Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a multifunctional dental treatment instrument. Background Art

[0002] Root canal treatment is a dental treatment method for treating diseases such as pulp disease and periapical disease. Through professional instruments, the infected tissues, bacteria, etc. in the root canal are cleaned, the root canal is shaped, disinfected and sterilized, and finally the root canal is tightly filled, so as to control the infection, prevent the occurrence of periapical periodontitis or promote the healing of the original periapical lesions.

[0003] Currently, the devices used in dental root canal treatment mainly include: ① root canal reamer, used for gradually expanding the root canal; ② root canal measuring instrument, used for measuring the root canal length; ③ root canal irrigation instrument (desktop wired), used for root canal irrigation; ④ root canal oscillator, used for root canal irrigation oscillation; ⑤ root canal filling instrument, used for filling the root canal; ⑥ ultrasonic root canal irrigation instrument, used for root canal irrigation. However, its disadvantages are that the main body and the working head are separated, there is a pipeline of more than one meter for transporting the medicine water, the path is too long, it is not suitable for transporting corrosive medicine water, the mobile operation is inconvenient, the water outlet of the working tip can only be in the middle part, it cannot match the root canal irrigation needle, the water cannot come out at the working tip, and the water path needs to be transported from the desktop main body.

[0004] In the current dental root canal treatment technology, after each root canal reaming is completed by the dentist, the required sodium hypochlorite, normal saline, chlorhexidine and other medicine water need to be drawn from the bottle using our normal medical syringe (or electric irrigation instrument "desktop wired"), and the root canal irrigation needle is installed, and then it is used for irrigation in the patient's dental root canal. (The doctor mainly relies on his own feeling for the use force and the irrigation duration). Then, another ultrasonic vibration working tip is used to oscillate the root canal, so that the disinfectant water can play a role and better enter the dentinal tubules for disinfection. In order to remove the debris remaining in the reaming or the redundant dentin residue that cannot be washed away after oscillation, the doctor needs to pick up the irrigation syringe again for irrigation to make the irrigation and disinfection effect as clean as possible. The above operations are repeated as the root canal is gradually expanded.

[0005] In summary, the current dental root canal treatment equipment still has the following defects: ① Whether it is operated by a doctor or a nurse, when using a manual syringe, there is a possibility of cross-infection when the syringe draws back and returns the medicine to the medicine bottle or when loading and unloading the needle; ② During the process of rinsing pressure, the manual sensing and control are inconsistent, and it is very difficult to control the amount and speed of the disinfectant rinse; ③ After the disinfectant rinse, root canal oscillation is performed. During oscillation, the debris in the root canal will float. When the doctor puts down the oscillator and picks up the rinse needle again, the debris will settle to the bottom of the root tip, making it possible that the root canal rinse is not thorough; ④ As a clinical operator, one more extra movement during treatment means one more possibility of infection; one more movement means wasting a little more treatment time, so it may affect the treatment effect.

[0006] In order to solve the problems of the existing dental treatment equipment being complex in operation, inconvenient to control, and difficult to ensure the treatment effect, it is necessary to improve the structure of the dental treatment equipment to solve the current technical problems.

[0027] Embodiment 1

[0028] As Figure 1 shown, a multifunctional dental treatment instrument includes a housing 1. The housing 1 is in the shape of a pistol for easy holding. A control circuit board 2, a battery 3, a water supply assembly 4 and a vibration assembly 5 are embedded inside the housing 1. The water supply assembly 4 includes a water bottle 41 and a peristaltic pump 42. The water bottle 41 and the peristaltic pump 42 are embedded in the grip position of the housing 1. The vibration assembly 5 is an ultrasonic suspension motor 51, and the ultrasonic suspension motor 51 is embedded in the gun body position. The water bottle 41 is communicated with the water inlet end of the peristaltic pump 42. The water inlet end of the ultrasonic suspension motor 51 is communicated with the water outlet end of the peristaltic pump 42 through a pipeline. The water outlet end of the ultrasonic suspension motor 51 is communicated with the water inlet end of the flushing needle 6 through a pipeline. The flushing needle 6 is a conventional medical cleaning needle in the prior art and is detachably connected to the muzzle end of the housing 1. The control circuit board 2 and the battery 3 are embedded in the gun tail position. The control circuit board 2 is electrically connected to the battery 3, the peristaltic pump 42 and the ultrasonic suspension motor 51. The battery 3 provides power supply for the peristaltic pump 42 and the ultrasonic suspension motor 51. The control circuit board 2 controls the water supply amount of the peristaltic pump 42 and the vibration frequency of the ultrasonic suspension motor 51.

[0029] The working principle of this embodiment is outlined as follows:

[0030] The battery 3 powers the peristaltic pump 42. The peristaltic pump 42 extracts the disinfected water in the water bottle 41 and transports it through a pipeline to the ultrasonic suspension motor 51. The battery 3 powers the ultrasonic suspension motor 51. The hollow vibrating main rod of the ultrasonic suspension motor 51 transports the disinfected water to flush the needle 6 for cleaning. The working parameters of the peristaltic pump 42 and the ultrasonic suspension motor 51 are controlled by the control circuit board 2, so as to adjust the water supply volume, vibration wave force, etc., so as to realize synchronous vibration and flushing. Through the precise control of the control circuit board 2, both flushing and oscillation can work regularly and quantitatively, without redundant actions, achieving the concept of fastness.

