<P>PROBLEM TO BE SOLVED: To provide a frontward-projecting treatment instrument for endoscopes retaining a distal treatment member in a maximally projecting state without any need of an assistant when performing a treatment, and retaining the distal treatment member in a maximally retracted state without any need of the assistant when inserting/removing it relative to a treatment instrument insertion channel of an endoscope. <P>SOLUTION: This frontward-projecting treatment instrument is provided with an energization means 7 for energizing the distal treatment member 3 in the direction of projecting frontward from the distal end of a flexible sheath 1, and an operation member locking means 16 freely locking and unlocking a sliding member 14 relative to an operation part body 11 in a state where the distal treatment member 3 is drawn to the distal side of the flexible sheath 1 against the energization of the energization means 7. <P>COPYRIGHT: (C)2009,JPO&INPIT |
