The Yeung Endoscopic Spine System revolves around a specially conﬁgured endoscope designed to maximize visualization in a potential space through the integration of multiple inﬂow and outﬂow ports. The integration of these ports include an adequate size working channel incorporated in a scope strong enough to allow manipulation in the posterolateral portal and foramen yet small enough to adequately access the triangular zone bordered by the superior facet of the inferior vertebra, the end plates of the disc space and the exiting nerve.
