Description
Technical field
The present invention relates to fracture fixation apparatus technical field, specifically, being that one kind is hollow locks exterior fixing rack and answers
With the fracture fixation device of the hollow locking exterior fixing rack.
Background technology
At present, doctor generally treats fracture patient using exterior fixing rack or interior fixedly locked steel plate.
Interior fixedly locked steel plate fits on bone inside human muscle, is fixed on two sections of bones by nail
On interior fixedly locked steel plate, two sections of bones are positioned, nail is threadedly coupled with interior fixedly locked steel plate, belongs to and be rigidly connected, interior
It is less likely to occur to loosen between fixedly locked steel plate and nail.The problem of being existed using the therapeutic modality of interior fixedly locked steel plate
It is：, it is necessary to which doing second operation takes out interior fixedly locked steel plate after union, extra actual bodily harm is caused to patient, and hold
The economic pressures received are big.
Exterior fixing rack is outside human muscle, and nail is through exterior fixing rack and muscle and relies on two sections of bones
On.After union, nail need to only be taken out, be not required to second operation, the injury caused to patient is small, and economic pressures are small.
But, the problem of being existed using the therapeutic modality of existing exterior fixing rack is：Nail and outer fixation through exterior fixing rack
Support is not connected through a screw thread, and is not belonging to be rigidly connected, and causes easily to loosen between exterior fixing rack and nail, fracture
Healing is slow, is unfavorable for the rehabilitation of patient.
Based on above mentioned problem, being badly in need of one kind at present can be rigidly connected nail, can make two sections of bones of fracture relative again
The exterior fixing rack of motion.
The content of the invention
First technical problem to be solved by this invention be：There is provided a kind of outside human muscle rigid with nail
The hollow locking exterior fixing rack of connection.
Second technical problem to be solved by this invention be：Offer is a kind of can to make two sections of bone relative motions of fracture
Fracture fixation device.
