However, this autopsy device has the disadvantage that the distance from the handle body to the endoscope can only be shortened within the range of movement of the adjustment member, making it difficult to downsize the device for storage. The purpose of this invention is to eliminate the drawbacks of the conventional devices mentioned above, and to provide an oral cavity examination device that can shorten the distance between the handle body and the endoscope when not in use, can be made compact, and is convenient for storage. That is.

In order to achieve the above object, the present invention includes a cylindrical handle main body having an annular groove in the upper part, a support member fitted to the handle main body at a lower part so as to be rotatable and vertically movable, and an upper end of the support member. an endoscope pivotably supported vertically via a first horizontal axis; and a connecting member disposed along the supporting member between the supporting member and the handle body, the connecting member being disposed between the supporting member and the handle body. The upper portion of the member defines a second horizontal axis parallel to the first horizontal axis, the second horizontal axis slidably pivoting on the endoscope parallel to its mirror surface and perpendicular to the second horizontal axis. The lower part of the connecting member is provided with a bent part, and this bent part is slidably accommodated in a long groove extending in the vertical direction provided at the lower part of the supporting member, and the lower end of the connecting member is placed outside the long groove. It is characterized in that it protrudes and fits into the annular groove of the handle body so that it can be engaged and detached and slidably moved.

An embodiment of the present invention will be specifically described based on the drawings. In FIG. 1, 10 is a lighting device, which is the same as a commercially available pencil type light. Structurally, it is more preferable that it is water resistant.

An outer cylinder 14 containing a light bulb 11 is screw-fitted into a battery housing cylinder 12 housing a battery therein.

A rotary switch 13 is located at the lower end of the battery storage cylinder 12.
exists. An annular spacing groove 1 is provided at the upper end of the pipe 15 that accommodates the battery storage cylinder 12 and constitutes the handle body.
6. Annular storage groove 17 and stopper 1 in the middle part
9. Horizontal holes 18, 18' for switch operation are provided at the lower end.
exists.

In FIGS. 1 and 2, a remote control sleeve 57 integral with the support shaft 5 constituting the support member is attached to the pipe 15.
are smoothly fitted so that they can rotate and move up and down on the pipe 15. The outer diameter part of the lower half of the remote control sleeve 57 is designed to prevent the hand from slipping and make it easier to operate.
It is formed on an uneven surface.

The concave groove hinges 22, 22' of the endoscope 2 are fitted into the convex hinge 51 of the support shaft 5 so as to be swingable by means of a pin 52 constituting a first horizontal shaft.

A rod 60, which is a connecting member for swinging the endoscope 2 by the vertical movement of the separation sleeve 57, is disposed along the support shaft 5 between the support shaft 5 and the pipe 15, and is located above the rod 60. The tip is the 10th and 1st
As shown in FIG. 1, the rod fly 62 is bent horizontally to form a rod slide 62, that is, a second horizontal axis, and the rod fly 62 is inserted into the slide groove 21 on the back side of the endoscope holder 24, parallel to the mirror surface and perpendicular to the axis of the rod slide 62. It is pivoted so that it can slide in the direction.

One end of the rod slide 62 is bent horizontally at a right angle to form a rod arm 61, which is inserted into the longitudinal groove 23 of the holder 24.

One end of the rod arm 61 is bent at a right angle and
Through the hinge groove 55 shown in Figures 0 and 12,
It depends downwardly through a rod groove 53 shown in FIGS. 10 and 13.

The rod 60 is accommodated in a rod groove 53 and an inclined groove 56 formed in the support shaft 5, and a U-shaped bent portion is formed at the bottom thereof, and this bent portion extends from the support shaft 5 to the remote control sleeve 57 in the vertical direction. It is slidably accommodated in a through groove 54 that constitutes a provided long groove. The vertical portion of this bend forms a knob 65 and projects from the through groove 54.

The lower tip of the rod 60 is a horizontal rod end 6
3, the rod end 63 protrudes from the through groove 54 toward the pipe 15, and engages and slides into the spacing groove 16 in FIG. 1 and into the storage groove 17 in FIG. 5, respectively. is possible.

In FIG. 1, due to the presence of the inclined groove 56 and the elasticity of the rod 60, the knob 65 is slightly pulled outward, as shown by the two-dot chain line, to move the rod end 63 out of the spacing groove 16. I can write.

