Description

Technical Field

[0001] The invention relates to an oral treatment endoscopic instrument, in particular to an endoscope used for periodontal subgingival treatment. Background Art

[0002] Periodontal disease, especially periodontitis, is the most common oral disease. If not treated in time, as the disease progresses, symptoms such as gum bleeding, periodontal pockets, abscesses, and loose teeth may appear. The main pathogenic factors of periodontitis are dental calculus and plaque attached to the surface of the tooth root.

[0003] Periodontal scaling is the most basic treatment for various periodontal diseases, and subgingival scaling and root planing are important steps. Especially for patients who have formed periodontal pockets, subgingival scaling is the main means to remove tartar and plaque on the root surface inside the periodontal pocket.

[0004] At present, the usual treatment process is to use a fine subgingival scaler to scrape around the root surface of the tooth based on the reflection of the dental mirror and the feel of the hand to remove the diseased tissue on the root surface and scattered tartar and plaque to make the root surface smooth. During or after the scaling operation, a sharp probe must be used to carefully check whether the subgingival tartar has been scraped away cleanly and whether the root surface is smooth to determine the effectiveness of the scaling.

[0005] Since the scraping is performed only by the reflection of the mouth mirror and the feel of the hand, it is impossible to observe the scraping situation in the periodontal pocket well, so it is very easy to cause tissue damage or unclean scraping. To avoid this situation, periodontal endoscopes are now used to assist the subgingival scraping process. The usual operation is to hold the periodontal endoscope in one hand, insert the lens into the periodontal pocket, and use the other hand to operate the subgingival scraper to scrape the root surface. Since the operation requires the cooperation of both hands, during the treatment process, it is very easy for the observation angle and movement trajectory of the periodontal endoscope to not match the treatment action of the subgingival scraper, which is very inconvenient for clinical use and prone to misoperation.

[0006] Therefore, the purpose of the present application is to design an improved endoscopic system for use in the subgingival scraping process, which can follow the movement of the subgingival scraper in real time and ensure that the working end of the scraper is continuously within the observation field of the endoscope, so as to improve the safety and convenience of clinical application. Summary of the invention

[0007] The subgingival treatment endoscope of the present invention combines the endoscope and the instrument as a whole, and adjusts the direction of the lens in three-dimensional space so that the field of view of the endoscope can follow the working movement of the instrument in real time, making clinical use more convenient and safer.

[0008] The subgingival treatment endoscope of the present invention is characterized in that: the subgingival treatment endoscope 100 comprises an observation system 1, a host 2, a display device 3 and a circuit system 4;

[0009] A. The observation system 1 comprises a lens module 11, a posture adjustment mechanism 12 and a fixed connection mechanism 13; the posture adjustment mechanism 12 adjusts the viewing angle and the visual field of the lens module 11; the lens module 11 and the posture adjustment mechanism 12 are mounted on the fixed connection mechanism 13; the fixed connection mechanism 13 connects and mounts the observation system 1 on the dental instrument 200;

[0010] B. The host 2 comprises a housing 21, a data collection and processing system 22 and a control system 23; the data collection and processing system 22 and the control system 23 are arranged in the housing 21 and / or on the housing 21;

[0011] C. The observation system 1 , the host 2 and the display device 3 are connected together via the circuit system 4 ; the data collected by the observation system 1 are analyzed and processed by the host 2 and then displayed on the display device 3 .

[0012] The subgingival treatment endoscope of the present invention is connected to the dental instrument 200 through the fixed connection mechanism 13 to form a whole. During clinical use, according to observation needs, the observation angle of the camera 11-1 of the lens module 11 can be spatially adjusted to ensure that the working end 200-1 of the dental instrument 200 is continuously within the field of view of the camera 11-1. The treatment process can be observed in real time, which is safer. Moreover, since the subgingival treatment endoscope 100 and the dental instrument 200 form a whole, it can be ensured that the subgingival treatment endoscope 100 can move with the dental instrument 200 in real time, and there is no movement mismatch, which is very convenient for clinical use.

