Description
技术领域
本实用新型涉及医疗器械技术领域，是一种固定于喉部甲状软骨板用于治疗单侧声带麻痹的可调式声带内移固定器。
背景技术
单侧声带麻痹(Unilateral vocal cord paralysis，UVCP)是耳鼻喉科临床较为常见的一种疾病，因有喉部发音、保护及呼吸功能障碍，常伴声嘶、误吸、呛咳等症状，甚至可有失音及肺部感染，严重影响患者生存质量。喉支架外科手术(Laryngeal Framework Surgery)是近年来在临床应用较为广泛的一种嗓音外科手术，又称为甲状软骨成形术。其中甲状软骨成形术I型在治疗单侧声带麻痹中应用最为广泛，其基本手术原理是在患侧声门旁间隙植入硅胶或自体软骨、羟基磷灰石、肽金属、金属小板、Gore-Tex材料等，以达到使患侧声带内移，缩小发声时声门裂隙，改善嗓音质量的目的。有些单侧声带麻痹患者常伴有声门后裂隙过大，往往在采用了甲状软骨成形术I型后也不能达到理想的效果，因为声门旁间隙植入材料并不能使患侧杓状软骨发生内收内移，临床有时也加用杓状软骨内收术以期缩小声门后裂隙。
以上两种术式都是目前临床治疗单侧声带麻痹中应用极为广泛的手术，但这两种术式都存在不足，单纯的甲状软骨成形术I型不能显著缩小声门后裂隙，若患者伴有较大声门后裂隙则术后效果不理想，而且目前临床最常用的硅胶植入材料在术中应用时需不断调整形状及体积，以使声带内移达到理想程度，改善嗓音质量，这种术中的反复调整往往造成喉部软组织的较大损伤，若手术时间过长则会出现声带水肿，影响术中发声效果，进而影响整体手术效果。少部分接受硅胶植入甲状软骨成形术I型的患者术后还出现了排异反应致使植入物排入喉腔，造成严重并发症发生。杓状软骨内收术虽然能使声带发生内移，但其并不具有使声带内收的作用，而且常规的杓状软骨内收术手术切口较大，术中软组织损伤范围较广，为了定位环杓关节，通常需要暴露甲状软骨后部及环甲关节，必要时还要切除部分甲状软骨，术中可能损伤喉粘膜而发生梨状窝穿孔，术后由于喉部软骨框架结构稳定性受影响，可能发生甲状软骨碎裂，局部软组织的术中损伤还可能导致术后出现局部血肿及水肿，严重时可导致呼吸困难等并发症，而且杓状软骨用缝线固定翻转后部分患者不适感较重。
发明内容
本实用新型的目的是提供一种手术操作简便、缩小声门后裂隙效果显著、改善术后嗓音质量明显、术后并发症少的可调式声带内移固定器。
本实用新型由“U”形卡口板和螺钉组成。“U”形卡口板的两片板中间各开有一个螺孔，螺孔设有内镙纹；螺钉由螺杆和螺帽组成，螺帽顶部设有一字形或十字形凹槽，螺杆表面设有外镙纹，该外镙纹与“U”形卡口板上的螺孔内镙纹相匹配；将螺钉通过螺杆从“U”形卡口板一侧的螺孔旋入再穿过“U”形卡口板另一侧的螺孔，就组合成可调式声带内移固定器。
使用时，在喉部甲状软骨板表面开软骨窗后，将“U”形卡口板置于软骨窗并咬合于软骨窗边缘，即“U”形卡口板的一片板在软骨内侧，另一片在软骨外侧，再从“U”形卡口板一侧的螺孔插入螺钉的螺杆，通过螺帽顶部所设的一字形或十字形凹槽，将螺杆旋入，使其穿过甲状软骨板再经“U”形卡口板另一侧的螺孔穿出，直至顶住喉腔内杓状软骨声带突，然后通过螺杆的旋入长度来调节声带内收内移的位置，从而达到缩小声门后裂隙、改善术后嗓音质量的目的。
本实用新型结构简单，操作方便，可调节声带内收内移的位置，能有效固定内移的声带。它的主要优点是：在喉部固定确切，作用更为符合人声带内移内收的生理特点，不仅能使声带发生内移，而且推动杓状软骨声带突使声门后裂隙也能有明显的缩小，从而改善术后发音质量。
