Description
玟、發明說明: 1項引文的一種骨髓内骨 的脛骨者。 【發明所屬之技術領域】’ 本發明關於申請專利範圍第 懸針,特别用於遠體端(distal) 【先前技術】 交的二已有一些標記骨釘在相同高度具有二個相 :孔’俾使同—種骨髓釘可用於右邊及左邊的管形骨。 k種習知裝置的缺點在於:該二個(或數個)孔相交 二:軸交點在針縱軸上,因此要將較多的材料從骨髓釘 截面除去,這點使得該骨髓釘在此位置的機械 大減低。 【發明内容】 一對此本發明提出對策。本發明的目的在提供一種具有 :個:或數個)相交又之橫孔的骨髓釘,e比起先前技術 來有較佳的機械強度,而不須為此將橫截面積加大。 本發明係利用具有申請專利範圍第i項的特點的一種 骨髓釘達到此目的。 種變更方式係在於,該二個貫穿的孔圓筒形的圓筒 轴在交點P相交,該交點距縱軸距離d > 0,此距離d相 對於月骑針的直徑D的關係係在以下範圍中:0.0001D< d < 0.6000D,且宜 〇 2D< d< o 5D。 另種變更方式在於:該二個貫穿的孔圓筒形的圓筒 轴係為歪斜(windschief’英:者,且具有該長度 x>0的最短距離。在此’該長度X要小於該貫穿之孔圓筒 开y的—個直也的和一半,俾使該二個孔圓筒形會貫穿。在 1321045 該二個歪斜的圓筒軸之間的長度x的段落s(它構成最短 的距離)可平行於該縱軸或對縱軸成歪斜延伸,且在一最 短距離γ>0。在此,該距離y宜小於d/2但大於〇.4D。 在另-實施例t ’該二個貫穿的孔圓筒形的圓筒軸係 位在一個與縱軸正交的平面中。反之,在另—實施例中, 該二個貫穿的孔圓筒形的圓筒軸係在一平面中,該平面被 縱軸以一角度α通過,其中〇。< α <6〇。,且宜〇。〈 α < °。這種歪斜設置優於正交設置之處在於該要放入孔圓 筒形中的螺絲的倚靠長度要長得多,這點使穩定性提高。 另一優點在於對骨折的供養更佳。 在另一實施例中,該貫穿的孔圓筒形以一角度石相交 ,其中30Ή90。,且宜5〇。〈点<8〇。。最佳的角度 選擇可使壁厚度最佳化。 在一較佳實施例中,該二個貫穿的孔圓筒形有二條分 J的入路進入骨髓釘’但只有一條共同的出路從該骨髓釘 出來。這種設計優於四個開口的設計之處為:材料挖除量 可儘篁小,故骨髓釘有較大強度。 5亥貫穿孔圓筒形的直徑DB最多宜為D & 0.6倍,且 且為最多0.5倍。 另實施例中,該骨髓釘有一個對中心縱軸成共軸 的縱孔。此空心針狀的直徑相對於孔圓筒部的直徑的比越 則該貫穿之橫孔越可互相成一角度,而不會影響骨髓 、丁的橫截面積,換而之不會減少骨髓釘的強度。 本七明與本發明的進一步特點在以下利用數個實施例 的部分示意圖式詳細說明。 1321045 【實施方式】 第1〜第3圖所示的趙内骨髓釘(1)有一遠體端(?)、一 近體端(3)、K縱軸(4),及二橫孔⑺,該遠體端⑺適 用於放入一管骨的標記空間中,該二橫孔(5)具有一孔軸(6) 且各定義出一虛擬的孔圓筒形(8),該孔圓筒形有一圓筒軸 (9),與該定義的橫孔(5)的孔軸(6)對應。該骨鶴釘有二大 致恆定的直徑D,以及與中心縱軸(4)成共軸的縱孔(1〇)。 如第3圖所示,該二個橫孔(5)的孔圓筒形互相從反側 貫穿’其中該二個貫穿的孔圓筒形(8)的孔圓筒軸(9)在點p 相交,該點P距縱軸(4)的距離d==〇4D。換言之,該點p 不在骨髓釘的縱軸(4)上。 該貫穿之孔圓筒形(8)有二條分別的進路進到骨髓釘⑴ 中,但只有一條共同出路從該骨题釘(1)出來。該二個貫穿 的孔圓筒形⑻的圓筒軸(9)位在—個與縱轴⑷正交的平面 中,該平面對應於…的圖面。但該二個貫穿的孔圓筒 形(8)的圓简軸(9)也可在另一平面φ ^ 面中’此平面被縱軸(4)以 一定的角度α通過(第2圖)。 在圖示之實施例中,該-徊+也 ±χ/ Τ忑一個貝穿的孔圓筒形(8)的圓筒 軸(9)以一角度冷=60。相交。 该貫穿的孔圓筒形(8)的直和D + W』且仫,在此圖示之例子中 係為D的0.3倍。 如第4圖所示,在另—眚 饩#,〇、 貫轭例中,該二個貫穿的孔圓 间形(8)的圓筒軸(9)也呈歪钭方、儿从 χ μ ’乜至企斜方式沿伸’且具有該-定長度 χ的最短距離(11),該長度 栌 茛皮j於該貝穿之孔圓筒形(8)的直 ^的和的一半。該二條
