【摘要】： 目的：建立2μm激光离体动物组织操作培训模型,并对应用该模型进行操作技能培训进行评价。对象与方法：解冻的冰冻离体猪心脏被固定在离体动物组织培训模型培训箱内。无2μm激光操作经验的低年资外科医师10名,分2阶段接受使用2μm激光前列腺切割汽化操作镜,在离体动物组织模型中进行对猪心肌腱索切割和汽化操作技术培训并分别记录操作时间。期间应用生理盐水冲洗以保持术野清晰。第1阶段前对受训者进行猪心脏解剖、离体动物组织模型中进行切割和汽化操作要求的讲解,第2阶段前对受训者进行2μm激光相关理论和操作培训。分析比较2阶段基本技术操作时间变化。结果：应用冰冻离体猪心脏建立2μm激光离体动物组织培训模型经济、可行。受训者对离体动物组织培训模型接受良好。操作空间大小类似应用激光治疗BPH时前列腺尿道部的空间,足够进行激光操作培训。2阶段培训顺利进行,无危险性意外事件发生。10名受训者中2名缺席第2轮操作,共收集到8组数据。8名受训者第1阶段切割时间、汽化时间以及总操作时间分别为166±94s,224±81s,390±145s；接受培训后的第2阶段切割时间、汽化时间以及总操作时间分别为75±28s,105±28s,180±46s。2阶段比较差异均有统计学意义(P0.01)。结论：建立2μm激光离体动物组织操作培训模型进行相关技术培训可行。接受理论与操作指导并应用本模型培训可以显著提高受训者基本操作技术如切割和汽化。
[Abstract]:Objective: A 2 渭 m laser in vitro animal tissue training model was established, and the application of the model to the training of operation skills was evaluated. Objects and methods: Thawed frozen isolated pig hearts were fixed in an in vitro animal tissue training model training kit. Ten young surgeons without 2 渭 m laser operating experience were treated with 2 渭 m laser vaporization operation mirror in 2 stages. In vitro animal tissue model, the pig cardiac tendon cord cutting and vaporization techniques were trained and the operation time was recorded. Use saline to keep the surgical field clear. In the first stage, the pig heart was dissected, and the requirements of cutting and vaporizing were explained in the animal tissue model in vitro. In the second stage, the trainees were trained in the related theory and operation of 2 渭 m laser. Analyze and compare the change of operation time of basic technology in two stages. Results: Using frozen isolated pig heart to establish 2 渭 m laser in vitro animal tissue training model is economical and feasible. The trainees received good training models of in vitro animal tissues. The size of the operation space was similar to that of the urethral part of the prostate treated with laser, which was sufficient for the training of laser operation. 2 out of 10 trainees were absent from the second round operation. A total of 8 groups of data were collected. The cutting time, vaporization time and total operating time of the first stage of 8 groups of trainees were 166 卤94s, 224 卤81s, 390 卤145s, respectively. The vaporization time and the total operating time were 75 卤28sL, 105 卤28sL and 180 卤46s.2, respectively. The difference was statistically significant (P 0.01). Conclusion: The establishment of 2 渭 m laser in vitro animal tissue training model is feasible. Receiving theoretical and operational guidance and applying this model can significantly improve the basic operating techniques such as cutting and vaporization.
