An apparatus for supplying power to an electrosurgical device comprising a power output means (20) for providing a surgical current (SOUT), a switch means (22) for supplying the power output means (20) with a power signal (Sp) to provide the surgical current (SOUT), a first signal generation means (26) for supplying the switch means (22) with a switch signal (SLF) to turn on and off the switch means (22) with given timing, a second signal generation means (32) for supplying the power output means (20) with a surgical signal (SHF) having a period corresponding to the surgical current (SOUT), a timer means (28) triggered by the switch signal (SLF) and producing a timer signal (ST) for a given time (Ti) after being triggered, and a gate means (30) for allowing the surgical current (sOUT) to be delivered from the power output means (20) only while the timer signal (ST) is being produced. The surgical current (sOUT) is supplied from the power output means (20) to the electrosurgical device in accordance with the logical AND of the switch signal (SLF), the timer signal (ST) and the surgical signal (SHF). |
