  • Surgical instrument with improved handle assembly
    Patent number: 7731725
    Abstract: A modular clip applier includes a cartridge containing multiple surgical clips, and a handle assembly for operating the cartridge to crimp one of the clips onto body tissue of a patient. The handle assembly has a scissors configuration with a bayonet coupling, and flange pairs widely separated to provide a high degree of stability. The bayonet coupling enables the handles of the assembly to be fully separated for cleaning. Snap fittings between the cartridge and handle assembly are provided at the fulcrum and also at a spaced location where an operating pin of the cartridge engages intersecting slots in the flanges. Overdrive protection of three different types is contemplated along with a structure facilitating operation of the handle assembly by palming a pair of handle bars.
