Abstract

A surgical port includes an end face with a channel extending through the end face. The channel has a cross section shaped to receive a surgical instrument cannula. A lateral wall extends around a perimeter of the end face. The lateral wall and end face enclose an open volume. A rim extends radially inward from the lateral wall and projects into the open volume. An apron portion extends radially outward from the lateral wall and in a direction axially away from the end face. Surgical systems may include surgical ports. Methods relate to using surgical ports.

First claim

What is claimed is:

1. A system, comprising:
a surgical port, comprising:
an end face comprising a channel extending through the end face, the channel having a cross section shaped to receive a surgical instrument cannula;
a lateral wall extending around a perimeter of the end face, the lateral wall and end face enclosing an open volume;
a rim extending radially inward from the lateral wall and projecting into the open volume; and
an apron portion extending radially outward from an outer perimeter of the lateral wall and in a direction axially away from the end face; and

a wound retractor, wherein the rim of the surgical port is configured to engage with the wound retractor.

2. The system of claim 1 , wherein:
the surgical port further comprises a sleeve extending from the end face into the open volume; and
the channel extends through the sleeve.

3. The system of claim 2 , wherein the sleeve extends axially beyond the rim.

4. The system of claim 2 , wherein the sleeve is tapered in a direction extending away from the end face into the open volume.

5. The system of claim 1 , wherein the surgical port further comprises a bellows portion defining a portion of the channel.

6. The system of claim 1 , wherein the apron portion comprises an outer perimeter and a relief extending radially inward from the outer perimeter.

7. The system of claim 1 , wherein:
the lateral wall extends from the end face to a free end of the lateral wall; and
the apron portion extends radially outward from the free end of the lateral wall.

8. The system of claim 1 , wherein:
the channel is a first channel;
the surgical port further comprises a second channel extending through the end face; and
the cross section of the second channel is different from the cross section of the first channel.

9. The system of claim 8 , wherein the second channel has a cross section shaped to receive a cannula associated with an endoscopic imaging device.

10. The system of claim 1 , wherein the apron portion is deflectable from a first position in which the apron portion extends radially outward relative to the lateral wall and axially away from the end face to a second position in which the apron portion is deflected in a direction axially toward the end face and radially outward relative to the first position.

11. The system of claim 1 , wherein the surgical port comprises at least a first portion comprising an electrically insulating first material and at least a second portion comprising an electrically conductive second material.

12. The system of claim 11 , wherein the first material comprises silicone rubber.

13. The system of claim 11 , wherein the second material comprises electrically conductive particles dispersed in silicone rubber.

14. A system comprising:
a surgical port, comprising:
an end face comprising a channel extending through the end face, the channel having a cross section shaped to receive a surgical instrument cannula;
a lateral wall extending around a perimeter of the end face, the lateral wall and end face enclosing an open volume;
a rim extending radially inward from the lateral wall and projecting into the open volume; and
an apron portion extending radially outward from the lateral wall and in a direction axially away from the end face; and

a wound retractor, wherein the rim of the surgical port is configured to engage with the wound retractor,
wherein the surgical port comprises at least a first portion comprising an electrically insulating first material and at least a second portion comprising an electrically conductive second material, and
wherein the first portion of the surgical port extends from an interior surface of the channel to a surface of the apron portion.

15. A method, comprising:
positioning a wound retractor within an incision in a patient's body wall;
coupling a surgical port with the wound retractor;
positioning a flexible apron portion of the surgical port against an outer surface of the patient's body wall; and
inserting a surgical instrument cannula through the surgical port to provide access to a remote surgical site.

16. The method of claim 15 , wherein coupling the surgical port with the wound retractor comprises engaging a structure of the surgical port in an interference fit with a retraction ring of the wound retractor.

17. The method of claim 15 , wherein coupling the surgical port with the wound retractor comprises engaging a radially inwardly extending rim of the surgical port with a retraction ring of the wound retractor.

18. The method of claim 15 , wherein positioning the flexible apron portion of the surgical port against an outer surface of the patient's body wall comprises deflecting the flexible apron portion radially outwardly such that a distal surface of the flexible apron portion rests against the outer surface of the patient's body wall.

19. The method of claim 18 , wherein positioning the flexible apron portion of the surgical port against an outer surface of the patient's body wall further comprises deflecting the apron portion axially toward an end face of the surgical port.
