DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foot controller and a control box suitable for use in cooperation with the foot controller. The present invention relates to a selection control of a micro engine used in surgery, dentistry, veterinary surgery, technical labor, jewelry and the like. It is suitable for use.

[0002]

2. Description of the Related Art Micro engine handpieces (instruments) for surgery, dentistry, veterinary surgery, dental technics, jewelry, etc.
Is extremely common. This micro-engine handpiece usually includes a power unit having a built-in electric motor and a handpiece unit detachably mounted on the power unit, and transmits the rotation of the motor in the power unit to a power transmission shaft in the handpiece. Then, the power is transmitted to a cutting tool detachably attached to the chuck mechanism at the tip of the handpiece, and the cutting tool performs a surgical operation or a technique.

A micro-engine handpiece as described above is usually detachably mounted on a control box used by being placed on an operating table or a work table, and is extended from the control box via a cord by a foot controller. Is controlled by foot operation.

However, the conventional control box is
Only a single instrument (micro engine handpiece) can be connected. For example, in jewelry, two types of rotary cutting handpiece and stamping handpiece are often used, but only a conventional single handpiece is used. In the case of a control box that could not be mounted, the handpiece had to be replaced each time, which was extremely inconvenient.
The same applies to surgery, dentistry, veterinary surgery, technical labor, and the like. For example, if two types of handpieces, a high-speed cutting handpiece and a low-speed cutting handpiece, are provided, each time the handpiece is equipped, It is not necessary to change the blade, or if the blades (cutting tools) are different even at the same high speed or the same low speed, there is no need to replace the blades each time, and it is very easy to use. Become.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic perspective view of an essential part for explaining an embodiment of a control box according to the present invention, and FIG. 2 is a foot used by being connected to the control box shown in FIG. FIG. 1 is a schematic plan view for explaining an embodiment of a control. In FIG. 1, reference numeral 10 denotes a control box, and the control box 10 includes:
At least two micro-engine handpieces 11,
12 are detachably mounted, and these are appropriately selected and used.

As shown in FIG. 1, the control box 10 includes a main power switch 1, an instrument (motor) selection switch 3 (instrument (motor) 1
When 1 is selected, the pilot lamp 3 ₁₁ lights up,
When instrument (motor) 12 is selected, the pilot lamp 3 ₁₂ goes on), when the rotation direction select switch 4 (forward rotation, the pilot lamp 4 ₁ is lit,
When the reverse rotation, the pilot lamp 4 ₂ goes on), the pilot lamp 5 ₁ lit when the interlock is water injection and irrigation selection switch 5 (driving of the instrument (rotation of the motor), when the water injection only pilot lamp 5 ₂ lights, either the pilot when only the driving of the instrument (rotation of the motor) even without lighting, "anti = off" has become a), the rotation of the instrument (motor) 11 or 12 Volume knob 6 to adjust the number, water volume adjustment knob 7 to adjust the water volume at the time of water injection, pilot lamp indicating standby state (when blinking (on): all operations are impossible, when lit (off): all (Operation is possible) 8 and a buzzer 9.

FIG. 2 shows a foot controller 20 used by being connected to the control box 10 shown in FIG.
The foot controller 20 is a motor start / stop switch operating plate 2 that starts and stops the rotation of the motor of the instrument 11 or 12 when depressed.
1, an instrument selection switch operation plate 22 for selecting the instrument 11 or 12, a forward / reverse selection switch operation plate 23 for switching between forward and reverse rotation of the motor of the selected instrument, irrigation (rotation of the motor) And an irrigation selection switch actuating plate 24 for selecting between water and water injection, water injection only, and motor rotation only. Specifically, for example, the selection switch actuating plate 22
Standing on one side of the foot plate 21, one instrument is selected from a plurality of instruments,
The forward / reverse selection switch operation plate 23 is provided upright on the other side of the foot plate 21 to switch between forward and reverse rotation of the motor of the selected instrument. To select the irrigation of the selected instrument.

At least two instruments 11 and 12 are removably mounted on the control box 10. One of the instruments is selected and used at the time of use. The control box 10 is connected to the foot controller 20 shown in FIG. 2, and the foot controller 20 selects one of the instruments 11 and 12 and controls the instrument as described above.

The control box 10
Indicates an instrument selection switch 3 and a forward / reverse rotation for selecting forward / reverse rotation of the motor of the selected instrument.
It has a reverse selection switch 4 and an irrigation selection switch 5 for selecting the irrigation of the selected instrument. These are provided on the foot switch 20, respectively. Reverse rotation selection switch operation plate 23, and has the same operation as the irrigation selection switch operation plate 24,
Either of them can be used by manual operation or foot operation,
Forward / reverse selection and irrigation can be selected.

Further, the control box 10 comprises:
A power switch 1 is provided. When the power switch 1 is turned off, the next time the power switch 1 is turned on, the power switch 1 is always set to an initial state, and the instrument is a predetermined instrument, for example, an instrument 11. Is selected, and the rotation of the motor is selected to be forward rotation, and the irrigation is turned off. This makes it possible to prevent an incorrect instrument selection, wrong rotation direction, wrong water injection, etc. when the instrument is started. I'm trying to get rid of it.

Further, when the selection of the instrument is switched, for example, when the use of the instrument 11 is switched to the use of the instrument 12, the motor of the instrument 12 is selected to rotate in the forward direction. Is turned off, so as to eliminate an error in the rotation direction, an error in water injection, and the like when switching instruments.

Further, when the instrument selection switch 3 (or the switch operating plate 22) is pressed for a predetermined time or more, a standby state in which all operations are disabled is performed.
When the button is pressed for a predetermined time or more, all operations are enabled, and when the standby state is switched from the on state to the off state, the operation always returns to the initial state. As a result, the use of the instrument was interrupted, and the safety was ensured by preventing the instrument from being driven even if the foot plate was accidentally pressed while performing other work. Things.

Further, at the moment when the standby state is switched on / off, the buzzer 9 sounds for about one second to notify that the switching has been performed. , flashing pilot lamp 8, when all operations possible off is adapted to the pilot lamp 8 is lighted, further, the reverse rotation selection (pilot lamp 4 ₂
(When is lit), the buzzer 9 always sounds, regardless of whether the motor is running or not, thereby improving safety.
