Apparatus for performing a discectomy through a trans-sacral axial bore within the vertebrae of the spine

Methods and apparatus for and performing a partial or complete discectomy of an intervertebral spinal disc accessed by one or more trans-sacral axial spinal instrumentation/fusion (TASIF) axial bore formed through vertebral bodies in general alignment with a visualized, trans-sacral anterior or posterior axial instrumentation/fusion line (AAIFL or PAIFL) line. A discectomy instrument is introduced through the axial bore, the axial disc opening, and into the nucleus to locate a discectomy instrument cutting head at the distal end of the discectomy instrument shaft within the nucleus. The cutting head is operated by operating means coupled to the instrument body proximal end for extending the cutting head laterally away from the disc opening within the nucleus of the intervertebral spinal disc and for operating the cutting head to form a disc cavity within the annulus extending laterally and away from the disc opening or a disc space wherein the disc cavity extends through at least a portion of the annulus. A discectomy sheath that is first introduced to extend from the skin incision through the axial bore and into the axial disc opening having a discectomy sheath lumen that the discectomy instrument is introduced through. The discectomy sheath is preferably employed for irrigation and aspiration of the disc cavity or just aspiration if irrigation fluids are introduced through a discectomy instrument shaft lumen. The cutting head of the discectomy tool is deflected from the sheath lumen laterally and radially toward the annulus using a deflecting catheter or pull wire.

Noninvasive measurement of chemical substances

Utilization of a contact device placed on the eye in order to detect physical and chemical parameters of the body as well as the non-invasive delivery of compounds according to these physical and chemical parameters, with signals being transmitted continuously as electromagnetic waves, radio waves, infrared and the like. One of the parameters to be detected includes non-invasive blood analysis utilizing chemical changes and chemical products that are found in the conjunctiva and in the tear film. A transensor mounted in the contact device laying on the cornea or the surface of the eye is capable of evaluating and measuring physical and chemical parameters in the eye including non-invasive blood analysis. The system utilizes eye lid motion and/or closure of the eye lid to activate a microminiature radio frequency sensitive transensor mounted in the contact device. The signal can be communicated by wires or radio telemetered to an externally placed receiver. The signal can then be processed, analyzed and stored. Several parameters can be detected including a complete non-invasive analysis of blood components, measurement of systemic and ocular blood flow, measurement of heart rate and respiratory rate, tracking operations, detection of ovulation, detection of radiation and drug effects, diagnosis of ocular and systemic disorders and the like.
