Atraumatic soft issue handling is essential for optimal wound healing. Simulation is a safe and effective way to improve surgical skills outside the operating room. Our primary aim was the development of a pressure-sensing forceps that measures the force applied to a given tissue and provides real-time biofeedback. Seventy-eight students and trainees performed four trials of a continuous subcuticular closure using our Tissue Handling Trainer System device on a silicone skin model. We recorded the occurrence of above-threshold pressure and duration of time over the threshold. A one-way analysis of variance with Tukey post hoc test was used to analyze duration above-threshold pressure. There were statistically significant differences in the duration above threshold from trials 1 to 3 ( < 0.001). A 36% reduction occurred between trials 1 and 2 after participants learned of the study purpose, but a 70% reduction between trials 2 and 3 with audible feedback. There was no statistically significant difference between trials 3 and 4 ( = 0.807). The Tissue Handling Trainer System may be an effective technique for improving tissue handling skills in the surgical simulation laboratory.
无创软组织处理对于实现最佳伤口愈合至关重要。模拟是在手术室之外提高手术技能的一种安全有效的方法。我们的主要目标是开发一种压力传感镊子，该镊子可测量施加于特定组织的力并提供实时生物反馈。七十八名学生和学员使用我们的组织处理训练系统设备在硅胶皮肤模型上进行了连续皮下缝合的四项试验。我们记录了超阈值压力的发生情况以及超过阈值的持续时间。使用带有Tukey事后检验的单因素方差分析来分析超阈值压力的持续时间。试验1至3之间超阈值压力的持续时间存在统计学显著差异（<0.001）。在参与者了解研究目的后，试验1和2之间减少了36%，但在有听觉反馈的情况下，试验2和3之间减少了70%。试验3和4之间没有统计学显著差异（=0.807）。组织处理训练系统可能是在手术模拟实验室中提高组织处理技能的一种有效技术。
