Abstract
Technology disclosed herein relates to retractors and methods of use for surgical procedures, and in particular, spinal surgical procedures. In one embodiment, a surgical retractor includes a pair of pivotable armatures and a translatable armature. A body for supporting the armatures is provided, with a handle connected thereto. The handle includes a first rotary actuator, wherein a rotation of the first rotary actuator moves the pair of pivotable armatures in opposite arcuate directions, and a second rotary actuator, wherein a rotation of the second rotary actuator translates the translatable at nature in a linear direction.

21. A surgical retractor comprising:
-
a retractor body; a first armature pivotably coupled to the retractor body at a first pivot point, the first armature rotatable between a first closed position and a first open position; a second armature pivotably coupled to the retractor body at a second pivot point spaced apart from the first pivot point, the second armature rotatable between a second closed position and a second open position; a translatable armature disposed between the first pivot point and the second pivot point, the translatable armature translatable between a third closed position and a third open position; a first actuator coupled to the retractor body and aligned with the translatable armature; a worm drive coupled to the first actuator, the first actuator rotatable to rotate the worm drive to operate the first armature and the second armature independent of the translatable armature; and a second actuator coupled to the retractor body and rotatable to linearly translate translatable armature. - View Dependent Claims (22, 24, 25, 26, 27, 28, 29, 30, 31)

32. A surgical retractor comprising:
-
a retractor body; a first armature coupled to the retractor body at a first pivot point, the first armature pivotable between a first closed position and a first open position; a second armature coupled to the retractor body at a second pivot point spaced apart from the first pivot point, the second armature pivotable between a second closed position and a second open position; a translatable armature disposed along a longitudinal axis running between the first pivot point and the second pivot point, the translatable armature translatable between a third closed position and a third open position; a first actuator coupled to the retractor body and aligned along the longitudinal axis, the first actuator actuatable to operate the first armature and the second armature independent of the translatable armature; and a second actuator coupled to the retractor body and actuatable to linearly translate the translatable armature. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41)

42. A surgical retractor comprising:
-
a retractor body; a first arm coupled to the retractor body at a first pivot point, the first arm movable about the first pivot point between a first closed position and a first open position; a first drive coupler connected to the first arm and including a first set of gear teeth disposed along an arcuate surface; a second arm coupled to the retractor body at a second pivot point spaced apart from the first pivot point, the second arm movable about the second pivot point between a second closed position and a second open position; a second drive coupler connected to the second arm and including a second set of gear teeth disposed along an arcuate surface; a translatable arm that is translatable between a third closed position and a third open position; a first actuator coupled to the retractor body and substantially aligned with the translatable arm; a drive mechanism coupled to the first actuator and interfacing with the first set of gear teeth and the second set of gear teeth, the drive mechanism actuated by rotation of the first actuator to operate the first arm and the second arm independent of the translatable arm; and a second actuator coupled to the retractor body and rotatable to operate the translatable arm. - View Dependent Claims (43)
