Abstract
An endoscope includes a handle including a handle housing, an irrigation inlet port adapted to receive irrigation fluid, and an irrigation channel; and an insertion cord extending distally from the handle. The insertion cord includes an insertion tube; a bending section extending from the insertion tube; a distal tip extending from the bending section and including a tip housing; a camera at least partially enclosed in the tip housing; interstitial space within the insertion tube in fluid communication with the irrigation channel; and at least one interstitial flow opening in fluid communication with the interstitial space and adapted to discharge the irrigation fluid.
Claims18
An endoscope comprising:
- a handle including a handle housing, a control lever, an irrigation inlet port adapted to receive irrigation fluid, and an irrigation channel;
- pull wires connected to the control lever;
- an insertion cord extending distally from the handle, the insertion cord including:
- an insertion tube;
- a bending section extending from the insertion tube, the bending section comprising hinged segments including a distal segment, the bending section being configured to bend responsive to the pull wires being tensioned;
- a distal tip extending from the bending section and including a tip housing;
- a camera at least partially enclosed in the tip housing;
- a bending section cover;
- interstitial space within the insertion tube in fluid communication with the irrigation channel;
- and
- at least one interstitial flow opening in fluid communication with the interstitial space and adapted to discharge the irrigation fluid,
- wherein the bending section cover overlaps, and is bonded to, the distal segment and/or the tip housing, at circumferentially spaced bonding sites with unbonded portions of the bending section cover disposed between the bonding sites, and
- wherein the at least one interstitial flow opening comprises a gap between an unbonded and unperforated portion of the bending section cover and the distal segment and/or the tip housing.
