A placement tip that is bent, angled, or curved and extends distally from one of the jaws of the end effector. The placement tip is elastically deformable when the placement tip is subject to a clamping force, such as when the end effector is closed with the jaws in contact or when tissue is clamped between the jaws of the end effector. When the placement tip deflects, relative angles defined in part by the placement tip vary compared to an initial state without the clamping force. Furthermore, a distal end of the placement tip may change position based on the state of deflection of the placement tip in response to the clamping force. ## Claims ### Claim 1 An apparatus comprising: (a) a first jaw having a plurality of staple apertures that house a plurality of staples; (b) a second jaw having a plurality of staple forming pockets configured to form the staples, wherein the first and second jaws are configured to transition from an open state to a closed state to clamp and staple tissue with the staples; (c) a tip coupled with one of the first and second jaws such that a proximal end of the tip is longitudinally constrained relative to the selected jaw, the tip comprising a body extending from the proximal end to a distal end; and wherein the distal end is moveable, via the application of a force external to the tip, from a first position, where the distal end is positioned at a first angle relative to the one of the first and second jaws, to a second position where the distal end is positioned at and a second angle, different from the first angle, relative to the one of the first and second jaws, wherein when the first and second jaws are in the closed state without tissue present between the first and second jaws and the distal end is in the first position, the distal end contacts the other of the first and second jaws. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the distal end is moveable about a range of angles relative to the one of the first and second jaws, including the first and second angles. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the external force is applied by the other of the first and second jaws as the first and second jaws are transitioned from the open to the closed state. ### Claim 4 (depends on 2) The apparatus of claim 2, wherein the external force is applied by presence of tissue between the first and second jaws as the first and second jaws are transitioned from the open to the closed state. ### Claim 5 (depends on 2) The apparatus of claim 2, wherein the range of angles is limited by the other of the first and second jaws. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the distal end returns to the first position upon cessation of the application of the external force. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the body is elastically deformable. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the proximal end of the body is affixed to a distal end of the one of the first and second jaws. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein the body is spaced apart from a distal end of the other of the first and second jaws when the body is in at least one of the first and second positions. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein the distal end is movable about an intermediate portion of the body distal to the proximal end and proximal to the distal end. ### Claim 11 (depends on 1) The apparatus of claim 1, wherein the intermediate portion is distal to a distal end of the other of the first and second jaws. ### Claim 12 (depends on 1) The apparatus of claim 1, wherein one of the first and second positions is configured for marching the first and second jaws through tissue. ### Claim 13 A surgical instrument comprising a handle, a shaft having a proximal end coupled with handle and a distal end coupled with an end effector, the end effector comprising: (a) a first jaw configured to receive a staple cartridge having staples disposed therein; (b) a second jaw comprising an anvil including a plurality of staple forming pockets configured to form the staples, wherein the first and second jaws are pivotably coupled at a proximal end so as to be capable of transitioning between an open state and a closed state to clamp and staple tissue with the staples; (c) a tip coupled with the second jaw such that a proximal end of the tip is longitudinally constrained relative to the second jaw, the tip comprising a body extending from the proximal end to a distal end; and wherein the distal end is moveable, via the application of a force external to the tip, from a first position, where the distal end is positioned at a first angle relative to the one of the first and second jaws, to a second position where the distal end is positioned at a second angle, different from the first angle, relative to the one of the first and second jaws, wherein when the first and second jaws are in the closed state without tissue present between the first and second jaws and the distal end is in the first position, the distal end contacts the other of the first and second jaws. ### Claim 14 (depends on 13) The surgical instrument of claim 13, wherein the distal end is moveable about a range of angles relative to the one of the first and second jaws, including the first and second angles. ### Claim 15 (depends on 14) The surgical instrument of claim 14, wherein the external force is applied by the other of the first and second jaws as the first and second jaws are transitioned from the open to the closed state. ### Claim 16 (depends on 14) The surgical instrument of claim 14, wherein the external force is applied by presence of tissue between the first and second jaws as the first and second jaws are transitioned from the open to the closed state. ### Claim 17 (depends on 14) The surgical instrument of claim 14, wherein the range of angles is limited by the other of the first and second jaws. ### Claim 18 (depends on 13) The surgical instrument of claim 13, wherein the distal end returns to the first position upon cessation of the application of the external force. ### Claim 19 (depends on 13) The surgical instrument of claim 13, wherein the body is elastically deformable. ### Claim 20 (depends on 13) The surgical instrument of claim 13, wherein the proximal end of the body is affixed to a distal end of the one of the first and second jaws. ### Claim 21 (depends on 13) The surgical instrument of claim 13, wherein the body is spaced apart from a distal end of the other of the first and second jaws when the body is in at least one of the first and second positions. ### Claim 22 (depends on 13) The surgical instrument of claim 13, wherein the distal end is movable about an intermediate portion of the body distal to the proximal end and proximal to the distal end. ### Claim 23 (depends on 13) The surgical instrument of claim 13, wherein the intermediate portion is distal to a distal end of the other of the first and second jaws. ### Claim 24 (depends on 13) The surgical instrument of claim 13, wherein one of the first and second positions is configured for marching the first and second jaws through tissue. ### Claim 25 An end effector for use with a handle or robotic am, the end effector comprising: (a) a first jaw configured to receive a staple cartridge having staples disposed therein; (b) a second jaw comprising an anvil including a plurality of staple forming pockets configured to form the staples, wherein the first and second jaws are pivotably coupled at a proximal end so as to be capable of transitioning between an open state and a closed state to clamp and staple tissue with the staples; (c) a tip coupled with the second jaw such that a proximal end of the tip is longitudinally constrained relative to the second jaw, the tip comprising a body extending from the proximal end to a distal end; and wherein the distal end is moveable, via the application of a force external to the tip, by one of the first jaw or tissue captured between the first and second jaws, about a range of angles relative to the second jaw, including a first angle relative to the second jaw and a second angle, different from the first angle, relative to the second jaw, wherein one of the first and second angles is configured for marching the first and second jaws through tissue, wherein when the first and second jaws are in the closed state without tissue present between the first and second jaws and the distal end is at the first angle, the distal end contacts the other of the first and second jaws.
