1. 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 the translatable armature.

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.

12. 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, each of the first armature and the second armature further comprising a set of gear teeth disposed along an arcuate surface to interface with the first actuator; and a second actuator coupled to the retractor body and actuatable to linearly translate the translatable armature. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
