Surgical Retractors: Types and Sourcing Considerations
Retractors hold tissue or wound edges apart to expose the operating field. They range from simple handheld blades to self-retaining frames and table-mounted systems, and they vary more in size and geometry than most instrument families. This guide explains the main types and the dimensions that make a retractor specification complete.
This guide covers instrument design, specification and sourcing. It is not clinical guidance; instrument selection for a procedure is a decision for qualified clinicians, and care and reprocessing should follow the manufacturer’s instructions for use.
Handheld retractors
Handheld retractors are held in position by a member of the team. They are simple instruments, but blade shape, width and depth vary widely:
- Army-Navy: double-ended, with a different-sized blade at each end.
- Senn: double-ended, with a blade at one end and a rake of three prongs at the other, sharp or blunt.
- Richardson: a single, deeper blade on a handle, made in several blade sizes.
- Deaver: a broad, curved blade for deeper exposure.
- Langenbeck: a right-angled blade on a handle.
- Rake retractors: several prongs on a handle, sharp or blunt.
- Malleable or ribbon retractors: flat strips that can be bent to shape.
Self-retaining retractors
Self-retaining retractors hold themselves open once positioned, using a ratchet, screw or frame:
- Weitlaner: ring handles, a ratchet and rake-style prongs, sharp or blunt.
- Gelpi: ring handles, a ratchet and single pointed tips.
- Balfour: a frame-type abdominal retractor with side blades and a centre blade.
- Table-mounted systems: blades attached to a holding arm or frame fixed to the operating table.
Design differences that matter
- Blade width and depth: the two dimensions that most often separate one size from the next.
- Prongs: number of prongs, and whether they are sharp or blunt.
- Overall length: affects reach and handling.
- Spread: for self-retaining types, the maximum opening.
- Mechanism: ratchet, screw or frame lock, and how smoothly it adjusts and releases.
- Components: for frame systems, which blades and parts are included, and whether parts are sold separately.
Material and finish
Retractors are made from stainless steel. Rigid blades and ratchet parts are typically hardened martensitic grades, while malleable retractors and some blades use softer, more ductile steel so they can be bent and keep their corrosion resistance. Finishes are usually satin (matte), which reduces glare on large blade surfaces, or polished. The grade should be stated per instrument; see the stainless steel guide for background.
Quality checks
- Blades are smooth, with rounded edges where the design requires them and no sharp burrs
- Prongs are aligned, evenly spaced and undamaged
- Welds and joints between blade and handle are clean and secure
- Ratchets and screws engage, hold and release smoothly
- Frame components fit together correctly and the set is complete
- Finish is uniform and free of pits and tool marks

Sourcing and quotation considerations
Retractor names alone rarely define a product. Two suppliers’ “Richardson retractor” can have different blade sizes, so include blade width and depth, overall length and prong details in your request, or quote a catalog code. For self-retaining and frame systems, list the components you need and ask the supplier to confirm what is included in each quoted item.
Larger retractors and frame systems also affect packaging and freight. Ask how they are protected and packed, and include them when you compare air and sea freight. Our RFQ checklist covers how to compare quotations like for like.
