Abstract
Devices and methods are provided for assisting in spinal stabilization. An access device is provided that includes an outer sleeve, inner sleeve, spring latch and lock nut. The inner sleeve includes compressible grasping elements. The access device can be coupled to a screw head by sliding the outer sleeve relative to the inner sleeve and compressing the grasping elements. The coupled access device and screw can then be delivered to a target location in a patient. After providing two or more access devices, a rod member can be delivered using a rod insertion device. The rod member can serve as a connection between the two screws, and can provide spinal stabilization. An anti-torque device and a persuading device can be used to help ensure that the rod member is placed and secured in a proper location within a patient.
