Description

TECHNICAL FIELD

[0001] The present application relates to an auxiliary instrument for oral treatment, in particular an adjustable periodontal endoscope sleeve and an adjustable periodontal endoscope used in cooperation with a periodontal endoscope. BACKGROUND

[0002] Periodontal disease, especially periodontitis, is the most common disease in current oral diseases. If not treated in time, symptoms such as gum bleeding, periodontal pocket, abscess, and tooth loosening may occur as the disease progresses. The main pathogenic factors of periodontitis are dental calculus and dental plaque formed on the surface of the tooth root.

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

[0004] The current treatment process is to use a fine subgingival scaler to remove the root surface lesions and scattered dental calculus and dental plaque around the tooth root according to the reflection of the mouth mirror and the feel, so that the root surface is smooth. During or after scaling, a sharp probe must be used to carefully probe whether the subgingival calculus is completely removed and whether the root surface is smooth to determine the scaling effect.

[0005] Since scaling is performed only by the reflection of the mouth mirror and the feel, the scaling situation in the periodontal pocket cannot be well observed, so tissue damage or incomplete scaling may easily occur. To avoid this situation, periodontal endoscopes are currently used to assist in the subgingival scaling process.

[0006] The current periodontal endoscope usually has a sleeve, and the outlet end of the sleeve is a conical slope facing the tooth side. The endoscope extends from the outlet of the sleeve and observes toward the tooth side.

[0007] The structure and angle between the conical slope of the outlet of the current sleeve and the handle are fixed, so during observation, the conical slope may not be well directed toward the tooth side due to the limitation of the handle, thereby affecting the observation effect. Therefore, the current sleeve needs to be improved for better clinical use. SUMMARY

[0008] The adjustable periodontal endoscope sleeve of the present application can adjust the direction of the conical slope at the outlet of the sleeve through the adjusting mechanism arranged on the sleeve, thereby solving the problem that the conical slope at the outlet of the sleeve cannot be directed toward the tooth side due to the limitation of the handle in current clinical use, and the application has a wider range of clinical use.

[0009] The adjustable periodontal endoscope sleeve of the present application is characterized in that: the adjustable periodontal endoscope sleeve 100 comprises a sleeve 1, a holding part 2 and an adjusting mechanism 3;

[0010] A. The sleeve 1 comprises a working channel 11, and an observation site 11-11 is arranged at the outlet 11-1 of the working channel 11;

[0011] B. The proximal end of the sleeve 1 is connected with the holding part 2;

[0012] C. The adjusting mechanism 3 is connected with the sleeve 1, and the observation direction of the observation site 11-11 of the sleeve 1 changes when the adjusting mechanism 3 is adjusted;

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

[0014] Since the adjusting mechanism 3 can adjust the observation direction of the observation site 11-11, the holding part 2 only needs to be placed at a suitable position of the mouth corner during use, and does not need to be adjusted according to the observation angle. When the observation angle needs to be adjusted, the adjusting mechanism 3 is adjusted, and the observation direction of the observation site 11-11 is adjusted, so that the observation mirror 200 can always be effectively observed towards the dental side. The placement position of the holding part 2 does not need to be adjusted in clinical use, and some parts cannot be effectively observed due to the limitation of the holding part 2. The observation of each direction of the periodontal can be realized in clinical use, and the application range is very wide.

[0015] The distal end of the outlet 11-1 is provided with a detection part 11-12. The detection part 11-12 is usually made into a probe-shaped member with a smooth tip, which can be deeply inserted into the periodontal pocket for detection, better expose the operation field of view during treatment, and realize better operation observation.

[0016] The adjusting mechanism 3 adjusts the direction of the observation site 11-11 of the outlet 11-1 in a rotating manner. The rotating adjustment mode can realize 360° rotation adjustment, which is not only simple to operate, but also has a large adjustment range. The rotating adjustment mode can be realized by various specific structures such as the interference fit rotation of the inner and outer sleeves, the ratchet rotation, the screw rotation, etc.

[0017] The adjusting mechanism 3 comprises an inner tube mechanism 31 and a sleeve mechanism 32, the sleeve mechanism 32 is sleeved outside the inner tube mechanism 31, and the relative rotation between the inner tube mechanism 31 and the sleeve mechanism 32 adjusts the direction of the observation position 11-11 of the outlet 11-1. The sleeve structure of the inner tube mechanism 31 and the sleeve mechanism 32 can adjust the direction of the observation position 11-11 through the relative movement of the inner sleeve and the outer sleeve, which is convenient to operate and has a simple structure.

