Abstract: A surgical instrument may include a shaft, a force transmission mechanism, and an end effector. The shaft may have a proximal end and a distal end. The force transmission mechanism may be coupled to the proximal end of the shaft. The end effector may be coupled to the distal end of the shaft. The shaft may include a body having an outer surface and an inner surface. The inner surface may surround a lumen configured to receive a drive member that extends through the lumen. The outer surface of the body may form an outer surface of the shaft. The body may be made of a single material from the inner surface of the body to the outer surface of the body.

Abstract: A surgical instrument including a shaft, an end effector, and a push/pull drive element is provided. The push/pull drive element may include a head extending perpendicular to a push/pull direction of the push/pull element. The head of the push/pull drive element may have end portions each having a cross-section that differs from a cross-section of a main portion of the head between the end portions. The push/pull drive element may include an engagement portion in contact with the end effector to actuate the end effector. The engagement portion may have a first width and an end portion may have a second width, with the second width being greater than the first width. A surgical instrument is also provided that may include an electrical connector connecting at least one conduit providing electrical energy to the end effector. The end effector may be in sliding contact with a portion of the connector.
