ARTICULATION JOINT FEATURES FOR ARTICULATING SURGICAL DEVICE

摘要

An electrosurgical device comprises a body, an end effector, a cutting member, and a shaft. The end effector includes a pair of jaws that are operable to deliver RF energy to tissue that is clamped between the jaws. The cutting member is operable to sever tissue that is clamped between the jaws. The shaft extends between the body and the end effector. The shaft includes an articulation section that is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft. Some versions include a rotation section that is distal to the articulation section. The rotation section is operable to rotate the end effector relative to the articulation section.

主权项

1. An electrosurgical device, comprising:
(a) a body; (b) an end effector comprising:
(i) a first jaw, wherein the first jaw includes a first electrode, and(ii) a second jaw, wherein the second jaw includes a second electrode,wherein the first jaw is movable toward the second jaw to clamp tissue between the first and second jaws,wherein the first and second electrodes are operable to deliver RF energy to tissue clamped between the first and second jaws; (c) a cutting member operable to cut tissue clamped between the first jaw and the second jaw; and (d) a shaft extending between the body and the end effector, wherein the shaft defines a longitudinal axis, wherein the shaft includes an articulation section, wherein the articulation section is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft.
