[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a holder that is attached to the side of a dental treatment table or the like and is used to hold various instruments used in dental treatment.

(Prior Art) It is well known that various instruments such as handpieces and syringes are used in dental treatment. These instruments are
It is connected to a flexible hose containing a built-in conduit for supplying working media such as water, air, and electricity, and is held in a holder installed on the dental treatment table itself or its side. The instrument is appropriately removed from this holder and used for treatment. Among these, the holders installed on the side of the treatment table, etc.
Examples include a hanger type that hangs the grip part of the instrument, and a type that is inserted and held from the tip of the instrument into a holding hole formed to match the shape of the instrument. It will be done.

(Problem to be solved by the invention) However, in the case of the above-mentioned holder in which the instrument is inserted and held in the holding hole, the holding hole is formed in a shape that matches the external shape of the various instruments. It is impossible to hold different types of instruments in the same holding hole. Therefore, in dental treatment where several types of instruments are handled in a short period of time, the mental hassle of correctly fitting the instruments into the corresponding holding holes is extremely great, and sometimes the smooth treatment is impaired. It was hot too. Additionally, depending on the treatment, the instrument already connected to the flexible hose may be replaced with a different type of instrument, but in such cases, the holder may no longer be able to hold the instrument. There have been many cases.

The present invention has been developed in view of the above, and it is an object of the present invention to provide a new dental instrument holder that can loosely insert and hold any type of instrument.

(Means for Solving the Problems) The structure of the dental instrument holder of the present invention for achieving the above object will be explained based on embodiment drawings. Fig. 1 is a partially cutaway perspective view showing an embodiment of the holder of the present invention, Fig. 2 is an exploded perspective view of the holder of the same embodiment as seen from the back, and Fig. 3 is an enlarged vertical cross-sectional view of the portion shown in Fig. 1 - the lined section. , FIG. 4 is a diagram similar to FIG. 3 of another embodiment, and FIG. 5 is a diagram similar to FIG. 3 of still another embodiment. That is, the instrument holder of the present invention includes a holder main body 1, a plurality of holding holes 2 arranged in parallel on the main body 1 and having openings at both ends and capable of loosely inserting and holding dental instruments from the distal end thereof, and the holding holes 2. The main feature is that a stop member 3 is provided on the inner surface of the hole 2 so as to be able to adjust its position along its longitudinal direction.

Although FIG. 1 shows an example in which a handpiece is held as an instrument, it is also possible to hold a vacuum syringe, a three-way syringe, or the like. Therefore, the cross-sectional shape of the holding hole 2 is designed to allow several types of instruments to be inserted loosely therein, especially in the case of a contra handpiece in which the tip tool is oriented perpendicular to the axial direction as shown in the figure.
It is desirable that the tool be shaped into an oblong rectangle or an ellipse so that the tool can be inserted freely without getting in the way.
The cross-sectional shape of the holding hole 2 in the figure consists of a large-diameter portion 21 into which the grip portion of the handpiece can be loosely inserted, and a small-diameter portion 22 into which the tool can be inserted, and the cross-sectional shape of the holding hole 2 is substantially in the shape of a horizontally long rectangle. There is.
In addition, in the figure, the large-diameter portion 21 and the small-diameter portion 22 of the adjacent holding holes 2, 2 are partially in communication, and the narrowed portion due to the small-diameter portion 22 is the portion of the adjacent holding hole 2, 2. It is considered a demarcated area. Such a holding hole 2
are formed penetratingly between the upper and lower side surfaces of the holder body 1, that is, with both ends open, and parallel to each other in the width direction of the body 1.

