Abstract
Background. The laparoscopic surgeon requires very fine motor dexterity to perform complex surgical procedures. This skill can be significantly altered by the motor stress of the surgeon, which mainly results from a lack of ergonomics of the instruments. The objective of this article was to analyse a new ergonomic system that can significantly reduce motor stress. Material and Methods. Two expert surgeons tested the new ergonomic system by performing transfer and suture tasks. The results were compared to those obtained from executing the same tasks using commercial laparoscopic instruments, without any pre-selection being established. Electronic switches were placed on the handles of the instruments to register the time of opening and closure, as well as the time taken to complete the tasks. Results. The comparative data indicate that the new ergonomic system substantially reduces the motor stress of the surgeon by reducing the number of manual operations needed to carry out the routine training tasks of transfer and suture. Conclusions. A new ergonomic system has been developed that reduces the number of manual operations required for carrying out the same task using commercial laparoscopic instruments. The execution time and motor stress is substantially decreased with this new design. We have confidence that these results will be extended to surgical procedures.