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

[0019] The inner tube mechanism 31 is arranged at the proximal end of the sleeve 1, and the outer part is provided with a ratchet 31-1; the sleeve mechanism 32 is arranged at the proximal end of the holding part 2, and the inner side is provided with a pawl mechanism 32-1; the ratchet 31-1 is provided with at least two positioning grooves 31-11, and the ratchet 31-1 is rotated, the pawl mechanism 32-1 is separated from the positioning grooves 31-11, the sleeve 1 is rotated, and the pawl mechanism 32-1 is embedded in the positioning grooves 31-11 of the ratchet 31-1 to form positioning, and the direction of the observation position 11-11 is adjusted and determined. The ratchet adjusting mode can not only be rotated very conveniently, but also can set the size of the ratchet according to the required adjustment accuracy, can be adjusted according to the set adjustment angle, and the ratchet structure has good positioning effect, which can effectively fix the observation direction of the observation position 11-11.

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

[0021] The positioning grooves 31-11 of the ratchet 31-1 are asymmetric positioning grooves 31-11-1, the pawl mechanism 32-1 is an asymmetric positioning block 32-11, and the asymmetric positioning grooves 31-11-1 and the asymmetric positioning block 32-11 jointly constitute the one-way ratchet adjusting mechanism 301-1. The asymmetric one-way structure can prevent misrotation and ensure the adjustment direction of the angle.

[0022] The ratchet adjusting mechanism 301 is a two-way ratchet adjusting mechanism 301-2.

[0023] The positioning grooves 31-11 of the ratchet 31-1 are symmetric positioning grooves 31-11-2, the pawl mechanism 32-1 is a symmetric positioning block 32-12, and the symmetric positioning grooves 31-11-2 and the symmetric positioning block 32-12 jointly constitute the two-way ratchet adjusting mechanism 301-2. The symmetric structure can freely rotate in two directions during use, which is very convenient to use.

[0024] The adjusting mechanism 3 is an interference fit adjusting 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 sleeve mechanism 32 is arranged at the proximal end of the holding part 2 and holds the holding part 2. When the inner tube mechanism 31 is rotated, the inner tube mechanism 31 overcomes the friction of the outer sleeve mechanism 32 and rotates, and the sleeve 1 rotates to the desired direction and stops rotating. Under the action of friction, the inner tube mechanism 31 is fixed, and the direction of the observation site 11-11 is adjusted and determined.

[0026] The interference fit rotation adjusting mode realizes positioning through the friction between the inner tube mechanism 31 and the outer sleeve mechanism 32. Since there is no positioning convex step, the direction of the observation site 11-11 can be adjusted steplessly, and the direction of the observation site 11-11 can be adjusted to any angle as needed, which is very convenient for clinical use. In order to avoid the whole plane friction between the inner tube mechanism 31 and the outer sleeve mechanism 32 causing difficulty in rotating, a friction block 32-3 can be arranged on the outer sleeve mechanism 32. The size of the friction block 32-3 and the inner tube mechanism 31 is adjusted to adjust the size of the friction, so as to ensure that the friction can realize the positioning between the inner tube mechanism 31 and the outer sleeve mechanism 32, and will not be too large to cause difficulty in rotating.

[0027] The adjustable periodontal endoscope sleeve 100 is also provided with an axial movement limiting mechanism 4. Since the sleeve 1 needs to be inserted into the periodontal pocket and kept at the deep part of the periodontal pocket during use to ensure that the observation mirror 200 can observe the tooth side in the periodontal pocket, the sleeve 1 is in a stressed state during use. Therefore, it is necessary to ensure that the sleeve 1 will not move axially up and down. The axial movement limiting mechanism 4 can limit the axial movement of the sleeve 1 to prevent the sleeve 1 from moving up during use, so that the observation mirror 200 moves up and cannot observe the periodontal pocket.

