TISSUE RETRACTION AND VERTEBRAL DISPLACEMENT DEVICES, SYSTEMS, AND METHODS FOR POSTERIOR SPINAL FUSION |
摘要 |
Devices for retracting tissue during a minimally-invasive, posterior spinal fusion procedure include a blade positionable along a passageway device connected to a connecting element implanted in a vertebra of the spine, such that the blade covers at least a portion of a longitudinal opening of the passageway device. The blade may be coupled to the passageway device by receiving the passageway device with a receiving portion. Systems for displacing the vertebrae of the spine include first and second extenders, the distal ends of each of which are configured to engage the connecting elements. Each extender may include a shaft configured to be securely engaged within a cage of the respective connecting element. The devices and systems of the present invention may be used in connection with an interbody fusion technique performed through an opening extending between the passageway devices, and an intermediate retractor blade may provide additional tissue retraction. |
