Abstract: A device useful for ligating an anatomical structure, e.g., a uterine artery, includes a crochet hook-like shaft, and tubular filament holder, and a housing that includes a thumb-slide attached to the shaft. After inserting the filament holder into tissue adjacent to the artery, the shaft is inserted to a point next to the holder, and a hook on the end of the shaft is used to snare the filament and pull it around the artery. The filament can then be tied down, ligating the artery.

Abstract: A resectoscope for internal surgery generally comprising an operating handle having extendible instruments such as a cutting tool, viewing means such as a telescope and a light conduit and passageways to supply and remove aspirating fluid to lubricate and to wash the surgical site wherein said extendible instruments are contained within a tube divided in cross section by longitudinal wall into first and second sectors, said first sector being smaller than the second sector and containing the viewing means and providing a passageway for the supply of as pirating fluid, said second sector containing the cutting tool and providing a large passageway for the removal of aspirating fluid and surgical morsels for collection and optionally having a valving mechanism activated by retraction or extension of the cutting tool.