[0013] The observation system 1 is provided with a water spray demisting device 14, which keeps the lens module 11 clear. The water spray demisting device 14 can spray water to clean the camera 11-1 of the lens module 11, so as to avoid fogging or blood stains on the surface of the camera 11-1, which may cause unclear observation.

[0014] The water spray demisting device 14 includes a water spray switch 14-1, and the water spray switch 14-1 controls the water spray demisting operation of the water spray demisting device 14. The water spray switch 14-1 can turn on and off the water spray demisting device 14. When in use, the water spray demisting device 14 is turned on as needed to flush the camera 11-1, and the water spray switch 14-1 also has an adjustment function, and the water volume and speed can be adjusted as needed to meet the flushing requirements.

[0015] The lens module 11 is provided with an anti-fog coating. The anti-fog coating may be a hydrophilic coating, which forms a water film on the surface of the camera 11-1 to prevent fogging. The anti-fog coating may also be a hydrophobic coating, so that the flushing liquid or blood forms water droplets on the camera 11-1 and does not adhere to the surface of the camera 11-1 to form water mist. The anti-fog coating may also be a mixed coating, which is a composite hydrophobic coating on the basis of a hydrophilic coating to achieve a better anti-fog effect.

[0016] The observation system 1 is provided with a vibration anti-fog mechanism 15, and the vibration anti-fog mechanism 15 removes the water mist on the lens module 11 by vibration. The vibration anti-fog mechanism 15 can remove the water mist on the lens module 11 by mechanical vibration or electromagnetic vibration. In particular, when an ultrasonic scaler is used for scraping, the ultrasonic vibration of the working end 200-1 of the dental instrument 200 can be transmitted to the lens module 11 through the fixed connection mechanism 13. The working end 200-1 and the fixed connection mechanism 13 together constitute the vibration anti-fog mechanism 15, thereby playing a vibration anti-fog effect on the camera 11-1.

[0017] The lens module 11 is detachably connected to the host 2, and the lens module 11 is disposable. The lens module 11 is detachably connected to the host 2 by an interface, so in clinical applications, the lens module 11 can be manufactured as a disposable consumable, thereby better ensuring the clinical safety of the lens module 11.

[0018] The lens module 11 includes a camera 11-1 and a light source 11-2. The lens module 11 is integrated with the light source 11-2, which can provide lighting for the camera 11-1. No additional light source is required during use, which is more convenient to use.

[0019] The light source 11-2 is an LED light source, and the light source 11-2 is arranged around the camera 11-1. The light source 11-2 is an LED light source, and since the LED light source has the advantage of low heat generation, the light source 11-2 can be directly arranged around the camera 11-1, and the lighting effect is better.

[0020] The wavelength of the light source 11-2 is adjusted to meet the needs of observation and treatment. The wavelength of the light source 11-2 can be adjusted to meet different usage requirements. For example, when dental plaque needs to be displayed, the wavelength of the light source 11-2 can be adjusted to ultraviolet light in the wavelength range of 300-500nm; when periodontal treatment is required, the wavelength of the light source 11-2 can be adjusted to a therapeutic light source with different wavelengths such as 600-800nm, 1000-1100nm, 2900-3000nm, etc.

[0021] The posture adjustment mechanism 12 is a multi-dimensional three-dimensional space position adjustment mechanism 12 - 1 . The posture adjustment mechanism 12 can achieve multi-dimensional space position adjustment of the lens module 11 , such as translation, lifting, axial rotation, radial rotation, etc.

[0022] The multi-dimensional stereoscopic space position adjustment mechanism 12-1 has at least a three-dimensional adjustment function. The multi-dimensional stereoscopic space position adjustment mechanism 12-1 includes at least three-dimensional adjustment functions of the camera module's front-back, left-right translation, and up-down lifting.

[0023] The multi-dimensional stereoscopic spatial position adjustment mechanism 12-1 has four-dimensional adjustment functions, including three-dimensional spatial adjustment and rotation adjustment. In addition to the adjustment functions of front-to-back, left-to-right, left-to-right, and up-and-down adjustment, the multi-dimensional stereoscopic spatial position adjustment mechanism 12-1 can also realize the rotation adjustment of the lens module 11 around the axial direction and around the radial direction.

