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.

Claims

1. A surgical access device, comprising:

a housing having a seal base;

a stage rotatably seated within the seal base and extending substantially co-planar with the seal base; and

a plurality of sealing ports extending through the seal base for receiving surgical instruments, the plurality of sealing port having a first sealing port that is seated within the stage and a second sealing port that is seated within the seal base and spaced a distance apart from the stage.

2. The surgical access device of claim 1, wherein the stage is rotatably disposed within an opening formed in the seal base.

3. The surgical access device of claim 1, wherein the seal base is rotatably seated within the housing.

4. The surgical access device of claim 1, further comprising a retractor extending distally from the housing and having an opening for receiving surgical instruments inserted through the plurality of sealing ports.

5. The surgical access device of claim 1, wherein each sealing port has a sealing element extending across a lumen thereof for receiving a surgical instrument.

6. The surgical access device of claim 1, wherein the plurality of sealing ports includes a third sealing port seated within the stage, and wherein the stage is rotatable to move the first, second, and third sealing ports between a substantially in-line configuration and a substantially triangular configuration.

7. A surgical access device, comprising:

a housing having a seal base;

a first sealing port extending through the seal base and configured to receive a surgical instrument therethrough; and

a second sealing port extending through the seal base and configured to receive a surgical instrument therethrough;

wherein the first sealing port is movable along a first path of rotation in which the first sealing port rotates about a central axis extending through a mid-point of the seal base, and the second sealing port is movable along a second path of rotation in which the second sealing port rotates about a second axis that is spaced radially outward from the center point of the seal base such that a distance between the first and second sealing ports can vary.

8. The surgical access device of claim 7, wherein the second sealing port is seated within a stage that is rotatably seated within the seal base, and wherein the stage rotates about the second axis.

9. The surgical access device of claim 7, further comprising a third sealing port extending through the seal base and configured to receive a surgical instrument therethrough, the third sealing port being movable along the second path of rotation such that a distance between the first and third sealing ports is adjustable.

10. The surgical access device of claim 7, further comprising a retractor extending from the housing and having an opening for receiving surgical instruments inserted through the first and second sealing ports.

11. The surgical access device of claim 7, wherein the first and second sealing ports each have a sealing element extending across a lumen thereof for receiving a surgical instrument.

12. The surgical access device of claim 7, wherein the seal base is rotatably seated within the housing.

13. A surgical access device, comprising:

a housing having a seal base; and

first, second, and third sealing ports extending through the seal base for receiving surgical instruments,

wherein the first sealing port and the second sealing port are simultaneously rotatable relative to the housing such that the first, second, and third sealing ports can be moved between a substantially in-line configuration and a substantially triangular configuration.

14. The surgical access device of claim 13, further comprising a retractor extending from the housing and having an opening for receiving surgical instruments inserted through the first, second, and third sealing ports.

15. The surgical access device of claim 13, wherein the seal base is rotatably seated within the housing.

16. The surgical access device of claim 13, further comprising a stage rotatably seated within the seal base, the first and second sealing ports being seated within the stage.

17. The surgical access device of claim 16, wherein the stage is disposed within an opening formed in the seal base.
