Abstract: A surgical instrument includes a shaft, a force transmission mechanism disposed at a first end of the shaft, an end effector disposed at a second end of the shaft, an actuation element that extends along the shaft from the force transmission mechanism to the end effector, and an actuation element guide extending along the shaft. The actuation element guide defines a lumen in which the actuation element guide is received. The actuation element guide is compressed into a pre-compressed state along at least a portion of an axial length of the shaft. The actuation element guide can be compressed between first and second blocks of the instrument. The instrument can include a flush tube configured to receive a cleaning fluid, with the actuation element guide being in flow communication with the flush tube to receive the cleaning fluid in the lumen of the actuation element guide.

Abstract: A force transmission mechanism for a teleoperated surgical instrument includes a drive pulley, a drive cable operably coupled with the drive pulley, a driven pulley operably coupled with the drive cable, and an actuation member operably coupled to the driven pulley. The actuation member is configured to transmit force to actuate an end effector of the surgical instrument. Rotational motion of the driven pulley causes translational movement of the actuation element to actuate the end effector. Methods relate to operating a force transmission mechanism.

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.
