingival region. In addition, the adapter design makes the connection between the flexible tube and the dental chair detachable. This design not only facilitates installation and replacement but also improves the maintenance convenience of the entire oral scanning system.

[0006] In some possible implementations, the air tube further includes a bent tube extending into the scanning head body, the bent tube being disposed at the end of the rigid tube away from the flexible tube, the bent tube having an air outlet whose inner diameter gradually decreases along the jet direction.

[0007] In some possible implementations, the trachea further includes a transition tube, the two ends of which are respectively connected to the rigid tube and the flexible tube, and the transition tube is flexible and located at the connection between the scanning host and the scanning head body.

[0008] In some possible implementations, the scanning head body is provided with a reflector, the bent tube is disposed on one side of the reflector, and the outer periphery of the bent tube is provided with a side nozzle communicating with the air jet, the side nozzle being disposed towards the reflector.

[0009] In some possible implementations, the side nozzle has a fan-shaped cross-section, and the angle between the spray direction of the side nozzle and the reflector is greater than or equal to 10° and less than or equal to 45°.

[0010] In some possible implementations, the adapter includes an adapter body, an air inlet pipe, and an air outlet pipe. The air inlet pipe and the air outlet pipe are respectively disposed on opposite sides of the adapter body and are connected to each other. The air outlet pipe is detachably connected to the air pipe, and the air inlet pipe is connected to the dental chair.

[0011] In some possible implementations, the adapter further includes a sealing gasket, which is sleeved on the outer periphery of the air inlet pipe and connected to the side of the adapter opposite to the air outlet pipe; the outer periphery of the air outlet pipe is provided with multiple stepped structures, which are spaced apart along the air outlet direction of the air outlet pipe.

[0012] In some possible implementations, the tracheal assembly further includes at least one first fixing member disposed on the scanning head body, the rigid tube being detachably disposed on the first fixing member.

[0013] In some possible implementations, the first fastener includes a first component for connecting the scanning head body, the first component having a first groove on the side opposite to the scanning head, and the rigid tube being engaged in the first groove.

[0014] In some possible implementations, the first fastener further includes a second component, one side of which has a second groove, and one end of the second component is rotatably connected to the first component. The second component can be opened or closed on the first component. When the first component and the second component are closed together, the rigid tube is engaged in the first groove and the second groove.

[0015] In some possible implementations, the tracheal assembly further includes at least one second fastener disposed on the scanning host, the hose being detachably disposed on the second fastener.

[0016] A second aspect of this application provides a scanning head, the scanning head including a scanning head body and any of the above-mentioned tracheal assemblies for the scanning head, the tracheal assemblies being disposed on one side of the scanning head body.

[0017] The scanning head of this application features a combination of flexible and rigid tubing. The flexibility of the flexible tubing allows for flexible placement on the scanning host, while the rigidity of the rigid tubing ensures stability on the scanning head body. This allows the tubing to adapt to different usage environments and needs, preventing the tubing from shaking during use and interfering with the normal operation of the oral scanning system, thus improving the scanning effect. Furthermore, the fluid guided by the rigid tubing can disperse debris and other interfering factors that affect the scanning data, and dynamically disperse the gingiva to fully expose the subgingival shoulder, thereby acquiring three-dimensional morphological data of the tooth margins in the previously invisible subgingival region. In addition, the adapter design makes the connection between the flexible tubing and the dental chair detachable. This design not only facilitates installation and replacement but also improves the overall ease of maintenance of the oral scanning system.

[0018] In some possible implementations, the scanning head body is a structure made of printing material.

[0019] A third aspect of this application provides an oral cavity scanning system, comprising: the aforementioned scanning head; a scanning host connected to one end of the scanning head; a data processing device connected to the scanning host, the data processing device receiving images recorded by the scanning host and analyzing and calculating three-dimensional morphological data of the patient's oral cavity; and a dental chair connected to the tracheal assembly.

[0020] The oral scanning system of this application utilizes a combination of flexible and rigid tubing. The flexibility of the flexible tubing allows for flexible placement on the scanning host, while the rigidity of the rigid tubing ensures stability on the scanning head. This allows the tubing to adapt to different usage environments and needs, preventing the tubing from shaking during use and interfering with the normal operation of the oral scanning system, thus improving the scanning effect. Furthermore, the fluid guided by the rigid tubing can disperse debris and other interfering factors that affect the scanning data, and dynamically disperse the gingiva to fully expose the subgingival shoulder, thereby acquiring three-dimensional morphological data of the tooth margins in areas not visible below the gum line. In addition, the adapter design makes the connection between the flexible tubing and the dental chair detachable. This design not only facilitates installation and replacement but also improves the overall ease of maintenance of the oral scanning system.

