    摘要： A stamped jaw for use in an endoscopic device including a cup having opposite side walls extending longitudinally along the jaw spaced equally from and on opposite sides of a longitudinally extending median plane, and an end wall extending between the side walls. The jaw also includes a hinge extension attached to the cup having a hinge pin opening adapted to receive a hinge pin to pivotally connect the jaw with an identical second jaw, an inner face surrounding the hinge pin opening extending along the median plane, and an outer face positioned to abut a clevis when assembled in the endoscopic device.

    摘要： A surgical instrument including an elongate member having opposite ends, and a clevis attached to one end of the opposite ends. The clevis has a pair of spaced arms. The instrument includes a pin extending between the spaced arms of the clevis, and an end effector having a pivot hole receiving the pin extending between the spaced arms of the clevis for pivotal movement relative to the clevis and a control arm for pivoting the end effector about the pin. The instrument also includes an actuator wire having a helical portion connected to the control arm of the end effector.

    摘要： A surgical stapler having an end effector with a reduced stacking height for its components to decrease the diameter of a trocar cannula or other access device during minimally invasive surgery is disclosed. The end effector includes an elongated channel containing a staple cartridge and an anvil movable toward and away from the channel. The anvil is movable to first, second and third fixed positions relative to the channel. The first fixed position is a closed position which eliminates clearance between the anvil and cartridge. The second fixed position is an open position for inserting tissue between the anvil and cartridge. The third fixed position is a clamped position where a tissue-clamping gap exists between the anvil and cartridge to properly clamp tissue. The elimination of clearance between the anvil and cartridge of the first fixed position of the anvil reduces the stacking height, and therefore enables the user to insert the stapler through a smaller diameter access opening.

    摘要： An electrosurgical instrument is provided for cauterization and/or welding of tissue of varying impedance, thickness and vascularity especially in the performance of endoscopic procedures. The instrument compresses the tissue between one pole of a bipolar energy source located on one interfacing surface, and a second interfacing surface applying pressure in a predetermined range. A second pole is located one of the two interfacing surfaces. In a preferred embodiment, the second pole is located on the same interfacing surface as the first pole and an insulator electrically isolates the two poles. A preferred application of the invention is in a cutting instrument wherein a hemostatic line is formed along a cut line using RF energy.
