Description

Technical Field

[0001] This invention relates to the field of medical device technology, and specifically to a laser oral treatment device for use in the field of oral treatment. Background Technology

[0002] The oral cavity is the starting point of the human digestive tract. Through chewing food, teeth play a crucial role in the entire digestive process and are essential for nutrient intake. Therefore, oral health is not only a part of overall health but also inextricably linked to it. Common oral problems include tartar, periodontal disease, bacterial infections, and tooth loss. Clinically, various treatments are used to alleviate or even eliminate the negative impacts of these oral problems. Laser dental treatment devices are commonly used to address these issues.

[0003] Laser dental treatment devices utilize high-energy laser beams for oral treatment. Existing laser dental treatment devices typically include at least a YAG laser, a light transmission component, and a light-emitting tip. The YAG laser and the light-emitting tip are separate structures, optically connected by the light transmission component. The operator holds the light-emitting tip and controls the YAG laser. The laser beam travels from the YAG laser through the light transmission component to the light-emitting tip and is then emitted. This high-energy laser beam irradiates oral tissues and can be used for cleaning and sterilization, soft and hard tissue cutting, bone removal, and other procedures. It can reduce inflammation and promote the regeneration and repair of oral tissues.

[0004] Existing laser oral treatment devices can meet basic treatment needs, but due to their unreasonable structure, they suffer from problems such as low integration, difficulty in movement, and inconvenience in operation. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] The oral cavity is the starting point of the human digestive tract. Through chewing food, teeth play a crucial role in the entire digestive process and are essential for nutrient intake. Therefore, oral health is not only a part of overall health but also inextricably linked to it. Common oral problems include tartar, periodontal disease, bacterial infections, and tooth loss. Clinically, various treatments are used to alleviate or even eliminate the negative impacts of these oral problems. Laser dental treatment devices are commonly used to address these issues.

[0044] Laser dental treatment devices utilize high-energy laser beams for oral treatment. Existing laser dental treatment devices typically include at least a YAG laser, a light transmission component, and a light-emitting tip. The YAG laser and the light-emitting tip are separate structures, optically connected by the light transmission component. The operator holds the light-emitting tip and controls the YAG laser. The laser beam travels from the YAG laser through the light transmission component to the light-emitting tip and is then emitted. This high-energy laser beam irradiates oral tissues and can be used for cleaning and sterilization, soft and hard tissue cutting, bone removal, and other procedures. It can reduce inflammation and promote the regeneration and repair of oral tissues.

[0045] Existing laser oral treatment devices can meet basic treatment needs, but due to their unreasonable structure, they suffer from problems such as low integration, difficulty in movement, and inconvenience in operation.

[0046] like Figures 1 to 13 As shown, to solve the above problems, the present invention provides a laser oral treatment device, including a treatment device body 1, a laser generating component 2, a water-air nozzle assembly 3, and a gas-liquid-electric external connection component 4. The treatment device body 1 includes a supporting outer shell and a supporting inner shell, with the supporting outer shell sleeved over the supporting inner shell. The two components work together primarily to provide structural support. The laser generating component 2, the water-air nozzle assembly 3, and the gas-liquid-electric external connection component 4 are directly or indirectly disposed on the supporting outer shell or the supporting inner shell. The laser generating component 2 is used to generate a high-energy laser beam for oral treatment. The water-air nozzle assembly 3 is used to form a water-air spray for cleaning or cooling the oral cavity. The gas-liquid-electric external connection component 4 is used to connect to external gas, water, and electrical signals to ensure the normal operation of the laser oral treatment device.

[0047] like Figure 5 As shown, the laser generating assembly 2 includes a quartz glass tube 201, a light-emitting crystal 202, a pump flash lamp 203, a total internal reflection focusing layer 204, and a refractor assembly 205. The quartz glass tube 201 has a first fixed conduit 206 and a second fixed conduit 207. The light-emitting crystal 202 is fixedly disposed within the first fixed conduit 206, and a laser working medium is disposed within the light-emitting crystal 202. One end of the light-emitting crystal 202 has a total internal reflection end face, and the other end has a semi-transparent end face. The pump flash lamp 203 is fixedly disposed within the second fixed conduit 207. The total internal reflection focusing layer 204 covers the outside of the quartz glass tube 201. The quartz glass tube 201 is fixedly disposed within the inner supporting housing, and the refractor assembly 205 is fixedly disposed on the outer supporting housing. The working principle of the laser generating component 2 is as follows: Inside the quartz glass tube 201, the pump flash lamp 203 emits light in a flashing manner. After the light emitted by the pump flash lamp 203 illuminates the light-emitting crystal 202, the laser working medium inside the light-emitting crystal 202 is excited to emit laser light. At this time, the laser light is directed in its respective direction. The laser light emitted in each direction is confined within the total internal reflection focusing layer 204 and oscillates between the total internal reflection end face and the semi-transparent end face at both ends of the light-emitting crystal 202, eventually forming a high-energy laser beam with the same direction, which is emitted from the semi-transparent end face. The laser light generated by the pump flash lamp 203 and the light-emitting crystal 202 is emitted from the semi-transparent end face, refracted by the refractor assembly 205, and then emitted from the laser emission tip 303.

