Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of auxiliary instruments for oral treatment, in particular to be used for the mirror cover of periodontal endoscope and periodontal endoscope in cooperation with 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 curettage is the most basic treatment method for all types of periodontal diseases, and subgingival curettage and root surface leveling are important steps, especially for patients with periodontal pockets. Subgingival curettage is the main means of removing dental calculus and dental plaque on the root surface in the periodontal pocket.

[0004] The current treatment process is to use a fine subgingival curettage instrument 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 feeling, making the root surface smooth. During or after the curettage, a sharp probe must be used to carefully probe whether the subgingival dental calculus is completely removed and whether the root surface is smooth to determine the curettage effect.

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

[0006] However, in the process of using periodontal endoscopes for auxiliary treatment, in order to meet the requirements of infection control, there are usually two ways to handle the endoscope: one is to sterilize the endoscope directly and reuse it; the other is to use a disposable protective sleeve to protect and isolate the endoscope. Since there are strict sterilization process standards for directly sterilizing the endoscope, many hospitals and clinics have started to choose to use disposable protective sleeves. However, since the head end of the protective sleeve is a closed structure, the lens of the endoscope and the end surface of the sleeve usually cannot fit together due to the compressed air pressure near the head end after the endoscope is inserted, so the gap is very easy to cause light path deviation, glare, chromatic aberration, distortion and other adverse phenomena during imaging due to the effects of refraction, scattering and reflection of light, affecting the observation effect. Therefore, the protective sleeve is further improved in this application to eliminate the adverse effects of the gap on the observation effect. SUMMARY

[0007] The utility model discloses a periodontal endoscope lens cover, through the gap between lens and sleeve end face liquid filling, the way of constructing liquid lens layer eliminates the adverse effect of the observation effect caused by the refraction, scattering of light etc.

[0008] The utility model discloses a periodontal endoscope lens cover, through the gap between lens and sleeve end face liquid filling, the way of constructing liquid lens layer eliminates the adverse effect of the observation effect caused by the refraction, scattering of light etc.

[0009] A, the sleeve 1 contains lens protection pipe 11 and connecting portion 12, the lens protection pipe 11 contains work channel 11-1, the distal end of lens protection pipe 11 is equipped with the closed observation site 11-2, the proximal end of lens protection pipe 11 is equipped with water inlet 11-3 and instrument entrance 11-4;

[0010] B, the sleeve 1 is connected through connecting portion 12 with the distal end of holding portion 2;

[0011] C, the observation mirror 200 enters the lens protection pipe 11 through the instrument entrance 11-4, approaches the observation site 11-2 through the work channel 11-1, and liquid enters the work channel 11-1 through the water inlet 11-3 and accumulates to form a liquid lens 3 that can fill the gap between the observation plane 200-1 of the observation mirror 200 and the observation site 11-2, which can ensure that the observation field of the observation mirror 200 remains clear during use.

[0012] Generally, the observation site 11-2 is made of transparent optical material. Since it adopts a closed design, a closed water tank structure can be formed at the observation site 11-2. When transparent liquid is injected from the water inlet 11-3, it can flow along the work channel 11-1 to the observation site 11-2 and accumulate to form a liquid pool. When the observation mirror 200 is inserted into the lens protection pipe 11 and approaches the observation site 11-2, the liquid can submerge the observation plane 200-1 of the observation mirror 200, completely fill the gap between the observation plane 200-1 and the observation site 11-2, and thus form the liquid lens 3. Since the liquid completely fills the gap, an integrated medium body that completely adheres to the lens surface is formed between the observation plane 200-1 and the observation site 11-2. Since there is no air, when light enters the medium body, it will not cause light path deviation, glare, chromatic aberration, distortion, and other adverse phenomena that affect the observation effect, thus ensuring that the observation field can remain clear during use.

