Description

骨骼或脊椎動態穩定用之屈曲性穩定裝置
本發明係關於骨骼或脊椎動態穩定用之屈曲性穩定裝置，此裝置包括彈料性材料製之桿構造。
相鄰脊椎穩定用之屈曲性穩定裝置，已載於EP 0 669 109 B1。在此穩定裝置中，置於相鄰脊椎的單軸骨釘，利用彈性帶相連接。此帶以預力方式繫止於骨釘。抗壓縮之支持體，包圍骨釘間之帶，以傳輸壓縮力。支持體、骨釘頭和彈性帶形成一種接頭，使脊椎可有限運動。
US 2003/0220643 A1揭示一種相鄰脊椎體之連接裝置，其中單軸梗釘利用彈簧連接。彈簧使脊柱可屈曲，可有限度的側彎和軸向轉動，同時防止脊柱延伸，不需用橫向構件。套筒置於彈簧上方。套筒和梗釘間之衝擊，有助於彈簧防止脊椎延伸。彈簧長度先預定。不可能由外科醫師適應長度。
WO 2004/105577 A2揭示一種脊柱穩定系統，具備一或以上之屈曲性元件，有開孔或細縫，呈螺旋圖型之形狀。在手術中，系就無法就其屈曲性特性加以調節。
EP 1 364 622 A2記載一種骨骼固定裝置，包括單軸骨釘和屈曲性桿。骨骼固定裝置之彈性特性，是由外科醫師無法加以改變的桿材料和形狀所決定。此外，使用單軸骨釘限制了軸相對於桿的位置調節之可能性。
本發明之目的，在於提供一種骨骼或脊椎動態穩定用之屈曲性穩定裝置，得以改變裝置之彈性特性，同時在手術當中可適應桿構造的長度。
此目的是以申請專利範圍第1項之骨骼固定裝置解決。進一步發展則列於申請專利範圍附屬項。
由內桿和外桿或彈料性材料製套筒構成的屈曲性桿構造，得以調節穩定裝置的彈料特性至很大程度。藉選擇具有彼此不同的適當彈性性能之桿和套筒，即可令桿構造的彈性性能適應特殊脊柱段之運動。尤其是脊柱的屈曲和壓縮，可利用內桿的彈性性能加以控制，而脊柱的延伸可藉選擇適當套筒加以控制。關於屈曲/壓縮和延伸運動之阻尼加以分離，造成脊椎段在構造的運動控制下的合諧行為。結果，可防止骨釘的鬆弛。另一優點是可調節內桿和套筒之長度。因此，提供模組系統，可在手術時間調適。再加上多軸釘，可更加調高調節之可能性。
本發明其他特點和優點，參見附圖所示具體例之詳述，即可顯而易知且最能明白。
如第1a和1b圖所示，屈曲性穩定裝置包括桿構造，含有彈料性材料製的桿20，也是彈料性材料製的套筒40。在圖示具體例中，桿20為圓筒形狀，有光滑表面。由於彈料材料之故，桿是部份或全然屈曲性。例如，桿20由生理相容性塑膠材料製成，諸如以聚胺酯、聚矽氧或PEEK為本之聚合物。特別適用材料為聚碳酸酯胺酯。桿的材料包括充分界定之彈性性能，而桿顯示彎曲彈性、壓縮彈性和拉力彈性。
套筒40之彈料性材料亦為生理相容性塑膠材料，諸如以聚胺酯、聚矽氧或PEEK為本之聚合物，包括彈性性能，可獨立於桿20的彈性性能加以選擇。對套筒而言，也是以聚碳酸酯胺酯特別適用。套筒40呈管狀，包括溝道41，其直徑比桿20的直徑稍大，使桿可插溝道41內，如第1b圖所示。選用套筒40的長度比桿20長度為短，使桿20的第一連接段20a和第二連接段20b，在組合狀態，從溝道41露出，如第1b圖所示。桿20的第一連接段20a和第二連接段20b間之第三連接段20c，容納在套筒40的溝道41內。套筒長度最好大約相當於骨骼固定裝置容納組件間之距離，或是稍大。
