Abstract
A bending sheath for a probe being inserted in a channel of a forceps of an endoscope inserted in a body cavity of a patient for observing the diseased part thereof is disclosed. The bending sheath comprises a hollow sheath, at least one extended portion extending in the sheath axis direction from the sheath tip portion, and a tip holding member for holding detachably the inserted tip portion of the probe inserted in the sheath.
Claims25
A bending sheath comprising:
- a hollow sheath comprising a sheath tip portion;
- at least one extended portion integrally formed with and extending in a sheath axis direction of the hollow sheath from the sheath tip portion;
- and
- a tip holding member having a first end which is attached to the at least one extended portion and a second end which is closed to form a shape of a cap;
- and
- the at least one extended portion comprises a bendable section which bends to cause an end portion of said extended portion to be at an angle relative to the sheath axis direction.
