Abstract
Abstract In an endoscope with a camera objective, in particular a video camera objective, coupled to the eyepiece cup of the endoscope at its proximal end, the objective is mounted so that it is free to rotate on the proximal end of the eyepiece cup. The camera objective and its camera head have a center of gravity which is offset from the axis of rotation of the objective so that the objective maintains its orientation if the endoscope is rotated about its longitudinal axis, whereby such rotation of the endoscope does not affect the endoscopic picture displayed on a monitor of the video camera.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
105 words
An endoscope having a longitudinal axis and a proximal end with an objective of a camera releasably coupled thereto, wherein the objective is coupled to said proximal end so as to be capable of free rotation thereon about an axis of rotation, the center of gravity of those camera components which are connected to the endoscope being offset with respect to said axis of rotation such that gravity exclusively maintains the angular orientation of the objective by pendulum action when the endoscope is rotated about said longitudinal axis, the endoscope having a downwardly directed pendulum connected to said objective for offsetting said center of gravity.
Claim 2
Dependent Claim
105 words
An endoscope having a longitudinal axis and a proximal end with an objective of a camera releasably coupled thereto, wherein the objective is coupled to said proximal end so as to be capable of free rotation thereon about an axis of rotation, the center of gravity of those camera components which are connected to the endoscope being offset with respect to said axis of rotation such that gravity exclusively maintains the angular orientation of the objective by pendulum action when the endoscope is rotated about said longitudinal axis, the endoscope having a downwardly directed pendulum connected to said objective for offsetting said center of gravity.
Claim 3
Dependent Claim
108 words
An endoscope having a longitudinal axis and a proximal end with an objective of a camera releasably coupled thereto, wherein the objective is coupled to said proximal end so as to be capable of free rotation thereon about an axis of rotation, the center of gravity of those camera components which are connected to the endoscope being offset with respect to said axis of rotation such that gravity exclusively maintains the angular orientation of the objective by pendulum action when the endoscope is rotated about said longitudinal axis, the endoscope having two downwardly angled stabilizers located on a mounting of the objective for offsetting said center of gravity.
Claim 4
Dependent Claim
108 words
An endoscope having a longitudinal axis and a proximal end with an objective of a camera releasably coupled thereto, wherein the objective is coupled to said proximal end so as to be capable of free rotation thereon about an axis of rotation, the center of gravity of those camera components which are connected to the endoscope being offset with respect to said axis of rotation such that gravity exclusively maintains the angular orientation of the objective by pendulum action when the endoscope is rotated about said longitudinal axis, the endoscope having two downwardly angled stabilizers located on a mounting of the objective for offsetting said center of gravity.
Claim 5
Dependent Claim
112 words
An endoscope having a longitudinal axis and a proximal end with an objective of a camera releasably coupled thereto, wherein the objective is coupled to said proximal end so as to be capable of free rotation thereon about an axis of rotation, the center of gravity of those camera components which are connected to the endoscope being offset with respect to said axis of rotation such that gravity exclusively maintains the angular orientation of the objective by pendulum action when the endoscope is rotated about said longitudinal axis, the endoscope having an eyepiece cup provided with an annular grove, a mounting of the objective having a ball catch engaging in said groove.
Claim 6
Dependent Claim
112 words
An endoscope having a longitudinal axis and a proximal end with an objective of a camera releasably coupled thereto, wherein the objective is coupled to said proximal end so as to be capable of free rotation thereon about an axis of rotation, the center of gravity of those camera components which are connected to the endoscope being offset with respect to said axis of rotation such that gravity exclusively maintains the angular orientation of the objective by pendulum action when the endoscope is rotated about said longitudinal axis, the endoscope having an eyepiece cup provided with an annular grove, a mounting of the objective having a ball catch engaging in said groove.
Claim 7
Dependent Claim
113 words
An endoscope having a longitudinal axis and a proximal end with an objective of a camera releasably coupled thereto, wherein the objective is coupled to said proximal end so as to be capable of free rotation thereon about an axis of rotation, the center of gravity of those camera components which are connected to the endoscope being offset with respect to said axis of rotation such that gravity exclusively maintains the angular orientation of the objective by pendulum action when the endoscope is rotated about said longitudinal axis, the endoscope having an eyepiece cup provided with an annular groove, a screw mounted in a mounting of the objective engaging in the annular groove.
Claim 8
Dependent Claim
113 words
An endoscope having a longitudinal axis and a proximal end with an objective of a camera releasably coupled thereto, wherein the objective is coupled to said proximal end so as to be capable of free rotation thereon about an axis of rotation, the center of gravity of those camera components which are connected to the endoscope being offset with respect to said axis of rotation such that gravity exclusively maintains the angular orientation of the objective by pendulum action when the endoscope is rotated about said longitudinal axis, the endoscope having an eyepiece cup provided with an annular groove, a screw mounted in a mounting of the objective engaging in the annular groove.
Claim 9
Dependent Claim
26 words