The holder body 1 is desirably made of a material obtained by injection molding of a hard synthetic resin having excellent chemical resistance and heat resistance. This is to prevent damage to the grip, the above-mentioned tools, flexible hoses, etc. due to impact when inserting and removing instruments, or
This is to enable boiling water disinfection or chemical treatment to prevent secondary infection of infectious diseases such as hepatitis or AIDS. Furthermore, the holder main body 1 can be divided into a front cover part 11 and a rear substrate part 12 as shown in FIG. 2, so that the inner surface of the holding hole 2, etc. can be easily cleaned and disinfected. The metal protrusions 111 semi-embedded in the dividing surface of the front cover part 11 are connected to the rear substrate part 1.
This hole 121 is inserted into the hole 121 recessed in the dividing surface of No. 2 to maintain alignment between the front cover portion 11 and the rear substrate 12. Further, the holder is attached to the back of the back seat of a dental treatment table, and the groove 122 formed on the back of the back substrate 12 and the groove 112 formed on the lower side of the front cover 11 are attached to the back of the back seat. It is used to lock onto metal fittings etc. that are fixed to the.

Furthermore, the retaining hole 2 is provided with a stop member 3 as shown in an embodiment to be described later, the position of which can be adjusted in the longitudinal direction, so that the depth of the retaining hole 2 can be adjusted.

(Function) In the instrument holder configured as described above, any type of instrument can be loosely inserted into each holding hole 2 from its tip, and a stopper member 3 is provided in the holding hole 2. Because of this, the instrument is received by this stopper member 3 and stably held without falling off. In addition, this stop member 3 is installed so that its position can be adjusted freely along the longitudinal direction of the holding hole 2, so if the position is set in advance according to the type of instrument, it is possible to adjust the position of the stop member 3 in a short manner. Even if it is an instrument, it does not get stuck excessively, and the operator can always grasp the grip part correctly and perform treatment.

(Example) Next, an example will be described. 3 to 5 show various examples of modifications of the stop member 3.
The abutment member 3 in the figure has an O-ring 31 in its peripheral groove.
This O-ring 31 is brought into pressure contact with the inner wall surface of the holding hole 2, and the corresponding locking member 3 is locked in an arbitrary position by its friction action. To lock the corresponding locking member 3 in a desired position, it can be easily done by pushing an appropriate rod-shaped object through the openings at both ends of the holding hole 2. is a stopper for preventing the stop member 3 from falling off.

In addition, the abutment member 3 in FIG.
A recess 24 for receiving the engaging member 32 is provided on the inner wall of the recess 24 .
... are recessed at intervals along its longitudinal direction,
By elastically fitting the engaging elements 32 into the recesses 24, the abutting member 3 can be locked at any desired position. In this case, the stopper member 3 can be locked at any position by pushing it in with a suitable rod-shaped object as described above, and the small protrusion 23 protruding from the inner surface of the lower part of the holding hole 2 prevents it from falling off. Although the small protrusion 23 has the function of a stopper as described above, it is not limited to this, and for example, the small protrusion 23 has the function of a stopper.
This can also be achieved by reducing the diameter of the lower part in steps.

The stop member 3 in FIG. 5 has a bolt/nut 34,
35 is fixedly installed, and on the other hand, an elongated hole 25 is bored in the wall surface of the holding hole 2 along its longitudinal direction, and the elongated hole 25
The bolt 34 is inserted into the bolt 34, and a nut (wing nut, etc.) 3 is inserted into the bolt 34 from the outside of the holder body 1.
By screwing 5, it is possible to lock the stopper member 3 at any position.

Note that the shapes of the holder body 1, holding hole 2, etc. are not limited to those shown in the figures. It goes without saying that other changes may be made without departing from the invention.

(Effects of the invention) As mentioned above, the dental instrument holder of the present invention is capable of loosely inserting and holding any type of instrument into its holding hole 2.
Even when the operator uses several types of instruments in a short period of time, the operator can properly hold them in any one of the holding holes 2, and there is no mental trouble associated with the conventional method. Further, since the retaining hole 2 is provided with a stopper member 3, when an instrument is loosely inserted, the instrument is received and stably held without falling off. Furthermore, since the corresponding locking member 3 can be locked in a position adjustable manner along the longitudinal direction of the holding hole 2, if the position is adjusted in advance according to the type of instrument, the length and length of the grip can be adjusted. Regardless of the situation, the surgeon can always grasp the grip portion correctly and perform treatment.
The instrument holder of the present invention has many advantages as described above, and its practicality is extremely high.
