Abstract

Various devices are provided for allowing multiple surgical instruments to be inserted through a single surgical access device at variable angles of insertion, allowing for ease of manipulation within a patient's body while maintaining insufflation. Safety shields and release mechanisms are also provided for use with various surgical access devices.

First claim

What is claimed is:

1 - 20 . (canceled)

21 . 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 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 third range of motion including vertical movement of the sealing element and the port housing as a unit relative to the retractor.

22 . The device of claim 21 , further comprising a connector disposed between the retractor and the housing, the connector being configured to flex in the vertical direction to allow the vertical movement of the sealing element and the port housing as a unit relative to the retractor, and the connector being configured to flex in a horizontal direction to allow the horizontal movement of the sealing element and the port housing as a unit relative to the retractor.

23 . The device of claim 22 , wherein the sealing element is configured to move in a fourth range of motion in which the sealing element and the port housing rotate as a unit in a horizontal plane relative to the retractor, and the connector is configured to rotate relative to the retractor to allow the fourth range of motion.

24 . The device of claim 22 , wherein the sealing element is configured to move in a fifth range of motion in which the sealing element and the port housing angularly adjust as a unit relative to a horizontal plane, and the connector is configured to flex relative to the retractor to allow the fifth range of motion.

25 . The device of claim 22 , wherein the connector is configured to allow the port housing and the sealing element to move in a full range of motion relative to the retractor.

26 . The device of claim 22 , wherein the housing is rotatable relative to the connector.

27 . The device of claim 21 , wherein the sealing element is configured to move in at least one of fourth and fifth ranges of motion, the fourth range of motion including the sealing element and the port housing rotating in a horizontal plane as a unit relative to the retractor, and the fifth range of motion including the sealing element and the port housing angularly adjusting as a unit relative to the horizontal plane.

28 . The device of claim 21 , further comprising a flexible membrane attached to the sealing element, the flexible membrane being configured to flex to allow the horizontal movement of the sealing element relative to the port housing and the retractor.

29 . 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; 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.

30 . The device of claim 29 , wherein the connector is configured to flex in a first vertical direction away from the retractor to increase the distance between the sealing element and the retractor and is configured to flex in a second vertical direction toward the retractor to decrease the distance between the sealing element and the retractor.

31 . The device of claim 29 , further comprising a flexible membrane attached to the sealing element, wherein the flexible membrane is configured to flex to provide the lateral floating of the sealing element.

32 . The device of claim 29 , further comprising a gimbal seating the sealing element therein.

33 . The device of claim 29 , wherein the housing is configured to rotate relative to the connector about the longitudinal axis of the lumen.

34 . 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, 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 angular adjustment of the sealing element relative to a horizontal plane and relative to 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 in the horizontal plane relative to the retractor, and the third range of motion including vertical movement of the sealing element and the port housing as a unit relative to the retractor.

35 . The device of claim 34 , further comprising a connector disposed between the retractor and the proximal housing, the connector being configured to flex in the vertical direction to allow the vertical movement of the sealing element and the port housing as a unit relative to the retractor, and the connector being configured to flex in a horizontal direction to allow the horizontal movement of the sealing element and the port housing as a unit in the horizontal plane relative to the retractor.

36 . The device of claim 35 , wherein the sealing element is configured to move in a fourth range of motion in which the sealing element and the port housing rotate in the horizontal plane as a unit relative to the retractor, and the connector is configured to rotate relative to the retractor to allow the fourth range of motion.

37 . The device of claim 35 , wherein the sealing element is configured to move in a fifth range of motion in which the sealing element and the port housing angularly adjust as a unit relative to the horizontal plane, and the connector is configured to flex relative to the retractor to allow the fifth range of motion.

38 . The device of claim 35 , wherein the connector is configured to allow the port housing and the sealing element to move in a full range of motion relative to the retractor.

39 . The device of claim 35 , wherein the housing is rotatable relative to the connector.

40 . The device of claim 34 , further comprising a gimbal attached to the sealing element, the gimbal being configured to move relative to the port housing to allow the angular adjustment of the sealing element relative to the horizontal plane and relativ
