When the observation orientation requires adjustment, the adjustment mechanism (3) is operated, so as to adjust the observation direction of the observation position (11-11), thereby always ensuring effective observation by directing the observation lens (200) to the lateral tooth surface and observation in all directions of the periodontium, and featuring good application prospects. The arrangement of the lens sleeve (100) on the adjustable periodontal endoscope allows observation in all directions of the periodontium without moving the handle (2) in the process of clinical use, featuring ease to use.

Description

Adjustable periodontal endoscope sleeve and adjustable periodontal endoscope Technical Field

[0001] The invention relates to an auxiliary instrument for oral treatment, in particular to an adjustable periodontal endoscope sleeve and an adjustable periodontal endoscope used in conjunction with a periodontal endoscope. Background Art

[0002] Periodontal disease, especially periodontitis, is currently the most common oral disease. If left untreated, the disease can progress and lead to symptoms such as bleeding gums, periodontal pockets, abscesses, and loose teeth. The primary cause of periodontitis is tartar and plaque that form on 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 in the periodontal pocket.

[0004] The current common treatment process is to use a fine subgingival scaler to scrape around the root surface of the tooth based on the reflection of the mouth mirror and the feel of the hand to remove the diseased tissue on the root surface and scattered tartar and plaque, so as to make the root surface smooth. During or after the scaling operation, a pointed probe must be used to carefully explore 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 scaling is performed solely by the reflection of a dental mirror and feel, it is difficult to clearly observe the scaling process within the periodontal pocket, which can easily lead to tissue damage or incomplete scaling. To avoid this, periodontal endoscopes are now being used to assist in the subgingival scaling process.

[0006] Current periodontal endoscopes are usually provided with a lens sleeve, the outlet end of which is a tapered slope facing the tooth side. The endoscope extends from the outlet end of the lens sleeve and faces the tooth side for observation.

[0007] Currently, the structure and angle between the conical bevel at the outlet of the lens sleeve and the handle are fixed. Therefore, during the observation process, the conical bevel may not be properly oriented towards the tooth side due to the limitation of the handle, thereby affecting the observation effect. Therefore, the current lens sleeve needs to be improved for better clinical use. Summary of the Invention

[0008] The adjustable periodontal endoscope cover of the present invention can adjust the direction of the conical surface at the outlet of the cover through the adjustment mechanism provided on the cover, thereby solving the problem that the conical surface at the outlet of the cover cannot be oriented toward the tooth side due to the limitation of the handle in current clinical use, and has a wider range of applicability in clinical use.

[0009] The adjustable periodontal endoscope cover of the present invention is characterized in that: the adjustable periodontal endoscope cover 100 comprises a sleeve 1, a gripping portion 2 and an adjustment mechanism 3;

[0010] A. The cannula 1 includes a working channel 11, and an outlet 11-1 of the working channel 11 is provided with an observation position 11-11;

[0011] B. The proximal end of the cannula 1 is connected to the gripping portion 2;

[0012] C. The adjusting mechanism 3 is connected to the sleeve 1. When the adjusting mechanism 3 is adjusted, the observing direction of the observing position 11-11 of the sleeve 1 changes accordingly;

[0013] D. The observation mirror 200 enters the working channel 11 through the inlet 11 - 2 of the working channel 11 and observes the tissue at the observation position 11 - 11 through the outlet 11 - 1 of the working channel 11 .

[0014] Since the adjustment mechanism 3 can adjust the observation direction of the observation position 11-11, the holding portion 2 only needs to be placed at a suitable position at the corner of the mouth during use, and does not need to be adjusted according to the observation angle. When the observation angle needs to be adjusted, the adjustment mechanism 3 is adjusted to adjust the observation direction of the observation position 11-11, thereby ensuring that the observation mirror 200 is always facing the side surface of the tooth for effective observation. The placement position of the holding portion 2 does not need to be adjusted during clinical use, and certain parts will not be unable to be effectively observed due to the limitation of the holding portion 2. Observation of all directions of the periodontium can be achieved during clinical use, and the applicability is very wide.