[0028] The inner tube mechanism 31 of the adjusting mechanism 3 is provided with an axial limiting groove 31-2 to constitute the axial movement limiting mechanism 4. The outer sleeve mechanism 32 is embedded in the axial limiting groove 31-2. When the holding part 2 is held, the sleeve 1 cannot move axially. The outer sleeve mechanism 32 and the holding part 2 are fixedly connected. When embedded in the axial limiting groove 31-2, since the holding part 2 is held in the hand of the user, the sleeve 1 is also limited from moving. This concave-convex clamping embedding mode realizes simple structure through the limiting action of the axial limiting groove 31-2.

[0029] The angle β between the holding part 2 and the sleeve 1 is adjusted by the angle adjusting mechanism 5. The angle β can be adjusted by the angle adjusting mechanism 5 as needed, so as to adapt to different periodontal and tooth shapes and angles.

[0030] The angle adjusting mechanism 5 is a shaping mechanism 51 arranged at the distal end of the holding part 2.

[0031] The shaping mechanism 51 is integrally manufactured from a shaping material. Generally, the shaping mechanism 51 is made of a shapeable metal, which not only guarantees the shaping effect but also has good strength and maintains stability during use. This integrally manufactured manner of the shaping material can make the structure of the holding part 2 still simple, and the adjustment during the clinical process is very convenient.

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

[0033] The identification mechanism 6 is arranged on the detection part 11-12 at the distal end of the outlet 11-1 and / or on the adjusting mechanism 3. The identification mechanism 6 can be a length scale arranged on the detection part 11-12 at the distal end of the outlet 11-1, so that the detection part 11-12 becomes a probe, and the depth of the periodontal pocket can be directly read through the observation mirror 200. The identification mechanism 6 can also be an angle scale arranged on the adjusting mechanism 3, and the adjustment angle of the direction of the observation site 11-11 can be identified by observing the rotation angle of the adjusting mechanism 3.

[0034] The distal end of the sleeve 1 is in a conical structure. This conical structure can make the distal end of the sleeve 1 conveniently explore into the deep part of the periodontal pocket.

[0035] The inlet 11-2 of the working channel 11 is in a trumpet shape. The trumpet-shaped inlet shape makes it more convenient to insert the observation mirror 200 into the sleeve 1.

[0036] In 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 explored into the periodontal pocket, the observation mirror 200 is explored out of the outlet 11-1, and the tooth side is observed. When it is necessary to adjust the observation direction, the adjusting mechanism 3 is rotated, and the observation direction of the observation site 11-11 can be adjusted as needed.

[0037] The adjustable periodontal endoscope of the present application is characterized in that: the adjustable periodontal endoscope 900 comprises the observation mirror 200 and the adjustable periodontal endoscope sleeve 100. The observation mirror 200 and the adjustable periodontal endoscope sleeve 100 can be integrally manufactured to form the adjustable periodontal endoscope 900.

[0038] The observation mirror 200 is a fiber type observation mirror 201; the holding part 2 contains a shell 21, the shell 21 is provided with a light source 22 and a circuit system 23, the light source 22 provides illumination for the fiber type observation mirror 201, the circuit system 23 connects the observation mirror 200 and the host computer 202 of the observation mirror 200; the distal end of the observation mirror 200 is arranged in the sleeve 1, the adjustable periodontal endoscope sleeve 100 adjusts the observation direction of the observation site 11-11, so as to ensure the observation effect of the observation mirror 200 on the tooth side. For the miniature periodontal endoscope, such as the periodontal endoscope with a diameter of less than 1mm, the illumination mode of the observation mirror 200 is usually fiber illumination, and the endoscope mode using fiber illumination in the application is referred to as the fiber type observation mirror 201. Because the fiber is easy to break and the side needs to be shaded during use, the light source is usually arranged close to the observation end, such as the shell 21 of the holding part 2. The host computer 202 is connected through the circuit system 23 and provides power for the light source 22, the light source 22 provides illumination for the observation mirror 200 through the light guide fiber, and ensures the normal work of the observation mirror 200.

[0039] The adjustable periodontal endoscope 900 contains the adjustable periodontal endoscope sleeve 100, and the direction of the observation site 11-11 can be adjusted through the adjusting mechanism 3 during use, without the need to adjust the position and direction of the holding part 2. Therefore, the observation in each direction of the periodontal can be realized without moving the holding part 2 during clinical use, and the application range is very wide.

