骨科牵引一般要求不易松动,且容易打结和解除。对此,多种专著都介绍了许多有效的方法,但仍觉不便。本人在临床实践中找到一种较有效和更方便的牵引固定方法,介绍如下。取一个1～2.5ml废旧一次性塑料注射器(视所用牵引绳的粗细而定),拔掉活塞部分并冲洗干净。按图1所示剪掉,周边修剪整齐。先将牵引绳穿过注射器,然后牵引绳再穿过牵引架或重物盒,最后将绳头再穿过注射器(逆行),绳头只需打一个结即可。穿绳的顺序和固定后如图2所示。其优点是:(1)方法简便易掌握,材料易取,而且只需打一个结,容易解脱,不浪费牵引绳;(2)固定确实牢固,通过测力计检测在拉力大于30kg状态下,未见任何松动,而一般牵引重量最大是20kg以下(髖关节中心性脱位时的复位重量);(3)外形美观,没有多余
General orthopedic traction is not easy to loose, and easy to knot and lift. In this regard, many monographs have introduced many effective methods, but still feel inconvenience. I found in clinical practice more effective and more convenient traction fixation method, described below. Take a 1 ~ 2.5ml disposable disposable plastic syringe (depending on the thickness of the pulling rope used), unplug the piston and rinse. Cut off as shown in Figure 1, trim around the neat. First pull the rope through the syringe, and then pull the rope through the traction frame or heavy box, and finally the rope through the syringe (retrograde), the rope just hit a knot can be. After the order of the rope and fixed as shown in Figure 2. The advantages are: (1) the method is easy and easy to grasp, the material is easy to take, and only one knot is needed to be easily released without wasting the pulling rope; (2) the fixing is firm, No loosening, while the general maximum traction weight is less than 20kg (hip central dislocation of the reset weight); (3) beautiful appearance, there is no excess
