Abstract
An endoscope hood of the present invention is provided with a cylindrical main hood body attached to an endoscope. The main hood body includes a fixing portion located substantially in a center. The fixing portion allows the inner circumferential surface of the main hood body to be forcibly fixed to the outer circumference of the distal end portion of the endoscope. The main hood body also includes a projection projected from the distal end portion of the main hood body and a non-fastened portion located at the rear end of the main hood body. The non-fastened portion is fitted with the outer circumference of the distal end portion of the endoscope without being fastened.
Claims16
An endoscope hood comprising:
- a projection extending from a distal end portion of an insertion section of an endoscope, to separate an optical member for observation from an object to be imaged when the endoscope hood is fixed to the distal end portion of the insertion section of the endoscope;
- a fixing portion located proximally of the projection, an inner surface of the fixing portion configured to be pressed against a circumferential surface of the insertion section to fix the endoscope hood to the insertion section of the endoscope;
- and
- a non-fastened portion located proximally of the fixing portion, the non-fastened portion including a portion which is not fixed to the circumferential surface of the insertion section of the endoscope when the fixing portion is pressed against the outer circumference of the insertion section of the endoscope.
An endoscope hood, comprising:
- a projection extending from the a distal end portion of an insertion section of an endoscope to separate an optical member for observation from an object to be imaged when the endoscope hood is fixed to the distal end portion of the insertion section of the endoscope;
- an integral section formed integrally with the projection at a distal end side of the projection and located at an outer circumferential surface of the insertion section when the endoscope hood is attached to the insertion section of the endoscope, the integral section having a fixing portion configured to be pressed against the outer circumferential surface of the insertion section to attach the endoscope hood to the endoscope, and having a removing portion to permit the endoscope hood to be removed from the endoscope.
