Patent Images
1. A surgical apparatus comprising:
- an articulation gear;
a plurality of distinct cam paths each defined as a recess in said articulation gear;
at least one holder post extending into each cam path; and
a handle including at least one button,wherein at least part of said articulation gear is held within said handle,wherein said at least one button includes a holder post deflection cam defined thereon,wherein each holder post and corresponding cam path are movable relative to one another, each holder post remaining within said corresponding cam path during such relative motion, andwherein distal motion of said at least one button causes said holder post deflection cam on said at least one button to move linearly in the distal direction to engage at least one of the holder posts.
