背景技术Background technique
胫骨为小腿骨中的主要承重骨，胫骨上端与股骨下端形成膝关节。胫骨与股骨下端接触的面为胫骨平台。胫骨平台骨折在临床中是常见的关节内骨折，多见遭受高能量损伤的中、青年人。由于骨折形态复杂多变，胫骨平台骨折一直是创伤骨科治疗的难点，特别是复杂胫骨平台骨折的治疗，有较高的并发症及致残率。临床治疗较为棘手。胫骨平台骨折治疗目的是恢复关节面平整及下肢力线、坚强固定骨折块、避免出现术后创伤性关节炎、关节僵硬等远期并发症。在胫骨骨折患者中，胫骨近端杆骨骨折伴随胫骨近段关节面塌陷型骨折时有发生。The tibia is the main load-bearing bone in the lower leg bone, and the upper end of the tibia and the lower end of the femur form the knee joint. The surface of the tibia in contact with the lower end of the femur is the tibial plateau. Tibial plateau fractures are common intra-articular fractures in clinical practice, and are more common in young and middle-aged people who have suffered high-energy injuries. Due to the complex and changeable fracture morphology, tibial plateau fractures have always been a difficult point in the treatment of trauma orthopedics, especially the treatment of complex tibial plateau fractures, which have a high complication and disability rate. Clinical treatment is more difficult. The purpose of the treatment of tibial plateau fractures is to restore the smoothness of the articular surface and the alignment of the lower limbs, firmly fix the fracture fragments, and avoid long-term complications such as postoperative traumatic arthritis and joint stiffness. In patients with tibial fractures, proximal tibial rod fractures occur frequently with collapsed fractures of the proximal articular surface of the tibia.
扎起相关技术中，此类病例目前常采用的治疗方法是，采用前外侧间接复位后，辅以外侧接骨板和接骨螺钉连接固定。接骨螺钉通过接骨板单独穿过关节面平台塌陷性骨折的骨块碎片固定到整体骨上，治疗方案易操作，但存在固定不牢的缺陷，且对于术后康复屈膝锻炼时会造成一定的复位丢失。导致关节位置不稳定。Among the related techniques of ligation, the current treatment method for such cases is to use anterolateral indirect reduction, supplemented by lateral bone plate and bone screw connection and fixation. The bone screw is fixed to the whole bone through the bone plate alone through the bone fragment of the articular surface platform collapsing fracture. The treatment plan is easy to operate, but it has the defect of unstable fixation, and it will cause a certain reduction in the postoperative rehabilitation of knee flexion exercise. lost. lead to instability of the joint position.

本实施例的接骨板组件在手术操作过程中，行外侧手术切开，保护重要血管神经，显露骨折部位，进行关节复位，清理手术部位，确定手术中所需胫骨平台外侧接骨板及螺钉的规格和数量，实施植入手术，植入填充固定件30、第一弧形板体10以及第二弧形板体20固定到手术要求位置，实现手术目的。During the operation of the bone plate assembly of this embodiment, a lateral surgical incision is performed to protect important blood vessels and nerves, expose the fracture site, perform joint reduction, clean the operation site, and determine the specifications of the lateral bone plate and screws of the tibial plateau required during the operation. and quantity, the implantation operation is performed, and the implant filling and fixing
本实施例的第一弧形板体10和第二弧形板体20采用医用金属制成，所述医用金属包括但不局限于钛及钛合金、钴合金、不锈钢以及钽金属、镁合金，此类金属材料在ISO-5830系列国际标准中均有规定，其生物相容性已经得到国内外多年骨科植入应用的实践证实。The first arc-shaped
在本实用新型的描述中，需要理解的是，方位词如“前、后、上、下、左、右”、“横向、竖向、垂直、水平”和“顶、底”等所指示的方位或位置关系通常是基于附图所示的方位或位置关系，仅是为了便于描述本实用新型和简化描述，在未作相反说明的情况下，这些方位词并不指示和暗示所指的装置或元件必须具有特定的方位或者以特定的方位构造和操作，因此不能理解为对本实用新型保护范围的限制；方位词“内、外”是指相对于各部件本身的轮廓的内外。In the description of the present invention, it should be understood that orientation words such as "front, rear, top, bottom, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" etc. The orientation or positional relationship is usually based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and these orientations do not indicate and imply the indicated device unless otherwise stated. Or elements must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be construed as a limitation on the protection scope of the present invention; the orientation words "inside and outside" refer to the inside and outside relative to the contour of each component itself.
为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位)，并且对这里所使用的空间相对描述作出相应解释。For ease of description, spatially relative terms, such as "on", "over", "on the surface", "above", etc., may be used herein to describe what is shown in the figures. The spatial positional relationship of one device or feature shown to other devices or features. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or features would then be oriented "below" or "over" the other devices or features under other devices or constructions". Thus, the exemplary term "above" can encompass both an orientation of "above" and "below." The device may also be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptions used herein interpreted accordingly.
此外，需要说明的是，使用“第一”、“第二”等词语来限定零部件，仅仅是为了便于对相应零部件进行区别，如没有另行声明，上述词语并没有特殊含义，因此不能理解为对本实用新型保护范围的限制。In addition, it should be noted that the use of words such as "first" and "second" to define components is only for the convenience of distinguishing corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood To limit the scope of protection of the present invention.
以上所述仅为本实用新型的优选实施例而已，并不用于限制本实用新型，对于本领域的技术人员来说，本实用新型可以有各种更改和变化。凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