[0040] The adjustable periodontal endoscope sleeve contains a sleeve 1, a holding part 2 and an adjusting mechanism 3. The sleeve 1 contains a working channel 11, and the outlet 11-1 of the working channel 11 is provided with an observation site 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 site 11-11 through the outlet 11-1 of the working channel 11. The adjusting mechanism 3 is connected with the sleeve 1, and the observation direction of the observation site 11-11 of the sleeve 1 changes when the adjusting mechanism 3 is adjusted. During use, the position and direction of the holding part 2 do not need to be adjusted, when the observation angle needs to be adjusted, the adjusting mechanism 3 is adjusted, the observation direction of the observation site 11-11 is adjusted, so that the observation mirror 200 can always be effectively observed towards the tooth side, the observation in each direction of the periodontal can be realized, and the application range is very wide. The adjustable periodontal endoscope can realize the observation in each direction of the periodontal without moving the holding part 2 during clinical use, and the use is very convenient, because the adjustable periodontal endoscope sleeve is arranged.

[0086] Example 1: The adjustable periodontal endoscope sleeve of the present application containing a one-way ratchet adjusting mechanism

[0087] Reference​​Figures 1 to 2-5 In this embodiment, the adjustable periodontal endoscope sleeve 100 includes a sleeve 1, a grip 2, and an adjustment mechanism 3.

[0088] refer to Figure 1-2 , Figure 1-3 , Figure 2-2 and Figure 2-3 The cannula 1 includes a working channel 11, and the outlet 11-1 of the working channel 11 is provided with an observation position 11-11. A probe part 11-12 is provided at the distal end of the outlet 11-1. The probe part 11-12 is typically made into a probe-like component with a smooth tip, which can penetrate deep into the periodontal pocket for probing, better exposing the operational field of view during treatment, and achieving better operational observation. The inlet 11-2 of the working channel 11 is funnel-shaped, which makes it easier to insert the observation mirror 200 into the cannula 1.

[0089] refer to Figure 1 and Figure 2 The distal end of the cannula 1 has a conical structure. This conical structure allows the distal end of the cannula 1 to easily penetrate deep into the periodontal pocket.

[0090] The adjustment mechanism 3 is connected to the sleeve 1. Adjusting the adjustment mechanism 3 changes the observation direction of the observation position 11-11 of the sleeve 1.

[0091] In this embodiment, the adjustment mechanism 3 adjusts the direction of the observation position 11-11 of the outlet 11-1 by rotation. Rotation adjustment allows for 360° rotation, which is not only simple to operate but also has a large adjustment range. Rotation adjustment can be achieved through various specific structures such as interference fit rotation of the inner and outer sleeves, ratchet rotation, and threaded rotation.

[0092] refer to Figure 1-4 and Figure 2-4 The adjusting mechanism 3 includes an inner tube mechanism 31 and an outer tube mechanism 32. The outer tube mechanism 32 is sleeved on the outside of the inner tube mechanism 31. The inner tube mechanism 31 and the outer tube mechanism 32 rotate relative to each other, thereby adjusting the direction of the observation position 11-11 of the outlet 11-1. This inner-outer-outer structure of the inner tube mechanism 31 and the outer tube mechanism 32 allows for adjustment of the direction of the observation position 11-11 through simple relative movement of the inner and outer tubes, making it not only convenient to operate but also very simple in structure.

[0093] In this embodiment, the adjustment mechanism 3 is a ratchet adjustment mechanism 301.

[0094] refer to Figure 1-4 and Figure 2-4The inner tube mechanism 31 is arranged at the proximal end of the sleeve 1, and the outer side is provided with a ratchet wheel 31-1; the outer sleeve mechanism 32 is arranged at the proximal end of the holding part 2, and the inner side is provided with a pawl mechanism 32-1; the ratchet wheel 31-1 is provided with at least two positioning grooves 31-11, and the pawl mechanism 32-1 is disengaged from the positioning groove 31-11 when the ratchet wheel 31-1 is rotated, and the sleeve 1 is rotated, and after rotating to the position to be adjusted, the pawl mechanism 32-1 is embedded in the positioning groove 31-11 of the ratchet wheel 31-1 to form positioning, and the direction of the observation site 11-11 is adjusted and determined. This ratchet type adjusting mode can not only be very convenient to rotate, but also can set the size of the ratchet according to the required adjustment accuracy, and can conveniently adjust according to the set adjustment angle, and the ratchet structure has good positioning effect, which can effectively fix the observation direction of the observation site 11-11.

