Abstract: Surgical micro-resecting and evoked potential monitoring system and method. The system includes a micro-resecting instrument, handpiece, and evoked potential monitor. The instrument includes an outer tube forming a cutting window at which a cutting tip of an inner member is located. A hub assembly rotatably maintains the inner and outer members. An electrically non-conductive material covers a region of the outer tube, and wiring is connected to an exposed surface of the outer tube. The instrument defines a probe surface proximate the cutting window as part of an electrical pathway with the wiring. The hub assembly is powered by the handpiece, and the wiring is connected to the evoked potential monitor. Evoked potential monitoring is performed at the probe surface via stimulation energy delivered along the electrical pathway, and tissue/bone resection occurs with rotation of the cutting tip.

Abstract: A guard for use with a surgical cutting system. The guard includes a housing and wiring. The housing defines a longitudinal passageway, and is configured for releasable attachment to an instrument handpiece. The wiring is coupled to the housing and includes an electrically conductive wire and an insulative material. The wire defines opposing, first and second ends, with the first end being positioned within the passageway. The insulative material covers the wire apart from the first end such that the first end of the wire is exposed within the passageway. The first end of the wire establishes an electrical connection with a cutting tool shank upon placement within the passageway.

Abstract: A disposable battery powered rotary tissue cutting instrument for soft tissue removal includes a blade attached to a powered surgical handpiece. The blade comprises an elongate tubular outer member and an inner member rotatably disposed within the outer member to cut anatomical tissue. The handpiece contains a motor having a drive shaft coupled in driving engagement with the inner member and a battery unit for supplying electric current to rotate the drive shaft to effect rotation of the inner member within the outer member. The inner member is continuously rotated in one direction or is continuously oscillatorily rotated in forward and reverse directions. The instrument is disposable after single patient use and may include a use-limiting unit for automatically disabling the instrument to prevent its reuse after completion of a surgical procedure performed using the instrument on a single patient. The blade may be used for electric cautery.
