Description

Technical Field

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

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

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

[0004] The usual treatment process at present 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 to make the root surface smooth. During or after the scaling operation, a sharp probe must be used to carefully check whether the subgingival tartar has been scraped away cleanly and whether the root surface is smooth to determine the effectiveness of the scaling.

[0005] Since the scraping is done only by the reflection of the mouth mirror and the feel of the hand, it is impossible to observe the scraping condition in the periodontal pocket well, so it is very easy to cause tissue damage or incomplete scraping. To avoid this situation, periodontal endoscopes are now used to assist the subgingival scraping process.

[0006] Current periodontal endoscopes are usually provided with a lens sleeve, the outlet end of which is a conical slope facing the tooth side, and the endoscope extends from the outlet of the lens sleeve to observe the tooth side.

[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 to the tooth side due to the limitation of the handle, thus 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 lens cover of the utility model can adjust the direction of the cone surface at the outlet of the lens cover through the adjustment mechanism arranged on the lens cover, thereby solving the problem that the cone surface at the outlet of the lens cover cannot be oriented toward the tooth side due to the limitation of the handle in current clinical use, and has a wider application range in clinical use.

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

[0010] A. The sleeve 1 comprises 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 sleeve 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 entrance 11 - 2 of the working channel 11 , and observes the tissue at the observation position 11 - 11 through the exit 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 tooth side 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 detection part 11-12. The detection part 11-12 is usually made into a probe-shaped 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. The rotation adjustment method can achieve 360° rotation adjustment, which is not only simple to operate but also has a large adjustment range. The rotation adjustment method can be achieved by 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, wherein the outer tube mechanism 32 is sleeved on the outer side of the inner tube mechanism 31, and a relative rotational motion occurs between the inner tube mechanism 31 and the outer tube mechanism 32 to adjust the direction of the observation position 11-11 of the outlet 11-1. The inner tube mechanism 31 and the outer tube mechanism 32 are arranged inside and outside, and the direction of the observation position 11-11 can be adjusted by a simple relative motion 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 arranged 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 arranged on the inside; at least two positioning grooves 31-11 are arranged on the ratchet 31-1, and the ratchet 31-1 is rotated, and the pawl mechanism 32-1 is disengaged 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 can not only rotate very conveniently, but also set the size of the ratchet according to the required adjustment accuracy, and can be conveniently adjusted according to the set adjustment angle, and 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 ratchet 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 erroneous rotation and ensure the adjustment direction of the angle.

[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, 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. The symmetrical structure can freely rotate in both directions during use, which is 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 holding part 2. The holding part 2 is held and the inner tube mechanism 31 is rotated. 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 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. In order to avoid the friction of the entire plane between the inner tube mechanism 31 and the outer tube mechanism 32 causing difficulty in rotation due to friction, a friction block 32-3 can be set 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 both realize the positioning between the inner tube mechanism 31 and the outer tube mechanism 32 and will not be too large to cause difficulty in rotation.

[0027] The adjustable periodontal endoscope cover 100 is also provided with an axial movement limiting mechanism 4. Since the sleeve 1 needs to be inserted into the periodontal pocket and remain deep in the periodontal pocket during use of the adjustable periodontal endoscope cover 100 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, so it is necessary to ensure that the sleeve 1 does not shift up and down axially. 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, thereby causing the observation mirror 200 to move up and fail to observe the periodontal pocket.

[0028] The inner tube mechanism 31 of the adjustment mechanism 3 is provided with an axial limit groove 31-2 to constitute the axial movement limiting mechanism 4, and 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. 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 matching and embedding method is very simple in structure through the limiting effect of the axial limit groove 31-2.

[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 disposed at the distal end of the gripping portion 2 .

[0031] The shaping mechanism 51 is made of a shaping material as a whole. Usually, the shaping mechanism 51 is made of a plastic metal, which not only ensures the shaping effect but also has good strength and maintains stability during use. This method of manufacturing the whole body of the shaping material can make the structure of the grip 2 still very simple, and it is very convenient to adjust during clinical procedures.

[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 adjustment 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 read intuitively through the observation mirror 200. The identification mechanism 6 can also be an angle scale arranged on the adjustment mechanism 3, and the adjustment angle of the direction of the observation position 11-11 can 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 into the depth of the periodontal pocket.

[0035] The inlet 11 - 2 of the working channel 11 is in a trumpet shape, which makes it more convenient for the observation scope 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, and the distal end of the sleeve 1 is inserted into the periodontal pocket. 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 mirror 200 and the adjustable periodontal endoscope cover 100. The observation mirror 200 and the adjustable periodontal endoscope cover 100 can be manufactured as a whole to form the adjustable periodontal endoscope 900.

