ABSTRACT:
A tissue cutting device includes an insertion section which is inserted inside a specimen and extends from a distal end to a proximal end, openings which are formed in a distal end side of the insertion section inserted into the specimen, tissue cutting members which pass through the openings, extend such as to protrude in a direction intersecting the axial line of the length direction from the distal end of the insertion section to the proximal end, and are drawn into the insertion section from the same openings after forming a loop which tissue can be inserted into, a control member which is connected to the tissue cutting members, and a controller for controlling the control member; tissue passed through the loops being cut by controlling the control member and drawing the tissue cutting members from the openings into the insertion section.
