"A ""plate blade without teeth"" is a type of surgical instrument that is part of a larger class of devices, often referred to as retractors or spreaders. It is used in a variety of surgical procedures to separate, retract, and hold tissue or bone, providing the surgeon with a clear view of the surgical field."
A distal component of a surgical retraction system, surgical retractor, and/or surgical instrument assist arm system designed to function as a parting edge to separate the margins of a wound/incision during a surgical procedure. It is intended to be attached to the frame (e.g., mounting ring/bar) of a surgical retraction system, or may be fixed onto a retractor handle; it does not include a handle. It is a metal device, sometimes referred to as a variable or vario retractor blade when assembled with a separate retractor handle, because it is available in a variety of lengths and sizes. This is a reusable device.
