Description

經濟部智慧財產局員工消费合作社印製 A7 _________B7_ 五、發明説明(f ) " — -- 〔詳細說明〕 本發明關於一種依申請專利範圍第1項之引文的_種 固定裝置’它係用於將外科植入物,外科縫線或布(,組織 )固定在骨中或骨上者。 ^ 在非醫學領域已有一些習知之封口鉚釘(封 (Blindniete) ’其封閉頭由分別之舌片(它們張開得相對地 寬)構成。舉例而言,這種封口鉚釘發表於美專利 US4,696,610 (Wright)及 US4,580,936 (Frands)。這些習知鉚 釘有縱走的槽孔或切槽,它們在封口鉚釘封閉(_合)時 ,可使由分別之舌片構成的封閉頭形成,如此所形成之封 閉頭有大的倚靠面積。這種習知之封口鉚釘的缺點胃:該 封閉頭利用縱走之舌片折彎(Knick)形成,因此舌片末端並 不能呈利齒方式壓入該在封閉頭側所要連接的材料中,以 防止封口鉚釘在所要連接之材料的孔中轉動。 在英專利 GB 2054082 (Tucker Fasteners)發表了另一種 非醫用的封口鉚釘,但它有一圓形通過開口,因此不能防 止轉動。 本發明對此提出對策,本發明的目的在提供一種固定 系統,它可通過一小孔放入,且在固定後,由於錨固舌片 張開,故在骨內面上有寬的支持部,其中該錨固舌片可埋 入骨內面中,因此可防止封口鉚釘轉動。 在醫用範圍,本發明的固定元件差不多可用所有在今 日骨螺絲使用之骨折處理的方面,特別是: ——在疏鬆的骨〔它有一部分只有一層很薄的皮質 本紙張尺度適用中國國家標準(CNS > A4規格(210X 2971公釐) ---------^------ΐτ------線. (請先閱讀背面之注意事項再填寫本頁) A7 B7 五、發明説明(>) (KomkaUs)〕,本發明的固定元件可用在螺絲的位置 以作骨板固定: 在鬆質骨(Spongiosa)中,本發明的固定元件可當作骨板 或縫線的錨,或將筋(Sehnen)及韌帶(Band)做再固定, 在封口鉚釘之封閉頭張開時形的爪(Krallen)突出來而 錨固在該鬆質骨的小桁構造中;且 一一在關節頭中,如,脛頭或肱頭,本發明的固定元件可 當作側板或骨髓內(intramedullar)載體的錨固件之用。 目前縱載體的錨固係利用大螺絲。但這種螺絲在關節 頭的疏鬆骨中不能提供最佳的錨固作用。 類似的系統具有可釋放的爪的螺絲,標記釘或髖螺絲 ’例如肱骨用的杯狀標記釘(Seidel-Marknagel)。這種標記 釘在釘尖端上有槽孔,槽孔被具球頭的一根中央銷脹開。 如此,舌片呈翼狀向外彎曲。而這些舌片只略從該釘彎了 —角度。 這種習知固定手段的缺點爲:利用這種習知之固定手 段迄今仍不能將植入物錨固在疏鬆的骨中。往往’ 一種植 入物只能藉著把骨水泥灌入骨中而固定。這—點問題很多 ,因爲骨水泥硬化時,骨會受產生之熱損壞。此外’該骨 水泥不能再拿掉,否則可能會發生感染。 這種習知固定手段另一缺點爲:保持力量(例如一枚 螺絲的保持力量)係利用其直徑造成。當沿軸向受過度負 荷時,則有一個圓筒形骨體(其直徑等於螺絲直徑)撕裂 出來。在健康的骨的場合’骨螺絲的保持力量係足夠者。 _ S _ 本紙張尺度適用中國國家標準(CNS ) A4規格(210X297公釐) ---------批衣— (請先閱讀背面之注意事項再填寫本頁) -V3 線 經濟部智慧財產局員工消費合作社印製 A7 B7 五 、發明説明( 在同質疏鬆症(Osteoporose)的場合’在關節區域或在細的殼 狀与的場合’螺絲固定往往不足。較大的螺絲會因空間理 由不能使用,或另外造成對尙存之骨的損壞。 對此本發明提出對策。本發明之另一目的在提供 固定系統,它可經過一小孔放入且在固定後,由於錯固舌 片張開,故在骨內面有寬的支持部。 本發明解決上述問題之道,係利用具有申請專利範s 第1項之特點的固定裝置(它用於將外科植入物、外科_ 線或布固定在骨中或骨上)。 