Description
本发明涉及一种用于固定假体的装置。
在法国,每年会有大约10000个肩关节假体投入使用,其中包括全肩关节假体(被称作标准假体)、反转式假体以及最近出现的表面置换式假体。
这个数字在近些年表现出明显的增加,这尤其归因于表明需要使用肩关节假体的病理学数量的增加。
在该背景下,肩关节假体手术依然是一种非常专业的、高技术含量的外科手术,其需要长时间的学习,并需要利用一些通常很复杂的辅助器材。因此,就需要简化这些假体辅助器材,从而使手术过程更容易进行,可重复性更强,并因此减少手术后的并发症。这种对辅助器材和手术过程的简化也具有降低那些装配肩关节假体手术费用的优势。
目前存在有多种类型的肩关节假体。某些传统的假体,类似美国专利US2004/153161中所述的假体,在完成骨切除后,通过使用肱骨杆将其固定在肱部上。肱骨杆的安装需要在骨头内有很大的凹部来接纳肱骨杆,因此会减少骨量,使骨骼更加脆弱。这种假体的装配耗时长,并且很复杂。在把杆安装在凹部后,骨骼与肱骨杆之间的空间通常填充有骨水泥。一段时间后,骨水泥会脱落,无法确保杆的准确固定。
还存在一种表面置换式假体,类似法国专利FR2,928,827中所述的假体,其是在骨骺表面经过电位光剖后,由肱骨的骨骺代替而成。这种假体不需要像前述的假体那样被固定在骨头内。
当简单的骨骺表面置换术无法采用时,例如当骨头太脆弱时,外科医生会选择使用一种中间性的被称作“半-表面置换”的技术,在该技术中,一部分骨骺被切除。为此目的,那么外科医生就需要使用一种类似于文献EP0,538,895中所描述的假体,其包括用于置换被切除的骨骺部分的托座,以及包括超过其全长的螺纹的锚固螺钉。然后将托座固定在锚固螺钉上。
锚固螺钉的定位决定了托座的定位,并且必须尽可能的精准。由于假体放置得不正确,患者可能会感觉不适或疼痛,这就需要外科医生重新进行手术以对假体重新正确地放置。将用于使假体稳定地锚固在骨头内的锚固螺钉拆除,会导致诸多问题,并使骨头更加脆弱。
文献GB2,199,626描述了一种普通管状的种植体,其具有镂空的下部区域,带螺纹的中部和形成头部的平滑的上部。
文献US2010/191340描述了一种人造的肱骨球头,其包括用于装配管状螺钉的托座,该螺钉的螺纹延伸在其整个长度上。
本发明的目的在于全部或部分地解决上述的各种缺陷。
出于此原因,本发明的目的在于提供一种用于固定托座的装置,其能够保留患者的骨量,并确保更好地、准确快速地固定托座,从而能够在拆卸后不会引起骨头变得更加脆弱。
为此目的,本发明涉及一种用于固定托座的装置,该装置用于植入在骨头内,特别是在肱骨骨骺内,该装置包括:管状体,其沿纵轴线在用于与托座或联结体配合的近端与相背对的用于固定在骨头中的远端之间延伸,管状体界定出内周面和外周面,外周面上设有允许将装置拧入骨头内的螺接装置,该装置的特征在于,该螺接装置包括螺纹,其基本上从近端延伸至外周面的中间区,该中间区设置成与远端和近端相距一段距离,该螺纹具有从近端向中间区增大的可变螺距,该内周面界定出阴型安装部,其从近端延伸出,用于与托座的阳型安装部或联结体的阳型中间安装部相配合。
因此,根据本发明的装置能够在骨质脆弱及无法实施简单的表面置换的情况下,固定标准式或反转式托座。当装置的管状体固定在骨头内,借助螺接装置可正确地将装置锚固,并且依靠互补的安装部的配合可将托座直接或间接地组装在装置上。装配过程得到了简化,特别是由于可简单地将托座联结在装置上。装置的固定可简单地通过如下方式实现:在骨头上形成长度相对于远端距中间区长度有所减小的孔。然后将外周面的未设置螺接装置的部分(即:外周面的位于远端与中间区的部分)插入孔内,并借助螺接装置将该装置完全插入骨头内。在螺接期间,部分骨头插入管状体内,因此可以维持骨量。螺接装置确保将装置合适地固定在骨头内,而外周面的未设置螺接装置的部分参与了装置在骨头内的准直与维持。此外,在装置螺接期间,螺距的变化使骨头压紧,并增强装置的固定。
若有需要,可利用具有适于包围螺接装置的内径的孔锯将装置去掉。借助该孔锯,骨头的与螺接装置配合的部分被切除。鉴于螺接装置没有延伸在装置的整个长度上,而只是在其一部分上,相比较传统的锚固螺钉,其被孔锯切去的长度有所减小。因此,在拆除的情况下,骨量得到维持,致使骨头变得更加脆弱的危险也有所降低。因此,在更换假体的情况下,该螺接装置能够简化装置的拆除。
根据一个实施方式,阴型的安装部为阴型的锥形。锥形容易制成,并且能够使托座与锚固装置准确对齐来实现快速安装。
根据一种可能性,螺纹的螺纹高度从近端向中间区增大。在骨头与螺纹之间的配合面随着螺纹的高度增大,因此增强装置在骨头内的固定。
根据一种实施方式,中间区位于相距近端一段距离处,该距离等于近端与远端的距离的20%至70%之间,优选为40%至50%之间.
