ENDOSCOPE HAVING A TREATMENT TOOL RAISING BASE

摘要

An endoscope includes a raising base rotatably installed in an insertion portion of the endoscope, a recess formed in the insertion portion, a flexible control wire which is movable along an axis thereof relative to said insertion portion, a link member provided in the recess and connecting one end of the control wire to the raising base, and a cover which is detachably attached to the insertion portion to close the recess. The link member includes a rotational shaft which is coaxial with a of rotational axis of the raising base, the rotational shaft provided in the recess to be irrotatable relative to the raising base and detachably connected to the raising base; and a connecting portion detachably and irrotatably connected to the rotational shaft in the recess, the one end of the control wire being connected to the connecting portion at a position offset from the rotational shaft.

主权项

1. An endoscope comprising:
a control portion; an insertion portion which extends from said control portion; a raising base which is installed in said insertion portion to be rotatable; a recess which is formed in said insertion portion at a different position from said raising base; a flexible control wire which is movable along an axis thereof relative to said insertion portion, one end of said control wire being positioned in said recess, wherein a part of said control wire that extends toward said control portion from said one end of said control wire is positioned inside said insertion portion; a link member which is provided in said recess and connects said one end of said control wire to said raising base; and a cover which is detachably attached to said insertion portion to close said recess, thereby covering said one end of said control wire and said link member, wherein said link member includes a rotational shaft which is coaxial with an axis of rotation of said raising base, said rotational shaft being provided in said recess to be irrotatable relative to said raising base and to be detachably connected to said raising base; and a connecting portion which is detachably and irrotatably connected to said rotational shaft in said recess, said one end of said control wire being connected to a portion of said connecting portion at a position that is offset from said rotational shaft.
