Abstract
一种闭合式腱鞘钩割器、包括刀体和把柄,其特征在于:刀体前部有梯形槽,刀刃位于梯形槽左侧边上。本实用新型临床应用数百例,无一例发生感染等并发症,操作简单、手术时间短、病人痛苦小、花钱少、无需住院治疗效果显著,还可广泛用于其它多种整形及美容手术。
Description
本实用新型涉及一种医疗器械,特别是一种腱鞘的钩割器。
对具有手术特征的缩窄性腱鞘炎的患者,一般多采用患处切开手术,由于没有专门的手术器械。切除病变处的缩窄腱鞘(膜)。操作程序复杂,难度较大,造成损伤多。切口必须缝合及日后拆线。另一种常用方法“小针刀”治疗,需切开患处部分正常腱鞘(膜),并纵行切开肌腱,盲目性及损伤较大。
本实用新型的目的在于提供一种操作简单,患者损伤小,切口无须缝线的用于腱鞘炎手术的专门医疗器械。
本实用新型的技术方案是:一种闭合式腱鞘钩割器,由把柄和刀体构成,刀体前部有梯形槽,刀刃位于梯形槽的左侧边上。
刀刃和梯形槽底边成锐角,另一端尖锐。
本实用新型操作时只须刺入特定部位,只钩割病变腱鞘及腱膜,使不必要的损伤降低到最低程度,术毕以无菌敷料按压穿刺点数分钟止血,常规包扎,无需缝合,术后24小时开始屈伸功能锻炼。
图1是本实用新型结构示意图。
下面具体叙述实施例:
刀体前10mm打一梯形槽,槽深为刀体1/2,刀刃在梯形槽边,刃口向右,操作时,拇指穿刺点在掌指横放中央远侧0.5cm,其余手指穿刺点均在掌指横放中点处。常规消毒,局部麻醉起效后,用本发明用具沿上述穿刺点刺入皮肤下,使其沿屈肌腱鞘向近端刺入,刀刃及槽口指向皮肤侧穿过缩窄环时可有明显的突破感、稍抬起钩割器前端,保持方向不变渐向远端钩割。张力明显解除后,沿原穿刺口退出,患者活动患指时,弹响消失,绞锁解除,个别患者需钩割2~3次,术后处理按压止血,常规包扎。
本实用新型用于临床500人次,无一例发生感染等并发症,均获成功。操作简单、手术时间短,病人痛苦小花钱少无需住院,治疗效果显著,还可广泛用于其它多种整形及美容手术。
