Abstract
An endoscope (1) including a handle (2) arranged at a proximal end and an insertion tube (3) extending from said handle (2) towards a distal end, a bending section (7) arranged at the distal end and controllable by and operator via control input means (8) arranged at the handle (2); and at least one insertion tube part with at least one lumen, wherein the bending section (7) is displaceable in said lumen so as to be movable relative to the insertion tube (3) from a retracted position within said lumen to an extended position at least partially outside said lumen.
Claims20
An endoscope comprising:
- a handle including a steering control knob;
- an insertion shaft affixed to the handle;
- a bending section affixed to the insertion shaft at a fixed distance from the handle, the bending section being sized and shaped to bend along a bending plane;
- and
- an insertion tube extending from the handle, the insertion tube including a lumen and being sized and shaped to translate longitudinally relative to the handle from a locked position to a retracted position,
- a vision device located, at least in part, between an outer circumferential surface of the bending section and an inner circumferential surface of the insertion tube, the vision device supported by the insertion tube to translate therewith,
- wherein a portion of the bending section is positioned within the lumen in the locked position, and
- wherein the portion of the bending section is positioned outside the lumen in the retracted position.

An endoscope comprising:
- a handle including a steering control knob;
- an insertion shaft affixed to the handle;
- a bending section affixed to the insertion shaft at a fixed distance from the handle, the bending section being sized and shaped to bend along a bending plane;
- an insertion tube extending from the handle, the insertion tube including a lumen and being sized and shaped to translate longitudinally relative to the handle from a locked position to a retracted position, wherein a portion of the bending section is positioned within the lumen in the locked position, and wherein the portion of the bending section is positioned outside the lumen in the retracted position;
- releasable locking means operable to place the insertion tube in the locked position and to release the insertion tube from the locked position;
- and
- an auxiliary handle affixed to the insertion tube and sized and shaped to translate over a distal end of the handle to place the insertion tube in the locked position.

A method of using an endoscope, comprising:
- gripping an endoscope including:
- a handle including a steering control knob;
- an insertion shaft affixed to the handle;
- a bending section affixed to the insertion shaft at a fixed distance from the handle, the bending section being sized and shaped to bend along a bending plane;
- an insertion tube extending from the handle, the insertion tube including a lumen and being sized and shaped to translate longitudinally relative to the handle from a locked position to a retracted position;
- and
- a vision device located, at least in part, between an outer circumferential surface of the bending section and an inner circumferential surface of the insertion tube, the vision device supported by the insertion tube to translate therewith,
- wherein a portion of the bending section is positioned within the lumen in the locked position, and
- wherein the portion of the bending section is positioned outside the lumen in the retracted position;
- with the insertion tube in the locked position, inserting the insertion tube into a patient;
- causing a distal end of the insertion tube to contact tissue of the patient;
- releasing the insertion tube from the locked position;
- retracting the insertion tube;
- and
- after retracting the insertion tube, steering the bending section.

A videoscope comprising:
- a handle including a handle extension;
- an auxiliary handle sized and shaped to translate and rotate on the handle extension;
- an insertion tube affixed to the auxiliary handle and including a lumen, the insertion tube sized and shaped to translate longitudinally relative to the handle from a locked position to a retracted position;
- a vision device located, at least in part, between an outer circumferential surface of the bending section and an inner circumferential surface of the insertion tube, the vision device supported by the insertion tube to translate therewith;
- an insertion shaft having a proximal end affixed to the handle extension and a distal end, the insertion shaft positioned within the lumen;
- and
- a bending section affixed to the distal end of the insertion shaft at a fixed distance from the handle,
- wherein a portion of the bending section is positioned within the lumen in the locked position, and
- wherein the portion of the bending section is positioned outside the lumen in the retracted position.
