Abstract

The present specification describes a jet distributor provided to supply fluids to each of a plurality of jet openings in a multi-jet endoscope tip. In an embodiment, the jet distributor is supplied with a fluid from a jet pump. The jet distributor includes at least two fluid channels to provide the fluid supplied via the jet pump to the front-jet, right-side-jets and left-side-jets in the endoscope tip. The jet-distributor includes a motor which rotates a rotating plug. The rotating plug includes an internal fluid pathway which becomes intermittently aligned with each of a plurality of fluid output channels in the jet distributor as the plug rotates, thereby providing fluid in a successive manner to the jets in the endoscope tip.

Claims

1. A method for distributing fluid from a source external to an endoscope into a plurality of fluid channels positioned within the endoscope, comprising:

operating a pump coupled to a fluid input channel of a fluid distributor device;

flowing fluid through an internal fluid pathway that is in fluid communication with the fluid input channel, wherein the fluid flows towards a plurality of output channels that are in fluid communication with the plurality of fluid channels positioned within an endoscope connector of the endoscope;

activating a motor connected to a distributor rotating plug via a motor shaft, wherein the activating rotates the rotating plug connected to the fluid distributor device;

intermittently aligning the internal fluid pathway with each of the plurality of output channels, allowing fluid to move from the fluid input channel, through the internal fluid pathway, successively into each of the plurality of fluid output channels, and successively into each of the plurality of fluid channels.

2. The method of claim 1, further comprising rotatably moving, within the fluid distributor device, a distributing element attached to the distributor rotating plug, wherein the distributing element comprises the internal fluid pathway.

3. The method of claim 1, further comprising positioning the fluid distributor device, the motor, and the motor shaft within the housing.

4. The method of claim 3, comprising using a locking element to fixedly position the fluid distributor device within the housing.

5. The method of claim 1, wherein the flowing of the fluid comprises flowing the fluid through at least three fluid output channels, and wherein each of the at least three fluid output channels is separately and individually connected to at least three fluid channels positioned within the endoscope connector.

6. The method of claim 1, wherein the activating further comprises rotating the distributor rotating plug at a rate ranging between 30 revolutions per minute (rpm) and 100 rpm.

7. The method of claim 1, wherein, when in each intermittent alignment, said internal fluid pathway is in fluid communication with one of said plurality of fluid output channels and is not in fluid communication with any remaining ones of said plurality of fluid output channels.

8. The method of claim 1, wherein said endoscope connector is positioned within a main control unit, and wherein the main control unit is external to said endoscope.

9. The method of claim 1, wherein said endoscope connector comprises a plurality of connectors for connecting said plurality of fluid channels with said plurality of fluid output channels.

10. The method of claim 1, wherein said endoscope connector comprises a single connector for connecting said plurality of fluid channels with said plurality of fluid output channels.
