Abstract
Abstract A device for positioning components within endoscopic systems comprises a hermetically sealed housing. An outer ring element is mounted to rotate about the outer side of said housing and carries on its circumference at least one outer magnet. Further, an inner ring element is mounted inside said housing and carries likewise at least one inner magnet, said magnets being aligned in such a way that any rotation of said outer ring element has the effect to move said at least one inner magnet by magnetic coupling, such movement serving the purpose to position said respective components. In order to achieve a simple, relatively small and functionally safe structure it is proposed that both, said outer and said inner ring elements be configured as axially non-displaceable rings carrying said oppositely arranged magnets, and that said inner ring be mechanically connected with said component to be positioned.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
193 words
A device for positioning components within endoscopic systems, comprising: a housing hermetically sealed and having an outer side; an outer ring element mounted to rotate about said outer side of said housing and carrying on its circumference at least one outer magnet; an inner ring element mounted inside said housing and carrying at least one inner magnet; a component positioned inside said housing; said at least one inner magnet and said at least one outer magnet being arranged such that any rotation of said outer ring element effects movement of said at least one inner magnet by magnetic coupling, such movement serving the purpose to axially position said component; wherein said outer and said inner ring elements, are configured as rotatable, but axially nondisplaceable rings carrying oppositely arranged said at least one inner magnet and said at least one outer magnet; wherein said inner ring is mechanically connectable with said component to be positioned; and wherein said inner ring is connectable, via a thread, with said component arranged for axial displacement in said housing so that any rotary movement of said inner ring will be translated into an axial movement of said component.
Claim 2
Independent Claim
193 words
A device for positioning components within endoscopic systems, comprising: a housing hermetically sealed and having an outer side; an outer ring element mounted to rotate about said outer side of said housing and carrying on its circumference at least one outer magnet; an inner ring element mounted inside said housing and carrying at least one inner magnet; a component positioned inside said housing; said at least one inner magnet and said at least one outer magnet being arranged such that any rotation of said outer ring element effects movement of said at least one inner magnet by magnetic coupling, such movement serving the purpose to axially position said component; wherein said outer and said inner ring elements, are configured as rotatable, but axially nondisplaceable rings carrying oppositely arranged said at least one inner magnet and said at least one outer magnet; wherein said inner ring is mechanically connectable with said component to be positioned; and wherein said inner ring is connectable, via a thread, with said component arranged for axial displacement in said housing so that any rotary movement of said inner ring will be translated into an axial movement of said component.
