How to Assemble a Bookwalter Retractor
Reviewed by Retractor Maker technical team · Updated
A Bookwalter Retractor is made up of several components that work together to create a stable, table-mounted retraction framework. The exact configuration varies depending on the system and the surgical requirement.
This article gives a general educational overview of how a Bookwalter-style retractor system is put together. It is not a set of official instructions for use. The assembly and use of any specific configuration should follow the manufacturer's instructions supplied with the set, applicable institutional procedures, and the judgement of appropriately trained surgical professionals.
Bookwalter Retractor Components Used for Assembly
Most configurations are built from the same family of components.
- Field Post — mounts to the operating table rail area and supports the retractor framework.
- Horizontal Bar — provides structural support between the post and the framework.
- Horizontal Flex Bar — a bar option that helps with positioning the framework.
- Post Coupler — connects supporting components to each other.
- Retractor Ring — forms the framework around the incision to which retraction mechanisms attach.
- Ratchet Mechanisms — clamp to the ring and hold the blades.
- Retractor Blades — provide the tissue retraction itself.
Individual components can be reviewed on the Bookwalter retractor parts page.
Step-by-Step Bookwalter Retractor Assembly
- Position the Field Post. The field post is secured first because it carries the rest of the framework.
- Attach the supporting bars. The horizontal bar provides structural support, while a horizontal flex bar can be used where additional positioning flexibility is needed.
- Connect the required components. A post coupler is used to join supporting components so the framework holds its position.
- Position the retractor ring. The ring is mounted so that it forms the retraction framework around the operative field.
- Attach the ratchet mechanisms. Ratchets clamp to the ring, provide the attachment points for the blades, and allow positioning adjustments.
- Select and attach the blades. Blades are chosen according to the required configuration and the exposure needed, then fitted into the ratchets.
- Position and adjust the retractor. The assembled system is positioned and adjusted according to the operative requirements.
Configurations differ between systems and procedures, so no single assembly method applies to every set. Follow the documentation supplied with your own system.

Frequently Asked Questions
How do you assemble a Bookwalter Retractor?
In general terms, the field post is positioned first, supporting bars and couplers are connected, the retractor ring is positioned, ratchet mechanisms are attached to the ring, and blades are then fitted and adjusted. The exact steps depend on the configuration and the instructions supplied with the system.
What parts are needed to assemble a Bookwalter Retractor?
Typically a field post, a horizontal bar or horizontal flex bar, a post coupler, a retractor ring, ratchet mechanisms and the required retractor blades.
Where does the Field Post fit?
The field post is secured at the operating table so that it supports the rest of the retractor framework.
What is the purpose of the Post Coupler?
The post coupler connects supporting components of the framework to each other.
How are Bookwalter Retractor blades attached?
Blades are attached through ratchet mechanisms that clamp to the retractor ring and allow the blade position to be adjusted.
Can different Bookwalter configurations be assembled?
Yes. Different rings, supporting components, ratchets and blade sets can be combined depending on the surgical requirement.
