Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a dental endoscope for clinical use in dentistry. Background Technology

[0002] As an important medical discipline, stomatology covers a wide range of diseases, such as oral and maxillofacial dermoids, epidermal submandibular space infections, maxillofacial lymphangiomas, odontoid process malformations, maxillary sinus malignancies, ameloblastoma of the jawbone, chronic ethmoid sinusitis, mandibular retrusion, tetracycline staining, and leukoplakia of the tongue. Under current medical technology, many periodontal diseases are curable. However, before treatment, a detailed observation of the oral cavity using a dental endoscope is a crucial step in accurately determining the condition.

[0003] Traditional dental mirrors are mostly simple structures consisting of a curved metal rod and an observation mirror. They require additional lighting to achieve clear observation and rapid diagnosis. To optimize the function of dental mirrors, innovative designs are constantly emerging. For example, the novel dental mirror for clinical use disclosed in Chinese Patent No. CN216754418U improves lighting, adjusts the angle and length of use, and provides a limiting function to prevent parts from detaching by incorporating adjustment devices within the main body and supporting pillars, fixing blocks, connecting pillars, connecting seats, and reflectors in relevant parts. This also provides greater convenience for oral examinations.

[0004] However, a closer look at practical applications reveals significant shortcomings in current oral endoscopy technology. Due to the substantial temperature difference between the endoscope and the oral cavity, the endoscope fogs up easily after insertion, making it difficult for doctors to clearly observe the internal conditions of the mouth. The commonly used method of heating the endoscope with an alcohol lamp to prevent fogging has several drawbacks. Firstly, heating with an alcohol lamp can easily cause the endoscope surface to become dirty, affecting the clarity of observation. Secondly, excessive heating may damage the endoscope, and if the endoscope surface temperature is too high, there is a risk of burning the patient's oral cavity when it is inserted. Furthermore, once the endoscope comes into contact with the oral cavity wall during insertion, saliva, mucous membranes, and other substances in the mouth adhere to it, obscuring the endoscope and severely affecting the overall observation effect, thus negatively impacting the accuracy and efficiency of diagnosis. Therefore, there is an urgent need to improve the design of oral endoscopes to overcome the deficiencies of existing technology. Summary of the Invention

[0005] In view of the lack of cleaning and anti-fogging functions in existing technologies, the purpose of this invention is to provide a dental mirror for clinical use in dentistry.

[0021] The cleaning mechanism further includes a weighted ball; the weighted ball is installed on the cleaning scraper at the end away from the sleeve.

[0022] Optionally, the cleaning scraper is arc-shaped, and the plurality of cleaning scrapers form a concentric arc in the initial state of rotation.

[0023] Optionally, a lamp holder is fixedly connected to the outer side of the housing, and a lighting lamp is fixedly connected to the lamp holder.

[0031] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0032] The oral endoscope for clinical use in stomatology provided by this invention, through the coordinated action of the drive mechanism, transmission mechanism and linkage mechanism, drives the cleaning mechanism to perform a circumferential cleaning on the mirror surface of the oral endoscope body. It can effectively remove fog, saliva and mucous membranes and other deposits on the mirror surface, ensuring a clear mirror surface, providing a good field of view for oral examination, without affecting the overall observation effect, and improving the accuracy and efficiency of disease diagnosis.

[0033] During use, the driving force of the drive mechanism is transmitted through the gear assembly, enabling the cleaning scraper to rotate. When the drive mechanism rotates in the reverse direction, the cleaning scraper overcomes the resistance of the torsion spring to powerfully clean the endoscope; when rotating in the forward direction, the torsion spring resets, causing the cleaning scraper to retract, thus preventing the endoscope from being obstructed. This achieves efficient cleaning without affecting the observation effect, providing reliable and efficient technical support for dental diagnosis.

