    摘要： The present invention includes a surgical stapler having a curved end-effector which is configured to deploy staples in at least one curved staple line. In various embodiments, the surgical stapler includes a staple cartridge, an anvil, and a cutting member having a cutting surface wherein the cutting member is relatively movable with respect to the anvil and the staple cartridge. In one embodiment, the staple cartridge can be configured to deploy staples along different, non-parallel axes. As a result, the staples can be deployed in a significantly curved staple line. In various embodiments, the surgical stapler includes a flexible driver operably engaged with the cutting member to move the cutting member relative to the anvil and the staple cartridge. In these embodiments, the driver can include an elongate cross-section defined by a width and a height wherein its width is greater, and in some cases, substantially greater, than its height.

    摘要： A surgical stapler for applying staples to compressed tissue comprising: a handle portion having surfaces adapted to be manually grasped by a surgeon; a cartridge retention portion and an anvil retention portion, means for mounting said cartridge retention portion and said anvil retention portion for relative movement between a closed position in which said cartridge retention portion and said anvil retention portion are in closely spaced relationship for clamping tissue to be stapled therebetween and an open position in which said cartridge retention portion and said anvil retention portion are spaced farther from each other than in the closed position, an anvil having a plurality of specially shaped surfaces, said cartridge retention portion having a staple housing for enclosing six rows of staples in substantially parallel, linear rows having proximal and distal ends, said six rows being spaced laterally across the staple housing such that any line drawn laterally across the staple line crosses at least three staples, staple drivers adjacent staples, and a plurality of pushers each having camming surfaces, said staple housing being elongate to define a longitudinal axis, said staple housing having a plurality of longitudinally extending pusher slots adapted to receive said pushers to afford movement of said pushers in a firing direction between pre-fired and fired positions, and a plurality of driver channels for receiving said staple drivers to afford movement of said staple drivers in a staple driving direction between pre-eject and ejected positions; and each of said staple drivers having a cam follower surface for engaging the camming surface of a pusher to move the staple driver from the pre-eject toward the ejected position to substantially sequentially eject the staples in a row from the staple housing and press the ejected staples against the specially shaped surfaces of the anvil to engage, form and close staples in tissue clamped between the staple housing and the anvil.

    摘要： Query electrodes are provided for monitoring the electrical impedance of tissue as it is treated with electrosurgical energy. In one embodiment, based on a predicted model of tissue impedance and a number of initial impedance readings, the impedance at which tissue treatment is completed is predicted. More particularly, a minimum impedance level is measured and a function of the minimum impedance is used to determine impedance at which coagulation is completed. A control device is provided for bringing the output of the generator within an optimum range based on a system load curve. In one embodiment the impedance monitoring device is used in conjunction with a bipolar electrosurgicalinstrument. Preferably, the instrument comprises electrically opposite therapeutic electrodes, each located on one or more tissue engaging surfaces for engaging tissue to be treated, and electrically opposite query electrodes, located on one or more tissue engaging surfaces. The therapeutic electrodes provide therapeutic energy to the tissue while the query electrodes provide a lower voltage electrical sensing energy for the purpose of measuring tissue impedance at various stages, e.g. before, during, or after tissue treatment.

    摘要： A staple cartridge (26) for a surgical stapler (20) includes a staple drive member (202) which is driven by longitudinal movement of a cam (78) through the surgical stapler for firing at least one surgical staple (66). The staple drive member (202) comprises a staple drive element (212) having a staple driving surface (64) in association with the surgical staple (66) for angular orientation of the surgical staple, when applied, with respect to the direction of movement of the cam. The staple drive member (202) further comprises a cam contact element (232) having a cam contact surface (216) for being engaged by the cam (78), and an arrangement (220,222) for pivotally connecting the staple drive element to the cam contact element.
