## Abstract

A laparoscopic knot pushing device having an elongated body with a first end adapted for gripping by a doctor, a planar face formed in the second end. The planar face is opposite the elongated body, and has a first side with a first rounded edge and a second rounded edge and the planar face is positioned 5 degrees to 20 degrees from the axis of the elongated body. The device further comprises a hole with a top and bottom rounded edges are disposed in the planar face aligned with the axis to the elongated body axis.

## Claims

### Claim 1

A laparoscopic knot pushing device, comprising:
a. an elongated body having an axis, a first end and a second end, wherein the first end is adapted for gripping by a user;
b. a planar face formed in the second end wherein the planar face is integral with the elongated body, and wherein the planar face has a first side with a first rounded edge and a second rounded edge, and wherein the planar face is positioned 5 degrees to 20 degrees from the axis of the elongated body; and
c. a hole with a top rounded edge and a bottom rounded edge disposed in the planar face aligned with the elongated body axis.

### Claim 2 (depends on 1)

The laparoscopic knot pushing device of claim 1, wherein the planar face is an integral portion of the elongated body forming a one-piece unit.

### Claim 3 (depends on 1)

The laparoscopic knot pushing device of claim 1, wherein the planar face removably engages the elongated body.

### Claim 4 (depends on 1)

The laparoscopic knot pushing device of claim 1, wherein the planar face has a width up to 9 millimeters and the hole in the planar face comprises a diameter between 1.5 millimeters to 7 millimeters.

### Claim 5 (depends on 1)

The laparoscopic knot pushing device of claim 1, wherein the elongated body has a diameter between 3 millimeters to 9 millimeters.

### Claim 6 (depends on 1)

The laparoscopic knot pushing device of claim 1, wherein the elongated body is hollow.

### Claim 7 (depends on 1)

The laparoscopic knot pushing device of claim 1, wherein the elongated body and planar face comprises surgical grade stainless steel or a sterilizable, non-deformable, impact resistant, stiff with some flexibility, polymer, graphite composite or a polymer with elastomer blend.

### Claim 8 (depends on 1)

The laparoscopic knot pushing device of claim 1, wherein the elongated body and planar face comprise an autoclavable non-deformable polymer disposed over a metal cylindrical body.

### Claim 9 (depends on 1)

The laparoscopic knot pushing device of claim 1, wherein the elongated body is generally rounded.

### Claim 10 (depends on 1)

The laparoscopic knot pushing device of claim 1, wherein the elongated body is tapered from a larger diameter at the first end to a smaller diameter at the second end.

### Claim 11 (depends on 1)

The laparoscopic knot pushing device of claim 1, wherein the first end is removably secured to the elongated body.

### Claim 12 (depends on 1)

The laparoscopic knot pushing device of claim 1, wherein the first end is scored for providing a more secure grip for the user.

### Claim 13 (depends on 1)

The laparoscopic knot pushing device of claim 1, wherein the planar face is tapered to a diameter between 20 percent to 80 percent less than the diameter of the elongated body.

### Claim 14 (depends on 1)

The laparoscopic knot pushing device of claim 1, wherein at least a portion of the first side of the planar face has a first rounded edge and a second rounded edge.

### Claim 15 (depends on 1)

The laparoscopic knot pushing device of claim 1, wherein a non-stick coating is disposed over the second end.

### Claim 16

An interchangeable laparoscopic knot pushing device comprising:
a. an elongated body having an axis, a removable first end and a second end, wherein the first end is a holding portion;
b. a planar face removably secured to the second end, wherein the planar face connects to the elongated body, and wherein the planar face has a first side with a first rounded edge and a second rounded edge and wherein the planar face is positioned 5 degrees to 20 degrees from the axis of the elongated body;
c. a hole with a top rounded edge and a bottom rounded edge disposed in the planar face aligned with the elongated body axis; and
d. a camera disposed in communication with the second end, and wherein the camera is adapted to removably engage the elongated body when the planar face is removed from the elongated body.

### Claim 17 (depends on 16)

The interchangeable laparoscopic knot pushing device of claim 16, further comprising: a targeting light disposed in communication with the second end and connected to a power supply, wherein the targeting light is adapted to be removable from the elongated body.

### Claim 18 (depends on 16)

The interchangeable laparoscopic knot pushing device of claim 16, wherein the elongated body is hollow for supporting cables and wires from the camera to a power supply.

### Claim 19 (depends on 16)

The interchangeable laparoscopic knot pushing device of claim 16, further comprises a channel disposed along the axis of the elongated body for containing the targeting light, the camera, cables, or combinations thereof.

### Claim 20

An interchangeable laparoscopic knot pushing device comprising:
a. an elongated body having an axis, a removable first end and a second end, wherein the first end is a holding portion;
b. a planar face removably secured to the second end, wherein the planar face connects to the elongated body, and wherein the planar face has a first side with a first rounded edge and a second rounded edge and wherein the planar face is positioned 5 degrees to 20 degrees from the axis of the elongated body;
c. a hole with a top rounded edge and a bottom rounded edge disposed in the planar face aligned with the axis to the elongated body axis; and
d. a targeting light disposed in communication with the second end, and wherein the targeting light removably engages the elongated body.
