Description

一种剥离上颌窦粘膜的记忆弹性丝套管 技术领域
本发明涉及一种医疗器械，具体涉及一种剥离上颌窦底粘膜的记忆弹性丝套管，适用于分离上颌窦底粘膜的种植和(或)植骨手术。
背景技术
口腔种植学是近年口腔医学发展最快的领域之一，临床常见上颌磨牙区牙槽嵴顶距离上颌窦底较近时，植入植体往往会因与植体结合的骨过少而增加植体失败率。垂直骨量不足的上颌后牙区曾一度被认为是种植牙的禁区。上颌窦提升技术一经提出就为解决上述问题带来可能。上颌窦提升术分为侧壁开窗的上颌窦底提升术，即上颌窦外提升术(Tatum OH.Maxillary and sinus implant reconstruction[J].J Dent Clin North Am，1986，30(2)：207-229.)和经牙槽嵴顶入路的上颌窦底提升术，即上颌窦内提升术(Summers RB.The osteotome technique.Part 3：Less invasive met hods in elevation of the sinus floor[J].J Compendium of Continuous Education in Dentistry，1994，15：698-708.)。侧壁开窗的上颌窦底提升术能够较大面积地剥离上颌窦底粘膜，减少窦底粘膜的张力，可植入较多骨粉有效增高窦底的骨高度，扩大了种植适应症，但技术较复杂，应用现有器械手术费时较长，当剥离范围增大时穿孔机会增多，在临床推广应用中受到一定限制。经牙槽嵴顶入路的上颌窦底提升术具有手术创伤小、术后并发症少、缩短治疗时间、费用低等优点，近年来受临床医师的重视和欢迎，但当其提升幅度大于5mm，上颌窦粘膜撕裂风险明显增加，常见的并发症有窦粘膜穿孔、死骨形成和上颌窦炎。近年球囊、液压、超声骨刀等先进技术用于经牙槽嵴顶入路的上颌窦底提升术增加提升高度，降低上颌窦粘膜穿孔危险，但是提升高度有限，据国内外文献报道可提升2-7mm高度(邱立新，胡秀莲，陈波，等.上颌窦底冲压提升法种植修复122例缺牙的临床观察[J].中华口腔医学杂志，2006，41：136-139；Nedir R，Bischof M，Vazquez L，et al.Osteotome sinus floor elevation without grafting material：a 1-year prospective pilot study with ITI implants[J].J Clin.Oral Impl.Res，2006，17：679-686；Winter AA，Pollack AS，Odrich RB.Sinus/alveolar crest tenting(SACT)：a new technique for implant placement in atrophicmaxillary ridges without bone grafts or membranes[J].The International Journal of Periodontics&Restorative Dentistry，2003，23：557-565)。主要原因在于内提升手术 虽然创伤较小，但器械剥离窦底粘膜范围较小。
本发明针对目前器械剥离窦底粘膜中遇到的问题创造性的提供一种医疗器械，既能经牙槽嵴顶入路又能经侧壁开窗大范围剥离上颌窦底粘膜，安全有效，具有很好的临床应用价值。
发明内容
本发明的目的是提供一种剥离上颌窦粘膜的记忆弹性丝套管，包括初级剥离结构和次级剥离结构，所述初级剥离结构由中空套管(2)以及位于中空套管顶端的剥离刃(1)组成，所述次级剥离结构为弹性丝(4)，其特征在于，所述弹性丝(4)具有超弹性和/或记忆性，弹性丝(4)从中空套管(2)底部穿入，剥离刃(1)控制弹性丝(4)向着中空套管(2)的前下方伸出。
进一步，弹性丝(4)伸出中空套管(2)的部分称为剥离丝(8)，剥离丝(8)大小、伸出方向、形状均可变。
进一步，弹性丝(4)弯折形成双股，所述弹性丝(4)伸出中空套管(2)的部分称为剥离丝(8)。
进一步，对弹性丝(4)进行加工，使之形成适于上颌窦底粘膜剥离的形状，产品组装过程中将弹性丝(4)穿入中空套管(2)内。优选的，所述适于上颌窦底粘膜剥离的形状为弧形或锥形等。
进一步，剥离丝(8)呈不规则圆。
进一步，剥离丝(8)膨大，使剥离丝(8)隐藏在剥离刃(1)内；但不能继续缩进中空套管(2)。
进一步，中空套管(2)的剥离刃(1)为弧形和/或中空套管(2)的末端具有把持端(3)和/或弹性丝(4)的末端具有止动塞(7)和/或中空套管(2)上标有刻度和/或弹性丝(4)上标有刻度。优选刻度之间的距离为0.5-1mm。优选把持端(3)的大小以方便把持即可，更优选的把持端(3)直径为7mm以上。
当弹性丝(4)弯折形成双股时，每股末端都有一个止动塞(7)，推拉止动塞(7)时，弹性丝(4)随着伸缩，剥离丝(8)大小改变；止动塞(7)旋转时，带动弹性丝(4)旋转，剥离丝(8)翻转；止动塞(7)保持不同运动时，剥离丝(8)形状改变；一个止动塞(7)不动，另一个止动塞(7)运动时，剥离丝(7)形状改变。优选的，止动塞(7)可以沿着弹性丝(4)移动并在指定的位置处固定。更优选的，在 上颌窦粘膜剥离之初，仅用初级剥离结构时，将止动塞(7)移动到弹性丝(4)中段并固定，从而使剥离丝(8)隐藏在剥离刃(1)里同时不能继续缩进中空套管(2)。
