Abstract

一種腓骨截斷處之防止骨融合銜接裝置，係包括：第一銜接部，用以銜接位於脛骨外側且經截斷的腓骨第一截斷端；以及第二銜接部，用以銜接該腓骨之第二截斷端；以及一彈性部，銜接於該第一、二銜接部間，令該彈性部可因第一、二銜接部間之作用力，而彈性變形；如是藉由本發明銜接在腓骨截斷處的兩端，可有效防止被截斷的腓骨呈剛性再度融合，以移除患者脛骨外側之支撐力，使脛骨平台得以均勻的沉降。

Description

腓骨截斷處之防止骨融合銜接裝置
本發明係有關於一種腓骨截斷處之防止骨融合銜接裝置，尤指一種應用於銜接經截斷的腓骨兩端，且可隨外力變形，以有效防止被截斷的腓骨呈剛性再度融合，減除對脛骨外側的支撐力量，並牽制受截斷腓骨的銜接裝置。
膝關節病變，大多數是因外傷、退化或者骨質疏鬆等等原因所造成；目前對於治療膝關節病變，大都數是採用更換人工關節的方法，解除患者病灶，但由於更換人工關節手術，必須切除患者大部分的骨頭，病患必須切割較大的傷口，使得此類的手術具有較大的風險及復原較慢的缺點。
近期醫界，針對骨質疏鬆所導致的內側膝關節病變，提出「膝關節不均勻沉降」理論，該理論指出，當人體脛骨的骨質疏鬆或退化後，會產生沉降現象，但由於人體脛骨的外側，受腓骨所支撐，因此脛骨平台會發生不均勻沉降，使人體所承受的重力，會朝脛骨內側偏移，因而導致的膝關節內側病變，造成患者膝關節疼痛、不適。依該理論，對於此類病變的解決方式，是將位於脛骨外側的腓骨施予截斷手術，即移除脛骨外側的支撐，使脛骨平台可以獲得均勻的沉降，而使脛骨內側釋壓，病患因而可以獲得解緩、清除因此類病灶所產生膝關節痠痛與不適感。
然上述方法中，患者的腓骨截斷後，並無適當的銜接構件可以將截斷後的腓骨予以限制、銜接；若採用習知廣用於骨科之剛性板連接，將使被截斷的腓骨又再度呈剛性融合在一起，而失去截斷腓骨的意義；緣此，患者在截斷腓骨後的復原過程中，腓骨於患者的腿內，受肌肉牽引而擺動、位移，或者任腓骨於截斷端之骨組織隨意生長，毫不受限制；也因如此，患者並無法獲得穩定、良好的預期復原結果，徒增手術失敗的風險。
另外，在臨床上，有部分患者經過多年後，由於腓骨被截斷處較為趨近，並且沒有被有效的隔開，因沉降作用使原本分離的腓骨兩截斷端，又接觸在一起，導致腓骨於截斷處產生融合，重新對脛骨外側產生支撐力，又使脛骨發生不均勻沉降，而使患者脛骨內側痠疼病灶復發，導致治療失敗。
本案發明人有鑑於此，乃加予研究，揭示出本發明所示腓骨截斷處之防止骨融合銜接裝置。
本發明之目的旨在提供一種腓骨截斷處之防止骨融合銜接裝置，係包括：一第一銜接部，用以銜接該腓骨截斷處之第一截斷端；一第二銜接部，用以銜接該腓骨截斷處之第二截斷端；以及一彈性部，銜接於該第一、二銜接部間，令該彈性部受第一、二銜接部之作用力而彈性變形；如是便可以藉由本發明銜接於被截斷的腓骨兩端，使被截斷的腓骨不呈剛性接合或融合，藉由該彈性部可隨外力變形的特性，使受銜接的腓骨不再對脛骨的外側產生強大的支撐力，而移除患者脛骨外側之支撐，確保脛骨平台獲得均勻地沉降，以消除患者脛骨內側受壓迫產生痠痛的病灶， 並且可以解決腓骨截斷端任意擺動的問題。

如第十四圖所示，本發明所揭示腓骨截斷處之防止骨融合銜接裝置，其中該第一、二銜接部11、12與該彈性部13，係可由矽膠等彈性材料一體成型，令其第一端軸向地凹設該第一套穴111，界定為該第一銜接部11，而其第二端軸向地凹設該第二套穴121界定為該第二銜接部12，並於該第一、二銜接部11、12間，界定形成該彈性部13，且該彈性部13呈實心狀者。
如第十五圖所示，本發明所揭示腓骨截斷處之防止骨融合銜接裝置，其中該第一、二銜接部11、12與該彈性部13，係由彈性材料一體成型，於該第一、二銜接部11、12外緣，環設有多道突緣環15，以避免該第一、二銜接部11、12在套接腓骨F的過程中，發生迸裂，另外也可作為不同病患使用長度進行裁剪的依據。
如第十六圖所示，本發明所揭示腓骨截斷處之防止骨融合銜接裝置，其中該第一銜接部11與該彈性部13是一體成型，而該第二銜接部12是可滑套於該第一銜接部11與彈性部13外。或如第十七圖所示，猶可令該彈性部13是穿套於該第一、二銜接部11、12間。藉由上述各元件間可以相互滑動調整，可以使本發明適用於不同患者所需要的安裝長度。
如第十八及十九圖所示，本發明所揭示腓骨截斷處之防止骨融合銜接裝置，其中該第一、二銜接部11、12，係可製自如鈦合金等金屬材料，而該彈性部13係製自如矽膠等彈性材料，令該彈性部13兩端分別嵌接該第一、二銜接部11、12。上述該第一、二銜接部11、12，係分別設有 嵌溝或嵌孔112、122，使成型該彈性部13時，該彈性部13可以嵌入該嵌溝或嵌孔112、122中，以穩固地結合該第一、二銜接部11、12與彈性部13。
本發明所揭示腓骨截斷處之防止骨融合銜接裝置，由於可以銜接在被截斷腓骨F的兩端，呈非剛性銜接，使本發明可隨外力彈性變形，因此可有效消除脛骨T外側的支撐力、避免腓骨F被截斷端之骨組織任意生長，也可以限制被截斷腓骨任意位移，並可阻擋被截斷的腓骨再度因接觸融合再一起，以增近患者治癒機會，而顯本發明之新穎性與進步性。
本發明所揭示之結構、形狀，可於不違本發明之精神與範疇下予以修飾應用，本發明並不自限於上述實施方式。
