Description
技术领域technical field
本实用新型涉及骨科手术器材技术领域，尤其是一种PFNA股骨近端髓内钉器械。The utility model relates to the technical field of orthopedic surgery equipment, in particular to a PFNA proximal femoral intramedullary nailing instrument.
背景技术Background technique
股骨转子间骨折是老年人的一种常见骨折。在临床上存在以下三个特点：一是患者多为高龄，全身情况差，并伴有多种内科合并症，在骨折后这些合并症往往都有加重，导致疾病治疗难度加大，病死率较高；二是骨质量，多有明确的骨质疏松，导致骨折固定可靠性降低；三是骨折类型多为粉碎不稳定性骨折，易发生术后髋内翻，头颈短缩及内固定失效、断裂。治疗上尽早外科手术固定已成共识，其关键是在骨折愈合前期提供一种坚强且稳定的桥连装置，使患者尽早下地活动，减少病死率。在对股骨近端骨折进行固定时，近端断裂段必须对准股骨轴定向固定，即保持防位移和旋转固定。Intertrochanteric fracture is a common fracture in the elderly. Clinically, there are the following three characteristics: First, most patients are elderly, with poor general conditions, and a variety of medical complications. Second, bone quality, often with definite osteoporosis, leads to reduced reliability of fracture fixation; third, fracture types are mostly comminuted unstable fractures, prone to postoperative coxa varus, head and neck shortening and internal fixation failure, fracture. In terms of treatment, early surgical fixation has become a consensus. The key is to provide a strong and stable bridging device in the early stage of fracture healing, so that patients can get off the ground as soon as possible and reduce the mortality rate. When fixing proximal femoral fractures, the proximal fractured segment must be fixed in alignment with the femoral axis, that is, to maintain anti-displacement and rotation fixation.
目前临床上在针对股骨、胫骨骨干中段骨折的特定髓内钉手术中所用的近端固定器械在使用过程中卡圈易脱落，影响使用，远端固定器的定位杆在定位过程中不够稳定容易松动，因此现有髓内钉远端的远端定位杆的结构在临床使用上存在着弊病。At present, in the specific intramedullary nail surgery for femoral and tibial shaft fractures, the proximal fixation device is easy to fall off during use, which affects the use, and the positioning rod of the distal fixation device is not stable enough during the positioning process. Loose, so the structure of the far-end positioning rod at the far-end of the existing intramedullary nail has disadvantages in clinical use.
