<P>PROBLEM TO BE SOLVED: To provide a high-frequency treatment instrument which is free from an entanglement of cord even when the operation part is rotated for rotating the tip. <P>SOLUTION: This instrument comprises a flexible tube inserted in a body cavity, an operation wire which is freely inserted back and forth in the flexible tube, a treatment part mounted at the tip of the operation wire for treating an affected part by applying high-frequency current, a high-frequency current applying part which is directly attached to the operation wire and applies the high-frequency current, and an operation part which is added to the base end part of the flexible tube for operating the treatment part via the operation wire, and the operation part has an operation wire insertion hole for inserting the operation wire and a slit part which is penetrated to the orthogonal direction to the axial line of the operation part while it is mounted over the predetermined area to the axial line direction and the operation wire is freely moved back and forth inside, and it has a rotary operation part which rotates around the axial line independently from the high-frequency current applying part while it rotates together with the treatment part via the operation wire and a first operation auxiliary part which is supported to freely slide to the axial line direction of the rotary operation part and aids the operation of the treatment part. <P>COPYRIGHT: (C)2010,JPO&INPIT |