[0048] The water-air nozzle assembly 3 includes a water-air nozzle body 301, a tip fixing insert 302, and a laser emission tip 303. The water-air nozzle body 301 is sleeved on the supporting outer shell. A first mounting sleeve is provided inside the water-air nozzle body 301. The first mounting sleeve is located in the center of the water-air nozzle body 301 and is arranged axially. A water supply pipe, an air supply pipe, and a water-air emission hole are provided in the side wall of the water-air nozzle body 301. The water supply pipe and the air supply pipe are respectively connected to the water-air emission hole. The tip fixing insert 302 is fixedly installed in the first mounting sleeve. A second mounting sleeve is provided inside the tip fixing insert 302. The second mounting sleeve is located in the center of the tip fixing insert 302 and is arranged axially. The laser emission tip 303 is fixedly installed in the second mounting sleeve. The water supply pipe and the air supply pipe are "hidden pipes" set in the side wall of the water and air nozzle body 301. That is, when the water and air nozzle body 301 is manufactured, pipes are formed on its side wall, one or more of which serve as water supply pipes and the others as air supply pipes.

[0049] An optical fiber is embedded within the laser emission tip 303, with both ends of the fiber exposed at the ends of the tip. The orientation of the water vapor emission port is consistent with that of the laser emission tip 303. The optical fiber is distributed along the length of the laser emission tip 303. After the laser enters the optical fiber from one end, it is transmitted to the other end. Because both ends of the fiber are exposed at the ends of the laser emission tip 303, the high-energy laser beam ultimately exits from the tip, allowing the operator to perform various treatments on the patient's oral cavity. During this process, spraying water vapor from the water vapor emission port can cool and clean the patient's oral cavity.

[0050] The gas-liquid-electric external connection assembly 4 includes a connector fixing sleeve 401 and a gas-liquid-electric connection component 402. The gas-liquid-electric connection component 402 is fixedly disposed on the connector fixing part of the connector fixing sleeve 401. The gas-liquid-electric connection component 402 includes multiple gas-liquid delivery connectors 403 and multiple electrical delivery connectors 404. The gas-liquid delivery connectors 403 are connected to the water supply pipe and the air supply pipe on the water-air nozzle body 301 through water supply pipes and air supply pipes, respectively. The electrical delivery connectors 404 are connected to the light-emitting crystal 202 and the pump flash lamp 203 through conductive cables. The air supply pipe and the water supply pipe are ordinary flexible hose structures.

[0051] Both gas and liquid are fluids. After the gas and / or liquid from the outside are connected through the gas-liquid delivery connector 403, the gas enters the gas delivery pipe, and the liquid enters the water delivery pipe. The gas then enters the gas delivery pipe inside the water-air nozzle body 301 through the gas delivery pipe, and the liquid enters the water delivery pipe inside the water-air nozzle body 301 through the water delivery pipe. The gas and liquid are then mixed inside the water-air nozzle body 301 and sprayed out, thus cooling and cleaning the patient's oral cavity. In this technical solution, the liquid used for cooling is usually water.

[0052] When performing treatment using this laser oral therapy device, the specific working process is as follows: The laser generating component 2 generates a laser and forms a high-energy laser beam. The operator can use the high-energy laser beam to perform operations such as cleaning and sterilization, soft and hard tissue cutting, and bone removal in the patient's oral cavity. During the operation, component debris may be generated in the area irradiated by the high-energy laser beam, accompanied by overheating. At this time, water vapor spray can be sprayed out through the water vapor nozzle component 3 to clean and cool the corresponding area. Therefore, based on the above technical solution, the laser generating component 2, water vapor nozzle component 3, and gas-liquid-electric external connection component 4 are set in the treatment device body 1, integrating the laser generation and emission and water vapor mixing and cooling functions into one structure, meeting the basic operational needs of cleaning and sterilization, soft and hard tissue cutting, and bone removal, while having the advantages of high integration, reasonable structure, and convenient operation.

