    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: The present invention includes a surgical stapler having 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 at least one embodiment, one of the anvil and the staple cartridge defines a slot which is configured to receive at least a portion of the cutting member and guide the cutting member as it is moved relative to the anvil and the staple cartridge. In these embodiments, the slot can define a path having linear and/or curved portions. In various embodiments, the path can include a curved portion having a first portion that extends away from the shaft axis and a second portion that extends toward the axis. In one embodiment, the path can include a curved portion defined by an arc corresponding to an angle greater than 90 degrees.
