背景技术Background technique
四肢节段骨假体是针对四肢大段骨(括骨干、干骺)缺损修复的临床需求的一种组配式假体系统，虽然该假体系统前期干骺端骨械结合界面及侧翼固定孔可通过螺钉固定，加上四肢长段骨工况力学复杂性，经通过螺纹结构与骨结核，无法满足假体初期稳定性要求，因此需要增加固定装置对假体与宿主骨进一步固定，确保假体服役治疗过程的整体稳定性。增加的固定装置主要参考用于该部位创伤固定钛板，由于患者骨缺损的差异化及节段骨假体的特定结构形态，导致市场现有固定钛板无法与自主开发的节段骨假体准确组配使用，尤其是与假体固定孔位置的界面匹配、固定孔位等等。Limb segmental bone prosthesis is a modular prosthesis system aimed at the clinical needs of repairing large segmental bone (including diaphysis and metaphysis) defects in the limbs. The holes can be fixed by screws, and the mechanical complexity of the long segment of the limbs, through the screw structure and bone nodules, cannot meet the initial stability requirements of the prosthesis. Therefore, it is necessary to add a fixation device to further fix the prosthesis and the host bone to ensure The overall stability of the prosthesis service during treatment. The added fixation device mainly refers to the titanium plate used for trauma fixation in this part. Due to the differences in bone defects of patients and the specific structural shape of the segmental bone prosthesis, the existing fixed titanium plate in the market cannot be compared with the self-developed segmental bone prosthesis. Accurate combination and use, especially the interface matching with the position of the prosthesis fixing hole, the position of the fixing hole, etc.
传统技术中，现有桥接组合式的内固定系统，初期和远期固定均依赖机械螺钉固定，鉴于四肢长段骨服役过程力学工况复杂性，后期钉棒松动甚至折断的风险大大增加，稳定性较差，服役寿命短。In the traditional technology, the existing bridging combined internal fixation system relies on mechanical screw fixation for both initial and long-term fixation. In view of the complexity of the mechanical conditions during the service process of long-segment bones of the limbs, the risk of screw rod loosening or even breaking in the later stage is greatly increased. Poor performance and short service life.

此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of these features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.
在本发明中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。In the present invention, unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection" and "fixation" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection , or integrated; it may be mechanically connected or electrically connected; it may be directly connected or indirectly connected through an intermediary, and it may be the internal communication of two components or the interaction relationship between two components, unless otherwise specified limit. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention according to specific situations.
在本发明中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。In the present invention, unless otherwise clearly specified and limited, the first feature may be in direct contact with the first feature or the first and second feature may be in direct contact with the second feature through an intermediary. touch. Moreover, "above", "above" and "above" the first feature on the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. "Below", "beneath" and "beneath" the first feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is less horizontally than the second feature.
需要说明的是，当元件被称为“固定于”或“设置于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“上”、“下”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element.
