Description

一种高位肛瘘可调型持续牵引挂线装置 技术领域
本发明属于医疗器械领域，具体涉及一种高位肛瘘可调型持续牵引挂线装置。
 背景技术
当前高位肛瘘手术时，因瘘管位置高达耻骨直肠环肌肉水平，切除瘘管需要同步切除耻骨直肠环，但因一次性切断直肠环肌肉会导致大便失禁，肛门移位等严重并发症，因此采用橡皮筋勒紧耻骨直肠环达到慢性切断目的，但橡皮筋在勒断耻骨直肠环过程产生的向心性切割力会导致术后肛门产生钥匙孔样畸形，不利于肛门功能的恢复。

 有益效果
本发明的有益效果在于，将贴合座固定于肛门周围，不影响患者排便，在贴合座上多个位置设计专门的挂线孔，通过圆孔可将肛瘘挂线的橡皮筋固定于牵引单元上，通过旋转调节旋钮可逐渐拉紧橡皮筋，将橡皮筋的向心性切割力调整为单向向下切割，从而减少术后肛门产生钥匙孔样畸形的概率，有助于术后伤口的康复，而且患者可持续穿戴，不影响日常生活，且并可通过牵引单元上的刻度值可以直观的显示当前拉力，根据患者病情量化控制需要牵引的力度。
