Introducing the iMoc Baroc

Unique mobile operating table for bariatric surgery

From unergonomic working conditions during operations to time-consuming, arduous patient transport: bariatric surgery involves a number of challenges for surgeons and back-up staff. Dockx Medical, working in cooperation with a group of Dutch bariatric surgeons, has developed a mobile operating table that makes life a lot easier. The iMoc Baroc is easy to use and offers optimal ergonomics for doctor and patient together with much faster workflow.

Edo Aarts PhD, surgical resident at Rijnstate Hospital and member of the bariatric team led by Ignace Janssen PhD: “All in all we save 72 minutes a day in the OR.”

Rijnstate Hospital in Arnhem is the biggest centre for bariatric surgery in the Netherlands, performing 1,200 procedures (mainly gastric bypasses) a year. Five years ago, its bariatric surgeons decided to look for an ergonomically optimized alternative to existing operating tables. They got in touch with Dockx Medical, which specializes in mobile operating tables. “It was quite soon clear that it would be a good idea to develop a completely new operating table”, said surgical resident Edo Aarts, also a member of the bariatric team led by Ignace Janssen PhD.

The fruit of this joint venture is the Baroc – a combined wheelchair and mobile operating table, designed for patients weighing up to 350 kg. Various prototypes have been exhaustively tested and improved at Rijnstate Hospital. With excellent results, according to Aarts: “Using the Baroc, patients can sit down in the chair themselves while still on the ward. This eliminates the need for transferring and lifting the patient. An electric motor and a centrally mounted, steerable wheel allows the chair to be moved to the OR with minimum effort.”

The Baroc’s impact on the surgery workflow is substantial, said Aarts. “The mobility of the table means that many of the preparatory activities can be performed outside the OR and that the patient can be wheeled to the recovery room right after the operation. The recovery process can also be speeded up by the fact that the Baroc can be converted back into a chair immediately after the operations. All in all, we save 72 minutes a day in the OR. You could treat another patient every day in that time.”

Once in the operating theatre, the chair can be brought into the recumbent configuration required for the operation by a single push on the button. The best working height and configuration for each surgeon can be pre-programmed.

Crucially, the Baroc’s design creates extra space between the patient’s legs (see Fig. 1). Aarts: “It allows the surgeon to stand 12 centimetres closer to the patient than with traditional bariatric operating tables. That makes all the difference between an upright and a bent-over posture for the surgeon.”

The other members of the surgical team also stand to benefit. Aarts: “The detachable headrests can be removed in operations on smaller patients, allowing the anaesthetists to work in an upright position. The removable side rails give nurses easy access when taking blood samples and inserting infusion lines. Besides, the Baroc is much easier to clean, and hence more hygienic, because all its compartments are sealed off.”

Careful consideration was also given to patient comfort and well-being. “Extensive measurements showed that the Baroc has a much better pressure distribution than the most widely used bariatric operating table, with fewer pressure points and better blood circulation (see Fig. 2). That reduces the risk of pressure ulcers. It also relieves pressure on the calves, which is important in reducing the risk of deep vein thrombosis.”
