A modular trocar system which includes an obturator assembly, and a cannula assembly defining a longitudinal passageway therethrough configured and dimensioned to slidably receive the obturator assembly, the cannula assembly including a housing which includes a valve assembly and a first mating portion, and a cannula defining a passageway of a predetermined dimension therethrough, the cannula and housing movable alternately between a spaced apart relative orientation and an attached orientation wherein the first and second mating portions are engaged.

Modular trocar system and methods and assembly

Valve assembly for sealed reception of an elongated object includes a valve body having at least one opening configured and dimensioned to permit entry of an elongated object and defining a central longitudinal axis, an elongated seal member formed of a resilient material and defining an aperture in general alignment with the opening of the valve body whereby the aperture is configured and dimensioned such that insertion of the object into the aperture causes the resilient material defining the aperture to resiliently engage the outer surface of the object in a substantially fluid flight manner, and at least one elongated guard member disposed within the seal member in supporting contact with the inner surface thereof. The guard member is positioned to engage the elongated object upon at least partial insertion of the elongated object into the valve body. The guard member includes at least a first substantially rigid portion adapted to be displaced relative to the longitudinal axis to facilitate expansion of the aperture of the seal member upon entry of the object therein and a second portion having less rigidity than the first portion of the guard member to enhance passage of the elongated object through the valve body.

Valve system for cannula assembly

A surgical clip applying instrument is disclosed which includes a handle portion, a body extending distally from the handle portion and defining a longitudinal axis, and a plurality of surgical clips disposed within the body. A jaw assembly is mounted adjacent a distal end portion of the body. The jaw assembly includes first and second jaw portions movable between a spaced-apart and an approximated position. A clip pusher is provided to individually distally advance a distalmost surgical clip to the jaw assembly while the jaw portions are in the spaced-apart position. An actuator at least partially disposed within the body is longitudinally movable in response to actuation of the handle portion. A jaw closure member is positioned adjacent the first and second jaw portions to move the jaw portions to the approximated position. The actuator and the jaw closure member define an interlock therebetween to produce simultaneous movement of the actuator and the jaw closure member when the actuator is positioned adjacent the distal end portion of the body.

Apparatus for applying surgical clips

A modular trocar system is provided which includes an obturator assembly, and a cannula assembly defining a longitudinal passageway therethrough configured and dimensioned to slidably receive the obturator assembly, the cannula assembly including a housing which includes a valve assembly and a first mating portion, and a cannula defining a passageway of a predetermined dimension therethrough, the cannula including a second mating portion disposed thereon, the cannula and housing movable alternately between a spaced apart relative orientation and an attached orientation wherein the first and second mating portions are engaged. A method of assembly is also provided and includes the steps of connecting a shield member of a first predetermined configuration and dimension to a first housing section, attaching a knife blade assembly of a second predetermined configuration and dimension to the first housing section with a single motion wherein the attachment permits rotation of the knife blade relative to the first housing section, and attaching the first housing section to a second housing section with a quick connect mechanism which includes first and second mating portions such that the first and second housing sections are movable from a spaced apart position to a connected position in a single motion.
