背景技术Background technique
当人体四肢长管状骨出现骨折时，常需要对骨折进行复位、固定，相应的固定技术及材料也在不断进步与更新，如钢板、髓内钉、外固定支架等，目前常用的内固定器械是钢板，其手术固定范围大、软组织剥离多、创伤大，复位不良等弊端；术后存在由于应力遮挡而出现骨质疏松、固定物松动、甚至内固定物断棒等弊端，内固定失败后不得不进行二次手术甚至多次手术，严重影响疗效。When fractures occur in the long tubular bones of human extremities, it is often necessary to reset and fix the fractures. The corresponding fixation techniques and materials are also constantly improving and updating, such as steel plates, intramedullary nails, external fixation brackets, etc. Currently, commonly used internal fixation devices It is a steel plate, which has disadvantages such as large surgical fixation range, multiple soft tissue stripping, large trauma, and poor reduction; after surgery, there are disadvantages such as osteoporosis, loose fixation, and even broken rods of internal fixation due to stress shielding. Had to perform a second operation or even multiple operations, seriously affecting the curative effect.
骨折愈合过程复杂，国内外学者对骨折愈合理论的认识在不断完善，早期所倡导的骨折坚强固定的观点经过几十年的临床实践及实验研究证实，由于固定物的应力遮挡效应，固定骨骼易出现骨质疏松，固定物折断等问题，提出的生物的合理的接骨术观点逐渐被接受，骨折愈合受到患者年龄，力学环境，局部血运，内分泌等诸多因素影响，应力是主要因素之一，现有的各种固定器械虽然形状、结构各异，但无法进行微动调节，应用时易产生应力遮挡、出现骨质疏松，有的虽能微动，但不能精确限制微动的范围、方向、及应力的大小。The process of fracture healing is complicated, and scholars at home and abroad are constantly improving their understanding of the theory of fracture healing. The idea of strong fixation of fractures advocated in the early days has been confirmed by decades of clinical practice and experimental research. Osteoporosis, fixation fractures and other problems occur, and the biologically reasonable osteosynthesis viewpoint is gradually accepted. Fracture healing is affected by many factors such as patient age, mechanical environment, local blood supply, endocrine, etc. Stress is one of the main factors. Although the existing various fixation devices have different shapes and structures, they cannot be adjusted by micro-movement. When applied, they are prone to stress shielding and osteoporosis. Although some can be micro-moved, they cannot precisely limit the range and direction of micro-motion , and the size of the stress.
应力与骨折愈合方面：骨组织是一种粘弹性固体材料，力学特性复杂，其结构及功能与其力学特征及力学环境状态密切相关，决定了不同的应力刺激对骨代谢和骨愈合有不同影响力。在应力作用机制方面：应力影响骨折愈合过程中的细胞信号转导通路，可以通过位于细胞膜表达或跨膜存在的钙离子通道、整合素、生长因子等，将细胞外基质信号传递入细胞内。成骨细胞的机械信号偶联、细胞增殖与细胞内和细胞间Ca2+水平的升降有关，整合素是联系细胞内外信号的主要物质，外界张应力刺激下可以诱导成骨细胞内生理、生化改变，做出应答和传导信号、激活基因表达、合成并释放细胞因子和激素，调控对机械刺激的感应及增殖、分化和矿化。整合素表达水平具有时限变化的特点。应力对成骨细胞代谢及细胞因子的调节应力引起的生长因子的分泌可以是直接通过促进生长因子或在体内促进具有生长作用的激素的分泌，间接促进细胞生长，转化生成因子是成骨细胞中含量较多的生长因子，可以调节成骨细胞的增殖和分化，另一方面，促使合成型胶原纤维连接素，促使成骨细胞合成I型胶原、纤维连接素、骨连接素及蛋白聚糖。Stress and fracture healing: Bone tissue is a viscoelastic solid material with complex mechanical properties. Its structure and function are closely related to its mechanical properties and mechanical environment, which determines that different stress stimuli have different effects on bone metabolism and bone healing. . In terms of the mechanism of stress: Stress affects the cell signal transduction pathway in the process of fracture healing. It can transmit extracellular matrix signals into cells through calcium ion channels, integrins, growth factors, etc. that are expressed on the cell membrane or exist across the membrane. The mechanical signal coupling and cell proliferation of osteoblasts are related to the rise and fall of intracellular and intercellular Ca2+ levels. Integrin is the main substance connecting intracellular and intracellular signals. External tensile stress can induce the physiological and biochemical changes in osteoblasts. Changes, responding and transducing signals, activating gene expression, synthesizing and releasing cytokines and hormones, regulating the induction of mechanical stimuli and proliferation, differentiation and mineralization. Integrin expression levels are characterized by time-dependent changes. The regulation of stress on osteoblast metabolism and cytokines The secretion of growth factors caused by stress can directly promote the secretion of growth factors or hormones with growth effects in vivo, and indirectly promote cell growth. Growth factors with a large content can regulate the proliferation and differentiation of osteoblasts. On the other hand, they can promote the synthesis of collagen fibronectin, and promote the synthesis of type I collagen, fibronectin, osteonectin and proteoglycans by osteoblasts.
