Abstract
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 surgical access assembly comprising:
- a cannula;
- a valve housing coupled to a proximal end of the cannula;
- and
- a valve assembly disposed in the valve housing, the valve assembly including:
- 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 disposed at one end of the ring, the other end of the ring abutting one end of the hoop;
- a retainer having a first disc disposed in the ring and a second disc disposed in the hoop, the first disc attachable to the second disc irrespective of the rotational orientation of the first disc relative to the second disc;
- a guard including a frame and flaps flexibly coupled thereto, 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.
A valve assembly for use in a surgical access assembly, the valve assembly comprising:
- a guard including a frame and flaps flexibly coupled thereto;
- a seal including a support and petals flexibly coupled thereto;
- 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 therein, one of the first or second discs positionable in a passage defined by the hoop.
A surgical access assembly comprising:
- a valve housing;
- a cannula extending from the valve housing;
- and
- a valve assembly disposed in the valve housing, the valve assembly including:
- a centering mechanism having a hoop and fingers extending radially from the hoop;
- a guard with a frame and flaps coupled to the frame, the guard disposed on a first side of the centering mechanism;
- a seal with a support and petals coupled to the support, the seal disposed on a second side of the centering mechanism;
- and
- a retainer including first and second discs, the guard coupled to the first disc in a fixed orientation, the seal coupled to the second disc in a fixed orientation, the first disc attachable to the second disc irrespective of the rotational orientation of the first disc relative to the second disc.
