ABSTRACT:
A trocar system for endoscopic surgery, cap assembly, and related methods are provided. The cap assembly includes a valve housing with an opening formed in line with an axis of the valve housing and also includes a valve positioned adjacent the opening of the valve housing. The valve body includes a proximal valve section including a valve ring positioned within the valve housing, and a distal valve section extending axially from the proximal valve section. The distal valve section includes a valve extension having a proximal and distal end portions, and a substantially conically shaped medial portion connected to and extending therebetween, wherein a plurality of friction-reduction features, preferably tear-drop shaped knobs, are disposed proximate the distal end portion and extending a distance in the medial portion of the valve. A valve opening is positioned in the distal end portion of the valve extension, adapted to individually and separately receive the elongate tools so that when any one of the elongate tools of varying diameter is positioned therethrough, electrostatic adhesion between the valve and the tool is minimized and a seal is maintained between peripheries of the valve extension surrounding the valve opening and outer peripheries of the inserted elongate tool.
