Abstract
The invention discloses a kind of dissection lockings of distal femur to overhaul steel plate, including steel plate ontology；It is provided with nail hole on the steel plate ontology；The diameter of the nail hole is more than the diameter of the nail hole for the dissection lockplate for being originally fixed on distal femur；The distal end setting of the steel plate ontology holds section；The holding section and described this body by integral forming of steel plate；Nail hole is arranged in the holding section.The steel plate of the present invention dramatically increases the hold of bone tissue after nail hole and nail diameter increase, effectively solves the problems, such as conventional steel sheet for can not effectively be fixed when overhauling.
Description
Technical field
The invention belongs to medical instruments field, it is related to the steel used when bone nonunion revision procedure after a kind of Methods for Distal Femoral Fractures
Plate.
Background technology
Methods for Distal Femoral Fractures accounts for about the 6% of whole body fracture, and to close on articular fracture, effect of conservative treatment is poor, most
Scholar advocates operative treatment, fixed in lateral approach dissection locking steel plate, is increasingly becoming treatment Methods for Distal Femoral Fractures classics
Internal fixation method.Although operative treatment achieves good effect, Treatment of nonunion, interior fixation has report when being broken in document
Road.For the patient of interior fixed fracture, again when row revision procedure, since outside plate is dissection lockplate, selection is same again
When a kind of shape steel plate, often it is placed on and operation same position for the first time.Since steel plate is positioned over same position, locking nail
Can be placed in for the first time operation same position, this may result in fixation it is insecure, or even again operative failure the problem of.
Invention content
The technical problem to be solved in the present invention is to provide a kind of dissection lockings of distal femur to overhaul steel plate, can significantly improve
The firmness of Interal fixation when revision procedure.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：Steel plate is overhauled in distal femur dissection locking, is wrapped
Include steel plate ontology；It is provided with nail hole on the steel plate ontology；The diameter of the nail hole, which is more than, was originally fixed on distal femur
Dissection lockplate nail hole diameter；The distal end setting of the steel plate ontology holds section；The holding section and the steel
This body by integral forming of plate；Nail hole is arranged in the holding section.
Further, the holding section connects to form L-type structure with the steel plate ontology.
Further, the holding section nail hole is using fixation（Angle）Locking design or universal lock design；It is described
3.5 millimeters of holding section nail hole diameter.
Further, the steel plate ontology nail hole diameter is more than 4.5 millimeters（4.5 millimeters are dissected for conventional distal femur
Locking steel plate nail hole size）, and it is less than 5.5 millimeters（Prevent excessive rear influence armor plate strength）.
Beneficial effects of the present invention：The steel plate of the present invention increases in nail hole and the nail diameter used with Bolt-hole fits
Afterwards, the hold of bone tissue is dramatically increased, effectively solves the problems, such as conventional steel sheet for can not effectively be fixed when overhauling.
Description of the drawings
It, below will be to needed in the embodiment in order to more clearly illustrate the technical solution in the embodiment of the present invention
Attached drawing is simply introduced, it should be apparent that, the accompanying drawings in the following description is only some embodiments described in the present invention, for
For those of ordinary skill in the art, without creative efforts, other are can also be obtained according to these attached drawings
Attached drawing.
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is 2 Plate break schematic diagram of embodiment
Fig. 3 is another schematic diagram of 2 Plate break of embodiment.
Specific implementation mode
Technical scheme of the present invention will be clearly and completely described by specific implementation mode below.
Steel plate is overhauled in the distal femur dissection locking of the present invention, and steel plate, including steel plate sheet are overhauled in distal femur dissection locking
Body 1；Nail hole 2 is provided on steel plate ontology；The diameter of the nail hole 2 is more than the dissection lockplate for being originally fixed on distal femur
Nail hole diameter；The distal end setting of the steel plate ontology 1 holds section 3；The holding section and 1 one of steel plate ontology
Molding；Section is held to connect to form L-type structure with the steel plate ontology;Nail hole 2 is arranged in the holding section.It is followed closely on steel plate ontology 1
Bore dia is more than 4.5mm（4.5 millimeters are dissected locking steel plate nail hole size for conventional distal femur）, and it is less than 5.5mm, hold section
A diameter of 3.5mm of nail hole（Prevent excessive rear influence armor plate strength）.It is fixed（Angle）Locking design or universal lock design；
3.5 millimeters of the holding section nail hole diameter.
Embodiment 2
Postoperative more than 1 year of patient femur's fracture of distal, bone nonunion, Plate break.If overhauled using same type steel plate, due to
Steel plate is dissection armor plate, and placement location is fixed, and nail hole is fixed, therefore is fixed loosely.If dry plate using the present invention, nail hole and
Nail diameter increases, and can effectively fix.The setting for holding section simultaneously increases steel plate body distal end（Steel plate ontology lower end）'s
Area further increases hold.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the design of the present invention
It is defined with range, under the premise of not departing from design concept of the present invention, ordinary engineering and technical personnel is to this hair in this field
The all variations and modifications that bright technical solution is made should all fall into protection scope of the present invention, claimed skill of the invention
Art content is all documented in technology claim.
