Surgical retractors: hand-held, self-retaining and frame types

What is a retractor in surgery?

A retractor is a tool that separates the edges of a wound or pulls back an organ, muscle or other structure to expose the area beneath. Without good retraction, even a skilled surgeon works in a narrow, poorly lit space. Retractors are therefore among the most used instruments in any theatre.

They are classified by how they are held. Hand-held retractors need an assistant. Self-retaining retractors lock open on their own, freeing the assistant's hands. Frame retractors attach to the table or a ring and hold a large exposure, typically in abdominal or chest surgery.

In practice a general surgery set usually contains a mix of all three: a few hand-held retractors in different widths for the assistant, one or two self-retaining retractors for short cases, and a frame system when the department performs open abdominal procedures. Planning the mix from your case list avoids both shortages and unused instruments.

Hand-held retractors: types and names

The REDA range lists Langenbeck, Farabeuf, Kocher and Volkmann hand retractors, as well as Deaver, Kelly and Richardson retractors, malleable ribbon retractors, Cushing nerve retractors and fine hooks. Langenbeck and Farabeuf retractors are the everyday choices for superficial wounds, Deaver and Richardson reach deeper cavities, and ribbon retractors can be bent to shape and used to protect organs.

Blade width and depth matter more than the pattern name: a wide, shallow blade suits a skin incision, while a long, curved blade suits a deep abdominal wound. For more detail see hand-held retractors such as Langenbeck and Farabeuf.

• Langenbeck, Farabeuf: superficial wounds
• Deaver, Richardson: deeper cavities
• Malleable ribbon: shaped to protect organs
• Cushing nerve retractors and fine hooks: delicate work

Self-retaining surgical retractors

Self-retaining designs include Weitlaner and Gelpi retractors, with a ratchet and sharp or blunt prongs that grip the wound edges. Weitlaner is used for soft tissue and orthopaedic exposures, and Gelpi, with its pointed tips, for deeper, narrower wounds such as in spinal surgery. Blunt versions reduce the risk of tissue injury where sharp prongs are not appropriate.

When you buy these, check the strength of the ratchet, the alignment of the prongs and the smoothness of the screw or rack mechanism. A ratchet that slips during a case is both annoying and unsafe. See our article on self-retaining retractors for a closer comparison.

Frame and specialty retractors

For abdominal surgery, the range includes Balfour and Kirschner abdominal retractors, which hold the incision open with side blades and a centre blade attached to a frame. They are commonly used for laparotomy. The article on abdominal retractors, Balfour and Kirschner describes their use.

For spinal procedures there is the Caspar system: retractors with interchangeable blades, distractors and lumbar vertebral specula. Fenestrated titanium blades are also listed. Rib spreaders are a different frame type used in thoracic surgery and have their own article on the Finochietto rib spreader.

Check also how blades attach to the frame, whether they are interchangeable and what lengths are available, since deep exposure in a large patient needs different blades than a thin patient. Replacement blades should be easy to source separately.

Specifying and buying retractors

To specify a retractor correctly, give the pattern name, blade width and depth, overall length and whether it is sharp or blunt, single or double ended. Surgical retractor names are not always standardised between manufacturers, so ask for the catalogue code to avoid ambiguity. You can browse the full REDA retractors section for the patterns listed.

Counts matter for infection control: retractors with ratchets and screws are harder to clean, so confirm that they can be disassembled where required and that the reprocessing instructions are supplied.

A final point is handling: retractors that are pulled too hard or left in place for a long time can compress tissue, nerves and vessels. Teams should be trained to release tension periodically, and instrument design with smooth edges and well-sized blades helps limit the risk.
