ABSTRACT:
A blood coagulating apparatus for stopping bleeding by heating the bleeding portion of the living body while producing an electric discharge on the bleeding portion. A patient plate which is capable of maintaining the state of being electrically connected to the living body is placed on the living body. An active electrode including an electrolyte ejector is brought to the vicinity of the bleeding portion. The electrolyte ejector includes an ejector for supplying an electrolyte to an air passage for passing air therethrough at a high speed so as to mix the electrolyte with air and ejecting the atomized electrolyte to the bleeding portion. The electric discharge produced in the vicinity of the bleeding portion by applying a high-frequency voltage between the active electrode and the patient plate is made stable and effective by ejecting the atomized electrolyte toward the bleeding portion. Thus, a uniform coagulation spot is formed and stable hemostatis is enabled.
