The new prototype was tested by a panel of experts and novices during an indicative ergonomic experiment. A major advantage of the MIM seems to be the possibility to perform laparoscopic surgery in a sitting position, in line with the working axis, instead of standing at the side of the patient. At an estimated cost level of 10% of the da Vinci system, the MIM can be an economical alternative for the enhancement of laparoscopy ergonomics. However, further development for clinical feasibility is necessary.
