Benefits of technology

[0012] One feature of various embodiments of the present invention is to provide an articulation joint that enables the proximal and distal tube segments to be coaxially aligned for insertion through a passageway in a trocar and then articulated relative to each other after the joint has passed through the trocar. Accordingly, various embodiments of the i

Problems solved by technology

Approaches to articulating a surgical stapling and severing instrument tend to be complicated by integrating control of the articulation along with the control of closing the end effector to clamp tissue and fire the end effector (i.e., stapling and severing) within the small diameter constraints of an endoscopic instrument.
Due to the

Embodiment Construction

[0034] Turning to the Figures, wherein like numerals denote like components throughout the several views, FIGS. 1 and 2 depict one embodiment of a surgical instrument 10 that is capable of practicing the unique benefits of the present invention. As can be seen in FIGS. 1 and 2, the instrument 10 includes a handle assembly 200 and a surgical implement portion 12. As used herein, the term “surgical implement” refers to a component or set of components configured to engage tissue to accomplish a surgical task. Examples of surgical implements include, but are not limited to: endocutters, graspers, clamps, cutters, staplers, clip appliers, probes or access devices, drug / gene therapy delivery devices, energy devices such as ultrasound, RF, or laser devices, etc.

[0035] In the non-limiting embodiment depicted in the Figures, the surgical instrument 10 includes a hydraulically actuated end effector 22 and handle arrangement 200 of the type disclosed in the U.S. patent application Ser. No. _...

Abstract

Articulation joints for use in connection with a surgical instrument that has a portion that must be passed through a trocar or similar structure and then articulated relative to another portion of the instrument received within the trocar. Various embodiments of the articulation joint include at least one fluid-actuated cylinder or flexible driven member to articulate the surgical implement relative to the handle assembly of the instrument.

Description

FIELD OF THE INVENTION [0001] The present invention relates in general to surgical instruments that are suitable for endoscopically inserting an end effector (e.g., endocutter, grasper, cutter, staplers clip applier, access device, drug / gene therapy delivery device, an energy device using ultrasound, RF, laser, etc.) and, more particularly, to endocutters with articulating end effectors. BACKGROUND OF THE INVENTION [0002] Endoscopic surgical instruments are often preferred over traditional open surgical devices since a smaller incision tends to reduce the post-operative recovery time and complications. Generally, these endoscopic surgical instruments include an “end effector”, a handle assembly and a long shaft that extends between the end effector and the handle assembly. The end effector is the portion of the instrument configured to engage the tissue in various ways to achieve a desired diagnostic or therapeutic effect (e.g., endocutter, grasper, cutter, staplers, clip applier, a...
