Articulating endoscopic surgical apparatus
First Claim
1. An endoscopic surgical apparatus comprising:
- a handle portion;
an endoscopic portion including an elongated tubular section defining a longitudinal axis and having opposed proximal and distal ends, the proximal end of said tubular section extending from said handle portion, and an articulating section pivotally connected to said tubular section adjacent the distal end thereof;
tool means depending from said articulating section of said endoscopic portion for performing a surgical task;
a linkage mechanism including at least one reciprocating member associated with said handle portion and said endoscopic portion for pivoting said articulating section to an articulated position at an angle to the longitudinal axis of said tubular section; and
means for actuating said tool means at least when said articulating section is disposed at an angle to said longitudinal axis of said tubular section.

Abstract
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 90° sector of rotation. In addition, the instrument includes means for rotating the endoscopic portion about its longitudinal axis.

16. A surgical apparatus comprising:
-
a handle portion including at least one pivoting handle; an endoscopic portion including an elongated tubular section defining a longitudinal axis and having opposed proximal and distal ends, the proximal end of said tubular section extending from said handle portion, and an articulating section pivotally connected to said tubular section adjacent the distal end thereof; a pair of cooperating jaws depending from said articulating section of said endoscopic portion; a linkage mechanism associated with said handle portion and said endoscopic portion for pivoting said articulating section to an articulated position at an angle to the longitudinal axis of said tubular section; rotation means for rotating said cooperating jaws about the longitudinal axis of said endoscopic portion relative to said handle portion; and means for operatively connecting said cooperating jaws and said at least one pivoting handle, whereby movement of said at least one pivoting handle will cause said cooperating jaws to open and close. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