[0053] like Figure 3 and Figure 4 As shown, preferably, the supporting outer shell includes a front shell and a rear shell. The water / air nozzle assembly 3 is fixedly disposed within the front shell. A quick-release sleeve 5 is provided on the front shell, and a quick-release plug 6 is provided on the rear shell. The quick-release sleeve 5 has a cylindrical structure, and the quick-release plug 6 has a cylindrical structure. The quick-release sleeve 5 and the quick-release plug 6 are coaxially arranged. The purpose of including a front shell and a rear shell in the supporting outer shell is to allow this laser oral treatment device to be assembled or disassembled according to actual needs, in order to meet the requirements of normal use and post-use disinfection. The use of a front shell and a rear shell to form the supporting outer shell is existing technology. This technical solution does not conduct innovative research on this point, nor does it elaborate on it in conjunction with the accompanying drawings. In addition, when analyzing this technical solution, the front shell and quick-release sleeve are placed in front, and the rear shell and quick-release plug are placed behind, with the laser emission direction as a reference.

[0054] The quick-release sleeve 5 is provided with an elastic snap-fit ​​component, and the quick-release plug 6 is provided with a snap-fit ​​engagement component. The quick-release plug 6 is detachably inserted into the quick-release sleeve 5 through the engagement of the elastic snap-fit ​​component and the snap-fit ​​engagement component. In this technical solution, the quick-release plug 6 and the water / air nozzle body 301 generally achieve the technical purpose of transmitting water and air from back to front by providing a "concealed pipe" in the side wall in conjunction with other structures.

[0055] Based on the above structure, with the quick-release sleeve 5 and quick-release plug 6 fixed to the front and rear housings respectively, an elastic snap-fit ​​component and a snap-fit ​​engagement component are provided. The quick-release plug 6 can be detached and inserted into the quick-release sleeve 5 through the cooperation of the elastic snap-fit ​​component and the snap-fit ​​engagement component. When needed, the quick-release sleeve 5 and quick-release plug 6 are plugged into each other and fixed to emit laser for treatment. When disinfection is needed, the quick-release sleeve 5 and quick-release plug 6 are separated to meet the needs of fixing or disassembling before and after use. This makes it convenient for operators to assemble the water and air nozzle assembly 3 through the cooperation of the quick-release sleeve 5 and quick-release plug 6 during normal use. After use, it can be decomposed and disinfected to effectively prevent cross-infection.

[0056] like Figure 3 and Figure 4 As shown, preferably, the elastic snap-fit ​​assembly includes an elastic clamp 501 and three rigid beads 502. The elastic clamp 501 is formed by bending a long metal sheet into an arc shape. The elastic clamp 501 has three bead positioning through holes 503; of the three bead positioning through holes 503, one is a circular through hole, and the other two are elongated through holes. The circular through hole is located at the midpoint of the elastic clamp 501, and the two elongated through holes are symmetrically arranged on both sides of the circular through hole. The elastic clamp 501 is formed by bending a long metal sheet into an arc shape, with an opening at each end of the long metal sheet. This opening indicates that the ends are not connected, and the long metal sheet does not form a closed circle. When the long metal sheet is bent into an arc shape and the ends are not connected, the long metal sheet itself has elasticity; that is, when this arc shape is subjected to external force, its own elastic force will drive it to return to its original state. This technical solution utilizes the characteristic of elastic clamps to provide the elastic force required for quick assembly and disassembly.

[0057] The quick-release sleeve 5 has three ball-bead movable through holes 504 on its side wall, which are disposed through the side wall of the quick-release sleeve 5. A ball-bead limiting ring 505 is disposed at the bottom of each ball-bead movable through hole 504, located on the inner side of the side wall of the quick-release sleeve 5. The inner diameter of the ball-bead limiting ring 505 is smaller than the radius of the rigid ball 502. The rigid ball 502, the ball-bead movable through hole 504, and the ball-bead positioning through hole 503 correspond one-to-one. The rigid ball 502... 2. The ball is movably disposed within the ball movable through hole 504. The two sides of the hard ball 502 abut against the ball positioning through hole 503 and the ball limiting ring 505, respectively. The elastic clamp 501 is sleeved on the quick-release sleeve 5. The elastic clamp 501 applies a spring force to the multiple hard balls 502 in the axial direction of the quick-release sleeve 5. The snap-fit ​​assembly is a ball snap-fit ​​groove 601 disposed on the quick-release plug 6. The ball snap-fit ​​groove 601 is disposed circumferentially on the outer side of the quick-release plug 6.

[0058] When the quick-release plug 6 is fixed to the quick-release sleeve 5, the elastic clamp 501 fixes the hard ball 502 in the ball retaining groove 601; when the quick-release plug 6 and the quick-release sleeve 5 are subjected to external force and move relative to each other, the hard ball 502 is forced to open the elastic clamp 501 and slide out from the ball retaining groove 601.

