Abstract
A tissue dissector includes a handle portion and a head portion. The handle portion includes an actuation assembly having an actuator. The head portion includes an annular body having a blade assembly rotatably supported in the annular body. The blade assembly includes a blade member defining an aperture configured to receive tissue therethrough. The blade member is operatively coupled with the actuator for rotation about a central axis defined by the aperture. The handle portion and the head portion define a longitudinal axis that is disposed at an angle relative to the central axis.

A tissue dissector comprising:
- a handle portion including an actuation assembly having an actuator;
- and
- a head portion including an annular body having a blade assembly rotatably supported in the annular body, the blade assembly including a blade member defining an aperture configured to receive tissue therethrough, the blade member operatively coupled with the actuator for rotation about a central axis defined by the aperture,
- wherein:
- the handle portion and head portion define a longitudinal axis that is disposed at an angle relative to the central axis,
- the blade assembly further includes a blade gear secured with the blade member for concomitant rotation therewith, the blade gear operatively coupled with the actuator of the actuation assembly,
- the blade member includes a support portion and a blade portion extending from the support portion, the support portion in a planar contact with the blade gear, and
- the head portion further includes a third bearing configured to engage the blade portion of the blade member, wherein the third bearing defines an acute angle with respect to an axis extending through the aperture.
