Abstract:
1. A retractor comprising: a base; a first wall extending from the base, the first wall defining a longitudinal axis and extending between a first end and a second end, the first wall further defining at least a portion of a longitudinal cavity and a second cavity disposed at the first end; a rotatable shaft including an outer surface defining a groove, at least a portion of the shaft being disposed with the longitudinal cavity, the shaft including a head for disposal in the second cavity; a blade being disposed for movement along the longitudinal cavity; a post connected with the blade and disposed with the groove such that rotation of the shaft causes axial translation of the blade relative to the first wall between a first orientation and a second orientation, the post extending perpendicular to the longitudinal axis; and a cap configured to snap into engagement with a cavity in the base, the cap including a bottom surface defining a first spine surface, the head including a second spline surface that engages the first spline surface such that rotation of the shaft is prevented upon fixation of the second spline surface with the base, the cap preventing the shaft from moving proximally along the longitudinal axis.