进一步，所述记忆弹性丝的材料为非金属和/或金属合金。
进一步，中空套管(2)直径为1-4mm、弹性丝(4)直径为0.3-0.6mm、剥离刃(1)的长度为1-5mm。优选中空套管(2)直径为2-3mm、弹性丝(4)直径为0.3-0.46mm、剥离刃(1)的宽度为3-4mm。
本发明的目的在于提供一种记忆弹性丝套管的套件，所述套件由数套不同型号、不同大小的记忆弹性丝套管组成。进一步，套件中弹性丝(4)直径为0.3048mm(0.012英寸)、0.3556mm(0.014英寸)、0.4064mm(0.016英寸)等。
本发明中，初级剥离结构可以单独剥离上颌窦粘膜，次级剥离结构需要借助初级剥离结构方能剥离上颌窦粘膜。
本发明可以实现广泛的剥离上颌窦底粘膜，有利于提升骨高度。通过羊动物实验和临床试验，在平坦的窦底获得的剥离长度为23.03±4.92mm，具有60°～90°坡度窦底剥离长度为19.00±5.06mm。
本发明的优点有以下几个方面：
1、本发明比传统单一的剥离器剥离粘膜范围更广。
2、次级剥离结构以超弹性和/或记忆性弹性丝作为钝刃剥离粘膜，剥离效果好。
3、在实施过程中，本发明具有二级剥离结构(初级剥离结构和次级剥离结构)，能完成五种操作：
(1)使用初级剥离结构初步剥离上颌窦底粘膜；
(2)启用次级剥离结构，剥离丝伸出剥离刃，实现进一步剥离上颌窦底粘膜；
(3)水平旋转中空套管，带动剥离丝水平旋转，剥离入口平面周围的粘膜；
(4)固定中空套管，水平转动弹性丝或止动塞，使剥离丝翻转，剥离陡升骨壁的粘膜；
(5)固定中空套管，两端弹性丝或止动塞保持不同运动，改变剥离丝形状，剥离粘膜。
4、本发明提供的记忆弹性丝套管设备简单小巧。
5、本发明提供了记忆弹性丝套管的套件，可以根据种植窝孔的直径挑选不同型号的中空套管，根据粘膜的韧性选择不同直径的弹性丝，其富有弹性及强度，力量轻柔，可以有效减少上颌窦粘膜穿孔概率，方便临床中实际操作。
本发明所指的弹性丝是指由非金属或两种或两种以上的金属与金属(或非金属)经一定方法合成的具有超弹性和/或记忆性特性的物质。超弹性是指材料存在一个弹性势能函数，该函数是应变张量的标量函数，其对应变分量的导数是对应的应力分量，在卸载时应变可自动恢复的现象。应力和应变不再是线性对应的关系，而是以弹性能函数的形式一一对应。记忆性是指材料变形后可以恢复的性能。
本发明所指的弹性丝截面不仅仅局限为圆形，还可以是椭圆形、四边形、多边形等各种形状。
剥离刃是指初级剥离结构中位于中空套管顶端的部分，剥离刃能够控制弹性丝向着中空套管的前下方伸出。优选剥离刃为弧形。
发明利用了弹性丝的超弹性和/或记忆性，在产品制备之初，首先对弹性丝进行加工，使之形成适于上颌窦底粘膜剥离的形状，产品组装过程中将弹性丝伸入中空套管，使用时，剥离丝仍保持着适于上颌窦底粘膜剥离的形状。此外，记忆弹性丝套管在使用过程中需要弹性丝的超弹性和/或记忆性适应各种复杂的剥离情况。

具体实施方式
下面结合具体实施例，进一步阐述本发明，仅用于解释本发明，而不能理解为对本发明的限制。本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
实施例1
初级剥离结构剥离上颌窦底粘膜：将中空套管2缓慢放入到骨孔10，手持中空套 管2或把持端3，用剥离刃1剥离粘膜，缓慢水平旋转中空套管2将上颌窦底粘膜11剥离一圈，获得扩孔周围约3mm剥离范围。
实施例2
次级剥离结构剥离上颌窦底粘膜：将中空套管2缓慢放入到骨孔10(此时剥离丝8隐藏在剥离刃1内)，操作弹性丝4或止动塞7使剥离丝8沿剥离刃1向前下方伸出。根据需要提升的高度选择适宜的剥离长度。
实施例3
次级剥离结构剥离上颌窦底粘膜：将中空套管2缓慢放入到骨孔10(此时剥离丝8隐藏在剥离刃1内)，操作弹性丝4或止动塞7使剥离丝8沿剥离刃1向前下方伸出。进而，水平旋转中空套管2或把持端3并带动剥离丝8旋转，以扩孔中点为中心垂直于扩孔平面旋转，可以较大范围剥离孔周粘膜。
实施例4
次级剥离结构剥离上颌窦底粘膜：将中空套管2缓慢放入到骨孔10(此时剥离丝8隐藏在剥离刃1内)，操作弹性丝4或止动塞7使剥离丝8沿剥离刃1向前下方伸出。当扩孔远处骨壁陡升，由于剥离刃1限制剥离丝8只能向前下方伸出，使得剥离丝8向前伸出受阻，这时可以固定中空套管2或把持端3并转动弹性丝4或止动塞7，使得剥离丝8以剥离刃1为中心发生翻转，继而剥离邻近陡升的上颌窦粘膜11，并进一步匍向更远处。
实施例5
次级剥离结构剥离上颌窦底粘膜：将中空套管2缓慢放入到骨孔10(此时剥离丝8隐藏在剥离刃1内)，操作弹性丝4或止动塞7使剥离丝8沿剥离刃1向前下方伸出。固定中空套管2，使两个止动塞7保持不同运动，使得剥离丝8形状改变，用不同形状的剥离丝8剥离粘膜。或者固定一端弹性丝4或止动塞7，拉伸另一端弹性丝4或止动塞7，使得剥离丝8形状改变，用不同形状的剥离丝8剥离粘膜。
