摘要： PROBLEM TO BE SOLVED: To provide an electrosurgery apparatus of high energy efficiency capable of preventing the vicinity of an energizing part from becoming in an excess pressure state. SOLUTION: This electrosurgery apparatus is a monopolar type electrosurgery apparatus 1 which is provided with a liquid injection means for injecting a physiological saline solution, and applies a high-frequency current (high-frequency power) to biotissues and performs the electrosurgery of the biotissues. The apparatus 1 is provided with an apparatus body 2, a handpiece 3 and a counter electrode plate 4 connected to the apparatus body 2. Into the handpiece 3, the pressure sensitive part 721 of a peripheral pressure sensor and a temperature sensor 71 are installed. The apparatus body 2 is provided with a central operating unit 61, a pump 62, a power source for high-frequency output, a high-frequency output device, an isolation transformer, a high-frequency output monitoring device, an injection pressure sensor 67, the circuit part 722 of the peripheral pressure sensor, a display part and an operation part, or the like. The central operation unit 61 controls the high-frequency current to be applied to the biotissues on the basis of the detection result of the peripheral pressure sensor. COPYRIGHT: (C)2004,JPO
