    摘要： A valve assembly is provided for permitting the introduction of a surgical instrument into a patient's body while providing a substantial seal about the instrument. The valve assembly includes a sealing gasket assembly providing a fluid tight seal before instrument insertion, and is configured and dimensioned for accommodating an instrument and providing a substantial fluid tight seal after insertion of an instrument. The valve assembly may further include a deformable sealing member having a substantially central aperture for accommodating the instrument. The sealing member provides a substantial seal about the instrument when the instrument is passed therethrough impeding the egress of fluids and gasses through the valve assembly.

    摘要： An apparatus is disclosed for automatically locking an obturator housing to a cannula housing of a trocar assembly when the obturator is advanced to a predetermined distal position. Two latch devices are mounted for pivotal movement within the obturator housing with each having at least one latch positioned at one end thereof. The pivoting latch devices are automatically pivoted into locked engagement with partial apertures or indentations in the cannula housing such that the obturator housing is secured to the cannula housing. Biasing springs are provided to automatically pivot the pivoting latch devices out of engagement with the cannula housing when the obturator is withdrawn to its proximal position.

    摘要： A flexible medical instrument includes an elongate shaft, a jaw tip on the distal end of the elongate shaft and a handle on the proximal end. The elongate shaft includes a coil tube having a distal end fixedly attached to a portion of the jaw tip and a proximal end fixedly attached to a rigid structure at the proximal end of the instrument. The coil tube is disposed within an outer sheath that includes a tubular braid. The elongate shaft and jaw tip are axially rotatable relative to the handle for rotational positioning of the jaws. An actuation element is longitudinally moveable within the shaft to open and close the jaws. The sheath prevents or restricts expansion of the coil tube during pushing of the actuation element.
