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. A surgical device, comprising:
a substantially rigid housing having a plurality of sealing elements disposed therein, each of the sealing elements being configured to form a seal around a surgical instrument disposed therethrough; and
a retractor coupled to a distal end of the housing and extending distally therefrom, the retractor being configured to be positioned in tissue to form a pathway therethrough;
wherein each of the sealing elements is configured to be adjusted vertically relative to the housing, the retractor, and each of the other sealing elements.

2. The device of claim 1 , further comprising a base coupled to the housing and having the sealing elements seated therein in a first horizontal plane defined by a surface of the base, the vertical adjustment of a first one of the sealing elements moving the first one of the sealing elements to a second horizontal plane that is vertically offset from the first horizontal plane and is substantially parallel to the first horizontal plane, and the vertical adjustment of a second one of the sealing elements moving the second one of the sealing elements to a third horizontal plane that is vertically offset from the first and second horizontal planes and is substantially parallel to the first and second horizontal planes.

3. The device of claim 2 , wherein each of the sealing elements has a proximal face fixed in a horizontal position.

4. The device of claim 1 , wherein the plurality of sealing elements are configured to be adjusted vertically as a unit relative to the housing and the retractor.

5. The device of claim 4 , further comprising a base coupled to the housing and having the sealing elements seated therein; and
a flexible connector coupling the base to the housing, the flexible connector being configured to flex vertically to vertically adjust the sealing elements as a unit relative to the housing and the retractor.

6. The device of claim 4 , further comprising a base coupled to the housing and having the sealing elements seated therein in a first horizontal plane defined by a surface of the base, the vertical adjustment of the sealing elements as a unit moving the sealing element to a second horizontal plane that is vertically offset from the first horizontal plane and is substantially parallel to the first horizontal plane.

7. The device of claim 1 , wherein each of the sealing elements is configured to be adjusted horizontally relative to the housing, the retractor, and each of the other sealing elements.

8. A surgical device, comprising:
a housing having a single port configured to receive a surgical instrument therein, the port including an annular disc having a sealing element seated therein that is configured to form a seal around the surgical instrument, the sealing element being configured to rotate with the annular disc relative to the housing; and
an elongate member extending distally from the housing, the elongate member being configured to extend into a body cavity, and the elongate member being configured to receive the surgical instrument therein to allow the surgical instrument to enter the body cavity.

9. The device of claim 8 , wherein the sealing element is configured to rotate with the annular disc relative to the housing and the elongate member when the sealing element is forming the seal around the surgical instrument.

10. The device of claim 8 , wherein the port includes a flexible ring having the annular disc seated therein, and the housing includes a groove in which the flexible ring is seated and in which the sealing element and annular disc rotate relative to the housing.

11. The device of claim 8 , wherein the port includes a first ring proximal to the annular disc and a second ring distal to the annular disc, the first and second rings being configured to form a seal between the annular disc and the housing.

12. The device of claim 8 , wherein the elongate member is flexible.

13. The device of claim 8 , wherein the sealing element is configured to be selectively moved proximally and distally to adjust a position of the sealing element relative to the housing.

14. The device of claim 8 , wherein the sealing element is configured to be selectively moved laterally within the housing to adjust a position of the sealing element relative to the housing.

15. The device of claim 8 , wherein the sealing element is configured to move in a first range of motion, in which the sealing element is movable proximally and distally relative to the housing, and a second range of motion, in which the sealing element is movable laterally relative to the housing.

16. A surgical method, comprising:
positioning a retractor of an access device in tissue; and
moving a sealing element disposed in a sealing port of a housing of the access device horizontally relative to the housing and the port, the housing being proximal to the retractor in a vertical direction;
moving the sealing element and the port horizontally as a unit relative to the retractor and the housing; and
moving the sealing element and the port vertically as a unit relative to the retractor and the housing.

17. The method of claim 16 , wherein moving the sealing element and the port vertically as a unit includes flexing a connector that is disposed between the retractor and the housing, and moving the sealing element and the port as a unit horizontally includes flexing the connector.

18. The method of claim 16 , wherein moving the sealing element relative to the housing and the port includes flexing a flexible member attached to the sealing element.

19. The method of claim 16 , further comprising rotating the sealing element and the port in a horizontal plane as a unit relative to the retractor.

20. The method of claim 16 , further comprising angularly adjusting the sealing element and the port as a unit relative to a horizontal plane defined by the housing.
