摘　　要：目的:设计一种能与在用的铲式担架进行简易连接的颈椎牵引支架,使颈椎及上段胸椎损伤的患者在院前急救、转运、入院检查以及术前准备阶段均能获得早期、持续及自动的颈椎牵引,实现治疗前颈椎牵引,以改善预后。方法:1采用组合滑轮与弹簧绳钩代替普通牵引所使用的重锤;2通过对接式齿轮连接块,可将牵引支架固定在担架上;3调整连接块上的齿轮状卡槽,以改变牵引的方向。结果:牵引力预实验使用ES-58拉伸弹簧系列,弹簧绳钩挂15 cm距离可产生0.75 kg牵引力,双侧共1.5 kg牵引力;17 cm距离双侧可产生4.0 kg牵引力;18 cm距离双侧可产生5.0 kg牵引力。结论:此装置拆卸简便,不影响担架在其他场合的使用,除常规医疗救护外,尤其适用于应急救灾与军事医学救治。Objective： To design a kind of trestle connecting to scoop stretchers action as automatic cervical vertebra tractor. To improve the outcome, treatment of early cervical vertebra traction going to start since the first aid, on transport, waiting for examinations and operating for the patients of spine injury including cervical vertebra and upper thoracic vertebras. Methods： The heave matter use to be hang for cervical vertebra traction instead by couple of mechanical springs each gets through a couple of pulley wheels. The trestle connect to the scoop stretcher with a special conjunction. The special conjunction can be connected in different grooves to change the angle of traction. Results： Mimetic tests shows that 0.75kg of single force made by a distance of 15 cm pulled with the mechanical spring of ES-58, made by Fuzhou Hengsheng spring Co. Ltd. The practical force would be double, 1.5kg. Similar, distance of 17 cm for 2.0 kg of single spring force and 4.0 kg of practical force, 18 cm for 2.5 kg and 5.0 kg. Conclusion： The trestle of automatic cervical vertebra tractor is easy to be connect to and dismantle from scoop stretcher without damage to the intrinsic function of stretcher, and have a wildly purpose for not only medical aid but also disaster relief even for martial purpose.
