Lateral retractor system and methods of use

摘要

Technology disclosed herein relates to retractors and methods of use for surgical procedures, and in particular, spinal surgical procedures. In one embodiment, a surgical refractor 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.

1. A surgical retractor comprising:
a pair of pivotable armatures configured to rotate from a first position to a second position, each pivotable armature terminating on a posterior end in a worm gear mechanism; a translatable armature configured to translate from a third position to a fourth position; a body for supporting the pair of pivotable armatures and the translatable armature; and a handle connected to the body comprising:
a first rotary actuator, operable to move the pair of pivotable armatures in opposite arcuate directions; anda second rotary actuator on a common rotational axis with the first rotary actuator, the second rotary actuator operable to translate the translatable armature in a linear direction,wherein rotation of the first rotary actuator moves the pair of pivotable armatures in opposite arcuate directions to any position between the first position and the second position while the translatable armature remains stationary, and wherein rotation of the second rotary actuator linearly translates the translatable armature into any position between the third position and the fourth position while the pair of pivotable armatures remain stationary.