[0015] The distal end of the outlet 11-1 is provided with a probe 11-12. The probe 11-12 is generally made into a probe-like component with a smooth tip, which can penetrate into the periodontal pocket for detection, better expose the operation field of the treatment process, and achieve better operation observation.

[0016] The adjustment mechanism 3 adjusts the direction of the observation position 11-11 of the outlet 11-1 by rotation. This rotational adjustment method allows for 360° adjustment, is simple to operate, and has a wide adjustment range. The rotational adjustment method can be achieved through various specific structures, such as interference fit rotation of the inner and outer sleeves, ratchet rotation, and thread rotation.

[0017] The adjustment mechanism 3 includes an inner tube mechanism 31 and an outer tube mechanism 32. The outer tube mechanism 32 is sleeved on the outer side of the inner tube mechanism 31. The inner tube mechanism 31 and the outer tube mechanism 32 rotate relative to each other to adjust the direction of the observation position 11-11 of the outlet 11-1. This inner-outer arrangement of the inner tube mechanism 31 and the outer tube mechanism 32 allows the direction of the observation position 11-11 to be adjusted through simple relative movement of the inner and outer sleeves, which is not only convenient to operate but also very simple in structure.

[0018] The adjustment mechanism 3 is a ratchet adjustment mechanism 301 .

[0019] The inner tube mechanism 31 is arranged at the proximal end of the sleeve 1, and a ratchet 31-1 is provided on the outside; the outer tube mechanism 32 is arranged at the proximal end of the gripping portion 2, and a pawl mechanism 32-1 is provided on the inside; the ratchet 31-1 is provided with at least two positioning grooves 31-11, and when the ratchet 31-1 is rotated, the pawl mechanism 32-1 disengages from the positioning groove 31-11, and the sleeve 1 rotates accordingly. After rotating to the position to be adjusted, the pawl mechanism 32-1 is again embedded in the positioning groove 31-11 of the ratchet 31-1 to form a positioning, and the direction of the observation position 11-11 is adjusted and determined accordingly. This ratchet adjustment method is not only very convenient to rotate, but also the size of the ratchet can be set according to the required adjustment accuracy, and can be easily adjusted according to the set adjustment angle. In addition, the ratchet structure has a good positioning effect, which can effectively fix the observation direction of the observation position 11-11.

[0020] The ratchet adjustment mechanism 301 is a one-way ratchet adjustment mechanism 301 - 1 .

[0021] The positioning groove 31-11 of the ratchet 31-1 is an asymmetric positioning groove 31-11-1, and the pawl mechanism 32-1 is an asymmetric positioning block 32-11. The asymmetric positioning groove 31-11-1 and the asymmetric positioning block 32-11 together constitute the one-way ratchet adjustment mechanism 301-1. This asymmetric one-way structure can prevent accidental rotation and ensure the angle adjustment direction.

[0022] The ratchet adjustment mechanism 301 is a bidirectional ratchet adjustment mechanism 301 - 2 .

[0023] The positioning groove 31-11 of the ratchet 31-1 is a symmetrical positioning groove 31-11-2, and the pawl mechanism 32-1 is a symmetrical positioning block 32-12. The symmetrical positioning groove 31-11-2 and the symmetrical positioning block 32-12 together constitute the bidirectional ratchet adjustment mechanism 301-2. The symmetrical structure allows for free bidirectional rotation during use, making it very convenient to use.

[0024] The adjustment mechanism 3 is an interference fit adjustment mechanism 302 .

[0025] The inner tube mechanism 31 is arranged at the proximal end of the sleeve 1 and is made of elastic material. The outer tube mechanism 32 is arranged at the proximal end of the gripping part 2. Hold the gripping part 2 and rotate the inner tube mechanism 31. The inner tube mechanism 31 overcomes the friction force of the outer tube mechanism 32 and rotates. The sleeve 1 rotates accordingly to the required direction and stops rotating. Under the action of friction, the inner tube mechanism 31 is fixed, and the direction of the observation position 11-11 is adjusted and determined accordingly.

