Dissection tip and introducer for surgical instrument
First Claim
1. A surgical fastener applying apparatus comprising:
- an elongate body portion having proximal and distal ends;
an end effector positioned at the distal end of the elongate body portion, the end effector including a first jaw movably coupled to a second jaw such that target tissue is positionable therebetween, one of the first jaw and the second jaw terminating in a dissector tip;
a connector member having proximal and distal ends, the proximal end being configured and dimensioned for releasable engagement with the end effector at the dissector tip; and
an introducer member having proximal and distal portions, the proximal portion being configured and dimensioned for releasable engagement with the connector member, the introducer member being configured and dimensioned to separate the target tissue from collateral tissue prior to positioning of the target tissue between the first and second jaws of the end effector, the connector member being formed from a first material, and the introducer member being formed from a second material, the first material being more rigid than the second material.

Abstract
The present disclosure describes a surgical fastener applying apparatus that 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.

- 11. A guide for use with a surgical fastener applying apparatus comprising an end effector including first and second movable jaws, the guide being configured and dimensioned to separate target tissue from collateral tissue prior to positioning of the target tissue between the first and second jaws, the guide including an introducer member longer than each of the first and second jaws, and a connector member being configured and dimensioned for releasable, contemporaneous engagement with a dissector tip of the end effector and with the introducer member such that the connector member is positionable between the end effector and the introducer member to releasably couple the introducer member to the end effector, wherein the connector member is formed from a biocompatible material suitable for contact with a patient'"'"'s internal tissue during a surgical procedure that is more rigid than the introducer member.
