## Abstract

The present invention generally relates to a retractor. Specifically, this invention relates to a malleable retractor designed to retract soft tissue and create a surgical opening to provide visualization of and access to the spine.

## Claims

### Claim 1

A retractor device comprising:
a base section;
two or more blades extending from said base section, wherein each of said blades has a first end attached to an outer edge of said base section and a second end that is opposite said first end;
one or more anchor ports formed in said base section;
wherein said one or more anchor ports are positioned between an inner edge of said base section and said outer edge of said base section;
wherein each of said blades has a curved shape; and
wherein said base section has circular shape and said curved shape of each of said blades corresponds to said circular share of said base section.

### Claim 2 (depends on 1)

The retractor device of claim 1, further comprising an aperture formed in said base section, wherein said aperture is defined by an inner edge of said base section.

### Claim 3 (depends on 1)

The retractor device of claim 1, wherein said one or more anchor ports are configured to engage with anchor members.

### Claim 4 (depends on 1)

The retractor device of claim 1, wherein said second end of each of said blades is configured to splay outward to expand a visualization and workable area.

### Claim 5 (depends on 1)

The retractor device of claim 1, wherein said first end of each of said blades is attached to said base section by a hinge.

### Claim 6 (depends on 5)

The retractor of claim 5, wherein said hinge is formed of a flexible material.

### Claim 7

A retractor device comprising:
a base section;
an aperture formed in said base section, wherein said aperture is defined by an inner edge of said base section;
two or more blades extending from said base section, wherein each of said blades has a first end attached to an outer edge of said base section and a second end that is opposite said first end;
one or more anchor ports formed in said base section;
wherein said one or more anchor ports are positioned between said inner edge of said base section and said outer edge of said base section;
wherein each of said blades has a curved shape; and
wherein said base section has circular shape and said curved shape of each of said blades corresponds to said circular shape of said base section.

### Claim 8 (depends on 7)

The retractor device of claim 7, wherein said one or more anchor ports are configured to engage with anchor members.

### Claim 9 (depends on 7)

The retractor device of claim 7, wherein said second end of each of said blades is configured to splay outward to expand a visualization and workable area.

### Claim 10 (depends on 7)

The retractor device of claim 7, wherein said blades are attached to said base section by hinges.

### Claim 11 (depends on 10)

The retractor of claim 10, wherein said hinges are formed of a flexible material.
