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.
