ELECTRON COAGULATIVE SCALPEL Russian patent published in 2007 - IPC A61B17/3211 A61B18/12 

FIELD: medical equipment.

SUBSTANCE: electron scalpel has manipulator, electrode for closing electric circuit, which circuit is connected with tissues to be coagulated, electric power circuit voltage rectifying circuit, which circuit applies rectified and direct voltage into radio-frequency circuit, which circuit is made for provision of main carrying frequency current signal at output, which frequency is defined by oscillator. Current signal is applied as signal, feeding manipulator, by means of radio-frequency transformer. Resulting signal, achieved as a result of combination of carrier frequency rectangular signal and modulating signal, is applied to manipulator. Resulting signal circulates in resonant circuit with wide band-pass at frequency of carrier frequency signal. Resulting signal have the same frequency as energy transmitted to blood to be coagulated. Energy has to be sufficient for increasing blood temperature subject to treatment. Fibrinogen denaturation, containing in tissue, can be performed to fibrin easier.

EFFECT: lower traumatism of surgical operation.
