[Prior art]

 2. Description of the Related Art Conventionally, an oral endoscope is provided with a mirror integrally provided at one end of a handle, and a mirror portion is inserted into the oral cavity to examine not only the back side of teeth and back teeth but also the state of the throat. Therefore, the portion of the handle must be long enough to be inserted into the oral cavity so that the back of the throat can be seen, and has a certain length. At the same time, because the inside of the oral cavity is dark, it was necessary to illuminate extremely bright light from outside the oral cavity with a lighting device when examining the inside of the oral cavity or when using it in a general household. Therefore, in many cases, an extremely expensive lighting device is required, or since there is no such equipment in home medical care, lighting is applied from outside the oral cavity with a flashlight or the like. In addition, in such an oral endoscope, the handle and the mirror are usually formed integrally, and in a medical examination or the like, the oral endoscope itself has to be replaced every time the patient is replaced. Things.

[0003]

[Problems to be solved by the invention]

 Therefore, first, conventional oral endoscopes are of a certain length and long, and in the case of home-based medical treatment, such as going to a patient's home or the like at the time of medical treatment, carrying around is extremely disturbing, and some compactness is required. Was desired. In addition, a compact one is desired not only for home visits, but also for cases such as storage and regular storage at home.

[0004] Next, lighting equipment is also extremely expensive as medical equipment, and even with these equipment, there is a drawback that light hardly hits the back side of the teeth and the like. In addition, when using an oral endoscope at a patient's home or the like at the time of a house call, etc., there is no such equipment, so it is necessary to perform an examination while illuminating from outside the oral cavity with a lighting device such as a flashlight. Not only was it not easy to see, but at least one hand had to hold the luminaire, which was extremely inconvenient. Similarly, even in ordinary households, it was not possible to see the inside of the oral cavity unless the inside of the oral cavity was illuminated using some light source from the outside of the oral cavity.

[0005] Next, it is desired that the number of medical devices be as small as possible, especially when visiting homes and the like. Therefore, even when examining a large number of patients, it is not necessary to walk with an oral endoscope for the number of members. It was desired that the medical treatment could be performed with as little equipment as possible. As described above, the present invention solves the above-mentioned problems, and makes one oral endoscope extremely compact when storing or carrying it, while having an appropriate length during medical treatment and brightening the inside of the oral cavity. The light source for performing the treatment is attached to the oral endoscope itself to make it easier to see the affected part, and the mirror part of one oral endoscope can be replaced. An object of the present invention is to provide an extremely easy-to-use, easy-to-carry and hygienic oral endoscope for use.

An oral endoscope consisting of an arm body and a mirror connected to the arm body, and devised an oral endoscope that can adjust the distance between the handle and the mirror by pulling out the arm body stored in the handle. is there. Therefore, if the arm is stored in the handle during storage, it is extremely compact. On the other hand, by pulling out the arm from the handle, the arm becomes long and the inside of the oral cavity can be examined.

[0007] Further, an oral endoscope comprising a hollow-shaped handle having a bottom, an arm body inserted into the handle so as to be housed or pulled out, and a mirror connected to the arm body according to the invention according to claim 2. The above object can also be achieved by providing an oral endoscope in which a light source is provided at a mirror-side tip portion of the arm body. In other words, when the arm is pulled out from the handle for examination, the back of the oral cavity and the back teeth are dim and difficult to examine, but the light near the mirror can be brightened by having a light source at the tip of the pulled out arm. is there.

Alternatively, a hollow-shaped handle having a bottom portion according to the invention according to claim 3 and a handle having a very small number of devices instead of preparing a large number of oral endoscopes when viewing a large number of patients. A mouth endoscope having an arm body inserted and retractably inserted into the inside thereof and a light source provided at a distal end portion of the arm body, wherein a mirror mounting body is provided at one end of the arm body where the light source is provided. By replacing the mirror through the mirror mount for each patient with an oral endoscope with a removable mirror mounted through the mirror, the diagnosis can be performed with an extremely small amount of equipment, and the above object can be achieved.

