4.1 Handheld Retractors
Key Takeaways
- Army-Navy is the double-ended right-angled blade retractor of unequal blade depths; Richardson has a single deeper right-angled blade with a hollow grip.
- Deaver is a long, flat, curved single-blade retractor sized by blade width for deep abdominal exposure.
- Senn is a double-ended retractor with three sharp or blunt prongs on one end and a flat blade on the other.
- Malleable ribbon retractors are 300-series steel intended to be hand-bent, and repeated bending eventually work-hardens and cracks them.
- Sharp rake retractors are identified by prong count and by whether the prongs are sharp or blunt, and every prong is inspected for straightness and point condition.
The Handheld Family
A handheld retractor is held by an assistant. It has no ratchet and no locking frame; identification rests on blade shape, blade depth, prong count, and whether it is single- or double-ended.
| Retractor | Form | Where used |
|---|---|---|
| Army-Navy (USA) | Double-ended, right-angled blades of two different depths | Shallow to moderate incisions — the universal general retractor |
| Richardson ("Rich") | Single-ended, deeper right-angled blade, hollow or solid grip | Abdominal wall retraction |
| Richardson-Eastman | Double-ended Richardson | Two depths in one instrument |
| Deaver | Long, flat, curved single blade, sized by width (½ in to 3 in) | Deep abdominal, liver, gallbladder |
| Kelly / Harrington ("sweetheart") | Broad blade; Harrington has a heart-shaped end | Liver and deep viscera |
| Senn (Senn-Miller) | Double-ended: 3 prongs (sharp or blunt) on one end, small flat blade on the other | Superficial, plastics, hand, thyroid |
| Volkmann rake | 1–6 prongs, sharp or blunt | Superficial retraction |
| Skin hooks (Joseph, Guthrie) | Single or double fine sharp hooks | Plastics, skin edges |
| Malleable / ribbon | Flat, soft, hand-bendable strip | Any cavity; bent to fit |
| Vein / Cushing vein retractor | Small right-angle blade | Vessels, nerves, delicate structures |
| Parker | Double-ended, two shallow blades of equal size | General, superficial |
| Parker-Mott | Double-ended Parker with dissimilar blades | General |
| Goelet | Double-ended, right-angle blades | General |
Army-Navy vs Parker is a common trap: both are double-ended blade retractors of similar overall length, but the Army-Navy carries two right-angled blades of unequal depth, letting one instrument serve two exposure depths, while the standard Parker carries two shallow blades of equal size. The Parker-Mott variant is the one with dissimilar blades, which is exactly why the modifier on the count sheet matters.
Deaver Sizing
A Deaver is specified by blade width, and count sheets list them by size ("Deaver 1 inch", "Deaver 2 inch"). The blades are otherwise identical in shape, so an assembler must read the width. Deaver sets stored together on a rack are a common source of "complete count, wrong set" errors when the widths are not verified.
Malleable Retractors — a Special Case
Malleables (ribbon retractors, brain spoons, malleable blades) are made of soft, non-hardenable 300-series stainless precisely so they can be bent by hand at the field. Two consequences:
- They arrive bent and must be straightened before packaging, or they will not fit the tray and will bend other instruments.
- Repeated bending work-hardens the metal. A malleable that has become stiff, that shows a whitish stress line at a repeated bend point, or that has a visible crack is at the end of its life and must be removed. A malleable that cracks intraoperatively is a retained-fragment event.
Malleables are also commonly colour-coded by width with dipped ends or bands, which links them to the marking sub-topic in Chapter 8.
Prong Retractors
Senn retractors, Volkmann rakes, and skin hooks are identified by prong count and by sharp or blunt:
- "Senn, sharp" and "Senn, blunt" are different line items on a count sheet.
- "Volkmann rake, 4-prong, blunt" specifies both.
- Skin hooks are specified as single, double, or by eponym (Joseph, Guthrie, Frazier).
Inspection is prong-by-prong: each prong must be straight, in the same plane, of equal length, and sharp prongs must have an intact point. A bent prong tears tissue and a broken prong is a foreign body.
Inspecting Handheld Retractors
| Check | Why |
|---|---|
| Blade flatness and straightness | A twisted blade slips off tissue and concentrates pressure |
| Edges and corners smooth | Burred or sharp edges lacerate; retractor edges are meant to be rounded |
| Handle-to-blade junction | Welded or brazed joints crack under leverage; check for a hairline at the junction |
| Surface | Pitting, cracks, and chipped plating |
| Size markings legible | The OR must be able to confirm the requested width |
| Malleables: straightened, uncracked, still pliable | Work hardening is progressive and predictable |
| Prongs: count, plane, length, point | Bent or broken prongs injure and can fragment |
Retractors carry high leverage loads, which is why the junction between the working blade and the handle deserves specific attention. Deavers and Richardsons that have been used as levers develop hairline cracks there long before anything visible happens to the blade.
Blade Geometry Tells You the Depth and the Tissue
Handheld retractors are identified almost entirely by the shape of the working end, and each shape encodes the job it was designed for.
A flat, smooth, wide blade — Deaver, Richardson, Harrington — spreads force over a large surface and is used on organs and deep abdominal walls. A hooked or right-angled blade such as the Richardson catches and holds a wound edge at a defined depth. The Harrington ends in a broad, spoon-shaped, heart-like blade specifically to cradle the liver, which is why it is often called a sweetheart retractor. The Kelly and Parker are double- or single-ended flat blades for moderate depth. A rake or prong end — Senn, Volkmann, Army-Navy at the shallow end — engages superficial tissue directly, and the prongs may be sharp or blunt, which is a separate line on the count sheet.
The Army-Navy deserves special attention because it is double-ended with two different blade depths on one instrument, making it the general-purpose superficial retractor found on almost every major set.
Beyond the Common Names
Several named handhelds appear on specialty sheets and are worth recognising. The Ribbon (malleable) retractor is a plain flexible strip of 300-series stainless with no handle, supplied in graduated widths. The Goelet is a double-ended right-angle retractor. The Cushing vein retractor is a small, delicate right-angle used in neurosurgery. The Meyerding is a finger-held rake used in spine and orthopaedic work. Skin hooks — Joseph, Guthrie, Frazier — carry one, two, or more fine sharp points for plastic and facial work and are processed as sharps.
Inspection Priorities Unique to Handhelds
Handheld retractors have no hinge, no ratchet, and no lumen, so inspection concentrates on three things.
Blade edges must be smooth and free of burrs, nicks, and cracks. Run a gloved finger along the edge or draw it across a gauze pad; a burr that snags gauze will snag tissue or a glove. Surface integrity matters because these are large flat surfaces that show pitting and staining early. Shape must be correct — a blade bent out of its designed curve, or a malleable that has been folded so sharply that it has creased or cracked, cannot be simply bent back into service without inspecting the crease for fracture.
Because handhelds are heavy, they are also the instruments most likely to damage others. Place them at the bottom of the tray, never on top of delicate items, and count their weight into the total tray mass when configuring the set.
