目的：为了提高乳腺手术的教学效率，研制一种单人乳腺手术教学系统。方法：单人乳腺手术教学系统由磁悬吊牵拉装置和乳房模型组成。磁悬吊牵拉装置由磁悬吊组件与磁牵拉组件组成，其中磁悬吊组件由支架、外磁体与内磁体组成，磁牵拉组件由磁性底座和弹性抓钳组成。乳房模型以屠宰场获得的猪腹部组织为基础构建。将12名外科实习医生随机分为实验组（n=6）和对照组（n=6）,2组以保留皮肤的乳房切除术为目标术式，在乳房模型上进行皮瓣游离操作。其中，实验组使用研制的系统，对照组采用传统手术方法。结果：2组均顺利完成皮瓣游离操作，且2组的切口长度比较差异无统计学意义（P>0.05）；实验组所需的助手人数显著少于对照组，手术时间、皮瓣损伤次数、腺体损伤次数均明显少于对照组，暴露效果显著优于对照组，差异有统计学意义（P均<0.05）。结论：单人乳腺手术教学系统可有效提高暴露效果，能够满足单人训练的要求，提高教学效率。
Abstract：Objective To develop a single-person breast surgery teaching system to improve the teaching efficiency of breast surgery. Methods The single-person breast surgery teaching system consisted of a magnetic suspension and retraction device and a breast model. The magnetic suspension and retraction device was composed of a magnetic suspension component and a magnetic retraction component, of which, the magnetic suspension component included a bracket, an outer magnet and an inner magnet and the magnetic retraction component comprised a magnetic base and an elastic grasping forceps. The breast model was established with porcine abdominal tissue obtained from slaughterhouses. Twelve surgical trainees were randomized into an experimental group(n=6) and a control group(n=6), and the 2 groups performed flap release operations on the breast model with skin-preserving mastectomy as the target procedure. The operation was carried out with the developed system in the experimental group and with the traditional procedure in the control group. Results The two groups had the flap-free operation on the breast model finished successufully, which had no significant differences in the length of incision(P>0.05); the experimental group gained advantages over the control group in the number of assistants required, operation time, times of skin flap injuries, times of glandular injuries and effect of exposure, with the differences being statistically significant(all P<0.05). Conclusion The single-person breast surgery teaching system enhances the effect of exposure efficiently, meets the reequirements for single-person training and improves the teaching efficiency.
