Abstract
A surgical sheath for use in endoscopic trans-nasal or intra-ocular surgery has first and second attachment fittings on opposite side of a conical section used for attaching individual sheaths to form a sheath pair. The sheaths of the pair can mutually support each other during surgery, to better resist inadvertent displacement of the sheaths. After the sheaths are positioned, the conical sections of the sheaths may be attached together using clips, pins, belts or other techniques. The sheaths reduce collateral trauma to the tissues in the surgical pathway.
