1. An endoscope comprising:
- an endoscope insertion section used to be inserted into a human body; and
an endoscope-maneuvering section maneuvered by a surgeon in the exterior of the human body, a channel that allows insertion of an endoscope instrument therethrough being formed from a distal end section of the endoscope insertion section to the endoscope-maneuvering section, whereina tissue-suctioning pipeline is connected to the vicinity of an opening of the distal end of the channel, the tissue-suctioning pipeline being capable of connecting to a suction source that suctions a living tissue captured by the endoscope instrument.

Abstract
An endoscope system 1 according to the present invention is configured to include an endoscope 2 and an instrument 3. A first pipeline system 20 and a second pipeline system 30 are formed in the endoscope 2. A tissue grasped by the instrument 3 is retracted into a forceps channel 15, autopsy cups 79 are opened, and water-supply and suctioning are conducted to the grasped tissue by using the first pipeline system 20 and the second pipeline system 30, and then, the grasped tissue is collected from a tissue-suctioning pipeline 46 to a tissue-grasping device 17.
