Abstract

本实用新型属于骨外科治疗股骨颈骨折,股骨头无菌性坏死,类风湿性髋关节炎,髋关节结核骨性溶合,变形性髋关节病等疾病的一种新型内固定手术器材。本髋关节假体上多了一个纵向稳定孔,定位孔和定位标记,并另配一套骨矩分力装置,可以在骨矩缺损的情况下,进行人工假体置换术;亦可利用分力装置作用,防止骨矩疲劳性骨折,假体旋转及脱落。

Description

一种带有骨矩分力装置的髋关节假体
本实用新型属于骨外科治疗髋关节变形性关节炎、类风湿、股骨头无菌性坏死。股骨头囊内性骨折等疾病的一种由医用不锈钢材质制造的新型手术器材。
现国内外公知的人工全髋关节、人工股骨头,均不具有修复坏损骨矩及使骨矩受力分散的作用。在骨矩损坏的情况下,不能进行假体置换手术;或存在骨矩的情况下,置换假体后造成骨矩疲劳性骨折。另外,临床上假体置换后,发生假体放置脱落者也时有所见。为解决这一问题,手术中往往使用骨水泥充填,而骨水泥的毒性作用可以使手术中的病人血压下降为0。
本实用新型、具有手术重建骨矩,使骨矩受力分散而防止骨矩凹陷,骨折以及防止假体旋转、松动、脱落的作用。其特点是:
图1假体主体(1-1)柄上多了一个呈纵向长圆型的稳定孔(1-2),在颈部多设了一个定位孔(1-3)和定位标记(1-4),并另设一套骨矩分力装置。分别介绍如下:
稳定孔(1-2):顺柄中心矢状线方向的一个长圆孔,使用时分力杆通过此孔,可防止假体转动。
定位孔(1-3):可容一细克氏针,术中指导定向定位钻孔位于中心矢状线。
定位标记(1-4):与定位孔同时指导定位定向钻孔,位于中心矢状线上。
图2分力板(2-1):稳定大转子下段,使之为骨矩分力。
骨矩维持板(2-2):稳定和重建骨矩。有两个翼板和一个固定孔。
分力杆(2-4):为一个半扣螺丝和管状螺母所组成的螺栓。
分力杆的管状螺母(2-3)。
分力状置图2及手术中分力装置的安装位置图3。
使用方法:臀后切口加粗隆下外侧切口,或改良臀后切口(臀后切口远端转向粗隆下2cm。呈
Figure 86201016_IMG2
型)。
放置好人工假体主体(1-1)后,髋关节屈曲内旋位。在定位孔(1-3)插入一细克氏针和定位标记(1-4)共同指导安放骨矩维持板(2-2)。钻孔。孔在此向外钻透两层骨皮质,中间穿过稳定孔(3),在对侧皮质扩孔后装上分力板(2-1)及管状螺母(2-3),并旋入旋紧拉力杆(2-4)。

Claims (7)