茲參見第2至4圖說明，桿20與骨骼固定元件1的容納組件6連接。為便利說明，第3圖中省略套筒40。套筒40置於桿20上，後者再固設於骨骼固定元件1之各容納組件6內。
在此具體例中的骨骼固定元件1為多軸骨釘，含莖部2有骨骼螺紋，在一端之尖部3，和另一端之球形頭部4。在頭部4與莖部相反側，設有凹部5，可與旋入工具結合。容納組件6有第一端7，與第一端對立之第二端8，以及與第一端和第二端的平面交叉的縱軸線9。設有與縱軸線9共軸的腔孔10，從第一端7延伸到離第二端8預定距離處。在第二端8，設有開口11，其直徑較腔孔10直徑為小。鄰近開口11設有球形或其他斜縮截面12，形成球形頭部4底座。
容納組件6又有U形凹部13，在第一端7開始，朝第二端8方向延伸，至離該第二端預定距離處。利用U形凹部13，形成二股部14,15，朝第一端7延伸。鄰近第一端7，容納組件6在該股部14,15包括陰螺紋。
詳見第3圖，設有第一施壓元件17，具有圓筒形構造，其外徑只比腔孔10內徑稍小，使第一施壓元件17可引進入容納組件之腔孔10內，並在軸向移動。施壓元件17在朝向第二端8的下側，包括球形凹部18，其半徑相當於骨釘球形頭部4之半徑。在相反側，第一施壓元件17具有圓筒形凹部19，橫越縱軸線9延伸。選用此凹部之側向直徑，使桿20要容納入容納組件內之圓形截面連接段20a或20b，可插入凹部19內，在其內側向導引。選自圓筒形凹部19的深度，使得桿20的連接段插入並壓緊U形凹部13底部時之組合狀態下，第一施壓元件17即對頭部5施壓。再者，深度以大約桿20連接段直徑之半為佳。由第3圖可見，第一施壓元件17具有共軸腔孔21，供導引旋入工具穿過。
如第3和4圖所示，骨骼固定元件又包括第二施壓元件23，具有第一端24和第二端25。第二施壓元件的寬度，使第二施壓元件可插入容納組件6之U形凹部13內。第二施壓元件的兩側包括二凸部26，套入陰螺紋16限定之空間內，在第二施壓元件插入時，可沿陰螺紋滑動。
由第2圖可見，第二施壓元件23又包括圓筒形凹部27，從第二端25朝第一端24方向延伸，其圓筒軸線垂直於圓筒形凸部26的軸線。圓筒形凸部26在第二端側包括下緣26a。圓筒形凹部27的直徑相當於桿20的連接段直徑，而其深度相當於連接段直徑之半或以下。
骨骼固定元件又包括內螺釘30，可旋入股部14,15之間。陰螺紋16及內螺釘30合作螺紋，可呈任何已知螺紋形狀。平面螺紋或負角度螺紋的優點是，防止股部14,15張開。
容納組件6及第一施壓元件17，在兩側具有相對應縮孔32,33，藉此可將螺釘1、容納組件6和第一施壓元件17可鬆弛組合。如第3和4圖所示，第一施壓元件和第二施壓元件23分別具有凸部22,28，有利於彈性桿20的固定。
屈曲性穩定裝置的其他部份，除桿和套筒以外，由常用生理相容性材料製成，諸如不銹鋼或鈦，或適於骨釘之任何其他材料。
使用上，將至少二骨骼固定裝置固定於骨骼內。其次，選用桿20和套筒40，並組合達成屈曲性穩定裝置之所需彈性性能。若例如二脊椎以上要連接，可選用具有不同彈性性能之不同套筒40，設在不同脊椎之間。如此一來，穩定裝置之彈性性能，可在手術之時適應。最好選擇套筒的長度，相當於梗釘旋入相鄰脊椎內時，二容納組件間之距離。由於桿20和套筒40是彈料性材料製成，在手術當中可縮短。然後，桿20連同套筒40，或者如果有一活動節以上要經由單桿加以穩定，則連同複數套筒，插入骨骼固定元件之容納組件6。最好在二相鄰脊椎的平衡位置，套筒要與容納組件接觸。
