Description

脊突間固定裝置interspinous fixation device

本發明係關於一種脊突間固定裝置；特定而言，係關於一種具有側翼及其通孔之脊突間固定裝置。The present invention relates to a fixation device between ridges; in particular, it relates to a fixation device between ridges with flanks and through holes thereof.

脊椎不適的治療可包括長期醫藥治療或手術。醫藥治療通常是控制症狀，譬如疼痛，而非排除問題。就某些病人而言，此需要長期服藥，因而改變病人的心理狀況，或產生副作用。另一種選擇為手術，但其具侵犯性，且可能會改變脊椎的解剖上的結構及功能。譬如，脊椎融合固定手術，使得兩節或數節椎骨可使用自體骨以及/或人工植入物而融合。融合固定方法是非可逆轉的，且可顯著地改變脊椎骨的活行動範圍。Treatment of spinal discomfort may include long-term medical treatment or surgery. Medical treatment is usually to manage symptoms, such as pain, rather than to eliminate the problem. For some patients, this requires long-term medication, thereby changing the patient's psychological state, or causing side effects. Another option is surgery, but it is invasive and may alter the anatomical structure and function of the spine. For example, spinal fusion and fixation procedures allow two or more vertebrae to be fused using autologous bone and/or artificial implants. Fusion fixation methods are non-reversible and can significantly alter the range of motion of the vertebrae.

美國專利第8118839號揭示一軟質脊突間填充塊，為可以壓縮且具彈性的脊突間填充塊，可避免硬質脊突間填充塊使用時因應力集中於脊突結構所造成的脊突斷裂。軟質脊突間填充塊皆具備雙翼結構，即在脊突間填充塊的左右兩側各有兩個大小相同的翼狀突起，該對稱雙翼結構可以提供脊突間填充塊在2個脊突之間較佳的貼合效果。然而此填充塊由兩條綁線從填充塊外繞脊突固定，較無固定填充塊效果。US Patent No. 8,118,839 discloses a soft interspinous filling block, which is a compressible and elastic interspinous filling block, which can avoid the ridge fracture caused by the stress concentration on the ridge structure when the rigid interspinous filling block is used. . The soft inter-spine filling blocks all have a double-wing structure, that is, there are two wing-like protrusions of the same size on the left and right sides of the inter-spine filling block. Better fit between protrusions. However, this filling block is fixed by two binding wires from the outside of the filling block around the ridge, which has no effect of fixing the filling block.

有鑑於此，因此本技術領域亟需一種脊突間固定器解決前述問題。In view of this, there is an urgent need in the technical field for an interspinous fixator to solve the aforementioned problems.

為解決上述之問題並達成發明之目的，本揭露係關於一種脊突間固定裝置，可同步應用於脊突後方與側邊置入之優點，亦具備良好的繩線綁定機制，以提高填充塊固定性，降低填充塊脫出的機率，同時和脊突更緊密貼合，具有固定脊椎的效果。In order to solve the above problems and achieve the purpose of the invention, the present disclosure relates to an inter-spinous fixation device, which can be simultaneously applied to the advantages of the posterior and lateral implantation of the spine, and also has a good wire binding mechanism to improve filling.
