1. A surgical retractor positioning device, comprising:
- a) a frame;
b) an arm connected to the frame, the arm including a proximal end, a distal end having a distal end axis, and a major axis, the distal end axis being movable relative to the proximal end, whereby the distal end axis can intersect the major axis at an angle;
c) at least one blade connected to the distal end of the arm, the blade being fixably rotatable about the major axis; and
d) a retractor blade assembly that releases the blade from the blade assembly onto the distal end of the arm.

Abstract
A surgical retractor positioning device is provided to create a surgical working field in a minimally invasive and flexible manner. In one embodiment, the device can include a frame and an arm connected to the frame. The arm can include a proximal end, a distal end having a distal end axis, and a major axis, wherein the distal end axis is movable relative to the proximal end, whereby the distal end axis can intersect the major axis at an angle. The device can include at least one blade connected to the distal end of the arm, wherein the blade is fixably rotatable about the major axis. The device can include at least two arms.

26. A surgical retractor positioning device, comprising:
-
a) a circular frame; b) a plurality of arms connected to the frame, each arm including a proximal end, a distal end having a distal end axis being movable relative to the proximal end, and a major axis that extends between the proximal and distal ends, whereby the distal end axis can intersect the major axis at an angle, the major axis of at least one arm being able to pivot about a point at the frame; and c) a retractor blade connected to the distal end of each arm, each blade being fixably rotatable about the major axis. - View Dependent Claims (27, 28)

29. A method of forming a surgical working field in a patient, comprising the steps of:
-
making an incision in a patient; releasing a plurality of blades from a retractor blade assembly onto distal ends of arms of a surgical retractor, each arm of the surgical retractor including a major axis, a proximal end, and a distal end having a distal end axis, the distal end axis being movable relative to the proximal end, whereby the distal end axis can intersect the major axis at an angle, the blades being adjustable from a collapsed, reduced diameter configuration to an extended, increased diameter configuration; positioning the surgical retractor over the incision; introducing the blades in the collapsed configuration into the incision in the patient; expanding the blades within the incision to the increased configuration to create the working field in the patient; and rotating at least one blade relative to a major axis of an arm and affixing the blade in a desired position. - View Dependent Claims (30)