[0034] The oral endoscope of this invention features automatic cleaning and flexible multi-angle adjustment. During use, the battery inside the casing provides stable power to the device, ensuring portability in different environments. When the reflection angle needs to be adjusted, the first motor is activated to rotate the housing, precisely changing the angle to meet the needs of different examination sites. This design allows doctors to flexibly observe various parts of the oral cavity, improving examination efficiency and accuracy. It plays a key role in oral examinations, providing strong support for diagnostic work and meeting diverse clinical observation needs.

[0035] By incorporating a support mechanism, the flexibility and convenience of using the oral endoscope are effectively enhanced. During use, activating the second motor allows its precise power to drive the lead screw to rotate stably within the rail frame. The sliding rod, due to its threaded engagement with the lead screw and its sliding within the rail frame, causes the rail frame and the oral endoscope device on top to move up and down. This design allows for flexible adjustment of the oral endoscope length according to actual needs, easily adapting to the operating habits of different patients and medical staff. Medical staff can conveniently operate the first and second motors and the lighting by adjusting the control switch. Turning on the lighting, combined with the mirror's reflection, facilitates the doctor's observation of the oral cavity; activating the first motor allows for precise adjustment of the housing angle, optimizing the clinical operating experience.

[0063] like Figures 1 to 9 As shown, this embodiment of the invention provides a dental endoscope for clinical use in dentistry. The endoscope includes: a support mechanism 1, an endoscope device 3, and an endoscope body 38; a housing 2 is fixedly mounted on the top of the support mechanism 1; the endoscope device 3 includes: a concave seat 32, a housing 33, a drive mechanism 34, a transmission mechanism 35, a linkage mechanism 36, and multiple cleaning mechanisms 37; the concave seat 32 is fixedly mounted on the top of the housing 2, and the housing 33 has a hollow cavity and is rotatably connected to the concave area of ​​the concave seat 32; the drive mechanism 34 is fixedly mounted on the concave seat 32. The dental endoscope body 38 is fixedly installed in the hollow cavity; the linkage mechanism 36 has a ring structure and is movably installed in the hollow cavity near the mirror surface of the dental endoscope body 38; multiple cleaning mechanisms 37 are arranged in a ring on the linkage mechanism 36; the linkage mechanism 36 is connected to the drive mechanism 34 through the transmission mechanism 35, and the drive mechanism 34 transmits driving force to the linkage mechanism 36 through the transmission mechanism 35, so as to drive the linkage mechanism 36 to drive the cleaning mechanism 37 to rotate around the central axis of the housing 33, thereby cleaning the mirror surface of the dental endoscope body 38 in a circumferential manner.

[0064] During operation, the dental endoscope used in this dental clinic is powered by a battery housed inside the casing 2. When the mirror surface of the endoscope body 38 needs cleaning, the drive mechanism 34, fixedly mounted on the concave base 32, is activated. The driving force generated by the drive mechanism 34 is transmitted to the linkage mechanism 36 through the transmission mechanism 35. The linkage mechanism 36 has a ring-shaped structure and is movably mounted in the hollow cavity of the housing 33 near the mirror surface of the endoscope body 38. After receiving the power from the transmission mechanism 35, the linkage mechanism 36 begins to rotate around the central axis of the housing 33. Since multiple cleaning mechanisms 37 are arranged in a ring on the linkage mechanism 36, the rotation of the linkage mechanism 36 will drive the cleaning mechanisms 37 to rotate synchronously around the central axis of the housing 33, thereby performing a circumferential cleaning of the mirror surface of the endoscope body 38, effectively removing fog, saliva, mucous membranes, and other deposits from the mirror surface, ensuring a clear mirror surface and providing a good field of vision for oral examinations.

[0065] like Figures 6 to 9 As shown, the drive mechanism 34 includes a base ring 341 and a first motor 342; the transmission mechanism 35 includes a gear assembly, an arc-shaped rack 343, and an internal gear ring 364; the first motor 342 is fixedly connected to one side of the concave seat 32, and the base ring 341 is rotatably connected to one side of the concave seat 32. The output end of the first motor 342 is connected to the base ring 341 to drive the base ring 341 to rotate; the arc-shaped rack 343 is fixedly connected to the inner wall of the inner ring of the base ring 341; the internal gear ring 364 is fixedly connected to the inner wall of the inner ring of the linkage mechanism 36. The arc-shaped rack 343 and the internal gear ring 364 are respectively meshed with the gear assembly. Under the rotation of the base ring 341, the arc-shaped rack 343 drives the internal gear ring 364 to move through the transmission of the gear assembly, so as to drive the linkage mechanism 36 to rotate.