A hollow handle having a bottom portion according to the invention according to claim 4, an arm body inserted into the handle so as to be housed or pulled out freely, and a mirror having a mirror mounting body at one end of the arm body. The same purpose as described above can be achieved by a detachably mounted oral endoscope.

The power supply built in the inside of the flange-shaped part is separated from the bottom inside by a switch rod. When the arm part is stored in the handle body, the power supply is turned inside the flange-shaped part by the switch rod. When the arm is pulled out from the inside of the handle body, the power comes into contact with the bottom of the inside of the flange-shaped part to turn on the light bulb, turning it off when the arm is pulled out of the handle body. The above purpose can be achieved by an oral endoscope.

[0012]

[Embodiment of the invention]

 The oral endoscope according to the present invention has, as its basic components, a handle 1, an arm 2 inserted in the handle 1 so as to be housed or pulled out, and a mirror provided at one end of the arm 2 via a mirror mounting body 31. 3 comprises an oral endoscope removably attached thereto. FIG. 1 is a diagram showing a basic configuration of a state in which the arm body 2 of the present invention is housed in a handle 1 main body. A flange 23 of the arm 2 is in contact with one end of the handle 1 main body, and a mirror 3 via a mirror mounting body 31 is attached to a protrusion 25 following the flange 23. A mirror 3 is provided at the tip of a rod-shaped mirror connecting portion 32 projecting from the mirror mounting body 31, and the mirror 3 is mounted at a predetermined elevation angle. The mirror mounting body 31 has an inserted part having a cylindrical cavity in the figure, and a cylindrical protruding part 25 forming one end of the arm 2 is inserted into the cylindrical inserted part. The mirror mount 31 can be detachably mounted on the mirror. A light source 28 made of a small light bulb is provided at the tip of the protruding portion 25 on the mirror side. At the other end of the handle 1 configured as described above, a clip portion 16 locked by a screw 15 is provided.

Next, FIG. 2 is a view showing a state where the arm body 2 is pulled out from the oral endoscope in a state where the arm body 2 shown in FIG. 1 is housed. The arm body 21 is exposed by pulling out the arm body 2 from the handle 1 main body. Therefore, the columnar flange-shaped portion 23 connected to the arm portion 21 is located farther from one end of the handle 1. The mirror 3 is attached to the protruding portion 25 at one end of the arm body 2 via a mirror attachment body 31 at a predetermined elevation angle. In addition, a light source 28 is provided at the tip of the protruding portion 25.

With the above configuration, as shown in FIG. 2, the distance between the part held by hand and the part of the mirror 3 can be increased by pulling out the arm body 2 during use, and only the near side in the oral cavity is used. Rather, it is extremely easy to see the back of the oral cavity, such as the back teeth and throat. Further, since a light bulb is provided at the tip of the arm body 2, the light source 28 can be obtained in the vicinity of the affected part in the oral cavity. On the other hand, as shown in FIG. 1, by storing the arm body 2 in the main body of the handle 1 during storage and transportation, the oral endoscope can be extremely shortened and the mirror mounting body 31 can be removed. In this figure, the arm body 2 displays a state in which only one arm is provided. However, the present invention is not limited to this, and two or three or more arms may be used. In this case, two or more arms may be sequentially provided concentrically in the handle 1 body, and these may be pulled out to form a long arm body 2. With such a configuration, the present oral endoscope can be configured to be shorter and more compact.

Next, FIG. 3 shows that the light source 28 can be turned on when the arm 2 is pulled out, and the light source 28 can be turned off when the arm 2 is stored. FIG. 2 is a cross-sectional view showing the structure of the embodiment, and is a cross-sectional view in a state where the drawing is performed. A cover 14 made of a soft resin is provided on the outer peripheral surface of the handle 1 body. As a result, the hand feeling can be improved, and the design can be appropriately performed. The handle 1 body has a substantially cylindrical shape having a hollow shape having a bottom portion 12, and a protrusion 13 is provided at an upper portion of the inner circumferential surface of the handle 1 body. The arm portion 21 of the arm body 2 is inserted into such a hollow shape in the handle 1 body.