[0013] The lens protection tube 11 is detachably connected to the connecting part 12. Since the lens protection tube 11 has medical infection control requirements in use for the sake of safety and hygiene, the sleeve 1 needs to be replaced for each new patient. In order to facilitate clinical operation and save medical costs, the lens protection tube 11 is detachably connected to the connecting part 12, so that only the lens protection tube 11 needs to be replaced in clinical use. In actual application, the connecting part 12 can also be detachably connected to the holding part 2, so that the sleeve 1 is replaced as a whole in clinical use.

[0014] The lens protection tube 11 is further provided with a liquid overflow mechanism 11-5. In order to prevent liquid from overflowing from the sleeve 1 during use and causing pollution, the lens protection tube 11 is further provided with a liquid overflow mechanism 11-5, so that the liquid can be directly discharged outside to prevent the oral cavity from being polluted.

[0015] The distal end of the periodontal endoscope sleeve 100 is further provided with a detection part 4. The detection part 4 is usually made into a probe-shaped member with a smooth tip, which can be deeply inserted into the periodontal pocket for detection, and can better expose the operation field of view during treatment to achieve better operation observation.

[0016] The periodontal endoscope sleeve 100 is further provided with a flushing mechanism 5. The flushing mechanism 5 can flush the observation site 11-2 to ensure that the observation site 11-2 is not blocked by blood and the like, and maintain good observation effect. Since the gingival sulcus needs to be flushed during subgingival treatment to ensure that subgingival bleeding does not affect the observation and treatment of the doctor, the flushing liquid of the flushing mechanism 5 also needs to flush the gingival sulcus.

[0017] The flushing mechanism 5 comprises a flushing channel 51, and the outlet 51-1 of the flushing channel 51 is arranged on the upper side of the observation site 11-2, which can flush the observation site 11-2 and the tissue in the oral cavity.

[0018] This upper outlet arrangement enables the flushing liquid to flow out of the outlet of the flushing channel 51 to first flush the observation site 11-2, ensuring that the observation site 11-2 is not blocked, and the flushing liquid continues to flow down along the detection part 4, i.e. enters the gingival sulcus along the detection part 4 to flush the gingival sulcus. Therefore, one flushing channel can meet the two flushing requirements at the same time, without the need to separately arrange two flushing mechanisms to achieve different flushing functions.

[0019] The flushing mechanism 5 is made of a flexible flushing pipe 52, which is manufactured with the lens protection pipe 11 by double pipe. In order to facilitate assembly and production, the flushing mechanism 52 is usually made of flexible plastic pipe, and in order to facilitate the deformation and adjustment of the dental mirror 200, the lens protection pipe 11 is usually made of soft plastic pipe, therefore, the flushing pipe 52 can be integrally manufactured with the lens protection pipe 11 by double pipe method, only the inlet and outlet are separated, which can be assembled integrally during assembly, which is very convenient.

[0020] The dental mirror sleeve 100 can also be an adjustable dental mirror sleeve. The adjustable dental mirror sleeve can adjust the relative position between the observation part 11-2, the detection part 4 and the holding part 2 through the lens adjusting mechanism, so as to ensure that the dental mirror 200 always faces the tooth side for effective observation. The adjustment mode of the lens adjusting mechanism can be rotation, sliding groove, hinge and other different adjustment modes.

[0021] The angle β between the holding part 2 and the sleeve 1 is adjusted by the angle adjusting mechanism 6. The angle β can be adjusted by the angle adjusting mechanism 6 as needed, so as to adapt to different periodontal and tooth shapes and angles.

[0022] The angle adjusting mechanism 6 is a shaping mechanism 61 arranged at the distal end of the holding part 2.

[0023] The shaping mechanism 61 is integrally manufactured by shaping material. Usually, the shaping mechanism 61 is made of shapeable metal, which not only ensures the shaping effect but also has good strength, and maintains the stability during use. This way of integrally manufacturing by shaping material can make the structure of the holding part 2 still simple, and the adjustment is very convenient during clinical process.

