The technical solution adopted in the utility model further comprises:
Further, described bulb is connected to the lower opening of adapter, is matched in clearance between adapter inwall and the bulb of under shed.
Further, the under shed internal diameter of described adapter is more than the diameter of bulb, and bulb stretches in adapter under shed.
Further, described pin has two.
Further, described pin is fixed by welding on adapter.
Further, described pin is threadedly secured on adapter.
Further, one end of described pin is provided with screw thread.
Further, described pin has one.
Further, described connecting hole is through hole.
Compared with currently existing scheme, what this utility model was obtained has the technical effect that interior suspension type dynamic support pedicle nail of the present utility model combines up-to-date academic viewpoint, button is connected by the mode hung in using with adapter, both installation part had been saved, reach to reduce the beneficial effect of production cost, improve again the stability that pedicle nail supports, more close and meet clinical practice use requirement.
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
