## Abstract

A surgical retractor includes a blade and a handle. The blade has a top surface and a bottom surface. The handle extends at an angle from a proximal end of the blade. In one exemplary aspect, the retractor has one or more slip-resistant patterns molded into the blade, in order to prevent slippage of the retractor against patient tissue.

## Claims

### Claim 1

An illuminated surgical retractor, comprising:
a blade having a top surface and a bottom surface; and
a handle extending at an angle from a proximal end of the blade;
wherein the blade and handle are molded from a glass-fiber reinforced polymer, and

wherein the blade, handle, and curved section are molded from a glass-fiber reinforced polymer, and
wherein at least a portion of the bottom surface of the blade comprises an in-molded non-slip pattern.

### Claim 3

An illuminated surgical retractor, comprising:
a blade having a top surface and a bottom surface; and
a handle extending at an angle from a proximal end of the blade;
wherein the blade and handle are molded from a polymer, and
wherein at least a portion of the bottom surface of the blade comprises an in-molded non-slip pattern.

### Claim 4

An illuminated surgical retractor, comprising:
a blade having a top surface and a bottom surface; and
a handle extending at an angle from a proximal end of the blade;
wherein the blade and handle are molded from a polymer, and
wherein at least a portion of the blade comprises an in-molded non-slip pattern.

### Claim 5 (depends on 1)

The illuminated surgical retractor of claim 1, wherein:
the handle extends downwardly from the proximal end of the blade, and
the bottom surface of the blade faces in a downward direction.

### Claim 6 (depends on 2)

The illuminated surgical retractor of claim 2, wherein:
the at least one t source of the illumination assembly is configured to emit light along the top surface of the blade, and
the top and bottom surfaces of the blade are opposing surfaces.

### Claim 7 (depends on 3)

The illuminated surgical retractor of claim 3, wherein:
the handle extends downwardly from the proximal end of the blade, and
the bottom surface of the blade faces in a downward direction.

### Claim 8 (depends on 2)

The illuminated surgical retractor of claim 2, wherein the illumination assembly is permanently attached to the curved portion of the retractor.

### Claim 9 (depends on 2)