在应力作用的方式、时机、种类、大小等方面目前研究认为：间歇性应力刺激较连续性应力刺激更能激发成骨细胞活性；研究认为，骨愈合早期为力学因素促进骨愈合的最有效时期，当骨折愈合恢复原始结构和硬度后，力学因素是骨重塑的唯一因素，骨愈合早期应保证骨折断端间适当的应力和应变，骨愈合早期，轴向载荷产生的压应力能驱动成骨细胞及成纤维细胞向分化成骨方向发展，对骨愈合有利，剪切和扭转载荷产生剪应力，宜造成骨折端动态摩擦，对形成的毛细血管和骨痂有较大伤害，并驱动成纤维细胞增殖，产生纤维组织，不利于骨愈合，在骨愈合中后期各种应力对骨痂的形成和改建均有一定促进作用；骨愈合需适当的生物力学环境或最佳应力水平，只有当骨折端应力水平与愈合区组织刚度互相平衡协调时组织才能良好分化和愈合，应力过大，超过组织承受能力，活体骨将在骨-骨界面或骨-内固定物界面发生反应性表面吸收，骨折端压力减小，导致骨萎缩，且压力越大，骨折端压力减小越迅速，反之，不足以引起弹性变形，组织分化力学诱导降低，难于产生，可能导致骨延迟愈合、骨不连。一般以为骨折端压应力不超过生理体重为宜。In terms of the way, timing, type, and size of stress action, current research shows that intermittent stress stimulation can stimulate osteoblast activity more than continuous stress stimulation; research believes that early bone healing is the most effective period for mechanical factors to promote bone healing , when the fracture heals and restores the original structure and hardness, mechanical factors are the only factors for bone remodeling. In the early stage of bone healing, appropriate stress and strain between the fracture ends should be ensured. In the early stage of bone healing, the compressive stress generated by axial load can drive Osteocytes and fibroblasts develop in the direction of differentiation into bone, which is beneficial to bone healing. Shear and torsional loads produce shear stress, which should cause dynamic friction at the fracture end, which will cause greater damage to the formed capillaries and callus, and drive bone formation. Fibroblasts proliferate and produce fibrous tissue, which is not conducive to bone healing. Various stresses can promote the formation and reconstruction of callus in the middle and late stages of bone healing; bone healing requires an appropriate biomechanical environment or optimal stress level. Only when the stress level of the fracture end and the tissue stiffness of the healing area are balanced and coordinated can the tissue differentiate and heal well. If the stress is too large and exceeds the tissue bearing capacity, the living bone will undergo reactive surface absorption at the bone-bone interface or bone-internal fixation interface. The pressure at the fracture end decreases, leading to bone atrophy, and the greater the pressure, the faster the pressure at the fracture end decreases. On the contrary, it is not enough to cause elastic deformation, and the mechanical induction of tissue differentiation is reduced, which is difficult to produce, and may lead to delayed bone union and nonunion. It is generally believed that the compressive stress at the fracture end should not exceed the physiological body weight.
