Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to an oral mirror for clinical use in stomatology. Background Art

[0002] As one of the important classifications of medicine, stomatology covers many types of diseases, such as dermoid, submandibular space infection of the oral and maxillofacial region, lymphangioma of the maxillofacial region, odontoid process dysplasia, malignant tumor of the maxillary sinus, ameloblastoma of the jaw, chronic ethmoid sinusitis, mandibular retrognathia, tetracycline teeth, leukoplakia of the tongue, etc. Under the current medical technology conditions, many periodontal diseases are curable, and before treatment, a careful observation of the oral cavity with an oral mirror is a key step in accurately determining the condition.

[0003] Traditional oral mirrors mostly have a simple structure of a curved metal rod with an observation mirror. When in use, an additional lighting device is required to assist in lighting to meet the needs of clear observation and rapid diagnosis of the condition. To optimize the functions of the oral mirror, some innovative designs have emerged continuously. For example, the new type of oral mirror for clinical use in stomatology disclosed in the Chinese patent with the publication number CN216754418U realizes an improved lighting effect, adjustable use angle and length, and also has a limit function to prevent components from detaching by setting adjustment devices in the main body and structures such as struts, fixed blocks, connecting columns, connecting seats, and reflecting mirrors at relevant positions, providing more convenience for oral examinations.

[0004] However, in in-depth actual application scenarios, it will be found that the existing oral mirror technology still has obvious deficiencies. Due to the large temperature difference between the oral mirror and the oral cavity, the mirror is extremely prone to fogging after being put into the oral cavity, making it impossible for doctors to clearly observe the internal situation of the oral cavity. Currently, the commonly used anti-fog method of heating the oral mirror on an alcohol lamp has many drawbacks. On the one hand, heating with an alcohol lamp easily makes the mirror surface of the oral mirror contaminated with impurities and dirty, affecting the observation clarity; on the other hand, excessive heating may damage the oral mirror, and if the temperature of the mirror surface of the oral mirror is too high, there is also a risk of burning the patient's oral cavity when it is put into the oral cavity. In addition, during the process of inserting the oral mirror into the oral cavity, once the mirror body comes into contact with the inner wall of the oral cavity, substances such as saliva and mucosa in the oral cavity will adhere to it, blocking the mirror body and seriously affecting the overall observation effect, which has an adverse impact on the accuracy and efficiency of disease diagnosis. In view of this, there is an urgent need to improve the design of the oral mirror to overcome the defects of the existing technology. Summary of the Invention

[0034] The oral mirror of the present invention has the functions of automatic cleaning and multi-angle flexible adjustment.

This design enables doctors to flexibly observe various parts of the oral cavity, improves the inspection efficiency and accuracy, plays a key role in oral examination, provides strong support for the diagnosis work, and meets the diverse observation needs of clinical practice.

[0035] By setting up the bearing mechanism, the flexibility and convenience of using the oral endoscope can be effectively enhanced. During use, by starting the second motor, its precise power drives the lead screw to rotate stably within the rail frame. The sliding rod, due to its threaded fit with the lead screw and sliding within the rail frame, drives the rail frame and the oral endoscope device at the top to move up and down. This design can flexibly adjust the length of the oral endoscope according to actual needs, easily adapting to different patients and the operation habits of medical staff. Medical staff can conveniently control the first and second motors and the lighting lamp by adjusting the control switch. Turning on the lighting lamp and cooperating with the reflection of the mirror body facilitates the doctor to observe the oral cavity; starting the first motor can precisely adjust the angle of the housing, optimizing the clinical operation experience.

