摘要： 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. Separate actuator mechanisms are provided on the handle to control the pivotal movement of the staple cartridge, the rotation of the support shaft, and the rotation of the staple cartridge relative to the support shaft.

摘要： Trocar assembly devices that include trocar tubes of different diameters to accommodate small and large diameter implements for providing communication into an anatomical cavity and a unique method of utilizing such devices. The trocar assembly devices include an outer or larger diameter trocar tube and an inner or smaller diameter trocar tube. A distal end portion of the inner trocar tube is tapered and extends distally beyond a distal end portion of the outer trocar tube. The tapered end portion is provided with threads formed on an outer surface thereof to facilitate insertion of the device through the skin and into an anatomical cavity

摘要： 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. In the first angular orientation, the fastener advancing member is restrained against longitudinal movement to assist in installation of the cartridge onto the instrument. The distal end of the instrument can be articulated, and a helical gear operator is provided for effecting the articulation. The helical gear pitch decreases in a direction such that the mechanical advantage is increased as the articulation angle increases. A trigger actuating system includes a trigger lever with a cam channel, a pin in the cam channel, and a link connected at one end to the pin and at the other end to a reciprocatable driver. A frame is provided with a guide channel for guiding an end of the pin. The trigger lever is pivotally mounted to the frame and biased to a normally unactuated position.
