How to Choose a Laparoscopic Instrument Trolley

What the trolley has to carry

List every device that will sit on the cart before you look at models. A typical laparoscopy tower combines a medical monitor, camera controller, light source, insufflator, suction and irrigation pump, an electrosurgical unit and sometimes a video recorder or ICG module. Add the weight of each device from the manufacturer's data sheet, then add a margin for future additions such as a second monitor or a recorder.

Check the load limit per shelf as well as the total. A cart rated for a high total load can still fail if a heavy generator sits on a lightly rated shelf. Ask the supplier for the shelf rating, the permitted monitor weight on the arm and the cart's tilt stability when it is pushed over a threshold or floor joint.

• Total and per-shelf load rating
• Monitor weight and screen size
• Number and height of shelves
• Space for future modules

Shelf layout, monitor arm and ergonomics

Shelves should be height-adjustable and large enough for the devices without overhanging, so that ventilation openings are not blocked. Place heavy equipment low, put the camera controller where the nurse can see its status, and keep the insufflator and pump display visible from the circulating position.

The monitor should sit at or slightly below eye level for the surgeon and be adjustable by tilt, swivel and height. A rigid arm with a good locking mechanism avoids drift during long cases. For details of the monitor itself see our guide to the surgical monitor for endoscopy.

Power, grounding and cable management

Medical carts should provide an isolated power distribution with a single mains lead to the wall, appropriate earthing and leakage-current limits according to IEC 60601-1. Confirm with your biomedical engineers whether the cart is supplied as a medical electrical system and who is responsible for the system-level test after installation.

Cable management is more than appearance. Integrated cable channels, strain relief and holders for light cables and camera cables reduce trip hazards and prevent damage to expensive fibre-optic cables. Check that the cart has enough sockets and a mains lead length that reaches ceiling pendants or wall outlets in your theatres.

Mobility and infection control

Look for large, smooth-rolling castors with a brake on at least two wheels, ideally a central locking system. Test the cart on your own floors, including joints and ramps. Handles must be positioned so that a single nurse can steer it without pulling on cables.

Choose surfaces that withstand your cleaning agents: powder-coated steel, anodised aluminium or stainless steel are common, and open shelves without difficult corners are easier to wipe. Check that all fastenings are accessible, so that dust and fluids do not collect.

Integration with your endoscopy tower and procurement

Buying the cart separately from the devices often saves time, but make sure the equipment you already own fits mechanically and electrically. Our overview of endoscopy tower components shows the modules that normally sit on the cart, and the laparoscopic tower buying guide explains how to compare complete packages.

When you write a tender, add the cart as a separate line with dimensions, load rating and standards. See also our endoscopy tender specification checklist. Beckfinity can advise on trolleys and complete laparoscopy configurations; reach us through the contact page.
