Godlevsky Enterprises, LLC ~ Cliff Godlevsky ~ Call /Text or whatsapp: 5207090315 I have two identical sets available!! Zimmer Biomet WalterLorenz WA300 Surgical Assist Arm Universal 22pc Instrument Sets. These sets are complete with 7 instrument holders, 13 retractor blades, grasping forceps with original case w/ tray & lid. All instuments look brand new with no sign of use. Very hard to find a set like this on ebay so I suggest buying them both if you need them. This is for the Universal Instrument Sets only, the Surgical Assist Arm is not included. Guaranteed not to be DOA. These instruments are compatible with the WalterLorenz Surgical Assist Arm by Zimmer Biomet which is a bionic, electromechanical device designed to enhance operating room efficiency by providing stable, fatigue-free retraction and instrument positioning.
