Abstract
Systems, devices, and methods for providing a surgeon with improved viewing angles during arthroscopic surgical procedures are provided. In some embodiments, a cannula is provided that includes an elongate body that can extend along a longitudinal axis, the body having a proximal end, a distal end, a lumen extending through the body between openings at the proximal and distal ends. The cannula can have a first flange member that can extend at least partially around at least one of the openings, and the first flange member can have a distal-facing surface, where at least a portion of the distal-facing surface can be reflective.
Claims18
A cannula, comprising:
- an elongate body extending along a longitudinal axis, the body having a proximal end, a distal end, and a lumen extending through the body between openings at the proximal and distal ends;
- and
- a first flange member that extends at least partially around at least one of the openings, the first flange member having a first surface, wherein at least a portion of the first surface is reflective;
- wherein an angle at which the first flange member is oriented relative to the longitudinal axis of the body is adjustable.
A surgical method, comprising:
- advancing a cannula through a first portal to a target site in a patient's body;
- advancing an imaging device comprising at least one image sensor through a second portal towards the target site;
- performing a surgical function at the target site;
- and
- viewing a result of the surgical function with the imaging device by directing the imaging device at a reflective surface of the cannula that displays a reflected image of the result of the surgical function at the target site.