[0021] In some possible implementations, the oral scanning system further includes: a dental three-way gun, connected to the dental chair and the tracheal assembly respectively, for controlling whether the dental chair supplies air to the tracheal assembly; or, a foot switch, connected to the dental chair and configured to control whether the dental chair supplies air to the tracheal assembly.

Detailed Implementation

[0034] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0035] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0036] Reference Figure 1 and Figure 2 The first aspect of this application provides a tracheal assembly 100 for a scanning head 400. The scanning head 400 includes a scanning head body 200 and a reflector 300. The scanning head body 200 has an inner cavity 210, and one end of the scanning head body 200 has a scanning port 220 communicating with the inner cavity 210. The other end of the scanning head body 200 is connected to a scanning host 500, and the reflector 300 is disposed at the scanning port 220. The tracheal assembly 100 includes a trachea 10 and an adapter 20.

[0037] The trachea 10 includes a flexible tube 11 and a rigid tube 12. The flexible tube 11 is connected to and communicates with one end of the rigid tube 12. The flexible tube 11 is located on one side of the scanning host 500. The rigid tube 12 is used to connect to the scanning head body 200 to guide fluid flow at the scanning port 220 of the scanning head body 200. The rigid tube 12 is located on one side of the scanning head body 200. One end of the adapter 20 is detachably connected to and communicates with the end of the flexible tube 11 away from the rigid tube 12. The other end of the adapter 20 is used to connect to the dental chair 600.

[0038] The tracheal assembly 100 of this application blows air into the teeth and gums through the trachea 10 during use, thereby opening the gums and exposing the subgingival tissue. This allows for clear scanning of the subgingival tissue and acquisition of clear images of the subgingival tissue. The air blowing method is painless for the patient and easy to operate. By designing the trachea 10 as a combination of a flexible tube 11 and a rigid tube 12, the flexibility of the flexible tube 11 allows for flexible placement on the scanning host 500, while the rigidity of the rigid tube 12 ensures stability on the scanning head body 200. This allows the trachea 10 to adapt to different usage environments and needs, preventing the trachea 10 from shaking during use and interfering with the normal operation of the oral cavity scanning system 1000, thus improving the scanning effect of the oral cavity scanning system 1000. Furthermore, the fluid guided by the rigid tube 12 can blow away debris and other interfering factors that affect the scanning data, and dynamically disperse the gums to fully expose the subgingival shoulder, thereby acquiring three-dimensional morphological data of the tooth edge lines in the previously invisible subgingival portion. In addition, the design of the adapter 20 makes the connection between the hose 11 and the dental chair 600 detachable. This design not only facilitates installation and replacement, but also improves the maintenance convenience of the entire oral scanning system 1000.

[0039] It should be noted that the tracheal assembly 100, scanning head 400 or scanner of this application can be used not only in the field of oral scanning, but also in the field of industrial scanning, such as acquiring data of industrial products and equipment, especially data inside holes. It can also be used in the field of facial scanners and professional scanners, and can realize the three-dimensional reconstruction of objects or scenes such as faces, bodies, cultural relics, works of art, prostheses, medical devices, buildings.

[0040] Please refer to the above as well. Figure 3 and Figure 4 The trachea 10 also includes a bent tube 13 extending into the scanning head body 200. The bent tube 13 is located at the end of the rigid tube 12 away from the flexible tube 11. The bent tube 13 has an air outlet 131, the inner diameter of which gradually decreases along the jet direction. The air outlet 131 can blow air out from the scanning port 220. It can be understood that both the rigid tube 12 and the flexible tube 11 have air passages communicating with the air outlet 131 in the bent tube 13. In this way, the air pressure when the air is blown out can be increased, which can ensure the force of the airflow blowing towards the gums. By extending the bent tube 13 into the scanning head body 200, the bent tube 13 can be protected, and air can be blown into the teeth and gums through the bent tube 13, thereby opening the gums and exposing the tissue below the gums. This allows for clear scanning of the subgingival tissue and acquisition of clear images of the subgingival tissue. The air blowing method is painless for the patient and convenient to operate.

