Electrosurgical instrument with separate closure and cutting members
First Claim
1. A surgical instrument, comprising:
- an end effector comprising;
a first jaw defining a channel;
a second jaw, wherein the first jaw and the second jaw are operably coupled together such that the first jaw may move between an open position and a closed position with respect to the second jaw;
a closure beam sized and configured to fit at least partially within the channel, wherein the closure beam is configured to translate along the channel between a first position and a second position, wherein the first jaw is at the closed position when the closure beam is at the second position; and
a cutting member sized and configured to fit at least partially within the channel, wherein the cutting member is configured to translate along the channel and with respect to the closure beam.

Abstract
In various embodiments, a surgical instrument is provided that may comprise an end effector for performing a surgical procedure on tissue, for example. The end effector may comprise a pair of jaws, a closure beam, and a cutting member. The closure beam and the cutting member may be releasably coupled together by an interlocking member such that movement of the cutting member may cause the closure beam to also move relative to the jaws and cause the jaws to close and grip tissue, for example. The interlocking member may then unlock, allowing the cutting member to move through the gripped tissue and relative to the closure beam. Additionally, the cutting member and closure beam may be operated by a single trigger, which may be configured to provide haptic feedback to a user at various stages. Further, the jaws may be electrically energized to deliver energy and/or seal the gripped tissue.

17. A surgical instrument, comprising:
-
an end effector comprising; a first jaw comprising a tissue contacting surface; a second jaw, wherein the first jaw and the second jaw are operably coupled together such that the first jaw may move between an open position and a closed position with respect to the second jaw; a closure beam operably contacting the first jaw, wherein the closure beam is configured to translate with respect to the first jaw between a first position and a second position, and wherein the first jaw is urged into the closed position by the closure beam when the closure beam is at the second position; a cutting member defining a longitudinal axis, wherein the cutting member is configured to translate with respect to the first jaw between a retracted position and a fully advanced position, and wherein the cutting member is configured to translate with respect to the closure beam; and an interlocking member configured to selectively hold the cutting member and the closure beam together such that the cutting member and the closure beam translate synchronously with each other in at least one direction with respect to the first jaw. - View Dependent Claims (18, 19)
