Staple pocket arrangement for surgical stapler
First Claim
1. A surgical stapler device for closing staples, each staple having a distal staple leg and a proximal staple leg, the device comprising:
- an anvil portion including at least two rows of staple pockets, each one of the at least two rows including a pair of staple pockets corresponding to each staple, each pair of staple pockets including a distal staple pocket for receiving and closing the distal staple leg of the corresponding staple and a proximal staple pocket for receiving and closing the proximal staple leg of the corresponding staple, wherein a staple pocket in a first row of staple pockets is nested with a staple pocket from a second row of staple pockets,wherein each side of each staple pocket of the pair of staple pockets has a series of convex and concave curves when viewed from above, andwherein a distance between a longitudinal centerline of the first row of staple pockets and a longitudinal centerline of the anvil portion is greater than a distance between a longitudinal centerline of the second row of staple pockets and the longitudinal centerline of the anvil portion, and wherein a distance between the longitudinal centerline of the first row of staple pockets and the longitudinal centerline of the second row of staple pockets is less than a maximum width of each staple pocket.

Abstract
A staple pocket arrangement on the anvil portion of a surgical stapler device includes pairs of staple pockets corresponding to each one of a plurality of staples to be closed. The staple pockets may have a generally triangular shape when viewed from above. Each respective staple leg is received at a longitudinal end of the staple pocket that provides a relatively wide target area for receiving the staple leg to eliminate or at least minimize the likelihood that a staple leg will miss the staple pocket due to, e.g., misalignment between a first jaw of the surgical stapler having the anvil and a second jaw of the surgical stapler having a cartridge configured to fire the staples. The staple pockets may be arranged in rows, each row of staple pockets being longitudinally offset from another row, such that each staple pocket in a first row of staple pockets is nested with a staple pocket from an adjacent row of staple pockets to make more efficient use of space on the anvil.

17. A surgical stapler device for closing at least one staple having a distal staple leg and a proximal staple leg, the device comprising:
-
an anvil portion including a pair of staple pockets corresponding to each staple, the pair of staple pockets including a distal staple pocket for receiving and closing the distal staple leg of the corresponding staple and a proximal staple pocket for receiving and closing the proximal staple leg of the corresponding staple, wherein each staple pocket of the pair of staple pockets has a generally triangular shape when viewed from above, wherein each side of the generally triangular shape of each staple pocket of the pair of staple pockets has a series of convex and concave curves when viewed from above, and wherein a staple pocket in a first row of staple pockets is nested with a staple pocket from a second row of staple pockets, wherein a distance between a longitudinal centerline of the first row of staple pockets and a longitudinal centerline of the anvil portion is greater than a distance between a longitudinal centerline of the second row of staple pockets and the longitudinal centerline of the anvil portion, and wherein a distance between the longitudinal centerline of the first row of staple pockets and the longitudinal centerline of the second row of staple pockets is less than a maximum width of each staple pocket. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. An anvil comprising at least two rows of staple pockets, each one of the at least two rows including a pair of staple pockets, each pair of staple pockets corresponding to a single staple and including a distal staple pocket and a proximal staple pocket, wherein a staple pocket in a first row of staple pockets is nested with a staple pocket from a second row of staple pockets,
wherein each side of each staple pocket of the pair of staple pockets has a series of convex and concave curves when viewed from above, and wherein a distance between a longitudinal centerline of the first row of staple pockets and a longitudinal centerline of the anvil portion is greater than a distance between a longitudinal centerline of the second row of staple pockets and the longitudinal centerline of the anvil portion, and wherein a distance between the longitudinal centerline of the first row of staple pockets and the longitudinal centerline of the second row of staple pockets is less than a maximum width of each staple pocket.
