Description

骨科手术用导向机构
技术领域
本发明涉及医疗器械制造技术领域，特别涉及一种骨科手术用导向机构。
背景技术
骨科手术特别是脊柱手术，常需要从一侧入路处理对侧椎体或椎间隙，如行TLIF手术时，为了能够从单侧入路处理对侧椎间隙。现行的方法是先使用直形工具处理同侧间隙，再使用弯头工具处理对侧间隙；再如行椎体后凸成形术时，为了实现对整个椎体进行复位和填充骨水泥，现行的方法是从两侧椎弓根分别穿刺后进行复位和填充骨水泥。无论是使用直形、弯头工具处理椎间隙，还是双侧椎弓根穿刺对椎体复位和填充骨水泥，都延长了手术时间，增加手术难度，增加患者痛苦。
发明内容
本发明的目的是克服现有技术存在的缺陷，提供一种结构简单，性能可靠，可使脊柱手术从单侧入路后可对对侧进行处理，降低手术难度，减少手术时间，降低患者痛苦的骨科手术用导向机构。
实现本发明目的的技术方案是：一种骨科手术用导向机构，具有准直管和导向管；所述准直管套接在导向管外侧；所述导向管由依次连接的第一直行部、弯曲部和第二直行部组成。
上述技术方案所述导向管的为超弹性态的镍钛合金导向管。
上述技术方案所述镍钛合金导向管的奥氏体转变终了温度Af为5-15℃。
采用上述技术方案后，本发明具有以下积极的效果：
本发明结构简单，性能可靠，可使脊柱手术从单侧入路后可对对侧进行处理，降低了手术难度，减少了手术时间，降低了患者痛苦。