[0024] The posture adjustment mechanism 12 adopts an electric adjustment method, and / or a manual adjustment method, and / or a shaping adjustment method. The posture adjustment mechanism 12 can adopt an electric adjustment method driven by a motor, or a manual adjustment method driven by manual translation, rotation, etc., or a combination of electric and manual methods to adjust and control the posture adjustment mechanism 12 to achieve the purpose of multi-dimensional three-dimensional space adjustment. The posture adjustment mechanism 12 can also use a shaping material or a shaping mechanism to adjust the direction, angle, etc. of the camera 11-1.

[0025] The manual adjustment method adopts a translation switch and / or a rotary switch. The manual adjustment method can be a manual adjustment method such as slide translation, thread rotation, concave-convex card matching, etc. The applicant only gives examples of the above-mentioned adjustment methods. Those skilled in the art can design other connection methods as needed. The applicant does not give examples one by one here, but they do not deviate from the protection scope of this application.

[0026] The fixed connection mechanism 13 is a detachable connection mechanism 13 - 1 or a non-detachable connection mechanism 13 - 2 .

[0027] The detachable connection mechanism 13-1 adopts a rotation connection method, and / or a convex-concave card fitting connection method, and / or an interference fit connection method. The applicant only gives examples of the above-mentioned detachable connection methods. The technicians in this field can design other connection methods as needed. The applicant does not give examples one by one here, but they all do not deviate from the protection scope of this application. The detachable connection mechanism 13-1 can realize the removal of the lens module 11 from the dental instrument 200, can meet the needs of different instruments, and can be cleaned, replaced, etc. when necessary. In particular, it can realize the disposable use of the lens module 11 at a low cost.

[0028] The fixed connection mechanism 13 includes a supporting mechanism 13 - 3 , one end of which is connected to the observation system 1 , and the other end of which is connected to the dental instrument 200 .

[0029] One end of the supporting mechanism 13 - 3 is connected to the observation system 1 , and the other end is connected to the working end 200 - 1 of the dental instrument 200 .

[0030] The ultrasonic vibration of the working end 200 - 1 is transmitted to the lens module 11 through the supporting mechanism 13 - 3 to remove the water mist on the lens module 11 .

[0031] The support mechanism 13-3 can not only effectively connect the subgingival treatment endoscope of the present invention to the dental instrument 200 to facilitate the real-time observation and recording of the working process of the dental instrument 200, but also, especially when the dental instrument 200 is an ultrasonically driven instrument, the support mechanism 13-3 can also transmit the ultrasonic vibration of the working end 200-1 of the dental instrument 200 to the lens module 11, so that the support mechanism 13-3 and the dental instrument 200 together constitute the vibration anti-fog mechanism 15 to play an anti-fog role. That is, the support mechanism 13-3 has both the functions of connection and fixation and vibration transmission.

[0032] The working end 200-1 is within the observation field of the lens module 11. The working end 200-1 is continuously kept within the observation field of the lens module 11, which can ensure continuous and effective real-time observation during clinical treatment.

[0033] The data collection and processing system 22 includes an artificial intelligence (AI) medical image processing unit, which performs AI intelligent analysis on the image data collected by the lens module 11, and outputs the analysis results to the display device 3, and / or prompts the operator. The artificial intelligence (AI) medical image processing unit can automatically perform AI intelligent analysis on the image data collected by the lens module 11 according to the algorithm, and the control system 23 takes measures according to the analysis results, such as outputting the results to the display device 3, issuing an alarm sound prompt, and providing an operation voice prompt to the operator.

[0034] The artificial intelligence (AI) medical image processing unit automatically identifies whether the working end 200-1 of the dental instrument 200 is within the observation field of the lens module 11. When the working end 200-1 is not within the observation field of the lens module 11, the artificial intelligence (AI) medical image processing unit sends a control instruction to the posture adjustment mechanism 12 through the circuit system 4, and automatically adjusts the spatial position of the lens module 11 to ensure that the working end 200-1 is continuously within the observation field of the lens module 11. This automatic adjustment method can realize the automatic deviation correction of the subgingival treatment endoscope of the present invention during use, ensure that the working end 200-1 is continuously within the observation field of the lens module 11, thereby ensuring continuous real-time observation during use, and the clinical use process is very safe and convenient.

