Choosing an abdominal retractor for open laparotomy

Updated 14 October 2026 · 3 min read

An abdominal retractor holds the wound open so that the surgical team can work in the peritoneal cavity with both hands free. The choice among frame-type patterns such as Balfour, Kirschner, Gosset and Mikulicz affects exposure, set-up time and the number of assistants needed. This guide explains how these retractors work, how to select blades and sizes, and what to check before ordering.

How self-retaining abdominal retractors work

A self-retaining abdominal retractor uses a frame or rack that holds side blades under tension, so the wound stays open without an assistant holding it. A centre blade is often added to retract the bladder, bowel or other structures in the lower abdomen.

This frees the assistants to use hand-held retractors where extra exposure is needed. In long procedures, frames reduce fatigue and keep the field steadier than hand-held alternatives. For general principles see surgical retractor types and self-retaining retractors.

Compare the cost of a frame against the staff time it saves: in procedures where two assistants would otherwise hold retractors, a self-retaining frame often pays for itself in flexibility.

Balfour and Kirschner patterns

The Balfour retractor is the classic frame for laparotomy. Two lateral blades slide on a frame and are locked by a rack, and a removable centre blade is added when needed. REDA lists Balfour and Kirschner abdominal retractors in its retractor range.

Specify the blade lengths and widths carefully. Blades are available in different depths so that the retractor can adapt to a thin or deep abdominal wall. Check that the frame is rigid, that the rack engages firmly and that blades lock in position without flexing.

  • Optional centre blade for lower abdominal exposure
  • Interchangeable blades in several depths

Gosset, Mikulicz and other classic designs

Gosset and Mikulicz retractors are classical abdominal patterns that appear in many surgical traditions. The Gosset is a self-retaining retractor with a rack for the lateral blades, and the Mikulicz is a frame-type design used for wide exposure. Ask which patterns your surgeons use and whether your supplier offers the exact variants.

If your teams are used to a specific pattern, keep it. Standardising on one pattern per department reduces training time and helps with sterile processing.

Selecting blades, sizes and accessories

Choose blade width and depth to match the abdominal wall thickness and the incision size. Smooth, rounded blade tips reduce the risk of pressure injury to the bowel and abdominal wall. Consider padded or atraumatic blade options if your supplier provides them.

Plan for the full system: frame, set of lateral blades, centre blade, spare blades and a storage tray. Compare with hand-held patterns such as Langenbeck and Farabeuf retractors, which supplement frames in deep fields.

Also check that blades can be removed and replaced individually, so that a damaged blade does not take the whole frame out of service.

Reprocessing, inspection and ordering

Disassemble the frame for cleaning, since racks and sliding parts trap debris. Inspect the rack teeth, blade connections and hinges for wear after every cycle. A frame that slips under load is unsafe and should go for repair.

When planning laparotomy trays, see our laparotomy instrument set guide for how a retractor fits into the wider set. Beckfinity can quote REDA abdominal retractors with the blades you need. Contact our specialists to request a quotation.

Frequently asked questions

What is an abdominal retractor used for?

It holds the abdominal wound open during open surgery so the team can work in the peritoneal cavity with both hands free.

What is the difference between Balfour and Gosset retractors?

Both are self-retaining abdominal patterns, but they differ in frame and blade arrangement. Ask your surgeons which one they prefer.

Do I need a centre blade?

A centre blade is often useful for lower abdominal exposure, but it is optional and can be ordered with the frame.

How do I check if a retractor frame is safe?

Check that the rack teeth lock firmly, blades do not flex, and the frame does not slip under load.
