(Fixed substance removal method)
Next, a method for removing cement fixed to a dental instrument using the fixed matter removing apparatus 10 will be described.

  When the inlay is mounted after the tooth decay has been shaved, cement used as an adhesive is kneaded using a metal spatula-like dental medical instrument immediately before treatment. Since this cement has a fast setting property, a cured product of the cement is firmly fixed to the dental medical instrument. Examples of cement include resin cement and zinc phosphate cement.

  First, the drive shaft is rotated by turning on the switch of the control unit and operating the electric motor 15. At this time, the rotation of the drive shaft is decelerated by the gear box 16 and output as the rotation of the output shaft 17. And the part which protruded from the brush exposure opening part 28 rotates the wire brush 11 toward the back side from the front side. The rotation speed of the wire brush 11 is, for example, 200 to 1500 rpm.

  Then, as shown in FIG. 5, after the dental medical instrument to which the cement is attached is inserted between the fixed blade 32 and the wire brush 11, the lower surface of the dental medical instrument is rotated with the brush of the wire brush 11. Abutting the outer peripheral surface of the wire tip of the portion 14 exposed, and abutting the upper surface against the fixed blade 32 using the abutting portion of the lower surface to the wire brush 11 as a fulcrum, With the lower side being in contact with the wire brush 11 and the upper side being in contact with the fixed blade 32, they are pulled out to the front side. At this time, the cement fixed to the lower surface of the dental medical instrument is scraped off by the wire, and the cement fixed to the upper surface is scraped off by the fixed blade 32. Further, since the dust box 19 is provided, the scraped cement adheres to the wire brush 11 and is carried, and also falls from the fixed blade 32 and passes through the brush exposure opening 28 and is collected in the dust box 19. It will be. Further, since the top plate 20 is provided, the fixed matter collected from the dust box 19 is prevented from being scattered to the periphery, and the necessary minimum of the rotating brush portion 14 is exposed to the outside, so that work safety is achieved. Will be achieved.

  Thereafter, the same operation is repeated with the upper and lower surfaces reversed.

  According to the method for removing cement from dental instruments using the above-described fixed substance removing apparatus 10, the cement fixed on both surfaces of the dental instruments can be easily performed with the wire brush 11 and the fixed blade 32 by a simple operation. It can be removed by scraping.

  In the present embodiment, the removal of the cement fixed to the dental medical instrument is intended, but the present invention is not particularly limited to this, and it may be the removal of the fixed matter of other elongated plate-shaped instruments.

  INDUSTRIAL APPLICABILITY The present invention is useful for a fixed object removing device for a long and thin flat plate instrument such as a dental medical instrument and a fixed object removing method using the same.