[0035] The data analyzed and processed by the data collection and processing system 22 is transmitted to the display device 3 by wired or wireless means. The data analyzed and processed by the data collection and processing system 22 can be directly connected and transmitted to the display device 3 for display through a data cable, or can be transmitted to the display device 3 for display through a Wifi wireless connection or the like, or can be remotely transmitted to the display device 3 for display through a network.

The applicant only illustrates the above display modes, and those skilled in the art can select different display modes as needed, but they do not deviate from the protection scope of this application.

[0037] The fixed connection mechanism 13 is a non-detachable connection mechanism 13-2, and the non-detachable connection mechanism 13-2 is integrally manufactured on the dental instrument 200. The subgingival treatment endoscope of the present invention can also be integrally manufactured on the dental instrument 200, and during use, no additional connection is required, and clinical use is simpler, especially it can be made into a disposable whole with the working end 200-1, and the clinical use process is safer and more hygienic.

[0038] During clinical use, the subgingival treatment endoscope of the present invention is connected to the dental instrument 200, and the observation angle of the lens module 11 is adjusted according to the angle of the working end 200-1 to ensure that the working end 200-1 is within the observation field of the lens module 11. During use, since the lens module 11 and the working end 200-1 are in a stable connection state, the lens module 11 can move with the movement of the working end 200-1, thereby ensuring that the working end 200-1 is continuously within the observation field of the lens module 11, and the whole subgingival scraping process can be observed in real time, which can not only avoid accidental injuries caused by operating by feel, but also can intuitively judge whether the scraping is completely completed.

[0039] The subgingival treatment endoscope of the present invention comprises an observation system 1, a host 2, a display device 3 and a circuit system 4.

[0073] Example 1: Subgingival treatment endoscope of the present invention

[0074] refer to Figure 1 to Figure 1-2 : The subgingival treatment endoscope 100 includes an observation system 1, a host 2, a display device 3 and a circuit system 4.

[0075] The observation system 1 includes a lens module 11, a posture adjustment mechanism 12 and a fixed connection mechanism 13. The posture adjustment mechanism 12 adjusts the viewing angle and the visual field of the lens module 11. The lens module 11 and the posture adjustment mechanism 12 are mounted on the fixed connection mechanism 13. The fixed connection mechanism 13 connects and mounts the observation system 1 on the dental instrument 200.

[0076] The host 2 includes a housing 21 , a data collection and processing system 22 and a control system 23 ; the data collection and processing system 22 and the control system 23 are arranged in the housing 21 and / or on the housing 21 .

[0077] The observation system 1, the host 2 and the display device 3 are connected together via the circuit system 4. The data collected by the observation system 1 are analyzed and processed by the host 2 and then displayed on the display device 3.

[0078] The lens module 11 includes a camera 11-1 and a light source 11-2. The lens module 11 is integrated with the light source 11-2, which can provide lighting for the camera 11-1. No additional light source is required during use, which is more convenient to use.

[0079] The camera 11 - 1 can be a fixed-focus lens module with a large depth of field, or an auto-focus lens module to keep the field of view clear and meet different clinical needs.

[0080] refer to Figure 1-1 In this embodiment, the light source 11-2 is an LED light source, and the light source 11-2 is arranged around the camera 11-1. The light source 11-2 is an LED light source. Since the LED light source has the advantage of low heat generation, the light source 11-2 can be directly arranged around the camera 11-1, and the lighting effect is better.

[0081] In practical applications, the wavelength of the light source 11-2 can also be designed as a light source with adjustable wavelength to meet different usage requirements. For example, when it is necessary to display dental plaque, the wavelength of the light source 11-2 can be adjusted to ultraviolet light in the wavelength range of 300-500nm; when periodontal treatment is required, the wavelength of the light source 11-2 can be adjusted to therapeutic light sources with different wavelengths such as 600-800nm, 1000-1100nm, 2900-3000nm, etc.

