Abstract
Surgical instruments are disclosed that utilize high-pressure liquid jets to perform a variety of useful functions. In certain embodiments, surgical instruments are described incorporating one or more liquid jets utilized to contact tissue excised by a non-liquid jet tissue-cutting component of the surgical instrument. In certain embodiments, a liquid jet of a surgical instrument can be utilized for the purpose of excising tissue of a patient immobilized and/or manipulated by the surgical instrument. Also described are surgical devices of the type characterized by curettes, rongeurs, bone punches, bone cutting forceps, morcellators, surgical micrograspers, with functionality and performance supplemented by the integration of a liquid jet. Also disclosed are methods of using certain liquid jet-containing surgical instruments for performing surgical procedures, for example surgical procedures on the spinal column of a patient.
