DISCRETE FLEXION HEAD FOR SINGLE PORT DEVICE
First Claim
1. A surgical access device, comprising:
- an outer housing having proximal and distal ends with a lumen extending therethrough; and
a plurality of discrete housing portions disposed across the proximal end of the outer housing and spaced a distance apart from one another, each housing portion having an opening extending therethrough and in communication with the lumen in the outer housing, and the plurality of housing portions being coupled by a flexible member such that each housing portion is independently movable relative to one another.

Abstract
Methods and devices are provided for accessing a body cavity. A surgical access device can be configured to be positioned in tissue to provide access through a working channel of the device to a body cavity underlying the tissue. The device can include a flexible member and a plurality of discrete housing portions disposed in at least a proximal portion of an outer housing. Each of the discrete housing portions can be surrounded by the flexible member within the outer housing and be configured to move therein relative to one another and to the outer housing. The flexible member can be configured to act as a barrier between the discrete housing portions such that when one of the discrete housing portions moves, the flexible member can flex to allow the other discrete housing portions to remain in a substantially fixed position relative to the outer housing.

11. A surgical access device, comprising:
-
an annular ring defining a lumen; a plurality of discrete housing portions disposed within the ring and defining channels between each of the housing portions, each housing portion having at least one sealing port configured to receive an instrument inserted therethrough and into the lumen; and a flexible member disposed in the channels such that each of the housing portions can move relative to one another in a plane transverse to a longitudinal axis of the ring. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method for providing access through tissue to a body cavity, comprising:
-
positioning a retractor in an opening in tissue of a patient such that a distal end of the retractor is positioned in a body cavity underlying the tissue, the retractor having an annular ring coupled to a proximal end thereof, the annular ring defining a lumen; inserting an instrument into the body cavity through one of a plurality of discrete housing portions disposed in the lumen of the annular ring such that none of the discrete housing portions directly contact one another; and laterally moving the instrument relative to the annular ring, thereby moving the one of the housing portions relative to each of the other housing portions. - View Dependent Claims (18, 19)
