Abstract: A surgical instrument for minimally invasive surgical procedures having a handle portion, an elongated body portion extending distally from the handle portion, an end effector movable between a first position and a second position, and an elongated tissue probe movably positioned within the elongated portion. The probe is movable between a retracted position and an advanced position, wherein movement of the probe moves the end effector from the first position to the second position.

Abstract: Access assemblies include an instrument valve housing and a valve assembly disposed within a cavity of the instrument valve housing. The valve assembly includes a guard assembly, and a seal assembly disposed adjacent to the guard assembly. The seal assembly includes first, second, third, and fourth seal sections. The first seal section is nested within the second seal section, the first and second seal sections are nested within the third seal section, and the first, second, and third seal sections are nested within the fourth seal section.

Abstract: A cannula for use in an access assembly includes an instrument valve housing including first and second housing sections and defining a cavity and a valve assembly disposed within the cavity of the instrument valve housing. The valve assembly includes a seal assembly including an outer flange and a septum seal extending across the outer flange, a guard assembly disposed within the outer flange of the seal assembly, and a centering mechanism. The guard assembly includes a plurality of guard members. Each guard member of the plurality of guard members includes a ring portion and a flap portion. The flap portions of the guard members of the guard assembly are configured to engage and stretch the septum seal during reception of a surgical instrument through the valve assembly.

Abstract: A cannula includes an instrument valve housing and a valve assembly disposed within the instrument valve housing. The valve assembly includes a seal assembly having at least one seal member including a ring portion and a septum seal extending across the ring portion. The valve assembly further includes a guard assembly and a centering mechanism. The guard assembly includes a plurality of guard members. Each guard member includes a ring portion, and a flap portion having first and second flap sections and a groove disposed between the first and second flap sections. The centering mechanism includes an annular ring and a plurality of spokes extending outwardly from the annular ring. The assemblies are supported within the annular ring which is disposed within the instrument valve housing. The flap portions of the guard members are configured to engage and stretch the septum seal during reception of a surgical instrument through the valve assembly.

Abstract: A port fixation device is disclosed and includes a body portion and a plug. The body portion includes a circular portion, a first tab, and a second tab. The circular portion defines an aperture which is configured to allow a surgical access port to extend therethrough. The first tab and the second tab are disposed in mechanical cooperation with the circular portion. Movement of the first tab with respect to the second tab from a first position to a second position causes a diameter of the aperture to change from a first size to a second size. The first size is smaller than the second size, and the first position of the first tab is its rest position. The plug is disposed in mechanical engagement with the body portion, and has sufficient elasticity to remain engaged with the body portion when the first tab is in the first position and in the second position.
