Apparatus and method of performing percutaneous laser spinal disc decompression with the patient retaining consciousness. The clear plastic hub of a discectomy needle has a translucent hub with a chamber which is filled with a saline solution prior to insertion of an optical fiber of a laser apparatus through the needle. Gas production from the vaporization of the nucleus of the disc by the optical fiber of the laser apparatus forms bubbles in the water or saline fluid interface thereby providing the physician with an indication of the rate of vaporization of the disc nucleus. In addition, the detection of gas bubbles in an awake, responsive patent facilitates (a) determining the appropriate amount of laser energy required, (b) confirmation of disc vaporization, (c) following the course of laser surgery, and (d) minimizing the potential for laser associated patient injury. |
