Abstract

A percuscopic access device is disclosed. The percuscopic access device has a hollow shaft with a proximal opening and a distal opening. The percuscopic access device also has one or more barrier ridges on the outside of the hollow shaft. The percuscopic access device also has one or more recesses on the inside of the hollow shaft and in communication with the distal opening. A cleaning obturator for use with the percuscopic access device is also disclosed. The cleaning obturator and percuscopic access device may be combined as a surgical apparatus. The cleaning obturator has a guide rod having a proximal end and a distal end. The cleaning obturator also has a plugging tip on the distal end. The cleaning obturator further has one or more swab guides proximal to the plugging tip.

First claim

What is claimed is:

1. A cleaning obturator, comprising:
a guide rod having a proximal end and a distal end;
a plugging tip on the distal end;
one or more swab guides proximal to the plugging tip; and
a swab slideably engaged with the one or more swab guides, wherein the swab is arranged in a helix around at least a portion of the guide rod.

2. The cleaning obturator of claim 1 , wherein the helix rotates at least 360 degrees around the guide rod.

3. The cleaning obturator of claim 1 , wherein the swab passes at least 360 degrees around the guide rod.

4. The cleaning obturator of claim 1 , wherein the swab comprises two ends, at least one of which extends to the proximal end of the guide rod.

5. The cleaning obturator of claim 4 , further comprising a pull coupled to the at least one end of the swab extending to the proximal end of the guide rod.

6. The cleaning obturator of claim 5 , wherein the pull is configured to allow a user to advance a different portion of the swab through the one or more swab guides.

7. The cleaning obturator of claim 1 , further comprising a pull coupled to at least one end of the swab.

8. The cleaning obturator of claim 7 , wherein the pull is configured to allow a user to thread the swab through the one or more swab guides.

9. The cleaning obturator of claim 8 , wherein the pull is further configured to allow a user to advance a different portion of the swab through one or more swab guides.

10. The cleaning obturator of claim 1 , wherein the plugging tip is beveled.

11. The cleaning obturator of claim 1 , further comprising a phased handle adjacent the proximal end for interfacing with a percuscopic access device having a complementary phased handle.

12. A surgical kit, comprising:
a cleaning obturator, comprising:
a guide rod having a proximal end and a distal end;
a plugging tip on the distal end;
one or more swab guides proximal to the plugging tip; and
a swab slideably engaged with the one or more swab guides, wherein the swab is arranged in a helix around at least a portion of the guide rod; and

a percuscopic access device having:
a hollow shaft with a proximal opening and a distal opening;
one or more barrier ridges on the outside of the hollow shaft, the one or more barrier ridges each recessed with respect to the outside of the hollow shaft; and
one or more recesses on the inside of the hollow shaft and in communication with the distal opening.