然後，把第二施壓元件23插入容納組件內，內螺釘旋入股部之間。調節骨釘的角度位置後，把內螺釘30旋緊。利用內螺釘30對第二施壓元件23所施壓力，把桿20夾持第一和第二施壓元件之間，同時把骨釘的頭部4鎖定於角度位置。
其次，參見第5至8b圖說明屈曲性穩定裝置之彈性性能。在第5圖中表示組合之穩定裝置，以桿20和套筒40配置成把設在形成活動節的相鄰脊椎W內之二多軸梗釘加以連接。梗釘的莖部位置，以虛點線表示。由第5圖可見，骨骼固定元件1的容納組件6，在桿20和套筒40非預力狀態之平衡位置，其距離為x。
第6a圖表示穩定裝置發生屈曲。於屈曲之際，對桿20施以拉應力，造成桿伸長。骨骼固定元件間之距離，增加至x＋△x1 。距離增加△x1 ，受到桿20因其彈性性能產生恢復力的限制。距離增加可例如在大約1.5 mm範圍。因此，屈曲/壓縮主要受到內桿20的控制。
第6b圖表示穩定裝置發生拉伸，拉伸時，由骨骼固定元件1的容納組件6對桿20和套筒40施以壓縮力。桿20和套筒40的彈性，容許容納組件6間之距離減到x－△x2 。由於桿20和套筒40的彈性性能，恢復力作用於容納組件6，限制距離減小。距離可例如減小約0.5 mm。因此，拉伸受到內桿20壓縮力的控制，被套筒所限制。
在變通應用方式中，套筒在平衡狀態受到預壓縮和/或桿在平衡狀態受到預應力。
第7圖表示桿20和套筒40進行可能之變形。第8a和8b圖表示桿20和套筒40在屈曲(第8a圖)和拉伸(第8b圖)中之變形。
第9a和9b圖表示穩定裝置之應用例。第9a圖表示二相鄰脊椎V,V'，再脊椎側彎症情況下，彼此相對中度側向傾斜。為動態穩定和校正如此活動節，可在左、右側使用有不同套筒400,400'之桿200,200'，左側桿200所用套筒400長度，較右側桿200'所用套筒400'長度為大。如此一來，可消弭二脊椎在左側的傾斜。此外，套筒400的外徑可與套筒400'不同，以便相對於左側和右側有不同的運動控制。
上述具體例可進一步修飾。在上述具體例中，套筒40有空心圓筒形狀；然而，套筒可有不同形狀。例如可為長胴形，套筒長度可與圖示具體例不同。桿20亦可呈長方形、四方形、橢圓形或三角形截面，或任何其他適當形狀之截面。在此情況下，套筒40的形狀經適當肆應。具體言之，可形成形狀在縱向變化之桿和/或套筒。桿和套筒可形成高度屈曲性或難得屈曲性。
桿和/或套筒的表面可以結構化。第10圖表示具有波紋表面的內桿201例，波紋300設在周緣方向。套筒401內壁有相對應波紋，與桿合作。此舉可防止或減少套筒相對於桿移動。
在上述骨骼固定元件中，骨骼固定元件1的莖部2是多軸向連接於各容納組件6。然而，亦可提供單軸連接。
對內螺釘30，所有已知修飾均可知，亦包含使用外環或螺帽。
在所述具體例內，骨骼固定元件是從頂部引進到容納組件內。然而，骨骼固定元件亦可從容納組件底部引進，只要構造容許。
骨骼固定元件頭部和軸可構成分開組件，加以連接。