[0059] Based on the above structure, the working principle of the quick-release structure is analyzed as follows: When the quick-release plug 6 is fixed on the quick-release sleeve 5, the elastic clamp 501 uses its own elasticity to fix the hard ball 502 in the ball retaining groove 601. The hard ball 502 is fixed in the ball retaining groove 601, and correspondingly, the quick-release plug 6 and the quick-release sleeve 5 are combined into a whole structure. When it is necessary to separate the quick-release plug 6 and the quick-release sleeve 5 for quick disassembly, the operator applies external force, causing the quick-release plug 6 and the quick-release sleeve 5 to tend to separate from each other. At this time, the external force will drive the hard ball 502 to slide out of the ball retaining groove 601. During this process, the hard ball 502 expands the elastic clamp 501, overcomes the elastic force of the elastic clamp 501, and gradually slides out of the ball retaining groove 601. After the hard ball 502 leaves the ball retaining groove 601, the quick-release plug 6 and the quick-release sleeve 5 are separated from each other. When it is necessary to quickly install the quick-release plug 6 onto the quick-release sleeve 5, the operator provides external force, causing the quick-release plug 6 and the quick-release sleeve 5 to tend to interlock. During this process, the rigid ball 502 expands the elastic clamp 501, overcomes the elastic force of the elastic clamp 501, and gradually embeds itself into the ball engagement groove 601. After the rigid ball 502 is embedded into the ball engagement groove 601, the quick-release plug 6 and the quick-release sleeve 5 are interlocked and fixed.

[0060] Based on the above structure, a long metal sheet is bent into an arc shape, forming an opening in the arc shape. The long metal sheet utilizes its own elasticity to form an elastic clamp 501, pressing multiple hard balls 502 into the ball-locking groove 601. When no external force is applied, the hard balls 502 are engaged in the ball-locking groove 601. When an external force is applied, they can roll out of the ball-locking groove 601. An elastic locking assembly is formed by one elastic clamp 501 and three hard balls 502. A locking assembly is formed by recessing the ball-locking groove 601 inward on the quick-release plug 6. The quick-release function is achieved by using a simple elastic structure.

[0061] like Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the supporting inner shell includes a front internal support assembly 101, a rear internal support assembly 102, and a laser cavity support cylinder 103. The front internal support assembly 101 is fixedly disposed at the front end of the laser cavity support cylinder 103, and the rear internal support assembly 102 is fixedly disposed at the rear end of the laser cavity support cylinder 103. The quartz glass tube 201 is fixedly disposed inside the laser cavity support cylinder 103. More specifically, the front internal support assembly 101 has a crystal front end fixing through hole 104 and a flash lamp front end fixing through hole 105, and the rear internal support assembly 102 has a crystal rear end fixing through hole 106 and a flash lamp rear end fixing through hole 107. The two ends of the light-emitting crystal 202 are respectively disposed through the crystal front end fixing through hole 104 and the crystal rear end fixing through hole 106, and the two ends of the pump flash lamp 203 are respectively disposed through the flash lamp front end fixing through hole 105 and the flash lamp rear end fixing through hole 107.

[0062] To improve the sealing performance of this laser oral treatment device, multiple gasket pressing members 108 are provided on the front internal support assembly 101 and the rear internal support assembly 102. Gasket fixing sleeves are provided in the respective through-hole bodies of the crystal front fixing through-hole 104, the flash lamp front fixing through-hole 105, the crystal rear fixing through-hole 106, and the flash lamp rear fixing through-hole 107. A support member sealing ring is provided in the gasket fixing sleeve. The support member sealing ring is sleeved on the light-emitting crystal 202 or the pump flash lamp 203. The gasket pressing member 108 presses the support member sealing ring into the gasket fixing sleeve.

[0063] A gasket fixing sleeve is provided on the front fixing through hole 104 of the crystal, the front fixing through hole 105 of the flash lamp, the rear fixing through hole 106 of the crystal, and the rear fixing through hole 107 of the flash lamp. The through hole body on the front fixing through hole 104 of the crystal, the front fixing through hole 105 of the flash lamp, the rear fixing through hole 106 of the crystal, and the rear fixing through hole 107 of the flash lamp are coaxial cylindrical structures with their respective gasket fixing sleeves. The gasket fixing sleeve is formed by the inward indentation at the end of the through hole body, so as to facilitate the locking and fixing of the support sealing ring.