[0041] The trachea 10 also includes a transition tube 14, with its two ends connected to a rigid tube 12 and a flexible tube 11, respectively. The transition tube 14 is flexible and located at the connection point between the scanning host 500 and the scanning head body 200. By connecting the two ends of the transition tube 14 to the rigid tube 12 and the flexible tube 11, the trachea assembly 100 can adapt to the needs of different parts. The flexible design of the transition tube 14 increases the flexibility of the trachea assembly 100, allowing it to adapt to different usage environments and angle requirements, especially at the connection point between the scanning host 500 and the scanning head body 200. This design can reduce the impact of space constraints on the layout of the trachea assembly 100.

[0042] A bent tube 13 is disposed on one side of the reflector 300. A side nozzle 132 communicating with the air jet 131 is opened on the outer periphery of the bent tube 13, and the side nozzle 132 is positioned facing the reflector 300. When the air jet 131 ejects airflow, the airflow can blow towards the reflector 300 and out of the scanning port 220. The airflow blowing towards the reflector 300 can blow away the saliva or mist remaining on the reflector 300, preventing the saliva or mist on the reflector 300 from affecting the scanning accuracy. When the airflow blows out from the scanning port 220, it can also blow away the saliva splashed from the oral cavity and blow it towards the gums on both sides of the teeth. Furthermore, when saliva drips onto the reflector 300, the airflow can change the trajectory of the saliva, blowing it away from the reflector 300 and out of the inner cavity 210 from the scanning port 220. The air film formed on the reflector 300 can prevent saliva from dripping onto the reflector 300 and blow it away from the reflector 300, effectively reducing the risk of reduced scanning accuracy caused by saliva dripping onto the reflector 300, improving the reliability of the scanning head 400, and ensuring the scanning accuracy of the scanning head 400.

[0043] The angle β between the jet direction of the side nozzle 132 and the reflector 300 is greater than or equal to 10° and less than or equal to 45°. For example, the angle β between the jet direction of the side nozzle 132 and the reflector 300 can be 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, or 45°.

[0044] By setting the angle β between the jet direction of the side nozzle 132 and the reflector 300 to be greater than or equal to 10° and less than or equal to 45°, the airflow intensity of the part blowing towards the scanning port 220 and the airflow intensity of the part blowing towards the reflective surface can be taken into account. This allows the airflow ejected from the side nozzle 132 to effectively and reliably blow away the saliva dripping onto the reflector 300, and effectively and reliably blow out the saliva falling into the inner cavity 210, preventing the saliva on the reflector 300 from affecting the scanning accuracy of the scanner.

[0045] The side nozzle 132 has a fan-shaped cross-section. This allows the gas ejected from the side nozzle 132 to form a fan-shaped blowing area 1321, which more comprehensively covers the reflector 300, thereby more effectively preventing saliva from dripping onto the reflector 300 and improving the reliability of the scanning head 400.

[0046] Reference Figure 5 and Figure 6 The adapter 20 includes an adapter body 21, an inlet pipe 22, and an outlet pipe 23. The inlet pipe 22 and the outlet pipe 23 are respectively located on opposite sides of the adapter body 21 and are connected. The outlet pipe 23 is detachably connected to the air tube 10, and the inlet pipe 22 is connected to the dental chair 600. One end of the adapter 20 is detachably connected to the flexible hose 11, and the other end is used to connect to the dental chair 600. This design allows for flexible connection between the air tube assembly 100 and the scanning host 500 and the dental chair 600. The inlet pipe 22 and the outlet pipe 23 are respectively located on opposite sides of the adapter body 21 and are connected. This structural design ensures that gas can flow smoothly inside the adapter 20, thereby forming a stable fluid flow at the scanning port 220 of the scanning head body 200. The presence of the adapter body 21 provides a robust structure, ensuring the stability and reliability of the air tube assembly 100 during connection and use.

[0047] The adapter 20 also includes a sealing gasket 24, which is fitted around the outer periphery of the inlet pipe 22 and connected to the side of the adapter body 21 opposite to the outlet pipe 23. The main function of the sealing gasket 24 is to provide an airtight connection and prevent gas leakage. In the adapter 20, the sealing gasket 24 is fitted around the outer periphery of the inlet pipe 22 and connected to the side of the adapter body 21 opposite to the outlet pipe 23. This design ensures a tight seal at the connection between the inlet pipe 22 and the dental chair 600, preventing gas leakage. In medical or high-precision scanning equipment, the sealing gasket 24 can prevent contaminants from entering the system and maintain the purity of the gas.

