US 5,131,382 A · Endoscopic percutaneous discectomy device

Abstract

A system of energy form generating and transmitting devices that allow direct visualization during removal of disc tissue material from the human body discs which are located between vertebrae of the back, during percutaneous discectomy. Energy form generators are controlled and coordinated within a modularized console. Energy form transmitters are placed partially within the disc and are coordinated in the same physical structure to minimize size. A coordinated system of surgical devices which create a space in the disc (21), (71), (172), illuminate the disc space (20), (120), removed disc material (21), (71), (122), under direct visual control from the posterior aspect of the disc (134), (128), and provide a means for transporting debris (22), (23), (172), (166), (78), from the disc during the surgical procedure. A system of energy form generating and energy transmitting surgical devices which function in an integrated manner to provide illumination, visualization, tissue resection, and transport of resected tissue, from an area of the body which not normally a body cavity.
