Abstract
An arthroscopy cannula according to an exemplary aspect of the present disclosure includes, among other things, a cannula body that extends along a longitudinal axis between a proximal end and a distal end and a first inflatable component attached to the cannula body and configured to move via fluid pressure between a compressed position and an expanded position.
Claims18
An arthroscopy cannula, comprising:
- a cannula body that extends along a longitudinal axis between a proximal end and a distal end;
- a first inflatable component attached to said cannula body at said proximal end and configured to move via fluid pressure between a compressed position and an expanded position;
- and
- a port formed in the cannula body and configured to allow a fluid to pass into the first inflatable component to lengthen the first inflatable component from the compressed position to the expanded position,
- wherein said first inflatable component lengthens in a direction that is parallel to said longitudinal axis of said cannula body,
- wherein said port is arranged such that said fluid passes through an inlet located at said distal end of said cannula body prior to passing through said port.
3 more elements
An arthroscopy cannula, comprising:
- a cannula body extending along a longitudinal axis between a proximal end and a distal end;
- a bowl portion of the cannula body positioned at the proximal end;
- a tube of the cannula body extending from the bowl portion to the distal end, wherein the bowl portion flares outwardly relative to the tube;
- a first inflatable component attached directly to the bowl portion and configured to move between a compressed position and an expanded position in response to receiving a fluid, wherein the first inflatable component is closer to the distal end of the cannula body when in the expanded position and is further from the distal end when in the compressed position;
- and
- a port formed in the bowl portion and configured to allow said fluid to pass into said first inflatable component to lengthen said first inflatable component from said compressed position toward said expanded position,
- wherein said first inflatable component lengthens in a direction that is parallel to said longitudinal axis of said cannula body,
- wherein an inlet that is configured to receive the fluid is located at the distal end of the cannula body, and the port is located remotely from the inlet.