在封閉部上封口鉚釘中的通過開口具有多角形之;|:黃_ 面,它宜爲方形,但也可爲三角形、五角形、六角形或更 多角之形。 本發明之用於將外科植入物、外科縫線或布固定 中或骨上的固定裝置的一較佳實施例由一封口鉚釘(它胃 一縱與一共軸的通過開口)以及一個可放入該通過開d中 的封閉元件構成。封閉元件在其長度的範圍至少在一個_ 到其後端的部分具有多角形橫截面,其中,在其長度範圍 中的此部分上,這種橫截面沿縱軸向封閉元件之後端變寶; ,封閉元件放入封口鉚釘中,使得封閉元件之錐形部的較 小橫截面先一直放入封口鉚釘中直到它由於橫截面漸大而 卡在封口鉚釘之通過開口中爲止。當把封閉元件進一步職 入封口鉚釘之通過開口中而將封口鉚釘封閉時,該封 釘在此要封閉的部分上受到該封閉元件之變寬的部份分成 分別的錨固舌片,該錨固舌片遂受到封閉兀件之變寬部分 _________^________ 度適用中國國家揉準(CNsTAi格(210X297公釐)_ ^ ---------抽衣------訂------線 (請先閱讀背面之注意亨114¾^本頁j 經濟部智慧財產局員工消費合作社印製 B7 經濟部智慧財產局員工消費合作社印製 五、發明説明(斗) 脹開成半圓形,並構成一個封閉頭,該封閉頭錨固在一個 大面積上,且由多數錨固舌片構成。在此,錨固舌片的數 目相當於封閉元件之多角形橫截面的邊數。 本發明其他有利的特點見於申請專利範圍附屬項。 本發明裝置的另一實施例與前述實施例不同之處在於 :該封閉元件至少在其長度範圍的一個接到其後端的部分 具有方形橫截面。橫截面的邊緣數較少的優點爲其邊緣較 銳’如此在封口鉚釘封閉時,有利於鉚釘軸桿分成分別的 錨固舌片。 本發明裝置的又一實施例與前述各實施例不同處在於 :封閉元件的橫截面在少在其長度範圍的一個接到後端的 部分沿著縱軸向封閉元件的後端呈錐形變寬,其中該錐形 角度設定成有利於使鉚釘軸桿分成分別的錨固舌片,以及 在封口鉚釘封閉時使錨固舌片張開。 本發明裝置的再一實施例與上述各實施例不同處在於 :在封閉部分上在封口鉚釘中的通過開口具有方形橫截面 ,且在角落在鉚釘軸桿中設有預定斷裂位置,如此有利於 封口鉚釘封閉時,鉚釘軸桿分成分別的鉚固舌片。這些預 定斷裂位置的壁厚度宜爲封口鉚釘外直徑(D)的1%〜10%間 ,且宜在5%〜9%間。 本發明裝置另一個實施例與前述各實施例不同處只在 於:封閉元件與一_閉銷連接成可鬆開的方式。 此外,本發明裝置另一實施例與上述各實施例不同處 在於,至少一封閉元件爲一標記釘的一部分。 _ 7 本紙垠尺度適用中國國家梯準(CNS ) A4規格(210X297公釐) 餐#------^ (請先閲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 A7 ____B7 五、發明説明(S ) " ' 此外,本發明裝置又一實施例與上述各實施例不同處 在於:該封口鉚釘有一可鬆開的鉚釘頭。爲此,該可鬆開 之鉚釘頭設有一個內螺紋,它可旋合到封口鉚釘的一對應 之外螺紋上。如果封口鉚釘當作錨固件使用(例如隨一側 板或一標記釘用在股骨頭中當作固定手段)或當作線錨固 件用,則不具鉚釘頭的封口鉚釘類型較適用。在此,這種 無鉚釘頭之封口鉚釘類型的優點爲,在脹開過程時,可沒 入骨中更深。這種「後滑動作用」防止在封口鉚釘脹開時 ,鬆質骨切斷的情事。 此外,本發明裝置再一實施例與上述各實施例不同處 在於:在封閉元件後端上設一鑽頭尖,藉此可將骨預先鑽 孔。 另外,本發明裝置另一實施例與前述各實施例不同處 在於:在封口鉚釘中的通過開口在其長度範圍的一部分〔 此部分與所要封閉的部分對立〕設有一內螺紋,舉例而言 ,它可使其他植入物或植入物部分旋入該安裝之封口鉚釘 中。 另外,本發明裝置又一實施例與前述各實施例不同處 在於:該封閉元件之封閉銷可作彈性彎曲。如此,舉例而 言,可使封口鉚釘裝在股骨之頭部中,其中,封閉銷可穿 過整個股骨之頭部過去。 