A surgical access assembly includes a cannula, a valve housing attached to the cannula, and a valve assembly positioned in the valve housing. The valve assembly includes a centering mechanism with a hoop and fingers, a ring with a flange at one end of the ring, a retainer having first and second discs, a guard having a frame and flaps attached to the frame, and a seal with petals attached to a support. The guard is at least partially disposed in the first disc and the seal is at least partially disposed in the second disc.
Claims20
A valve assembly for use in a surgical access assembly, the valve assembly comprising:
- a guard including a frame and flaps flexibly coupled to the frame;
- a seal including a support and petals flexibly coupled to the support;
- a centering mechanism including a hoop and fingers, the fingers having first and second ends, the first ends of the fingers flexibly coupled to an outer surface of the hoop and the second ends of the fingers biased away from the outer surface;
- and
- a retainer having first and second discs, the first disc having a ridge, the second disc having a slot configured to receive the ridge in the slot, one of the first or second discs positionable in a passage defined by the hoop.
A valve assembly for use in a surgical instrument, the valve assembly comprising:
- a centering mechanism including a hoop having fingers extending radially outwards from an outer surface of the hoop, each finger being flexibly connected to the outer surface and biased away from the outer surface;
- a ring with an outer diameter and a flange, the flange disposed at a first end of the ring and an opposed second end of the ring abutting one end of the hoop;
- a first disc disposed in the ring;
- a second disc disposed in the hoop, the first disc attachable to the second disc irrespective of a rotational orientation of the first disc relative to the second disc;
- a guard including a frame and flaps flexibly coupled to the frame, the guard partially disposed in the first disc;
- and
- a seal including petals flexibly coupled to a support, the seal partially disposed in the second disc such that the frame and the support abut one another.
A valve assembly for use in a surgical instrument, the valve assembly comprising:
- a hoop having fingers extending radially from an outer surface of the hoop;
- a ring having an outer wall and a rim disposed at a distal end of the outer wall, the rim abutting a first surface of the hoop;
- a first disc;
- a second disc;
- a guard including a frame and flaps coupled to the frame, the guard disposed between the ring and the first disc;
- and
- a seal including petals coupled to a support, the seal disposed between the hoop and the second disc, the first disc attachable to the second disc irrespective of a rotational orientation of the first disc relative to the second disc.
