Abstract
Retractor for insertion in an incision of a patient includes a frame defining a central opening and a reference plane, and at least one blade disposed within the central opening. The blade operatively coupled to the frame by a support structure for movement in a first direction generally laterally with the reference plane between an unretracted position and a retracted position, a second direction at an angle extending through and relative to the reference plane for adjustment of the blade depth, and a third direction rotationally relative to the reference plane. Additionally, the frame includes a track in mating relationship with the support structure for sliding movement therebetween in a defined relationship relative to the reference plane. Retractor assembly includes the retractor as previously described, in combination with an adjustment tool or an insertion tool.
