Inboard platform arc chain riveting fixing device of shin bone, behind the thighbone of knee joint or shin bone fracture piece anatomic reduction, through the cover with fixing device on the thighbone or shin bone of knee joint, then implant set screw at fixing device's near -end screw hole, only need with the cooperation of screw hole one end screw up can, so reach the reliable fixed of fracture end, allow the knee joint movable in early days simultaneously.
Description
Technical field
This utility model is related to technical field of medical instruments, fixes more particularly, to a kind of medial tibial plateau arc nail
Device.
Background technology
Knee joint function disorder is bone injury most commonly seen in daily life, sending out especially with communication and building industry
Exhibition, in increase trend.Therefore, kneed femur and tibia have displacement fracture, operative reduction fix be it is necessary, it is how simpler
Single, more firmly fixing limbs are fractured, and how to reduce the impact to fracture blood supply so as to promote union of fracture to be always as far as possible
The emphasis and difficult point of orthopedist's concern.The common inside-fixture of knee joint function disorder includes steel wire cerclage, tension band wiring, note
Recall alloy bone pawl etc., steel wire and tension band wiring are fixed has broken needle, displacement and local soft tissue stimulation etc., thus causes knee joint
Pain during joint motion, and then affect function；Memorial alloy bone pawl is fixed can overcome Kirschner wire defect, but exist because model is selected
Size is not inconsistent causes the problems such as fixing unreliable and de- pawl or pawl branch into joint impact joint motion.
The content of the invention
In in order to overcome the shortcomings of background technology, the utility model discloses a kind of medial tibial plateau arc nail is fixed
Device, can be fixed well to the knee joint after fracture.
In order to realize the goal of the invention, this utility model is adopted the following technical scheme that：A kind of medial tibial plateau arc
Nail fixing device, including fixation steel plate body and Positioning screw, the fixation steel plate body is and knee joint bone surface phase
The semicircular arc structure of laminating, is provided with location hole on one end steel plate of the fixation steel plate body, arrange on other end steel plate
There is screwed hole, the location hole is corresponded with screwed hole, and is connected by Positioning screw between the corresponding hole of each two.
For further improved technology scheme, screwed hole described in the utility model is internally provided with screw thread.
For further improved technology scheme, screwed hole described in the utility model and location hole are distinguished in fixation steel plate body
It is horizontally arranged with several.
For further improved technology scheme, Positioning screw described in the utility model includes head of screw and screw body, spiral shell
One end of nail body is fixed with head of screw, and the other end is screw tip；Head of screw one end on the screw body is additionally provided with spiral shell
The screw thread that stricture of vagina is engaged.
For further improved technology scheme, the two ends of fixation steel plate body described in the utility model are additionally provided with cuved nail
Hook.
For further improved technology scheme, the material of fixing device described in the utility model is titanium alloy.
As a result of above-mentioned technical proposal, this utility model has the advantages that：Tibia described in the utility model
Inner side platform arc-like rows nail fixing device, after kneed femur or tibial bone folded block anatomical reduction, by by fixing device
Be enclosed within kneed femur or tibia, be then implanted into Positioning screw in the proximal screw hole of fixing device, only need to be by screw thread
Hole one end fits are tightened, and the reliability for so reaching fracture end is fixed, while allowing knee joint early ambulant.
Further, since the two ends of this utility model fixation steel plate body are additionally provided with cuved nail hook, for further helping
Help fixed tibial inner side platform arc-like rows nail fixing device.Meet tension band fixation principle, it is fixed reliable；Do not invade and quadriceps femoris
Tendon, it is allowed to knee joint early ambulant.This utility model is practical, simple to operate, fixed reliable.
