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.

A surgical sheath comprising:
- a conical section having a larger conical section first end tapering to a smaller conical section second end, with the larger conical section first end forming a proximal opening of the surgical sheath;
- an angle section having an irregular quadrilateral cross-sectional shape, and the smaller conical section second end joined to a first side of the angle section;
- a body section having a larger body section first end tapering to a smaller body section second end, with a second side of the angle section joined to the body section second end, and with the conical section having the proximal opening in a plane at an acute angle to a central axis of the body section, wherein the angle section further comprises a third side and a fourth side, wherein none of the sides of the angle section are parallel to each other;
- and
- with the body section having a first length and the conical section having a second length, and with the first length at least twice the second length, and with the conical section, the angle section and the body section comprising a molded one-piece unit of flexible material to allow the sheath to conform to inner walls of a patient's nostril.
