Abstract

Piggyback endoscopes are disclosed which are connected together releasably where the scopes receive illumination from a single light source via a single fiber optic bundle which has been divided into at least two branches, one branch being individual to each scope.

Claims

1. In combination, a plurality of endoscopes comprising:

a primary or parent endoscope including a first control handle and a cooperating first shaft means,

a secondary or companion endoscope including a second control handle and a cooperating second shaft means,

connector means joining the first and second control handles, and

light means having a single light source for illuminating said first and second shaft means, said connector means providing a housing for said light means.

2. The combination of claim 1 in which each control handle includes a light guide inlet.

3. The combination of claim 2 in which the connector means is a rigid member and includes light guide outlet connectors mating with said light guide inlets.

4. The combination of claim 3 in which said light guide inlets and outlets are separable and quick operating.

5. The combination of claim 2 in which said connector means includes at least one light guide inlet communicating with a source of light.

6. The combination of claim 5 in which all light guide inlets are of uniform configuration.

7. The combination of claim 1 in which the light means is bifurcated in said connector means to facilitate servicing each shaft means.

8. The combination of claim 1 in which the light means defines a fiber optic bundle.

9. The combination of claim 8 in which the fiber optic bundle is bifurcated in said connector means to facilitate servicing each shaft means.

10. The combination of claim 3 in which the connector means light outlets and the first and second control handle light inlets are formed with cooperating, separable locking means, said locking means comprising a key slot formed on one of each said outlet and each said inlet and a cooperating lug formed on the other of each said outlet and each said inlet whereby said first and second control handles are fixed relative to one another when connected together.

11. The combination of claim 10 in which the locking means includes seal means and friction means.

12. The combination of claim 1 in which the first control handle is formed with a channel opening for receiving the second shaft means.

13. A method of supplying at least two endoscopes each having a flexible shaft with illumination from a single light source comprising the steps of:

providing a single light source,

providing light transmission means,

dividing the light transmission means into at least two branches, and

connecting one branch to each endoscope individually whereby each endoscope is illuminated by means of said single light source.

14. The method of claim 13 in which the light transmission means is a fiber optic bundle.

15. The method of claim 13 plus the steps of providing connector means for connecting said endoscopes together releasably and dividing the light transmission means within the connector means.

16. The method of claim 13 plus the step of providing a channel inlet in one endoscope for receiving the shaft of the other endoscope.
