Description

Technical Field

[0001] The present invention relates to the technical field of oral medical aids, and particularly to a magnifying glass for observing the oral clinical operation field on the lingual and palatal sides in the mouth. Background Art

[0002] An oral mirror is a medical device used for oral examination and treatment, and its principle is mainly based on optical reflection. Specifically, when the oral mirror is inserted into the patient's oral cavity, light is reflected from the lens on the oral mirror into the oral cavity, then reflected back to above the lens after passing through the tissue, and then observed by the eyes. In this way, doctors can clearly observe the situation inside the mouth.

[0003] In oral clinical operations, the lingual side and the palatal side are blind spots in the visual field, and the palatal side and the distal part of the molar area are even more difficult areas in the operation. In order to perform more accurate clinical operations on dental tissues in some blind spots of the oral visual field, increasing the operation accuracy of the blind spots in the oral visual field is a key step to improve the treatment success rate.

[0004] Currently, an oral mirror is usually used to observe the blind spots in the oral visual field. When in use, the patient needs to open the mouth first, and then the doctor holds the oral mirror with one hand and inserts the lens into the mouth, and holds the instrument with the other hand to perform relevant treatment operations. This not only affects the accuracy of the treatment, but also may cause discomfort and soft tissue damage to the patient due to the long-term opening of the mouth during tooth preparation. Summary of the Invention

[0005] The purpose of the present invention is to provide a magnifying glass for observing the oral clinical operation field on the lingual and palatal sides in the mouth to solve the above problems in oral clinical operations, which can facilitate doctors to better observe the blind spots in the oral visual field, and at the same time is beneficial to improving the accuracy of treatment operations and reducing the discomfort of patients and the risk of soft tissue damage.

[0006] The present invention is achieved by the following technical solutions:

[0007] The present invention provides a magnifying glass for observing the oral clinical operation field on the lingual and palatal sides in the mouth, including a lens body, a connecting piece and a bite pad. One end of the connecting piece is connected to the lens body, and the other end is connected to the bite pad. The connecting piece has flexibility and can maintain its shape after being bent by an external force.

[0008] In the above technical solution, the mirror body is fixed in the mouth through a bite pad. During use, there is no need for a doctor to hold it by hand, which facilitates the doctor to perform treatment operations with both hands. At the same time, the angle of the mirror body in the mouth can be adjusted by bending the connecting piece, so as to better observe the blind area of the intraoral vision. Therefore, in oral clinical treatment, dental tissue operations can be performed more accurately on some blind areas of vision. And by using the bite pad to fix the magnifying glass in the mouth, the discomfort of the patient after opening the mouth for a long time during tooth preparation is reduced, and the risk of soft tissue injury that may exist due to the change of the patient's mouth opening degree is lowered.

[0009] As a preferred solution of the present invention, the connecting piece is a plastic-coated shaped hose. Using a plastic-coated shaped hose to connect the mirror body and the bite pad, since the plastic-coated shaped hose is flexible, it can be bent under the action of an external force and can maintain its shape after bending. In this way, the mirror body can maintain the adjusted angle, and at the same time, the aesthetics is also better after coating with plastic.

[0010] As a preferred solution of the present invention, one end of the connecting piece is provided with a connecting rod, and the other end is provided with a buckle. The connecting rod is used to connect with the mirror body, and the buckle is detachably connected with the bite pad. By using a buckle to connect the bite pad, it is convenient to replace a bite pad with a suitable thickness according to the patient.

[0011] As a preferred solution of the present invention, the magnification of the mirror body is 3.5 - 5. By using a mirror body with the above magnification, it can be used for clear observation of dental tissue in the mouth, which is convenient for the doctor to operate.

[0012] As a preferred solution of the present invention, the mirror body is coated with a silica - nano - titanium dioxide coating. By coating the above coating on the reflecting surface of the mirror body, it is possible to prevent the mirror surface from fogging during use.

[0013] As a preferred solution of the present invention, the diameter of the mirror body is 10mm - 12mm.

[0014] As a preferred solution of the present invention, the bite pad is made of medical silicone material. Using medical silicone to make the bite pad, this material can meet the requirements of the internal oral use environment; at the same time, the silicone material is softer and has better elasticity, making it more comfortable for the patient to bite and not hurting the patient's teeth.

[0015] As a preferred solution of the present invention, one side of the bite pad is provided with a protrusion, and the protrusion is used to connect with the connecting piece.

[0016] As a preferred embodiment of the present invention, the occlusal pad is provided with arc-shaped occlusal grooves on two sides in contact with the upper and lower dental arches respectively. By providing arc-shaped occlusal grooves on the upper and lower sides of the occlusal pad respectively, when placed in the patient's mouth, the molar regions of the patient's upper and lower dental arches will occlude within the above-mentioned occlusal grooves, which can prevent slipping during occlusion and cause the occlusal pad to move relative to the molar region.

