Hybrid operating room lights: collision zones, reach and X-ray shields

Why hybrid ORs are different for lighting

A hybrid OR combines a full operating room with high-end imaging, such as a fixed C-arm or angiography system. The imaging equipment moves through large arcs around the table and often occupies ceiling space with rails or a ceiling-mounted stand. Lights, pendants and monitor arms must be positioned around that motion.

You should therefore plan lighting together with the imaging vendor from the first design meeting rather than after the imaging layout is frozen. The questions to resolve are which imaging positions are needed, where the gantry parks and where the lights park.

Mapping collision zones

Ask the imaging supplier for the swept volume of the gantry or C-arm in all required angulations, and overlay it on the ceiling plan together with the light arm lengths and rotation radii. Mark zones where a light head at working height would hit equipment, and mark parking positions outside the imaging sweep.

Check that lights can still reach over the table when the imaging system is at its working position, and that they can be pushed out of the way quickly for an emergency imaging run. Include monitors and pendants in the same exercise, as discussed in our guide to planning the OR ceiling as one system.

Suspension reach and arm configuration

Long arms give a wider operating radius, which helps in large hybrid rooms. Sim.FLEX arms reach up to 2,000 mm, and the system is described as suitable for hybrid ORs, with up to four arms per central axis. Sim.FLEX is also modular, so further arms can be added later, even after installation, as set out on the Sim.FLEX page.

Q-Flow suspensions offer SOLO, DUO, TRIO and QUAD ceiling configurations carrying lights and monitors, with 110 mm ceiling tubes on TRIO and QUAD. See the Q-Flow suspension page. Which one fits depends on how many lights and screens you need and how much ceiling area the imaging system leaves free.

X-ray shields and radiation protection

Hybrid rooms need radiation protection for staff, often through ceiling-suspended protective screens that can be swung between the imaging beam and the team. The SPR spring-balanced arm system from MZ Liberec is described as carrying operating and examination lights, cameras, monitors and X-ray protective screens, with SPR 10 supporting up to 28 kg per arm and SPR 11 up to 12 kg per arm. Details are on the SPR product page.

Ask the room's radiation protection specialist to define required shield sizes and masses and confirm the arm's rated load and rotation range. Also verify that shields, lights and monitors do not block each other and that cleaning access is possible.

• Sim.FLEX: arms up to 2,000 mm, up to four per axis, extendable
• Q-Flow: SOLO, DUO, TRIO, QUAD ceiling configurations
• SPR: arms for lights, cameras, monitors and X-ray screens; 28 kg (SPR 10) / 12 kg (SPR 11) per arm

Lighting performance, video and hygiene

Choose lights with good depth illumination and shadow management, because vascular and cardiac cases often involve deep fields, and with high colour rendering so that tissue colour is accurate. Camera-ready lights and monitor holders help route imaging and OR video, as covered in our guide to OR video integration.

Finally, check laminar flow arrangements. The lights, arms and shields all sit in the air stream, so low-turbulence heads and well-parked arms matter.
