A self-retaining surgical tool for efficient soft tissue retraction in deep or constrained surgical areas is the B-Z Weitlaner Retractor, 90°. Its 90° downward-angled arms improve visibility and accessibility, especially during spine, orthopedic, or neurosurgery treatments. The retractor has a finger ring handle with a ratchet lock to maintain constant retraction without the need for physical labor, and 4x4 blunt prongs for safe yet delicate tissue engagement.
