Abstract
A biopsy system includes an endoscope which includes an insertion portion having a channel, and a bendable portion provided in a distal end portion of the insertion portion; a needle tube which includes a distal end region, and a proximal end region having a higher bending rigidity than that of the distal end region; a sheath which can be inserted into the channel and inserted through by the needle tube; an attachment adapter which is provided on a proximal end side of the sheath and is capable of being mounted at the endoscope; and a connection member which connects the distal end region and the proximal end region, wherein the connection member can move within only a range of the insertion portion more proximal than a proximal end of the bendable portion and more distal than a proximal end of a follow-bending region.
