Dissection tip and introducer for surgical instrument

摘要

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.

主权项

1. An introducer member comprising:
a body having a proximal portion and a distal portion, the proximal portion including an outer layer and an inner layer which collectively define a cavity, the proximal portion defining a hollow which is configured to receive a portion of an end effector, the body defining a passage which is in fluid communication with the cavity, and a port supported on the body, the port being configured to facilitate inflation of the cavity, wherein prior to inflation of the cavity the hollow defines a transverse dimension that is smaller than the transverse dimension defined by the component of the end effector to which the introducer member is to be attached.
