Abstract:
1. A powered apparatus comprising: an elongate pole with a proximal region and a distal region; a drive at the proximal region of the elongate pole and operable to rotate a first component on the drive around a first axis; a tool at the distal region of the elongate pole and comprising a second component that is rotatable around a second axis in a first direction to operate the tool; and a power transmission assembly for transmitting a drive force generated by rotation of the first component to the second component, that is downstream of the first component, to cause rotation of the second component around the second axis and thereby operation of the tool, the power transmission assembly comprising a flexible drive link with a substantially straight flexible length extending along a third axis, the flexible drive link located between the drive and at least one other substantially inflexible drive part that is part of the power transmission assembly and downstream of the flexible drive link, the at least one other substantially inflexible drive part having a length greater than the flexible length of the flexible drive link, the flexible length of the flexible drive link greater than four (4) inches, wherein the flexible drive link comprises at least one coiled member, wherein the at least one other substantially inflexible drive part has an elongate, substantially straight shape and an axis substantially coincident with the third axis, a drive force from the drive transmitted from the first component to and through the flexible drive link and from the flexible drive link to and through the at least one other substantially inflexible drive part to the second component.
