PROBLEM TO BE SOLVED: To provide a method and a device (particularly, a trocar and a trocar adapter) by which electric operation energy can be electrostatically connected to a cordless electric operation apparatus. SOLUTION: This operation trocar is constituted so as to electrostatically connect electric operation energy to a particularly adapted cordless electric operation apparatus. The electric operation trocar contains a cannula 10, a capacitive electric operation adapter 14 and a locking connector 17 to connect the cannula to the capacitive electric operation adapter 14. The cannula 10 is a slender tube insertable into a cavity part, a duct or a blood vessel of the human body. The electric operation adapter 14 contains a housing 15 having a slender central aperture 19, a base part capacitor plate and a tip capacitor plate which are placed in the slender aperture 19 and extend in the shaft direction along the slender aperture 19, first and second conductors, first and second external conductors, an outside housing and an electric cord 18. |
