    摘要： An arthroscopic or other surgical cutter has features which facilitate fabrication by ceramic molding. The arthroscopic cutter includes a cutter body having a longitudinal axis and a window, an interior channel, and a plurality of cutting edges extending radially outwardly from an outer surface thereof. The features include non-helical, longitudinally aligned cutting edges, controlled thicknesses of the cutting edges, controlled heights of the cutting edges, controlled areas of the windows, controlled diameters of the internal channels, controlled rake angles of the cutting edges, and other parameters.

    摘要： A resecting probe includes a shaft assembly having an outer sleeve and an inner sleeve. The outer sleeve has an axial bore and an outer window in a distal side thereof, and the inner sleeve has an axial extraction channel and inner window in a distal side thereof. The inner sleeve is rotationally disposed in the axial bore of the outer sleeve to allow the inner sleeve window to be rotated in and out of alignment with the outer sleeve window, and the shaft assembly forms a flow aperture in a distal portion when the inner cutting window and the outer cutting window are out of alignment. An electrode is carried on the inner sleeve, and a motor drive is coupled to rotate the inner sleeve relative to the outer sleeve. A controller is coupled to the motor drive and controls rotation of the inner sleeve and can stop rotation of the inner sleeve in a stop position where the outer and inner windows are out of alignment, providing the flow aperture to allow cooling of fluid in a working space and cooling of the probe handpiece during use.

    摘要： A medical device includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A cutting member having sharp edges formed from a wear-resistant ceramic material is carried at the distal end of the elongated sleeve. A motor drive is coupled to the proximal end of the elongated sleeve to rotate the sleeve at cutting member at high speed to cut bone and other hard tissue. An electrode is carried in a surface portion of ceramic cutting member for cautery or radiofrequency ablation of tissue when the sleeve and cutting member are is a stationary position.

    摘要： A medical device includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A cutting member extends distally from the distal end of the elongated sleeve and has sharp cutting edges. The cutting head is formed from a wear-resistant ceramic material, and a motor coupled to the proximal end of elongated sleeve rotate the cutting member. The cutter is engaged against bone and rotated to cut bone tissue without leaving any foreign particles in the site.

    摘要： An arthroscopic system includes a re-useable, sterilizable handle integrated with a single umbilical cable or conduit. The single umbilical cable or conduit carries electrical power from a power and/or control console to the handle for operating both a motor drive unit within the handle and delivering the RF power to a disposable RF probe or cutter which may be detachably connected to the handle. The RF power delivered to the handle and on to the probe or cutter is typically bi-polar, where the handle includes first and second electrical bi-polar contacts that couple to corresponding bi-polar electrical contacts on a hub of the disposable RF probe or cutter is connected to the handle.
