Abstract

A flexible surgical access port is provided that includes a flexible body. The flexible body is configured to elastically expand in response to passage of a surgical equipment therethrough, and thus retracts as the surgical equipment moves past. Thus, the flexible body can provide a surgical access path through Kambin's Triangle, and large surgical equipment passed through the flexible body does not compress the exiting nerve or the traversing nerve root for a prolonged period of time.

Claims (19)

1 . A surgical method, comprising:

inserting a flexible body of a flexible surgical access port through an incision in a patient's skin;

advancing the flexible body through Kambin's triangle to a position adjacent to an intervertebral disc space of the patient;

passing a surgical device through the flexible surgical access port, wherein movement of the surgical device through the flexible surgical access port causes the flexible surgical access port to both 1) elastically expand radially from a first configuration, and 2) move toward the first configuration after the surgical device has passed through; and

performing a surgical procedure on the intervertebral disc space using the surgical device.

2 . The method of claim 1 , further comprising transmitting light along the flexible surgical access port through one or more fiber optics extending along a length of the flexible surgical access port.

3 . The method of claim 1 , further comprising monitoring loads imparted to tissue adjacent the flexible surgical access port using one or more sensors disposed along a length of the flexible surgical access port.

4 . The method of claim 1 , further comprising monitoring nerve health in tissue adjacent the flexible surgical access port using one or more wires extending along a length of the flexible surgical access port.

5 . The method of claim 1 , wherein the flexible surgical access port is woven.

6 . The method of claim 1 , wherein the flexible surgical access port is nonwoven.

7 . The method of claim 1 , wherein the surgical device comprises a camera.

8 . The method of claim 1 , further comprising removing a portion of a patient's vertebra using the surgical device.

9 . The method of claim 1 , further comprising clearing the intervertebral disc space using the surgical device.

10 . The method of claim 1 , wherein the passing step comprises passing a spinal fusion cage through the flexible surgical access port and into the intervertebral disc space through Kambin's triangle.

11 . The method of claim 1 , further comprising anchoring the flexible body to anatomical tissue.

12 . The method of claim 1 , further comprising the step of rolling the flexible body over a collar so as to adjust a length of the flexible body.

13 . The method of claim 1 , wherein the flexible body extends along a central axis, and a majority of the radial elastic expansion occurs at a first side of the central axis compared to a second side of the central axis that is opposite the first side.

14 . The method of claim 13 , further comprising anchoring the flexible body to anatomical tissue at only the second side of the central axis.

15 . The method of claim 1 , wherein the flexible surgical access port moves to the first configuration after the surgical device has passed through.
