目的：通过取出猪体内异物测试单电极金属异物探测器的实用性。
方法：根据互补振荡器原理，研制单电极金属异物探测器。取3只明尼苏达-荷曼系7月龄成年雄性猪，处死后取肢体共12具，根据打入金属异物不同，分为3组，A组为块状金属异物，B组为针状金属异物，C组为沙粒样金属异物。应用自制探测器探测异物位置，取出并计时，术后即刻复查X线片检测异物取出情况。
结果：3组异物均完整取出，平均用时分别为38 s、3 min 12 s和3 min 59 s。术后X线片显示异物无存留，此探测器均成功取出异物。
结论：此探测器在动物实验中效果满意，可在术中无须X线机辅助的条件下快速准确定位，取出金属异物，可进一步应用于临床。 |

| Experimental study on single-electrode metal detector for taking off foreign bodies from the swine |
|
Abstract:
Objective: To study the practicability of single-electrode metal detector by using it to take off foreign bodies from swine.
Methods: The single-electrode metal detector was invented based on the theory of complementary oscillator. Twelve extremities were obtained from 3 Minnesota-Hormel stains 7-month old male swine. All the extremities were divided into 3 groups:lump metal foreign bodies were planted in group A,needle shape metal foreign bodies were planted in group B,and sand shapd metal foreign bodies were planted in group C. The self-invented single-electrode metal detector was used to take off these foreign bodies,and the taking times were recorded. After the operation,the X-ray was used to examine if the foreign bodies were still in the extremities of the swine.
Results: The foreign bodies were taken off completely in the 3 groups,and the average time were 38 s,3 min and 12 s,and 3 min and 59 s respectively. The X-ray examination confirmed that the detector could take off the foreign bodies completely.
Conclusion: This detector has satisfactory effect in animal experiment,which could detect and extract metal foreign bodies quickly and exactly without X-ray help duration the operation,and can be used in clinical cases secondly. |
