Apparatus facilitating suturing in laparoscopic surgery
First Claim
1. An apparatus for facilitating suturing of minimally invasive surgery puncture wounds comprising:
- a body defining a longitudinal axis, said body having a first end and a second end, said first end being adapted to be inserted into a puncture wound, said body including a pair of arms extending generally parallel to said axis from said second end to a point intermediate said first end and said second end, said pair of arms defining a recess therebetween, a portion of said recess most adjacent said first end being inclined so as to have decreasing depth toward said first end; and
a reinforcement segment extending between said pair of arms.

Abstract
A plug for use in minimally invasive surgery which includes recesses for facilitating suturing of a trocar insertion site. The plug may be inserted in an axial bore of a separate gripper housing, and fixed in place by the gripping structure of the housing or a first end of the plug may be inserted directly into the trocar insertion site after a trocar is removed. The plug is provided with a pair of opposed, longitudinally extending recesses formed in the outer surface thereof. Each recess extends from a second end of the plug to a point between the first end and the second end of the plug. The recess may cooperate to form a single slot in the plug defined by a pair of axially extending arms. The plug is also provided with reinforcing segments which extend between the arms for stabilization.

15. An apparatus for facilitating suturing of minimally invasive puncture wounds, said apparatus comprising:
-
a body having a generally cylindrical shape defining a longitudinal axis, said body defining a first end of said apparatus, said body defining a longitudinal axial bore therethrough; a pair of arms extending from said body to define a second end of said apparatus; an outer surface having a longitudinally extending recess formed therein and positioned between said pair of arms, said recess extending from said second end of said apparatus to a first plane, said first being perpendicular to said longitudinal axis of said apparatus and located intermediate said first and second ends, said apparatus and inclined toward said outer surface, said sloped surface extending from said first plane to a first point located on said outer surface of said apparatus, wherein said first point is located intermediate said first plane and said first end of said apparatus; reinforcement segments extending between said pair of arms; a plurality of ribs formed on said outer surfaces; a lug extending radially outwardly from one of said arms; and a seal operatively coupled to said first end of said apparatus, said seal covering said longitudinal axial bore, said seal having an incision in a central portion of said seal, said incision defining a pair of flaps.
