Articulation joint for apparatus for endoscopic procedures

摘要

ARTICULATION JOINT FOR APPARATUS FOR ENDOSCOPIC An endoscopic surgical device (100) is provided and includes an endoscopic anchor retaining/advancing assembly (130) including a proximal tube portion (130a) and a distal tube portion (130b) pivotably connected to one another at an articulation joint (150); a proximal inner shaft (138a) rotatably disposed within the proximal tube portion (130a); a distal inner shaft (138b) rotatably disposed within the distal tube portion (130b); and a relatively flexible intermediate drive cable (138c) mechanically interconnecting the proximal inner shaft (138a) and the distal inner shaft (138b), wherein the intermediate drive cable (138c) extends across the articulation joint (150), wherein the intermediate drive cable (138c) defines a central longitudinal axis ("Xl") that is off-set a radial distance ("r") from a central longitudinal axis ("X") of the proximal tube portion (130a) and the distal tube portion (130b).
