The new Trimano 3D arm support acts as a “third
hand” for all surgeons: It positions the arm of the
patient in orthopaedic and traumatology operations.
Rastatt/Germany, August 2010. With the new Trimano
3D support arm, Maquet, the workflow specialists, are
able to further expand their already extensive product
portfolio in the field of assist systems and OR
accessories. The assist system is deployed as a “third
hand” for the surgeon, in orthopaedics and traumatology.
It has been specially developed for operations to the
shoulder and upper arm area.
Trimano improves the workflow
The support arm includes a sterile arm rest and adapter
and is used to locate and hold the patient’s arm securely
in the required position throughout the operation. The
unrestricted manoeuvrability of the Trimano, rapid and
accurate repositioning can be carried out at any time
during the operation. The patient’s arm can also be lifted
off the support and moved freely, in order to monitor the

results of the operation. “Deploying the support arm
brings about a significant improvement in the work
process. Thanks to the secure, fixed site of the
operation, the work can be completed more easily and it
takes less time, allowing us to concentrate 100% on our
core tasks”, commented Dr. Stefan Studier-Fischer,
Senior Physician in the Department for Shoulder and
Elbow Surgery at the Berufsgenossenschaftlichen
Unfallklinik in Ludwigshafen. “It also means that the
Assistant Physician, who would normally hold the
patient’s arm and move it to the required positions during
the operation, can take on more demanding tasks”. With
smaller-scale operations, the support arm allows the
surgeon to be able to compensate for any staff shortages
more effectively.
The initial preparation for the positioning of the patient’s
arm can be made in the induction room. The arm is
positioned on the support arm and an arm pad.
Then, in the operating theatre, the patient’s arm is simply
transferred from the arm pad onto the sterile arm rest. An
adapter that was developed in parallel, makes it easy to
mount the arm rest into place. It connects the arm rest
with the support arm resulting in greater handling and

control for the user. Being able to optimise changeover
times by preparing the patient in advance, contributes to
the more efficient utilisation of OR capacity and
increases patient throughput accordingly.
Increased ergonomics and safety
An ergonomic body posture and a stable position are
essential basics for the surgical team and both of these
requirements are fulfilled by the deployment of the
Trimano support arm. A contributing factor is that the
device can be operated independently of power and
compressed air. Therefore no allowances have to be
made for cable or hose connections. Fast and safe
intraoperative modification of the arm position is made
thanks to the “Click and Move” locking mechanism.
Deployment of the support arm provides an additional
benefit in respect of radiation hygiene: Due of the
pinpoint accuracy of the arm positioning, the assistant
can move out of the area exposed to X-ray radiation.
An assist system for all OR tables
The Trimano 3D support arm can simply be fixed to the
OR table’s accessory rail. As well as using it with Maquet
OR tables, this also means that it can be used with OR

tables from other manufacturers, giving the hospital more
flexible deployment options.
