Dissection tip and introducer for surgical instrument
A surgical fastener applying apparatus includes an elongate body portion having proximal and distal ends, an end effector including a first movably coupled to a second jaw that is positioned at the distal end of the elongate body portion, and an introducer member. The introducer member has proximal and distal portions, and is configured and dimensioned for releasable connection with the end effector. The introducer member is at least partially formed from a flexible material, and is configured and dimensioned to separate target tissue from collateral tissue prior to positioning of the target tissue between the first and second jaws of the end effector.
1. An end effector of a surgical fastener applying apparatus, comprising:
a first jaw defining a longitudinal axis;
a pivot plate secured to an outer surface of the first jaw;
a second jaw movably coupled to the first jaw; and
an introducer member pivotably coupled to the pivot plate, the introducer member coupled to the first jaw and being configured to separate target tissue from collateral tissue, wherein the introducer member is laterally movable relative to the first jaw.
2. The end effector according to claim 1 , wherein the introducer member is movable between a first position in which a longitudinal axis defined by the introducer member is aligned with the longitudinal axis defined by the first jaw, and a second position in which the longitudinal axis of the introducer member is angled relative to the longitudinal axis of the first jaw.
3. The end effector according to claim 1 , wherein the introducer member is movable between a first position in which a distal portion of the introducer member is aligned with the first jaw, a second position in which the distal portion of the introducer member is laterally offset from a first lateral side of the first jaw, and a third position in which the distal portion of the introducer member is laterally offset from a second lateral side of the first jaw.
4. The end effector according to claim 1 , wherein the introducer member has a proximal portion pivotably coupled to the first jaw.
5. The end effector according to claim 1 , wherein the introducer member is pivotable relative to the first jaw.
6. The end effector according to claim 1 , wherein the introducer member has a proximal portion and a distal portion and a curvature defined therebetween.
7. The end effector according to claim 6 , wherein the distal portion of the introducer member curves from the first jaw toward the second jaw.
8. The end effector according to claim 7 , wherein the proximal portion of the introducer member extends in parallel relation to the first jaw and the distal portion of the introducer member extends in non-parallel relation to the first jaw.
9. The end effector according to claim 7 , wherein the proximal portion of the introducer member is supported on a top surface of the first jaw and the distal portion of the introducer member extends across a distal tip of the first jaw.
10. The end effector according to claim 7 , wherein the distal portion of the introducer member is disposed distally of the first and second jaws.
11. The end effector according to claim 1 , further comprising a pivot member pivotably secured to the pivot plate, wherein the introducer member is pivotably coupled to the pivot plate via the pivot member.
12. The end effector according to claim 1 , wherein the first jaw is an anvil and the second jaw is a surgical fastener cartridge.
13. The end effector according to claim 1 , wherein the first jaw is a surgical fastener cartridge and the second jaw is an anvil.
14. The end effector according to claim 1 , wherein the introducer member is fabricated from a pliable, biocompatible material.
