Abstract

There is provided herein an endoscope assembly, the assembly comprising at least one front-pointing camera and at least one front illuminator associated therewith, at least one side-pointing camera and at least one of side illuminator associated therewith, a first front working channel configured for insertion of a medical tool and a second front working channel configured for insertion of a medical tool.

Claims

1. An endoscope assembly, the assembly comprising:

a substantially cylindrical fluid channeling component having a length and a height, the fluid channeling component having, along said height, a first fraction and a second fraction, wherein;

the first fraction extends along the length of the fluid channeling component, and comprises a housing that has encased therein a first working channel extending along the length of said fluid channeling component,

the second fraction is a void, and

a second working channel of the fluid channeling component is on an opposite side of the void relative to the first working channel;

an electrical assembly configured to fit within said second fraction, wherein the electrical assembly comprises;

one or more cameras,

an integrated circuit board having mounted thereon the one or more cameras, and

one or more illuminators; and

a tip cover section configured to receive said fluid channeling component and said electrical assembly, wherein the tip section comprises;

one or more working channel ports, each of the one or more working channel ports being configured to align with one of said first and second working channels of the fluid channeling component,

one or more camera ports, each of the one or more camera ports being configured to align with one of said one or more cameras, and

one or more illuminator ports, wherein each of the one or more illuminator ports comprises an optical window, and each of the one or more illuminator ports is configured to align with one of said one or more illuminators.

2. The assembly according to claim 1, further comprising one or more fluid injectors configured for cleaning at least one of said one or more cameras and said one or more illuminators.

3. The assembly according to claim 1, further comprising a pathway fluid injector for inflating and/or cleaning a body cavity into which the endoscope assembly is inserted.

4. The assembly according to claim 1, wherein each of said one or more illuminators comprises a light-emitting diode (LED).

5. The assembly according to claim 1, wherein each of said one or more illuminators is configured to emit at least one or a combination of:

white light, ultraviolet light, infrared light, or near-infrared light.

6. The assembly according to claim 1, wherein each of said one or more cameras comprises an image sensor.

7. The assembly according to claim 1, further comprising a plurality of fluid injectors configured to emit fluid outwardly from an external surface of the endoscope assembly, wherein the plurality of fluid injectors are connected to a same fluid supply channel in the fluid channeling component.

8. The assembly according to claim 1, wherein the one or more cameras includes a plurality of cameras with differing fields of view, and wherein said fields of view of at least two of said plurality of cameras are at least partially overlapping.

9. The assembly according to claim 1, wherein each of said one or more cameras comprises a lens assembly providing a field of view of 90 degrees or more.

10. The assembly according to claim 1, wherein each of said one or more cameras comprises a lens assembly providing a field of view of 120 degrees or more.

11. The assembly according to claim 1, wherein each of said one or more cameras comprises a lens assembly providing a focal length of approximately 3-100 millimeters.

12. The assembly according to claim 1, wherein said one or more cameras comprises a plurality of cameras mounted on said integrated circuit board, the plurality of cameras including a front-pointing camera, a first side-pointing camera, and a second side-pointing camera, and wherein said one or more illuminators comprises a front-pointing illuminator, a first side-pointing illuminator, and a second side-point illuminator.

13. The assembly according to claim 12, wherein said first and second side-pointing cameras are directed toward opposing sides of the endoscope assembly.

14. The assembly of claim 1, wherein the tip section further comprises a third fraction, and wherein said second working channel is encased in the third fraction, the second working channel extending along the length of said fluid channeling component.

15. An endoscope assembly, the assembly comprising:

a substantially cylindrical fluid channeling component having a length and a height, the fluid channeling component having, along said height, a first fraction, a second fraction, and a third fraction, wherein;

the first fraction extends along the length of the fluid channeling component, and comprises a housing that has encased therein a first working channel extending along the length of said fluid channeling component,

the second fraction is a void, and

the third fraction extends along the length of the fluid channeling component, and comprises a housing that has encased therein a second working channel extending along the length of said fluid channeling component; and

an electrical assembly configured to fit within said second fraction, said electrical assembly configured to house at least one image sensor and at least one light source.

16. The assembly according to claim 15, wherein the first fraction is a first segment of a cylinder, the third fraction is a second segment of the cylinder, and the void extends between planar surfaces of the first and third fractions.

17. An endoscope assembly, the assembly comprising:

a substantially cylindrical fluid channeling component having a length and a height, the fluid channeling component having a base, a first leg, and a second leg, wherein;

the base is positioned at a proximal end of the fluid channeling component, the base including a first working channel and a second working channel,

the first leg projects distally from the base and houses therein the first working channel, the first working channel extending along the length of the fluid channeling component through the base and the first leg, and

the second leg projects distally from the base, the second leg being positioned on an opposite side of the base as the first leg, the second leg housing therein the second working channel, the second working channel extending along the length of the fluid channeling component through the base and the second leg,

wherein the first and second legs are configured to receive therebetween an electrical assembly including at least one of an image sensor or a light source, and wherein the first and second legs include curved surfaces configured to engage an internal surface of a cover configured to house the fluid channeling component.

18. The assembly according to claim 17, further including the electrical assembly, wherein the electrical assembly includes at least one image sensor and at least one light source.

19. The assembly according to claim 18, wherein the fluid channeling component includes a void between the first and second legs, and wherein the electrical assembly is slidably received by the first and second legs to be seated in the void.
