<P>PROBLEM TO BE SOLVED: To make a taken-up piece automatically operate when a surgeon takes up one optional hand piece from among a plurality of the micro-motor hand pieces which are connected to an operation box. <P>SOLUTION: This micro-motor hand piece unit for oral cavity surgery is composed of the plurality of micro-motor hand pieces 1(1<SB POS="POST">1</SB>, 1<SB POS="POST">2</SB>), and the operation box 10 to which the plurality of hand pieces are attached. An optional desired one hand piece is selected by the surgeon, and oral cavity surgery treatment is performed by using the selected hand piece. The unit also comprises an IC chip 20 carried by the surgeon, and sensors 5(5<SB POS="POST">1</SB>, 5<SB POS="POST">2</SB>) which are embedded in the hand pieces 1<SB POS="POST">1</SB>, 1<SB POS="POST">2</SB>, respectively, and detect the IC chip when the IC chip 20 approximates. When the surgeon carries the IC ship 20 and takes it in his/her hand, the sensor 5 detects the IC ship 20, and changeover switches 11<SB POS="POST">1</SB>, 11<SB POS="POST">2</SB>in the operation box 10 are automatically switched so that the hand piece is brought into an operable state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
