Embodiment Construction

[0054] 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

The invention relates to a retractor assembly for forming a surgical access to a spinal surgical target site comprising a retractor body and a plurality of retractor blades extending perpendicular to the retractor body. The retractor body is operable to separate the plurality of retractor blades relative to one another to retract the tissue away from the interior of the retractor blades and retracts the interior of the tissue which is far away from the retractor blades when the retractor blades are separated, thereby forming a surgical access. The retractor assembly also comprises a supplemental retractor blade assembly can be attached to two of the plurality of retractor blades and includes a crossbar connector and an elongated supplemental retractor blade. The crossbar connector extends from a first end to a second end and includes an elongate slot. The elongate slot is open at the first end and is configured to slidably receive elements of the two retractor blades to attach the cross-bar connector in a slidable manner to the two retractor blades. The crossbar connector further includes a back surface configured to engage the supplemental retractor blade.

Description

[0001] The application of the present invention is a divisional application of the application number 201180050236.0 (international application number PCT / US2011 / 001489), the title of the invention is "surgical access system and related methods", and the application date is August 23, 2011. technical field [0002] 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 [0003] 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 displacement to access surgical target sites, are often associated with severe pain, long hospital stays (increasing healthcare costs), and greater morbidity in the patient population, ...