[0026] The interference fit rotation adjustment method achieves positioning through the friction between the inner tube mechanism 31 and the outer tube mechanism 32. Since there is no positioning convex step, the direction of the observation position 11-11 can be adjusted steplessly. The direction of the observation position 11-11 can be adjusted to any angle as needed, which is very convenient for clinical use. In order to avoid the friction of the entire plane between the inner tube mechanism 31 and the outer tube mechanism 32, which causes the friction force to cause rotation difficulties, a friction block 32-3 can be provided on the outer tube mechanism 32. The size of the friction force is adjusted by setting the size of the contact area between the friction block 32-3 and the inner tube mechanism 31, thereby ensuring that the friction force can achieve positioning between the inner tube mechanism 31 and the outer tube mechanism 32, and will not be too large to cause rotation difficulties.

[0027] The adjustable periodontal endoscope sheath 100 is also equipped with an axial motion limiting mechanism 4. During use, the cannula 1 must be inserted into the periodontal pocket and maintained deep within the pocket to ensure that the viewing scope 200 can observe the tooth flanks within the pocket. Therefore, during use, the cannula 1 is under stress and must be prevented from axially shifting up or down. The axial motion limiting mechanism 4 limits the axial movement of the cannula 1, preventing it from shifting upward during use, which would cause the viewing scope 200 to shift upward and prevent observation within the periodontal pocket.

[0028] The inner tube mechanism 31 of the adjustment mechanism 3 is provided with an axial limit groove 31-2, forming the axial motion limiting mechanism 4. The outer sleeve mechanism 32 is embedded in the axial limit groove 31-2. When the grip portion 2 is grasped, the sleeve 1 cannot move axially. The outer sleeve mechanism 32 is fixedly connected to the grip portion 2. When embedded in the axial limit groove 31-2, the sleeve 1 is also restricted from movement due to the grip portion 2 being held in the user's hand. This concave-convex snap-fit ​​design, through the limiting effect of the axial limit groove 31-2, results in a very simple structure.

[0029] The angle β between the gripping portion 2 and the sleeve 1 is adjusted by the angle adjustment mechanism 5. The angle β can be adjusted by the angle adjustment mechanism 5 as needed to adapt to different periodontal and tooth shapes and angles.

[0030] The angle adjustment mechanism 5 is a shaping mechanism 51 provided at the distal end of the gripping portion 2 .

[0031] The shaping mechanism 51 is integrally manufactured from a plastic material. Typically, the shaping mechanism 51 is made of a plastic metal, which ensures both a good shaping effect and good strength, maintaining stability during use. This integral manufacturing method of a plastic material allows the structure of the grip 2 to remain simple and is very convenient for adjustment during clinical use.

[0032] The adjustable periodontal endoscope sleeve 100 is further provided with an identification mechanism 6 .

[0033] The identification mechanism 6 is provided on the detection portion 11-12 at the distal end of the outlet 11-1 and / or on the adjustment mechanism 3. The identification mechanism 6 can be a length scale provided on the detection portion 11-12 at the distal end of the outlet 11-1, allowing the detection portion 11-12 to function as a probe, enabling the depth of the periodontal pocket to be visually read through the observation mirror 200. The identification mechanism 6 can also be an angle scale provided on the adjustment mechanism 3, allowing the adjustment angle of the observation position 11-11 to be identified by observing the rotation angle of the adjustment mechanism 3.

[0034] The distal end of the sleeve 1 is in a conical structure, which enables the distal end of the sleeve 1 to easily penetrate deep into the periodontal pocket.

[0035] The inlet 11 - 2 of the working channel 11 is trumpet-shaped, which makes it easier for the sight glass 200 to be inserted into the sleeve 1 .

[0036] During clinical use, the observation mirror 200 is inserted into the working channel 11 of the sleeve 1 through the inlet 11-2, the distal end of the sleeve 1 is inserted into the periodontal pocket, and the observation mirror 200 is extended from the outlet 11-1 to observe the tooth side. When the observation direction needs to be adjusted, the adjustment mechanism 3 is rotated to adjust the observation direction of the observation position 11-11 as needed.

[0037] The adjustable periodontal endoscope of the present invention is characterized in that the adjustable periodontal endoscope 900 comprises the observation lens 200 and the adjustable periodontal endoscope cover 100. The observation lens 200 and the adjustable periodontal endoscope cover 100 can be manufactured as a whole to form the adjustable periodontal endoscope 900.

