Abstract
Abstract The invention comprises a surgical retractor having a barrel with a distal end and a handle. A plurality of retractor pods are located at a plurality of angles and positions on the lateral periphery of the barrel. The retractor pods are movable between a retracted position in which the pods are substantially flush with the surface of the barrel and an extended position in which each pod outwardly and laterally projects from the barrel. The handle is operatively connected to the pods to move the pods between the retracted and extended positions.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
146 words
A surgical retractor comprising a barrel having a distal end and handle located opposite the distal end of said barrel, a plurality of retractor pods located at a plurality of angles and positions on the lateral periphery of the barrel, the retractor pods being movable between a retracted position in which the pods are substantially flush with the surface of the barrel and an extended position in which each pod is outwardly and laterally projected from the barrel. the handle being operatively connected to the pods to move the pods between the retracted and extended positions, wherein the handle comprises a trigger and a grasping member, the trigger being pivotable with respect to the grasping member, and further comprising flexible, resilient fibers positioned substantially within the barrel having opposite ends connected to the trigger at one end and to a retractor pod at the opposite end.
Claim 2
Dependent Claim
146 words
A surgical retractor comprising a barrel having a distal end and handle located opposite the distal end of said barrel, a plurality of retractor pods located at a plurality of angles and positions on the lateral periphery of the barrel, the retractor pods being movable between a retracted position in which the pods are substantially flush with the surface of the barrel and an extended position in which each pod is outwardly and laterally projected from the barrel. the handle being operatively connected to the pods to move the pods between the retracted and extended positions, wherein the handle comprises a trigger and a grasping member, the trigger being pivotable with respect to the grasping member, and further comprising flexible, resilient fibers positioned substantially within the barrel having opposite ends connected to the trigger at one end and to a retractor pod at the opposite end.
Claim 3
Dependent Claim
20 words
The surgical retractor of claim 1 wherein the fibers are biased toward curving outward from the surface of the barrel.
Claim 4
Dependent Claim
26 words
The surgical retractor of claim 1 further comprising bias means for biasing the trigger and the fibers so the retractor pods are in the retracted position.
Claim 5
Dependent Claim
13 words
The surgical retractor of claim 3 wherein the bias means comprises a spring.