[0095] Referring to Figure 1-4 and Figure 2-4 In this embodiment, the ratchet adjusting mechanism 301 is a one-way ratchet adjusting mechanism 301-1.

[0096] The positioning groove 31-11 of the ratchet wheel 31-1 is an asymmetric positioning groove 31-11-1, and the pawl mechanism 32-1 is an asymmetric positioning block 32-11, and the asymmetric positioning groove 31-11-1 and the asymmetric positioning block 32-11 together constitute the one-way ratchet adjusting mechanism 301-1. This asymmetric one-way structure can prevent misrotation and ensure the adjustment direction of the angle.

[0097] Referring to Figure 1-4 and Figure 2-4 In order to ensure the movement space of the ratchet wheel 31-1 during rotation, the outer sleeve mechanism 32 is provided with a deformation groove 32-2.

[0098] Referring to Figure 1 and Figure 1-4 The pawl mechanism 32-1 can be a whole structure arranged on the inner side of the outer sleeve 32 to better ensure the positioning effect; or it can be a partial structure arranged on the inner side of the outer sleeve 32, which can ensure the positioning effect while reducing the movement resistance, referring to Figure 2 and Figure 2-4 .

[0099] Referring to Figure 1-2 and Figure 2-2In this embodiment, the sleeve mechanism 32 is integrally manufactured with the holding portion 2. The inner tube mechanism 31 is provided with an axial limiting groove 31-2 constituting an axial movement limiting mechanism 4, and the sleeve mechanism 32 is embedded in the axial limiting groove 31-2. When holding the holding portion 2, the sleeve 1 cannot move axially. Since the sleeve mechanism 32 is fixedly connected with the holding portion 2, when embedded in the axial limiting groove 31-2, the sleeve 1 is also limited from moving because the holding portion 2 is held in the hand of the user. This concave-convex clamping embedding method is very simple in structure through the limiting effect of the axial limiting groove 31-2.

[0100] Since the adjustable periodontal endoscope sleeve 100 needs to be inserted into the periodontal pocket and kept at the deep part of the periodontal pocket during use to ensure that the observation mirror 200 can observe the tooth side in the periodontal pocket, the sleeve 1 is in a stressed state during use, and therefore the axial upward and downward displacement of the sleeve 1 needs to be prevented. The axial movement limiting mechanism 4 can limit the axial movement of the sleeve 1 to prevent the sleeve 1 from moving upward during use, so that the observation mirror 200 moves upward and cannot observe the periodontal pocket.

[0101] Reference Figures 6 to 6-2 In this embodiment, the angle β between the holding portion 2 and the sleeve 1 can also be adjusted by an angle adjusting mechanism 5. The angle β can be adjusted by the angle adjusting mechanism 5 as needed to adapt to different periodontal and tooth shapes and angles.

[0102] The angle adjusting mechanism 5 is a shaping mechanism 51 provided at the distal end of the holding portion 2. Reference Figure 6-1 In this embodiment, the shaping mechanism 51 and the holding portion 2 are connected and installed together by threads.

[0103] The shaping mechanism 51 is integrally manufactured from a shaping material. Generally, the shaping mechanism 51 is made of a shapeable metal, which not only ensures the shaping effect but also has good strength to maintain stability during use. This integrally manufactured method of the shaping mechanism 51 can make the structure of the holding portion 2 still very simple, and the adjustment is very convenient during clinical procedures.

[0104] Reference Figure 7 And Figure 7-1 In this embodiment, a detection portion 11-12 is provided at the distal end of the outlet 11-1 and on the adjusting mechanism 3. The adjustable periodontal endoscope sleeve 100 is provided with an identification mechanism 6.

[0105] The identification mechanism 6 can be a length scale arranged on the detection part 11-12 at the distal end of the outlet 11-1, so that the detection part 11-12 becomes a probe, and the depth of the periodontal pocket can be directly read through the observation mirror 200. The identification mechanism 6 can also be an angle scale arranged on the adjusting mechanism 3, and the adjusting angle of the direction of the observation site 11-11 can be identified by observing the rotating angle of the adjusting mechanism 3.

[0106] Reference Figure 8 In 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, the observation mirror 200 is exposed from the outlet 11-1, and the dental side is observed. When it is necessary to adjust the observation direction, the adjusting mechanism 3 is rotated, and the observation direction of the observation site 11-11 can be adjusted as needed.