[0066] When this oral endoscope is in operation, the first motor 342, fixed to one side of the concave base 32, is activated. The first motor 342 outputs power to drive the base ring 341 connected to it to rotate. During the rotation of the base ring 341, the arc-shaped rack 343 fixed on the inner wall of its inner ring moves accordingly. The arc-shaped rack 343 meshes with the gear assembly, transmitting the motion to the gear assembly, causing the gear assembly to rotate. The gear assembly then meshes with the internal gear ring 364 fixed on the inner wall of the inner ring of the linkage mechanism 36. Through the transmission of the gear assembly, the internal gear ring 364 is driven to move. Since the internal gear ring 364 is connected to the linkage mechanism 36, the movement of the internal gear ring 364 drives the linkage mechanism 36 to rotate around the central axis of the housing 33. The multiple cleaning mechanisms 37 arranged in a ring on the linkage mechanism 36 rotate synchronously, thereby realizing the circumferential cleaning of the mirror surface of the oral endoscope body 38, removing various deposits on the mirror surface, ensuring the mirror surface is clear, and providing convenience for oral examination.

[0067] Specifically, in some embodiments, the gear assembly may include: a driven spur gear 353, a driving spur gear 526, a driven bevel gear 523, a driving bevel gear 525, a rotating shaft 521, a connecting shaft 524, and a mounting base 522; the front end of the rotating shaft 521 is connected to the driven spur gear 353, the rear end of the rotating shaft 521 is connected to the driven bevel gear 523, the mounting base 522 is disposed on the housing 33, and the connecting shaft 524 is rotatably connected to the mounting base 522; the driving bevel gear 525 is fixedly connected to one end of the connecting shaft 524, the driving spur gear 526 is fixedly connected to the other end of the connecting shaft 524, the driving spur gear 526 is meshed with the inner side of the arc-shaped rack 343, and the driving bevel gear 525 is meshed with the driven bevel gear 523.

[0068] When the first motor 342 in the drive mechanism 34 drives the base ring 341 to rotate, the arc-shaped rack 343 fixed to the inner side wall of the inner ring of the base ring 341 moves accordingly. The arc-shaped rack 343 meshes with the inner side of the driving spur gear 526, driving the driving spur gear 526 to rotate. The driving spur gear 526 drives the driving bevel gear 525 at one end to rotate synchronously through the connecting shaft 524. Since the driving bevel gear 525 meshes with the driven bevel gear 523, the rotation of the driving bevel gear 525 is transmitted to the driven bevel gear 523. The bevel gear 523 drives the connected rotating shaft 521 to rotate. The driven spur gear 353 connected to the front end of the rotating shaft 521 rotates under the drive of the rotating shaft 521. The driven spur gear 353 meshes with the internal gear ring 364 fixed on the inner side wall of the inner ring of the linkage mechanism 36, and transmits power to the internal gear ring 364, driving the linkage mechanism 36 to rotate around the central axis of the housing 33, and finally realizes the circumferential cleaning of the surface of the oral endoscope 38 by the cleaning mechanism 37 installed on the linkage mechanism 36.

[0069] like Figures 8 to 9 As shown, in some embodiments, the transmission mechanism 35 may further include: a rear cover 351; the rear cover 351 is mounted on the housing 33 on the non-mirror side of the oral endoscope body 38, and the mounting base 522 is mounted on the rear cover 351. The rear cover 351 can be mounted to the back of the housing by screws, and the rear cover 351 is used to cover and protect the oral endoscope body 38, which is located on the front of the rear cover 351.

