<P>PROBLEM TO BE SOLVED: To improve an electric-powered surgical instrument system used for an electric-powered handpiece for more facilitating the application of individual surgical instruments with different electric power and control signal specifications, and the use of these instruments together with their attachments in a different combination. <P>SOLUTION: This invention is characterized in that an electric-powered handpiece is provided with a motor to drive attachments, a switch to issue control signals and a memory for storing data on the motor, that a control table adjusts the motor speed based on control signals, prevents the motor from operating beyond the maximum speed stored in the memory, and calculates the maximum allowable current consumed by the motor based on the data in the memory showing the maximum allowable motor current allowed for the motor speed as well as individual instrumental speeds, and that if a comparison between motor's current consumption and maximum allowable current has shown that the motor consumed current beyond the maximum allowable level specified, the momentum signal given to the motor is adjusted. <P>COPYRIGHT: (C)2007,JPO&INPIT |