[0107] In this embodiment, since the adjusting mechanism 3 can adjust the observation direction of the observation site 11-11, the holding part 2 only needs to be placed at a suitable position of the mouth during use, and does not need to be adjusted according to the observation angle. When it is necessary to adjust the observation angle, the adjusting mechanism 3 is adjusted, the observation direction of the observation site 11-11 is adjusted, so that the observation mirror 200 can always effectively observe the dental side, the placement position of the holding part 2 does not need to be adjusted in clinical use, and some parts cannot be effectively observed due to the limitation of the holding part 2. In clinical use, the observation of each direction of the periodontal pocket can be realized, and the application range is very wide.

[0108] Embodiment 2: The adjustable periodontal endoscope sleeve of the application comprising a bidirectional ratchet adjusting mechanism

[0109] Reference Figures 3 to 4-5 The difference between this embodiment and embodiment 1 is that, in this embodiment, the adjusting mechanism 3 is a bidirectional ratchet adjusting mechanism 301-2.

[0110] Reference Figure 3-4 And Figure 4-4 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 jointly constitute the bidirectional ratchet adjusting mechanism 301-2.

[0111] Reference Figure 3 And Figure 3-4 The pawl mechanism 32-1 can be a whole structure arranged inside the outer sleeve 32, so as to better ensure the positioning effect; or can be a partial structure arranged inside the outer sleeve 32, so as to reduce the movement resistance while ensuring the positioning effect.Figure 4 and Figure 4-4 .

[0112] In this embodiment, the adjustment mechanism 3 adopts a symmetrical structure, which can be freely rotated in both directions during use, making the use more convenient.

[0113] Embodiment 3: adjustable periodontal endoscope sleeve of the present application containing interference fit adjustment mechanism

[0114] Referring to Figures 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.

[0115] Referring to Figure 5-2 and Figure 5-3 , the inner tube mechanism 31 is arranged at the proximal end of the sleeve 1 and is made of elastic material, and the outer sleeve mechanism 32 is arranged at the proximal end of the holding part 2. Hold the holding part 2, rotate the inner tube mechanism 31, the inner tube mechanism 31 overcomes the friction of the outer sleeve mechanism 32 and rotates, the sleeve 1 rotates to the required direction, stops rotating, and the inner tube mechanism 31 is fixed under the action of friction, the direction of the observation site 11-11 is adjusted and determined.

[0116] In this embodiment, the interference fit rotation adjustment method realizes positioning through the friction between the inner tube mechanism 31 and the outer sleeve mechanism 32. Since there is no positioning convex step, the stepless adjustment of the direction of the observation site 11-11 can be realized, and the direction of the observation site 11-11 can be adjusted to any angle as needed, which is very convenient for clinical use. Referring to Figure 5 and Figure 5-5 .

[0117] Referring to Figure 5-4 , in order to avoid the whole plane friction between the inner tube mechanism 31 and the outer sleeve mechanism 32 leading to difficult rotation, a friction block 32-3 can be arranged on the outer sleeve mechanism 32. The size of the friction force is adjusted by adjusting the contact area between the friction block 32-3 and the inner tube mechanism 31, so as to ensure that the friction force can realize the positioning between the inner tube mechanism 31 and the outer sleeve mechanism 32, and will not be too large to cause difficult rotation.

[0118] Embodiment 4: adjustable periodontal endoscope of the present application

For a miniature periodontal endoscope, such as a periodontal endoscope with a diameter of less than 1 mm, the illumination mode of the observation mirror 200 is usually fiber illumination, and the endoscope mode using fiber illumination in the application is referred to as the fiber type observation mirror 201. Since the fiber is easy to break and the side needs to be shaded during use, the light source is usually arranged close to the observation end, such as the shell 21 of the holding part 2. The main machine 202 is connected through the circuit system 23 and provides power for the light source 22, the light source 22 provides illumination for the observation mirror 200 through the light guide fiber, and ensures the normal work of the observation mirror 200.

[0122] In the embodiment, the adjustable periodontal endoscope 900 comprises the adjustable periodontal endoscope sleeve 100, and the direction of the observation position 11-11 can be adjusted through the adjusting mechanism 3 during use, without the need to adjust the position and direction of the holding part 2. Therefore, during clinical use, the observation of various directions of the periodontal can be realized without moving the holding part 2, and the application range is very wide.
