Embodiment Construction

[0141] Referring to the drawings, wherein like reference numerals represent like parts throughout, figure 1 A surgical instrument capable of realizing the unique advantages of the present invention is shown, wherein the instrument shown schematically refers more particularly to a surgical stapling and cutting instrument 10 . In particular, the size of the surgical stapling and cutting instrument 10 is as figure 1 The illustrated non-articulated condition can be passed through the cannula channel of the trocar to a surgical site (not shown) in the patient for performing the surgical procedure. An end effector, shown in the schematic version as staple applying assembly 20 , is connected distally to shaft portion 16 by articulation joint 100 . After the staple applying assembly 20 is inserted through the cannula channel of the trocar, external force is applied to the staple applying assembly 20 by "passively" contacting the staple applying assembly 20 with an organ or other body...

Abstract

The present invention relates to a surgical stapling and cutting instrument with articulatable end effector. Various types of passive articulation joints are disclosed for interconnecting a proximal frame portion to the end effector to facilitate pivotal travel of the end effector relative to the proximal frame portion of the instrument.

Description

technical field [0001] The present invention relates generally to endoscopic surgical instruments, including but not limited to surgical stapling instruments capable of applying rows of staples to tissue while cutting the tissue between the rows of staples, and more particularly to Improvements related to articulation joints for use with articulating end effectors for surgical stapling instruments. Background technique [0002] Endoscopic surgical instruments are often preferred over traditional open surgical instruments because smaller incisions tend to reduce postoperative recovery time and complications. Accordingly, there has been significant development in the field of endoscopic instruments adapted for precise placement of a distal end effector through the cannula of a trocar at the site of the desired surgical procedure. These distal effectors (e.g., endoscopic cutters, graspers, cutters, staplers, clip appliers, access devices, drug / gene therapy delivery devices, an...