[0038] The observation scope 200 is a fiber-optic observation scope 201. The handle 2 includes a housing 21, which houses a light source 22 and a circuit system 23. The light source 22 provides illumination for the fiber-optic observation scope 201, and the circuit system 23 connects the observation scope 200 to a main unit 202 of the observation scope 200. The distal end of the observation scope 200 is disposed within the sleeve 1, and the adjustable periodontal endoscope sleeve 100 adjusts the viewing direction of the observation position 11-11 to ensure that the observation scope 200 can observe the tooth side effectively. For miniature periodontal endoscopes, such as those with a diameter of 1 mm or less, the illumination method of the observation scope 200 is typically fiber-optic illumination. In the present invention, this type of endoscope using fiber-optic illumination is referred to as the fiber-optic observation scope 201. Because optical fibers are easily broken and require side shielding during use, the light source is typically located close to the observation end, such as within the housing 21 of the handle 2. The circuit system 23 is connected to the host 202 and provides power to the light source 22 . The light source 22 provides illumination to the observation scope 200 through light-guiding optical fibers to ensure the normal operation of the observation scope 200 .

[0039] Because the adjustable periodontal endoscope 900 includes the adjustable periodontal endoscope cover 100, the direction of the observation position 11-11 can be adjusted during use via the adjustment mechanism 3 without adjusting the position and direction of the grip 2. Therefore, during clinical use, observation of the periodontium in all directions can be achieved without moving the grip 2, thus providing a wide range of applications.

[0040] The adjustable periodontal endoscope sleeve of the present invention includes a sleeve 1, a gripping portion 2 and an adjusting mechanism 3. The sleeve 1 includes a working channel 11, and the outlet 11-1 of the working channel 11 is provided with an observation position 11-11. The observation mirror 200 enters the working channel 11 through the inlet 11-2 of the working channel 11, and observes the tissue at the observation position 11-11 through the outlet 11-1 of the working channel 11. The adjusting mechanism 3 is connected to the sleeve 1, and the observation direction of the observation position 11-11 of the sleeve 1 changes accordingly by adjusting the adjusting mechanism 3. During use, there is no need to adjust the position and direction of the gripping portion 2. When the observation angle needs to be adjusted, the adjusting mechanism 3 is adjusted, and the observation direction of the observation position 11-11 is adjusted to ensure that the observation mirror 200 always faces the tooth side for effective observation, thereby realizing observation in all directions of the periodontium, and having a very wide range of applications. Since the adjustable periodontal endoscope of the present invention is provided with the adjustable periodontal endoscope cover 100 of the present invention, observation of the periodontium in all directions can be achieved without moving the gripping portion 2 during clinical use, which is very convenient to use.

DETAILED DESCRIPTION

[0079] Example 1: Adjustable periodontal endoscope sleeve of the present invention with a one-way ratchet adjustment mechanism

[0080] 1 to 2-5 , in this embodiment, the adjustable periodontal endoscope sheath 100 includes a sheath 1 , a gripping portion 2 and an adjusting mechanism 3 .

[0081] Referring to Figures 1-2, 1-3, 2-2, and 2-3, the cannula 1 includes a working channel 11, and an observation position 11-11 is provided at the outlet 11-1 of the working channel 11. A detection portion 11-12 is provided at the distal end of the outlet 11-1. The detection portion 11-12 is typically formed as a probe-like component with a smooth tip, which can penetrate deep into the periodontal pocket for detection, better exposing the operating field of view during the treatment process and enabling better observation of the operation. The inlet 11-2 of the working channel 11 is trumpet-shaped, and this trumpet-shaped entrance shape makes it easier to insert the observation scope 200 into the cannula 1.

[0082] 1 and 2 , the distal end of the sleeve 1 is in a conical structure, which enables the distal end of the sleeve 1 to be easily inserted into the depth of the periodontal pocket.

[0083] The adjusting mechanism 3 is connected to the sleeve 1 , and the observing direction of the observing position 11 - 11 of the sleeve 1 is changed accordingly by adjusting the adjusting mechanism 3 .

