Premium Jansen Self-Retaining Mastoid Retractor with Thumbscrew Lock

The Jansen Retractor featured in Images is a specialized, compact medical instrument heavily relied upon in ENT (Ear, Nose, and Throat) surgery, mastoidectomies, neurosurgery, and small orthopedic procedures. It is explicitly engineered to separate and stabilize tough skin edges and subcutaneous layers within small or shallow surgical locations, providing surgeons with a rock-steady, hands-free workspace.

This instrument stands out due to its precise mechanical design. Instead of standard finger ring handles and click-ratchet steps, it utilizes an ultra-compact cross-bar frame adjusted via a smooth, threaded rear thumbscrew. Turning the flat key allows fine, microscopic incremental widening to exact dimensions without risking over-tensioning.

Key Features:

• Asymmetric 3×3 Prong Configuration: Designed with 3 specialized interlocking prongs per side (featuring sharp hooks on one arm and flatter, securing teeth on the other) to provide optimal multi-angle bone or tissue traction without slipping.

• Threaded Thumbscrew Expansion Lock: The fine-threaded turn-key mechanism provides micro-adjustable retraction tension that will not slide or jump teeth during delicate microsurgery.

• Medical-Grade Stainless Steel Build: Forged from high-tensile, premium clinical steel that highly resists rusting, pitting, and chemical stress over decades of clinical utilization.