[0048] The outer periphery of the air outlet pipe 23 is provided with multiple stepped structures 231, which are spaced apart along the air outlet direction of the air outlet pipe 23. The multiple stepped structures 231 can increase the friction between the air outlet pipe 23 and the hose 11, making the connection between the air outlet pipe 23 and the hose 11 more stable.

[0049] The tracheal assembly 100 also includes at least one first fixing member 30 disposed on the scanning head body 200. The rigid tube 12 is detachably disposed on the first fixing member 30. The first fixing member 30 can be one, two, or three, but is not limited to these. The first fixing member 30 provides a stable connection point, allowing the rigid tube 12 to be reliably connected to the scanning head body 200, ensuring the stability and reliability of the tracheal assembly 100 during use. Since the rigid tube 12 is detachably disposed on the first fixing member 30, it can be easily removed or installed from the first fixing member 30 when replacement or maintenance is required, improving maintenance convenience. The use of the first fixing member 30 reduces the risk of cross-contamination, especially in medical environments, where single-use ensures cleanliness and safety for each use. The shape of the first fixing member 30 can be circular or square, arranged around the scanning head 400. The first fixing member 101 and the scanning head body 200 can be detachably connected, such as by snap-fit ​​or bolt connection, or they can be integrally formed.

[0050] Reference Figure 7 The first fixing member 30 includes a first component 31 for connecting the scanning head body 200. A first groove 311 is formed on the side of the first component 31 facing away from the scanning head 400, and the rigid tube 12 is fitted into the first groove 311, which is concave-arc shaped. The first fixing member 30, through the design of the first groove 311, can stably fix the rigid tube 12 to the scanning head body 200, ensuring that the tracheal assembly 100 will not shift due to movement or vibration during use, thereby guaranteeing the stability and reliability of the tracheal assembly 100. The design of the rigid tube 12 being detachably mounted on the first fixing member 30 allows for quick and convenient removal of the rigid tube 12 when the tracheal assembly 100 needs to be replaced or maintained, improving the convenience of maintenance.

[0051] The first fixing member 30 also includes a second component 32. A second groove 321 is provided on one side of the second component 32. One end of the second component 32 is rotatably connected to the first component 31. The second component 32 can be opened or closed on the first component 31. When the first component 31 and the second component 32 are closed together, the rigid tube 12 is locked in the first groove 311 and the second groove 321. Through the rotatable connection and the fastening design of the first component 31 and the second component 32, the rigid tube 12 can be more firmly fixed, ensuring that the airway assembly 100 will not be displaced or fall off due to external forces during use.

[0052] The hose 11 is located on one side of the scanning host 500. The hose 11 and the scanning host 500 may be unconnected or detachably connected. In one embodiment, the endotracheal assembly 100 further includes at least one second fixing member disposed on the scanning host 500. The hose 11 is detachably disposed on the second fixing member. The second fixing member may be one, two, or three, but is not limited thereto. Specifically, the second fixing member may be a snap-fit.

[0053] The scanning host 500 can be wired or wireless. When the scanning host 500 is wired, the second fixing component can be set on the wiring harness of the scanning host 500. When the scanning host 500 is wireless, the second fixing component is set on the body of the scanning host 500. The second fixing component and the scanning host 500 can be detachably connected, such as by a snap-fit ​​connection or a bolt connection, or they can be integrally formed.

[0054] Reference Figure 8 A second aspect of this application provides a scanning head 400, including a scanning head body 200 and an airway assembly 100, the airway assembly 100 being disposed on one side of the scanning head body 200. The scanning head body 200 can be made of a printing material, such as resin or ceramic, to eliminate the problem of static electricity causing interruption of the operation of the oral scanning system 1000; the scanning head body 200 can also be a plastic structure, and can be a reusable structure or a disposable structure. Thus, the disposable structure is more convenient and hygienic to use.

