519488 經濟部智慧財產局員工消費合作社印製 A7 B7 五、發明說明(/ ) 【發明背景】 本發明係有關於一種用於骨(特別是脊椎)融合的裝 置’且特別是關於一*種用於植入物之端構件,以用於融接 骨或是特別地如申請專利範圍獨立項第1、37及38項前 言所界定之脊椎。 骨缺陷的治療及處理對整形外科的觀點而言仍然是最 大的挑戰之一。骨的缺陷係發生在臨床情況之廣泛的變化 中。將任何具有骨缺陷點的長骨恢復其自然的解剖長度及 形狀是有問題的。此外,每當有一脊椎骨需要被移去,則 必須插入一脊椎間隔物以恢復脊椎之自然長度及曲度且可 促進骨融合。在身體的切除(corpectomy)手術中,恢復 脊椎的解剖構造及穩定性與促進骨融合係更加的困難,該 身體的切除手術係爲一種將一個或多個脊椎片斷移除的外 科手術。 許多不同之植入物係被發展出來以使用於具有缺陷之 骨。所謂之“網狀植入物(mesh implants) ”係顯示特別 的有效。該植入物之其中一種係爲可由美國賓州波里( Paoli)之 Synthes 公司買到的 SynMesh™。該 SynMesh™ 是一種鈦金屬網狀圓柱,該網狀圓柱之表面上係分佈有複 數個相同大小之相同間隔孔洞。爲了處理在不同之臨床情 況中所產生之骨缺陷,該SynMesh™係可用於各種長度及 直徑。近來,用於治療骨缺陷之商業上可用的同種異體移 植(allograft).,係變得可用。 雖然該網狀物及同種異體移植之植入物的臨床結果係 4 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) ------------t--------訂·! i· (請先閱讀背面之注意事項再填寫本頁) 經濟部智慧財產局員工消費合作社印製 519488 A7 B7 五、發明說明(j) 大致地爲正面的,該植入物在臨床上可能的倂發症係爲沉 靜了。無論該骨頭係具有極其之滲透性,當該植入物的末 端過度的陷入骨頭時,其接觸係特別地令人困擾。從機械 及生理學的觀點而言,增加植入物與骨之間的表面接觸區 域亦是有利的。美國專利案第5,702,451號Biedermann 等人係揭示一種端部環圏,其係試圖提出該等利害關係。 然而,該揭示的端部環圏係沒有提供用以握持、插入及切 開的工具。因而,移植係可能爲困難的。 此外,在移植後,於骨頭與該揭示的端部環圈之間係 可能有過過的移動。如此係可能延遲及可能阻礙骨融合。 綜上所述之討論,一種用於骨融合移植之端構件係爲 必要的。 【發明槪要】 本發明係錯由一種用於骨(特別是脊椎)融合的裝置 ,且尤其是藉由一種用於骨融合移植或特別是脊椎融合移 植之%構件而解決此問題,其中該脊椎融合移植之特徵係 在於申請專利範圍中第1、37及38項所述之特色。 本發明係關於一種用於與一骨融合植入物使用之端構 件,以用於融接骨部分。該端構件係具有一個第一部分、 一個按尺寸製造以插入該植入物之孔內的第二部分,及一 個介於該第一及第二部分間的肩部。當該第二部分被插入 孔內時,該肩部係靠在植入物之一邊緣上。該第一部分的 頂面係與骨的大小及形狀一致,且具有一個或多個通道以 容納一外科手術的工具。當存在有多個通道同時,所有的 5 本i張尺度適用中國國家標準(CNS)A4規格(210 X 297公爱)' ' --------------------訂---------線 (請先閱讀背面之注意事項再填寫本頁) 519488 經濟部智慧財產局員工消費合作社印製 A7 B7 五、發明說明(3 ) 通道可以相同的方向運轉(例如,該通道係以前方偏側的 方向而運轉),或通道係可以不同的方向運轉(例如,第 一通道係以前方偏側的方向運轉,而第二通道係以側面的 方向運轉)。 若該植入物是由金屬製成,該端構件亦用相同的材質 製造以爲了抵抗腐蝕。該端構件亦可用同種異體移植之骨 所製成。該端構件係可能具有一個楔形或球形的外觀,其 係爲了恢復骨頭的自然曲率或是校正一種非正交的切骨手 術。一種創造該楔形外觀的方法係爲使該第一部分的第一 端部比該第二端部較爲粗厚。 該頂面係可被製成各種適當的截面形狀,例如橢圓形 、長方形或是圓形,且係可爲環形或實心的。該頂面係可 爲一水坦的平面或者可具有一模擬骨形之彎曲度。該頂面 係可能提供有齒狀物或架構以用於與該骨互鎖。該齒狀物 係可具有一角錐形或鋸齒形狀。 爲了將該端構件固定於植入物上,該第二部分係可具 有一個用於容納一扣件的孔洞。