[0063] As Figures 1 to 9 shown, an embodiment of the present invention provides an oral mirror for clinical use in stomatology, the oral mirror comprising: a carrying mechanism 1, an oral mirror device 3, and an oral mirror body 38; a machine box 2 is fixedly installed at the top of the carrying mechanism 1; the oral mirror device 3 comprises: a concave seat 32, a housing 33, a driving mechanism 34, a transmission mechanism 35, a linkage mechanism 36, and a plurality of cleaning mechanisms 37; the concave seat 32 is fixedly installed at the top of the machine box 2, the housing 33 has a hollow cavity and is rotatably connected within the recessed area of the concave seat 32; the driving mechanism 34 is fixedly installed on the concave seat 32; the oral mirror body 38 is fixedly installed within the hollow cavity; the linkage mechanism 36 is in a ring structure and is movably installed on the side of the mirror surface of the oral mirror body 38 within the hollow cavity; the plurality of cleaning mechanisms 37 are arranged in a ring on the linkage mechanism 36; the linkage mechanism 36 is connected to the driving mechanism 34 through the transmission mechanism 35, and the driving mechanism 34 transmits driving force to the linkage mechanism 36 through the transmission mechanism 35 to drive the linkage mechanism 36 to drive the cleaning mechanisms 37 to rotate around the central axis of the housing 33, so as to perform circumferential cleaning on the mirror surface of the oral mirror body 38.

[0064] During the operation of this oral cavity mirror used in the dental clinic, a storage battery is installed inside the machine box 2 to supply power to the entire device. When it is necessary to clean the mirror surface of the oral cavity mirror body 38, the driving mechanism 34 fixedly installed on the concave seat 32 is started, and the driving force generated by the driving mechanism 34 is transmitted to the linkage mechanism 36 through the transmission mechanism 35. The linkage mechanism 36 is in a ring structure and is movably installed on one side of the hollow cavity of the housing 33 close to the mirror surface of the oral cavity mirror body 38. After receiving the power transmitted by the transmission mechanism 35, the linkage mechanism 36 starts to rotate around the central axis of the housing 33. Since a plurality of 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 on the mirror surface of the oral cavity mirror body 38, effectively removing attachments such as fog, saliva, and mucosa on the mirror surface, ensuring the clarity of the mirror surface, and providing a good visual field for oral cavity examinations.

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

[0066] When this oral cavity mirror is working, the first motor 342 fixed to one side of the concave seat 32 is started, and the first motor 342 outputs power to drive the base ring 341 connected to it to perform a rotational motion. During the rotation of the base ring 341, the arc-shaped rack 343 fixed to the inner side wall of its inner ring moves accordingly. The arc-shaped rack 343 is engaged with the gear assembly, transmits the motion to the gear assembly, and causes the gear assembly to rotate. The gear assembly is also engaged with the internal gear ring 364 fixed to the inner side 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, and a plurality of 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 cavity mirror body 38, removing various attachments on the mirror surface, ensuring the clarity of the mirror surface, and providing convenience for oral cavity examinations.

[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 coupling 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 coupling shaft 524 is rotatably connected to the mounting base 522; the driving bevel gear 525 is fixedly connected to one end of the coupling shaft 524, the driving spur gear 526 is fixedly connected to the other end of the coupling shaft 524, the driving spur gear 526 is meshed and connected to the inner side of the arc-shaped rack 343, and the driving bevel gear 525 is meshed and connected to the driven bevel gear 523.

[0068] When the first motor 342 in the driving 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 is meshed with the inner side of the driving spur gear 526 to drive 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 coupling shaft 524. Since the driving bevel gear 525 is meshed with the driven bevel gear 523, the rotation of the driving bevel gear 525 is transmitted to the driven bevel gear 523, thereby driving the rotating shaft 521 connected thereto 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 is meshed with the internal gear ring 364 fixed to the inner side wall of the inner ring of the linkage mechanism 36 to transmit power to the internal gear ring 364, driving the linkage mechanism 36 to rotate around the central axis of the housing 33, and finally realizing the circumferential cleaning of the mirror surface of the endoscope body 38 by the cleaning mechanism 37 mounted on the linkage mechanism 36.

[0069] As Figures 8 to 9 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 side of the endoscope body 38 that is not the mirror surface, and the mounting base 522 is mounted on the rear cover 351. The rear cover 351 can be mounted on the back of the housing by screws. The rear cover 351 is used to cover and protect the endoscope body 38, and the endoscope body 38 is disposed on the front surface 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 side wall of the housing 33, the internal gear ring 364 is mounted on the annular inner rail 361, and the annular inner rail 361 is driven to rotate by 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 to drive the cleaning mechanism 37 to rotate.

