Abstract

Various embodiments of a laparoscopic trocar assembly are disclosed. The port assemblies include inserted parts that protect the patient'"'"'s tissues at the point of deployment. The port assemblies include seals for maintaining pneumoperitoneum both when instrument are being used and when instruments are not inserted.

Claims

1. A surgical port component comprising:

a body including;

a cylindrical portion formed by a plurality of sections or flaps, said cylindrical portion including at least one proximally extending projection at a proximal end thereof; and

a ring-shaped base member extending transversely across said cylindrical portion at the proximal end thereof, said ring-shaped base member including at least one slot configured and disposed to receive, at said proximal end of said cylindrical portion, said at least one proximally extending projection at said proximal end of said cylindrical portion, said sections or flaps being swingably coupled, at said proximal end of said cylindrical portion, to said ring-shaped base member when said at least one proximally extending projection of said cylindrical portion is received in said at least one slot of said ring-shaped base member, said at least one proximally extending projection extending proximally through said at least one slot of said ring-shaped base member such that said at least one proximally extending projection extends proximally from said ring-shaped base member when said at least one proximally extending projection of said cylindrical portion is received in said at least one slot of said ring-shaped base member,

said sections or flaps being made of at least a substantially rigid material, said ring-shaped base member including a plurality of upwardly or proximally extending arcuate flange sections receivable into a distal or lower end of a cylindrical body of a flexible-cannula port member.

2. The surgical port component defined in claim 1, further comprising an at least partially flexible skirt including a cylindrical proximal sleeve fitting over said sections or flaps, thereby coupling said skirt to said body.

3. The surgical port component defined in claim 1, wherein said sections or flaps are coupled to said ring-shaped base member after said at least one proximally extending projection of said cylindrical portion is received in said at least one slot of said ring-shaped base member.
