Telescoping blade assembly and instruments for adjusting an adjustable blade

摘要

A retractor blade assembly includes a fixed blade having a longitudinal axis and an adjustable blade operatively coupled to the fixed blade and adjustable relative to the fixed blade along the longitudinal axis of the fixed blade. The adjustable blade may include a flexible tab that is movable between a first position, in which the tab is generally co-planar to the adjustable blade, and a second position, in which the tab is oriented generally transverse to the adjustable blade.
