<p>A self-supporting retractor (10) for holding open an anatomic space for performing endoscopic surgical procedures. The retractor includes a substantially rigid elongate member (12) having proximal (14) and distal ends (16) having a 'C' cross section, defining a passage (18) and a longitudinal working window (20) along the retractor. The distal end (16) is preferably rounded to facilitate insertion along a dissected space with minimized tissue trauma, and may include a hooded portion (80) enclosing the passage at the distal end. The elongate member (12) may include radially-cooperating segments or edges to maximize the area of the space held open by the retractor. The retractor may include a handle or a pivotal finger grip (94) on the proximal end (14) to manipulate the retractor during use, and/or a curved handle (32) to tent the incision providing access to the dissected space. The retractor may also include a channel member (40) for an endoscope, integrally formed or pivotally attached to the retractor.</p> |
