## Abstract

Cannula anchor assemblies are disclosed which consist of a threaded cannula and a cannula anchor. The cannula anchor system allows for secure anchoring into the body wall, and proper cannula height adjustment prior to and during surgery. Sutures through the body wall may be secured to the cannula anchor either directly through the cannula anchor, or around suture posts attached therein. The cannula anchor also prevents excessive plunge of a trocar into the patient. The cannula anchor is generally configured with internal threads that mate with a threaded cannula.

## Claims

### Claim 1

A cannula anchor assembly comprising:
an internally threaded cannula insert positioned on a threaded cannula, the cannula insert positioned partially inside a suture cone and partially inside a cannula anchor;
wherein said suture cone includes one or more suture posts configured to wrap suture around.

### Claim 2 (depends on 1)

The cannula anchor assembly of claim 1, wherein a height of said threaded cannula relative to said internally threaded cannula insert can be adjusted by rotating clockwise.

### Claim 3 (depends on 1)

The cannula anchor assembly of claim 1, wherein a height of said threaded cannula relative to said internally threaded cannula insert can be adjusted by rotating counterclockwise.

### Claim 4 (depends on 1)

The cannula anchor assembly of claim 1, wherein said suture cone is configured to be penetrable by a suture needle.

### Claim 5 (depends on 1)

The cannula anchor assembly of claim 1, wherein said suture cone includes at least one finger grip.
