Surgical instrument with curvilinear tissue-contacting surfaces

摘要

A surgical stapling instrument including a handle assembly, an elongated body portion, a shell assembly and an anvil assembly. The elongated body portion extends distally from the handle assembly and defines a longitudinal axis. The shell assembly is disposed adjacent a distal end of the elongated body portion and includes a non-planar, tissue-contacting surface oriented obliquely with respect to the longitudinal axis. The anvil assembly includes a non-planar, tissue-contacting surface oriented obliquely with respect to the longitudinal axis. The tissue-contacting surface of the anvil assembly is configured to align with the tissue-contacting surface of the shell assembly when the anvil assembly and shell assembly are in the approximated position.

1. A surgical instrument, comprising:
a handle assembly; an elongated body portion extending distally from the handle assembly and defining a longitudinal axis; a first jaw member disposed adjacent a distal end of the elongated body portion, the first jaw member including a non-planar tissue-contacting surface; and a second jaw member having a non-planar tissue-contacting surface, and the entirety of, the non-planar tissue-contacting surface of the second jaw member divided into exactly two curvilinear segments, each curvilinear segment including exactly one concave portion and exactly one convex portion, wherein the tissue-contacting surface of the second jaw member is configured to align with the tissue-contacting surface of the first jaw member when the second jaw member and the first jaw member are in an approximated position.
