DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holder for holding a dental mirror which is inserted into an oral cavity to observe a state of a periodontium in the oral cavity in dental treatment.

[0002]

2. Description of the Related Art In dental treatment, a mirror is used to observe the state of the oral cavity. As shown in FIG. 2, this mirror has a grip 1 attached to a mirror 1 so that an operator can use the mirror. , With this grip, insert the mirror 1 into the oral cavity,
For example, the state of the periodontal is observed. This mirror, of course, must be disinfected for each patient,
Use autoclaved. Therefore, when performing a child screening or the like at a school or the like, a large number of sterilized mirrors are prepared, and these are sequentially used for each child to perform a screening.

[0003] However, it is difficult to prepare a large number of such mirrors from the viewpoint of medication, and in order to autoclave such a large number of mirrors (high-temperature steam sterilization), a large autoclave is required. It required equipment (high-temperature steam sterilizer) and was uneconomical.

In order to solve the above-mentioned inconvenience, as shown in FIG. 3, a mirror 3 is provided with a handle 3, and this handle 3 is detachably mounted on a chuck portion 4a provided at the tip of a holder 4. There has been proposed a mirror 1 having the handle 3 and being autoclaved.
However, in this case, when the handle 3 of the mirror 1 is mounted on the holder 4 and when the mounted mirror is removed from the holder, the surgeon must always hold the handle 3 of the mirror. Would have to put the handle that he touched into the oral cavity, or the surgeon would have to touch the handle that was placed in the oral cavity, in any case unsanitary.

In order to solve the above-mentioned inconveniences, the present applicant has previously made it possible to mount the mirror handle on the holder without touching the handle of the mirror, or to remove the mounted handle. A dental mirror holder was proposed, which made it possible to remove the used mirror from the holder or attach a disinfected mirror to the holder without the operator's hand touching the handle of the mirror.

FIG. 4 is a view for explaining an example of a dental mirror holder proposed by the applicant earlier.
Is a mirror, 11 is a handle of the mirror 10, and 12 is an annular groove provided around the handle. Reference numeral 20 denotes a holder for holding the handle 11 of the mirror, and the surgeon holds the mirror in the holder 20, puts the mirror 10 into the oral cavity while holding the holder 20, and
For example, periodontal observation is performed.

[0007] The hand holder 20 has a hole 21 at the tip end into which the handle 11 of the mirror is inserted, and a spring 22 is provided in the hole 21. Further, a through hole 23 reaching the hole 21 is provided on the outer periphery of the hand holder 20, and a sphere 24 is partially projected into the hole 21 from the hole 23 in the through hole 23. It is provided as follows. Further, on the outer periphery of the hand holder 20, an operation lever 25 for regulating the position of the sphere 24 is provided.
The operation lever 25 is normally pressed in the direction of arrow A by a spring 26.

In FIG. 4, when the handle 11 of the mirror 10 is inserted into the hole 21 with the operating lever 25 moved in the direction of arrow B against the spring 26, the sphere 24 becomes
The handle 11 can be inserted into the hole 21 against the spring 22 because it can move in the direction. When the force applied to the operation lever 25 is removed at the time when the tip of the handle 11 passes under the sphere 24, the sphere 24 falls into the groove 12 when the groove 12 of the handle 11 comes under the sphere 24, and the handle 11 Is fixed in that position. Therefore, the surgeon can insert the mirror 10 into the oral cavity while holding the holder 20 in his / her hand and observe the inside of the oral cavity.

When the operation lever 25 is moved in the direction of arrow B after the observation is completed, the sphere 24 becomes movable in the direction of arrow C, so that the engagement between the sphere 24 and the groove 12 is released, and the handle 11 is pushed back by the spring 22. Then, the mirror 10 jumps out of the holder 20 with the force of the spring 22.

According to the above-described use example, the used mirror 10 can be easily removed from the holder 20 only by operating the operation lever 25 to remove the used mirror 10 from the holder 20. Is very hygienic for the surgeon since he does not touch the mirror after use. However, when attaching the mirror 10 to the holder 20, the surgeon holds the handle 11 of the mirror 10 and inserts it into the hole 21 of the holder 20. It is not necessarily sanitary because it can be put inside.

FIG. 5 is a view for explaining an example in which the above point is taken into consideration, that is, the mirror can be mounted on the holder 20 without the operator touching the mirror. In the figure, reference numeral 30 denotes a mirror stand.
In FIG. 0, a large number of mirrors 10 are arranged side by side with a handle 11 facing upward, as shown in the figure. Therefore, the surgeon operates the operation lever 25 as described above, that is, moves the operation lever 25 in the direction of arrow A, inserts the handle 11 of the mirror 10 into the hole 21 of the holder 20, and When the whole is pushed down, the sphere 24 and the groove 12 are engaged as described above, and the mirror 10 is moved to the holder 2.
0 can be attached.

Although FIG. 5 shows an example in which the mirrors 10 are arranged side by side, it is naturally possible to arrange the mirrors side by side or diagonally. In short, the mirrors are detachably fixed and fixed. Any shape and structure may be used as long as the holder can be mounted.

As shown in FIG. 5, if a large number of mirrors can be fixed at the same time, the used mirrors can be autoclaved (high-temperature steam sterilization).
The autoclave can be autoclaved with a large number of mirrors attached to the mirror stand, and when the autoclaved mirror is taken out of the autoclave, it is sufficient to take out each mirror stand. Moreover, when removing the used mirror from the holder, prepare an empty mirror stand of the same structure and return the used mirror to this empty mirror stand in order, so that the assistant is also used It is very hygienic without having to touch the mirror.
