## Abstract

The surgical retractor includes an elongated shaft, a handle at a proximal end of the elongated shaft; and an illuminating LED light, wherein the elongated shaft is capable of having up to four bends, with the illuminating LED light located on the elongated shaft adjacent to one of the up to four bends. The elongated shaft may be formed from an elastically deformable material. The elongated shaft can have four bends configured such that the distal end of the elongated shaft is parallel to the proximal end of the elongated shaft. The surgical retractor may be configured for use in a laparotomy.

## Claims

### Claim 1

A surgical retractor, comprising:
an elongated shaft;
a handle at a proximal end of the elongated shaft; and
an illuminating LED light,
wherein the elongated shaft has four bends, with the illuminating LED light located on the elongated shaft adjacent to a second bend of the four bends,
wherein each of the four bends is bent at an angle of about 30 to about 45 degrees, and
wherein a distance from a distal end of the elongated shaft to a fourth bend of the four bends of the elongated shaft is shorter than a distance from a first bend of the four bends of the elongated shaft to the proximal end of the elongated shaft.

### Claim 2 (depends on 1)

The surgical retractor of claim 1, wherein the fourth bend of the four bends is located close to the distal end of the elongated shaft.

### Claim 3 (depends on 1)

The surgical retractor of claim 1, wherein the four bends are configured such that the distal end of the elongated shaft is parallel to the proximal end of the elongated shaft.

### Claim 4 (depends on 1)

The surgical retractor of claim 1, configured for conducting a laparotomy.

### Claim 5 (depends on 4)

The surgical retractor of claim 4, wherein the laparotomy is conducted in a patient's abdominal cavity.

### Claim 6 (depends on 1)

The surgical retractor of claim 1, wherein the elongated shaft comprises an elastically deformable material.

### Claim 7 (depends on 1)

The surgical retractor of claim 1, wherein the elongated shaft comprises steel, steel alloy, aluminum, titanium, plastic, ceramic, fluidized metal, or any combination thereof.