[0031] Embodiment 2

[0032] As Figure 2 shown, a multifunctional dental treatment instrument, the difference from Embodiment 1 is that: the water supply assembly 4 includes a water bottle 41 and a peristaltic pump 42. The water bottle 41 and the peristaltic pump 42 are embedded in the handle position of the housing 1. The water inlet end of the flushing needle 6 is connected to the water outlet end of the peristaltic pump 42 through a metal water pipe, and the water bottle 41 is connected to the water inlet end of the peristaltic pump 42; the vibration assembly 5 is an eccentric motor 52 close to the flushing needle 6. The control circuit board 2 and the battery 3 are embedded in the gun tail position. The control circuit board 2 is electrically connected to the battery 3, the peristaltic pump 42 and the eccentric motor 52. The battery 3 provides power supply for the peristaltic pump 42 and the eccentric motor 52. The control circuit board 2 controls the water supply volume of the peristaltic pump 42 and the vibration frequency of the eccentric motor 52.

[0033] The working principle of this embodiment is summarized as follows:

[0034] The battery 3 powers the peristaltic pump 42. The peristaltic pump 42 extracts the disinfected water in the water bottle 41 and transports it through a metal pipeline to the flushing needle 6 for flushing. The eccentric motor 52 is fixed at a position close to the flushing needle 6. The battery 3 powers the eccentric motor 52. The eccentric motor 52 drives the needle to vibrate. The peristaltic pump 42 transports the disinfected water to the flushing needle 6. In this way, the flushing needle 6 can realize the function of synchronous flushing and rinsing. Through the precise control of the control circuit board 2, both flushing and oscillation can work regularly and quantitatively, without redundant actions, achieving the concept of fastness.

[0035] Embodiment 3

[0036] As Figure 3As shown in the figure, a multifunctional dental treatment instrument, which is different from that of Embodiment 1 in that: the water supply component 4 is embedded in the position of the gun body, including a booster water bottle 43, a water bottle moving chassis 44, a spiral push plate 45 and a speed reduction telescopic motor 46. The water outlet end of the booster water bottle 43 is connected to the water inlet end of the flushing needle 6 through a metal water pipe. The water bottle moving chassis 44 is movably embedded in the inner cavity of the booster water bottle 43. The spiral push plate 45 is movably connected to the output shaft of the speed reduction telescopic motor 46. Driven by the speed reduction telescopic motor 46, the spiral push plate 45 is adjustably pressed against the water bottle moving chassis 44; the vibration component 5 is an eccentric motor 52 close to the flushing needle 6. The control circuit board 2 and the battery 3 are embedded in the handle position. The control circuit board 2 is electrically connected to the battery 3, the speed reduction telescopic motor 46 and the eccentric motor 52. The battery 3 provides power supply for the speed reduction telescopic motor 46 and the eccentric motor 52. The control circuit board 2 controls the vibration frequency of the eccentric motor 52 and the rotation speed of the speed reduction telescopic motor 46 to adjust the water supply volume of the booster water bottle 43.

[0037] The working principle of this embodiment is outlined as follows:

[0038] The battery 3 supplies power to the speed reduction telescopic motor 46. After the speed reduction telescopic motor 46 extends forward and presses against the water bottle moving chassis 44 to generate a thrust, the booster water bottle 43 is like manual injection usually. The disinfectant water is pushed forward and conveyed through the metal water pipe to the cleaning needle for cleaning. The battery 3 supplies power to the eccentric motor 52, and the eccentric motor 52 drives the needle to vibrate. The speed reduction telescopic motor 46 extends forward to convey the disinfectant water to the flushing needle 6. In this way, the flushing needle 6 can realize the function of simultaneous flushing and rinsing. Through precise control of the control circuit board 2, both flushing and oscillation can work regularly and quantitatively, without redundant actions, achieving the concept of quickness.

[0039] Embodiment 4

[0040] As Figure 4As shown, a multifunctional dental treatment instrument, which is different from that of Embodiment 1 in that: the water supply assembly 4 includes a boosting water bottle 43, a water bottle moving chassis 44, a spiral push plate 45 and a speed reduction telescopic motor 46; the vibration assembly 5 is an ultrasonic suspension motor 51; the water outlet end of the boosting water bottle 43 is connected to the water inlet end of the ultrasonic suspension motor 51 through a pipeline; the water outlet end of the ultrasonic suspension motor 51 is connected to the water inlet end of the flushing needle 6 through a pipeline; the water bottle moving chassis 44 is movably embedded in the inner cavity of the boosting water bottle 43; the spiral push plate 45 is movably connected to the output shaft of the speed reduction telescopic motor 46; under the drive of the speed reduction telescopic motor 46, the spiral push plate 45 is adjustably pressed against the water bottle moving chassis 44. The control circuit board 2 and the battery 3 are embedded in the grip position. The control circuit board 2 is electrically connected to the battery 3, the speed reduction telescopic motor 46 and the ultrasonic suspension motor 51. The battery 3 provides power supply for the speed reduction telescopic motor 46 and the ultrasonic suspension motor 51. The control circuit board 2 controls the vibration frequency of the ultrasonic suspension motor 51 and the rotation speed of the speed reduction telescopic motor 46 to adjust the water supply volume of the boosting water bottle 43.