[0070] Furthermore, in some embodiments, the linkage mechanism 36 may include: an annular inner rail 361, a slip ring 362, and a connecting ring 363. The annular inner rail 361 is fixedly disposed on the inner sidewall of the housing 33, and the internal gear ring 364 is mounted on the annular inner rail 361, driving the annular inner rail 361 to rotate through the meshing transmission of the driven spur gear 353; the cleaning mechanism 37 is mounted on the connecting ring 363, and the connecting ring 363 is slidably connected to the annular inner rail 361 through the slip ring 362, so as to drive the cleaning mechanism 37 to rotate.

[0071] When the drive mechanism 34 is activated, it drives the base ring 341 to rotate. The arc-shaped rack 343, fixed to the inner wall of the inner ring of the base ring 341, moves accordingly. The arc-shaped rack 343 meshes with the inner side of the driving spur gear 526, causing the driving spur gear 526 to rotate around the connecting shaft 524. The connecting shaft 524 drives the driving bevel gear 525 at the other end to rotate synchronously. Since the driving bevel gear 525 meshes with the driven bevel gear 523, the rotation of the driving bevel gear 525 drives the driven bevel gear 523 to rotate, which in turn drives the rotating shaft 521 fixedly connected to it to rotate. The driven spur gear 353 at the front end of the rotating shaft 521 rotates on the shaft. Driven by 521, it rotates and meshes with the internal gear ring 364 installed on the annular inner rail 361, transmitting power to the internal gear ring 364, thereby driving the annular inner rail 361 to rotate around the central axis of the housing 33. The connecting ring 363 is slidably connected to the annular inner rail 361 through the slip ring 362. When the annular inner rail 361 rotates, the sliding engagement of the slip ring 362 drives the connecting ring 363 to rotate. Since the cleaning mechanism 37 is installed on the connecting ring 363, the rotation of the connecting ring 363 ultimately enables the cleaning mechanism 37 to rotate around the central axis of the housing 33, completing the circumferential cleaning of the mirror surface of the oral endoscope 38.

[0072] Further, in some embodiments, the cleaning mechanism 37 may include: a fixing ring 371, a sleeve 372, a torsion spring 373, a turntable 374, a connecting arm 375, and a cleaning scraper 376; the fixing ring 371 is arranged in a ring on the connecting ring 363, and the sleeve 372 is installed on the inner side wall of the fixing ring 371; one end of the torsion spring 373 is fixedly connected to the inside of the sleeve 372, and the other end is connected to the turntable 374; one end of the connecting arm 375 is fixedly connected to the turntable 374, and the other end is equipped with the cleaning scraper 376; the cleaning scraper 376 is in close contact with the mirror surface of the oral endoscope body 38, the connecting arm 375 is fixedly connected to one side of the turntable 374, the cleaning scraper 376 is fixedly installed at the rear end of the connecting arm 375, and the back side of the cleaning scraper 376 is in close contact with the front side of the oral endoscope body 38.

[0073] The cleaning mechanism 37 may also include a weighted ball 377; the weighted ball 377 is mounted on the cleaning scraper 376 at one end away from the sleeve 372.

[0074] In this embodiment, the cleaning scraper 376 can be designed in an arc shape, and multiple cleaning scrapers 376 form a concentric arc in the initial state of rotation.

[0075] In some embodiments, lamp holders 39 are fixedly connected at equal intervals on the outer side of the housing 33, and lighting lamps 310 are fixedly connected inside the lamp holders 39. The lighting lamps 310 are electrically connected to the battery inside the housing 2 through wires. Hollow wire tube sleeves 31 are fixedly connected to the top of the housing 2, and concave seats 32 are fixedly installed on the top of the hollow wire tube sleeves 31.

