Description
Technical field
This utility model relates to the technical field of medical apparatus and instruments, especially a kind of multiaxis orthopaedics dynamic growth rod.
Background technology
In modern medicine, be used for the treatment of in the operation of child's scoliosis, be placed on the supplemental support rod in patient body, can not extend along with child's growth, must again perform the operation and again place again suitable supplemental support rod using certain degree, in the process of growing up, needs of patients carries out Repeated Operation, to patient, has brought very large misery.
Utility model content
In order to overcome the deficiency of existing technology, this utility model provides a kind of multiaxis orthopaedics dynamic growth rod.
This utility model solves the technical scheme that its technical problem adopts: a kind of multiaxis orthopaedics dynamic growth rod, comprise 2 pitmans, also comprise adapter, what in described adapter, be parallel to each other is provided with a through hole and a taper hole, in described through hole, be provided with a wherein pitman, also comprise a taper resilient sleeve, the monolateral tapering of described taper resilient sleeve is 2 °-10 °, described taper elasticity sleeve is provided with a groove to direction, described taper resilient sleeve is in axial direction also provided with at least one groove, the notch of described groove is arranged on the osculum of taper resilient sleeve, described taper resilient sleeve is set on another root pitman, described another root pitman being arranged in taper hole by taper resilient sleeve interference fit, also comprise block, described block is through 2 pitmans and push down taper resilient sleeve and be connected with adapter.
According to another embodiment of the present utility model, further comprise that the sidewall of described through hole is provided with hole, described in be arranged on pitman in through hole and be fixed by the locking nut being arranged in hole.
The beneficial effects of the utility model are, a kind of dynamic growth supplemental support rod of the child's for the treatment of orthopaedic disease is provided, by simple tapered configuration, dynamic growth rod can be increased along with patient's growth, continue performance interconnect function, until skeleton growth is sound, second operation and the Repeated Operation of having avoided patient to cause due to growth, reduced patient's misery, and also solved single shaft dynamic growth rod in operation due to the difficulty that can not implant corresponding position and bring.
