Description

支撐骨骼強度的裝置與方法
本發明係屬一種骨骼植入物的技術領域,尤指其技術上提供一種支撐骨骼強度的裝置,透過撐開器模組,可於欲醫治之骨骼內部植入一可以調整不同擴張範圍、多層次弧形之可擴張植入物;藉由注射器模組可將骨水泥依序沿出料孔、通道、中央軸桿之各第二軸向槽孔及外部葉片之各第一軸向槽孔注入該骨骼內部,與已擴張之植入物結合。
骨壞死、骨腫瘤、或骨質疏鬆骨折,經常會合併骨缺損而導致骨塌陷缺損,因此需要接受外科手術以各種植入物或骨移植來治療,骨移植不論是自體骨、異體骨、或是人造骨,都需要經過移行性的骨再造(creeping substitution),才能重塑(remodeling)成正常的骨組織,而在此重塑過程,移植骨的力學結構會降低,當受到外力作用,很容易就會因支撐力不足而再次塌陷,因此必須藉由其他植入物以支撐骨骼結構強度,而這些植入物又必須同時不干擾移植骨的重塑過程。
以股骨頭缺血性壞死為例,目前各種的治療方式仍然不近理想,在早期發現、早期治療者,5年以上的成功率仍僅介於7至8成,失敗的最主要原因是股骨頭內的支撐力不足,而發生持續性的塌陷;以骨質疏鬆脊椎體壓迫性骨 折為例,目前常以經皮式骨水泥椎體成型術進行治療,然而因為骨水泥可能滲漏到脊髓神經周圍引起併發症,骨水泥本身硬度太高又無法被人體吸收,在復原的過程會阻礙骨骼癒合,因此又發展出佝僂成型術治療,利用氣球擴張將脊椎椎體撐開一個空洞,再用骨水泥灌入空洞內,佝僂成型術治療雖然改良了經皮式骨水泥椎體成型術,但是仍然使用高硬度的骨水泥,在骨質疏鬆的病人容易合併鄰近節脊椎椎體再次骨折,氣球擴張的醫療費用又相對高昂,因此有必要加以改良。
是以,針對上述習知結構所存在之問題點,如何開發一種更具理想實用性之創新結構,實消費者所殷切企盼,亦係相關業者須努力研發突破之目標及方向。
有鑑於此,發明人本於多年從事相關產品之製造開發與設計經驗,針對上述之目標,詳加設計與審慎評估後,終得一確具實用性之本發明。
習用之各種移植骨或使用大量異體骨加上去礦質化的骨基質,雖然短期的結果不錯,但是因為支撐力的不足,仍然有偏高比例的失敗率。

前述,該撐開器模組可於欲醫治之骨骼內部植入一可以調整不同擴張範圍、多層次弧形之可擴張植入物。
前述,該撐開器模組之該握把以一專屬骨水泥針筒及一注射握把置換,可組成一注射器模組,該專屬骨水泥針筒包含一推進桿及一外殼,該推進桿可軸向滑移的裝設於該外殼內部,該外殼一端設一出料孔,其內部設有一容置空間和該出料孔相連通,該容置空間係用於盛裝流體,該 流體係為骨強化之混和物(例如骨水泥);該注射握把外周設一第二外螺紋,其一端內部凹設一容置部,另一端設有一扭轉部,該扭轉部呈翼形設置,俾利於使用者扭轉施力,該第二外螺紋螺合於該第二內螺紋,該管體套設於該容置部,使該推進桿抵靠該容置部底部,該出料孔和該通道連通。
前述,該注射器模組可將該流體依序沿該出料孔、該通道、該中央軸桿之各該第二軸向槽孔及該外部葉片之各該第一軸向槽孔流出至該骨骼內部。
一、本發明之支撐骨骼強度的裝置,該撐開器模組透過該握把施加不同力矩,藉由螺紋之扭轉力矩迫使該擴張部均勻地擴張變形,形成一可以調整不同擴張範圍、多層次弧形之可擴張植入物,藉此彈性的擴張構造使植入物和骨骼內部接觸面積增加,因此能夠有效的減少應力集中的現象,並且提供更廣泛的支撐效果。
二、本發明之支撐骨骼強度的裝置,該注射器模組可將骨強化之混和物(例如骨水泥)依序沿出料孔、通道、中央軸桿之各第二軸向槽孔及外部葉片之各第一軸向槽孔流出至骨骼內部,與已擴張之植入物結合,有效提升其支撐強度。
