摘要:
An elastically deformable elastic deformation portion (204) is disposed at a distal end portion of a cylindrical hood main body (202) attached on an outer peripheral surface of a distal end portion (15) of an endoscope (2), and the elastic deformation portion (204) is configured such that a distal end portion of the elastic deformation portion (204) abuts on an analyte to position an observation position of a second imaging unit (30) at a magnification observation time utilizing the second imaging unit (30) while the elastic deformation portion (204) is elastically deformable up to a position where a first imaging unit (28) abuts on an analyte at a contact observation time utilizing the first imaging unit (28). Thereby, a distal end hood for an endoscope where observation of a surface of a body tissue utilizing an ordinary observation optical system can be performed stably even by an endoscope provided with the observation optical system of an object contact type where observation is performed in a contact state with a body tissue, and object contact observation where observation is performed in a contact state of the observation optical system of an object contact type with a body tissue can be performed stably, and an endoscope with a hood are provided.
