Background: Robotic equipment can greatly add to the ergonomics of a surgical procedure and pre-operative simulation can provide risk-free training of the surgeon leading to precision surgery and less trauma to the patient. FreehandVR is a second-generation robotic camera-holding device, which has recently become available to laparoscopic surgeons. It is controlled by the operator selecting a direction using head movement followed by activation with a foot pedal. The purpose of this study was to assess the rate of skill acquisition in the use of the FreeHandVR robotic laparoscope holder by a group of laparoscopic surgeons by enrolling them into a programme of training modules at The ICENI Centre, Colchester Hospital University, UK. Material and methods: Twenty surgical registrars performed a series of exercises, escalating in difficulty, to test their skill in controlling the FreeHandVR robot. Subjective and objective assessments were evaluated by an observer and by tracking analysis software created for this trial. Results: The observed number of head movements showed a Percentage Performance Score (PPS) of 98% by the end of the third repetition of all exercises, the mean Total Head Movements Score (HMS) reached a plateau of performance at 72%. Fifty per cent of the participants selected ‘Effective control of movements without difficulty’ in the subjective evaluation by the end of the third repetition of exercises, while 35% selected ‘competent intuitive movements’. Conclusion: The FreeHandVR robotic laparoscope holder is a useful device, which is easy to operate and requires a very short course of training to achieve competence in its use.
