Abstract

See full text

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.
