仿真外科训练系统在微创外科的应用

Virtual reality training in minimally invasive surgery

目的 通过比较计算机模拟仿真训练和传统训练模型的训练效果,对模拟仿真训练的有效性和可行性进行评价。方法 17名低年外科医生和24名医学生被随机分成4组,分别受到计算机模拟仿真训练或传统训练模型的训练1 h。在接受训练后,他们将在传统训练模型中接受连续缝合测试30 min,根据完成缝合的数量和准确性来评价被测试者的能力。结果 无论接受何种训练,低年外科医生的测试结果都优于医学生,尤其在缝合速度方面。无论低年外科医生还是医学生,接受计算机模拟仿真训练的测试结果优于传统训练。结论 计算机模拟仿真训练将可能在腹腔镜外科训练中发挥重要作用。

Objective To evaluate the training benefits of computer simulation compared with conventional training modalities for minimally invasive surgery. Methods Seventeen junior surgeons and twenty - four medical students were randomized into four groups . They practiced with either a conventional laparo-scopic training model or a Virtual reality(VR) simulator for one hour. After the practice session, each participant performed running sutures with a conventional laparoscopic training model for half an hour. The number of completed stitches and the average accuracy of each stitch were measured to assess the skills acquired in practice. Results Regardless of the kind of training, junior surgeons performed better than medical students, especially in suture speed. Both medical students and junior surgeons trained with VR tended to have better scores than those who underwent training with a conventional laparoscopic training model. Conclusion Virtual reality training could make a major contribution to training in laparoscopic surgery but further studies will be needed to confirm these preliminary findings.
