Abstract
A surgical instrument has an end effector disposed on an elongate shaft end, the shaft projecting from a handle. The end effector grasps, cuts, and seals and/or coagulates tissue, and one of the operations is controlled by a rotatable drive shaft contained within the elongate shaft. The drive shaft moves longitudinally within the elongate shaft to move the end effector between a first and second condition. The instrument may have a further component such as a cutting blade arranged to move longitudinally within the drive shaft. The drive shaft is provided with apertures so as to reduce the surface area of the drive shaft and hence the friction between either the drive shaft and the elongate shaft and/or the drive shaft and the cutting blade, whilst at the same time providing channels through the drive shaft through which fluid can drain.
