Heat management configurations for controlling heat dissipation from electrosurgical instruments
First Claim
1. A surgical instrument, comprising:
- an end effector comprising;
a first jaw comprising an electrode having a distal end;
a second jaw, wherein the first jaw and the second jaw are operably coupled together; and
a cutting member configured to translate between a retracted position and a fully advanced position with respect to the first jaw, wherein the cutting member comprises a cutting surface and a body, wherein the body defines a cavity and at least one opening communicating with the cavity, and wherein the at least one cutting member opening is proximal to the distal end of the electrode when the cutting member is in the fully advanced position.

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 at least one energy delivery surface and heat dissipation means for dissipating heat from at least a portion of the end effector. For example, in at least one embodiment, the end effector may comprise a first jaw, a second jaw, and a cutting member. The cutting member may comprise a cutting surface and a body, which may define a cavity and at least one opening communicating with the cavity. A fluid may be moved through the cavity to and/or from the opening(s). Additionally, in at least one embodiment, a surgical instrument'"'"'s end effector may comprise a first jaw, a second jaw, a cutting member, and at least one heat pipe. Various other heat dissipation means are also disclosed.