[0064] During assembly, first, the two ends of the light-emitting crystal 202 are passed through the front fixing through hole 104 and the rear fixing through hole 106 of the crystal, respectively. Then, the two ends of the pump flash lamp 203 are passed through the front fixing through hole 105 and the rear fixing through hole 107 of the flash lamp, respectively. Next, the support sealing rings are fitted onto both ends of the light-emitting crystal 202 and both ends of the pump flash lamp 203. Finally, the gasket pressing part 108 is installed. The support sealing ring will deform after being squeezed by the gasket pressing part 108, filling the space between the light-emitting crystal 202 and the through holes at both ends, and between the pump flash lamp 203 and the through holes at both ends. This achieves the technical effect of both installing and fixing the light-emitting crystal 202 and the pump flash lamp 203, and ensuring the sealing performance of the laser cavity support cylinder 103.

[0065] Based on the above structure, a supporting inner shell is formed by the front internal support component 101, the rear internal support component 102 and the laser cavity support cylinder 103. The quartz glass tube 201, the light-emitting crystal 202, the pump flash lamp 203 and other components are fixed in the supporting inner shell. Furthermore, the supporting inner shell is sealed with the support sealing ring, which can provide structural support for the internal cooling water circulation.

[0066] like Figure 8 As shown, preferably, the gasket crimping member 108 includes a crimping sleeve 109, a first fixing ear 110 and a second fixing ear 111, the first fixing ear 110 and the second fixing ear 111 being fixedly disposed on both sides of the crimping sleeve 109.

[0067] In the front internal support assembly 101, the gasket crimping member 108 is fixed to the front internal support assembly 101 by crimping bolts passing through the first fixing ear 110 and the second fixing ear 111, and the crimping sleeve 109 crimps the support member sealing ring into the corresponding gasket fixing sleeve; in the rear internal support assembly 102, the gasket crimping member 108 is fixed to the rear internal support assembly 102 by crimping bolts passing through the first fixing ear 110 and the second fixing ear 111, and the crimping sleeve 109 crimps the support member sealing ring into the corresponding gasket fixing sleeve.

[0068] Based on the above structure, a gasket pressing component 108 is formed by pressing sleeve 109, first fixing ear 110 and second fixing ear 111. The gasket pressing component 108 is used to press the support member sealing ring into the gasket fixing sleeve, which can effectively improve the sealing performance.

[0069] like Figure 2 , Figure 5 , Figure 6 , Figure 7As shown, preferably, a coolant flow connection hole is provided between the crystal front end fixing through hole 104 and the flash lamp front end fixing through hole 105; a first external pipe 112 and a second external pipe 113 are also provided outside the rear internal support assembly 102, the first external pipe 112 and the second external pipe 113 are respectively connected to the water supply pipe of the gas-liquid-electric external connection assembly 4, the first external pipe 112 is connected to the crystal rear end fixing through hole 106, and the second external pipe 113 is connected to the flash lamp rear end fixing through hole 107; the quartz glass tube 20 The two ends of 1 respectively abut against the front internal support component 101 and the rear internal support component 102. The two ends of the first fixed pipe 206 are respectively connected to the front fixed through hole 104 of the crystal and the rear fixed through hole 106 of the crystal. The two ends of the second fixed pipe 207 are respectively connected to the front fixed through hole 105 of the flash lamp and the rear fixed through hole 107 of the flash lamp. Liquid flow gaps are formed between the light-emitting crystal 202 and the first fixed pipe 206, and between the pump flash lamp 203 and the second fixed pipe 207.

[0070] In short, the light-emitting crystal 202 is fixedly disposed in the first fixed pipe 206, and the two ends of the light-emitting crystal 202 are respectively fixed to the front end fixed through hole 104 and the rear end fixed through hole 106 of the crystal; the pump flash lamp 203 is fixedly disposed in the second fixed pipe 207, and the two ends of the pump flash lamp 203 are respectively fixed to the front end fixed through hole 105 and the rear end fixed through hole 107 of the flash lamp.

[0071] A liquid cooling pipe is formed from the first external connector 112 through the crystal rear end fixing through hole 106, the first fixing pipe 206, the crystal front end fixing through hole 104, the coolant flow connection hole, the flash lamp front end fixing through hole 105, the second fixing pipe 207, the flash lamp rear end fixing through hole 107 to the second external connector 113. The liquid cooling pipe is a U-shaped pipe.

[0072] During operation, the light-emitting crystal 202 and the pump flash lamp 203 work together to generate laser light, inevitably producing heat. The liquid cooling pipe is connected to external coolant via a first external connector 112 and a second external connector 113. The coolant can enter the liquid cooling pipe through the first external connector 112 and exit through the second external connector 113, or vice versa. When the coolant flows within the first fixed pipe 206 and the second fixed pipe 207, it fully contacts the light-emitting crystal 202 and the pump flash lamp 203, thereby cooling them. In this technical solution, water is often used as the coolant.