The arm body 2 includes an arm portion 21 inserted into the handle 1 main body so as to be retractable and retractable, a flange portion 23 connected to the arm portion 21, and a mirror 3 having a predetermined elevation angle. And a projection 25 into which a mirror mounting body 31 having a projection can be inserted. A small light bulb 28 is disposed at the tip of the projection 25. A projection 211 is provided at an outer peripheral end of the arm 2 located in the handle 1 of such an arm 2. Therefore, when the arm 2 is pulled out from the inside of the handle 1 main body, the protrusion 211 of the arm 21 and the protrusion 13 on the inner peripheral surface of the inside of the handle 1 main body are caught, and the pulling out of the arm 2 can be restricted to a certain extent or more. . The protrusions 13 and 211 may be configured as long as they are hooked and prevent the arm 2 from being pulled out. For example, the protrusions 13 and 211 may be formed in a flange shape.

Next, a cavity 212 is provided in the arm portion 21 of the arm body 2 at the axial center thereof, and the interior of the cavity 212 extends from the bottom 12 axis of the handle 1 main body to the opening of the handle 1 main body. A switch rod 17 disposed facing the rear end is inserted. The switch rod 17 is made of an insulating member. The switch rod 17 has a length up to a position where the switch rod 17 is slightly protruded from the inside of the cavity 212 of the arm part 21 with the arm part 21 housed in the handle 1 body. The flange portion 23 connected to the arm portion 21 has a cavity 232 in which a power source such as a battery can be inserted. The cavity 232 of the flange portion 23 is connected to the cavity 212 of the arm portion 21, and the collar portion 23 is made of a conductive member. A projecting portion 25 is continuously provided on such a flange-shaped portion 23, and a light bulb 28 is provided at the tip of the projecting portion 25. The projecting portion 25 is also made of a conductive member.

One of the light bulbs 28 is connected to the built-in power supply 5 via a conductive member, for example, a conductive wire 281, and the other one 282 is a protruding portion 25 made of a conductive member and a flange portion 23. Is connected to the built-in power supply 5 via the. In this case, conduction through the protruding portion 25 made of a conductive member and the flange portion 23 is brought into conduction by contact with the bottom portion 233 inside the flange portion 23. Therefore, except for the bottom portion 233 necessary for this conduction, for example, an insulating member may be provided on the inner peripheral surface 234 of the inside of the cavity 232 of the flange portion 23 or the like. This can prevent unnecessary conduction due to a difference in the shape of the power supply 5 or the like. With this configuration, when the arm portion 21 is pulled out from the inside of the handle 1 main body, the switch rod 17 does not protrude into the internal cavity 232 of the flange-shaped portion 23. Since it comes into contact with the bottom portion 233 inside the flange-shaped portion 23, the conductive state is established. This means that the body can be lengthened by pulling out the arm portion 21 for use, and the inside of the oral cavity can be examined deeply, and the light source 28 can be turned on in the pulled-out state. In some parts, it is possible to illuminate brightly near the affected part.

Next, a mirror mounting body 31 is detachably fitted into the protruding portion 25 of the arm body 2, and the mirror 3 is disposed on the mirror mounting body 31 at an elevation angle. Therefore, the mirror mounting body 31 having the mirror 3 can be replaced one after another, and only the mirror part can be replaced without replacing the main body part in use. For example, it is not only extremely easy to change from a small dental mirror to a large throat mirror, but it is also possible to change the mirror for each patient in terms of hygiene. In addition, the light source 28 will be provided near the base, which is one end of the mirror attachment body 31, that is, near the outer peripheral end of the mirror 3. For example, when examining the affected part, the midpoint between the mirror 3 and the affected part will be provided. It can be irradiated, and the affected area can be illuminated exactly.