[0071] When the driving mechanism 34 is activated to drive 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, 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, thereby driving the rotating shaft 521 fixedly connected thereto to rotate. The driven spur gear 353 at the front end of the rotating shaft 521 rotates driven by the rotating shaft 521 and meshes with the internal gear ring 364 installed on the annular inner track 361, transmitting power to the internal gear ring 364, thereby driving the annular inner track 361 to rotate around the central axis of the housing 33. The connecting ring 363 is slidably connected to the annular inner track 361 through the slip ring 362. When the annular inner track 361 rotates, with the sliding cooperation of the slip ring 362, the connecting ring 363 is driven to rotate. Since the cleaning mechanism 37 is installed on the connecting ring 363, the rotation of the connecting ring 363 finally realizes the rotation of the cleaning mechanism 37 around the central axis of the housing 33, completing the circumferential cleaning of the mirror surface of the endoscope body 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 shape 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 thereof is connected to the turntable 374; one end of the connecting arm 375 is fixedly connected to the turntable 374, and a cleaning scraper 376 is installed at the other end thereof; the cleaning scraper 376 is attached to the mirror surface of the endoscope body 38. A connecting arm 375 is fixedly connected to one side of the turntable 374, and a cleaning scraper 376 is fixedly installed at the rear end of the connecting arm 375. The back surface of the cleaning scraper 376 is attached to the front surface of the endoscope body 38.

[0073] The cleaning mechanism 37 may further include: a weight ball 377; the weight ball 377 is installed at one end of the cleaning scraper 376 away from the sleeve 372.

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

[0075] In some embodiments, lamp holders 39 are fixedly connected to the outside of the housing 33 at equal intervals. An illuminating lamp 310 is fixedly connected to the inside of the lamp holder 39. The illuminating lamp 310 is electrically connected to the storage battery inside the machine box 2 through a wire. The hollow wire tube sleeve 31 is fixedly connected to the top of the machine box 2, and the concave seat 32 is fixedly installed on the top of the hollow wire tube sleeve 31.

[0076] When using this oral cavity mirror for clinical use in stomatology, the storage battery inside the machine box 2 supplies power to the lighting lamp 310 in the lamp holder 39 through a wire. After the user turns on the power, the lighting lamp 310 lights up, illuminating the internal environment of the oral cavity and providing sufficient light for oral cavity examination. At the same time, the driving mechanism 34 fixed on one side of the concave seat 32 starts. The power generated by the driving mechanism 34 is transmitted to the linkage mechanism 36 movably installed inside the housing 33 through the transmission mechanism 35 arranged on the back of 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 oral cavity mirror body 38 fixedly installed on the front of the transmission mechanism 35. The housing 33 rotatably connected inside the concave seat 32 can flexibly adjust the angle during the examination, cooperate with the lighting lamp 310 and the cleaning mechanism 37 to ensure that the oral cavity mirror body 38 always maintains a clear field of view, provides good observation conditions for doctors, and helps to efficiently complete the oral cavity examination work.

[0077] In some embodiments, the carrying mechanism 1 may include: a base plate 11, a frame body 12, a rail frame 13, a lead screw 14, a slide rod 15 and a second motor 16; the frame body 12 is installed on the top of the base plate 11, and the rail frame 13 is installed on the top of the frame body 12; the rail frame 13 has a movable through hole, and the lead screw 14 is rotatably connected in the movable through hole; one end of the slide rod 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 body 12 has an inner cavity, the second motor 16 is installed in the inner cavity, and the output end of the second motor 16 penetrates through the frame body 12 and extends into the movable through hole to be connected to the end of the lead screw 14 to drive the lead screw 14 to rotate.

[0078] In some embodiments, the carrying mechanism 1 may further include: an operation armrest 17, an anti-slip armrest glove and a control switch 18; the operation armrest 17 is installed at the bottom of the base plate 11, and the anti-slip armrest glove is sleeved on the outer surface of the operation armrest 17; the control switch 18 is installed on one side of the operation 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 a button 19 is provided on the control switch 18.