[0082] In this embodiment, the posture adjustment mechanism 12 is a multi-dimensional three-dimensional spatial position adjustment mechanism 12-1 that adopts manual adjustment. The posture adjustment mechanism 12 can realize the spatial position adjustment of the lens module 11 in multiple dimensions such as translation, lifting, axial rotation, and radial rotation.

[0083] refer to Figure 1-1 and Figure 1-2Further, in this embodiment, the multi-dimensional three-dimensional spatial position adjustment mechanism 12-1 is composed of a sleeve 12-11 and a ball joint 12-12. The dental instrument 200 is an ultrasonic tooth cleaning machine 201, and the sleeve 12-11 is arranged at the front end of the handle 201-1 of the ultrasonic tooth cleaning machine 201, and can slide forward and backward along the axial direction of the slide groove 201-11 at the front end of the handle 201-1 to adjust the relative position of the camera 11-1 and the working end 200-1, so as to ensure that the working end 200-1 of the dental instrument 200 is within the field of view of the camera 11-1; the sleeve 12-11 can also rotate around the axial direction of the front end of the handle 201-1 to adjust the angle at which the camera 11-1 observes the working end 200-1. In addition, pushing the adjustment handle 12-12-1 of the ball joint 12-12 can also adjust the field of view and the observation angle of the camera 11-1 observing the working end 200-1. For example, by pressing the adjustment handle 12-12-1 backward, the camera 11-1 is lifted upward, and the field of view of the camera 11-1 is offset toward the distal end of the working part 200-1; by pushing the adjustment handle 12-12-1 forward, the camera 11-1 is pressed downward, and the field of view of the camera 11-1 is moved toward the distal end of the working part 200-1; by pushing the adjustment handle 12-12-1 to the right, the field of view of the camera 11-1 is offset toward the left side of the working part 200-1; by pushing the adjustment handle 12-12-1 to the left side, the field of view of the camera 11-1 is offset toward the right side of the working part 200-1. The multi-dimensional three-dimensional spatial position adjustment mechanism 12-1 can arbitrarily adjust the spatial position and angle of the observation system 1 in the three-dimensional space to ensure that the working field of view during subgingival scaling is continuously in a clear state.

[0084] The multi-dimensional three-dimensional space position adjustment mechanism 12-1 can also be formed by a combination of a concave-convex card fitting joint and a threaded connection. Figure 2-1 , Figure 2-2 , Figure 2-5 and Figure 2-6 The multi-dimensional three-dimensional spatial position adjustment mechanism 12-1 comprises a sleeve 12-11 and a rotating slot 12-17. The rotating slot 12-17 is composed of a motion slot 12-17-1 and a rotating column 12-17-2. A stopper 12-17-11 is provided in the motion slot 12-17-1. The rotating column 12-17-2 rotates in the motion slot 12-17-1 and is positioned by the stopper 12-17-11, so that the camera 11-1 can swing back and forth vertically and adjust the relative angle between the camera 11-1 and the working end 200-1.

[0085] refer to Figure 1-1In this embodiment, the fixed connection mechanism 13 is a non-detachable connection mechanism 13-2, and the non-detachable connection mechanism 13-2 is integrally manufactured on the dental instrument 200. The subgingival treatment endoscope of the present invention can also be integrally manufactured on the handle 201-1. During use, no additional connection is required, and clinical use is simpler. In particular, it can be made into a disposable whole with the handle 201-1, and the clinical use process is very hygienic.

[0086] The data collection and processing system 22 may also have a built-in artificial intelligence (AI) medical image processing unit, which performs AI intelligent analysis on the image data collected by the lens module 11, and outputs the analysis results to the display device 3, and / or prompts the operator. The artificial intelligence (AI) medical image processing unit can automatically perform AI intelligent analysis on the image data collected by the lens module 11 according to the algorithm, and the control system 23 takes measures according to the analysis results, such as outputting the results to the display device 3, issuing an alarm sound prompt, and providing an operation voice prompt to the operator.

