1. A surgical device, comprising:
- a housing including a port housing having a sealing element disposed therein, the sealing element being configured to form a seal around a surgical instrument disposed therethrough; and
a retractor mated to the housing such that the retractor is below the housing in a vertical direction, the retractor being configured to be positioned within a tissue opening, and the retractor having a lumen extending therethrough, the lumen being configured to receive therein the surgical instrument disposed through the sealing element;
wherein the sealing element is configured to move in first, second, and third ranges of motion, the first range of motion including horizontal movement of the sealing element relative to the housing, the port housing and the retractor, the second range of motion including horizontal movement of the sealing element and the port housing as a unit relative to the retractor and the housing, and the third range of motion including vertical movement of the sealing element and the port housing as a unit relative to the retractor and the housing.

10. A surgical device, comprising:
-
a housing including a port having a sealing element disposed therein, the sealing element being configured to form a seal around a surgical instrument disposed therethrough; a retractor having a lumen extending therethrough, the lumen having a longitudinal axis, and the retractor being configured to be positioned within a tissue opening; a flexible membrane attached to the sealing element; and a connector mated to a distal portion of the housing and a proximal portion of the retractor, the connector being configured to flex to change a distance between the sealing element and the retractor and to flex to laterally move the sealing element relative to the longitudinal axis of the lumen; wherein the sealing element is configured to float laterally within the housing relative to the housing, the connector, and the retractor, the flexible membrane being configured to flex to provide the lateral floating of the sealing element. - View Dependent Claims (11, 12, 13)
