Description
技术领域technical field
本发明涉及骨科内固定手术用的器材领域，具体涉及一种骨钉。The invention relates to the field of equipment used in orthopedic internal fixation operations, in particular to a bone nail.
背景技术Background technique
传统的骨外科手术，通常是先将病变部位进行清理、减压等，然后植入骨钉，通过骨钉直接或与配套器械配合将相邻近的两个病变部位固定，形成刚性连接。如在腰颈椎内固定手术，会将椎弓根钉植入相邻的椎体，再用连接棒作固定连接； 又如肢体骨折时，会用骨钉，穿过接骨板，植入待接驳的骨内，同样形成刚性固定连接。据最新的临床发现，相邻近的病变部位，在固定后若能保持稍微（约0.5毫米）的相对活动，能刺激创面的加快痊愈； 而且其愈合速度及效果，比完全刚性固定，没有相对活动的创面愈合效果好得多。但是由于现有的骨钉大多为基于传统理论设计，金属整体加工产品，整个骨钉呈刚性，无法做到微小位移，不能促进病变部位快速良好的愈合。In traditional orthopedic surgery, the lesion is usually cleaned and decompressed first, and then bone nails are implanted, and two adjacent lesion areas are fixed directly or with supporting instruments through the bone nails to form a rigid connection. For internal fixation of the lumbar and cervical spine, pedicle screws will be implanted into adjacent vertebral bodies, and then connecting rods will be used for fixed connection; for example, when a limb is fractured, bone screws will be used to pass through the bone plate and implanted The barge bone also forms a rigid fixed connection. According to the latest clinical findings, if the adjacent lesions can maintain a slight (about 0.5mm) relative movement after fixation, it can stimulate the wound to heal faster; Active wounds heal much better. However, because most of the existing bone nails are designed based on traditional theories, the metal integral processing products, the whole bone nail is rigid, cannot achieve small displacement, and cannot promote fast and good healing of the lesion.
发明内容Contents of the invention
本发明针对上述提到的现有技术中的骨钉只能刚性固定病变部位这一技术问题，提供一种结构简单，生产简便，能够广泛使用，确保病变部位能够做出细微相对活动的柔性连接段骨钉。The present invention aims at the above-mentioned technical problem that the bone nails in the prior art can only rigidly fix the diseased part, and provides a flexible connection with simple structure, easy production and wide use, which ensures that the diseased parts can be slightly moved relative to each other. Segment bone nail.
其采用的技术方案是：一种骨钉，包括钉头和与钉头连接的钉身，所述的钉身包括有硬质钉身本体和供钉身与钉头作相对摆动的柔性连接段；所述柔性连接段的首尾两端分别连接所述的钉头和硬质钉身本体。The technical solution adopted is: a bone nail, including a nail head and a nail body connected with the nail head, and the nail body includes a hard nail body body and a flexible connecting section for relative swing between the nail body and the nail head ; The first and last ends of the flexible connecting section are respectively connected to the nail head and the hard nail body.
进一步地，所述柔性连接段为弹簧。Further, the flexible connecting section is a spring.
