Description

一字型手爪式髌骨外固定器
技术领域
本实用新型涉及一种医疗手术用的固定器,该固定器主要用于人体膝关节髌骨骨折或粉碎性骨折的外固定。
背景技术
目前在医疗领域中髌骨骨折普遍使用的固定方法有多种,最常见的有张力带内固定,1、就是手术开刀用钢丝固定,2、穿钢针绕钢丝等,这些手术创伤大,伤口恢复过程耽误关节功能锻炼时机,髌骨增大常出现膝关节粘连功能不到位,最直观的弊端患者还要受第二次手术带来的痛苦;3、目前现有的一些外固定器,安装繁琐,固定可调范围局限,关节功能锻炼被固定器本体阻碍,有的创伤大,医界很少推广;4、民间传统中医保守治疗,用外固定绑扎法,优点:没有伤口,缺点:骨头整合难到位,稳定性差,难以保护,耽误关节锻炼时机髌骨增大变形,影响关节功能质量,甚至难免出现压迫性溃疡等更严重的后果。
发明内容
本实用新型所要解决的技术问题是提供一种一字型手爪式髌骨外固定器,使用这种固定器医生可根据患者髌骨骨折的移位情况,事先安装好固定器,一般不是特别严重的粉碎性髌骨骨折不需要开刀手术,可直接将安装好的固定针打入髌骨最佳位置固定,手术简便,定位可调稳固,膝关节功能可以提早锻炼,为患者不要受第二次手术的痛苦,是骨科医学髌骨微创治疗新技术。
为此,本实用新型所提供的一字型手爪式髌骨外固定器,为了不同的髌骨骨折移位匹配,设计了两款:“爪式与手式”,爪式有四个固定点,犹如“鹰爪”微创坚固,手式有五个固定点,好比“五指”灵敏稳定;A、爪式:该固定器包括一字型主梁,主梁两端设有调压固定件,一端设有调压螺帽,两端下面设有弧型付梁,付梁两端设有付固定件,及固定针。
B、手式:该固定器包括一字型主梁,主梁一端设有调压固定件,调压螺帽,下面设有弧型付梁,付梁两端设有付固定件,及固定针;主梁另一端设有q形固定件,下面设有b形固定件及固定针;中间设有辅助固定件,辅助固定件两端设有八字形针座及辅助固定针。
由于本实用新型一字型手爪式髌骨外固定器,A款:主梁两端设有调压固定件,为了方便安装和选择需要设计了两款,通过调压螺帽推动调压固定件能调节到最佳位置固定,调压固定件下面设有弧型付梁,弧型付梁中间设有校准固定孔对孔固定,《如遇髌骨移位特殊根据需要也能左右移动不对称定位》,弧型付梁两侧设有付固定件,移动付固定件能对横向进行调节,转动付固定件能对斜度进行调节,多方位调节的设计能解决不同髌骨骨折移位的匹配,付固定件下端设有穿针孔,固定针穿进后有加固螺帽调节到最佳位置有紧定螺丝固定。
B款:主梁一端设有调压固定件,另一端设有q形固定件,主梁中间设有辅助固定件,通过调压螺帽推动调压固定件能调节到最佳位置固定,调压固定件下面设计与A款相同;另一端q形固定件下面设有b形固定件,由于b形固定件是单针孔设计,为了解决髌骨骨折移位超前面积极小设计的,不同位置的需要可以转动调节斜度,固定针穿进后有加固螺帽调节到最佳位置有紧定螺丝固定;辅助固定件的设计是为了八字形针座配套用的,根据不同位置髌骨粉碎性骨折需要前后移动有紧定螺丝固定;八字形针座的设计可转动能调节辅助固定针角度,中间小半圆的设计是为了方便折弯调节角度,椭圆形针孔的设计左右可移动有利于辅助固定针的空间调节,辅助固定针穿进椭圆形针孔后有加固螺帽调节定位(详见图7)。备注:1、辅助固定件、八字形针座、辅助固定针三件套属辅助固定,根据髌骨骨折移位需要A、B款都可以配用或不用;2、弧型付梁、调压固定件两款设计,根据需要A、B款可以互换组合。
