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.
Claims13
An endoscope system comprising:
- an endoscope in which an endoscope insertion portion that is inserted into a body extends from an endoscope control portion that an operator controls;
- a suction conduit that opens to a distal end portion of the endoscope insertion portion and passes through the endoscope, with its proximal end portion connected to a suction unit;
- a working channel that branches off and extends from a branch portion that is formed in the suction conduit and allows the insertion of a treatment tool toward the opening of the distal end portion of the suction conduit;
- and
- a tissue recovery device that is provided in the endoscope control portion further to the proximal end side than the branch portion of the suction conduit and capable of trapping tissue that is suctioned by the suction conduit.
