Abstract: Provided is an endoscope sheath including: a sheath body having an elongated rotating section and a stationary section, which are coupled to each other in a relatively rotatable manner about a longitudinal axis; a first passage along the axis; a second passage parallel to the first passage; an outlet through which a proximal end of an injection needle inserted in the second passage is pulled outside, the outlet being capable of changing a pullout position of the proximal end of the needle relative to the stationary section in the circumferential direction; and holders provided in the stationary section and separated by intervals in the circumferential direction, each holder securing an injector having the needle to the stationary section at a position where the needle protrudes from the distal end of the body and releasing the injector at a position where the needle is accommodated inside the body.
