Step S516, it is judged whether there is a start signal input, if yes, go to step S518, if not, go to step S520.

Step S518, output the ultrasonic electrical signal.

Step S520, judging whether a trigger command for replacing the tool head is received, if yes, go to step S522, if not, go back to step S516 to execute the loop.

Step S522, write the currently used usage time and usage times to the electronic tag, update the usage time and usage times, and then return to step S502 to execute the loop.

Step S523, determine whether there is a stop signal input, if yes, go to step S524, if not, go back to step S523 to execute the loop.

Step S524, stop outputting the ultrasonic electric signal, stop timing, send the timing duration to the electronic tag, and then go to step S525.

In step S525, the electronic label updates the usage time, and then returns to step S502 to execute the loop.

To sum up, the ultrasonic surgical system and the cutter head management and control method provided by the present invention reduce the safety risk caused by the user's over-life use of the cutter, and improve the safety of the operation.
