Disclosed are an electric coagulation power handle, and electric coagulation planing tools and a planing assembly. The handle comprises a handle housing (1) and a power assembly. The handle housing (1) has an interface used to connect and drive the tools (2). The handle also comprises electric coagulation handle circuitry, and the electric coagulation handle circuitry comprises an output electrode arranged inside the interface. After the tools (2) are mounted on a port, the output electrode is electrically connected to the electric coagulation tool circuitry of the tools (2). After the tools (2) are inserted, power can be directly supplied to the electric coagulation tool circuitry inside the tools (2) through arranging the output electrode on the interface of the handle, so as to make the electric coagulation work normally. At the same time, the arrangement of the electric coagulation handle circuitry does not affect the normal installation of the tools, and hence the electric coagulation planing handle is enabled to possess the functions of electric coagulation and planing at the same time. The electric coagulation planing handle can promptly stop bleeding, prevent waiting times during the operation, while avoiding a cable from being externally connected to the tool, and guarantee that the vision of the surgeon is not affected during the operation. The operation will not be inconvenienced due to the peripheral connecting base or cable connection of the electric coagulation circuitry, thereby reducing interference with the operation and decreasing the difficulty of the operation.La présente invention concerne un manche de coagulation électrique, et des outils dabrasion et un ensemble dabrasion par coagulation électrique. Ledit manche comprend un logement (1) de manche et un ensemble dalimentation. Ledit logement (1) de manche comprend une interface utilisée pour être reliée aux outils (2) et les commander. Ledit manche comprend également un circuit de manche de coa
