The chip is configured in a shape that meets each purpose, such as scaling and smoothing of the root surface after scaling (root planing). The straight type, contra type and scaling handpieces 12 to 14 correspond to the dental instrument of the present invention.

For example, the instrument hose drawing amount adjusting device of the present invention is mounted inside the work table 7.
As shown in FIG. 3, the work table 7 has a control unit 60, an operation unit 10, an individual return switch 30, an electromagnetic valve 40, and a brake device 50, which are connected via a bus.
The control unit 60 includes a CPU, a memory, and the like, and can control the operation of the work table 7 by loading various programs and data stored in, for example, a ROM of the memory into the RAM and executing the various programs. .

  The individual return switch 30 includes, for example, a straight switch 31, contra switches 32 and 33, and a scaling switch 34, and is provided on the front plate 8 a of the holder 8. In addition, in this embodiment, although each switch 31-34 demonstrates in the example provided in the front board 8a, you may install in the touch panel of the operation part 10, for example. It is also possible to provide a switch for a syringe.

  As shown in FIG. 4, the front plate 8a of the holder 8 is formed with, for example, five holes aligned in the horizontal direction, and sequentially from the left side of the figure, the syringe hole 8b, the straight hole 8c, and the contra hole 8d. 8e and a scaling hole 8f are provided through the front plate 8a. The straight switch 31 is near the straight hole 8c, the contra switch 32 is near the contra hole 8d, the contra switch 33 is near the contra hole 8e, and the scaling switch 34 is near the scaling hole 8f. Are provided respectively.

  Each of the switches 31 to 34 is formed, for example, in a convex shape in cross section, the central portion of the convex shape protrudes outward from the front plate 8a, and the convex back surface portion is biased by, for example, a spring (not shown). Yes. Thereby, each switch 31-34 moves toward the inner side of the holder 8 against the urging force of the spring while pressing the convex central portion with, for example, a finger, and when the finger is released, It moves to the near side of the holder 8 by the urging force.

  The electromagnetic valve 40 and the brake device 50 are accommodated in the hose accommodating part 9, for example. As shown in FIG. 3, the electromagnetic valve 40 includes, for example, a spool type straight valve 41, contra valves 42 and 43, and a scaling valve 44. The brake device 50 includes a straight brake 51, contra brakes 52 and 53, and a scaling brake 54, all having the same structure.

  As an example, the straight-type handpiece 12 will be described. The hose connected to the handpiece 12 is wound around a pulley (not shown) and stored in the hose storage portion 9. The pulley is urged to the back side of the hose storage 9 by, for example, a spring (not shown). The straight brake 51 can brake the position of the pulley, and the straight valve 41 is configured to be able to supply air to the straight brake 51.

For this reason, for example, when the straight valve 41 is open, air is supplied to a predetermined flow path, the straight brake 51 is operated, and the position of the pulley is locked and connected to the handpiece 12. The length of the hose is maintained.
On the other hand, for example, when the valve 41 is closed, air is supplied to the other flow paths, and air is not supplied to the predetermined flow paths. As a result, the brake 51 is deactivated, the position of the pulley is unlocked, and the hose connected to the handpiece 12 is returned into the work table 7.

The control unit 60 has a pull back adjustment unit 61. The pullback adjustment unit 61 outputs a drive signal to each of the valves 41 to 44 based on the signals of the switches 31 to 34, respectively.
Further, the signal of the batch return switch 22 of the foot controller 20 is configured to be input to the work table 7, and the pullback adjustment unit 61 sends a drive signal to each valve 41 to 44 based on the signal of the batch return switch 22. Output at the same time. In the present embodiment, the example in which the batch return switch 22 is provided in the foot controller 20 has been described. However, the batch return switch 22 may be installed on the touch panel of the operation unit 10, for example.

  Then, the pull back adjustment unit 61 pulls back only one dental instrument to the work table 7 depending on whether it is a signal of each switch 31 to 34 or a signal of the batch return switch 22 and a plurality of operations. It is possible to set the operation of pulling back (for example, four) dental instruments to the work table 7 at the same time.

  For example, when the surgeon wants to use the straight type handpiece 12, the operator holds the handpiece 12 and pulls it out of the work table 7. Thereafter, it is assumed that the surgeon intends to use the handpiece 14 for scaling, and the assistant replaces the bar 13a of the straight-type handpiece 12 while using the handpiece 14 for scaling. .

  When the assistant has finished replacing the bar 13a of the handpiece 12, the straight-type handpiece 12 needs to be returned to the work table 7. However, since the scaling handpiece 14 is in use, only the straight-type handpiece 12 is returned to the work table 7. Therefore, for example, when the helper presses the straight switch 31, while the switch 31 is being pressed, the signal from the switch 31 is detected by the pull back adjustment unit 61, and the pull back adjustment unit 61 closes the straight valve 41. To do.

When the straight valve 41 is closed, air is not supplied to the predetermined flow path but air is supplied to the other flow paths. Only the connected hose is pulled back into the work table 7.
On the other hand, for example, when it is desired to clean the inside of the work table 7, the straight type hand piece 12, the contra type hand piece 13, and the scaling hand piece 14 are pulled out from the work table 7. Then, the case where the water in the work table 7 was drained through each handpiece 12-14 is assumed.

  After the work table 7 is dried, it is necessary to quickly return the handpieces 12 to 14 to the work table 7. Therefore, when the collective return switch 22 of the foot controller 20 is pressed, a signal from the switch 22 is detected by the return adjustment unit 61, and the return adjustment unit 61 detects the straight valve 41, the contra valves 42 and 43, and the scaling valve 44. Is closed.

When the straight valve 41, the contra valves 42 and 43, and the scaling valve 44 are closed, the straight brake 51, the contra brakes 52 and 53, and the scaling brake 54 all stop operating, and each handpiece Each hose connected to 12-14 is pulled back into the work table 7 at the same time.
Although the example in which the bar 13a of the straight-type handpiece 12 is replaced while the scaling handpiece 14 is in use has been described, if it is in an inactive state, in addition to the straight-type handpiece 12, a contra The bar 13a of the mold handpiece 13 can also be replaced at the same time.

  As described above, since the returning operation of the pull-back adjusting unit 61 can be set, it is possible to return only the straight valve 41 to the work table 7 such as after the replacement of the bar 13a. Such straight, contra, and scaling handpieces 12 to 14 can be returned to the work table 7 at the same time. Therefore, it is possible to provide an instrument hose pull-out amount adjusting device that can handle many aspects.

If the straight, contra, and scaling switches 31 to 34 are installed on the front plate 8 a of the holder 8, the handpieces 12 to 14 to be returned to the work table 7 can be easily selected. Furthermore, the straight switch 31 is provided in the vicinity of the straight-type handpiece 12, and the handpieces 12 to 14 to be returned to the work table 7 can be reliably selected.
Furthermore, if the batch return switch 22 is provided in the foot controller 20, each of the straight type, contra type and scaling handpieces 12 to 14 can be quickly returned to the work table 7.

In the above embodiment, an example of a spool type electromagnetic valve has been described. However, the present invention is not necessarily limited to this example. For example, a poppet type electromagnetic valve that closes a predetermined flow path when de-energized and opens this flow path when energized may be used.
Further, the example in which the hose can be returned to the work table while the switch is pressed has been described. However, the hose can be returned to the work table when the switch is pressed once, and the length of the hose can be maintained when the switch is pressed once again. Also, the brake device is not limited to the air drive type, and a known configuration can be adopted.
