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. Freehand(®) 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 FreeHand(®) 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.
Twenty surgical registrars performed a series of exercises, escalating in difficulty, to test their skill in controlling the FreeHand(®) robot. Subjective and objective assessments were evaluated by an observer and by tracking analysis software created for this trial.
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'.
The FreeHand(®) 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.
机器人设备可极大地改善外科手术的人体工程学，术前模拟可为外科医生提供无风险培训，从而实现精准手术并减少对患者的创伤。Freehand（®）是第二代机器人持镜设备，最近已可供腹腔镜外科医生使用。它由操作员通过头部移动选择方向，然后用脚踏板激活来控制。本研究的目的是通过让一组腹腔镜外科医生参加英国科尔切斯特大学医院ICENI中心的培训模块计划，评估他们使用FreeHand（®）机器人腹腔镜持镜器的技能获取率。
20名外科住院医师进行了一系列难度逐渐增加的练习，以测试他们控制FreeHand（®）机器人的技能。由一名观察者以及为本试验创建的跟踪分析软件对主观和客观评估进行评价。
在所有练习第三次重复结束时，观察到的头部移动次数显示出98%的表现百分比得分（PPS），平均总头部移动得分（HMS）在72%时达到性能平稳期。在练习第三次重复结束时，50%的参与者在主观评估中选择“轻松有效控制动作”，而35%选择“熟练的直观动作”。
FreeHand（®）机器人腹腔镜持镜器是一种有用的设备，易于操作，只需非常短的培训课程就能掌握其使用方法。
