Description

骨骼固定總成
本發明係關於一種骨骼固定總成，可用於脊柱手術或創傷手術。具體而言，本發明係關於一種骨骼固定總成，包括至少二骨骼固定元件，有容納元件供容納桿，該桿係連接骨骼固定元件之用，其中桿是利用形式鎖定連接方式，固定於容納組件內。
US 5,207,678號揭示一種梗釘，包括螺釘，以及容納構件，把螺釘與桿連接。桿是螺紋桿，利用結合容納構件外側，且可在螺紋桿上調節之二螺帽，鎖定在容納構件內。為再調節桿相對於容納構件之位置，螺帽可在螺紋桿上轉動。此項程序費時，因為始終有二螺釘需要調節。 US 5,443,467號揭示一種骨骼固定總成，包括骨骼固定元件，有容納組件供容納桿，又有內螺釘和外鎖定螺帽，可將桿保固和固定於容納組件內。桿具有滑順表面。桿的固定是利用摩擦式鎖定達成。即使桿需要暫時鎖定，容許在稍後步驟中再調節，仍必須應用相當的力矩，才能達成充分的夾持力。
US 5,716,356號揭示一種固定構件，要與螺紋桿連接。固定構件有軸要固定於骨骼內，並有U形斷面的容納組件，以容納桿。利用凹部形成二開口股部，設有陽螺紋和陰螺紋。設有螺帽構件，要螺合於陽螺紋，而鎖定構件要螺合於股部之間。不論螺帽構件或鎖定構件或二者，具有凸部，與螺紋桿結合。固定構件又包括在U形凹部底之預載彈簧構件，作用於桿，以便一方面得固定構件和桿間之堅固連接，另方面可容易操作，準確調節固定構件和桿間之位置，最後鎖定位置。由於有彈簧構件存在，如果鎖定構件尚未完全鎖緊，桿仍可在縱向移動。又因彈簧構件的存在，桿和容納組件間之連接始終是摩擦式鎖定之功，需要應用大力矩，以供充分夾持。
US 5,961,517號揭示一種調節工具，以調節桿在如此固定構件內之位置。
本發明之目的，在於提供一種骨骼固定總成，可快速準確調節和再調節桿相對於固定構件之位置，不需用到大扭矩力道。
此目的係由申請專利範圍第1項之骨骼固定總成達成。進一步發展則列於申請專利範圍附屬項。
骨骼固定總成的優點是，較之桿經由摩擦式鎖定方式固定，經鎖定元件應用微小力矩，就可對桿提供大夾持力。此舉可在調節和再調節桿位置的過程中，對鎖定元件應用小力矩，即可方便桿的暫時固定。由於形式鎖定連接，暫時固定有充分強度，在對桿進行操作時防止鬆弛。再者，只要把內螺釘稍微回轉，就可將暫時固定很快鬆弛。所以，骨骼固定裝置適於應用在脊柱變形之矯正，諸如脊柱側彎症，在手術當中需要多次再調節桿的位置，直至最後鎖定為止。
若骨骼固定總成包括棘輪式桿，具有另一優點，即棘輪式桿需要較低的固定力矩，即可達成螺紋桿或光滑桿同樣的保持力。
由於應用比先前技術的裝置為低的力矩，達成桿之預固定，可減少容納組件的股部張開。
本發明其他特點和優點，由如下參照附圖詳述，即可最為明白。
第1至7圖所示固定裝置之第一具體例，包括骨骼固定元件1，有螺紋軸2和容納組件3。容納組件3實質上呈圓筒形，並具有U形凹部4，在螺紋軸側有底部5。利用U形凹部4，形成二自由股部6,7。在U形凹部4形成的溝道內，設備具有陰螺紋8之腔孔，形成與螺紋軸2的中心軸線共軸。陰螺紋8具有任何已知的螺紋形狀。然而，以平面螺紋或負角度螺紋為宜，因可防止股部6,7張開。
固定總成又包括縱向桿9，具有結構化表面。在圖示具體例中，桿具有圓形斷面。結構係棘輪式結構，包含複數沿周凹溝10，利用沿周峰部11分開。
為使桿9固定於容納組件內，設有鎖定構件12。在此具體例中的鎖定構件為內螺釘或固定螺釘，要螺合於股部6,7間之陰螺紋8。內螺釘12包括環形凸部13，在朝向桿之側面，如第2至5圖所示。環形凸部13維度的選擇，是以桿的凹溝10維度為函數，使環形凸部13在螺合於桿上的位置，與凹溝10結合，如第3和4圖所示。凹溝10和相對應凸部13的形狀以圓形為佳。
如第3、4、6、7圖所示，容納組件3在U形凹部4的底部5具有結構，可與桿表面的結構結合。在圖示具體例中，結構包括複數凸部14，利用刻線15分開，按橫越凹部4所界定之溝道縱軸線L的方向沿周延伸。選擇凸部14的維度，容許與桿之凹溝10結合。凸部數視凹溝以及凹部的底部可用空間而定。
特別如第6和7圖所示，容納組件又有中心凹部16，在U形凹部4形成的溝道底部。利用凹部16，把凸部14分成二組，分別位於凹部16的右側和左側。此項配置較使用彎桿在溝道底部5全面設凸部的情形為佳。
第6和7圖所示結構的凸部14間之刻線15，又細又銳。在修飾例中，刻線15寬度可在凸部14間形成凹谷。凹谷可打圓或其他造型。同理，棘輪型桿的結構可有尖銳峰部11，或是圓滑或其他造型之峰部11。棘輪型桿和內螺釘的相對應環狀凸部13，以及容納組件底部等之結構，是按照所用材料和/或結構在結合時所需作用力，加以選擇。
