摘要：
A trocar or surgical port assembly includes an annular body attachable to a patient at an incision in a patient. The annular body includes a cylindrical insert portion defining a proximal end and a distal end and a flange disposed at the proximal end of the cylindrical insert portion. A skirt is attached to the distal end of the cylindrical insert portion and extends distally from the annular body and includes a flexible web and a wire attached to the flexible web that in a multiple looped configuration of non-intersecting curved portions positioned in the vicinity of the distal portion of the skirt to enable the flexible web to be biased via a biasing force exerted by the wire into a funnel-shaped open configuration having an opening of the skirt at the distal portion of the skirt that is larger than an opening of the skirt at the proximal portion.
