Endoscope system
First Claim
1. An endoscope system comprising:
- an endoscope in which an endoscope insertion portion that is inserted into a body extends from an endoscope operation portion that an operator controls;
a working channel that opens to a distal end portion of the endoscope insertion portion and passes through the endoscope, with its proximal end portion opening to the endoscope operation portion;
a connection conduit that branches from a branch portion formed in the proximal end portion of the working channel;
a suction conduit for suctioning tissue, being connected to a suction unit through the inside of the endoscope;
a tissue recovery device that is inserted into the connection conduit and a distal end of the suction conduit and is capable of trapping tissue which is drawn into the working channel by a suction of the suction unit via the suction conduit; and
an attachment that removably attaches a portion of the working channel that includes the branch portion and the distal end portion of the suction conduit with respect to the endoscope operation portion as one piece, wherein the attachment has a bypass conduit that bypasses the tissue recovery device to allow communication between the connection conduit and the suction conduit, with the bypass conduit being blocked when the tissue recovery device is attached and opened when the tissue recovery device is removed.

Abstract
In the endoscope system 1, a tissue recovery device 3 that recovers tissue is directly mounted on an endoscope 2. The tissue recovery device 3 has a filter portion, and the filter portion is inserted so as to traverse the conduit of the suction conduit 20 that passes inside the endoscope operation portion 10. The suction conduit 20 opens to the distal end portion of the endoscope insertion portion 11, and the working channel 23 branches off from the branch portion 22 that is provided further on the distal end side than the insertion location of the tissue recovery device 3. With this endoscope system, it is possible to reduce operational burden of the operator with regard to the endoscope system that includes the tissue recovery device that recovers tissue.