[0024] The dental mirror sleeve 100 is also provided with a dental mirror positioning mechanism 7. Since the sleeve 1 needs to be inserted into the periodontal pocket and kept in the deep part of the periodontal pocket during use to ensure that the dental 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 does not move axially up and down, therefore, the dental mirror positioning mechanism 7 is usually arranged on the connecting mechanism 12. The dental mirror positioning mechanism 7 can be a positioning plug 71 made of elastic material with a dental mirror insertion hole, which can ensure that the lens protection pipe 11 does not move axially up and down during operation by the ring force of the elastic material.

[0025] The holding part 2 comprises a holding handle 21.

[0026] The handle 21 is provided with a mounting groove 21-1. The lens protection tube 11, the flushing pipe 52 and other components can be arranged in the mounting groove 21-1, so that these components do not affect the operation of the doctor during operation.

[0027] During clinical use, the observation mirror 200 enters the lens protection tube 11 through the instrument inlet 11-4, approaches the observation site 11-2 through the working channel 11-1, liquid enters the working channel 11-1 at the distal end through the water inlet 11-3, completely fills the gap between the observation plane 200-1 of the observation mirror 200 and the observation site 11-2, and forms the liquid lens 3. The liquid lens 3 can ensure that the observation field of the observation mirror 200 remains clear during use.

[0028] The periodontal endoscope 900 comprises the observation mirror 200 and the periodontal endoscope sleeve 100.

[0029] The observation mirror 200 is a fiber type observation mirror 201. The mounting groove 21-1 of the holding part 2 is provided with a light source 22 and a circuit system 24. The light source 22 provides illumination for the fiber type observation mirror 201. The circuit system 24 connects the observation mirror 200 and the host 202 of the observation mirror 200. The observation lens of the observation mirror 200 is arranged at the distal end of the sleeve 1 and approaches the observation site 11-2. The liquid lens 3 ensures that the observation of the observation mirror 200 remains clear during use. 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. In the utility model, this endoscope mode using fiber illumination 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 usually arranged in the shell 21 of the holding part 2. The host 202 is connected through the circuit system 24 and provides power for the light source 22. The light source 22 provides illumination for the observation mirror 200 through the light guide fiber, so as to ensure the normal work of the observation mirror 200.

[0030] The observation mirror 200 is an LED type observation mirror 203; a light source 22 and circuit system 24 are arranged at the distal end of the LED type observation mirror 203, the light source 22 is an LED lamp, and the circuit system 24 is connected with the observation mirror 200 and the main machine 202 of the observation mirror 200; the observation lens of the observation mirror 200 is arranged at the distal end of the sleeve 1 and is close to the observation site 11-2, and the liquid lens 3 ensures that the observation of the observation mirror 200 is continuously clear during use. Since the light source 22 is an LED lamp, only power supply through an electric signal is needed to complete the illumination, and the assembly is simpler, and the illumination effect of the LED lamp is very good due to the direct front illumination.

[0031] The periodontal endoscope 900 contains the periodontal endoscope sleeve 100, and during use, the periodontal endoscope sleeve 100 can be replaced without cleaning and disinfecting the observation mirror 200 itself, which is very convenient for clinical use. In particular, the liquid lens 3 arranged in the lens protection tube 11 of the periodontal endoscope sleeve 100 enables the observation plane 200-1 of the observation mirror 200 to maintain good observation effect even if it is not attached to the observation site, which is very convenient for clinical use.