Therefore, it is possible to irradiate the vicinity of the affected part from outside the oral cavity without using an extremely expensive medical lighting device as in the related art, thereby facilitating examination and treatment. In addition, it is possible to irradiate the inside of the oral cavity without such a lighting device. For example, it is not necessary to use a conventional flashlight or the like, and it is possible to irradiate the light more closely than a flashlight or the like. Although this figure shows an embodiment of the switch circuit, the present invention is not limited to this, and a switch that conducts when the arm is pulled out and insulates when the arm is inserted may be used. The contact between the protruding portion 13 and the protruding portion 211 may be provided with a switch on the circuit in such a manner that the contact between the protruding portion and the protruding portion 211 is always ensured.

Next, FIG. 4 is a cross-sectional view showing a structure of one embodiment in which the light source 28 can be turned off when the arm body 2 is stored, and is a cross-sectional view in a stored state. The arm portion 21 of the arm body 2 is inserted into the handle 1 body, and is in a housed state. A flange-shaped portion 23 of the arm body 2 is in contact with one end of the handle 1 main body, and suppresses further storage by inserting the arm portion 21. Next, the switch rod 17 extends from the cavity 212 of the arm portion 21 of the arm body 2 to the cavity 232 of the flange portion 23, and slightly protrudes into the cavity 232 of the flange portion 23. The power supply 5 is separated from the bottom portion 233 inside the flange-shaped portion 23 by the protruding portion, and is insulated. Therefore, in this state, no conduction occurs, and the light source 28 does not turn on.

As described above, in the state where the arm portion 21 is housed in the handle 1 main body, the power source 5, for example, a button battery, is separated from the bottom portion 233 inside the flange portion 23 by the switch rod 17, and becomes insulated. Become. On the other hand, when the arm portion 21 is pulled out from the main body of the handle 1, the switch rod 17 no longer protrudes into the internal cavity 232 of the flange-shaped portion 23, and the power source 5, for example, a button battery, contacts the bottom portion 233. Therefore, the conductive state is established. Therefore, when the arm 21 is housed in the main body of the handle 1, the light bulb serving as the light source 28 does not light, and when the arm 21 is pulled out from the main body of the handle 1 for use, the light bulb serving as the light source 28 first turns on. It is. In addition, a spring or the like may be used to ensure the contact between the power source 5, for example, a button battery or the like, and the bottom portion 233 with more elasticity. For example, at the time of conduction between the electric bulb 28 and the power supply 5 via the conductor 281, a spring may be used for the conductor 281 or a spring may be used.

Next, a mirror mounting body 31 is detachably fitted into the protruding portion 25 of the arm body 2, and the mirror 3 is disposed on the mirror mounting body 31 with an elevation angle. Therefore, the mirror mounting body 31 can be removed and stored or carried during storage. In particular, when visiting a large number of patients at the time of a house call, it is possible to hold one body part, and if there are a plurality of these mirror mounts 31, it can be used interchangeably for each patient, which is not only hygienic but also has It is convenient to carry and can be handled with a small amount of equipment. Therefore, it is also very convenient for home medical treatment and the like, which is increasingly needed in the future.

FIG. 5 is an exploded view of the arm body 2. A flange-shaped portion 23 connected to the arm portion 21 of the arm body 2 is screwed at an intermediate portion, and the battery 5 can be inserted into the flange-shaped portion 23. A protruding portion 25 is continuously provided on the upper side of the flange portion 23, and the bulb 28 can be inserted into the cavity 252 of the protruding portion 25. A spring-like conductive wire 281 is connected from the light bulb 28 and is electrically connected to the positive electrode of the battery 5. On the other hand, the other conductive wire 282 contacts and is connected to the inner peripheral surface 254 of the protruding portion 25 and is electrically connected to the protruding portion 25. The conductors of the two 281 and 282 may be insulated by an insulating member. The mirror mounting body 31 having the mirror 3 can be detachably fitted into the projecting portion 25 having such a configuration.
