Electric operation apparatus
First Claim
1. An electric operation apparatus, comprising:
- a high frequency electric current generating circuit that generates a high frequency electric current for feeding the high frequency electric current to electrodes;
a direct current power supply circuit that supplies variable direct current electric power to said high frequency electric current generating circuit to adjust the output of said high frequency electric current generating circuit;
a detecting circuit including at least a sensor for monitoring the therapeutic condition brought about by said high frequency electric current;
a therapeutic condition estimation circuit that estimates a therapeutic condition brought about by said high frequency electric current, said therapeutic condition estimation circuit selecting a target value corresponding to the estimated therapeutic condition among a plurality of target values predetermined in correspondence with the therapeutic conditions; and
a supplied power setting circuit that sets the electric power supplied by said direct current power supply circuit, said supplied power setting circuit rendering said direct current power supply circuit a predetermined supply condition in order to reduce the supply power of said direct current power supply circuit if the detected value of said detection circuit reaches a target value selected by the therapeutic condition estimation circuit.

16. An output control method for an electric operation apparatus comprising a high frequency electric current generating circuit that generates a high frequency electric current for feeding the high frequency electric current to electrodes, a direct current power supply circuit that supplies variable direct current electric power to said high frequency electric current generating circuit to adjust the output of said high frequency electric current generating circuit, and a detecting circuit that monitors a therapeutic condition brought about by said high frequency electric current, the method comprising:
-
monitoring the therapeutic condition brought about by said high frequency electric current;
estimating a therapeutic condition using a thickness of a subject'"'"'s tissue between at least two electrodes that transmit the high frequency current to the tissue;
setting a target value based on an estimation result obtained at said estimating step; and
rendering said direct current power supply circuit a predetermined supply condition in order to reduce a supply power of said direct current power supply circuit if a detected result of said detecting circuit reaches a target value set at said setting step.
