Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
173 words
An endoscope, comprising: a shaft having a longitudinal axis, a distal end and a proximal end; a handle disposed at said proximal end of said shaft and extending sidewards of said shaft, said handle being configured in pistol-like fashion; a mechanism for pivoting a view direction of said endoscope within an observation area; and at least two operating elements which are operatively engaged with said mechanism for actuating said mechanism, a first one of said at least two operating elements being for pivoting said view direction with respect to said longitudinal axis of said shaft and the second one of said at least two operating elements being for pivoting said view direction in circumferential direction, said first operating element being disposed on a front side of said handle such that it is operable with at least one finger of the hand holding said handle, wherein said second operating element is disposed on a side face of said handle such that it is operable with the thumb of said same hand holding said handle.
Claim 2
Dependent Claim
173 words
An endoscope, comprising: a shaft having a longitudinal axis, a distal end and a proximal end; a handle disposed at said proximal end of said shaft and extending sidewards of said shaft, said handle being configured in pistol-like fashion; a mechanism for pivoting a view direction of said endoscope within an observation area; and at least two operating elements which are operatively engaged with said mechanism for actuating said mechanism, a first one of said at least two operating elements being for pivoting said view direction with respect to said longitudinal axis of said shaft and the second one of said at least two operating elements being for pivoting said view direction in circumferential direction, said first operating element being disposed on a front side of said handle such that it is operable with at least one finger of the hand holding said handle, wherein said second operating element is disposed on a side face of said handle such that it is operable with the thumb of said same hand holding said handle.
Claim 3
Dependent Claim
17 words
