Description
Technical field
This utility model relates to vertebral pedicle puncture technical field, particularly the external localizer of a kind of pedicle channel.
Background technology
Along with minimally invasive spine surgical development, accounting is from 10% developing into current 48% before 10 years, and have the trend exceeding spinal column open operation, the nearly all Grade A hospital in the current whole nation is all carrying out minimally invasive spine surgical, market range of application is wide, benefit is obvious, Minimally Invasive Surgery concept is rooted in the hearts of the people, and more for attraction patient is selected this type of operation plan.Common minimally invasive spine surgical has: vertebroplasty, percutaneous vertebral body internal fixation by nail-stick system art, MED, foramen intervertebrale lens etc., percutaneous puncture pedicle channel again after all needing preoperative, Intraoperative position accurately.Traditional location adopts Kirschner wire, syringe needle or grid transparent plastic paper to lie in art district skin surface, plane positioning is carried out under C arm X-ray machine, debugging, length consuming time (about 20 minutes repeatedly, account for total operation 1/3), radiocontamination weight, belonging to two dimensional surface location instead of space orientation, is the localization method with " blindly "; Modern " electron probe " technology, probe carries out three-dimensional operation guiding system by computer after computer registration, navigate visual in image, but still need repeatedly to simulate puncture and debug, until accurate positioning, can operation safety be improved but need repeatedly debug, length consuming time, and equipment price is expensive, Difficulty, the hospital that the whole nation can be carried out cans be counted on one's fingers.
Utility model content
The purpose of this utility model is the external localizer of pedicle channel providing a kind of structure simple, easy to use to overcome above-mentioned deficiency.
This utility model is achieved in that the external localizer of a kind of pedicle channel, it is characterized in that: it comprises the rectangle foldable frame base being provided with longitudinal adjusting rod and fixed bar, described longitudinal adjusting rod has two and each longitudinal adjusting rod is all socketed with two three-dimensional localization framves, described three-dimensional localization frame comprises one end and is socketed in sliding bar on longitudinal adjusting rod, inverted T shape lateral adjustments bar, one end and the hinged clamper connecting rod of inverted T shape lateral adjustments bar, clamper, described sliding bar is transversely provided with the sliding tray slided for inverted T shape lateral adjustments bar, one end of described clamper and the other end of clamper connecting rod are threaded connection, the end face of described clamper one end is circumferentially provided with angle index, the hinged place of described inverted T shape lateral adjustments bar and clamper is provided with angle index.
Described longitudinal adjusting rod is provided with scale.
