Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
74 words
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.
Claim 2
Dependent Claim
74 words
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.
Claim 3
Dependent Claim
15 words
The combination of claim 1 in which each control handle includes a light guide inlet.
Claim 4
Dependent Claim
26 words
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.
Claim 5
Dependent Claim
18 words
The combination of claim 3 in which said light guide inlets and outlets are separable and quick operating.
Claim 6
Dependent Claim
23 words
The combination of claim 2 in which said connector means includes at least one light guide inlet communicating with a source of light.
Claim 7
Dependent Claim
15 words
The combination of claim 5 in which all light guide inlets are of uniform configuration.
Claim 8
Dependent Claim
22 words
The combination of claim 1 in which the light means is bifurcated in said connector means to facilitate servicing each shaft means.
Claim 9
Dependent Claim
15 words
The combination of claim 1 in which the light means defines a fiber optic bundle.
Claim 10
Dependent Claim
23 words
The combination of claim 8 in which the fiber optic bundle is bifurcated in said connector means to facilitate servicing each shaft means.
Claim 11
Dependent Claim
78 words
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.
Claim 12
Dependent Claim
16 words
The combination of claim 10 in which the locking means includes seal means and friction means.
Claim 13
Dependent Claim
23 words

Claim 14
Independent Claim
63 words
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.
Claim 15
Independent Claim
63 words
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.
Claim 16
Dependent Claim
16 words
