The McCulloch lumbar retractor is a surgical instrument system designed to hold back tissues during lumbar spine surgery, providing surgeons with better visibility and access to the surgical site. Key features include jointed and adjustable arms, which can fold for unobstructed access, and a variety of interchangeable blades that are often color-coded for quick identification and available in narrow and wide options. Many modern systems use radiolucent or blackened blades to reduce glare and allow for clear X-rays during surgery.