[0073] Based on the above structure, the cooling pipe is built using the first fixed pipe 206 and the second fixed pipe 207 on the quartz glass tube 201 as the foundation. The cooling pipe is connected between the fixed through hole 104 at the front end of the crystal and the fixed through hole 105 at the front end of the flash lamp through a coolant flow connection hole. The internal support component 102 is connected to the external water supply pipe through the first external pipe 112 and the second external pipe 113. This can remove the heat generated during the operation of the laser device in a timely and efficient manner, effectively prevent overheating, and ensure the normal operation of the equipment.

[0074] like Figure 9 As shown, preferably, the outer side of the water / air nozzle body 301 protrudes outward to form a first plug washer fixing part 602, a second plug washer fixing part 603, and a third plug washer fixing part 604. The first plug washer fixing part 602, the second plug washer fixing part 603, and the third plug washer fixing part 604 are formed on the outer side of the water / air nozzle body 301 along the circumference of the water / air nozzle body 301, that is, the first plug washer fixing part 602, the second plug washer fixing part 603, and the third plug washer fixing part 604 are formed on the outer side of the water / air nozzle body 301. The fixing part 604 forms a ring-like structure on the outer surface of the water-air nozzle body 301. The first plug washer fixing part 602, the second plug washer fixing part 603, and the third plug washer fixing part 604 are equidistantly distributed along the axial direction of the water-air nozzle body 301. That is, along the length direction of the water-air nozzle body 301, the distance between the first plug washer fixing part 602 and the second plug washer fixing part 603 is equal to the distance between the second plug washer fixing part 603 and the third plug washer fixing part 604. A nozzle sealing ring 605 is fixedly provided on the first plug washer fixing part 602, the second plug washer fixing part 603, and the third plug washer fixing part 604, thereby improving the sealing performance of the device.

[0075] Another function of the first plug washer fixing part 602, the second plug washer fixing part 603, and the third plug washer fixing part 604 is to fix the nozzle sealing ring 605. When the water and air nozzle body 301 is fitted inside the treatment device housing, the water and air nozzle body 301 abuts against the treatment device housing through the first plug washer fixing part 602, the second plug washer fixing part 603, and the nozzle sealing ring 605 on the third nozzle washer.

[0076] Based on the above structure, the nozzle sealing rings 605 on the first plug washer fixing part 602, the second plug washer fixing part 603, and the third plug washer fixing part 604 abut against the inside of the treatment device housing, which can effectively ensure the sealing between the water / air nozzle body 301 and the treatment device housing, preventing water / air leakage from affecting electronic components. By providing three plug washer fixing parts, the three nozzle sealing rings 605 can significantly improve the sealing effect.

[0077] One of the functions of the first plug washer fixing part 602, the second plug washer fixing part 603, and the third plug washer fixing part 604 is to form a liquid channel and a gas channel. The water-gas nozzle body 301 forms the liquid channel by abutting against the inside of the therapeutic device housing through the nozzle sealing rings 605 on the first plug washer fixing part 602 and the second plug washer fixing part 603; the water-gas nozzle body 301 forms the gas channel by abutting against the inside of the therapeutic device housing through the nozzle sealing rings 605 on the second plug washer fixing part 603 and the third plug washer fixing part 604.

[0078] The first plug washer fixing part 602, the second plug washer fixing part 603, and the third plug washer fixing part 604 are structures that protrude from the outer side of the water-air nozzle body 301. When the water-air nozzle body 301 is fitted onto the outer shell of the therapeutic instrument, the nozzle sealing rings 605 on the first plug washer fixing part 602, the second plug washer fixing part 603, and the third plug washer fixing part 604 abut against the inner shell of the therapeutic instrument. Accordingly, a sealed channel is formed between the water-air nozzle body 301, the first plug washer fixing part 602, the second plug washer fixing part 603, and the outer shell of the therapeutic instrument, and this sealed channel serves as a liquid channel; a sealed channel is also formed between the water-air nozzle body 301, the second plug washer fixing part 603, the third plug washer fixing part 604, and the outer shell of the therapeutic instrument, and this sealed channel serves as a gas channel.

[0079] Based on the above structure, and considering the fit between the water-air nozzle body 301 and the outer shell of the therapeutic instrument, a liquid channel is formed by the nozzle sealing rings 605 on the first plug washer fixing part 602 and the second plug washer fixing part 603, and a gas channel is formed by the nozzle sealing rings 605 on the second plug washer fixing part 603 and the third plug washer fixing part 604. The liquid channel and the gas channel are cleverly separated by the first plug washer fixing part 602, the second plug washer fixing part 603 and the third plug washer fixing part 604, which were originally used for sealing and isolation, thus further simplifying the structure of this water-air mixing nozzle.

