摘要： An expandable access device for providing access to a surgical site in the body. The expandable access device comprises a first blade, a second blade and a connection mechanism operable connecting the first and second blades. Each blade may have a first portion, a second portion and an intermediate portion between the first and second portions. The intermediate portions of each blade may be bent such that the first and second portions of each blade may be at an angle with respect to each other. The connection mechanism may have first and second elongated member, which may be in a criss-cross configuration. A first end of the first and second elongated members may be connected to the first blade and a second end of the first and second elongated members may be connected to the second blade. Such a construction may enable the first and second blades to separate and pivot with respect to each other. An actuating device may be connected to the first and second blades and/or the connecting mechanism and may be used to move the first and second blades with respect to each other.

摘要： A method for performing spinal fixation and instrumentation. A first incision may be made through the skin and a passageway may be created to the spine. A screw may be inserted through the passageway and into a vertebrae. The screw may have a head portion including a channel. An insertion guide may be operable connected to the screw. The insertion guide may have first and second longitudinal slots. Additional screws may each be inserted through separate incisions or through the first incision. Insertion guides may be operably connected to a head portion of each screw. A sleeve may be positioned into one insertion guide in a first position to guide a rod through at least one other insertion guide. The sleeve may be rotated to a second position to allow the rod to move down the slots of the insertion guide(s) and into the head portion of the screw.
