Problems solved by technology
Open surgical techniques are less than ideal because they typically require large incisions and substantial tissue displacement to access the surgical target site, which is associated with substantial pain, prolonged hospital stays (increasing healthcare costs), and high morbidity in the patient population Rate

Embodiment Construction
[0028] Hereinafter, exemplary embodiments of the present invention are described. In the interest of clarity, not all features of an actual implementation are described in this specification. It should of course be understood that in the development of any such actual implementation, numerous implementation-specific decisions must be made to achieve the developer's specific goals (such as compatibility with system-related and business-related constraints) which will vary from implementation to implementation. . In addition, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure. Furthermore, it will be readily appreciated that, although discussed below primarily within the context of spinal surgery, the surgical access system of the present invention may be employed in any number of anatomical settings to enable acc...

A tissue retraction system comprising a drive gear coupled to a shaft. The tissue retraction system includes a first plurality of linking members located along a second axis and configured to rotate along the second axis based on contact with the drive gear as the drive gear is rotated. The tissue retraction system includes a linking member selector configured to rotate along the first axis, wherein the linking member selector comprises a cylindrical body integrally formed with a handle. The tissue retraction system includes a right arm assembly, a left arm assembly, and a center arm that are each configured to move along trajectories. The tissue retraction system includes a first retractor blade, a second rector blade, and a third retractor blade. The tissue retraction system includes an array with tracking markers.
Description
technical field [0001] The present disclosure describes tissue retraction systems for use during surgical procedures. Background technique [0002] A noteworthy trend in the medical world is the shift away from performing surgery via traditional "open" techniques in favor of minimally invasive or minimally invasive techniques. Open surgical techniques are less than ideal because they typically require large incisions and substantial tissue displacement to access the surgical target site, which is associated with substantial pain, prolonged hospital stays (increasing healthcare costs), and high morbidity in the patient population Rate. Minimally invasive surgical techniques, including so-called "mini-incision" and "minimally invasive" techniques, are gaining favor because they allow access to surgical target sites through significantly smaller sized incisions with greatly reduced tissue displacement requirements. [0003] Currently available access systems require multiple ...