或者,該第二部分的外側 表面係可具有突起,其係被按尺寸製造以可插入該植入物 的孔穴內。在一個示範的實施例中,該第二部分係包含有 複數的垂片將該端構件固定至該植入物上。該等垂片係具 有彈性,以使得該等垂片向內彎曲而使該第二部分插入植 入物內,且彎曲恢復向外以產生摩擦配合而將該端構件固 定於該植入物土。另一個實施例中,該端構件係包含有一 個突出物,其係被鉸接或是樞軸地連接至該第一部分、一 6 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) --------------------訂---------線 (請先閱讀背面之注意事項再填寫本頁) 519488 經濟部智慧財產局員工消費合作社印製 B7 五、發明說明(4 ) 螺紋孔係位在該第二部分’及一可插入該螺紋孔之固疋螺 釘。將該固定螺釘穿過該孔洞’引起該突出物之向外移動 ,因而可將該端構件固定於該植入物。 在一替代的實施例中,根據本發明之一端構件係包含 有一頂面及一套筒,該頂面係與該骨的大小及形狀一致’ 而該套筒係由頂面延伸出來且其形狀及尺寸係可容納該植 入物之一端部。該端構件又包含有第一及第二部分’其係 可樞轉的介於一開啓位置及一閉合位置之間’其中該開啓 位置係用以促使該套筒容納該植入物的端部’而關閉位置 係用以將該端構件固定至該植入物。一鎖合元件係將該端 構件固定於該閉合位置。 在另一個替代的實施例中,該端構件係包含有一個外 環及一個內環,該外環係有一具斜面之尖叉,而該內環係 可相對於該外環而轉動。該內環係具有一個突起,在轉動 時該突起係與該尖叉的斜面相接觸,因而徑向地向外推進 該該尖叉。 【圖式簡要說明】 本發明之較佳的特色係揭示於伴隨的圖式中,其中在 所有的視圖中,相同的參考圖號係表示相同的元件,且其 中: 圖1係顯示根據本發明之一端構件的一第一個實施例 之透視圖; 圖2係顯示於圖1之端構件插入一圓柱的網狀入物 之側視圖; 7 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公爱) (請先閱讀背面之注意事項再填寫本頁) 訂-------線一 519488 A7 B7 五、發明說明(5) 圖3係顯示具有橢圓形之端構件的透視圖; 圖4a係顯示一端構件之透視圖,其中該端構件係具 有橢圓形狀及用以增進植入物之穩定性的齒狀物; 圖4b係顯示一端構件之透視圖,其中該端構件係具 有第一及第二通道以促進與移植工具使用; 圖4c係顯不一端構件之另一*個實施例的透視圖,其 中該端構件係具有第一及第二通道; 圖5係顯示具有一個楔形外觀之端構件的側視圖; 圖6係顯示一具有突出物之端構件的透視圖,其中該 突出物係用以固定至該植入物; 圖7係顯不一非環形端構件的透視圖; 圖8係顯示根據本發明之一端構件之底部的透視圖; 圖9係顯示根據本發明之一端構件之底部的透視圖; 圖10係顯不根據本發明之端構件之另一個實施例的 俯視圖; 圖11係顯示圖10中之端構件的橫剖視圖; 圖12係顯示根據本發明之端構件之另一個實施例的 俯視圖; 圖13係藏不將圖12中之端構件固定至一圓柱的網狀 植入物;及 圖14係顯不根據本發明之端構件之另一個實施例的 橫剖視圖。 【元件符號說明】 10 端構件 8 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) (請先閱讀背面之注意事項再填寫本頁) 訂一--------線< 經濟部智慧財產局員工消費合作社印製 519488 A7 B7 五、發明說明(J ) (請先閱讀背面之注意事項再填寫本頁) 12 第一部分 14 第二部分 16肩部 18 頂面 20 第一通道 21第二通道 22 骨融合植入物 24 孔洞 26 縫隙 27 縱軸線 28 突出物 30 環狀空間 32 齒狀物 3 4 第一端部 3 6 第二端部 40 垂片 81 套筒 經濟部智慧財產局員工消費合作社印製 110、210 端構件 212、214 端構件 310, 410, 510, 610, 710, 810 端構件 812 頂面 814 套筒 8 1 6 第—r部分 818 第二部分 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) 519488