[0087] The artificial intelligence (AI) medical image processing unit can also be set to an automatic closed-loop intelligent adjustment mode. The artificial intelligence (AI) medical image processing unit automatically identifies whether the working end 200-1 of the dental instrument 200 is within the observation field of the lens module 11. When the working end 200-1 is not within the observation field of the lens module 11, the artificial intelligence (AI) medical image processing unit sends a control instruction to the posture adjustment mechanism 12 through the circuit system 4 to automatically adjust the spatial position of the lens module 11 to ensure that the working end 200-1 is continuously within the observation field of the lens module 11. This automatic adjustment method can realize the automatic deviation correction of the subgingival treatment endoscope of the present invention during use, ensure that the working end 200-1 is continuously within the observation field of the lens module 11, thereby ensuring continuous real-time observation during use, and the clinical use process is very safe and convenient.

[0088] refer to Figure 3-5 The host 2 and the display 3 can be designed as an integrated machine 2-3, and the data collected by the camera module 11 is transmitted to the host 2, and is displayed on the display 33 after being analyzed and processed by the data collection and processing system 22. The integrated machine 2-3 can be directly set on the dental chair.

[0089] refer to Figure 7In practical applications, the data analyzed and processed by the data collection and processing system 22 can also be transmitted to the display device 3 for display via Wifi wireless connection or the like, or can be remotely transmitted to the display device 3 for display via a network. The applicant does not give examples one by one here, but they all fall within the scope of protection of this application.

[0090] refer to Figure 7 In addition to the display 33 in this embodiment, the display device 3 may also be a mobile phone 31, a tablet computer 32, a television 34 or a computer 35. The applicant only illustrates the above-mentioned display modes, and those skilled in the art may select different display modes as needed, but they do not depart from the protection scope of this application.

[0091] refer to Figure 4 During clinical use, the distance and field of view angle of the lens module 11 are adjusted according to the position of the working end 200-1 to ensure that the working end 200-1 is within the observation field of the camera 11-1. During use, since the lens module 11 and the working end 200-1 are in a stable connection state, the lens module 11 can move with the movement of the working end 200-1, thereby ensuring that the working end 200-1 is continuously within the observation field of the lens module 11, and the whole subgingival scaling process can be observed in real time, which can not only avoid accidental injuries caused by operating by feel, but also intuitively judge whether the scaling is completely completed.

[0092] In this embodiment, since the observation system 1 and the handle 201-1 are manufactured as a whole, the observation angle, distance and range of the camera 11-1 can be spatially adjusted as needed through the multi-dimensional three-dimensional spatial position adjustment mechanism 12-1. During the subgingival cleaning process, it can be ensured that the working end 200-1 is continuously in the observation field of the lens module 11, and real-time observation of the entire subgingival scraping process can be achieved. It can not only avoid accidental injuries that may be caused by operating by feel, but also can intuitively judge whether the scraping is completely completed. It is very safe and convenient for clinical use.

[0093] Example 2: Subgingival treatment endoscope with defogging function of the present invention

[0094] refer to Figure 2 to Figure 2-6 The difference between this embodiment and Example 1 is that in this embodiment, the observation system 1 is provided with a defogger.

[0095] refer to Figure 2 to Figure 2-3 The demisting device is a water spray demisting device 14. The water spray demisting device 14 keeps the lens module 11 imaging clear.

[0096] refer to Figure 2-1 and Figure 2-5 In this embodiment, the observation system 1 includes a housing 16, and an anti-fog coating is provided on the observation window 16-1 of the housing 16, and an anti-fog coating is provided on the lens module 11. The anti-fog coating can be a hydrophilic coating, which forms a water film on the surface of the camera 11-1 to prevent fogging. The anti-fog coating can also be a hydrophobic coating, so that the flushing liquid or blood forms water droplets on the camera 11-1 and will not adhere to the surface of the camera 11-1 to form water mist. The anti-fog coating can also be a mixed coating, which is a composite hydrophobic coating on the basis of the hydrophilic coating to achieve a better anti-fog effect.

