Abstract
A cutting instrument comprising: an outer tube comprising a distal end and a proximal end; an inner tube rotatably disposed within said outer tube, said inner tube comprising a distal end, a proximal end and a region intermediate said distal end and said proximal end, said region comprising a plurality of slits formed in said inner tube so as to render said region of said inner tube flexible; and a bellows disposed adjacent to said plurality of slits so as to render said region of said inner tube fluid-tight.
Claims19
A cutting instrument comprising:
- an outer tube comprising a distal end and a proximal end;
- an inner tube rotatably disposed within the outer tube, the inner tube comprising a distal end, a proximal end and an intermediate region between the distal and proximal ends of the inner tube, the intermediate region comprising a plurality of slits formed in the inner tube so as to render the intermediate region of the inner tube flexible;
- and
- a bellows configured to cover at least a portion of the intermediate region of the inner tube so as to render the intermediate region fluid-tight, wherein the bellows is disposed exterior to the inner tube and interior to the outer tube, and further wherein the bellows comprises a helical bellows so as to provide a helical passageway for fluid between the bellows and the outer tube.

A cutting instrument comprising:
- an outer tube including a distal end and a proximal end;
- an inner tube disposed within and rotatable relative to the outer tube, the inner tube including a distal end, a proximal end and a region intermediate of the inner tube, the region comprising a plurality of slits formed in the inner tube so as to render the region of the inner tube flexible;
- and
- a helical bellows configured to cover at least a portion of the region of the inner tube where the plurality of slits are formed to render the region of the inner tube with the plurality of slits fluid tight, the bellows providing a helical passageway for fluid between a helical passageway between the bellows and the outer tube.

A cutting instrument comprising:
- an outer tube;
- an inner tube rotatably disposed within the outer tube and including a flexible region defined by a plurality of slits formed in the inner tube;
- and
- a helical bellows configured to cover the flexible region of the inner tube where the plurality of slits are formed to render the flexible region fluid tight, the bellows providing a helical passageway for fluid between the bellows and the outer tube.