[0084] In this embodiment, the adjustment mechanism 3 adjusts the direction of the observation position 11-11 of the outlet 11-1 by rotation. This rotational adjustment method allows for 360° adjustment, simplifies operation, and provides a wide adjustment range. Rotational adjustment can be achieved through various specific structures, such as interference fit rotation of the inner and outer sleeves, ratchet rotation, or threaded rotation.

[0085] Referring to Figures 1-4 and 2-4, the adjustment mechanism 3 includes an inner tube mechanism 31 and an outer tube mechanism 32. The outer tube mechanism 32 is sleeved on the outer side of the inner tube mechanism 31. The inner tube mechanism 31 and the outer tube mechanism 32 rotate relative to each other to adjust the direction of the observation position 11-11 of the outlet 11-1. This inner-outer arrangement of the inner tube mechanism 31 and the outer tube mechanism 32 allows the direction of the observation position 11-11 to be adjusted through simple relative movement of the inner and outer sleeves, which is not only convenient to operate but also very simple in structure.

[0086] In this embodiment, the adjustment mechanism 3 is a ratchet adjustment mechanism 301 .

[0087] Referring to Figures 1-4 and 2-4, the inner tube mechanism 31 is arranged at the proximal end of the sleeve 1, and a ratchet 31-1 is provided on the outside; the outer tube mechanism 32 is arranged at the proximal end of the grip portion 2, and a pawl mechanism 32-1 is provided on the inside; the ratchet 31-1 is provided with at least two positioning grooves 31-11. When the ratchet 31-1 is rotated, the pawl mechanism 32-1 disengages from the positioning grooves 31-11, and the sleeve 1 rotates accordingly. After rotating to the position to be adjusted, the pawl mechanism 32-1 is again embedded in the positioning grooves 31-11 of the ratchet 31-1 to form a positioning, and the direction of the observation position 11-11 is adjusted and determined accordingly. This ratchet adjustment method is not only very convenient to rotate, but also the size of the ratchet can be set according to the required adjustment accuracy, and can be easily adjusted according to the set adjustment angle. In addition, the ratchet structure has a good positioning effect, which can effectively fix the observation direction of the observation position 11-11.

[0088] 1-4 and 2-4 , in this embodiment, the ratchet adjustment mechanism 301 is a one-way ratchet adjustment mechanism 301 - 1 .

[0089] The positioning groove 31-11 of the ratchet 31-1 is an asymmetric positioning groove 31-11-1, and the pawl mechanism 32-1 is an asymmetric positioning block 32-11. The asymmetric positioning groove 31-11-1 and the asymmetric positioning block 32-11 together constitute the one-way ratchet adjustment mechanism 301-1. This asymmetric one-way structure can prevent accidental rotation and ensure the angle adjustment direction.

[0090] 1-4 and 2-4 , in order to ensure the movement space of the ratchet 31 - 1 during the rotation process, a deformation groove 32 - 2 is provided on the outer sleeve mechanism 32 .

[0091] Referring to Figures 1 and 1-4, the pawl mechanism 32-1 can be an integral structure arranged on the inner side of the outer sleeve 32 to better ensure the positioning effect; it can also be a local structure arranged on the inner side of the outer sleeve 32 to reduce the movement resistance while ensuring the positioning effect, referring to Figures 2 and 2-4.

[0092] With reference to Figures 1-2 and 2-2, in this embodiment, the outer sleeve mechanism 32 is integrally manufactured with the gripping portion 2. An axial limit groove 31-2 is provided on the inner tube mechanism 31 to constitute an axial movement limiting mechanism 4. The outer sleeve mechanism 32 is embedded in the axial limit groove 31-2. When the gripping portion 2 is held, the sleeve 1 cannot move in the axial direction. Since the outer sleeve mechanism 32 is fixedly connected to the gripping portion 2, when embedded in the axial limit groove 31-2, the sleeve 1 is also restricted from moving because the gripping portion 2 is held in the hand of the user. This concave-convex card-fitting inlay method, through the limiting effect of the axial limit groove 31-2, has a very simple structure.