[0017] As a preferred embodiment of the present invention, the thickness of the occlusal pad is 1.5 cm - 2.5 cm. For different sizes of the patient's mouth, occlusal pads with different thickness specifications can be replaced for use.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] The magnifying glass in the present invention can be fixed in the mouth through the occlusal pad. When in use, it does not need to be held by the doctor, which is convenient for the doctor to perform treatment operations with both hands. At the same time, the angle of the lens body in the mouth can be adjusted by bending the connecting piece to better observe the blind area in the mouth. Therefore, in oral clinical operations, dental tissue operations can be performed more precisely on some blind areas of the visual field. And by using the occlusal pad to fix the magnifying glass in the mouth, the discomfort of the patient after opening the mouth for a long time during the dental tissue operation is reduced, and the risk of soft tissue injury that may exist due to the change of the patient's mouth opening degree is lowered.

[0036] In oral clinical treatment, the lingual and palatal sides are blind spots in the visual field, and the palatal side and distal of the molar area are even more difficult areas in clinical operations. Currently, an oral mirror is usually used to observe the blind spots in the oral cavity. When in use, the doctor needs to hold the oral mirror in one hand and insert the lens into the mouth, and hold the instrument in the other hand to perform relevant treatment operations. This not only affects the accuracy of the treatment, but also may cause discomfort and soft tissue damage to the patient due to long-term opening of the mouth.

[0037] In view of this, through in-depth research, the inventor has invented a magnifying glass for observing the visual field of oral clinical operations on the lingual and palatal sides of the mouth. It fixes the magnifying glass in the mouth through the occlusal pad 3, and no longer requires the doctor to hold it by hand. The doctor's freed hand can be used for assisting treatment operations. At the same time, since the occlusal pad 3 occludes and supports between the molar areas of the patient's upper and lower dental arches, the patient can maintain an open mouth state for a long time, reducing the discomfort of the patient and the risk of soft tissue damage.

[0038] Please refer to Figures 1 to 4, a magnifying glass for observing the oral clinical operation field on the lingual-palatal side in the mouth provided in the embodiment of the present application, includes a lens body 1, a connecting member 2 and a bite pad 3. One end of the connecting member 2 is connected to the lens body 1, and the other end is connected to the bite pad 3. The connecting member 2 is flexible and can maintain its shape after being bent by an external force.

[0039] In this embodiment, the lens body 1 and the bite pad 3 are respectively installed at both ends of the connecting member 2. During use, the bite pad 3 is placed in the patient's mouth, and the bite pad 3 is fixed in the mouth by using the molar area. The bite pad 3 is supported between the molar areas of the patient's upper and lower dental arches. In this way, the patient can maintain a wide-open mouth state for a long time, and at the same time, the lens body 1 is also placed in the patient's mouth.

[0040] At the same time, since the connecting member 2 is flexible and can maintain its shape after being bent by an external force, the doctor can apply a force to the connecting member 2 by means of a tool, so that the connecting member 2 bends in the desired direction, thereby adjusting the angle of the lens body 1 in the mouth appropriately to achieve better observation of the visual blind area of the intraoral operation.

[0041] The magnifying glass in the present application is fixed in the mouth through the bite pad 3. During use, it does not need to be held by the doctor, which is convenient for the doctor to perform treatment operations with both hands. At the same time, the angle of the lens body 1 in the mouth can be adjusted by bending the connecting member 2 to better observe the visual blind area in the mouth. Therefore, in oral clinical operations, dental tissue operations can be performed more accurately on some visual blind areas. And by using the bite pad 3 to fix the magnifying glass in the mouth, the discomfort of the patient after opening the mouth for a long time during tooth preparation is reduced, and the risk of soft tissue injury that may exist due to the change of the patient's mouth opening degree is reduced.

[0042] According to some embodiments of the present application, the connecting member 2 is a rubber-coated shaped hose. Using a rubber-coated shaped hose to connect the lens body 1 and the bite pad 3, since the rubber-coated shaped hose is flexible, it can be bent under the action of an external force and can maintain its shape after bending. In this way, the lens body 1 can maintain the adjusted angle, and at the same time, the aesthetics is also better after rubber coating.

[0043] The rubber-coated shaped hose is made of a metal shaped hose as one of the primary materials and is refined by covering a layer of rubber material on the outside to have the characteristics of a shaped hose. The outer covering of the rubber material makes the appearance and practicality of the product more suitable for people's aesthetic requirements and improves the service life of the product. Depending on the rubber material used, the rubber-coated shaped hose is divided into a rubber-coated heat shrinkable tube shaped hose (heat shrinkable tube shaped hose) and a rubber-coated silicone shaped hose.

