Abstract
A drive assembly of an instrument includes an input drive interface removably engageable with an external actuator device and configured to receive drive actuation force from the external actuator device in a state of engagement with the external actuator device, a drive shaft configured to be driven in rotation, a capstan, and a splined snap-fit connection mechanism between the drive shaft and the capstan. The splined snap-fit connection mechanism includes splined engagement features configured to engage each other so as to prevent relative rotation between the drive shaft and the capstan, and a plurality of snap-fit elements to provide a snap-fit engagement between the drive shaft and the capstan so as to provide resistance to relative axial movement between the drive shaft and the capstan.