Alternatively, as shown in FIG. 15, the through groove 54 and the knob 6
5 is replaced with a bag groove 58 and a spherical tip 66, and by strongly moving the spacing sleeve 57A upward or downward, the spherical tip 66 at the tip of the rod 60 is automatically bent within the bag groove 58 and the inclined groove 56. Then, it comes off the separation groove 16A. With normal operating force, the tip 66 does not come out of the spacing groove 16A, and the effect is the same even if the tip 66 acts only to swing and rotate the endoscope 2. In this case, the advantage is that the operation of pulling the knob 65 can be omitted. Instead of the spherical tip 66, the tip of the rod 60 may be bent into a U-shape.

When the spacing sleeve 57 is pulled down as far as it will go with the rod end 63 slidingly fitted in the spacing groove 16, the knob 65 will fit into the through groove 54 as shown in FIG.
The rod slide 62 is located above the slide groove 21.
, and the swing angle of the endoscope 2 is the 10th
As shown in the figure, the minimum α min.

Next, raise the remote control sleeve 57 upwards as far as it will go,
As shown in FIG. 8, the knob 65 is located below the through groove 54, the rod slide 62 is located on the left side of the slide groove 21, and the swing angle of the endoscope 2 is at its maximum as shown by the two-dot chain line in FIG. α max.

The distance S in FIG. 8 indicates the vertical stroke of the spacing sleeve 57 required to swing the endoscope 2 from α min. to α max.

Since the rod end 63 is fitted into the spacing groove 16, it cannot move up and down but can rotate.
Therefore, the remote control sleeve 57 can be rotated, so that
This is why the endoscope 2 can also swing and rotate as described above.

As shown in FIGS. 5 and 14, there are small protrusions 64, 64' on both sides of the entrance of the inclined groove 56, and due to their elastic deformation, the rod 60 is bitten into the groove, and the remote control sleeve 57, the support shaft 5, Endoscope 2 and rod 60
The lighting device 1
When separated from zero, that is, in the state shown in FIG. 7, the rod 60 is prevented from slipping out of the rod groove 53 of the support shaft 5.

In FIG. 1, the mirror surface of the extraoral mirror 3 is formed into a concave shape so that the object to be examined can be greatly enlarged and examined in detail. The extraoral mirror 3 is fitted into an extraoral mirror holder 31. On the back side of the holder 31, there is an L-shaped upper arm 33 having an upper ball 32 at its tip.

In FIG. 1, there is a hole 41 on the right side of the base 40.
exists so that the lower end of the pipe 15 can be attached and detached.
It is press-fitted into this hole 41. Alternatively, the same effect can be achieved by screw fitting.

On the left side, there is a lower arm 43 having a lower ball 42 at its tip.

As shown in FIGS. 2 and 4, steps 45, 45' are provided on the left and right sides in the longitudinal direction, and projections 46, 4 are provided at the center of the steps 45, 45'.
6' is formed.

As shown in FIG. 4, when the pipe 15 is held in the hand and the remote control sleeve 57 is operated up and down and rotated, there is a large inclined portion 4 so that the palm fits smoothly.
4,44' are formed.

As shown in FIGS. 1 and 2, two supports 71 and 71' having spherical recesses at both ends are tightened at the center with appropriate pressure by a screw 72 and a dial 7 serving as a nut. A lower ball 42 and an upper ball 32 are held and supported so as to be swingable and rotatable to form a flexible joint 70.

The relationship between the screw 72 and the dial 7 is such that the key-like protrusion of the screw 72 slides into the inner diameter keyway of the dial 7 to transmit rotational force.

Lower ball 43 supporting lower ball 42
The holder 31 has its shaft part horizontally or almost horizontally in the direction of the pipe 15, and then bends downward and is supported by the base 40. It can move freely in any direction and change its posture and position. As shown in FIG. 3, the arm 33 and the ball 3
By providing a rotatable collar 34 between the edges 35 and 2, even when the holder 31 is swung so that the end edge 35 of the support 71 comes into contact with the arm 33, the frictional force between the edge 35 and the arm 33 is reduced. , the rotational frictional force of the collar 34 changes and the holder 3
This has the advantage that posture operation in step 1 is extremely easy.

Other methods of supporting the extra-oral mirror holder 31, such as a flexible tube used in a light stand or a rubber hose with a lead wire inserted inside, will have the same effect.

In FIGS. 16 and 17, 80 is a cover, the upper left corner is recessed, and a hole 82 provided in this recess is into which the lower side of a mirror anti-fogging liquid bottle 90 is press-fitted in a detachable manner. . 91 is the cap of the bottle 90.