[0044] According to some embodiments of the present application, one end of the connecting member 2 is provided with a connecting rod 4, and the other end is provided with a buckle 5. The connecting rod 4 is used to connect with the mirror body 1, and the buckle 5 is detachably connected to the occlusal pad 3. By using the buckle 5 to connect the occlusal pad 3 and the connecting member 2, it is convenient to replace the occlusal pad 3 with a suitable thickness according to the patient. It should be noted that using a buckle connection is just a feasible way, and of course, other detachable connection structures can also be used. For example, a plastic threaded rod is fixedly arranged on the side of the occlusal pad 3, and a matching threaded hole is arranged at the end of the connecting member 2, and the two are connected by a threaded method.

[0045] Specifically, one end of the connecting rod 4 is fixedly connected to the rubber-coated shaped hose, and the other end is recessed to form a connecting hole 41. A connecting post 11 is arranged at the edge of the mirror body 1. During installation, the connecting post 11 at the edge of the mirror body 1 is tightly inserted into the connecting hole 41 at the end of the connecting rod 4. One end of the buckle 5 is fixedly connected to the rubber-coated shaped hose, and the other end has a card slot 51. During installation, after the buckle 5 is opened, the protruding part 31 on one side of the occlusal pad 3 is inserted into the card slot 51, and then the buckle 5 is closed to fix the protruding part 31 in the buckle 5.

[0046] According to some embodiments of the present application, the magnification of the mirror body 1 is 3.5 - 5. Preferably, the mirror body 1 with a magnification of 3.5X is used, which can be used for clear observation of dental tissues in the mouth and is convenient for doctors to operate.

[0047] According to some embodiments of the present application, the mirror body 1 is coated with a silica-nano titanium dioxide coating. By coating the above coating on the reflecting surface of the mirror body 1, fogging of the mirror surface during use can be prevented.

[0048] According to some embodiments of the present application, the diameter of the mirror body 1 is 10mm - 12mm. It should be noted that the diameter and thickness of the mirror body 1 can be designed with reference to existing mouth mirrors. Specifically, the mirror body 1 is composed of a lens and a plastic body covering the back and edge of the lens, and the connecting post 11 is arranged on the outer peripheral wall of the plastic body.

[0049] According to some embodiments of the present application, the occlusal pad 3 is made of medical silicone material. Using medical silicone to make the occlusal pad 3, this material is non-toxic and resistant to saliva corrosion, and can meet the requirements of the oral internal use environment. At the same time, the silicone material is softer and has better elasticity, making it more comfortable for the patient to bite.

[0050] According to some embodiments of the present application, a protruding portion 31 is provided on one side of the occlusal pad 3, and the protruding portion 31 is used to connect to the connecting member 2. By providing the protruding portion 31, it is used to connect to the buckle 5 at one end of the rubber-coated shaped hose. In order to improve the rigidity of the protruding portion 31 and make its connection with the buckle 5 more stable, an embedded rod body can be provided in the protruding portion 31, and the rod body extends inward from the outer end of the protruding portion 31 by a certain length into the occlusal pad 3.

[0051] According to some embodiments of the present application, arc-shaped occlusal grooves 32 are respectively provided on the two side surfaces of the occlusal pad 3 that are in contact with the upper and lower dental arches. By respectively providing arc-shaped occlusal grooves 32 on the upper and lower sides of the occlusal pad 3, when placed in the patient's mouth, the molar areas of the patient's upper and lower dental arches will occlude within the above-mentioned occlusal grooves 32, which can prevent the occlusal pad 3 from moving relative to the molar area due to slipping during the occlusion process. The occlusal pad 3 can be square or rectangular.

[0052] According to some embodiments of the present application, the thickness of the occlusal pad 3 is 1.5 cm - 2.5 cm. Specifically, three thickness specifications of 1.5 cm, 2 cm, and 2.5 cm can be formed, and can be replaced and used according to the size of different patients' mouths.

[0053] The method of using the magnifying glass in the present application: The patient fixes the magnifying glass in the mouth by occluding the occlusal pad 3 with the molar area. The occlusal pad 3 can support the patient to open the mouth for a long time. After replacing the occlusal pad 3, it is connected and fixed by the buckle 5. During the operation in the mouth, the doctor observes other visual field blind areas such as the lingual and palatal sides in the mouth through the lens body 1 part, which is convenient for the doctor to operate. During the operation process, the doctor can change the position presented by the lens body 1 by adjusting the rubber-coated shaped hose.

[0054] The magnifying glass in the present application is convenient for clinical operations on the tooth body parts in the visual field blind areas during oral operations, improves the accuracy of diagnosis and treatment, and thus can improve the success rate of treatment. At the same time, by using the occlusal pad 3 to fix the magnifying glass in the mouth, the discomfort of the patient after opening the mouth for a long time is reduced, and the risk of soft tissue injury that may exist due to the change of the patient's mouth opening degree is reduced; especially it can be used during operations such as tooth preparation and resin filling.
