The utility model relates to a computer-aided design of individualized sternal prosthesis, which comprises a prosthetic sternal handle and a prosthetic sternal body. The prosthetic sternal body is vertically provided with multiple fixing channels, and a clavicular connection channel designed at the position between clavicles at the top of the prosthetic sternal handle is used to penetrate the reconstructed interclavicular ligament; a plurality of sternoclavicular joints at the top of the prosthetic sternoclavicular handle are designed to penetrate the reconstructed sternoclavic The perforations of the joint ligament, the Sternocostal joints on both sides of the sternopedicle were designed to pass through the reconstructed Sternocostal ligaments, and the inert lines connecting the prosthesis and the ribs were designed at the Sternocostal joints on both sides of the sternopedicle. The beneficial effect of the needle of the utility model is that the structure design of the sternal prosthesis is reasonable, multiple channels are arranged at the edge of the sternal handle of the prosthesis connecting with the clavicle and rib, which perfectly matches the patient's thoracic structure, and the ligament connection solves the problem of limited range of upper limb movement after operation.

计算机辅助设计个体化胸骨假体
本技术属于骨外科截骨矫形器材领域,尤其涉及计算机辅助设计个体化胸骨假体。
技术介绍
胸骨位于胸前壁正中,后方为心包及大血管,为一上宽下窄、前扁后凹的扁骨,分为胸骨柄、胸骨体和剑突三部分。另外因锁骨的胸骨关节面与胸骨柄的锁骨切迹及第1肋软骨的上面共同构成的胸锁关节可做各个方向的微动运动,体现为锁骨外侧端的上提、下降和前后运动,此外,尚能做轻微的旋转运动。因此胸锁关节关系到患者上肢的活动范围,影响患者正常生活。某些严重胸部疾病(如交通事故、肿瘤等)侵犯胸骨时,需要行广泛胸骨切除术,常需进行胸骨或胸壁重建。在临床实践中,胸壁的重建主要有骨水泥联合钢板或钛网、同种异体骨移植等,虽然解决了胸壁重建的问题,但假体使用年限、假体强度、骨吸收等弊端十分明显。随着计算机辅助骨科的日益兴起,有学者应用计算机及3D打印技术,设计并生产了部分标准化的胸骨假体。这类假体并未考虑到患者的年龄、疾病特点、胸锁关节的微动运动等因素的影响,缺乏精确的量化指标,使术后患者上肢运动受到较大范围的制约,影响患者正常生活。同时因部分成品的胸骨假体体积过大,术中安放时会增加手术 ...