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

[0080] When the oral mirror for clinical use in stomatology works, the button 19 on the control switch 18 on one side of the operation armrest 17 is manipulated to start the second motor 16. The output end of the second motor drives the lead screw 14 to rotate in the movable through hole of the rail frame 13. Since the inner cavity of the rail frame 13 and the cross section of the slide bar 15 are regular hexagons, one end of the slide bar 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 bar 15 can only slide linearly along the lead screw 14, thereby driving the concave seat 32 and the entire oral mirror device 3 to move up and down to achieve height adjustment.

[0081] When it is necessary to clean the oral mirror body 38, the corresponding button 19 on the control switch 18 is pressed 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. Through meshing with the driven bevel gear 523, the power is transmitted 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 is slidably connected to the annular inner rail 361 through the slip ring 362. 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. The cleaning scraper 376 is initially in contact with the mirror surface of the oral mirror body 38, and multiple cleaning scrapers 376 form concentric arcs. When the fixing ring 371 rotates, it drives components such as the sleeve 372, the torsion spring 373, and the turntable 374 to move. When the cleaning scraper 376 rotates reversely, its rotation direction is opposite to the torsion direction of the torsion spring 373. The frictional force of the contact between the oral mirror 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 attachments such as fog, saliva, and mucosa on the surface of the mirror body.

[0082] When the cleaning scraper 376 rotates forward, its direction is consistent with the reset direction of the torsion spring 373. The torsion spring 373 quickly resets, driving the cleaning scraper 376 to retract to the edge of the housing 33. At the same time, the weight ball 377 on the cleaning scraper 376 helps the cleaning scraper 376 to maintain contact with the mirror body to ensure the cleaning effect. In addition, the illuminating lamp 310 in the lamp holder 39 can be turned on through the button 19 on the control switch 18 to provide illumination for oral examination.

[0083] The working process of the technical solution provided by the present invention is as follows:

[0084] By setting up the bearing mechanism 1, the flexibility and convenience of using the oral endoscope can be effectively enhanced. During use, start the second motor 16 to drive the lead screw 14 to rotate inside the rail frame 13. The slide bar 15 is slidably connected to the rail frame 13 and is threadedly engaged with the lead screw 14 at the same time. As the second motor 16 continues to operate, the lead screw 14 drives the slide bar 15 to linearly slide inside the rail frame 13. The displacement of the slide bar 15 further pushes the rail frame 13, thereby driving the oral endoscope device 3 installed at the top of the rail frame 13 to achieve vertical displacement adjustment. Through this delicate design, this device can flexibly adjust the length of the oral endoscope device 3 according to actual needs. Whether it is dealing with patients of different body types and oral structures or meeting the habits of medical staff in different operation scenarios, it can be easily adapted. Medical staff only need to operate the control buttons 19 on the adjustment control switch 18 to conveniently control the first motor 342, the second motor 16 or the lighting lamp 310 respectively. During oral examination, turn on the lighting lamp 310, which can provide sufficient light assistance to illuminate the inside of the oral cavity. With the reflection function of the oral endoscope body 38, doctors can clearly observe the internal conditions of the oral cavity. Start the first motor 342 to operate, and the rotation of the housing 33 can be flexibly adjusted. By changing the angle of the housing 33, the reflection direction and angle can be accurately adjusted, further enhancing the convenience of this device in clinical use and providing a more efficient and comfortable operation experience for oral examination work.

[0085] By setting up the oral endoscope device 3, the functions of automatic cleaning and multi-angle flexible adjustment can be realized during use. During the use process, the storage battery inside the machine box 2 stably powers 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, start the first motor 342. The operation of the motor drives the housing 33 to rotate, so that the angle of the housing 33 can be flexibly changed, and the reflection direction can be accurately adjusted to meet the observation needs of doctors at different examination sites.

