Abstract
The utility model discloses a kind of dissection lockings of distal femur to overhaul steel plate, including steel plate ontology；Nail hole is provided on the steel plate ontology；The diameter of the nail hole is greater than the diameter for being originally fixed on the nail hole of dissection lockplate of 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 utility model dramatically increases the holding power of bone tissue after nail hole and nail diameter increase, effectively solves the problems, such as conventional steel sheet for can not effectively fix when overhauling.
Description
Technical field
The utility model belongs to medical instruments field, is related to use when bone nonunion revision procedure after a kind of Methods for Distal Femoral Fractures
Steel plate.
Background technique
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 placed in same position, locking nail
Can be placed in for the first time operation same position, this will lead to be not fixed firmly, in addition again operative failure the problem of.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of dissection lockings of distal femur to overhaul steel plate, can be significant
The firmness of Interal fixation when improving revision procedure.
In order to solve the above technical problems, the utility model adopts the following technical scheme: steel is overhauled in distal femur dissection locking
Plate, including steel plate ontology；Nail hole is provided on the steel plate ontology；The diameter of the nail hole, which is greater than, is originally fixed on femur
The diameter of the nail hole of the dissection lockplate of distal end；The distal end setting of the steel plate ontology holds section；The holding section with it is described
Steel plate this body by integral forming；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 fixed (angle) locking design or universal lock design；It is described
3.5 millimeters of diameter of holding section nail hole.
Further, greater than 4.5 millimeters, (4.5 millimeters are conventional distal femur dissection to the steel plate ontology nail hole diameter
Locking steel plate nail hole size), and less than 5.5 millimeters (preventing excessive rear influence armor plate strength).
The utility model has the beneficial effects that the steel plate of the utility model is straight in nail hole and the nail used with Bolt-hole fits
After diameter increase, the holding power of bone tissue is dramatically increased, effectively solves conventional steel sheet for can not effectively fix when overhauling
The problem of.
Detailed description of the invention
In order to more clearly illustrate the technical scheme in the embodiment of the utility model, will make below to required in embodiment
Attached drawing is simply introduced, it should be apparent that, the accompanying drawings in the following description is only some realities recorded in the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is 2 Plate break schematic diagram of embodiment
Fig. 3 is another schematic diagram of 2 Plate break of embodiment.
Specific embodiment
The technical solution of the utility model will be clearly and completely described by specific embodiment below.
Steel plate is overhauled in the distal femur dissection locking of the utility model, and steel plate, including steel are overhauled in distal femur dissection locking
Plate ontology 1；Nail hole 2 is provided on steel plate ontology；The diameter of the nail hole 2 is greater than the dissection lock for being originally fixed on distal femur
The diameter of the nail hole of fixed board；The distal end setting of the steel plate ontology 1 holds section 3；The holding section and the steel plate ontology 1
It is integrally formed；Section is held to connect to form L-type structure with the steel plate ontology;Nail hole 2 is arranged in the holding section.Steel plate ontology 1
Upper nail hole diameter is greater than 4.5mm(4.5 millimeters and dissects locking steel plate nail hole size for conventional distal femur), and it is less than 5.5mm,
The diameter for holding section nail hole is that 3.5mm(prevents excessive rear influence armor plate strength).Fixed (angle) locking design or universal lock
Design；3.5 millimeters of diameter of the holding section nail hole.
Embodiment 2
Patient femur's fracture of distal postoperative more than 1 year, bone nonunion, Plate break.If overhauled using same type steel plate,
Since steel plate is dissection armor plate, placement location is fixed, and nail hole is fixed, therefore is not fixed firmly.If using the dry of the utility model
Plate, nail hole and nail diameter increase, and can effectively fix.The setting for holding section simultaneously increases steel plate body distal end (steel plate sheet
Body lower end) area, further increase holding power.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical new to this
The conception and scope of type is defined, without departing from the design concept of the present utility model, ordinary skill skill in this field
Art personnel should all fall into the protection scope of the utility model to all variations and modifications that the technical solution of the utility model is made,
The claimed technology contents of the utility model, are all documented in technical requirements book.