同理，容納組件3底部5上之凸部數，是按照特別需要選擇。如第8和9圖所示，可在凹部16各側設有唯一單凸部14'。又，內螺釘12可有單一凸部以上，與桿結合。
製造骨骼固定總成組件之材料，是生理相容性材料，例如鈦、不銹鋼，或是骨釘可用之其他材料。材料可因不同元件而異。尤其是材料要夠硬，才能在桿和骨骼固定元件之間有實體形式鎖定連接。
操作時，首先把至少二骨骼固定元件螺入骨骼內，尤其是相鄰脊椎骨。然後，把桿9置入骨骼固定元件的容納組件之U形凹部4內，使其表面結構10,11與容納組件底部的結構14,15結合。然後，把內螺釘12旋入。一旦環形凸部13與桿表面的結構結合，桿即以形式鎖定方式，亦即積極連接，保持在容納組件內，防止桿在任一方向運動。由於形式鎖定或積極鎖定連接，應用低力矩即足以獲得充分預固定。
在以下階段進行微調，由此調節各固定元件在桿相對於桿縱軸線之結合位置。為了微調，稍微退轉內螺釘，以旋鬆桿結構與內螺釘結構之形式鎖定結合。由於以低力矩獲得預固定，可快速退轉固定螺釘旋鬆。此舉有利於處置和加速程序。找到固定元件相對於桿的最後位置後，旋緊內螺釘，將桿牢牢固定於容納組件內。
以上述固定總成，可以較僅靠摩擦式鎖定的光滑桿情況之預固定為低之扭矩，獲得桿之預固定。較之使用彈簧構件加以固定的結構化桿，亦是如此。再者，固定總成構造較具有彈簧元件夾持桿之構造更簡單。此有利於生產。
第一具體例之修飾如第10a、10b、11和12圖所示。與第一具體例不同的是，桿為螺紋桿9'。因此，凹溝10'和峰部11'有螺紋間距之螺旋結構。相對應地，容納組件底部的結構14"具有螺紋間距。螺紋桿9'較棘輪型桿更容易製造。
參考第13至15圖說明第二具體例。第二具體例和第一具體例不同，其中骨骼固定元件形成所謂多軸螺釘，因而容納桿之容納組件樞動連接於相關螺紋軸。此具體例與上述具體例相當之組件，使用同樣參考號碼。
骨骼固定元件101包括螺紋軸102和頭部102a，後者有球形截面形部，其凹部102b可供旋入工具結合。容納組件103實質上呈圓筒形，包括共軸腔孔，有一段103a可容納頭部102a，故頭部可以樞動方式保持於容納組件內。容納組件103又有U形凹部104，可供容納桿。利用U形凹部104，形成二股部106,107，包括陰螺紋108。
設有施壓構件120，實質上呈圓筒形，其外徑得在容納組件內前後移動。施壓構件在朝向頭部之側面，有(最好是球形)凹部121，與頭部102a之至少一部份結合。在對面側，施壓構件具有圓筒形凹部122，圓筒軸線橫越螺釘軸線延伸。圓筒形凹部之半徑，適於容納桿9。
圓筒形凹部122的表面包括凸部114，以刻線115分開，按沿周方向橫越桿軸線延伸，與桿9之凹溝10結合，與第一具體例的容納組件3之底部5結構相似。施壓元件120又有共軸腔孔123，容許旋入工具進出。施壓元件的尺寸使得在組合狀態下，其圓筒形凹部122之底部，突出容納組件的U形凹部之底部105上方，如第14和15圖所示。螺釘、容納組件和施壓元件可以預組合。
桿9和內螺釘12，與第一具體例一致。
操作時，把至少二骨骼固定元件置入二骨碎片或二相鄰脊椎骨。然後，將桿插入容納組件的U形凹部內。由於容納組件可相對於螺釘樞動，容納組件相對於螺紋軸的角度位置即可調節。在內螺釘旋入時，對桿施壓，桿對施壓元件施壓，而壓住容納組件之段103a。內螺釘以低力矩旋緊時，即可達成暫時固定或預固定。桿之暫時固定，是一方面利用內螺釘和桿，另方面藉桿和施壓元件間之形式鎖定連接所造成。微調是以第一具體例之同樣方式進行。
本發明可構想其他修飾。桿表面的結構可以變化，例如可具有波浪螺旋式渦形。例如，亦可有尖銳峰部形成鈍角。若具有如此尖銳峰部，可達成更微細層級，因為形成之齒在桿的縱向較小。然而，以圓滑形狀，可以更可靠進行微調。容納組件底部和鎖定元件所設凸部之結構，亦可變化。
可以只在一部份具有此結構，可分別選在鎖定構件、容納組件或施壓元件。
在進一步修改中，U形凹部不向容納組件頂部，而是向側面開口。
在第二具體例進一步修飾中，頭部和桿可單獨固定。在此情況下，施壓元件的圓筒形凹部可改為U形凹部，藉此形成股部，在桿上方延伸。鎖定構件包括第一螺釘，只壓住施壓元件，並有螺紋共軸腔孔，內設固定螺釘，與桿結合。
本發明不限於螺釘做為骨骼固定元件，但可以骨鉤或任何其他骨骼固定元件實施。
