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 and supports 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. The user can lock the tip against rotary motion. The tip assembly is removably attached to the instrument, such as by using a bayonet-type locking element.
