<p>PROBLEM TO BE SOLVED: To provide an endoscope system which can reliably prevent scattering of bodily fluid or the like adhered to a treatment instrument when taking out the treatment instrument from a hand operation part.SOLUTION: A male screw part 50 is formed in a flexible cord part 41 of a treatment instrument 11. In a forceps plug 36 of a hand operation part 12 of an endoscope, a female screw part 55 screwed in the male screw part 50 is formed. In using the treatment instrument 11, the male screw part 50 is rotated and inserted. In pulling the treatment instrument 11 out after the treatment is over, the male screw part 50 is engaged with the female screw part 55 of the forceps plug 36, and pull-out operation of the treatment instrument 11 is temporarily stopped. After this, the treatment instrument 11 is rotated to screw the male screw part 50 and the female screw part 55, and the treatment instrument 11 can be slowly pulled out of the forceps plug 36. The treatment instrument 11 is not pulled out with momentum when the treatment instrument 11 is pulled out, and bodily fluid or the like adhered to the treatment instrument 11 stops scattering.</p> |
