Abstract

This invention includes surgical retractors that comprise an expandable frame that includes at least two base components, a connector, and at least two retractor blades attached to the expandable frame. Also included are surgical retractors that comprise a housing component that includes a cylindrical portion and a contiguous blade portion, assemblies comprising a surgical retractor assembled to at least one obtruator, illuminated surgical cannulas, and methods of using the same during a surgical procedure.

First claim

What is claimed is:

1. A surgical retractor, comprising:
a first retractor blade and a second retractor blade;
a first connector assembled to a proximal end of the first retractor blade and a proximal end of the second retractor blade, wherein at least the first retractor blade or the second retractor blade is movable along a line that is parallel to a length of the first connector;
a third retractor blade and a fourth retractor blade; and
a second connector assembled to a proximal end of the third retractor blade and a proximal end of the fourth retractor blade, wherein at least the third retractor blade or the fourth retractor blade is movable along a line that is parallel to a length of the second connector, and wherein at least the first connector or the second connector is movable along a line that intersects the first connector and the second connector;
wherein the second and fourth retractor blades move together with respect to the first and third retractor blades.

2. The retractor of claim 1 , wherein the first connector or second connector is curved.

3. The retractor of claim 1 , wherein the first retractor blade or second retractor blade is attached to a base component and the base component is attached to the first connector.

4. The retractor of claim 1 , wherein the retractor blades are movable to a position in which the blades collectively define a conduit.
