Embodiment Construction

[0055] Exemplary embodiments of the present invention are described below. In the interest of clarity, not all structures of an actual implementation are described in this specification. It should obviously be understood when developing any such practical implementation that a number of implementation-specific decisions must be made to achieve the developer's specific goals, such as compliance with system-related and business-related constraints, which will vary from implementation to implementation. Moreover, it should be understood that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking for one of ordinary skill in the art having the benefit of this disclosure. In addition, it should be understood that although the following discussion is primarily within the context of spinal surgery, the surgical access system of the present invention may also be employed in any number of anatomical settings to provide access to a...

Abstract

A surgical access system comprising a tissue dilation assembly and a tissue retraction assembly, both of which may be equipped with one or more electrodes for use in detecting the existence of (and optionally the distance and/or direction to) neural structures. A retractor assembly for creating an operative corridor to a spinal surgical target site is disclosed, comprising: a retractor body and a plurality retractor blades extending generally perpendicularly to the retractor body, the retractor body being operable to separate the at plurality of retractor blades relative to each; and a supplemental retractor blade assembly attachable to at least two of the plurality of retractor blades, the supplemental retractor blade assembly comprising an elongated supplemental retractor blade and a crossbar connector, the crossbar connector configured to be attached to said at least two retractor blades while engaging the supplemental retractor blade.

Description

[0001] Related patent application cross-reference [0002] This International (PCT) patent application claims U.S. Provisional Application Serial No. 61 / 376,163 filed August 23, 2010, U.S. Provisional Application Serial No. 61 / 390,248 filed October 6, 2010, and Priority to US Provisional Application Serial No. 61 / 473,138 filed on the 22nd, the complete disclosure of each application is hereby incorporated by reference into this application as if fully set forth herein. technical field [0003] The present disclosure relates to surgical retraction systems and related instruments and methods for accessing a surgical target site to perform a surgical procedure. Background technique [0004] A noteworthy trend in the medical community is the gradual move away from performing surgical procedures using traditional "open" techniques and towards minimally invasive or minimally approached techniques. Open surgical techniques typically require large incisions and substantial tissue d...