[0076] When using this dental clinical endoscope, the battery inside the housing 2 powers the lamp 310 in the lamp holder 39 via wires. After the user turns on the power, the lamp 310 lights up, illuminating the oral cavity environment and providing sufficient light for oral examination. At the same time, the drive mechanism 34 fixed on one side of the concave base 32 is activated. The power generated by the drive mechanism 34 is transmitted through the transmission mechanism 35 located on the back of the housing 33 to the linkage mechanism 36 movably installed inside the housing 33. After receiving the power, the linkage mechanism 36 starts to operate. Since the cleaning mechanism 37 is installed on the front of the linkage mechanism 36, the rotation of the linkage mechanism 36 drives the cleaning mechanism 37 to clean the endoscope body 38 fixed on the front of the transmission mechanism 35. The housing 33, which is rotatably connected inside the concave base 32, can flexibly adjust the angle during the examination. Together with the lamp 310 and the cleaning mechanism 37, it ensures that the endoscope body 38 maintains a clear field of vision at all times, providing doctors with good observation conditions and helping to complete oral examinations efficiently.

[0077] In some embodiments, the supporting mechanism 1 may include: a base plate 11, a frame 12, a rail frame 13, a lead screw 14, a slide bar 15, and a second motor 16; the frame 12 is mounted on the top of the base plate 11, and the rail frame 13 is mounted on the top of the frame 12; the rail frame 13 has a movable through hole, and the lead screw 14 is rotatably connected to the movable through hole; one end of the slide bar 15 is slidably sleeved on the outer surface of the lead screw 14, and the other end is fixedly connected to the bottom of the concave seat 32; the frame 12 has an inner cavity, and the second motor 16 is mounted in the inner cavity, and the output end of the second motor 16 extends through the frame 12 into the movable through hole and is connected to the end of the lead screw 14 to drive the lead screw 14 to rotate.

[0078] In some embodiments, the support mechanism 1 may further include: an operating armrest 17, an anti-slip armrest glove, and a control switch 18; the operating armrest 17 is installed at the bottom of the base plate 11, and the anti-slip armrest glove is fitted onto the outer surface of the operating armrest 17; the control switch 18 is installed on one side of the operating armrest 17, and the control switch 18 is electrically connected to the first motor 342 and the second motor 16 respectively to control the opening and closing of the first motor 342 and the second motor 16, and the control switch 18 is provided with a button 19.

[0079] In this embodiment, there can be three buttons 19, which control the first motor 342, the second motor 16 and the lighting lamp 310 respectively. The internal cavity of the rail frame 13 and the cross-sectional shape of the slide rod 15 can both be designed as regular hexagonal shapes.

[0080] When the dental endoscope is in operation, the button 19 on the control switch 18 on one side of the operating armrest 17 is operated to start the second motor 16. Its output end drives the lead screw 14 to rotate in the movable through hole of the rail frame 13. Since the internal cavity of the rail frame 13 and the cross section of the slide rod 15 are regular hexagonal, one end of the slide rod 15 is sleeved on the lead screw 14, and the other end is connected to the bottom of the concave seat 32. When the lead screw 14 rotates, the slide rod 15 can only slide in a straight line along the lead screw 14, thereby driving the concave seat 32 and the entire dental endoscope device 3 to move up and down to achieve height adjustment.

[0081] When the oral endoscope body 38 needs cleaning, press the corresponding button 19 on the control switch 18 to start the first motor 342. The first motor 342 drives the base ring 341 to rotate, and the arc-shaped rack 343 on the base ring 341 moves accordingly, meshing with the inner side of the driving spur gear 526, causing the driving spur gear 526 to rotate around the connecting shaft 524. The connecting shaft 524 drives the driving bevel gear 525 to rotate, and through meshing with the driven bevel gear 523, transmits power to the rotating shaft 521. The driven spur gear 353 at the front end of the rotating shaft 521 rotates and meshes with the internal gear ring 364 on the inner side of the annular inner rail 361, driving the annular inner rail 361 to rotate. The connecting ring 363 passes through the slip ring 36. 2. It is slidably connected to the annular inner rail 361. When the annular inner rail 361 rotates, it drives the connecting ring 363 to rotate. The fixing ring 371 fixed on the connecting ring 363 rotates accordingly. In the initial state, the cleaning scraper 376 is in contact with the mirror surface of the oral endoscope body 38, and multiple cleaning scrapers 376 form a concentric arc. When the fixing ring 371 rotates, it drives the sleeve 372, torsion spring 373, turntable 374 and other components to move. When the cleaning scraper 376 rotates in the opposite direction, its rotation direction is opposite to the torsion direction of the torsion spring 373. The contact friction between the oral endoscope body 38 and the cleaning scraper 376 drives the turntable 374 to rotate and compress the torsion spring 373. When the cleaning scraper 376 rotates to 90 degrees, the torsion spring 373 is compressed to the limit. The connecting ring 363 continues to rotate, and the cleaning scraper 376 strongly scrapes and cleans the fog, saliva and mucous membrane and other deposits on the surface of the endoscope body.

