Abstract
A surgical access system including a tissue distraction assembly and a tissue refraction 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 before, during, and after the establishment of an operative corridor to a surgical target site.
Claims9
A system for accessing a surgical target site, comprising:
- a retractor assembly having a plurality of blades releasably coupled to a handle assembly, said plurality of blades capable of being advanced simultaneously to said surgical target site while in a closed position and thereafter selectively opened to create a customized operative corridor to said surgical target site;
- a stimulation electrode coupled to the retractor assembly;
- a patient module;
- a cable electrically coupling the stimulation electrode with the patient module;
- a sensor harness coupled to the patient module;
- and
- a control unit in communication with the patient module and having a touch screen display, wherein the system is configured to:
- send electrical stimulation signals via the stimulation electrode;
- sense a response to the electrical stimulation with the sensor harness;
- assess the response to the electrical stimulation;
- and
- provide, at the touch screen display, a user interface based on the assessed response.