[0041] The working principle of this embodiment is outlined as follows:

[0042] The battery 3 supplies power to the speed reduction telescopic motor 46. After the speed reduction telescopic motor 46 extends forward and presses against the water bottle moving chassis 44 to generate a thrust, the boosting water bottle 43 is like a manual injection usually. The disinfectant water is pushed forward and conveyed to the ultrasonic suspension motor 51 through a pipeline. The battery 3 supplies power to the ultrasonic suspension motor 51. The hollow vibration main rod of the ultrasonic suspension motor 51 conveys the disinfectant water to the flushing needle 6 for cleaning. By controlling the rotation speed of the speed reduction telescopic motor 46 and the working parameters of the ultrasonic suspension motor 51 through the control circuit board 2, the water supply volume and the vibration wave force, etc. are adjusted, so as to realize the synchronous vibration and flushing. Through the precise control of the control circuit board 2, both the flushing and the oscillation can work regularly and quantitatively, without redundant actions, achieving the concept of quickness.

[0043] It should be noted that, as Figure 5 shown, the housing 1 in the above-mentioned several embodiments can also be designed as a cylindrical shape that is convenient to hold according to the use requirements, which can further reduce the overall structure size of the treatment instrument and is convenient for storage and placement.

[0044] In addition, as Figure 6 shown, in order to facilitate the replacement of the water bottle 42 or the boosting water bottle 43, a replacement window is also opened on the housing 1 of the above-mentioned several embodiments. When the disinfectant water in the water bottle 42 or the boosting water bottle 43 is consumed, it can be taken out from the replacement window for replacement, improving the replacement efficiency.

[0045] In summary, the multi-functional dental treatment instrument provided by the present invention realizes a uniform disinfection water bottle 41 with a capacity of one small bottle for each patient, thus preventing cross-infection. The water supply component 4 and the vibration component 5 are controlled by the control circuit board 2 to work simultaneously or independently, truly realizing an integrated machine for flushing, washing, rinsing, and cleaning. The operator does not need to manually extract the disinfection liquid from the disinfection water bottle 41 or repeatedly change tools, preventing the risk of precipitation of dentin debris and contact infection during operation, assisting the doctor to be unaffected by emotions and states, enabling quantitative and timed flushing to prevent the problem of insufficient cleaning time; being able to control the water volume to be fast or slow, with controllable drip-like, continuous drip-like, continuous water output, and rapid water output, which is difficult to solve by manual operation; having a timed flushing duration: such as 5 seconds, 8 seconds, 10 seconds, 12 seconds as a unit for the single-root flushing time; adjustable frequency, and the doctor can increase or decrease according to the work needs; the drug delivery path is short during operation, achieving the effect of immediate output when pressed.

[0046] In addition, the multi-functional dental treatment instrument provided by the present invention can also be used for periodontal pocket flushing.

[0047] Existing periodontal pocket flushing instruments and periodontal treatment instruments are desktop types that require plugging in the power supply (there is a possibility of power danger) and have a long pipeline transportation path, which is inconvenient to use. The flushing instrument can only perform normal flushing and cannot perform micro-oscillation, making it difficult to clean the soft scale in the periodontal pocket. The periodontal treatment instrument focuses on cleaning calculus hard masses, bacteria staining, etc. If it is used to flush the periodontal pocket every time, the teeth will be traumatically damaged because it works based on the ultrasonic principle for solidified bacteria, and the water outlet of the working tip is also in the middle part of the working tip, and the water cannot reach the tip and the side of the tail of the working tip. In addition, when manually flushing using a syringe and a root canal irrigation needle, it is extremely difficult for the operator to control the depth of the periodontal pocket while squeezing the syringe, either the cleaning depth is insufficient or the insertion is too deep, causing rebleeding, and it is also difficult to control the flushing water volume, and at the same time, it cannot provide micro-oscillation flushing.

[0048] When the multi-functional dental treatment instrument provided by the present invention is used in periodontal pocket cleaning, it can also set a stable water volume, improve the operator's concentration and control degree, and the periodontal depth. At the same time, the device can set a periodontal mode (micro-oscillation) according to needs to cooperate with the flushing, which is more beneficial to the cleaning and flushing of the soft scale and bacteria in the narrow gingival sulcus where the soft (gingiva) and hard (tooth) tissues of the periodontal pocket are in contact. Therefore, a better treatment effect can be achieved.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