五、發明說明(y ) ’該第二部分14的形狀與具有該端構件的骨融合植入物 的开:^狀相配合。如圖2之最佳顯示,第二部分14係按尺 寸製作及塑造以被插入一個骨融合植入物22的內孔中, 以使得肩16係依靠在骨融合植入物22上。骨融合植入物 22係可具有許多種不同的移植型態,例如,其包含有一網 狀植入物、一同種異體植入物、或者是任何一種金屬或非 金屬的植入物。如果植入物22係爲一種金屬材料製品, 端構件10較佳地係爲相同的金屬所製成,或者是由一種 非金屬的材料所製成以避免摻雜金屬(電流)侵蝕。端構 件10亦可由同種異體移植骨所製成,其係來自鬆質骨、 緻密骨、一種鬆質骨與緻密骨之組合、或是鬆質骨與緻密 骨的合成物。在端構件1〇及骨融合植入物22的移植之後 ’生理的壓縮力量將易於使端構件10固持在一相對於骨 融合植入物22之適當位置。然而,爲了提供更佳的穩定 性及幫助手術前及手術期間的處理,第二部分14係可被 固定在骨融合植入物22。例如,第二部分Η係可被壓入 配合或扣入配合至骨融合植入物22內。此外,由於骨融 合植入物22係典型地爲可變形的,所以骨融合植入物22 係可被捲曲至端構件10。第二部分14亦可提供有一個孔 洞24以用於容納一個扣件,例如栓或是螺釘。端構件1〇 係被插入骨融合植入物22,以使孔洞24可與骨融合植入 物22上之一縫隙26排成一直線。孔洞24係可部分地或 是完全地穿過第二部分14,且係可具有螺紋。如圖6所示 ,第二部分14替代地係可具有突出物28,該突出物28係 11 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) (請先閱讀背面之注意事項再填寫本頁) 訂P--------線一 經濟部智慧財產局員工消費合作社印製 519488 經濟部智慧財產局員工消費合作社印製 A7 B7 五、發明說明(y ) 按尺寸製作以可配合縫隙26 ’以用於將該端構件機械地固 定至骨融合植入物。其他用於將該端構件固定至骨融合植 入物之示範機構,將於以下被更詳細地說明。 關於前面之圖1及圖2中,頂面18之表面積係大於 骨融合植入物22的頂面及底面之表面積。由於該較大的 表面積,在頂面18及其周圍的骨之間的接觸面積係大於 該植入物22之頂面及底面的接觸面積。接觸面積的增加 係可幫助抵抗植入物22的下陷。該增加的接觸面積係具 有其他的優點’例如在端構件1 〇與其周圍的骨之間的有 更佳的負荷分佈。如圖所示,頂面18係爲一具有一環狀 空間30的環形物。新骨係能在環狀空間30中形成以促進 融合。環狀空間係可被塡滿骨碎片或是任何其他的骨誘導 或是骨傳導之材料,以促進骨的形成。 替代地,如圖7所示,頂面18係可爲一實心的表面 ,以使介於頂面18及其周圍的骨間的接觸面積爲最大。 在一特別地擔心下陷之臨床狀況中,一實心的頂面18將 是令人滿意的。 圖3係顯示根據本發明之一端構件110的第二個實施 例。一般而言,端構件Π0 (如以下所述之實施例)之大 部分的架構係相似或可媲美於端構件10的架構,且,因 而使用相同的參考符號表示相似的元件,且該相似元件的 討論係被認爲是不需要的。端構件no係具有一個橢圓形 或長橢圓形狀,,且其將被使用於當該周圍的骨(且因而該 骨融合植入物)係實質地爲橢圓形或長橢圓形之情況中。 12 ------------P衣--------訂:—-----線· (請先閱讀背面之注意事項再填寫本頁) 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) 519488 經濟部智慧財產局員工消費合作社印製 A7 ___B7_______ 五、發明說明(p ) 當該端構件係具有一非對稱之形狀’如端構件11 〇,該第 一通道20係可能被提供於任何方向上。例如,第一通道 20係顯示沿著端構件110之長軸穿通,但可在任意方向穿 通以相對於該周圍的骨而定向於不同之方向。第一通道20 之設置的變化性意謂著第一通道20係可被放置於儘量適 合於該被使用之特殊的外科手術的路線。具體而言,若端 構件110係沿著該短軸之前面/後面的方向被植入,則第 一通道20係非常適合用於一個側向的外科路線。若預先 考慮一前面或後面的路線,則第一通道20應可沿著該前 面偏後的方向穿通。 圖4a係顯示一個具有第一通道20的端構件210,其 中該第一通道20係以相對於該端構件210之長軸有一個 夾角的方向穿通。此第一通道20的方向較佳地係用於一 前面偏側的外科手術路線,該外科手術路線係可被使用於 脊髓的外科手術中。