<p>ARTICULATING JOINT FOR SURGICAL INSTRUMENTS Abstract A surgical apparatus (100) comprising a handle assembly (110); an elongated body extending from the handle assembly and including a proximal portion, a distal portion, and an articulation joint (130) disposed between the proximal portion and the distal portion. An articulation mechanism (126) is disposed within the elongated body configured to move the distal portion about the articulation joint from a first position in axial alignment with the proximal portion to a second position offset from the proximal portion; and a drive assembly extending through the elongated body. The drive assembly including a first drive shaft (65) extending from the handle assembly to the articulation joint and a second drive shaft extending from the articulation joint to the tool assembly (140). The first drive shaft includes an extension mechanism for maintaining the first drive shaft in engagement with the second drive shaft during articulation of the distal portion of the elongated body about the articulation joint.</p> |
