Description
本發明係有關一種連桿構造，尤指一種用於鎖結連接於釘固在脊椎骨的複數骨釘之間，且其桿體具彈性變形效能的連桿構造者。 The present invention relates to a link structure, and more particularly to a link builder for locking and connecting between a plurality of bone nails fixed to a vertebra and having a rod body having elastic deformation performance.
如所知者，脊椎一旦發生移位或產生壓迫或甚至周圍肌肉、韌帶組織緊張，都會直接影響脊椎中的神經，間接引起神經供應的末端器官，肌肉或分泌腺體，造成行動不便或疼痛、身體不適，通常治療這種症狀可利用手術方法在椎脊骨間安裝固定裝置，以達減壓的效果，而習知這種治療手術略係將先骨釘分別植入固定在上、下兩節椎脊骨的適合位置，然後再於二骨釘間鎖結固設一連結桿，使骨釘間連結成一剛性固定桿結構，據此保持兩節椎脊骨間的定位，並提供一適度的支撐力，達減壓的效能。惟因人體的各節脊椎骨的生成組合角度均不相同，所以前述手術所安裝的剛性固定桿結構，對於呈曲率之人體脊椎而言，完全沒有任何角度的彈性空間，這結果不僅使病患手術後之活動能力受到極大的限制，且產生的嚴重的不適感，尤其對患有骨質疏鬆症的病人而言，這種剛性固定桿結構經常會使植設骨釘產生固結穩固性不良的問題，發生骨釘鬆動或脫落，甚且將因而傷害到脊椎骨和其周邊細胞組織；又，該剛性固定桿結構將使原有之關節失去作用，導致上下關節須承擔原有關節之功能，且其無法提供如椎間盤之柔韌、緩衝功能，因而容易使得上下節脊椎關節因過度使用而提早老化或損傷，實有改良之必要。 As is known, once the spine is displaced or compressed, or even the surrounding muscles and ligament tissue are tight, it will directly affect the nerves in the spine, indirectly causing the terminal organs of the nerve supply, muscles or secretory glands, causing inconvenience or pain. Physical discomfort, usually to treat this symptom, surgical methods can be used to install a fixation device between the vertebrae to achieve the effect of decompression, and it is known that this treatment is to fix the anterior nail separately to the upper and lower sides. The appropriate position of the vertebral spine, and then a connecting rod is fixed between the two nails to connect the nails into a rigid fixed rod structure, thereby maintaining the positioning between the two vertebrae and providing a moderate degree. Supporting force, the effectiveness of decompression. However, because the combination angles of the various vertebrae of the human body are different, the rigid rod structure installed in the above surgery has no elastic space at any angle for the human spine with curvature, which results in not only surgery for the patient. The post-activity is greatly limited, and the resulting serious discomfort, especially for patients with osteoporosis, this rigid rod structure often causes problems with poor consolidation stability of implanted nails. If the nail is loose or detached, it will even damage the vertebrae and its surrounding cell tissue; in addition, the rigid rod structure will disable the original joint, causing the upper and lower joints to bear the function of the original joint, and It is impossible to provide flexibility and cushioning function such as intervertebral disc, so it is easy to make the upper and lower joints of the spine joints age or damage due to excessive use, which is necessary for improvement.
本發明的主要目的在於改善前述問題，乃提供一種連桿構造，藉由連桿具備適當有彈性變形的效能，以因應安裝在各種不同組合角度的脊椎骨部位，可簡化手術操作難度，並使病患手術後之不適感獲得改善，提供治療部位的相鄰二脊椎骨間的自然活動能力與運動範圍，以有效地降低臨節脊椎骨的退化。 The main object of the present invention is to improve the foregoing problems, and to provide a link structure, which is characterized in that the link has appropriate elastic deformation to simplify the operation of the operation and to make the disease difficult to be installed in various vertebrae parts at different combinations of angles. The discomfort after surgery is improved, and the natural activity ability and range of motion between adjacent vertebrae at the treatment site are provided to effectively reduce the degradation of the vertebrae.
本發明的次一目的係提供一種連桿構造，該連桿可因應使用需求而提供在不同方向具有不同的彈性變形效能以符合所需，因此使連桿具備符合脊椎運作工學的撓性變形效能，可協助重建脊椎原有自然的活動能力與運動範圍，確保病患椎體活動時的舒適性。 A second object of the present invention is to provide a link structure that can provide different elastic deformation efficiencies in different directions to meet the needs according to the needs of use, thereby providing the link with flexible deformation conforming to the spine operation engineering. Efficacy can help rebuild the natural mobility and range of motion of the spine to ensure the comfort of the patient's vertebral body.
