Abstract
With respect to an endoscope distal hood component of the present invention, a protrusion of a distal hood component fitted to the distal end of an endoscope is formed to be elastically deformable in order that when this protrusion is pressed against an observation target, the protrusion is deformed due to an external force at that time, and a part thereof is entered into the range of the observational field of view. Since a part of the protrusion is entered into the range of the observational field of view, the surgeon becomes aware that the protrusion is pressed against the observation target, and does not further press the protrusion against the observation target.
Claims19
An endoscope distal hood component comprising a protrusion provided at a distal end of the insertion portion of an endoscope to be inserted into a lumen,
- wherein the protrusion is protruding in the direction of the observational field of view of the endoscope,
- wherein the protrusion has the shape which is not included within the range of the observational field of view,
- wherein the protrusion is made from an elastically deformable soft component,
- wherein the protrusion is formed in order that when the protrusion is deformed by an external force from the direction of the distal end or the side, the deformed portion is entered into the range of the observational field of view, and
- wherein the protrusion which is deformable is continuously formed along a circumference thereof.
