Description

DETAILED DESCRIPTION OF THE INVENTION The present application relates to a support mechanism for a dental treatment instrument that is configured to be easily attached to a treatment chair, a part of a treatment table installed in a dental unit, a technician table, etc. be.

Conventionally, a plurality of flying arms are arranged in parallel at the rear of a table on which dental instruments are placed via restoring means, and each flying arm has a handpiece for driving an air turbine or a handpiece for driving a micromotor at the tip. Alternatively, a flexible hose connected to a dental treatment instrument such as a syringe is supported, the rear end is connected to a fluid control device installed in a treatment chair or a dental unit, and the treatment instrument is placed on a table. Support for a dental treatment instrument configured to guide the treatment instrument into the oral cavity by gripping the treatment instrument when in use and pulling it forward to tilt the flying arm forward against restoring means. The apparatus is known, for example, from Japanese Utility Model Publications No. 51-45189 to No. 8-35994.

However, conventionally known support devices all have a plurality of treatment instruments and a table on which they are placed, which are integrated, and therefore the number of treatment instruments can be increased or decreased, or different treatment instruments can be replaced, depending on the user's requirements. The flaw was that it was cumbersome to operate and lacked versatility. Therefore, the present application proposes a dental treatment instrument that is unitized so that a single support mechanism corresponds to a single treatment instrument, and that this unitized part can be increased or decreased or replaced as necessary. It provides a support mechanism, and its embodiment will be described in detail below with reference to the drawings. 1 is a long housing with a rectangular cross section and an open rear end, and a required number of connectors 2a to 2f are attached to the rear end. An end piece 3 is attached in a sealed manner so as to penetrate through it in the thickness direction.

4 is a flying arm in which the upper end 4a of a hollow tube is curved in an inverted U shape, and its outer circumferential surface is open; The flying arm 4 is pivoted and can be tilted within the range of a guide hole 6 formed in the upper surface of the housing 1 and extending in the longitudinal direction.

The flying arm 4 is normally biased by a spring 8 attached between its lower end and a support piece 7 provided within the housing 1 so as to tilt rearward. Reference numeral 9 indicates a set screw 1 on the inclined surface 1'' formed on the upper surface of the top end of the housing 1.
This is a mounting piece that is fixed by a 0 and is formed in a curved shape so as to receive a treatment instrument.

Reference numeral 11 denotes an actuation signal element that is activated when the flying arm 4 is tilted from a rearward tilted state to a forwardly tilted state, and is composed of, for example, an air valve. Although not shown, when this air valve 11 is activated to generate an air signal. For example, a fluid control system installed within the treatment chair or dental unit is activated to supply the treatment instrument with pressurized air, water, or other fluids necessary to make the treatment instrument function.

Reference numeral 12 denotes a screw hole for mounting, and the support member A is constituted by the above.

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 the flat plate portion 13 having a length approximately equal to that of the housing 1 and a width multiple times the width of the supporting member A.
Toho (It has a protrusion 14 of equal height, and an opening 14a is formed in the rear half of the protrusion 14, and each of the connectors 2a to 2f is formed in the front half of the protrusion 14. and an insertion hole 15 that faces each other and receives the rear end protrusion, and a connector 16 communicating with the insertion hole 15 whose rear end faces into the opening 14.a.The connectors 2a to 2f are , for circulating pressurized air for driving the turbine;
One for distributing chip air for fog generation, one for distributing signal air, and one for sending air signals. They are divided into those for distributing water for fog generation, and those for energizing heaters, etc.
When the dental treatment instrument supported by the support member of the present application is a hand piece for driving an air turbine, the first connector 2a for driving the turbine and the second connector 2b for tip-air.
, the third connector 2c for signal air, and the fourth connector 2c for air signal.
A connector 2d and a fifth connector 2e for water are used, and when the treatment instrument is a micromotor-driven handpiece, the second, third, fourth, and fifth connectors are used. 2b
2e to 2e and a sixth connector 2f for energization are used, and if the treatment instrument is a dental syringe, the second, third, fourth, and fifth connectors 2b to 2e and the heater circuit are used. The sixth connector 2f for energization will be used.
Inside the opening 14a, a conductor box 1 is provided with a conductor for connecting each connector 16 to an external device.
1 is placed. 12'' is a set screw for fixing the support member A on the mounting base B.

Reference numeral C denotes a dental treatment instrument to which a flexible hose 18 is connected, and as is well known, a tube or electric wire cord 1' is housed in the flexible hose 18 for circulating the required fluid. After the flexible hose 18 is inserted into the flying arm 4, the tubes or electric wire cords housed in the hose are connected to the corresponding connectors 2a to 2f at the ends thereof, and the flexible hose 18 is inserted into the flying arm 4. 18 is led out from the upper end curved portion 4a of the flying arm 14, and then the treatment instrument C is placed on the mounting piece 9. In the case of the actuation signal element 11 consisting of an air valve, a fluid control device such as that disclosed in, for example, Japanese Patent Application Laid-Open No. 52896/1986 is applied.

That is, when the actuation signal element 11 is actuated by the flying arm 4, an air signal is sent to the fluid control device via the fourth connector 2d, and the input of this air signal causes the pressurized air operation valve and the water The pressurized air from the pressurized air supply source is supplied to the first connector 2a1 and the second
Water from the water supply source is supplied to the connector 2b, and water from the water supply source is supplied to the fifth connector 2e. Also, the third connector 2c
Pressurized air and current are supplied to the sixth connector 2f by operating a foot switch. Therefore, only the treatment instrument supported by the tilted flying arm 4 is activated by the activation signal element 1.
1 will function for the first time.

Note that when the fluid control device is constituted by an electrically actuated circuit, a switching element is used as the actuation signal element 11.

FIG. 4 shows that three support members A1 to ~ are arranged on a part of the treatment table D, and the first support member A1 is equipped with a hand piece C1 for driving an air turbine, and the second support member ~ is driven by a micromotor. A configuration example is shown in which a dental syringe C3 is provided on the third support member and a dental syringe C3, respectively.

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. Not only is it convenient for manufacturing tables equipped with dental treatment instruments, but it is also convenient for increasing, decreasing, or replacing treatment instruments because it can be done independently of other supporting members. Moreover, it has the advantage that the supporting members can be arranged in an orderly manner on the flat plate part of the mounting base, and the appearance is good.
