所属技术领域Technical field
本发明涉及医疗器械技术领域，特别是涉及一种脊柱畸形手术矫正装置。The invention relates to the technical field of medical instruments, in particular to a spinal deformity surgical correction device.
背景技术Background technique
目前国内进行脊柱矫正技术主要是通过畸形相关节段椎弓根螺钉及连杆技术进行，由于脊柱畸形手术是高风险手术，国内常用技术的手术时间长，使用节段椎弓根螺钉及连杆技术易伤及周围相关组织并发症多。利用力传感器及多阶段同时矫正装置等可以减少手术并发症，缩短手术时间。随着材料科学、传感器技术及生物力学的迅猛发展，各种医疗器械和设备层出不穷，力传感器已经开始广泛应用，医生可以根据辅助器械显示的多个节段的力学信号来判断脊柱畸形矫正的程度以及是否会损坏骨质。常规手术中，需要将畸形相关节段的椎体植入椎弓根螺钉并连接连杆，依靠人力提拉和旋转来完成畸形的矫正，但此过程不能保证畸形彻底矫正，同时矫正过程中可能损伤骨质及其它软组织，因此需要一个脊柱畸形矫正装置，保证脊柱畸形矫正的彻底性，同时尽量降低其它组织损伤的可能性。At present, domestic spinal correction technology is mainly carried out through deformity-related segmental pedicle screws and connecting rods. Since spinal deformity surgery is a high-risk operation, the operation time of domestic commonly used techniques is long, and segmental pedicle screws and connecting rods are used. The technique is easy to injure and the surrounding related tissues have many complications. The use of force sensors and multi-stage simultaneous correction devices can reduce surgical complications and shorten operation time. With the rapid development of material science, sensor technology and biomechanics, various medical devices and equipment emerge in an endless stream. Force sensors have begun to be widely used. Doctors can judge the degree of spinal deformity correction based on the mechanical signals of multiple segments displayed by auxiliary devices. and whether it will damage the bone. In conventional surgery, it is necessary to implant pedicle screws and connect connecting rods in the vertebral body of the deformity-related segment, and rely on manual lifting and rotation to complete the correction of the deformity. However, this process cannot guarantee the complete correction of the deformity. Damage to bone and other soft tissues, so a spinal deformity correction device is needed to ensure the thoroughness of spinal deformity correction while minimizing the possibility of other tissue damage.
