How to Choose a Surgical Pendant for Your Operating Room

What a surgical pendant has to deliver

The pendant is a service point, not a piece of furniture. It carries gas outlets for oxygen, medical air and vacuum, low-voltage and mains sockets, equipotential bonding points and often network connections, and it must hold equipment weight safely while moving smoothly under one hand. Because it hangs over the sterile field area, a pendant also affects airflow, cleaning routine and the positioning of surgical lights, so it should be planned together with the ceiling layout rather than selected last.

Before comparing models, write down the workflow: which specialties use the room, how many devices sit on the pendant at the same time, and whether the team needs a separate anaesthesia pendant. A general theatre, a laparoscopic room and a hybrid theatre place very different demands on reach and load.

Arm reach, rotation and head type

Reach decides whether the service head can be parked where the team needs it without crossing the table. Rotating arms on the MZ Liberec TAURUS range from 450 to 1350 mm and rotate up to 400 degrees with pneumatic brakes or 350 degrees with electromagnetic brakes. OK07 pendants offer arm lengths of 600 to 1000 mm in rigid, rotary and height-adjustable models, and SIMEON Sim.CARRY offers extension arms of 450, 600, 800 and 1000 mm.

Head type matters as much as arm length. The OK07 family, for example, uses a horizontal head A for anaesthesia, a vertical head L for surgery, a head Z with a holder for the anaesthesia machine and a square head H with shelves on four sides. Match the head to the clinical task instead of buying one universal configuration.

Load capacity, shelves and mounted equipment

Ask for the permitted load of the arm at the actual arm length, not only a headline figure. TAURUS, for instance, lists up to 500 kg for a single 850 mm arm and 320 kg for a double 850 plus 850 mm arrangement, with shelves of up to 60 kg on a four-sided rail. Total the weight of monitors, insufflators, ventilators or camera towers that will really be placed there, and keep a margin.

Large displays are now common. The OK07 family has a holder for 32 to 60 inch screens for hybrid and multidisciplinary theatres, which is worth checking against the ceiling structure. Confirm what the building can carry and who is responsible for the structural calculation before the first fix.

Outlets, brakes and hygiene

Count outlets per gas and per voltage, and confirm the connector standard used in your hospital, since gas couplings differ by national standard. MZ Liberec builds outlets to standards such as DIN, AFNOR and BS, and Sim.CARRY supports common international standards with adapters for common anaesthesia machines. Where a pendant carries mains sockets, check the rating: the Lojer Solido pendants list 100 to 230 VAC, up to 2000 W per socket and a noise level below 35 dB in the operating room.

Brakes should hold the arm in place without drift and release without effort. Solido uses a brake system with indicator lighting, and TAURUS adds a passive friction brake in each swivel joint. For hygiene, prefer slim profiles with rounded corners and no visible fixing screws, which wipe down faster and trap less soil.

Questions to ask a supplier

A good supplier can answer technical questions in writing and support the project after delivery. Compare offers on the same specification, and ask for drawings that show the pendant in relation to the lights, the table and the air-handling diffusers. See also our guide on how arm configurations differ before you fix the layout.

• Which standard governs the design, and is a type test or conformity declaration available for the exact configuration?
• What is the permitted load at each arm length and rotation limit?
• Which gas connectors and socket types are included, and can they be changed later?
• Is the pendant built to order, and what is the lead time for the specified colours and heads?
• Who handles installation, commissioning and maintenance in the UAE?
