Variable surgical access device
First Claim
Patent Images
1. A surgical access device, comprising:
- a housing having a flexible base with a plurality of rigid sealing ports extending therethrough, each sealing port having a sealing element therein, the flexible base being movable to allow each sealing port to selectively position instruments extending through the sealing element at converging and diverging positions relative to one another, wherein the base has a resting position in which the base has a non-planar substantially convex configuration extending across the housing such that a proximal-most end of each sealing port is distal to a proximal-most end of the housing.

16. A surgical access device, comprising:
a housing having a retractor extending therefrom and configured to form a pathway through tissue and a plurality of rigid sealing ports having sealing elements therein for receiving surgical instruments therethrough, each sealing port being freely movable relative to one another, relative to the housing, and relative to tissue when the retractor is positioned in tissue such that a proximal-most end of each sealing port is movable between a position outside of the housing and a position within the housing. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. A surgical access device, comprising:
-
a housing having a plurality of sealing ports for receiving surgical instruments; a retractor having an opening formed therethrough for providing a pathway through tissue for surgical instruments inserted through the plurality of sealing ports; and a flexible connector configured to extend and compress in length, the connector being coupled between a distal end of the housing and a proximal end of the retractor that allows the housing to have a full range of lateral and vertical motion relative to the retractor. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32)
