摘要： A surgical instrument positioning system, comprising: at least one support (20); a cross member (12) having at least one curved end portion (14), the at least one curved end portion (14) being held by the at least one support (20) such that the cross member (12) is rotatable about an axis (A) extending through a center of curvature of the at least one curved end portion (14) of the cross member (12); and at least one surgical instrument holder (40) suspended from the cross member (12). A laser alignment system for an image intensifier, comprising: at least one laser source (300) which emits planar laser beams in a first and second intersecting planes.

摘要： The present invention involves systems (20) and related methods for performing percutaneous pedicle integrity assessments involving the use of neurophysiology. The fundamental method steps for performing the percutaneous pedicle integrity assessments include (a) percutaneously introducing an insulation member to a pedicle target site; (b) establishing electrical communication between a stimulation element and an interior of a pedicle screw pilot hole; (c) applying a stimulation signal to the stimulation element; and (d) monitoring to assess whether nerves adjacent the pedicle are innervating as a result of the step of applying the stimulation signal to the stimulation element.

摘要： The present invention involves systems and related methods for performing surgical procedures and assessments, including the use of neurophysiology-based monitoring to: (a) determine nerve proximity and nerve direction to surgical instruments employed in accessing a surgical target site; (b) assess the pathology (health or status) of a nerve or nerve root before, during, or after a surgical procedure; and/or (c) assess pedicle integrity before, during or after pedicle screw placement, all in an automated, easy to use, and easy to interpret fashion so as to provide a surgeon-driven system.