[0097] The front end of the housing 16 is provided with a water spray anti-fog device 14, and the water spray defogging device 14 includes a water spray switch 14-1 and a water spray port 14-2. The water spray port 14-2 is arranged near the observation window 16-1 and can be arranged at the rear end of the observation window 16-1 to spray water forward for flushing. Figure 2 and Figure 2-1 , it can also be arranged to spray water backwards at the front end of the observation window 16-1, refer to Figure 2-3 The water spray switch 14-1 controls the water spray demisting operation of the water spray demisting device 14. When the water spray switch 14-1 is pressed, the water flow ejected from the water spray port 14-2 can wash away the dirt attached to the observation window 16-1, clean the observation system 1, and keep the image clear. To facilitate the doctor's operation, the water spray switch 14-1 can be set on the handle 201-1 or set as a foot switch.

[0098] The water supply pipe of the water spraying and demisting device 14 can be built in the dental instrument 200 or designed to be external. The water supply pipe can be connected to the water pipe of the main unit 2 or the water pipe of the dental chair.

[0099] refer to Figure 2-4 to Figure 2-6 The demisting device may also use vibration to perform demisting to keep the imaging of the observation system 1 clear.

[0100] The observation system 1 is provided with a vibration anti-fog mechanism 15, and the vibration anti-fog mechanism 15 removes the water mist on the lens module 11 by vibration. The vibration anti-fog mechanism 15 can remove the water mist on the lens module 11 by mechanical vibration or electromagnetic vibration. In this embodiment, the vibration anti-fog mechanism 5 removes the water mist on the observation window 16-1 by ultrasonic vibration. Because the frequency of ultrasonic vibration is high and the amplitude is small, it can keep the image clear while removing the dirt attached to the lens of the observation system 1. The dental instrument 200 is an ultrasonic dental cleaning machine 201, and the fixed connection mechanism 13 includes a support mechanism 13-3, one end of the support mechanism 13-3 is connected to the observation system 1, and the other end is connected to the working end 200-1. The ultrasonic vibration of the working end 200-1 can be transmitted to the lens module 11 through the support mechanism 13-3, and the working end 200-1 and the support mechanism 13-3 together constitute the vibration anti-fog mechanism 15, thereby playing a vibration anti-fogging role on the camera 11-1. That is, the supporting mechanism 13 - 3 has the functions of connection and fixation and vibration transmission at the same time.

[0101] In this embodiment, the subgingival treatment endoscope 100 is provided with the anti-fog device, which can ensure that the field of view of the camera 11-1 remains clear during use, and the clinical use process is safer.

[0102] Example 3: Disposable subgingival treatment endoscope of the present invention

[0103] refer to Figure 3 to Figure 3-5 The difference between this embodiment and embodiment 1 is that, in this embodiment, the fixed connection mechanism 13 is a detachable connection mechanism 13-1, so that the front end of the subgingival treatment endoscope 100 can be disassembled and replaced to achieve disposable use, thereby better preventing medical-induced infection.

[0104] refer to Figures 3 to 3-5 In this embodiment, the detachable connecting mechanism 13-1 is detachably mounted on the handle 201-1 by combining interference fit and concave-convex fit.

[0105] refer to Figure 3-1 and Figure 3-2 The posture adjustment mechanism 12 is a multi-dimensional three-dimensional spatial position adjustment mechanism 12-1, which is composed of a sleeve 12-11 and a ball joint 12-12. The ball joint 12-12 includes a ball joint head 12-12-2 and a ball joint cavity 12-12-3. The ball joint head 12-12-2 is detachably installed in the ball joint cavity 12-12-3 by combining interference fit and concave-convex card fit. The ball joint head 12-12-2 and the ball joint cavity 12-12-3 together constitute the detachable connection mechanism 13-1.

