Description
本發明係有關一種骨科用旋轉骨釘，尤指一種可單軸旋轉、固定之骨科用旋轉骨釘。The invention relates to a rotating bone nail for orthopedics, in particular to a rotating bone nail for orthopedics which can be uniaxially rotated and fixed.
一般而言，脊椎並不是成一直線，而脊椎固定裝置中的固定桿卻成一直線，目前的解決方式不外乎以下數種結構：In general, the spine is not in line, and the fixed rods in the spinal fixation device are in a straight line. The current solution is nothing more than the following structures:
1.使用具有角度的骨釘，以抵消待固定骨節間的角度，例如參見TW-183341、TW-168911等。但該等結構，必須進行精確的術前評估，也不容許手術中任何偏差，以免無法完全或過度抵消待固定骨節間的角度。1. Use angled bone nails to counteract the angle between the joints to be fixed, see for example TW-183341, TW-168911, etc. However, such structures must be accurately pre-operatively evaluated and do not allow for any deviations in the procedure so as not to completely or excessively offset the angle between the segments to be fixed.
2.使用外加的固定結合塊，以抵消待固定骨節間的角度，例如參見TW-250680、TW-292540等。但該等結構必須外加固定結合塊、額外的結合螺帽等元/組件，佔用較大的手術空間，以致延長手術時間和術後癒合時間。2. Use an additional fixed binding block to offset the angle between the bone segments to be fixed, see for example TW-250680, TW-292540, etc. However, such structures must be supplemented with a fixed binding block, an additional combined nut or the like, occupying a large surgical space, thereby prolonging the operation time and the postoperative healing time.
3.以萬向結合裝置(universal connecting device)解決問題，諸如US-5,474,551、US-5,507,746、US-5,575,791等；例如US-5,474,551係利用萬向墊片固定裝置(a universal pad fixation device)，來解決上述脊椎骨節通常並不平行問題。但該等結構相對較為複雜，對醫生來說操作較麻煩以致延長手術時間，且由於該等結構是側邊鎖定且可供活動的關節較多，對整體裝置的穩定度及可承載的荷重皆較U型固定桿差。3. Solving problems with a universal connecting device, such as US-5,474,551, US-5,507,746, US-5,575,791, etc.; for example, US-5,474,551 utilizes a universal pad fixation device. Solving the above-mentioned vertebrae is usually not a parallel problem. However, these structures are relatively complicated, which is cumbersome for the doctor to prolong the operation time, and since the structures are laterally locked and there are many joints available for movement, the stability of the whole device and the load that can be carried are both It is worse than the U-shaped fixed rod.
4.使用雙調整墊片固定結構，以抵消待固定骨節間的角度，例如參見TW-294034。但該等結構只適用於骨板-骨釘固定系統，不能用於U型桿-固定桿系統。4. Use a double shims to secure the structure to counteract the angle between the joints to be fixed, see for example TW-294034. However, these structures are only applicable to the bone plate-bone nail fixation system and cannot be used for the U-bar-fixed rod system.
5.以多軸螺釘(polyaxial screw)解決問題，諸如美國核准專利US-5520690、US-5531746、......US-71862552、US-7207992等三十九筆，及美國相關的公開專利申請案US-20010012937、US-20020111626、......、US-20070161995、US-20070162006等。這是目前的主流技術。該等技術基本上都是利用多軸骨釘來解決上述脊椎骨節通常並不平行問題。該等多軸骨釘雖可輕易解決脊椎骨節通常並不平行的問題，但該多軸骨釘之U型承座部與該多軸螺釘間的穩定度卻並不甚佳，因此，如何既能輕易解決脊椎骨節通常並不平行的問題，又能使骨釘之螺釘與骨釘之U型承座部間的結合更加穩定，實為一大考驗。5. Solve problems with polyaxial screws, such as US approved patents US-5520690, US-5531746, ... US-71862552, US-7207992, etc., and US related public patents Application US-20010012937, US-20020111626, ..., US-20070161995, US-20070162006, and the like. This is the current mainstream technology. These techniques basically utilize polyaxial bone nails to solve the problem that the above-mentioned vertebrae are usually not parallel. Although the multi-axial bone nails can easily solve the problem that the spine joints are usually not parallel, the stability between the U-shaped socket portion of the multi-axis bone nail and the multi-axis screw is not very good, therefore, how It can easily solve the problem that the vertebrae are usually not parallel, and it can make the combination of the screw of the nail and the U-shaped seat of the nail more stable, which is a big test.
本發明之骨科用旋轉骨釘，其利用單軸旋轉機制使骨釘之承座部與螺釘間結合的穩定度大幅提升，進而可承受更大的重量，此外，該單軸旋轉機制也可調整骨釘之角度，且進一步搭配球弧襯墊的使用(請參見發明人等同日申請的另一項專利申請案「骨科用萬向襯墊固定結構」)，更能輕易調整固定桿及骨釘的角度，以解決脊椎骨節通常不平行的問題。本發明之骨科用旋轉骨釘亦可進一步搭配本發明之發明人等同日申請的另兩項專利「脊椎固定系統」、「脊椎固定系統」的使用，不僅大幅提升骨釘的穩定性、可輕易調整角度、更提供彈性功能，以解決現有脊椎固定系統常有之骨釘退出(pull out)及因無彈性功能而使得壓力更集中於上下兩節骨節，加速上下兩骨節出問題的缺點。The rotating bone nail for orthopedics of the present invention utilizes a uniaxial rotation mechanism to greatly improve the stability of the joint between the socket portion and the screw of the nail, thereby further bearing a greater weight, and the single-axis rotation mechanism can also be adjusted. The angle of the nail, and further with the use of the ball arc pad (please refer to another patent application "orthopaedic universal pad fixing structure" applied by the inventor equivalent day), it is easier to adjust the fixed rod and nail The angle to solve the problem that the vertebrae are usually not parallel. The orthopedic rotary nail of the present invention can be further matched with the use of the other two patents "spine fixation system" and "spine fixation system" applied by the inventor of the present invention on the equivalent date, which not only greatly improves the stability of the nail, but also can be easily Adjusting the angle and providing the elastic function to solve the problem that the existing spine fixation system often has the nail pull out and the inelastic function makes the pressure more concentrated on the upper and lower joints, accelerating the upper and lower bone joint problems.
