本实用新型涉及医疗手术设备领域，特别是一种髌骨脱位手术髌骨侧韧带钻孔固定定位器系统。The utility model relates to the field of medical operation equipment, in particular to a patella lateral ligament drilling and fixing locator system for patella dislocation operation.
背景技术Background technique
髌骨脱位手术需要在髌骨侧钻孔固定一侧韧带是常规术式，目前常采用手摸心会或者在透视下定位，经常出现髌骨钻孔处L形隧道不能相通或者偏斜的情况导致韧带不能顺利引入，并且容易造成骨折影响手术效果；需要有一种辅助工具引导定位，尤其是对于初学者。Patellar dislocation surgery needs to drill a hole on the side of the patella to fix the ligament on one side. It is a routine operation. At present, manual palpation or fluoroscopy is often used for positioning. Often, the L-shaped tunnel at the patella drill hole cannot communicate or is deflected, resulting in ligament failure. It is introduced smoothly, and it is easy to cause fractures and affect the surgical effect; an auxiliary tool is needed to guide the positioning, especially for beginners.
同时，髌骨脱位的治疗目前对于青少年儿童是一个热点，大家越来越重视早期髌骨脱位的治疗。而限制髌骨脱位的一个重要结构就是膝关节内侧髌股韧带，这成为目前治疗髌骨脱位的一个重要手术步骤。在手术过程中，这个髌股韧带一侧需要固定在髌骨上，通常采用的办法就是在髌骨上横向和垂直钻孔形成一个或者两个“L”形隧道以便韧带穿入，横向和垂直的骨道在髌骨上，最好是在中部相通。也有手术医生采用髌骨内侧置入缝合铆钉来避免钻孔发生的失误，是利用铆钉上带的缝线将韧带缝合于局部，依靠缝线的力量初始固定。但这无疑增加了患者的手术费用，而且是金属铆钉，无法二次取出，对患者心理有一定影响。对于大多数医院来说采用钻孔技术固定韧带是一个可靠经济的方法。At the same time, the treatment of patellar dislocation is currently a hot spot for adolescents and children, and everyone pays more and more attention to the treatment of early patellar dislocation. An important structure limiting patellar dislocation is the medial patellofemoral ligament of the knee joint, which has become an important surgical step in the treatment of patellar dislocation. During the operation, one side of the patellofemoral ligament needs to be fixed on the patella. The usual method is to drill holes horizontally and vertically on the patella to form one or two "L"-shaped tunnels for the ligament to penetrate. The tract is on the patella, preferably in the middle. There are also surgeons who place suture rivets on the inside of the patella to avoid mistakes in drilling. They use the sutures on the rivets to suture the ligament locally and rely on the strength of the sutures for initial fixation. However, this undoubtedly increases the patient's operation cost, and it is a metal rivet, which cannot be taken out again, which has a certain impact on the patient's psychology. Fixation of the ligament using the drilling technique is a reliable and economical method for most hospitals.
现有技术虽然在一定程度上解决了髌骨侧韧带固定的问题，但是有这样那样的问题，尤其是对于经验欠缺的手术者，容易出现髌骨侧韧带固定失误的问题，常见问题有：髌骨垂直骨道进入关节面，损伤髌骨软骨面。还有横向骨道偏前，容易造成骨道破裂固定失败。Although the prior art has solved the problem of patellar lateral ligament fixation to a certain extent, there are such and other problems, especially for inexperienced operators, the problem of fixation error of patellar lateral ligament is prone to occur. Common problems include: The tract enters the articular surface and damages the cartilage surface of the patella. In addition, the transverse bone tunnel is forward, which may easily cause fracture and fixation failure of the bone tunnel.
