Abstract

A structured illumination surgical system is disclosed, one embodiment comprising: a light source for providing a light beam; an optical cable, comprising an optical fiber, optically coupled to the light source for receiving and transmitting the light beam; a handpiece, operably coupled to the optical cable; an optical element, a proximal end of the optical element optically coupled to a distal end of the optical fiber, for receiving the light beam and scattering the light beam to illuminate an area (e.g., a surgical site), wherein the surface area of the proximal end of the optical element is greater than the surface area of the distal end of the optical fiber; and a cannula, operably coupled to the handpiece, for housing and directing the optical fiber and the optical element.
