Description

胸骨固定卡 技术领域
本实用新型涉及一种植入医疗器具， 具体涉及一种用于胸骨纵向切幵后 或胸骨骨折复位的骨固定的胸骨固定卡。 背景技术
目前， 胸骨纵向切开是胸心外科常用手术入路， 手术后闭合胸骨以及胸 骨骨折的复位内固定的传统方法有： 方法 1、'胸骨打孔预穿钢丝； 方法 2、 缝 合针穿带钢丝； 方法 3、 可吸收胸骨钉。 其中， 方法 1和方法 2均采用钢丝捆 扎， 在胸骨上打孔或用缝合针穿过胸骨， 穿钢丝和穿缝合针时均有可能对脏 器造成损伤， 胸骨上的打孔或缝合针眼可能导致出血； 若捆扎钢丝较松， 对 胸骨固定不牢靠， 起不到坚固作用， 若捆扎钢丝过紧， 可能导致钢丝张力过 大断裂， 起不到固定作用， 还有可能对胸骨下的脏器造成损伤， 导致医疗事 故的发生； 而且术后钢丝取出困难。 方法 3 在使用胸骨钉时也需要胸骨打孔 和钢丝捆扎， 其不足之处和方法 1、 方法 2基本等同。 发明内容
本实用新型的目的在于提供一种结构合理， 固定可靠， 有利于胸骨骨骼 血运重建和骨骼生长恢复的用于胸骨纵向切开后或胸骨骨折复位的内固定的 胸骨固定卡。
本实用新型的目的是这样实现的： 一种胸骨固定卡， 其特征在于： 该胸 骨固定卡由单体的横梁和分别与所述横梁两端连为一体的 U形弯钩组成。
上述横梁为平直状， 或弧形状， 或其中部段为平直状、 两端弧形过渡与 所述 u形弯钩连接。 ，
上述横梁和所述 U形弯钩的横截面为矩形， 或为椭圆形或为圆形， 所述 U 形弯钩的钩头的端部为尖角形。 上述 u形弯钩的横截面为椭圆形或为圆形， 其 u形弯钩的钩头的端部也 可为锥形。
上述横梁和所述 u形弯钩的表面光洁， 其平面的相交棱和尖角处倒圆。 可采用上述横梁和所述 u形弯钩的横截面为椭圆形， 所述横梁为弧形状， 所述钩头的端部为锥形的胸骨固定卡。
也可采用上述横梁和所述 u形弯钩的横截面为圆形， 所述横梁为弯折状， 该弯折段所在平面与两个所述 u形弯钩端面所在的平面相垂直， 所述钩头的 端部为锥形的胸骨固定卡。
本实用新型的胸骨固定卡可使用各种类型的适用于人体内置的具有形状 记忆功能的合金材料制成。
横截面为矩形结构的胸骨固定卡占用空间的体积较小， 强度高， 而圆形、 椭圆形结构占用骨膜表面积较小； 此外应根据人体胸骨连接部位的外表面形 态选择相适应形状的横梁结构的胸骨固定卡。
本实用新型的胸骨固定卡在使用时， 当胸腔内手术操作完成或胸骨骨折 复位后， 用关胸器或髌骨复位钳将胸骨对位处准确临时固定， 取测量装置测 量左右对称两肋骨间隙之间的胸骨宽度， 选择比胸骨宽度数据略小于本实用 新型的胸骨固定卡安装， 在不同的固定部位可选择不同结构的胸骨固定卡， 在对所需固定的部位逐一测量安装固定后， 卸下关胸器或髌骨复位钳， 检査、 清洗、 缝合皮肤， 手术完成。
本实用新型的优点是： 1、 采用了具有形状记忆功能的合金材料， 使得胸 心外科手术闭合胸骨时手术操作极为简便。 2、 提高了手术操作的安全系数， 降低医疗事故的风险。 3、 有效的缩短了手术时间， 减少病人的痛苦。 4、 设 计简单， 结构合 S, 符合人体骨骼的结构特征， 对胸骨起到安全、 有效、 可 靠的固定作用。 5、 中部横梁的单梁设计， 有效的减少胸骨表面的血运遮挡， 有利于胸骨的血运重建和骨膜软组织的生长。 6、 愈合术后取出安全、 容易。 体积小， 异物感觉不明显， 甚至有的病人愈合后不需要取出。
综上所述的， 本实用新型的用于胸骨纵向切开后或胸骨骨折复位的内固 8 000526 定的胸骨固定卡结构合理， 固定可靠， 有利于胸骨骨骼血运重建和骨骼生长 恢复。 附图说明
