The present invention provides a series of devices for surgical procedures utilizing rotatable components for grinding, cutting, ablating, polishing, drilling, screwing, etc., tissues of the body of a patient. The invention includes, a series of surgical instruments (100) including rotatable shafts (124), and surgical components (122) drivable by the shafts (124) that can be utilized for contact with tissue in a surgical operating field. Some preferred surgical instruments provided by the invention utilize a liquid jet-driven rotor mechanism (454) for driving rotation of the rotatable shaft (124). Some preferred instruments provided by the invention include both a liquid jet-driven rotor mechanism (454) and a nozzle (192) at the distal end of the instrument for forming a liquid cutting jet for cutting or ablating tissue of a patient. Such instruments can include a liquid flow directing valve (180) therein that includes a pressure-tight sealing component (556) comprising a sealing element that is slidably moveable within a cylinder (552) of the valve (180). The invention provides methods for utilizing the surgical instruments in surgical procedures involving both cutting or ablating tissue of a patient with a liquid cutting jet and grinding, cutting, or ablating tissue with a rotating surface of a surgical instrument. |
