Operative treatment at present for long bone shaft fracture adopts the fixationes such as intramedullary pin, steel plate, external fixer usually, in internal fixation by intramedullary pin, general intramedullary pin is provided with far, the locking nail hole of near-end, make pinning can through far away, the proximal locking nail hole on long tube cortex and intramedullary pin, reach the effect of locking, there is the function making sclerite para-position to line, fix, support certain gravity, in order to growth of spur union of fracture.Use this intramedullary pin, the pinning at far away, nearly two ends is needed to be connected and fixed, during installation, intramedullary pin is inserted after in pulp cavity and hole again, well cannot find the position of locking nail hole on corresponding intramedullary pin at long bone cortex far-end accurately, increase the weight of the burden of surgical operation.
Summary of the invention
The object of this invention is to provide a kind of band magnetic intramedullary pin, at intra medullary nail far-end, place is provided with magnetic part, because the locking nail hole distance of magnetic part and far-end is fixing, according to locking nail hole position, accurate locating distal place, magnetic part position, can greatly facilitate the use of doctor.
For achieving the above object, the technical solution adopted in the present invention is: comprise rivet nut, rivet nut is the major axis pipe that an inside is provided with through hole, the near-end of rivet nut and far-end are equipped with the locking nail hole that multiple radial direction along rivet nut is arranged, the far-end of rivet nut is embedded with the magnetic magnetic part of band for locking nail hole position, locating distal place.
Preferably, described rivet nut comprises integrated main body and block, and block is positioned at the end of rivet nut far-end, and the junction of main body and block is provided with the storage tank adapted with magnetic part shape, and magnetic part is embedded in storage tank by block.
Preferably, described magnetic part is the magnetic annulus that an outer ring is provided with platform, and the shape of storage tank and the shape of described magnetic annulus adapt.
Preferably, the end of described rivet nut near-end is provided with the link slot for the outer nailing device of connector.
Preferably, described rivet nut once prints manufacture by metal dust by 3D printing technique and forms.
After adopting technique scheme, the present invention has following good effect:
(1) band magnetic intramedullary pin of the present invention, at band, magnetic intra medullary nail far-end place is provided with magnetic part, because the locking nail hole distance of magnetic part and far-end is fixing, according to locking nail hole position, accurate locating distal place, magnetic part position, can greatly facilitate the use of doctor;
(2) magnetic part in the present invention is embedded in rivet nut, make magnetic part not with direct body contact, the intensity of whole rivet nut biocompatibility issues can not be caused, and magnetic part is embedded in the far-end of intramedullary pin, so can not be reduced because of magnetic part hollow-core construction;
(3) magnetic part in the present invention is the annulus that an outer ring is provided with platform, the ingehious design of platform makes magnetic part be placed in rivet nut, and rivet nut is by 3D printing technique printing shaping, success rate is high, decrease the complicated course of processing, few cutting can be realized, close without machining, increase work efficiency, reduce the wasting of resources.
