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.