為達成上述目的，本發明之連桿構造，其主要是在連桿上設有一或一個以上的彈性部，並於該彈性部上設有一或複數的鏤空槽，利用該彈性部的鏤空槽設置，使連桿在受力時該鏤空槽的縫隙空間可產生相應的伸縮，以促進連桿之彈性變形能力，使該連桿具備可彎曲、扭轉、壓縮、拉伸、吸收與緩衝震盪的功能。 In order to achieve the above object, the link structure of the present invention is mainly provided with one or more elastic portions on the connecting rod, and one or a plurality of hollow grooves are provided on the elastic portion, and the hollow groove of the elastic portion is used. When the connecting rod is under stress, the gap space of the hollow groove can be correspondingly expanded and contracted to promote the elastic deformation ability of the connecting rod, so that the connecting rod has the functions of bending, twisting, compressing, stretching, absorbing and buffering and oscillating. .

It is better to pass over the central axis of the connecting rod; with the hollow groove 3 provided on the elastic portion 2, the gap space of the hollow groove 3 can be correspondingly stretched when the connecting rod 1 is stressed (refer to FIG. 4) To Figure 6), to promote the elastic deformation ability of the connecting rod, so that the connecting rod can be bent, twisted, compressed, pulled The function of stretching, absorbing and buffering shocks.
如圖7所示，該連桿1安裝時係被鎖結連接於二支分別釘固在二相鄰脊椎骨4之上的骨釘5，利用迫緊螺絲51而分別將該連桿1二端螺固在骨釘上端的固定座52內；於安裝後，該連桿1藉由彈性部2的設置所以可因應該等骨釘 5的植設位置以及所承受的外力而做出彎曲、扭轉、壓縮或拉伸等彈性變形態樣，以便調整成一合適的擺置角度，據此將二骨釘間(亦即兩節椎脊骨間)的相對位置保持固定，並提供一適度的支撐力，達減壓的治療效果；又當人體脊椎活動時，該連桿1的彈性變形效能可提供符合脊椎運作工學的輔助支撐力，以協助重建脊椎原有自然的活動能力與運動範圍，確保病患椎體活動時的舒適性，以及降低臨節脊椎骨的退化風險。 As shown in FIG. 7 , when the connecting rod 1 is installed, the connecting rod 1 is locked and connected to two bone nails 5 respectively fixed on the two adjacent vertebrae 4, and the connecting rod 1 is respectively terminated by the tightening screw 51. The screw is fixed in the fixing seat 52 at the upper end of the nail; after the installation, the connecting rod 1 is arranged by the elastic portion 2, so that the nail can be waited for 5, the position of the planting and the external force to make elastic deformation such as bending, torsion, compression or stretching, so as to adjust to a suitable angle of placement, according to which the two bones (ie, two vertebral ridges) The relative position of the bone remains fixed and provides a moderate support force to achieve the therapeutic effect of decompression; and when the human spine is active, the elastic deformation performance of the connecting rod 1 can provide auxiliary support force corresponding to the spine operation engineering. To help rebuild the natural ability and range of motion of the spine, to ensure the comfort of the patient's vertebral body, and to reduce the risk of degeneration of the vertebrae.
本發明並非侷限於以上所述形式，很明顯參考上述說明，能有更多的改良與變化，這例如是：因應不同的應用需求，除了如前述實施例之於該彈性部2的上、下二側設置鏤空槽3的方式之外，亦可將該等鏤空槽開設在連桿彈性部2的左右二側之上，因此可提供該連桿在左右二側之彈性變形能力(請參閱圖8至圖9)，亦可理解的，該彈性部的鏤空槽設置方式乃可因應欲彎曲變形的性能而作出最佳化參數設置；此外，請參閱圖10，當本發明之連桿1使用於多節脊椎骨固定手術時，可採用具有複數彈性部2的連桿上，因此安裝後在各骨釘5間(亦即各節椎脊骨間)均具有彈性部2，所以各段連桿均具有彈性變形效能，而分別提供各骨釘間(亦即各節椎脊骨間)連結固定和輔助支撐力；是以，凡有在相同之創作精神下所作有關本發明之任何修飾或變更，皆仍應包括在本發明意圖保護之範疇。 The present invention is not limited to the above-described embodiments, and it is obvious that with reference to the above description, there can be more improvements and variations, for example, in response to different application requirements, except for the upper and lower portions of the elastic portion 2 as in the foregoing embodiment. In addition to the manner in which the hollow grooves 3 are provided on the two sides, the hollow grooves may be opened on the left and right sides of the elastic portion 2 of the connecting rod, thereby providing the elastic deformation capability of the connecting rod on the left and right sides (see the figure). 8 to FIG. 9), it can also be understood that the hollow groove of the elastic portion is arranged in an optimized parameter setting according to the performance of the bending deformation; further, referring to FIG. 10, when the connecting rod 1 of the present invention is used In the multi-segmental spinal fixation operation, the connecting rod having the plurality of elastic portions 2 can be used, so that after the installation, the elastic portions 2 are provided between the respective nails 5 (that is, between the vertebral bones of each node), so the connecting rods of each segment All have elastic deformation performance, and provide joint fixation and auxiliary support force between each nail (that is, between each vertebra); therefore, any modification or change related to the present invention in the same creative spirit , should still be included in the intention of the present invention Protection category.
