Abstract

There is provided herein a tip section for an endoscope assembly that includes a fluid distribution device for circulating fluid for cleaning a body cavity. In an embodiment, the tip section includes a groove aligned with side jet channels, where multiple holes drilled above the groove, through the periphery of a tip cover covering the tip section, provide an exit for the fluid circulated by the side jet channels in all directions around the tip cover. In another embodiment, the tip section includes a removable attachment that covers jet channel openings. Multiple holes drilled through the cover provide a multiple jet exit for the fluid circulated by the jet channels in multiple directions around the tip cover.

First claim

We claim:

1. An imaging module for a medical device, comprising:
a circuit board assembly comprising:
a first base board; and
a second base board spaced from the first base board;

a first optical assembly including a first image sensor and a first at least one lens, wherein the first at least one lens is positioned between the first base board and the second base board; and
a second optical assembly including a second image sensor and a second at least one lens, wherein the second at least one lens is positioned between the first base board and the second base board;
wherein the first image sensor is connected to the first base board and the second base board, and the second image sensor is connected to the first base board and the second base board.

2. The imaging module of claim 1 , wherein each of the first image sensor and the second image sensor is configured to be bent or folded.

3. The imaging module of claim 1 , wherein:
the first image sensor includes i) first connector pins at a first end of the first image sensor and (ii) second connector pins at a second end of the first image sensor;
the first end opposes the second end;
the first connector pins are coupled to the first base board; and
the second connector pins are coupled to the second base board.

4. The imaging module of claim 3 , wherein:
the first connector pins are coupled to a first surface of the first base board;
the second connector pins are coupled to a second surface of the second base board;
the first surface faces a first direction, and
the second surface faces a second direction that is opposite the first direction.

5. The imaging module of claim 1 , wherein:
the first base board includes a first indentation; and
the first indentation is configured to receive the first image sensor.

6. The imaging module of claim 5 , wherein:
the second base board includes a second indentation; and
the second indentation is configured to receive the first image sensor.

7. The imaging module of claim 1 , wherein:
the first image sensor includes a first U-shaped portion; and
the first U-shaped portion extends around three sides of the first base board.

8. The imaging module of claim 7 , wherein:
the first image sensor includes a second U-shaped portion; and
the second U-shaped portion extends around three sides of the second base board.

9. The imaging module of claim 1 , further comprising:
a first optical assembly frame coupled to the first base board and the second base board;
wherein the first optical assembly is positioned within the first optical assembly frame.

10. The imaging module of claim 9 , further comprising:
a first support frame coupled to the first base board and the second base board;
wherein the first optical assembly frame is configured to be received within the first support frame.

11. The imaging module of claim 10 , wherein the first support frame is configured to be a heatsink.

12. The imaging module of claim 10 , wherein the first support frame is positioned between the first base board and the second base board.

13. The imaging module of claim 10 , wherein the first image sensor extends around three sides of the first support frame.

14. The imaging module of claim 10 , further comprising at least one lens positioned within the first support frame.

15. The imaging module of claim 10 , further comprising an electrical cable extending between the first base board and the second base board.

16. The imaging module of claim 15 , further comprising at least one illuminator coupled to the electrical cable.

17. The imaging module of claim 16 , wherein the at least one illuminator is coupled to the first base board and the second base board.

18. The imaging module of claim 1 , further comprising a support frame extending between the first base board and the second base board.

19. The imaging module of claim 18 , wherein the support frame is positioned at a distal end of the first base board and a distal end of the second base board.

20. The imaging module of claim 19 , wherein at least one illuminator is coupled to the support frame.
