Abstract: A method of and apparatus for performing endoscopic or laparoscopic surgery on a patient's spine is provided. The apparatus includes a trochar which is specifically design for spinal applications. The trochar includes of a first transparent tubular member of a predetermined diameter and a second transparent tubular member of a slightly larger diameter than the first transparent tubular member. The first transparent tubular member fits slidingly within the second transparent tubular member in a telescoping manner. The first transparent tubular member has two ends: an end for remaining in side-to-side contact with said second tubular member and a free end which has an attached metal fitting with serrated teeth for anchoring in the patient's vertebrae when the trochar is inserted through a incision made in the patient's abdomen or chest. The trochar also includes a collar and set screw arrangement. The collar is made up of a short tubular portion having a flanged end.
