Abstract

A port for anchoring a cannula is provided. The port consists of a sealing cap removably attached to a threaded cone top. The threaded cone top is threaded onto a cone section from which a plurality of arms extend. The arms include a system for retaining a thread such as a suture. For use in laparoscopic surgery, a cannula is inserted into the port, the port is secured to the cannula and the cannula/port assembly is secured to the surgical site using sutures and a suture retaining system on the port.

Claims

1. A port comprising:

a sealing cap removably attached to a threaded cone top;

a cone having an upper threaded section for receiving the threaded cone top and a lower conical section; and

a pair of arms extending from the cone, each arm including a means for retaining a thread.

2. A port according to claim 1 wherein the cone further comprises an upper segmented section having a plurality of vertical segments, each of which is forced inward upon threading of the cone top onto the cone.

3. A port according to claim 1 wherein the retaining means is a plurality of O-rings.

4. A port according to claim 1 wherein the sealing cap is made from silicon rubber.

5. A port according to claim 3 wherein the O-rings are made from silicon rubber.

6. A port according to claim 1 wherein the cone is made from plastic.

7. A port according to claim 1 wherein the arms are made from stainless steel.

8. A port according to claim 1 wherein the arms attached to the cone using an epoxy adhesive.

9. A port according to claim 1 wherein the arms are T-shaped such that the end portions of each arm is substantially parallel to the surface into which the cannula will be placed.

10. A port according to claim 9 wherein the thread retaining means is located on the end portion of each arm.

11. A port according to claim 1 wherein the arms are bent such that the end portions of the arms are substantially parallel to the surface into which the cannula will be placed.

12. A port according to claim 11 wherein the thread retaining means is located on the end portion of each arm.