Small grooves 81, 81' into which the protrusions 46, 46' of the base 40 are fitted are formed at the lower end of the cover 80 in the longitudinal direction.If the cover 80 is press-fitted from above, the lower end of the cover 80 will be elastically deformed and the protrusions will fit into the small grooves 81, 81'. 46, 46' will snap into place.

When removing the cover 80 from the base 40, use both hands to hold the lower parts of both sides of the cover 80 where the small grooves 81 and 81' are not present, and the small grooves 81 and 81' will be removed.
81' is separated from the protrusions 46, 46'.

Explanation of operation If you put your finger on the horizontal holes 18, 18' of the pipe 15 and turn the switch 13 a little, the switch will turn on and the light bulb 11 inside the outer cylinder 14 will light up.

Grip the pipe 15 and place only your thumb, or your thumb and forefinger, on the spacing sleeve 57. and oral mirror 2
put it in your mouth. Insert it so that the support shaft 5 is approximately perpendicular to your mouth.

Position the mouth mirror 2 near the teeth you want to view,
Rotate the remote control sleeve 57 so that the mirror surface faces the target tooth. At this time, the light from the light bulb 11 goes straight to the oral mirror 2 and brightly illuminates the teeth being viewed through specular reflection.

Adjust the posture and distance of the extraoral mirror holder 3 so that it is reflected in the center of the extraoral mirror 3 at a distance that is easy to see.
Use the hand on the opposite side of step 1 to adjust the swing to the left, right, front, back, up and down.

To adjust the distance, use the holder 3 shown by the solid line in Figure 1.
The position No. 1 is the closest to the eye, and the state of the holder 31 shown in FIG. 3 is the farthest from the eye. The adjustable distance is indicated by distance D in FIG.

Almost in parallel with the above-mentioned operation, the distance control sleeve 57 is moved up and down to adjust the swing angle α of the intraoral mirror 2, so that the surface of the target tooth to be viewed is reflected in the extraoral mirror 3. do.

When looking at the inside of the back teeth, α should be somewhat smaller.
Increase α as you get closer to the front teeth. When looking at the back side of the lower front teeth, raise the sleeve 57 to the top and set α to α max. or an angle close to it. When looking at the back side of the upper front teeth, it is best to set α at around 45°.

By slightly pulling the knob 65 outward, the rod end 63 will be removed from the spacing groove 16, allowing the spacing sleeve 57 and therefore the endoscope portion 50 to be removed from the pipe 15,
Therefore, it can be removed from the lighting device 10.

When installing, there is no need to pull the Nov 65.
Since the upper end surface of the pipe 15 is formed into a conical shape, the force for pushing the knob 65 outward is generated simply by inserting the sleeve 57 into the pipe 15, and the sleeve 57 can be automatically set.

FIG. 6 shows the main body 100 comprised of the illumination device 10 and the extraoral mirror part 30 after the intraoral mirror part 50 shown in FIG. 7 has been separated by the above-described operation.

By using only this main body 100, it is possible to perform a detailed autopsy of the parts that face the eyes, such as the throat, oral cavity, inside of the nostrils, and the eyeballs. That is, by directly illuminating the object with the illumination device 10 and adjusting the position and posture of the extraoral mirror 3, the throat, inner surface of the oral cavity, surfaces of the teeth and gums, the back of the nostrils, the surface of the eyeballs, etc. can be brightly and clearly enlarged. You can see it being done. If you get into the habit of checking with the autopsy device of the present invention on a daily basis, you will be able to discover even minute abnormalities yourself.

As shown in FIG.
Since the main body 100 can be easily attached and detached from the main body 100, when a plurality of people use the main body 100, a plurality of oral endoscope parts 50 can be prepared for hygiene reasons and used while being attached to the main body 100.

Alternatively, it can be used for various purposes, such as a small intraoral mirror 2 installed for small-sized mouths or autopsy in narrow and difficult places, or an extraoral mirror part 50 equipped with an extraoral mirror 2 having a concave mirror surface. The reason is that you can easily change and use the one according to your needs.

The autopsy device of the present invention is capable of inspecting even one's own ear canal. That is, as shown by the two-dot chain line in FIG. 5, the extra-oral mirror holder 31 is extended to the lowest front end so that the distance between the intra-oral mirror 2 and the extra-oral mirror 3 is maximized, and the illumination device 10 is moved forward. After holding the extra-oral mirror part 30 so that it is in front of it, position the oral mirror 2 in front of the ear canal and operate the remote control sleeve 57 to take a closer look at your own ear canal. I can do it.

