Abstract
A surgical sheath for use in endoscopic trans-nasal or intra-ocular surgery has an angle section joined to a conical section, with the conical section having a central axis not parallel to a central axis of the angle section. A body section is joined to the angle section, with the body section having a length at least twice the length of the angle section. The conical section, the angle section and the body section may be a flexible or compliant material. The sheath reduces collateral trauma to the tissues in the surgical pathway.
