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.

Trocar and cannula assembly having conical valve and related methods

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. The cap assembly also includes a valve positioned adjacent the opening of the valve housing. The valve includes a valve body with an annular-shaped valve opening for receiving elongate tools with differing diameters so that a seal is maintained between the valve opening and any of the plurality of elongate tools. The valve body includes a proximal valve section including a valve ring and positioned within the valve housing and includes a distal valve section extending axially from the proximal valve section. The distal valve section includes a valve extension having a proximal end portion, a distal end portion, and a substantially conically shaped medial portion connected to and extending therebetween. A valve opening is positioned in the distal end portion of the valve extension that is adapted to individually and separately receive the elongate tools so that when any one of the elongate tools is positioned through the valve opening, a seal is maintained between peripheries of the valve extension surrounding the valve opening and outer peripheries of the inserted elongate tool.

Combination medical clamp and medical coupler

A trocar system is provided which preferably includes a cannula having an elongate cannula body. The cannula body includes medial and distal portions thereof having a first diameter and a proximal portion thereof connected to the medial portion and having a second diameter. The second diameter is preferably larger or greater than the first diameter. A trocar having an elongate trocar body also extends through the cannula. The elongate trocar body has a sharpened distal end portion, a medial portion thereof having a first diameter, and a proximal portion having a second diameter. The second diameter is preferably larger or greater than the first diameter. The trocar also has a handle connected to a proximal end portion of the trocar body for gripping of and handling of the trocar by a hand of a user and a shield slidably mounted to the medial portion of the trocar body and biased in an extended position so that a distal end of the shield coveringly protects the sharpened distal end of the trocar body until pressure is applied thereagainst so that the shield slidably moves toward the proximal portion of the trocar body in a retracted position. The shield has a third diameter which is preferably at least equal to or less than the second diameter.

Trocar system having shielded trocar

A trocar system is provide which preferably has a cannula having an elongate cannula body. The cannula body includes medial and distal portions thereof having a first diameter and a proximal portion thereof connected to the medial portion and having a second diameter. The second diameter is preferably larger or greater than the first diameter. A pair of finger grips are each connected to and extending outwardly from the proximal portion of the cannula body for gripping the cannula with the fingers of a hand of a user. A trocar having an elongate trocar body is positioned to extend through the cannula body. The trocar also having a handle connected to the trocar body for gripping of and handling of the trocar by a hand of a user.