另外,本發明裝置再一實施例之特點爲:在封口鉚釘 之所要封閉的部分的壁厚s爲封口鉚釘之外直徑的1%〜 20%之間。如此,可使鉚釘軸桿利用封閉元件上的多角錐 ---------^------II------^ (請先閱讀背面之注意事項再填寫本頁) 1紙液尺度適用中國國家準(CNS ) A4規格(210X297^釐) " A7 B7 經濟部智慧財產局員X消費合作社印製 五、發明説明(fc ) 形簡單地張開成分別的錨固元件。 此外,本發明裝置另一實施例之特點在於:該錯固元; 件可利用封閉元件相對於縱軸呈半圓形脹開,且構成封口 鉚釘的封閉頭。如此,舉例而言,在骨內面上造成寬的支 持部,且由於該錨固舌片之半圓形設計使錨固舌片的末端 幾平垂直豎立在骨面上,故封閉頭有爪式的錨固作用。 此外,本發明裝置又一實施例不同於前述各實施例的 特點在於:該封口鉚釘由一種可呈可塑性彎曲的材料(例 如純鈦、鈦合金或植入物鋼)構成,如此可促成上述半圓 形錨固舌片的設計。 此外,本發明裝置又一實施例與上述各實施例不同處 在於:在封閉頭的二個相對立之錨固舌片的二個對立端之 間夾了一段長度(L),相當於封口鉚釘直徑(D)的二倍到三 倍。這種錨固舌片這種大幅的張開造成骨面上寬潤的支持 部。 利用本發明所達成的優點主要在於:由於拜本發明的 裝置之賜’只須在骨中鑽一小孔,且本發明的封口鉚釘在 安裝後’在骨內面上有寬的支持部。此外,舉例而言,和 在髖螺絲的情形不同,由於錨固舌片呈半圓形錨狀設計以 及錨固在骨中,故可阻止固定手段的頭部轉動的情事。此 外,在疏鬆的骨的情形’如果關節頭中還有鬆質骨,也不 會受機械性負荷。換言之,如果髖螺絲係在一空腔中,這 點是會使髖頭相對於髖螺絲錯位。只有當髖螺絲已與骨內 面接觸時,髖螺絲才會發揮其作用。由於在此情形中,螺 本紙張尺度適用中國國家標準(CNS ) A4itJt格(210Χ29_7^^~ I------ΐτ------^ (請先閲讀背面之注意事項-^i.寫本頁) 經濟部智慧財產局員工消費合作社印製 A7 _________B7 五、發明説明(q ) 絲與骨之間的界面往往不足。故會使螺絲穿入髖關節中。 在具有半圓形錨固舌片的本發明之封口鉚釘的場合,最初 利用骨內面當作植入物與骨間的界面。利用錨固舌片這種 良好配合解剖學構造的形狀,該對骨之接觸面可更大且更 佳地配合。如果使用本發明之封口鉚釘來將一標記釘錨固 在股骨頭中,則只要鑽約8画的孔來容納本發明的封口鉚 釘。這點的好處爲,該標記釘的直徑比起既有之標記釘髖 螺絲系統來,可大大地減少。 本發明本身與本發明的進一步發展在以下利用數個實 施例的部分示意圖的圖式詳細說明。 圖式中: 第一圖係經本發明封口鉚釘一實施例及本發明封閉元 件之一實施例的縱剖面圖, 第二圖係經本發明封口鉚釘一實施例及本發明封閉元 件另一實施例的縱剖面圖, 第三圖係經本發明封閉元件在第二圖中所示實施例的 一橫剖面圖, 第四圖係經一封閉之本發明封口鉚釘的一實施例的縱 剖面圖,它具有一骨板及一骨件, 第五圖係一封閉之本發明封口鉚釘在第四圖中所示之 實施例的視圖, 第六圖係經本發明封口鉚釘另一實施例的一縱剖面圖 j 第七圖係本發明封口鉚釘在第六圖所示實施例之前視 本紙張尺度適用中國國家標準(CNS ) Α4規格(210X297公釐) ---------1------ΐτ------線· (請先閱讀背面之注意事項再填寫本頁) A7 B7 五、發明説明u ) 圖, 第八圖係經本發明封口鉚釘另一實k例的縱剖面圖’ 第九圖係經本發明封口鉚釘另一實施例及本發明封閉 元件之另一實施例的縱剖面圖’ 第十圖係本發明封口鉚釘在第九圖中所示實施例及第 九圖中所示本發明之封閉元件的前視圖’ 第十一圖係經一股骨的縱剖面圖,它具有一本發明的 封口鉚釘、一個標記釘及一安裝匣。 -- (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髮 〔圖號說明〕 ⑴ 封口鉚釘 ⑵ 封閉元件 (3) 縱軸 (4) 通過開口 (5) 多角形橫截面 (7) 所要封閉的部分 (8) 鉚釘軸桿 (12) (封閉元件的)後端 (13) 錨固舌片 (15) (通過開口)的角 (16)(17) 封閉銷 (18) 標記釘 (19) 鉚釘頭 (20) 鉚釘頭 (21) 鑽孔尖端 、-'° 本紙張尺度適用中國國家標準(CNS ) A4規格(210X297公釐) 五、發明説明(γ ) Α7 Β7 (23) 外螺紋 (24) 內螺紋 (25) 骨板 (26) 骨 (27) 外螺紋 (28) 內螺紋 (29) 股骨 (30) 匣 (31) (錨固舌片的)末端 (32) 遠體端(前端) ί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杜印製 第一圖中顯示依本發明裝置之一實施例的一個封口鉚 釘⑴及一封閉元件(2)。封口鉚釘⑴有一縱軸(3),且由一 圓筒形鉚釘軸桿(8)〔它平行於縱軸(3)延伸,但不一定要爲 圓筒形〕、一鉚釘頭(19)〔它與鉚釘軸桿(8)連接〕與一圓 筒形通過開口(4)〔它沿縱軸(3)呈共軸貫穿過封口鉚釘(1)〕 構成。鉚釘軸桿⑻有一直徑(D),因此,由通過開口⑷之 寬度及外直徑(D)所定之壁厚大小之量使得封口鉚釘(1)用封 閉元件(2)封閉(鉚合)時,封口鉚釘(1)可在所要封閉的部 分(7)上分離成分別的錨固舌片(13)(第四、五圖),其中 ,錨固舌片(13)的數目相當於封閉元件(2)的多角形橫截面 的邊的數目(第三圖)。在此處所示之封口鉚釘(1)的實施 例中,鉚釘軸桿(8)的壁厚s相當於外直徑(D)的14%。在本 發明裝置第~圖中所示之實施例中,封閉元件(2)係爲一封 閉銷(16)的構件。封閉元件(2)在其長度範圍的一部分〔此 12 -a 本紙張尺度適用中國國家標準(CNS ) Μ規格(210X297公釐) 經濟部智慧財產局員工消費合作社印製 A7 -----_____ B7 五、發明説明(fC) 部分接到其後端(12)〕上具有多角形橫截面(5),向後端(12) 變寬(第三圖)。封口鉚釘(1)在放入後,利用封閉元件(2) 封閉,封閉兀件(2)利用一股作用到封閉銷(丨6)上的拉力壓 入封口鉚釘(1)之所要封閉的部分(9)中。當封閉元件(2)之變 寬的多角形部分壓入時’鉚釘軸桿(8)的壁脹開,並被該多 角形橫截面(5)的邊(第三圖)分成錨固舌片(π)(第四圖 與第五圖)。封閉銷(16)可利用一預定斷裂位置與封閉元 件(2)連接,如此該封閉銷(16)在封口鉚釘(1)封閉後,舉例 而言,可施以扭轉力而封閉元件(2)斷離。 第二圖中所示之本發明實施例與第一圖中所示實施例 不同處只在於:封閉元件(2)有一內螺紋(24),與縱軸(3)成 共軸延伸,且封閉銷(17)有對應之外螺紋(23),如此’該設 計成分別之元件的形式的封閉銷(丨7)可以用可鬆開的方式 旋合到封閉元件(2)中。在鉚釘⑴封閉後’封閉銷(17)可封 閉元件(2)旋離出來,因此從封閉的封口鉚釘(1)分離。 第三圖顯示垂直於縱軸(3)經封閉元件⑵的—剖面圖。 在此處所示之本發明裝置實施例中,該多角形橫截面(5)由 —方形橫截面構成,如此,在封口鉚釘(1)封閉時,形成四 個錨固舌片(13)。第三圖中同樣地顯示在第二圖中所示本 發明裝置之實施例的封閉元件(2)的內螺紋(24) ° 第四圖顯示經本發明裝置一實施例之一封閉的封口鉚 釘的縱剖面圖,封口鉚釘(1)把—骨板(25)與一骨(26)連接。 封閉頭(14)包含四個鉚固舌片(13),其末端(31)含盍了長度 (L)。由此圖也可看出,被麵舌片(13)之末端(31)所含蓋的 _____13 --------- 氏張尺度適用中國國家標準(CNS ) A4規格(210X297公釐) (請先閱讀背面之注意事項再填寫本頁)
