Abstract
An endoscope having a proximal end, a distal end, a handle, and an insertion tube that terminates in a tip section. The tip section includes a bending section and an articulated tip part, and the bending section includes articulated segments, each articulated segment including a guide passage for a control member. The proximal end of the elongated control member is attached to an operating member arranged at the handle and the distal end of the elongated control member is attached to the most distal articulated segment of the bending section. An intermediate section of the elongated control member passes through said guide passages. The intermediate section has a reduced overall cross-sectional area as compared to the majority of said elongated control member.
Claims15
An endoscope having a proximal end and a distal end, said endoscope comprising:
- a handle at the proximal end;
- an operating member arranged at the handle;
- an insertion tube extending from the handle towards the distal end of the endoscope, said insertion tube terminating in a tip section at the distal end of the endoscope, the tip section comprising a bending section and an articulated tip part, the bending section comprising articulated segments and a most distal articulated segment extending distally from the articulated segments, each of said articulated segments comprising a guide passage;
- and
- an elongated control member having a proximal end, a distal end, and an intermediate section between the proximal end and the distal end, the proximal end of the elongated control member being attached to the operating member arranged at the handle,
- wherein the distal end of the elongated control member is attached to the most distal articulated segment of the bending section,
- wherein the intermediate section of the elongated control member passes through said guide passages and has a reduced cross-sectional area which is smaller than a cross-sectional area of a section of the elongated control member proximal of the intermediate section, and
- wherein the elongated control member comprises a tube with a collapsed part, wherein the collapsed part comprises the reduced cross-sectional area.
An endoscope having a proximal end and a distal end, said endoscope comprising:
- a handle at the proximal end;
- an operating member arranged at the handle;
- an insertion tube extending from the handle towards the distal end of the endoscope, said insertion tube terminating in a tip section at the distal end of the endoscope, the tip section comprising a bending section and an articulated tip part, the bending section comprising articulated segments and a most distal articulated segment extending distally from the articulated segments, each of said articulated segments comprising a guide passage;
- and
- an elongated control member having a proximal end, a distal end, and an intermediate section between the proximal end and the distal end, the proximal end of the elongated control member being attached to the operating member arranged at the handle,
- wherein the distal end of the elongated control member is attached to the most distal articulated segment of the bending section,
- wherein the intermediate section of the elongated control member passes through said guide passages and has a reduced cross-sectional area which is smaller than a cross-sectional area of a section of the elongated control member proximal of the intermediate section, and
- wherein the elongated control member has a cross-section with a circular periphery having a diameter, from the proximal end to the intermediate section, and along the intermediate section has a cross-section with a height equal to the diameter and a width smaller than the diameter.
An endoscope having a proximal end and a distal end, said endoscope comprising:
- a handle at the proximal end;
- an operating member arranged at the handle;
- an insertion tube extending from the handle towards the distal end of the endoscope, said insertion tube comprising a bending section having articulated segments and a most distal articulated segment extending distally from the articulated segments, each of said articulated segments comprising a guide passage having a cross-section with a height and a width, wherein the height is larger than the width;
- and
- an elongated control member having a proximal end, a distal end, and an intermediate section between the proximal end and the distal end, the intermediate section having a cross-section corresponding to the cross-section of the guide passages, and the elongated control member having a cross-section along the proximal end with a height and a width, wherein the height is equal to the width.
