1. A medical treatment device, comprising:
(i) an electrode portion having a grasping function, a coagulating function, and a cutting function, wherein said electrode portion further comprises:
a first electrode; anda second electrode arranged opposed to said first electrode, (ii) an operation portion for executing drive of said grasping function, said coagulating function, and said cutting function of said first electrode and said second electrode; (iii) a shaft portion for connecting said electrode portion and said operation portion, wherein said shaft portion comprises:
on an outer side thereof, an outer cylindrical tube, andon an inner side thereof, wherein said inner side comprises:
a conductive rod for supplying a microwave to said electrode portion, wherein said conductive rod comprises a coaxial cable, andan electrode operation rod comprising a towing wire that uses a flexible tubular structure as a guide for transmitting the operation force from said operation portion to said electrode portion,wherein said shaft portion and said electrode portion are connected to each other with a bent holder that is provided continuously from said shaft portion, and includes said outer cylindrical tube, said conductive rod, and said electrode operation rod, and wherein said outer cylindrical tube, said conductive rod, and said electrode operation rod each has a curving angle substantially the same as a curving angle of said bent holder in the same direction;
(iv) a connector portion, which is provided at one end of said operation portion and is connectable to a microwave power source; and (v) a turning member located at a connection portion between said shaft portion and said operation portion, for rotating a shaft to rotate said bent holder,wherein said medical treatment device utilizing the microwave being configured to:
hold body tissue between said first electrode and said second electrode; coagulate the body tissue by supplying the microwave to said electrodes; and cut the body tissue through a mutual action of said first electrode and said second electrode. |