微动与骨折愈合方面：骨折端微动与应力密切联系，根据Wollf定律及近来的许多研究证实，骨折端可控制性的适宜微动能促进骨痂的形成和钙化，加速骨折愈合，在微动的频率、时机、量等方面目前研究认为：低频率的轴向方向上的微动对骨折愈合有利，早期控制性微动能促进骨折愈合，晚期(4-6周)产生的微动易损伤骨折部位血管网，延迟骨折愈合。In terms of fretting and fracture healing: the fretting of the fracture end is closely related to the stress. According to Wollf's law and many recent studies, it has been confirmed that the controllable and appropriate fretting of the fracture end can promote the formation and calcification of the bone callus, and accelerate fracture healing. The frequency, timing, and amount of movement, etc. The current research believes that low-frequency micro-movement in the axial direction is beneficial to fracture healing, early-stage controlled micro-motion can promote fracture healing, and late-stage (4-6 weeks) fretting is easy to heal. Damage the vascular network at the fracture site and delay fracture healing.

一种骨科临床应用的弹性内固定系统及可调压固定棒，采用1个或2个上述可调压固定棒，与2个以上单棒型、双棒型或解剖型固钉装置组合成弹性内固定系统。An elastic internal fixation system and pressure-adjustable fixing rods for orthopedic clinical application, using one or two above-mentioned adjustable pressure fixing rods, combined with more than two single-rod type, double-rod type or anatomical nail fixing devices to form an elastic Internal fixation system.
本发明首先提供了一种改进的调压固定棒，然后由调压固定棒与单棒型、双棒型或解剖型固钉装置等组合出上述弹性内固定系统。本发明的有益效果在于以下几个方面：The present invention firstly provides an improved pressure-regulating fixing rod, and then combines the pressure-regulating fixing rod with a single-rod type, double-rod type or anatomical nail-fixing device to form the above-mentioned elastic internal fixation system. The beneficial effects of the present invention lie in the following aspects:
首先，本发明可调节压力的弹性内固定系统的调压固定棒较原来的固定棒相比较，在主体构造方面几乎完全重新设计，从原先的简单连接棒，变更为调节杆、滑动螺套、弹性装置、单向及双向调压装置、固定杆的组合，这种微动装置可减少脊柱固定装置的应力遮挡，避免骨质疏松，避免固定棒的疲劳断裂。First of all, compared with the original fixed rod, the pressure-regulating fixed rod of the elastic internal fixation system with adjustable pressure in the present invention is almost completely redesigned in terms of main body structure. The combination of elastic device, one-way and two-way pressure regulating device, and fixed rod, this kind of micro-movement device can reduce the stress shielding of the spinal fixation device, avoid osteoporosis, and avoid the fatigue fracture of the fixed rod.
其次，双向调压装置更加精确，可根据具体患者情况需要实现向上或向下调压，从而方便有效地实现调压的优点；Secondly, the two-way pressure regulating device is more accurate, and can realize upward or downward pressure regulation according to the specific patient's needs, so as to realize the advantages of pressure regulation conveniently and effectively;
最后，调节杆、固定杆可设为与人体骨骼弧度相一致的弧状，减少了手术的预弯步骤，操作更加方便；Finally, the adjustment rod and the fixing rod can be set in an arc shape consistent with the curvature of human bones, which reduces the pre-bending steps of the operation and makes the operation more convenient;
综上，使用本发明的弹性内固定系统进行固定，骨骼在轴向压力下，通过骨骼上的骨螺钉、调节杆和固定杆上下端，促使调节杆下移加压，压缩弹性胶囊或弹簧，由于调节杆可微动下移，随之带动并控制骨折骨骼也传导应力，受骨折端应力作用，可刺激骨折端骨痂生成，避免骨折端产生应力遮挡。当骨折骨骼受到轴向应力时，可刺激骨折端骨痂生成，避免外固定架应力遮挡形成骨质疏松，可加快骨折愈合速度，增加愈合骨质的强度，有效预防固定装置断棒的发生。In summary, using the elastic internal fixation system of the present invention for fixation, the bone is under axial pressure, through the bone screw on the bone, the adjustment rod and the upper and lower ends of the fixation rod, the adjustment rod is pushed down to pressurize, and the elastic capsule or spring is compressed. Since the adjusting rod can move down slightly, it drives and controls the fracture bone to conduct stress, and is affected by the stress of the fracture end, which can stimulate the formation of callus at the fracture end and avoid stress shielding at the fracture end. When the fractured bone is subjected to axial stress, it can stimulate the formation of callus at the fracture end, avoid the stress shielding of the external fixator to form osteoporosis, accelerate the fracture healing speed, increase the strength of the healing bone, and effectively prevent the occurrence of broken rods of the fixation device.
