The invention discloses an apparatus and a method for welding biological tissue by a high-frequency current. The apparatus comprises a high-frequency signal generator system, a power amplifying system, a control system and a photoelectric detection system, wherein the high-frequency signal generator system is used for generating a modulating high-frequency signal; the power amplifying system is used for amplifying the high-frequency signal and the direct current obtained by rectifying and filtering through a field effect transistor to generate a current which is needed by welding; the controlsystem is used for adjusting the welding power in real time to adapt the impedance of the to-be-welded tissue, and applying the welding current in a welding circulation process according to a set power curve; and the photoelectric detection system is used for collecting an optical signal in a biological tissue welding region in the collecting and welding process and converting the optical signal into a temperature signal
