Blunt Dissector for Separating Blood Vessels from Surrounding Tissue

摘要

A blunt dissector (11) for separating a blood vessel from surrounding tissues in a body comprises a longitudinal rod (16) having a proximal end, a distal end, and an internal passage for conducting insufflation gas between the proximal and distal ends. An interior sleeve (23) is mounted within the longitudinal rod (16) for receiving an endoscope (10) at the proximal end. A transparent tip (18) is mounted to the distal end of the longitudinal rod (16). A handle (17) is mounted to the proximal end of the longitudinal rod (16). The longitudinal rod (16) has an outer surface along substantially all of the longitudinal rod (16) between the proximal and distal ends consisting essentially of a fluoropolymer.