[0082] When the cleaning scraper 376 rotates clockwise, its direction is consistent with the return direction of the torsion spring 373. The torsion spring 373 quickly returns to its original position, causing the cleaning scraper 376 to retract to the edge of the housing 33. At the same time, the weighted ball 377 on the cleaning scraper 376 helps the cleaning scraper 376 to maintain its fit with the endoscope body, ensuring the cleaning effect. In addition, the lighting lamp 310 in the lamp holder 39 can be turned on by the button 19 on the control switch 18 to provide illumination for oral examination.

[0083] The workflow of the technical solution provided by this invention is as follows:

[0084] By setting up the support mechanism 1, the flexibility and convenience of using the oral endoscope can be effectively enhanced. During use, the second motor 16 is started, driving the lead screw 14 to rotate inside the rail frame 13. The slide rod 15 is slidably connected to the rail frame 13 and threadedly engaged with the lead screw 14. As the second motor 16 continues to operate, the lead screw 14 drives the slide rod 15 to slide linearly within the rail frame 13. The displacement of the slide rod 15 further pushes the rail frame 13, thereby driving the oral endoscope device 3 mounted on top of the rail frame 13 to achieve vertical displacement adjustment. Through this ingenious design, the length of the oral endoscope device 3 can be flexibly adjusted according to actual needs, whether for patients of different body types and oral structures, or to meet the needs of medical staff in different operating environments. The device is easily adaptable to various user habits. Medical staff can conveniently control the first motor 342, the second motor 16, or the lighting 310 by operating the control button 19 on the adjustment control switch 18. During oral examinations, turning on the lighting 310 provides sufficient light to illuminate the inside of the oral cavity. Combined with the reflection function of the oral mirror 38, it allows doctors to clearly observe the condition inside the oral cavity. Starting the first motor 342 allows for flexible adjustment of the rotation of the housing 33. By changing the angle of the housing 33, precise adjustments can be made to the reflection direction and angle, further enhancing the convenience of the device in clinical use and providing a more efficient and comfortable operating experience for oral examinations.

[0085] By setting up the oral endoscope device 3, automatic cleaning and multi-angle flexible adjustment functions can be realized during use. During use, the battery inside the housing 2 provides stable power to the entire device, ensuring the portable use of the device in different environments. When it is necessary to adjust the reflection angle of the oral endoscope, the first motor 342 is started. The motor drives the housing 33 to rotate, thereby flexibly changing the angle of the housing 33 and accurately adjusting the reflection direction to meet the observation needs of doctors in different examination sites.

