Abstract

A treatment instrument includes a first coil and a second coil that is different from said first coil. The first and second coils are connected to each other. An operation wire is inserted in the first and second coils, and a tip end of the wire is connected to a treatment device. Upon movement of the wire, the treatment device operates. A method of manufacturing such a treatment instrument includes inserting one end of the first coil and one end of the second coil in a connection pipe from opposite ends thereof, exposing both ends of the connection pipe and corresponding portions of the first and second coils. The portions exposed to the arc columns are melted and connected.
