Balfour Retractor
The Balfour is a self-retaining abdominal retractor with two lateral blades and a central blade, commonly called the bladder blade in pelvic surgery. The lateral blades spread the incision; the central blade adds a separate retraction direction. The standard frame rests at the wound rather than mounting to the operating table.[1][2]
Design and variants
- Lateral blades and spreading bar: adjust separation of the wound edges and hold the chosen opening.
- Central blade: attaches to the frame; its size and shape determine its reach into the field.
- Fixed or interchangeable side blades: both configurations exist. The improved Pilling model includes interchangeable side blades of different depths.
- Different sizes: pediatric and adult patterns, maximum spread and blade dimensions vary by manufacturer and catalog number.
- Reusable construction: the reviewed Aspen and Aesculap products are reusable; Aesculap lists its product as supplied nonsterile.[1][2][3]
A catalog dimension is a property of that model, not a recommended wound opening. For example, Pilling 165130 is a standard-opening set with interchangeable lateral blades; its maximum spread is approximately 20.5 cm. Select the frame and blade depth for the incision and patient rather than spreading to the device limit.[2]
Role in reconstructive surgery
A Balfour maintains abdominal-wall exposure when a self-retaining frame is wanted without a table-mounted system. Common reconstructive settings include:
- Open bladder and ureteral reconstruction: bladder-neck reconstruction, augmentation cystoplasty, ureteral reimplantation and the abdominal component of diversion, through midline, Pfannenstiel or Gibson incisions. The lateral blades hold the abdominal wall and the central blade retracts the bladder inferiorly.
- Open sacrocolpopexy: abdominal-wall retraction, with the central blade holding the bladder away for promontory exposure.
- Abdominal fistula repair (VVF, RVF, RUF): wall and bladder retraction during peri-fistula dissection.
- Adjunctive hysterectomy and other open gynecologic surgery during pelvic reconstruction, the classic gynecologic application.
- Prosthetic reservoir and pump-pouch placement when abdominal exposure is needed.
- Laparotomy when speed matters: rapid self-retaining exposure without a custom blade configuration.
A Deaver or Richardson supplements the frame when a deeper structure needs a separately directed blade.
Compared with other self-retaining systems
| Retractor | Mounting | Blades | Typical fit |
|---|---|---|---|
| Balfour | Rests at the wound edge | 2 lateral and 1 central | Routine open abdominal and pelvic work; quick setup |
| Bookwalter | Table-mounted ring | Multiple, independently positioned | Long, deep or complex exposures |
| Omni-Tract | Table-mounted rail with arms | Multiple, on articulating arms | Multidirectional retraction |
| Thompson | Table-mounted ring | Multiple, interchangeable | Alternative to a Bookwalter |
| Collins | Rests at the wound edge | Lateral and central | Transverse lower-abdominal incisions |
A Balfour is usually faster to set up than a ring system. A ring system offers more blade variety and depth. Neither is best for every case: the question is whether the blade geometry available can hold the exposure the operation needs.
Practical use
- Inspect the spreading mechanism and blade attachments before placement. Confirm that detachable components are secured.
- Place the lateral blades under direct vision, with contact on the intended wound tissues and no bowel or other structure trapped beneath them.
- Open gradually, using the amount of retraction needed for the current operative step.
- Add and position the central blade for the target exposure. The name “bladder blade” does not mean it must always press directly on the bladder.
- Reassess blade contact and pressure as the dissection progresses. Release or reposition when the exposure is no longer required.
- Release periodically in long cases. Sustained wound-edge tension can compromise perfusion; loosen the frame when full spread is not needed.
- Remove with controlled release of the spreading mechanism and account for detachable blades.
These are general surgical handling principles. The exact locking and blade-fitting steps follow the instrument's supplied instructions.
Limitations and tissue protection
The frame's stability depends on its position at the wound. In a thick, obese or scarred abdominal wall the lateral blades can slip; a table-mounted system such as the Bookwalter holds more reliably. The fixed lateral and central blades also cannot be configured to the depth and angle of a ring system, so the deepest pelvic and retroperitoneal exposures often need one. Excessive spreading or a blade that is too deep can apply pressure to unintended tissues. If the desired view requires escalating force, change blade size, direction or retractor configuration. Blunt blades can still produce compression injury; inspect deep blade tips and the tissue beneath them.
Care and reprocessing
Clean detachable blades and the spreading mechanism as directed for the specific model. Reusable does not mean supplied sterile. Aspen's current reusable-instrument instructions specify cleaning and sterilization before use; the applicable validated cycle depends on the instrument and packaging.[3][4]
Historical note
Donald Church Balfour (1882–1963) described the self-retaining abdominal retractor at the Mayo Clinic in 1912. It belongs to the same Rochester instrument tradition as the Mayo scissors and Mayo-Hegar needle holder. The historical account is background, not evidence of comparative clinical performance.[5]