[0086] More importantly, when the oral endoscope 38 fogs up due to temperature differences or is obstructed by saliva, mucous membranes, or other substances in the patient's mouth, this device demonstrates excellent cleaning capabilities. The reciprocating start of the first motor 342 not only drives the housing 33 to rotate, but also, during this rotation, the connecting shaft 524 on the mounting base 522 at the rear cover 351 rotates synchronously. The rotation of the connecting shaft 524 drives the driving spur gear 526 at its end to perform circular motion. The driving spur gear 526 meshes with the arc-shaped rack 343. As the first motor 342 drives the housing 33 to reciprocate, the driving spur gear 526, under the action of the arc-shaped rack 343, achieves reciprocating movement within a specific track while simultaneously rotating itself. The rotation of the driving spur gear 526 further drives the connecting shaft 524 to rotate, causing the driving bevel gear 525 to rotate synchronously. The driving bevel gear 525 meshes tightly with the driven bevel gear 523. The driven bevel gear 523 is provided with a protective shell on its outer side. The driving bevel gear 525 and the driven bevel gear 523 are rotatably connected inside the protective shell. The protective shell has a slot on the side where the driving bevel gear 525 and the driven bevel gear 523 are close to each other. The protective shell can protect the outer side of the driving bevel gear 525 and the driven bevel gear 523 without affecting their rotation. Driven by the driving bevel gear 525, the driven bevel gear 523 starts to rotate, which in turn drives the rotating shaft 521 to rotate synchronously. The rotation of the shaft 521 drives the driven spur gear 353 to rotate. The driven spur gear 353 interacts with the internal gear ring 364, driving the internal gear ring 364 to perform circular motion. The rotation of the internal gear ring 364 drives the connecting ring 363 to rotate synchronously. The connecting ring 363 is connected to the fixed ring 371, thereby assisting in driving the rotation of each fixed ring 371. A sleeve 372 is installed on the inner side of the fixed ring 371. As the fixed ring 371 rotates, the sleeve 372 drives each cleaning scraper 376 to rotate synchronously.

[0087] During the operation of the cleaning scraper 376, when the connecting ring 363 drives the cleaning scraper 376 to rotate in the opposite direction, the rotation direction of the cleaning scraper 376 is opposite to the torque direction of the torsion spring 373. Due to the elastic resistance of the torsion spring 373, in the initial stage of the rotation of the cleaning scraper 376, the dental endoscope body 38 drives the cleaning scraper 376 and the connected turntable 374 to rotate by the frictional force of the contact with the cleaning scraper 376. During the rotation of the turntable 374, the torsion spring 373 is compressed. When the cleaning scraper 376 rotates to 90 degrees, the torsion spring 373 is compressed to its limit, and the cleaning scraper 376 can no longer rotate under the torque. At this time, the connecting ring 363 continues to rotate, driving the cleaning scraper 376 to perform a strong scraping cleaning on the dental endoscope body 38, effectively removing the lens residue. When the connecting ring 363 drives the cleaning scraper 376 to swing to the other side, i.e., rotate in the same direction, the rotation direction of the cleaning scraper 376 is consistent with the reset direction of the torsion spring 373. The torsion spring 373 quickly resets, causing the cleaning scraper 376 to retract and rotate to the edge of the housing 33. Even without driving the connecting ring 363 to rotate in the opposite direction, the torsion spring 373 can slowly reset and retract the cleaning scraper 376 to the outside of the housing 33 to avoid obstructing the oral endoscope body 38. It can be seen that the first motor 342 drives the drive mechanism 34, the drive mechanism 34 drives the transmission mechanism 35, and the transmission mechanism 35 drives the linkage mechanism 36 to rotate through the transmission component 35, ultimately achieving efficient rotational cleaning of the cleaning scraper 376.

[0088] When the cleaning scraper 376 and the torsion spring 373 rotate in opposite directions, the cleaning scraper 376 unfolds and rotates, performing a comprehensive and meticulous scraping cleaning of the outer surface of the dental endoscope 38. When the first motor 342 drives the housing 33 to rotate the connecting ring 363 in reverse, the cleaning scraper 376, in conjunction with the torsion spring 373, resets and automatically rotates to be stored on the outside of the housing 33. In summary, through its ingenious structural design, this device achieves flexible multi-angle adjustment of the dental endoscope 38. With the coordinated operation of the drive mechanism 34, the transmission mechanism 35, and the linkage mechanism 36, the cleaning mechanism 37 is driven to perform efficient brushing cleaning of the outer surface of the dental endoscope 38. This design, which integrates angle adjustment and intelligent cleaning, greatly improves the convenience of this device in clinical use and provides more reliable and efficient technical support for dental diagnosis.
