Assignee:

United States Surgical Corporation - Norwalk CT

International Classification:

A61M 500

US Classification:

604248

Abstract:

A cannula assembly for use in conjunction with endoscopic surgical techniques includes a cannula, a housing mounted on one end of the cannula, and a variable interior dimension cannula valve assembly in the housing. The variable interior dimension cannula valve assembly includes a flexible tubular member having a distal portion affixed to the housing, an intermediate portion capable of changing interior dimension and a proximate portion including a rigid rotating means and a locking means. The interior dimension of the cannula valve assembly may be set to a desired size to fit a surgical instrument inserted into the cannula passage while maintaining a substantially air-tight seal.

Assignee:

United States Surgical Corporation - Norwalk CT

International Classification:

A61M 500

US Classification:

604264

Abstract:

A port includes a body having a hollow portion defining an axial bore, a flange circumferentially disposed around a proximal end of the hollow portion and two spaced apart legs extending distally from the hollow portion, each leg having a distal end with a wing portion extending laterally therefrom. The thoracic port is inserted into the intercostal space between two ribs and turned to a locking position wherein the legs may advantageously bias the ribs to a more spaced apart configuration and the wings abut the distal surface of the ribs to prevent inadvertent withdrawal of the port.

Appl. No.:

8/073254

Inventors:

Thomas D. Guy - Fairfield CT
David T. Green - Westport CT

Assignee:

United States Surgical Corporation - Norwalk CT

International Classification:

A61B 1732

US Classification:

606185

Abstract:

A safety trocar is provided in which the cutting tip is withdrawn into the cannula in response to counterforce being removed from the cutting tip, e. g. , by the tip entering a body cavity. The cutting tip is maintained in the exposed positioned by a mechanism associated with the obturator shaft, and is automatically withdrawn into the cannula under the force of a spring when the first mechanism is released by a second mechanism associated with the obturator. Penetration force is maintained at a minimum and safe and efficacious trocar entry is facilitated.