When attempting to perform an autopsy on another person's oral cavity, base 40
By pulling off the lower end of the pipe 15 that is press-fitted into the hole 41, it separates into two parts: an intraoral mirror-lighting device part 90 as shown in FIG. 8, and an extraoral mirror part 30 as shown in FIG. do.

Holding this endoscope-lighting device part 90 in your hand,
After turning on the illumination device 10, the endoscope 2 is put into the mouth of the subject to perform an autopsy.

If the remote control sleeve 57 is operated in the same way as when performing an autopsy on one's own self as described above, the autopsy can be performed more efficiently and easily than with a conventional fixed dental mirror.

In other words, when looking at the back side of the back teeth, for example, if you try to handle the oral mirror 2 without swinging it like a conventional fixed dental mirror, you will have to open your mouth very wide and move your hands a lot. . Still, it is difficult to see clearly. At this time, by raising the remote control sleeve 57 upward to increase the swing angle of the endoscope 2, it is possible to easily view every corner of the back side of the back teeth while keeping the movement of the hand small.

FIG. 9 shows only the extraoral mirror portion 30. It can also be used as a shaving mirror. It is convenient because you can freely adjust the direction and height of the mirror surface.

FIG. 5 shows a state in which the height of the endoscope-illuminator portion 90 is reduced by a dimension H when not in use.

To reduce the height from the state in use shown in FIGS. 1 and 8, pull the knob 65 slightly outward, remove the rod end 63 from the spacing groove 16, and move the spacing sleeve 57 downward. If you pull it down, sleeve 5
The lower end of the pipe 7 hits a protrusion stopper 19 provided on the pipe 15 and is stopped. In this position, the rod end 63 is inserted into the storage groove 1 provided in the pipe 15.
Fits in 7.

Since the upper part of the storage groove 17 is formed in a tapered shape, in order to set the endoscope part 50 in a state of use, just pull the remote control sleeve 57 upwards with a little strong force, and the rod end 63 will be opened due to the above-mentioned taper. It will automatically come off from the groove 17. When the spacing sleeve 57 is moved upward, the rod end 63 punches into the spacing groove 16 and stops.

To store it when not in use, first reduce the height of the endoscope-lighting device part 90, as shown in FIGS. 16 and 17, and then attach the endoscope holder 31 to the remote control sleeve 57 as shown in the figure. Upper ball 32, upper arm 33, lower ball 42, lower arm 43 so that the back sides of 31 are in tight contact with each other.
and operates the universal joint 70 composed of the supports 71, 71'.

When the cover 80 is placed over the cover 80, the protrusions 46, 46' of the base 40 and the small grooves 81, 81' of the cover 80 fit together, and the cover 80 can be firmly set.

One of the features of the autopsy device of this invention is that it uses a mirror in cases where there is a lot of moisture, such as in the oral cavity.

As a result, the endoscope 2 often appears cloudy and unclear due to humidity.

Therefore, anti-fogging liquid is used where the autopsy equipment is located.
It is an essential condition that it must always be nearby. To this end, as shown in FIG. 14, the cover 80 is formed into an inverted L shape by utilizing the space above the extraoral mirror holder 31, and the anti-fog liquid bottle 90 can be press-fitted into the hole 82 for easy attachment and removal. The structure was designed to do this.

The anti-fogging liquid bottle 90 is just like an eye drop container, and is structured so that by removing the cap 91 and slightly press-fitting the body of the bottle 90, an infusion can be made through the extremely small hole at the tip.

Since the present invention is configured as described above, when the device is not in use, the lower end of the connecting member fitted into the annular groove of the handle body is detached from the annular groove, and in this detached state, the support member is moved along the handle body. By moving the endoscope down, the position of the endoscope can be brought very close to the handle body, which shortens the distance between the handle body and the endoscope, making it more compact and convenient for storage. In addition, by moving the support member upward from the above state, the lower tip of the connecting member is again projected out of the long groove at the bottom of the support member and fitted into the annular groove of the handle body, and the position of the endoscope is adjusted. The handle can be quickly brought into use at a desired distance from the handle body. Moreover, compared to the conventional model, it is not only easier to operate, but also has a simpler structure.
This has the effect of reducing costs and maintaining and improving quality.
