Abstract
A monopolar needle assembly comprises a disposable insulated needle having an uninsulated tip projecting from a needle stem and a sheath for covering the needle. The protective sheath is preferably plastic and injection molded. The needle is disposed within a protective sheath until the needle is inserted into the patient, thereby preventing contamination of the needle. As embodied herein, the exterior and interior surfaces of the protective sheath are tapered to conform essentially to the elongated configuration of the needle. The portion of the sheath proximate the needle stem includes flanges projecting from the exterior of the sheath to prevent the monopolar needle assembly of the present invention from rolling if it is dropped.
