Description

枢椎齿状突瞄准装置 Odontoid sighting device

技术领域 FIELD

[0001] 本发明涉及一种医疗器械,具体的说是一种用于枢椎齿状突骨折治疗中引导空心螺钉定位的枢椎齿状突瞄准装置。 [0001] The present invention relates to a medical device, specifically for a odontoid fractures guide odontoid hollow screw positioned sighting device.

背景技术 Background technique

[0002]枢椎齿状突骨折是颈椎的常见骨折,占颈椎骨折的10%〜14%。 [0002] odontoid fractures are common fractures of the cervical spine, accounting for 10% ~ 14% of cervical spine fracture. 未经治疗或治疗不当造成的齿状突骨折不愈合率为42-72%,且同时存在潜在的寰枢椎不稳定,可能导致脑干、 脊髓或神经根的急性或慢性损伤,引起严重的四肢瘫痪、呼吸功能障碍,甚至死亡。 Odontoid fractures without treatment or improper treatment of non-healing rate of 42-72%, and both the potential atlantoaxial instability may lead to acute or chronic damage to the brain stem, spinal cord or nerve roots, causing serious quadriplegia, respiratory dysfunction, and even death. 故对枢椎齿状突骨折的患者应积极治疗。 Therefore, in patients with odontoid fractures should be actively treated. 自1洲1年首次报道采用螺钉直接内固定治疗齿状突骨折以来,临床实践已证实,与传统的治疗方法相比,此技术不仅可以重建寰枢关节的稳定性, 还能最大限度地保留寰枢关节的活动性,手术创伤小,骨折愈合率高,并明显改善患者生活质量,认为该技术是齿状突骨折手术治疗的首选。 1 year since the continent was first reported use of internal fixation screws directly dens fractures, clinical practice has been confirmed, compared with traditional treatments, this technology can not only rebuild the stability of atlantoaxial joint, but also to maximize the retention atlantoaxial joint mobility, surgical trauma, fracture healing rate, and significantly improve the quality of life of patients, that the technology is odontoid fracture treatment of choice. 虽然前路螺钉内固定治疗齿状突骨折的疗效已在临床上得到了肯定,但以往由于主要凭经验操作,导向克氏针需要反复调整,手术随机性大,甚至可能产生严重的并发症,包括螺钉断裂、骨折移位、骨折不愈合或螺钉攻出齿状突而伤及脊髓等。 Although the anterior screw fixation of odontoid fracture efficacy has been affirmed in the clinic, but ever since the main rule of thumb operation, guiding Kirschner need to repeatedly adjust, surgical random, and may even cause serious complications, It comprises a screw fracture, displaced fracture, nonunion or tapped screw dens and spinal cord injuries. 中国专利2012102768399公开了一种《枢椎齿状突螺钉瞄准器》,其采用螺母调节安装在空心导向管上的两根伸缩连杆从而改变空心导向管的指向,两伸缩连杆连接在微调控制板上,微调控制板通过球关节与支撑杆连接。 Chinese Patent No. 2012102768399 disclosed a "screw odontoid sight", which employs two telescopically adjustable rod nut mounted on a hollow guide tube thereby changing the directivity of the hollow guide tube, the telescopic connecting rod in the two fine control board, trim panel is connected to the support rod by a ball joint. 这种枢椎齿状突螺钉瞄准器可以用于枢椎齿状突骨折治疗中引导克氏针精确定位,从而提高手术质量,减少手术失误, 降低病人的痛苦。 Such odontoid screws may be used to sight odontoid fractures precise positioning guiding Kirschner wire, thereby improving the quality of surgery, reduce operation errors and reduce the suffering of the patients. 但在手术过程中,由于需要调节的位置众多,并且调节各调节点相互关联,往往需要反复调整才能达到要求,影响手术进度。 But during surgery, because of the large need to adjust the position and adjust each adjusting point interrelated and often require repeated adjustments in order to meet the requirements, affect the progress of surgery. 另外,螺母调节的伸缩连杆的长度难以精准计量,伸缩连杆连接在微调控制板上的位置也不确定,这种枢椎齿状突螺钉瞄准器不能用坐标数据记录位置,无法重复再现以前手术中的定位。 Further, the length of the telescopic rod adjusting nut is difficult to accurately measure, the telescopic connecting rod in the position of the fine control board is not determined, this screw odontoid sight can not coordinate data recording position, the reproduction can not be reused before surgery positioning.