[0038] The observation mirror 200 is a fiber-optic observation mirror 201; the gripping part 2 includes a shell 21, and a light source 22 and a circuit system 23 are arranged in the shell 21. The light source 22 provides illumination for the fiber-optic observation mirror 201, and the circuit system 23 connects the observation mirror 200 with the host 202 of the observation mirror 200; the distal end of the observation mirror 200 is arranged in the sleeve 1, and the adjustable periodontal endoscope sleeve 100 adjusts the observation direction of the observation position 11-11 to ensure the observation effect of the observation mirror 200 on the tooth side. For a micro periodontal endoscope, such as a periodontal endoscope with a diameter of less than 1 mm, the illumination method of the observation mirror 200 is usually optical fiber illumination. In the present utility model, this endoscope method using optical fiber illumination is referred to as the fiber-optic observation mirror 201. Since the optical fiber is easy to break and the side needs to be shielded during use, the light source is usually arranged at a position close to the observation end, such as usually arranged in the shell 21 of the gripping part 2. The circuit system 23 is connected to the host 202 and provides power to the light source 22 . The light source 22 provides lighting to the observation scope 200 through light-guiding optical fibers to ensure the normal operation of the observation scope 200 .

[0039] Since the adjustable periodontal endoscope 900 includes the adjustable periodontal endoscope cover 100, the direction of the observation position 11-11 can be adjusted by the adjustment mechanism 3 during use without adjusting the position and direction of the gripping portion 2. Therefore, during clinical use, observation of the periodontium in all directions can be achieved without moving the gripping portion 2, and the application range is very wide.

[0040] The adjustable periodontal endoscope sleeve of the utility model comprises a sleeve 1, a gripping portion 2 and an adjusting mechanism 3. The sleeve 1 comprises a working channel 11, and an 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 to adjust the observation direction of the observation position 11-11, so as to ensure that the observation mirror 200 always faces the tooth side surface 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, and the use is very convenient.

[0086] Embodiment 1: Adjustable periodontal endoscope sleeve of the present invention with a one-way ratchet adjustment mechanism

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

[0088] refer to Figure 1-2 , Figure 1-3 , Figure 2-2 and Figure 2-3 The sleeve 1 includes a working channel 11, and an outlet 11-1 of the working channel 11 is provided with an observation position 11-11. A detection part 11-12 is provided at the distal end of the outlet 11-1. The detection part 11-12 is usually made into a probe-shaped 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. The entrance 11-2 of the working channel 11 is trumpet-shaped, and the trumpet-shaped entrance shape makes it more convenient for the observation mirror 200 to be inserted into the sleeve 1.

[0089] refer to Figure 1 and Figure 2 The distal end of the sleeve 1 is in a conical structure, which enables the distal end of the sleeve 1 to easily penetrate into the depth of the periodontal pocket.

[0090] 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 .

[0091] In this embodiment, the adjustment mechanism 3 adjusts the direction of the observation position 11-11 of the outlet 11-1 by rotation. The rotation adjustment method can achieve 360° rotation adjustment, which is not only simple to operate but also has a large adjustment range. The rotation 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.

[0092] refer to Figure 1-4 and Figure 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. The inner tube mechanism 31 and the outer tube mechanism 32 are arranged inside and outside, and the direction of the observation position 11-11 can be adjusted by simply moving the inner and outer sleeves relative to each other. This is 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 a ratchet 31-1 is arranged on the outside; the outer tube mechanism 32 is arranged at the proximal end of the gripping portion 2, and a ratchet mechanism 32-1 is arranged on the inside; at least two positioning grooves 31-11 are arranged on the ratchet 31-1, and the ratchet mechanism 32-1 is disengaged from the positioning groove 31-11 when the ratchet 31-1 is rotated, and the sleeve 1 rotates accordingly. After rotating to the position to be adjusted, the ratchet 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 can not only rotate very conveniently, but also set the size of the ratchet according to the required adjustment accuracy, and can be easily adjusted according to the set adjustment angle, and the ratchet structure has a good positioning effect, which can effectively fix the observation direction of the observation position 11-11.

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

[0096] The positioning groove 31-11 of the ratchet 31-1 is an asymmetric positioning groove 31-11-1, and the ratchet 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 erroneous rotation and ensure the adjustment direction of the angle.

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

[0098] refer to Figure 1 and Figure 1-4 The ratchet mechanism 32-1 can be an integral structure disposed inside the outer jacket 32 ​​to better ensure the positioning effect; or it can be a local structure disposed inside the outer jacket 32 ​​to reduce the movement resistance while ensuring the positioning effect. Figure 2 and Figure 2-4 .

[0099] refer to Figure 1-2 and Figure 2-2In 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, and 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 matching and embedding method has a very simple structure through the limiting effect of the axial limit groove 31-2.

[0100] Since the sleeve 1 of the adjustable periodontal endoscope sleeve 100 needs to be inserted into the periodontal pocket and kept deep in 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 under stress during use, so it is necessary to ensure that the sleeve 1 does not shift up and down axially. 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, thereby causing the observation mirror 200 to move up and fail to observe the periodontal pocket.

[0101] refer to Figure 6 to Figure 6-2 In this embodiment, the angle β between the gripping 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.

