Abstract

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双环式枢锥齿状突瞄准器。包括空心导向管以及连接在空心导向管上的瞄准装置,所述瞄准装置包括同心设置的内套环和外套环,所述内套环和外套环以及空心导向管之间通过十字交叉的转轴连接,所述转轴均由可相对旋转并同轴设置的内套管和外套管套装而成。该瞄准器结构简单、使用方便、定位准确快速,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。
The invention relates to a medical instrument, in particular to a double-ring type pivot cone odontoid sighting device for guiding hollow screw locating in pivot cone odontoid fracture treatment. The double-ring type pivot cone odontoid sighting device comprises a hollow guiding pipe and a sighting device connected to the hollow guiding pipe. The sighting device comprises an inner sleeve ring and an outer sleeve ring which are arranged concentrically. The inner sleeve ring, the outer sleeve ring and the hollow guiding pipe are connected through cross rotating shafts. The rotating shafts are formed by inner sleeve pipes and outer sleeve pipes in a sleeved mode, and the inner sleeve pipes and the outer sleeve pipes can rotate relatively and are arranged coaxially. The sighting device is simple in structure, convenient to use and accurate and quick in locating, the device can be used for guiding a Kirschner wire to be located accurately in pivot cone odontoid fracture treatment, accordingly, operation quality is improved, operation errors are reduced, and the pain of a patient is lowered.