[0093] During use of the adjustable periodontal endoscope sleeve 100, the sleeve 1 must be inserted into the periodontal pocket and maintained deep within the pocket to ensure that the viewing scope 200 can observe the tooth side within the pocket. Therefore, during use, the sleeve 1 is under stress, and therefore, it is necessary to ensure that the sleeve 1 does not shift axially up and down. The axial movement limiting mechanism 4 can limit the axial movement of the sleeve 1, preventing the sleeve 1 from shifting upward during use, thereby causing the viewing scope 200 to shift upward and become unable to observe within the periodontal pocket.

[0094] 6 to 6-2 , in this embodiment, the angle β between the grip portion 2 and the sleeve 1 can also be adjusted by the angle adjustment mechanism 5. The angle β can be adjusted by the angle adjustment mechanism 5 as needed to adapt to different periodontal and tooth shapes and angles.

[0095] The angle adjustment mechanism 5 is a shaping mechanism 51 provided at the distal end of the gripping portion 2. Referring to Figure 6-1, in this embodiment, the shaping mechanism 51 and the gripping portion 2 are installed together via a threaded connection.

[0096] The shaping mechanism 51 is integrally manufactured from a plastic material. Typically, the shaping mechanism 51 is made of a plastic metal, which ensures both a good shaping effect and good strength, maintaining stability during use. This integral manufacturing method of a plastic material allows the structure of the grip 2 to remain simple and is very convenient for adjustment during clinical use.

[0097] 7 and 7-1 , in this embodiment, the identification mechanism 6 is provided on the detection portion 11 - 12 at the distal end of the outlet 11 - 1 and on the adjustment mechanism 3 . The adjustable periodontal endoscope sleeve 100 is provided with an identification mechanism 6 .

[0098] The marking mechanism 6 can be a length scale provided on the detection portion 11-12 at the distal end of the outlet 11-1, so that the detection portion 11-12 functions as a probe, and the depth of the periodontal pocket can be visually read through the observation mirror 200. The marking mechanism 6 can also be an angle scale provided on the adjustment mechanism 3, so that the adjustment angle of the observation position 11-11 can be identified by observing the rotation angle of the adjustment mechanism 3.

[0099] Referring to Figure 8, during clinical use, the observation mirror 200 is inserted into the working channel 11 of the sleeve 1 through the inlet 11-2, the distal end of the sleeve 1 is inserted into the periodontal pocket, and the observation mirror 200 is extended from the outlet 11-1 to observe the tooth side. When the observation direction needs to be adjusted, the adjustment mechanism 3 is rotated to adjust the observation direction of the observation position 11-11 as needed.

[0100] In this embodiment, since the adjustment mechanism 3 can adjust the observation direction of the observation position 11-11, the holding portion 2 only needs to be placed at a suitable position at the corner of the mouth during use, and does not need to be adjusted according to the observation angle. When the observation angle needs to be adjusted, the adjustment mechanism 3 is adjusted to adjust the observation direction of the observation position 11-11, thereby ensuring that the observation mirror 200 is always facing the side surface of the tooth for effective observation. The placement position of the holding portion 2 does not need to be adjusted during clinical use, and certain parts will not be unable to be effectively observed due to the limitation of the holding portion 2. Observation of all directions of the periodontium can be achieved during clinical use, and the applicability is very wide.

[0101] Example 2: Adjustable periodontal endoscope sleeve of the present invention with a bidirectional ratchet adjustment mechanism

[0102] 3 to 4 - 5 , the difference between this embodiment and embodiment 1 is that, in this embodiment, the adjustment mechanism 3 is a bidirectional ratchet adjustment mechanism 301 - 2 .

[0103] 3-4 and 4-4, the positioning groove 31-11 of the ratchet 31-1 is a symmetrical positioning groove 31-11-2, the pawl mechanism 32-1 is a symmetrical positioning block 32-12, and the symmetrical positioning groove 31-11-2 and the symmetrical positioning block 32-12 together constitute the bidirectional ratchet adjustment mechanism 301-2.

