摘要:
A fixation assembly having a driver, a holding sleeve, and an alignment mechanism is disclosed. The driver may include a driver body and a coupling extending from a distal end of the driver body. The holding sleeve may have a holding sleeve body, a channel extending through the holding sleeve body, and a fixation element coupler disposed at a distal portion of the holding sleeve body. The channel may be configured to receive the driver, and the fixation element coupler may be configured to temporarily hold a fixation element. The alignment mechanism may extend from the holding sleeve, and may have at least one alignment member configured to engage an underlying structure to which the fixation element is to be affixed so as to align the fixation element and driver assembly with respect to the underlying structure.

An articulating driver having a ball-in-socket joint. The driver may include a driver tip having a spherical head, a retention cap having a domed surface to mate with the spherical head, an input shaft, a spring disposed in an end of the input shaft and in a recess of the retention cap opposite that of the domed surface, and a housing that receives the input shaft, the spring, the retention cap and the spherical head. The housing may have a tapered end to positionally retain the spherical head therein. In another aspect, the driver may include a driver tip coupled to the input shaft that includes an interface to engage a screw. A bushing may engage the driver tip at one end and receive the screw at the other end to retain the screw within the driver.

Provided are fixation members useful in fixing an implant to a bone. The fixation members include an awl tip so as to enable their secure installation by use of an awling motion, which in turn speeds the installation of the fixation members.
摘要:
Arcuate fixation members with varying configurations and/or features are provided, along with additional components for use therewith in provided fixation systems and intervertebral implant systems. The arcuate fixation members may be of varying lengths, cross sectional geometries, and/or cross sectional areas, and may be configured with various features such as heads configured to accept other fixation system components, tabs to allow arcuate fixation member-in-arcuate fixation member or fixation anchor-in-arcuate fixation member configurations. Applications of fixation systems and intervertebral implants systems utilizing arcuate fixation members are particularly suitable when a linear line-of-approach for delivering fixation members is undesirable.