圖4b係顯示一個端構件212,該端構 件212係包含有第一通道20及第二通道21,該兩通道皆 係以相對於該端構件212之長軸有一個夾角的方向穿通。 較佳地,第一及第二通道20、21係相對於端構件212的 長軸而對稱地設置。在移植手術過程中,不論該前面偏側 的外科手術路線是使用左邊或右邊,該具有第一及第二通 道20、21之端構件212的設置係可允許該第一及第二通 道20、21之至少一者可通過。而且,通道20、21的安排 係可容許一個端構件被使用於骨融合植入物的每一個端部 ’而仍然可使該端構件的頂面之通道對齊該端構件的底面 13 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) ------------0^--------訂*---------線· (請先閱讀背面之注意事項再填寫本頁) 519488 A7 B7
五、發明說明((丨) 經濟部智慧財產局員工消費合作社印製 之通道。圖4c係顯示一個端構件214,該端構件2U亦包 括有第一及第二通道20、21。第一通道20沿著平行於端 構件2H之長軸方向穿通,而第二通道21係橫向地穿通 該端構件214之長軸方向。不論端構件214的移植方向或 是外科路線爲何,該包含有第一及第二通道20、21的端 構件214係可提供通到第一及第二通道20、21之至少〜 個通路。 如圖4a、4b、及4c中所顯示的每一個端構件,其頂 面18具有複數齒狀物32,該等齒狀物係可在該端構件與 周圍骨之間提供機械性的連結。齒狀物32係藉由刺入該 骨以提供機械性的連結。藉由該齒狀物32所提供之初始 的機械穩定性係使在手術後將該端構件的拔出或排除的危 險降至最小。齒狀物32係可具有任何適當的外形,例如 角錐形、鋸齒形等。替代地,頂面18係可具有紋理,以 在該端構件與其周圍骨之間提供機械性的連結。 如圖5所示,一端構件310係具有一楔形外觀。在脊 髓之應用方面,爲了恢復脊髓或任何骨的自然曲率,一楔 形的外觀係爲有利的。一楔形的外觀亦可用於補償一由病 理學、臨床狀態、或是錯誤地移除骨之命令切割的非正交 的切骨手術。需注意的是,當一端構件係通常地被使用於 骨融合移入物的每一個端部時,具有不同楔形外觀的端構 件係可被一起使用。一個達成此楔形之效果的方法爲,於 第一部分12上,從第一端部34到第二端部36之間的厚 度逐漸遞減,以使得頂面18形成α角所定義的一個斜度 14 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) -------------參--------訂·!線鋤 (請先閱讀背面之注意事項再填寫本頁) 經濟部智慧財產局員工消費合作社印製 519488 A7 B7 五、發明說明(α) 。在圖5中所示,頂面18爲一個平坦的表面。然而’頂 面18係可爲一彎曲的表面且仍然保留該楔形外觀。由於 能夠使得該彎曲製成一脊椎端板之地形的鏡像’則一彎曲 的頂面18將符合該脊椎端板的輪廓。 如前面所述,圖6係顯示一具有突出物28之端構件 410,該突出物28係按尺寸製作以配合骨融合植入物22 ( 如圖2所示)的縫隙26。圖7中,亦如前述,係顯示一具 有一實心頂面18的端構件510,該實心頂面18較佳地係 使用於當具有較高的下陷發生率時。 圖8係顯示一具一第二部分14的端構件610,該第二 部分I4係包含許多的垂片40以用於將端構件610固定至 骨融合植入物22。在一實施例中,垂片40係富有彈性的 ,以使得當端構件610的第二部分14被推入骨融合植入 物時’垂片40係向內彎曲,然後向外回復以將端構件610 固定於骨融合植入物22上。當骨融合植入物22具有稍許 彈性時’其係可容許該植入物22向外彎曲以接受垂片40 ’垂片40係不需具有彈性。垂片40的數量、大小、及排 列係爲可變化的。圖9係顯示一端構件710,除了整個形 狀的改變外(從圓形改變爲橢圓形或長橢圓形),該端構 件710係相似於端構件610。 圖及11係顯示一具有其它機構的端構件810,該 等機構係用於將端構件810固定於骨融合植入物22上。 具體而言,端構件810係爲一置放在植入物22頂部的蓋 子。端構件810係包含有一頂面812,該頂面812係與骨 15 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) ------------费--------訂:——'-----線· (請先閱讀背面之注意事項再填寫本頁) 519488 A7