[0080] like Figure 10As shown, preferably, one end of the supporting outer shell is provided with a flexible hose sleeve 114; a protective hose 7 is sleeved on the flexible hose sleeve 114, and the water pipe, gas pipe and conductive cable are disposed inside the protective hose 7. The length of the protective hose 7 is greater than the length of the water pipe, the gas pipe and the conductive cable; a hose crimping ring 115 is provided outside the protective hose 7, and the hose crimping ring 115 crimps the protective hose 7 onto the flexible hose sleeve 114; a hose crimping outer sleeve 116 is provided on the supporting outer shell, and the hose crimping outer sleeve 116 is provided with an internal thread connection part. The hose crimping outer sleeve 116 is threadedly engaged with the external thread connection part on the supporting outer shell through its internal thread connection part, and the hose crimping outer sleeve 116 fixes the hose crimping ring 115 between the supporting outer shell and the hose crimping outer sleeve 116.

[0081] The conduit anti-pull structure in this technical solution consists of a flexible sleeve 114, a conduit protection flexible hose 7, a flexible hose crimping ring 115, and a flexible hose crimping outer sleeve 116. During installation, utilizing the deformable characteristics of the conduit protection flexible hose 7, the conduit protection flexible hose 7 is first fitted onto the flexible sleeve 114 on the supporting housing. Then, the flexible hose protection flexible hose 7 is fitted onto the flexible hose crimping ring 115. On this basis, the flexible hose crimping outer sleeve 116 is assembled onto the supporting housing using the external threaded connection and the internal threaded connection. At this time, the flexible hose crimping ring 115 crimps the conduit protection flexible hose 7 onto the flexible sleeve 114. The supporting housing and the flexible hose crimping outer sleeve 116 then confine the flexible hose crimping ring 115 between them, ensuring the crimping and fixing effect of the flexible hose crimping ring 115 on the conduit protection flexible hose 7.

[0082] Since the length of the conduit protection hose 7 is greater than the length of the cable and the water pipe, when the cable and the water pipe are subjected to external tension, the tension will act on the conduit protection hose 7. However, since the conduit protection hose 7 is fixed to the hose sleeve 114, the tension will not be transmitted to the cable and the water pipe.

[0083] Based on the above structure, the conduit protection hose 7 is sleeved on the hose sleeve sleeve 114, and the hose crimping ring 115 is sleeved on the outside of the conduit protection hose 7. After the hose crimping outer sleeve 116 is assembled on the supporting outer shell, the position of the hose crimping ring 115 can be limited. Thus, the end of the conduit protection hose 7 is fixed by the hose crimping ring 115. While ensuring the degree of freedom of operation, the anti-pull function can be achieved through a simple structure.

[0084] like Figure 11As shown, preferably, the flexible sleeve 114 includes a first snap-fit ​​cylindrical sleeve 117, a first snap-fit ​​frustum sleeve 118, a second snap-fit ​​cylindrical sleeve 119, and a second snap-fit ​​frustum sleeve 120. The first snap-fit ​​cylindrical sleeve 117, the first snap-fit ​​frustum sleeve 118, the second snap-fit ​​cylindrical sleeve 119, and the second snap-fit ​​frustum sleeve 120 are coaxial with each other. The first snap-fit ​​cylindrical sleeve 117 is located at the end away from the supporting outer shell, and the second snap-fit ​​frustum sleeve 120 is located at the end close to the supporting outer shell. The first snap-fit ​​cylindrical sleeve 117, the first snap-fit ​​frustum sleeve 118, the second snap-fit ​​cylindrical sleeve 119, and the second snap-fit ​​frustum sleeve 120 are connected end to end in sequence, and a flexible sleeve snap-fit ​​step is formed between the second snap-fit ​​cylindrical sleeve 119 and the second snap-fit ​​frustum sleeve 120.

[0085] The function of the flexible sleeve 114 is to sleeve the conduit protection flexible hose 7 and, together with the flexible hose crimping ring 115, fix the conduit protection flexible hose 7. Based on the above structure, the flexible sleeve 114 is decomposed into a first snap-fit ​​cylindrical sleeve 117, a first snap-fit ​​frustum sleeve 118, a second snap-fit ​​cylindrical sleeve 119, and a second snap-fit ​​frustum sleeve 120. A flexible hose snap-fit ​​step is formed between the second snap-fit ​​cylindrical sleeve 119 and the second snap-fit ​​frustum sleeve 120. When the flexible hose crimping ring 115 crimps the conduit protection flexible hose 7 onto the flexible hose snap-fit ​​step, the flexible hose snap-fit ​​step will cause the conduit protection flexible hose 7 to deform, which will make the fixing effect of the conduit protection flexible hose 7 better.