[0032] The periodontal endoscope sleeve contains a sleeve 1 and a holding part 2. The sleeve 1 contains a lens protection tube 11 and a connecting part 12; the lens protection tube 11 contains a working channel 11-1, the distal end of the lens protection tube 11 is provided with a closed observation site 11-2, and the proximal end of the lens protection tube 11 is provided with a water inlet 11-3 and an instrument inlet 11-4. The sleeve 1 is connected with the distal end of the holding part 2 through the connecting part 12. The observation mirror 200 enters the lens protection tube 11 through the instrument inlet 11-4, approaches the observation site 11-2 through the working channel 11-1, liquid enters the working channel 11-1 through the water inlet 11-3 and accumulates at the distal end to form a liquid lens 3 that can fill the gap between the observation plane 200-1 of the observation mirror 200 and the observation site 11-2, and the liquid lens 3 can ensure that the observation field of view of the observation mirror 200 is continuously clear during use. The periodontal endoscope 900 contains the periodontal endoscope sleeve 100, and during use, the periodontal endoscope sleeve 100 can be replaced without cleaning and disinfecting the observation mirror 200 itself, which is very convenient for clinical use. In particular, the liquid lens 3 arranged in the lens protection tube 11 of the periodontal endoscope sleeve 100 enables the observation plane 200-1 of the observation mirror 200 to maintain good observation effect even if it is not attached to the observation site 11-2, which is very convenient for clinical use.

[0052] Example 1: Periodontal endoscope sleeve of the utility model

[0053] Reference Figures 1 to 4 In the embodiment, the periodontal endoscope sleeve 100 comprises a sleeve 1 and a holding part 2.

[0054] Reference Figure 1-4 , the sleeve 1 comprises a lens protection pipe 11 and a connecting part 12; the lens protection pipe 11 comprises a working channel 11-1, the distal end of the lens protection pipe 11 is provided with a closed observation site 11-2, and the proximal end of the lens protection pipe 11 is provided with a water inlet 11-3 and an instrument inlet 11-4. The sleeve 1 is connected with the distal end of the holding part 2 through the connecting part 12.

[0055] The observation mirror 200 enters the lens protection pipe 11 through the instrument inlet 11-4, approaches the observation site 11-2 through the working channel 11-1, liquid can be injected or connected with water of a dental chair to enter the working channel 11-1 through the water inlet 11-3 to accumulate at the distal end to form a liquid lens 3 capable of filling the gap between the observation plane 200-1 of the observation mirror 200 and the observation site 11-2, and the liquid lens 3 can ensure that the observation field of view of the observation mirror 200 remains clear during use.

[0056] Reference Figure 1-2The observation site 11-2 is usually made of transparent optical material. Since the design is closed, a closed water tank structure is formed at the observation site 11-2. When the transparent liquid is injected from the water inlet 11-3, it flows along the working channel 11-1 to the observation site 11-2 and accumulates to form a liquid pool. When the observation mirror 200 is inserted into the lens protection tube 11 close to the observation site 11-2, the liquid can submerge the observation plane 200-1 of the observation mirror 200, completely fill the gap between the observation plane 200-1 and the observation site 11-2, and form the liquid lens 3. Since the gap is completely filled with liquid, an integral medium body that completely adheres to the surface of the lens is formed between the observation plane 200-1 and the observation site 11-2. Since there is no air, the light entering the medium body will not cause light path deviation, glare, chromatic aberration, distortion, and other adverse phenomena that affect the observation effect during the imaging process due to refraction, scattering, reflection, and other phenomena of the light. Therefore, the observation field of view can be continuously clear during use.

[0057] The lens protection tube 11 is detachably connected to the connecting portion 12. Since the lens protection tube 11 has medical infection control requirements for safety and hygiene during use, a new sleeve 1 needs to be replaced for each new patient. In order to facilitate clinical operation and save medical costs, the lens protection tube 11 is detachably connected to the connecting portion 12, so that only the lens protection tube 11 needs to be replaced during clinical use. In actual application, the connecting portion 12 can also be detachably connected to the holding portion 2, so that the sleeve 1 is replaced as a whole during clinical use.

[0058] Reference Figure 2 In order to prevent liquid from overflowing from the sleeve 1 during use and causing pollution, a drainage tube is connected to the water inlet 11-3 and led out of the body to form the overflow mechanism 11-5, so that the liquid can be directly discharged out of the body to prevent the oral cavity from being contaminated.

