Nathanson Liver Retractor: Flexible Retracting System for Laparoscopic Surgery

What Is a Nathanson Liver Retractor?

In laparoscopic and minimally invasive surgery, clear exposure of the operative field is everything. The Nathanson liver retractor is a specialized table-mounted retracting system designed to gently lift and hold the liver out of the way, giving surgeons an unobstructed view of the gallbladder, stomach, esophagus, and surrounding upper abdominal anatomy.

Unlike handheld retractors that require a dedicated assistant, the Nathanson system stays locked in position on its own, delivering stable, hands-free retraction throughout the procedure. An articulated gooseneck arm mounts to the operating table, while a curved hook blade cradles the edge of the liver. Once positioned, the arm holds its shape and keeps the organ securely retracted with steady, even pressure. This simple, dependable mechanism has made the Nathanson retractor a staple in operating rooms performing advanced laparoscopic surgery around the world.

Key Features of the Nathanson Retracting System

Flexible & Articulated Gooseneck Arm

The heart of the system is its flexible gooseneck arm, which can be bent, angled, and locked into virtually any position. This controlled positioning lets the surgeon fine-tune the direction and force of retraction with one hand, then leave the arm fixed for the rest of the case — no assistant fatigue, no drift, no constant readjustment.

Interchangeable Curved Hook Blades

The curved hook blades are interchangeable and available in multiple sizes, so they can be swapped quickly to match patient anatomy and procedural requirements. A single system therefore serves a wide range of surgical needs, from slim patients to bariatric cases that demand deeper reach and stronger lift.

Gentle & Stable Liver Retraction

The broad, curved blade distributes pressure evenly across the liver surface, reducing the risk of tissue trauma or capsular tears. Retraction remains rock-steady for the entire procedure, improving exposure and visibility exactly where the surgeon needs it most.

Stainless Steel Construction — Reusable and Durable

Manufactured from premium surgical-grade stainless steel, the Nathanson system is fully reusable and engineered to withstand repeated autoclave sterilization cycles without corrosion or loss of function. That durability makes it a cost-effective, long-term investment for hospitals, surgical centers, and distributors.

Clinical Applications

The Nathanson liver retractor is widely used across upper abdominal laparoscopy, including:

• Laparoscopic cholecystectomy: retracting the liver to expose the gallbladder and Calot’s triangle safely.
• Bariatric surgery: lifting the left liver lobe during sleeve gastrectomy and gastric bypass to access the stomach and gastroesophageal junction.
• Upper GI procedures: fundoplication, hiatal hernia repair, and other foregut operations where stable, hands-free liver retraction is essential.
