Abstract
An endoscopic surgical instrument is designed for axial elongation by incorporating a manually operated mechanism which elongates the instrument upon manual rotation. The manually operated mechanism is joined to an internal rod and tube, which are likewise extended and which support a functional element at the tip of the instrument. Operation of the functional element at the distal tip of the instrument is achieved by manipulations at the proximal end of the instrument, and is not impaired by the extension.