[0059] Reference Figure 1 , Figure 2 and Figure 3 The distal end of the periodontal endoscope sleeve 100 is also provided with a detection portion 4. The detection portion 4 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 achieve better operation observation.

[0060] The periodontal endoscope sleeve 100 is also provided with a flushing mechanism 5. The flushing mechanism 5 can flush the observation site 11-2 to ensure that the observation site 11-2 is not blocked by blood and the like, and maintain good observation effect. Since when performing subgingival treatment, in order to ensure that subgingival bleeding does not affect the observation and treatment of the doctor, the gingival sulcus needs to be flushed, therefore, the flushing liquid of the flushing mechanism 5 also needs to flush the gingival sulcus.

[0061] Reference Figure 1-3 And Figure 3-1 The flushing mechanism 5 contains a flushing channel 51, and the outlet 51-1 of the flushing channel 51 is arranged on the upper side of the observation site 11-2, which can flush the observation site 11-2 and the tissue in the oral cavity.

[0062] This upper outlet arrangement allows the flushing liquid to flow out of the outlet of the flushing channel 51 first, thereby flushing the observation site 11-2 to ensure that the observation site 11-2 is not blocked, and at the same time, the flushing liquid continues to flow down along the detection part 4, that is, along the detection part 4 into the gingival sulcus to flush the gingival sulcus. Therefore, one flushing channel can meet the two flushing requirements at the same time, and two flushing mechanisms are not needed to achieve different flushing functions.

[0063] The flushing mechanism 5 is composed of a flexible flushing pipe 52, and the flushing pipe 52 and the lens protection pipe 11 are manufactured by double-pipe. In order to facilitate assembly and production, the flushing mechanism 52 is usually a flexible plastic pipe, and in order to facilitate the deformation and adjustment of the observation mirror 200, the lens protection pipe 11 is usually made of soft plastic pipe. Therefore, the flushing pipe 52 can be integrally manufactured with the lens protection pipe 11 by the double-pipe method, and only the inlet and outlet need to be separately arranged, which can be integrally assembled during assembly, which is very convenient.

[0064] The holding part 2 contains a holding handle 21.

[0065] Reference Figure 1 The handle 21 is provided with a mounting groove 21-1. The mounting groove 21-1 can be provided with the lens protection pipe 11, the flushing pipe 52 and the like, so as to ensure that these components do not affect the operation of the doctor during operation.

[0066] The proximal end of the holding part 2 is provided with a dental chair connecting part 23, and the proximal end of the flushing pipe 52 is arranged on the dental chair connecting part 23 to form the inlet of the flushing channel 51, which is connected with the waterway of the dental chair to flush the gingiva.

[0067] The periodontal endoscope sleeve 100 can also be an adjustable periodontal endoscope sleeve. The adjustable periodontal endoscope sleeve can adjust the relative position between the observation site 11-2, the detection part 4 and the holding part 2 through a lens adjustment mechanism, so as to ensure that the observation mirror 200 always effectively observes the tooth side. The adjustment mode of the lens adjustment mechanism can be rotation, sliding groove, hinge and other different adjustment modes.

[0068] With reference to Figure 4 , the angle β between the holding part 2 and the sleeve 1 is adjusted by the angle adjustment mechanism 6. The angle β can be adjusted by the angle adjustment mechanism 6 as needed to adapt to different periodontal and tooth shapes and angles.

[0069] The angle adjustment mechanism 6 is a shaping mechanism 61 arranged at the distal end of the holding part 2.

[0070] The shaping mechanism 61 is integrally manufactured by a shaping material. Generally, the shaping mechanism 61 is made of a shapeable metal, which not only ensures the shaping effect but also has good strength and maintains stability during use. This integrally manufacturing method by a shaping material can make the structure of the holding part 2 still simple and convenient to adjust during clinical procedures.

