Abstract

The invention relates to a rib generator. The generator comprises a guide rod and an extender, and the two ends of the guide rod are fixedly arranged on a first fixing plate and a second fixing platerespectively; a movable plate is hinged to the second fixing plate through a hinge, and the extender comprises a threaded rod, a sleeve which sleeves the threaded rod and a sliding block; one end of the sleeve is connected with the first fixing plate, and the other end of the sleeve is fixedly arranged on the movable plate; the sliding block is axially connected with the threaded rod, and a manipulation rod is connected to the back end of the threaded rod. The rib generator is simple and reasonable in structure, convenient to operate and use, good in stability and convenient to adjust; the surgical requirement of rib extension is greatly met, the extension direction can be changed by adjusting screws on the hinge, the rib generator crosses original defect ribs, distraction osteogenesis continues, finally the requirement that redundant ribs are regenerated for other autogenous bone transplantation is met, and the difficult problem of the medical field is solved.

Description

technical field [0001] The invention relates to an instrument that can be used to treat rib defects and regenerate excess bone, in particular to a rib generator, which belongs to the field of medical instruments. Background technique [0002] At present, there is no extender for rib distraction osteogenesis in the medical field, and the missing ribs are replaced by steel plates. Absence of ribs is common: the absence of ribs after trauma, the absence of bone tumor resection and congenital absence. At present, the most common correction is to use steel plates, nass pumps and titanium alloys. Although they can be treated, the tissues that cannot reach their own tend to be more physiological; while rib distraction osteogenesis can produce normal ribs. However, the lengthening of the ribs requires a certain degree of curvature and hardness. In addition, there are many diseases that lack bone tissue in humans. How to regenerate more bone or in the process of rib distraction ost...