[0106] The dental instrument 200 is an ultrasonic tooth cleaner 201, and the sleeve 12-11 is arranged at the front end of the handle 201-1 of the ultrasonic tooth cleaner 201, and can slide forward and backward along the axial direction of the front end of the handle 201-1 to adjust the relative position of the camera 11-1 and the working end 200-1, so as to ensure that the working end 200-1 of the dental instrument 200 is in the field of view of the camera 11-1; the sleeve 12-11 can also rotate around the axial direction of the front end of the handle 201-1 to adjust the angle at which the camera 11-1 observes the working end 200-1. In addition, pushing the adjustment handle 12-12-1 of the ball joint 12-12 can also adjust the field of view and the observation angle of the camera 11-1 observing the working end 200-1. The multi-dimensional three-dimensional space position adjustment mechanism 12-1 can arbitrarily adjust the spatial position and angle of the observation system 1 in the three-dimensional space to ensure that the working field of view during subgingival scaling is continuously in a clear state.

[0107] Before use, the observation system 1 is detachably mounted on the handle 201-1 through the ball joint 12-12. During clinical use, the distance and field of view angle of the lens module 11 are adjusted according to the position of the working end 200-1 to ensure that the working end 200-1 is within the observation field of the camera 11-1. If the camera 11-1 needs to be replaced during use or after use, the ball joint head 12-12-2 can be pulled out from the ball joint cavity 12-12-3, and the lens module 11 can be removed from the handle 201-1.

[0108] refer to Figure 5 and Figure 5-1The multi-dimensional three-dimensional spatial position adjustment mechanism 12-1 is composed of an adjustment slot 12-13 and a sleeve 12-11. The outer surface of the housing 16 is provided with a multi-faceted segment 16-2, which is embedded in the adjustment slot 12-13 by interference fit. The multi-faceted segment 16-2 can increase the friction force to ensure the stability of the connection with the inner surface of the adjustment slot 12-13, and can also achieve the function of grade division, with one facet representing one gear. The housing 16 is also provided with an adjustment handle 12-12-1. Rotating the adjustment handle 12-12-1 drives the multi-faceted segment 16-2 to rotate in the adjustment slot 12-13, thereby adjusting the angle between the camera 11-1 and the working end 200-1. The sleeve 12-11 is arranged at the front end of the handle 201-1. The handle 201-1 is provided with an external thread 201-12, which together with the sleeve 12-11 constitutes the detachable connection mechanism 13-2. The relative position between the camera 11-1 and the working end 200-1 can be adjusted by rotating the sleeve 12-11. In order to ensure that the sleeve 12-11 can be firmly installed at the front end of the handle 201-1, a protective cover 13-4 can be provided at the connection part. Figure 5-2 to Figure 5-4 Since the observation system 1 is connected to the dental instrument 200 by means of interference fit, the observation system 1 can be easily removed from the adjustment slots 12-13 during use, and removal and replacement are very convenient.

[0109] The multi-dimensional three-dimensional space position adjustment mechanism 12-1 can also realize arbitrary adjustment in all directions and angles through flexible design of the front end of the observation system 1, such as plastic material manufacturing, serpentine tube design, etc. Figure 5-5 A shaping mechanism 16 - 4 is designed at the front end of the housing 16 , and the camera 11 - 1 can be driven to adjust the spatial angle and position by adjusting the shaping mechanism 16 - 4 .

[0110] The observation system 1 is detachably connected to the host 2 through the circuit system 4, and the collected image data is displayed on the display device 3. In this embodiment, the detachable connection mode allows the observation system 1 of the subgingival treatment endoscope 100 to be made into a disposable medical consumable, which better prevents nosocomial infection and makes the clinical use process safer.

[0113] refer to Figure 6 and Figure 6-1 The multi-dimensional three-dimensional space position adjustment mechanism 12-1 is composed of a sleeve 12-11 and a gear transmission sleeve 12-15. The housing 16 of the observation system 1 is provided with a thread 16-3. The sleeve 12-11 and the gear transmission sleeve 12-15 are driven by a motor 12-16. Figure 6-2 The handle 201-1 is provided with a driving control switch 12-14, which includes a translation control switch 12-14-1 and a rotation control switch 12-14-2. The driving control switch 12-14 can control the observation system 1 to reciprocate along the axial direction of the handle 201-1 and to rotate around the axial direction to adjust the observation angle and field of view of the camera 11-1.