[0086] As described above, the function of the hose sleeve 114 is to connect the conduit and protect the hose 7. The outer diameter of the first snap-fit ​​cylindrical sleeve 117 is smaller than the outer diameter of the second snap-fit ​​cylindrical sleeve 119, and a guide inclined portion is formed between the first snap-fit ​​cylindrical sleeve 117 and the second snap-fit ​​cylindrical sleeve 119 through the outer side wall of the first snap-fit ​​frustum sleeve 118.

[0087] The guide slope is formed by the outer wall of the first snap-fit ​​frustum sleeve 118. During the process of inserting the conduit protection hose 7, the slope formed by the guide slope can be used to smoothly send the conduit protection hose 7 into the hose sleeve 114 and fit it onto the hose sleeve 114, which makes it easy to fit the conduit protection hose 7 onto the hose sleeve 114 during the assembly process.

[0088] like Figure 12As shown, preferably, the gas-liquid-electric external connection assembly 4 includes a connector fixing sleeve 401, a gas-liquid-electric connection component 402, a cable fixing sleeve 405, and a connector outer sleeve 406; the connector fixing sleeve 401 has a cylindrical structure, one end of the connector fixing sleeve 401 is provided with an external threaded connection part, and the other end of the connector fixing sleeve 401 is recessed inward to form a connector fixing part; multiple connector fixing sleeves are provided axially on the connector fixing sleeve 401, and the connector fixing sleeve is provided through the connector fixing sleeve 401 axially.

[0089] like Figure 13 As shown, preferably, the gas-liquid-electric connection component 402 includes a connector fixing plate 407, a plurality of gas-liquid delivery connectors 403, and a plurality of electrical delivery connectors 404. The plurality of gas-liquid delivery connectors 403 and the plurality of electrical delivery connectors 404 are respectively passed through and fixed to the connector fixing plate 407, and the connector fixing plate 407 is snapped and fixed inside the connector fixing part. The gas-liquid delivery connectors 403 and the electrical delivery connectors 404 are sleeved on the connector fixing sleeve 401, and the water pipe, the gas pipe, and the conductive cable are respectively passed through the connector fixing sleeve 401.

[0090] Its function is to fix the gas-liquid transmission connector 403, the electrical transmission connector 404, and transmission pipes such as water pipes, gas pipes, and conductive cables inside it. For example, when a connector corresponds to an electrical transmission connector 404, a part of the electrical transmission connector 404 will be inserted into it, and a part of the conductive cable connected to the electrical transmission connector 404 will also be inserted into it. In general, the transmission connectors and transmission pipes have a one-to-one correspondence.

[0091] The connector fixing plate 407 serves to fix multiple gas-liquid delivery connectors 403 and multiple electrical delivery connectors 404, and is fixed to the connector fixing sleeve 401 via the connector fixing part, forming the basic plug structure of this gas-liquid-electric external connection assembly. The connector fixing plate 407 is set on the connector fixing sleeve 401 through the inwardly recessed connector fixing part, and then, by covering the gas-liquid delivery connectors 403, electrical delivery connectors 404, and corresponding water pipes, gas pipes, and conductive cables, it connects with the outside through the two types of connectors, so as to transmit external liquids, gases, or electrical signals into this device.

[0092] The cable fixing sleeve 405 is part of the supporting outer shell. The cable fixing sleeve has a cylindrical structure. The two ends of the cable fixing sleeve 405 are respectively provided with an internal thread connection part and an external thread connection part. The cable fixing sleeve 405 is fixedly connected to the external thread connection part of the connector fixing sleeve 401 through the internal thread connection part. The water pipe, the gas pipe and the conductive cable are sequentially passed through the connector fixing sleeve 401 and the cable fixing sleeve 405. The connector outer sleeve 406 is fixedly sleeved on the outside of the connector fixing sleeve 401 and the cable fixing sleeve 405. The end of the connector fixing sleeve 401 with the connector fixing part and the gas-liquid-electric connection component 402 are located outside the connector outer sleeve 406.

[0093] During connection, one end of the connector fixing sleeve 401, along with the gas-liquid delivery connector 403 and electrical delivery connector 404 on the gas-liquid-electric connection component 402, connects to the external device. Compared with the prior art which requires water connectors, liquid connectors, and electrical connectors, the structure in this technical solution is simpler and more efficient: after multiple gas-liquid delivery connectors 403 and multiple electrical delivery connectors 404 are provided on the gas-liquid-electric connection component 402, the pipes and cables are gathered by the cable fixing sleeve 405, forming an integral structure with the connector fixing sleeve 401 and the connector outer sleeve 406. This simple structure integrates electrical signal, liquid, and gas connection functions.
