ARTICULATING ENDOSCOPIC SURGICAL APPARATUS

摘要

A surgical instrument is provided for use in endoscopic or laparoscopic surgery. The instrument includes a handle portion and an endoscopic portion. The endoscopic portion has an elongated tubular section having opposed proximal and distal ends, the proximal end of which extends from the handle portion, and an articulating section which is pivotally connected to the tubular section adjacent the distal end thereof. Tool means depend from the articulating section and a linkage mechanism is associated with the endoscopic portion for pivoting the articulating section relative to the longitudinal axis of the tubular section, within a sector of rotation. In addition, the instrument includes means for rotating the endoscopic portion about its longitudinal axis.
