1. A method of using a surgical retractor, the method comprising:
- providing or obtaining a surgical retractor including a handle having a first actuator and a second actuator, a plurality of blades rotatable relative to the handle between a first closed position and a first open position and supported by a plurality of arms coupleable to the handle, and a translatable blade that is translatable relative to the handle between a second closed position and a second open position;
inserting the plurality of blades and the translatable blade simultaneously into a corridor, the inserting performed with the plurality of blades in the first closed position and the translatable blade in the second closed position;
rotating the first actuator about a rotational axis of the first actuator to actuate a rotating drive mechanism along the rotational axis, the rotating drive mechanism directly coupled to a first arm and a second arm of the plurality of arms, the first arm to pivot a first blade of the plurality of blades about a first pivot point and the second arm to pivot a second blade of the plurality of blades about a second pivot point to the first open position; and
actuating the second actuator to linearly translate the translatable blade to the second open position.

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 armature in a linear direction.

13. A method comprising:
-
performing operations using a surgical retractor, the surgical retractor including a handle having a first actuator and a second actuator, a plurality of blades rotatable relative to the handle from a first closed position to a first open position and supported by a plurality of armatures coupleable to the handle, and a translatable blade that is translatable relative to the handle from a second closed position to a second open position, the operations comprising; inserting the plurality of blades and the translatable blade simultaneously into a corridor, the inserting performed with the plurality of blades in the first closed position and the translatable blade in the second closed position; actuating the first actuator to rotate a drive about a single rotational axis of the drive to directly drive a first armature of the plurality of armatures to pivot a first blade of the plurality of blades about a first pivot point to the first open position; and
to directly drive a second armature of the plurality of armatures to pivot a second blade of the plurality of blades about a second pivot point to the first open position, wherein the first pivot point and the second pivot point are each offset from a medial longitudinal axis of the surgical retractor; andactuating the second actuator to linearly translate the translatable blade to the second open position. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