根据一种实施方式,管状体具有连接着内周面和外周面、并形成斜面的末端面。该斜面能够利于装置在螺接时穿透骨头。
根据一种可能的方案,外周面的从中间区延伸至远端的部分是基本平滑的。因此,该平滑面能够便于装置的拆除,而不会使骨头变得脆弱。
根据本发明的一种可能的方案,外周面的从中间区延伸至远端的部分具有至少一个穿通管状体的孔。当骨头长回到使骨头的与内周面接触的部分固定至骨头的与外周面接触的部分时,该孔使得骨头更好地再生,尤其不会对去除产生损害。
本发明还涉及一种假体,其包括根据本发明的装置和托座,该托座包括阳型的安装部,其待用于直接或间接地与装置的阴型的安装部相配合。
根据一种实施方式,假体还包括用于设置在根据本发明的装置和托座之间的联结体,该联结体包括可通过形状匹配而与装置的阴型的安装部相配合的阳型的中间安装部,以及可通过形状匹配而与托座的阳型的安装部相配合的阴型的中间安装部。
通过以下的文字说明并结合其中以非限定性举例的方式示出了该装置的一个实施例的附图,将使本发明获得更好的理解。附图中:
图1是假体的各种元件的立体示意图;
图2是图1中的假体的局部剖视立体示意图;
图3是图1中的假体植入肱骨骨骺内的立体示意图。
如图1所示,假体1包括装置2和待安装入装置2的托座3。
托座3具有中空球形帽4,其具有内表面5和锥形的、从球形帽4的内表面5的中心凸出的中心杆6。中心杆6界定出阳型的安装部7,其形成阳型的莫氏椎体8。
可选地,在图中示出的实施例的情况下,假体1还包括联结体9。该联结体9包括基本为锥形的、具有形成为阳型的莫氏椎体12的阳型的中间安装部11的第一部分10。如图2所示,联结体9还包括第二管状部13,其开设有腔14,腔14基本为锥形并限定出阴型的中间安装部15。阴型的中间安装部15形成阴型的莫氏椎体16,其大小被设置成通过形状匹配而与托座3的阳型的安装部7相配合。根据图中所示的实施例,联结体9具有阳型的莫氏椎体12和阴型的莫氏椎体16,其各自的对称轴是重合的。作为一种备选方案(未示出),阳型的莫氏椎体12和阴型的莫氏椎体16,其各自的对称轴是不同的、偏移的,和/或不平行的。
如图3所示,装置2包括:管状体17,其沿纵轴线A在用于直接或间接与托座3或联结体9配合的近端18与相背对的用于固定在骨头21的骨骺20中的远端19之间延伸。当托座3用于设置在的肩胛骨23的关节盂22(其部分地在图3中示出)之内时,骨头21对应为肱骨。
如图2所示,管状体17界定出内周面24以及外周面25。外周面25上设有制成螺纹26的形式的螺接装置,从而允许将装置2拧入骨头21内。
螺纹26基本从近端18延伸至外周面25的位于与近端18和远端19相距一段距离的中间区27。中间区27位于相距近端18的一段距离处,该距离等于近端18与远端19之间的间距的20%至70%之间。
螺纹26具有可变的、沿着螺纹26从近端18朝向中间区27增大的螺距。螺纹26的螺纹高度亦随着螺纹26从近端18朝向中间区27而增长。
内周面24界定出阴型的安装部28,其基本从近端18延伸出,并且其大小被设置成通过形状匹配而与联结体9的阳型的中间安装部11相配合。在一个未在图中示出的实施例中,阴型的安装部28的大小被设置成通过形状匹配而与托座3的阳型的安装部7相配合。
管状体17具有连接着内周面24和外周面25的末端面29。该末端面29形成斜面30,其能够便于通过螺接方式将装置2插入骨头21中。
外周面25的从中间区27延伸至远端19的部分是基本上平滑的,并具有4个穿通管状体17的孔31。
最后,装置2包括4个槽口32,其形成在螺纹26的近端18处。这些槽口32用于与螺拧工具配合,以使将装置2拧入骨头21内的操作更简便。
因此,根据本发明前述的装置2能够固定托座3。当装置2的管状体17固定在骨头上时,通过螺纹26可以保证装置2的正确锚固。由于将托座3联结在装置2上是简单的,因此使得装配过程简化。
若有需要,可利用孔锯按照前述的方式将装置2去除。由于装置2,骨头21的与螺纹26相配合的部分和待被切除的部分有所减少,因为螺纹26并不在装置2的整个长度上延伸。在这种情况下,在拆除装置2时,既可以维持骨量,同时还可以降低使骨头21变得更加脆弱的危险。
当然,以上提供的示例性实施例绝不是限制性的,并且,依据本发明的装置2在没有超出本发明的范围内均会有细化或改变之处,装置2也可能会有其他形状的产生。
