[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an external view of a main part for explaining an embodiment of a dental treatment chair according to the present invention.
Numeral 1 denotes a dental treatment chair, which performs up and down movement, inversion activation, tilting movement and the like, similarly to the dental treatment chair shown in FIG. Reference numeral 10 denotes an auxiliary table (side table) added according to the present invention. The auxiliary table 10 extends laterally from the rear of the treatment chair 1 and has a pin 12 so as to be rotatable.

The arm 11 is normally pushed in the direction of the arrow A and is hidden behind the treatment chair 1, and does not affect the vertical movement of the chair, the tilting movement, the tilting movement, etc., and the rear of the treatment chair 1 is not affected. It is stored in. At the time of dental treatment, as is well known, the treatment chair is collapsed to perform root canal enlargement and other dental treatments according to the symptoms. At that time, frequently used drugs, tweezers, scissors, mirrors, etc. The auxiliary table 10 is very easy to work with the various operation switches of the dental treatment unit and the operation switches of the instruments at hand.
In use, as is well known, the auxiliary table 10 is pulled out laterally from the rear of the chair 1 to be in a horizontal state (the arm 11 and the support for supporting the arm 11). The member is rotatable by well-known means, and the arm 11 can be fixed at any desired rotation position with respect to the arm support member). Place parts temporarily,
Further, an apex position detecting device is attached to the auxiliary table 10 so that a root canal enlarging operation frequently performed in dental treatment can be performed more efficiently.

FIG. 2 is a configuration diagram of a main part for explaining an example of an apex position detecting device. In the figure, reference numeral 13 denotes an apex position (or root canal length) measurement file, and reference numeral 20 denotes an apical position (or root). The tooth whose tube length is to be measured, 21 is a root canal, 14 is a stopper, 15 is a lip, 16 is a measurement electrode terminal, 17 is a counter electrode terminal, and 18 is a lead wire for a measurement electrode terminal communicating with the measurement electrode terminal 16. , 19 are a counter electrode terminal lead wire communicating with the counter electrode 17 hooked on the lip 15, 30 is an apex position measuring device main body to which these leads 18 and 19 are connected,
Reference numeral 31 denotes an apex hole position detection display, which is a known apical position detection display when the file 11 is inserted into the root canal 21 with the measurement electrode terminal 16 in contact with the file 13. Knowing that the tip of the file 13 has reached the apical position from the pointer position of the part 31, in that state, the stopper 14 is moved to a position where it hits the tooth 20 and taken out of the oral cavity. However, when the tip of the file 13 approaches the apical position, the pointer of the apical position detection display unit 31 starts to swing, so that it is known that the file tip 13 has approached the apical position. (Note that as a method for electrically detecting the apical foramen position, a large number of publications have been published, including Japanese Patent Publication No. 62-2187, and the details thereof will be omitted. ).

In FIG. 1, reference numeral 30 denotes an apex position measuring device as described above. The apical position measuring device 30 is provided integrally with the auxiliary table 10, and preferably, a shaft 32 is attached to the auxiliary table 10. Is mounted so as to be rotatable around the center, and at the time of use, the pointer is set at a desired angle so that the pointer can be easily seen. Also in this case, the rotation shaft 32 can be held at a desired rotation position by any desired known means. Reference numeral 40 denotes a winding means for winding the above-mentioned lead wire 18 for the electrode terminal for measurement and the lead wire 19 for the counter electrode terminal, and these lead wires are normally wound by the winding means 40. It is stored in the auxiliary table 10.

However, since the measuring electrode terminal 16, the counter electrode terminal 17 and the like are used in the patient's mouth, it is necessary to replace the sterilized one for each patient and use it. Lead wire wound by the winding device 40 (lead wire for measuring electrode and lead wire for counter electrode)
41 and the lead wires 42 connected to the lead wire 18 for the measurement electrode terminal and the lead wire 19 for the counter electrode terminal can be separated by connection jacks 43 and 44, and the connection jack 43 hits the end face of the auxiliary table 10. If it is prevented from being taken up any more, the measurement electrode terminal lead wire 18 and the counter electrode terminal lead wire 19 can be separated from the lead wire 41 by one lead wire 42,
The autoclave or the like can be sterilized. At this time, the lead wire for the measurement electrode terminal and the lead wire 19 for the counter electrode terminal are connected to the integrated lead wire 42, so that these lead wires are separated and lost. It is very easy to work in an autoclave.

[0015]

As is apparent from the above description, according to the present invention, since the auxiliary table is arranged near the operation during the operation, parts frequently used during the treatment can be placed on the auxiliary table. Because it can be placed temporarily, the procedure is very easy and the work efficiency is improved. Further, since the apical position detecting device used for the root canal enlargement operation is integrally attached to the auxiliary table, the root canal enlargement operation can be performed more efficiently.
