Abstract

Methods and devices are provided for providing surgical access into a body cavity. In one embodiment, a surgical access device is provided that includes a housing coupled to a retractor. The housing can be have one or more movable sealing ports for receiving surgical instruments. Each movable sealing port can include one or more sealing elements therein for sealing the port and/or forming a seal around a surgical instrument disposed therethrough. Each movable sealing port can be rotatable relative to the housing and each sealing element can be rotatable relative to the housing along a predetermined orbital path.

Claims

1. A surgical device, comprising:

a proximal housing having a base seated therein, the base having a first opening formed therein, the first opening having a first sealing element disposed therein that is configured to form a seal around a first surgical instrument inserted therethrough, the first opening having a first longitudinal axis;

a distal retractor configured to be positioned within tissue, the distal retractor having a working channel extending therethrough configured to receive the surgical instrument inserted through the first sealing element, the working channel having a second longitudinal axis that is substantially parallel to the first longitudinal axis; and

an intermediate base located between and coupled to the proximal housing and the distal retractor, the intermediate base having a second opening formed in a sidewall thereof, the second opening having a second sealing element disposed therein that is configured to form a seal around a second surgical instrument inserted therethrough, the second opening having a third longitudinal axis that is angularly offset from the first and second longitudinal axes.

2. The device of claim 1, wherein the base is configured to rotate relative to the proximal housing and the intermediate base.

3. The device of claim 1, wherein the first sealing element is configured to rotate within the first opening relative to the base and the intermediate base.

4. The device of claim 1, wherein the proximal housing is removably and replaceably coupled to the intermediate base and the distal retractor.

5. The device of claim 1, wherein the base has a third opening formed therein, the third opening having a third sealing element disposed therein that is configured to form a seal around a third surgical instrument inserted therethrough, the third opening having a fourth longitudinal axis that is substantially parallel to the first and second longitudinal axes and angularly offset from the third longitudinal axis.

6. The device of claim 1, wherein the second sealing element is seated at a fixed position in the second opening such that the angular offset of the third longitudinal axis is fixed.

7. The device of claim 1, wherein the second sealing element is movably seated in the second opening such that the angular offset of the third longitudinal axis is adjustable.
