  • Patent number: 5829662
    Abstract: A surgical stapler is provided which is insertable through an endoscopic tube to enable a surgeon to staple a hernia patch to tissue inside a body cavity. The endoscopic surgical stapler includes a staple cartridge pivotally mounted on the distal end of a support tube extending from a handle provided with an actuator mechanism for actuating a staple forming mechanism inside the staple cartridge to fasten staples to the tissue. The staple cartridge is adjustable to different angular orientations relative to the support tube. The staple actuator mechanism is operable to actuate the staple cartridge in any of the angular orientations. The support shaft is rotatable about its longitudinal axis relative to the handle to adjust the rotational orientation of the support shaft and the staple cartridge. The staple cartridge is rotatable about its longitudinal axis relative to the support shaft to adjust the rotational position of the staple cartridge relative to the support shaft.

  • Patent number: 5662662
    Abstract: Various mechanisms, and a method of operating them, are provided for use in a surgical instrument. A shaft and an engaged lost motion operating knob are provided for rotation relative to a handle portion. A latch system prevents rotation of the shaft unless the shaft is rotated by means of the knob. A cartridge is provided for rotation at the distal end of the shaft. Engaging structures are provided for preventing rotation of the cartridge relative to the shaft when axial forces are applied to the cartridge. A loading tool is provided for engaging the cartridge to install the cartridge on the instrument. The cartridge includes a washer for engaging a carrier on which the cartridge is mounted so as to prevent rotation of the washer. The washer is adapted to engage a fastener advancing member in a first angular orientation and is disengaged when the cartridge is rotated to establish a second relative angular orientation.
