    摘要： Methods and devices are provided for facilitating delivery and implanting of a bone anchor into bone. In one exemplary embodiment, a bone anchor extension is provided for coupling to a bone anchor to facilitate delivery and implanting of the bone anchor in bone. The bone anchor extension can have a generally elongate configuration that allows it to extend from a skin incision in a patient to a site proximate a patient's spine, and it can include a lumen extending therethrough between proximal and distal ends thereof. A distal end of the bone anchor extension can be adapted to engage a bone anchor, such as a bone screw. Various techniques are provided for locking the distal end of the bone anchor extension into engagement with a bone anchor.

    摘要： An instrument for adjusting a spinal rod relative to a bone anchor includes a handle connecting a set screw driver with a reduction collar. The handle includes an inner shaft engageable with the set screw driver, an outer shaft engageable with the reduction collar, and a clutch connecting the inner shaft to the outer shaft and permitting selective rotation of the inner shaft relative to the outer shaft, and thus, selective rotation of the set screw driver relative to the reduction collar, upon application of a torque to the reduction collar and the outer shaft greater than a preselected torque value.

    摘要： A spinal fixation element fixation reduction system is provided herein. In general, the system can include a cap element with a bore having a central axis extending therethrough wherein the cap element is configured to releasably engage any type of surgical device (e.g., an access sleeve, a vertebral body rotator, etc.). Further, the system can include a driver configured to be slidably and removably positioned through the cap element. The system can also include an actuator configured to apply a force to the driver substantially along the central axis of the cap element thereby moving the driver in a distal direction so as to effect reduction of a spinal fixation element into a bone anchor. Additionally, a method of reducing a spinal fixation element into a bone anchor is also provided wherein the method can be performed as a minimally invasive surgical procedure or as an open procedure.

    摘要： The present invention provides minimally invasive devices and methods for delivering a spinal connector to one or more spinal anchor sites in a patient's spinal column. In one embodiment, a spinal implant and access device is provided that includes a U-shaped receiver member, a bone-engaging member, and an extension member. The U-shaped receiver member can have a recess formed therein that is adapted to seat a spinal connector. The bone-engaging member can extend distally from the receiver member and it can be adapted to engage bone to thereby mate the receiver member to bone. The extension member can extend proximally from the receiver member and it can include a frangible portion formed thereon that is adapted to break when a predetermined force is applied thereto thereby allowing at least a portion of the extension member to be separated from the receiver member.

    摘要： Disclosed herein are devices and methods for removing tissue. In one aspect, a device for removing tissue includes a hollow elongate member having an outer wall and a lumen, a selectively deployable tissue-cutting element extending from the hollow elongate member, and an actuation member extending through the lumen and coupled to the hollow elongate member at a location that is distal to the tissue-cutting element. Movement of the actuation member can cause the tissue-cutting element to move from the insertion configuration where the tissue-cutting element is not deployed to a tissue-cutting configuration where the tissue-cutting element is deployed such that it is radially extended relative to the insertion configuration.