[0102] The angle adjustment mechanism 5 is a shaping mechanism 51 disposed at the distal end of the grip portion 2. Figure 6-1 In this embodiment, the shaping mechanism 51 and the holding portion 2 are installed together through a threaded connection.

[0103] The shaping mechanism 51 is made of a shaping material as a whole. Usually, the shaping mechanism 51 is made of a plastic metal, which not only ensures the shaping effect but also has good strength and maintains stability during use. This method of manufacturing the whole body of the shaping material can make the structure of the grip 2 still very simple, and it is very convenient to adjust during clinical procedures.

[0104] refer to Figure 7 and Figure 7-1 In this embodiment, the marking mechanism 6 is disposed 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 a marking mechanism 6.

[0105] The identification mechanism 6 can be a length scale provided on the detection part 11-12 at the far 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 read intuitively through the observation mirror 200. The identification mechanism 6 can also be an angle scale provided on the adjustment mechanism 3, and the adjustment angle of the direction of the observation position 11-11 can be identified by observing the rotation angle of the adjustment mechanism 3.

[0106] refer 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, and the distal end of the sleeve 1 is inserted into the periodontal pocket. 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.

[0107] 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 tooth side 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.

[0108] Embodiment 2: Adjustable periodontal endoscope sleeve of the present invention with a bidirectional ratchet adjustment mechanism

[0109] refer to Figures 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 .

[0110] refer to 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, 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.

[0111] refer to Figure 3 and Figure 3-4The ratchet mechanism 32-1 can be an integral structure disposed inside the outer jacket 32 ​​to better ensure the positioning effect; or it can be a local structure disposed inside the outer jacket 32 ​​to reduce the movement resistance while ensuring the positioning effect. Figure 4 and Figure 4-4 .

[0112] In this embodiment, since the adjustment mechanism 3 adopts a symmetrical structure, it can freely rotate in both directions during use, which makes the use process more convenient.

[0113] Embodiment 3: Adjustable periodontal endoscope sleeve of the present invention with interference fit adjustment mechanism

[0114] refer to Figure 5 to Figure 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] refer 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. The outer tube mechanism 32 is arranged at the proximal end of the holding part 2. Hold the holding 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, 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.

[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 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. Figure 5 and Figure 5-5 .

[0117] refer 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 causing difficulty in rotation due to friction force, a friction block 32-3 can be set on the outer tube mechanism 32, and 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 both achieve positioning between the inner tube mechanism 31 and the outer tube mechanism 32 and not be too large to cause difficulty in rotation.

[0118] Embodiment 4: Adjustable periodontal endoscope of the present invention

[0119] refer to Fig. 9In this embodiment, the adjustable periodontal endoscope 900 includes the observation mirror 200 and the adjustable periodontal endoscope sleeve 100 described in the previous embodiment.

[0120] The observation mirror 200 and the adjustable periodontal endoscope cover 100 can be manufactured as a whole to form the adjustable periodontal endoscope 900.

[0121] In this embodiment, the observation mirror 200 is a fiber-optic observation mirror 201; the gripping part 2 includes a shell 21, and a light source 22 and a circuit system 23 are arranged in the shell 21. The light source 22 provides illumination for the fiber-optic observation mirror 201, and the circuit system 23 connects the observation mirror 200 with the host 202 of the observation mirror 200; the distal end of the observation mirror 200 is arranged in the sleeve 1, and the adjustable periodontal endoscope sleeve 100 adjusts the observation direction of the observation position 11-11 to ensure the observation effect of the observation mirror 200 on the tooth side. For a micro periodontal endoscope, such as a periodontal endoscope with a diameter of less than 1 mm, the illumination method of the observation mirror 200 is usually optical fiber illumination. In the present utility model, this endoscope method using optical fiber illumination is referred to as the fiber-optic observation mirror 201. Since the optical fiber is easy to break and the side needs to be shielded during use, the light source is usually arranged at a position close to the observation end, such as usually arranged in the shell 21 of the gripping part 2. The circuit system 23 is connected to the host 202 and provides power to the light source 22 . The light source 22 provides lighting to the observation scope 200 through light-guiding optical fibers to ensure the normal operation of the observation scope 200 .

[0122] In this embodiment, since the adjustable periodontal endoscope 900 includes the adjustable periodontal endoscope cover 100, the direction of the observation position 11-11 can be adjusted by the adjustment mechanism 3 during use without adjusting the position and direction of the gripping portion 2. Therefore, during clinical use, observation of the periodontium in all directions can be achieved without moving the gripping portion 2, and the application range is very wide.

[0123] It should be noted that the structures disclosed and described herein can be replaced by other structures with the same effect, and the embodiments described in the present utility model are not the only structures for realizing the present utility model. Although the preferred embodiments of the present utility model have been described and described herein, it is clear to those skilled in the art that these embodiments are only examples, and those skilled in the art can make numerous changes, improvements and substitutions without departing from the present utility model. Therefore, the protection scope of the present utility model should be defined in accordance with the spirit and scope of the claims attached to the present utility model.
