Description

DETAILED DESCRIPTION OF THE INVENTION The present application relates to a support mechanism for a dental treatment instrument configured to be easily attached to a treatment chair, a part of a treatment table installed in a dental unit, a technician table, etc. In particular, a support mechanism for a dental treatment instrument that is unitized so that a single support function corresponds to a single treatment instrument, and that the unitized member can be increased or decreased or replaced as necessary. 1 is a long cylindrical body with a rectangular cross section and open front and rear ends, and a required number of connectors 2a to 2f are attached to the rear end of the body. An end piece 3 is installed in a sealing manner so as to pass through the cylindrical body 1 in the direction, and a horizontal receiving piece 4 is provided at the front end of the cylinder body 1 so as to extend forward from its lower surface. The inner area has a size that allows a dental treatment instrument to be inserted freely.

Reference numeral 5 denotes a longitudinally long guide hole provided at an intermediate position on the lower surface of the cylindrical body 1, and is formed with a width through which a flexible hose can be freely inserted.

Reference numeral 6 denotes a connecting tool protruding from the rear lower surface of the cylindrical body 1, in which connecting elements connected to each of the connectors 2a to 2f via conductors 7 are installed.

Reference numeral 8 denotes a guide roller 10 which is rotatably attached to the front part of the cylinder body 1 via a support piece 9 in a direction orthogonal to the cylinder body 1;
An actuating plate is attached to the front portion of the cylinder 1 via a support piece 11 so as to be tiltable in the vertical direction, and the front half thereof extends so as to face the receiving piece 4.

Reference numeral 12 denotes a tongue piece 10' projecting from the rear side edge of the actuating plate 10.
An actuation signal element is provided at a position facing the actuating plate 10, and is connected to the opposing connectors 2a to 2f, and the actuating notch 12' normally connects the rear half of the actuating plate 10 The front half is pressed so as to float above the receiving piece 4.

Reference numeral 13 denotes a mounting screw hole, which together constitute a unitized support member A.

Reference numeral B denotes a mounting base for mounting the support member A, which constitutes a part of a treatment table, a technician table, or the like, or constitutes a table dedicated to treatment instruments. This mounting base B is attached to the rear end of a flat plate part 14 having a length suitable for supporting the rear part of the cylinder body 1 and a width multiple times the width of the support member A. An opening 15a is formed in the rear half of the projection 15, and each of the connectors 2 is formed in the front half of the opening 15a.
an insertion hole 16 that faces each of the holes a to 2f and receives the rear end protrusion, and the rear end communicates with the insertion hole 16 and the opening 15a.
Connectors 17 facing inward are respectively provided. The connector 2
a to 2f are for distributing pressurized air for driving the turbine, distributing chip air for fog generation, distributing signal air, and transmitting air signals. The dental treatment instruments supported by the support member A of the present application are classified into those for distributing water for mist generation, and those for energizing heaters, etc., and the dental treatment instruments supported by the support member A of the present application are When it is a hand piece, it has a first connector 2a for turbine drive and a second connector 2a for tip air.
A connector 2b, a third connector 2c for signal air, a fourth connector 2d for air signal, and a fifth connector 2e for water are used, and the treatment instrument is a hand for driving a micromotor. When the treatment instrument is a piece, the second, third, fourth, and fifth connectors 2b to 2e and the sixth connector 2f for energization are used, and when the treatment instrument is a dental sealing, The second, third, fourth, and fifth connectors 2b to 2e described above and the sixth connector 2f for energizing the heater circuit are used. A conductor box 18 containing conductors for connecting each connector 17 to an external device is disposed within the opening 15a. 19 is support member A
This is a set screw for fixing the mount on the mounting base B.

C is a dental treatment instrument to which a flexible hose 20 is connected, and as is well known, a tube or electric wire cord for circulating the required fluid is housed in the flexible hose 20. After the end of the flexible hose 20 is connected to the connector 6, it hangs down in a U-shape, and the operating plate 1 is arranged so that the end of the dental treatment instrument C connected to the end thereof protrudes from the receiving piece 4.
0, and its load pushes up the actuating notch 12'' and puts the actuating signal element in an inoperative state.When the actuating signal element 12 consists of an air valve, the fluid For example, the control device disclosed in Japanese Patent Application Laid-open No. Sho M-528% is adopted.

That is, as shown in FIG. 5, when the treatment instrument is held in the hand and pulled forward from the state where the actuation signal element 12 is closed, the actuation signal element 12 opens and the air signal is transmitted to the fourth connector 2d. This air signal causes the pressurized air operation valve and the water operation valve of the fluid control apparatus to open, and the pressurized air from the pressurized air supply source is sent to the first connector 2.
a and the second connector 2b, and water from a water supply source will be supplied to the fifth connector 2)e, respectively. Further, pressurized air and electric current are supplied to the third connector 2c and the sixth connector 2f by operating a foot switch. Therefore, only the therapeutic instrument held in hand functions seriously by means of the activation signal element 12.

Note that when the fluid control device is constituted by an electrically actuated circuit, a switching element is used as the actuating signal element 12.

FIG. 4 shows that three support members A1 to A8 are arranged on a part of a treatment table D, and a hand piece C1 for driving an air turbine is attached to the first support member A, and a micromotor is attached to the second support members. A configuration example is shown in which a driving hand piece C2 is equipped with a dental syringe C on the third support member.

Therefore, according to the present application, by equipping a single support member with a single dental treatment instrument, it is possible to easily increase or decrease the number of dental treatment instruments or replace different dental treatment instruments according to demand. This is not only convenient for manufacturing tables equipped with dental treatment instruments, but also enables the addition, reduction, or replacement of treatment instruments without involving other support members, making it easy to increase, decrease, or replace the treatment instruments. It is convenient and has the advantage that the supporting members can be arranged neatly on the flat plate part of the mounting base, and the appearance is good.
