本文介绍了自行研制的一种低频脉冲电磁场颌骨愈合仪，该仪大小为１１．２ｃｍ×７．４ｃｍ×３．６ｃｍ，利用特制的可塑形治疗线圈安置于颌骨骨折部位，在治疗线圈中通以频率为２．２Ｈｚ的脉冲方波电流，使其在骨折部位激发出低频脉冲电磁场，线圈几何中心磁场平均值约为１．９Ｇｓ，动物实验结果表明该仪有明显促进骨愈合的作用，临床应用颌骨骨折１５例也取得了满意疗效，在机理上作者支持第二信使学说，即电磁场可能是通过激活骨折处成软骨细胞的溶菌酶来促进新骨生长的。
In this paper, a self-developed low-frequency pulsed electromagnetic field jaw healing instrument, the size of 11.2cm × 7.4cm × 3.6cm, the use of special shaped coil placed in the treatment of mandibular fracture site in the treatment coil Through the frequency of 2.2Hz pulse square wave current to make it in the fracture site excited pulsed electromagnetic fields, the geometric center of the coil magnetic field average of about 1.9Gs, animal experiments show that the instrument significantly promote the role of bone healing, Clinical application of jaw fracture in 15 cases also achieved satisfactory results, in the mechanism of the author supports the second messenger theory that the electromagnetic field may be activated by the fracture of chondrocytes lysozyme to promote new bone growth.