[0086] More importantly, when the endoscope body 38 generates fog due to temperature difference, or is blocked by substances such as saliva and mucous membranes in the patient's oral cavity, the device demonstrates excellent cleaning function. The first motor 342 is started reciprocally, and the power generated by it not only drives the housing 33 to rotate. During the rotation process, as the housing 33 rotates, the coupling shaft 524 on the mounting seat 522 at the rear cover 351 rotates synchronously. The rotation of the coupling 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 rotate reciprocally, the driving spur gear 526 realizes reciprocating movement within a specific track under the action of the arc-shaped rack 343, while rotating itself. The rotation of the driving spur gear 526 further drives the coupling shaft 524 to rotate. The rotation of the coupling shaft 524 causes the driving bevel gear 525 to rotate synchronously. The driving bevel gear 525 meshes tightly with the driven bevel gear 523. Protective shells are provided on the outer sides of both the driving bevel gear 525 and the driven bevel gear 523. Both the driving bevel gear 525 and the driven bevel gear 523 are rotatably connected inside the protective shell. The protective shell is provided with a notch 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 sides of the driving bevel gear 525 and the driven bevel gear 523 while not affecting their rotation. Driven by the driving bevel gear 525, the driven bevel gear 523 starts to rotate, and then synchronously drives the rotating shaft 521 to rotate. The rotation of the rotating shaft 521 drives the driven spur gear 353 to rotate. The driven spur gear 353 interacts with the internal gear ring 364 to drive 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 also connected to the fixed ring 371, thereby assisting in driving each fixed ring 371 to rotate. A sleeve 372 is installed inside 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 squeegee 376, when the connecting ring 363 drives the cleaning squeegee 376 to rotate reversely, the rotation direction of the cleaning squeegee 376 is opposite to the torsion direction of the torsion spring 373. Due to the certain elastic resistance of the torsion spring 373, at the initial stage of the rotation of the cleaning squeegee 376, the oral endoscope body 38 drives the cleaning squeegee 376 and the turntable 374 connected thereto to rotate by virtue of the fitting friction with the cleaning squeegee 376. During the rotation of the turntable 374, the torsion spring 373 is compressed. When the cleaning squeegee 376 rotates to 90 degrees, the torsion spring 373 is compressed to the limit state, and the cleaning squeegee 376 cannot continue to rotate under the action of the torsion force. At this time, the connecting ring 363 continues to rotate, driving the cleaning squeegee 376 to strongly scrape and clean the oral endoscope body 38, effectively removing attachments such as fog, saliva and mucosa on the surface of the endoscope body. When the connecting ring 363 drives the cleaning squeegee 376 to swing towards the other side, that is, to rotate forward, the rotation direction of the cleaning squeegee 376 is the same as the reset direction of the torsion spring 373, and the torsion spring 373 quickly resets, driving the cleaning squeegee 376 to retract and rotate, so that it rotates to the edge of the housing 33. Even if the connecting ring 363 is not driven to rotate reversely, the slow reset of the torsion spring 373 can also retract the cleaning squeegee 376 to the outside of the housing 33 to avoid blocking the oral endoscope body 38. It can be seen that by driving the driving mechanism 34 by the first motor 342, the driving mechanism 34 drives the transmission mechanism 35, and the transmission mechanism 35 drives the linkage mechanism 36 to rotate through the transmission assembly 35, and finally realizes the efficient rotary cleaning of the cleaning squeegee 376.

[0088] When the cleaning squeegee 376 rotates reversely with the torsion spring 373, the cleaning squeegee 376 unfolds and rotates to comprehensively and carefully scrape and clean the outer surface of the oral endoscope body 38; when the first motor 342 drives the housing 33 to drive the connecting ring 363 to reverse, the cleaning squeegee 376 cooperates with the reset of the torsion spring 373 and automatically rotates and retracts to the outside of the housing 33. In summary, through the ingenious structural design of the present device, while realizing the multi-angle flexible adjustment of the oral endoscope body 38, with the coordinated cooperation of the driving mechanism 34, the transmission mechanism 35 and the linkage mechanism 36, the cleaning mechanism 37 is driven to efficiently brush and clean the outer surface of the oral endoscope body 38. This design that integrates angle adjustment and intelligent cleaning greatly improves the convenience of the present device in clinical use and provides more reliable and efficient technical support for the diagnosis work in the stomatology department.