[0104] Referring to Figures 3 and 3-4, the pawl mechanism 32-1 can be an integral structure arranged on the inner side of the outer sleeve 32 to better ensure the positioning effect; it can also be a local structure arranged on the inner side of the outer sleeve 32 to reduce the movement resistance while ensuring the positioning effect, referring to Figures 4 and 4-4.

[0105] In this embodiment, since the adjustment mechanism 3 adopts a symmetrical structure, it can freely rotate in both directions during use, making the use process more convenient.

[0106] Example 3: Adjustable periodontal endoscope sleeve of the present invention with an interference fit adjustment mechanism

[0107] 5 to 5 - 5 , the difference between this embodiment and embodiment 1 is that, in this embodiment, the adjustment mechanism 3 is an interference fit adjustment mechanism 302 .

[0108] Referring to Figures 5-2 and 5-3, the inner tube mechanism 31 is arranged at the proximal end of the sleeve 1 and is made of elastic material. The outer tube mechanism 32 is arranged at the proximal end of the gripping portion 2. Hold the gripping portion 2 and rotate the inner tube mechanism 31. The inner tube mechanism 31 overcomes the friction force of the outer tube mechanism 32 and rotates, and the sleeve 1 rotates accordingly to the required direction and stops rotating. Under the action of friction, the inner tube mechanism 31 is fixed, and the direction of the observation position 11-11 is adjusted and determined accordingly.

[0109] In this embodiment, the interference fit rotation adjustment method realizes positioning through the friction between the inner tube mechanism 31 and the outer tube mechanism 32. Since there is no positioning convex step, the direction of the observation position 11-11 can be adjusted steplessly. The direction of the observation position 11-11 can be adjusted to any angle as needed, which is very convenient for clinical use. Refer to Figures 5 and 5-5.

[0110] Referring to Figure 5-4, in order to avoid the friction of the entire plane between the inner tube mechanism 31 and the outer tube mechanism 32, which causes difficulty in rotation due to friction force, a friction block 32-3 can be set on the outer tube mechanism 32. The size of the friction force can be adjusted by setting the size of the contact area between the friction block 32-3 and the inner tube mechanism 31, thereby ensuring that the friction force can achieve positioning between the inner tube mechanism 31 and the outer tube mechanism 32, and will not be too large to cause difficulty in rotation.

[0111] Example 4: Adjustable periodontal endoscope of the present invention

[0112] 9 , in this embodiment, the adjustable periodontal endoscope 900 includes the observation lens 200 and the adjustable periodontal endoscope sleeve 100 described in the previous embodiment.

[0113] The observation mirror 200 and the adjustable periodontal endoscope cover 100 can be manufactured into an integral body to form the adjustable periodontal endoscope 900 .

[0114] In this embodiment, the observation scope 200 is a fiber-optic observation scope 201. The handle 2 includes a housing 21, which houses a light source 22 and a circuit system 23. The light source 22 provides illumination for the fiber-optic observation scope 201, and the circuit system 23 connects the observation scope 200 to a main unit 202 of the observation scope 200. The distal end of the observation scope 200 is disposed within the sleeve 1, and the adjustable periodontal endoscope sleeve 100 adjusts the viewing direction of the observation position 11-11 to ensure that the observation scope 200 can observe the tooth side effectively. For miniature periodontal endoscopes, such as those with a diameter of 1 mm or less, the illumination method of the observation scope 200 is typically fiber-optic illumination. In the present invention, this type of endoscope employing fiber-optic illumination is referred to as the fiber-optic observation scope 201. Because optical fibers are easily broken and require side shielding during use, the light source is typically located close to the observation end, such as within the housing 21 of the handle 2. The circuit system 23 is connected to the host 202 and provides power to the light source 22 . The light source 22 provides illumination to the observation scope 200 through light-guiding optical fibers to ensure the normal operation of the observation scope 200 .

[0115] In this embodiment, the adjustable periodontal endoscope 900 includes the adjustable periodontal endoscope cover 100. During use, the direction of the observation position 11-11 can be adjusted via the adjustment mechanism 3 without adjusting the position and direction of the grip 2. Therefore, during clinical use, observation of the periodontium from all directions can be achieved without moving the grip 2, providing a wide range of applications.
