Α7 Β7 五、發明説明(1 ) 本發明係關於一種髖關節膺復物,附有一根桿將*** 知骨内’以一件式聯結至頸轴承上端及具有縱切槽。 桿之縱切槽可改善力量由膺復物傳遞至周圍骨。此點 對於無膠合劑植入之病例特別重要。此種病例中,股組織 於癒合過程中生長入切槽内,及或多或少牢固聯結膺復物 表面。但膺復物經配備有切槽也有助於經膠合的植入病例 。若於追蹤手術時,位於切槽内部的骨材或膠合劑材料必 須再度去除,外科醫生須由近端將適當鑿刀引進切槽内。 其先決要件為切槽可由近端接近。 經濟部中央樣準局員工消費合作社印製 (请先閲讀背面之注意事項再填寫本頁) 股骨競關節膺復物為已知(EP-B 93378,第1及2圖), 其具有頸軸承設計成與桿呈單件式。桿設置有縱肋,介於 肋間形成深切槽。於上端,肋及切槽遠至頸軸承且由頸轴 承劃界線。因頸轴承由關節方向覆蓋切槽空間,此種空間 於追蹤手術時難以接近。因此也曾提議(同案第5圖)將搭 接部件製造成活動式’而植入膺復物,但未揭示膺復物的 聯結情況》類似已知膺復物(Waldemar Link(GmbH &公 司)手冊:「聯結肋系統」)中,馬蹄形頸軸承之臂固定於 桿之前及後導溝。當頸轴承移開時,於導溝區並未存在有 凸出部件來妨礙手術接近《但導溝於桿之縱向方向為橫向 延伸,故許多情況下不合所需,原因會減少桿的剖面積因 而降低桿強度。此外,有關頸轴承之可靠度,許多醫生偏 好以單件式聯結於桿的頸轴承。 已知股骨髖關節膺復物(FR-A 2 595 241),其免除此 本紙朱尺度適用中國國家標準(CNS ) Α4規格(2ΐ〇χ297公釐) 4 經濟部中央標準局員工消費合作社印製 A7 B7 五、發明説明(2 ) 一~;— 種問題之辦法係以頸軸承之方式設置小凸出部,但僅設置 於膺復物桿之無切槽中央窄側,而設置有切槽之桿之前侧 及後側皆不含頸轴承。但曾經嘗試形成大表面積之頸轴承 俾減少骨被頸轴承之比負載,因此該發明之條件為頸麵承 也存在於配備有切槽之桿兩侧上。 本發明揭示一種競關節膺復物,其雖然存在有頸轴承 以整合一體式聯結至桿,但其切槽空間可接近。解決辦法 在於頸軸承與切槽區設置有切出部,及縱切槽止於頸轴承 上方。換έ之,縱切層持續貫穿頸轴承區,頸轴承被切槽 所切開。因此於追蹤手術時可將器械引進切槽内而清除切 槽區的骨質聯結;或於植入過程中使用切槽空間來填塞骨 質材料。雖s如此,膺復物具有頸軸承,其整合一體聯結 至桿。許多情況下,於切出部外側有頸軸承提供的表面足 夠提供支撐。若需要較大軸承面積,則根據本發明可使用 活動搭接部件提供,搭接部件主要封閉縱切槽區的切出部 。頸軸承及/或桿形成滑動導件,導件平行頸軸承的形成 延伸且沿此導件搭接部件可***或去除而植入膺復物。 將參照附圖闡釋優異範例具體例說明本發明之進一步 細節如下,附圖中: 第1圖顯示膺復物之側視圖,及待推上的搭接部件剖 面圊, 第2圖顯示待推上的搭接部件之平面圖, 第3圖顯示膺復物之側視圖, 本紙張尺度適用中國國家標準(CNS) A4規格(210x297公釐) (請先閲讀背面之注意事項再填寫本頁) 裝· 訂 經濟部中央榡準局貝工消費合作社印裝
