Abstract
A disposable endoscope with a tip part including a vision sensor, an exterior housing having a front wall and a circumferential wall, an interior spacing of the exterior housing accommodating the vision sensor, and a camera window positioned at least partly in front of the vision sensor, the housing further comprising a nozzle provided at the distal end of the tip part and configured to flush an exterior surface of the window, wherein the front wall and the nozzle are integrally formed in one piece from one polymer material.
Claims19
An endoscope comprising:
- a tip part, the tip part including:
- a housing having a proximal end, a front end opposite the proximal end, a circumferential wall extending from the front end to the proximal end, a front wall, and a nozzle, the circumferential wall and the front wall defining an interior spacing of the housing;
- a vision sensor positioned in the housing;
- and
- a camera window positioned at the front end of the housing;
- wherein the housing further comprises, extending proximally from a proximal surface of the front wall, a gas channel and a liquid channel, the gas channel sized and shaped to receive a distal end of a gas tube and the liquid channel sized and shaped to receive a distal end of a liquid tube,
- wherein the nozzle comprises a nozzle roof positioned distally of the gas channel and the liquid channel, the nozzle roof defining a nozzle outlet,
- wherein the gas channel, the liquid channel, the nozzle outlet and the camera window are aligned such that a plane parallel to a longitudinal dimension of the distal tip traverses the gas channel, the liquid channel, the nozzle outlet and the camera window, and
- wherein the nozzle roof is sized and shaped to cause a gas and a liquid discharged through the distal ends of the gas tube and the liquid tube to impinge on, and be redirected by, the nozzle roof through the nozzle outlet toward the camera window.
An endoscope comprising:
- a tip part including:
- a front wall;
- a nozzle integrally formed in one piece with the front wall;
- a vision sensor;
- and
- a camera window sealingly bonded to the front wall and positioned distally of the vision sensor;
- a gas channel and a liquid channel, the gas channel and the liquid channel extending proximally from the front wall, the gas channel sized and shaped to receive a distal end of a gas tube and the liquid channel sized and shaped to receive a distal end of a liquid tube,
- wherein the nozzle comprises a nozzle roof positioned distally of the gas channel and the liquid channel, the nozzle roof defining a nozzle outlet,
- wherein the gas channel, the liquid channel, the nozzle outlet and the camera window are aligned such that a plane parallel to a longitudinal dimension of the distal tip traverses the gas channel, the liquid channel, the nozzle outlet and the camera window, and
- wherein the nozzle roof is sized and shaped to cause a gas and a liquid discharged through the distal ends of the gas tube and the liquid tube to impinge on, and be redirected by, the nozzle roof through the nozzle outlet toward the camera window.
A method to manufacture an endoscope comprising a tip part, the method comprising:
- integrally molding in one piece a front wall, a circumferential wall, and a nozzle, the front wall and the circumferential wall forming a housing defining an internal space;
- positioning a vision sensor in the internal space;
- positioning a camera window at the front end of the housing;
- wherein the front wall includes, extending proximally from a proximal surface of the front wall, a gas channel and a liquid channel, the gas channel sized and shaped to receive a distal end of a gas tube and the liquid channel sized and shaped to receive a distal end of a liquid tube,
- wherein the nozzle comprises a nozzle roof positioned distally of the gas channel and the liquid channel, the nozzle roof defining a nozzle outlet,
- wherein the gas channel, the liquid channel, the nozzle outlet and the camera window are aligned such that a plane parallel to a longitudinal dimension of the distal tip traverses the gas channel, the liquid channel, the nozzle outlet and the camera window, and
- wherein the nozzle roof is sized and shaped to cause a gas and a liquid discharged through the distal ends of the gas tube and the liquid tube to impinge on, and be redirected by, the nozzle roof through the nozzle outlet toward the camera window.