[0055] During use, the scanning head 400 of this application blows air into the teeth and gums through the trachea 10, thereby opening the gums and exposing the tissue beneath the gums. This allows for clear scanning of the subgingival tissue and acquisition of clear images of the subgingival tissue. The air blowing method is painless for the patient and easy to operate. By designing the trachea 10 as a combination of a flexible tube 11 and a rigid tube 12, the flexibility of the flexible tube 11 allows for flexible placement on the scanning host 500, while the rigidity of the rigid tube 12 ensures stability on the scanning head body 200. This allows the trachea 10 to adapt to different usage environments and needs, preventing the trachea 10 from shaking during use and interfering with the normal operation of the oral cavity scanning system 1000, thus improving the scanning effect of the oral cavity scanning system 1000. Furthermore, the fluid guided by the rigid tube 12 can disperse debris and other interfering factors that affect the scanning data, and dynamically disperse the gums to fully expose the subgingival shoulder, thereby acquiring three-dimensional morphological data of the tooth edge lines in the previously invisible subgingival portion. In addition, the design of the adapter 20 makes the connection between the hose 11 and the dental chair 600 detachable. This design not only facilitates installation and replacement, but also improves the maintenance convenience of the entire oral scanning system 1000.

[0056] Please continue to refer to Figure 8 The third aspect of this application provides an oral cavity scanning system 1000, including a scanning head 400, a scanning host 500, a data processing device, and a dental chair 600. The scanning host 500 is detachably connected to one end of the scanning head 400; the data processing device is connected to the scanning host 500, and the data processing device analyzes and calculates the three-dimensional morphological data of the patient's oral cavity by receiving images recorded by the scanning host 500; the dental chair 600 is connected to the tracheal assembly 100.

[0057] In some embodiments, the oral scanning system 1000 further includes a dental three-way gun connected to the dental chair 600 and the tracheal assembly 100, and configured to control whether the dental chair 600 supplies air to the tracheal assembly 100. In use, the scanning head 400 can be manually controlled to scan while the dental three-way gun controls the dental chair 600 to supply air to or de-air the tracheal assembly 100.

[0058] In some embodiments, the oral scanning system 1000 further includes a foot switch 700, which is connected to the dental chair 600 and the tracheal assembly 100 respectively, and is configured to control whether the dental chair 600 supplies air to the tracheal assembly 100. The dental chair 600 has multiple interfaces, and the tracheal assembly 100 can connect to any of these interfaces. In use, the system can be operated by a single person; that is, a doctor can manually control the scanning head 400 to scan while simultaneously using the foot switch 700 to control whether the dental chair 600 supplies air to or de-breathes the tracheal assembly 100.

[0059] By setting the dental three-way gun or foot switch 700 to supply or de-air the tracheal assembly 100, a single doctor can complete the scanning operation. This allows for the acquisition of three-dimensional morphological data of the tooth edges, which are not visible below the gum line. It achieves better scanning results in complex oral environments, improving the quality of scan data. Furthermore, it flushes saliva away from the scanning port 220, reducing or preventing saliva from dripping into the scanning head 400 and contaminating it. This allows the scanning host 500 to record clearer images, reducing the scanning time for acquiring clear images and improving scanning efficiency. The data processing equipment can then acquire more accurate tooth data, thereby more accurately calculating the three-dimensional morphological data of the patient's oral cavity. No medical staff assistance is required, making this method more practical for industrial use compared to the current method where one person controls the scanning and another controls the air supply or de-airing.

[0060] The oral scanning system 1000 of this application uses an air tube 10 to blow air into the teeth and gums during use, thereby opening the gums and exposing the subgingival tissue. This allows for clear scanning of the subgingival tissue and acquisition of clear images of the subgingival tissue. The air blowing method is painless for the patient and easy to operate. By designing the air tube 10 as a combination of a flexible tube 11 and a rigid tube 12, the flexibility of the flexible tube 11 allows for flexible placement on the scanning host 500, while the rigid tube 12 ensures stability on the scanning head body 200. This allows the air tube 10 to adapt to different usage environments and needs, preventing the air tube 10 from shaking during use and interfering with the normal operation of the oral scanning system 1000, thus improving the scanning effect of the oral scanning system 1000. Furthermore, the fluid guided by the rigid tube 12 can blow away debris and other interfering factors that affect the scanning data, and dynamically open the gums to fully expose the subgingival shoulder, thereby acquiring three-dimensional morphological data of the tooth edge lines in the previously invisible subgingival portion. In addition, the design of the adapter 20 makes the connection between the hose 11 and the dental chair 600 detachable.