[0071] With reference to Figure 1-3 and Figure 3-1 , the periodontal endoscope sleeve 100 is also provided with an observation mirror positioning mechanism 7. 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 observes 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 does not move axially up and down, and therefore the observation mirror positioning mechanism 7 is usually arranged on the connecting mechanism 12. In this embodiment, the inlet of the connecting mechanism 12 is a trumpet mouth, the observation mirror positioning mechanism 7 is a positioning plug 71 made of elastic material with an observation mirror insertion hole, the positioning plug 71 is inserted into the trumpet mouth of the connecting mechanism 12, and the lens protection tube 11 is inserted into the observation mirror insertion hole. The ring force of the elastic material ensures that the lens protection tube 11 does not move axially up and down during operation.

[0072] In clinical use, the observation mirror 200 enters the lens protection tube 11 through the instrument entrance 11-4, approaches the observation site 11-2 through the working channel 11-1, and liquid enters the working channel 11-1 at the distal end to completely fill the gap between the observation plane 200-1 of the observation mirror 200 and the observation site 11-2, thereby forming the liquid lens 3, which can ensure that the observation field of view of the observation mirror 200 remains clear during use.

[0073] In this embodiment, the liquid lens 3 completely fills the gap between the observation plane 200-1 and the observation site 11-2, thereby forming a complete medium body that completely adheres to the surface of the lens. Since there is no air, the light entering the medium body will not cause light path deviation, glare, chromatic aberration, distortion, and other adverse phenomena that affect the observation effect, thereby ensuring that the observation field of view remains clear during use.

[0074] Embodiment 2: Periodontal endoscope

[0075] Reference Figure 5 In this embodiment, the periodontal endoscope 900 includes the observation mirror 200 and the periodontal endoscope sleeve 100 of the foregoing embodiments.

[0076] Reference Figure 3 And Figure 3-1 The observation mirror 200 can be a fiber optic observation mirror 201. The mounting groove 21-1 of the holding portion 2 is provided with a light source 22 and a circuit system 24. The light source 22 provides illumination for the fiber optic observation mirror 201. The circuit system 24 connects the observation mirror 200 and the main machine 202 of the observation mirror 200. The observation lens of the observation mirror 200 is arranged at the distal end of the lens protection tube 11, approaches the observation site 11-2, and the liquid lens 3 ensures that the observation of the observation mirror 200 remains clear during use. For a miniature 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 fiber optic illumination. In this embodiment, this endoscope method using fiber optic illumination is referred to as the fiber optic 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 in the shell 21 of the holding portion 2. The main machine 202 is connected through the circuit system 24 and provides power to the light source 22. The light source 22 provides illumination for the observation mirror 200 through the light guide fiber, thereby ensuring the normal operation of the observation mirror 200.

[0077] Reference Figure 1-2 And Figure 1-3 The observation mirror 200 can also be an LED type observation mirror 203; the distal end of the LED type observation mirror 203 is provided with a light source 22 which is an LED lamp and circuit system 24 which connects the observation mirror 200 and the host 202 of the observation mirror 200; the observation lens of the observation mirror 200 is arranged at the distal end of the lens protection tube 11 and is close to the observation site 11-2; the liquid lens 3 ensures that the observation of the observation mirror 200 remains clear during use. Since the light source 22 is an LED lamp, only power supply through electrical signal is needed to complete the lighting, and the assembly is simpler, and the LED lamp is directly front lighting, so the lighting effect is very good.

[0078] Reference Figure 5 In clinical use, the observation mirror 200 is connected to the host 201, the observation mirror 200 is inserted into the lens protection tube 11 through the instrument inlet 11-4 and is close to the observation site 11-2, the dental chair waterway is connected to the inlet 51-2 of the flushing pipe 52, and then water is injected into the lens protection tube 11 through the water inlet 11-3 until the observation plane 200-1 is submerged, and then the use is started.

[0079] In this embodiment, the periodontal endoscope 900 contains the periodontal endoscope sleeve 100, and during use, the periodontal endoscope sleeve 100 can be replaced without cleaning and disinfecting the observation mirror 200 itself, which is very convenient for clinical use.
