摘要： An end effector includes a first jaw and a second jaw, the first jaw movable relative to the second jaw to transition the end effector between an open configuration and an approximated configuration to clamp tissue therebetween. The end effector may also include a camming assembly movable along a curved path. The camming assembly includes a first camming member which includes a first distal camming portion, a first proximal camming portion, and a first flexible portion extending between the first distal camming portion and the first proximal camming portion. The camming assembly includes a second camming member and a connector at least partially disposed between the first camming member and the second camming member, wherein the camming assembly is movable relative to the end effector to exert a camming force against the first jaw and the second jaw to transition the end effector to the approximated configuration.

摘要： 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.
