Abstract
A kind of fibula truncated position prevents bone fusion connecting device from including：First convergence part, it is located at lateral of tibia and the truncated end of fibula first through blocking to be connected；And second convergence part, to be connected the second truncated end of the fibula；And an elastic portion, it is connected between first and second convergence part, makes the elastic portion can be because of the active force between first and second convergence part, and elastic deformation；The both ends of fibula truncated position are engaged on by the present invention in this way, the fibula that effectively can prevent from being truncated merges once again in rigidity, to remove the support force of patient's lateral of tibia, tibial plateau is uniformly settled.
Description
Technical field
Bone fusion connecting device is prevented the invention relates to a kind of fibula truncated position, it is espespecially a kind of to be applied to linking warp
The fibula both ends blocked, and can once again be merged, reduced to shin bone in rigidity with the fibula for effectively preventing from being truncated with outer force deformation
The bracing force in outside, and pin down by the connecting device for blocking fibula.
Background technology
Pathologic changes of knee joint, most of is caused by wound, degeneration or osteoporosis etc. reason；At present for treatment
Pathologic changes of knee joint, most of is using the method for changing joint prosthesis, releases patient's focus, but due to changing joint prosthesis hand
Art, it is necessary to cut off the most bone of patient, sufferer must cut larger wound so that such operation has larger wind
The shortcomings that danger and slower recovery.
Recent medical circles, for the inner side pathologic changes of knee joint caused by osteoporosis, propose " knee joint differential settlement " reason
By the theory is pointed out, after osteoporosis or the degeneration of human tibia, can produce sedimentation phenomenon, but outer due to human tibia
Side, supported by fibula, therefore differential settlement can occur for tibial plateau, the gravity for being born human body, can be towards tibial medial
Skew, thus lesion on the inside of caused knee joint, cause patient's gonalgia, discomfort.According to the theory, for such lesion
Settling mode, it is that will bestow to block operation positioned at the fibula of lateral of tibia, that is, removes the support of lateral of tibia, make tibial plateau can
To obtain uniform sedimentation, and make tibial medial release of pressure, sufferer thus can obtain that solution is slow, removes therefore knee produced by class focus
Joint pain and sense of discomfort.
In the right above method, after the fibula of patient blocks, the fibula after blocking can be given by having no appropriate interface components
To limit, be connected；Connected according to the known rigid plate for being widely used in orthopaedics, by the fibula for making to be truncated again once again in rigidity fusion
Together, the meaning for blocking fibula is lost；Edge this, patient is in the recuperation after blocking fibula, and fibula is in the leg of patient
It is interior, drawn and swung, displacement by muscle, or appoint fibula arbitrarily to be grown in the bone tissue of truncated end, it is not restricted；Also because such as
This, patient simultaneously can not obtain stabilization, good expection restoration result, increase the risk of operative failure on foot.
In addition, clinically, there are some patientss after for many years, due to the fibula place of being truncated more convergence, and do not have
Effectively separated, because settlement action makes the truncated end of fibula two of separation originally, contact again, cause fibula in truncated position
Fusion is produced, support force is produced to lateral of tibia again, makes shin bone that differential settlement occur again, and makes patient's tibial medial ache
Focus recurs, and causes Endodontic failure.
In view of this inventor, is plus gives research, that discloses fibula truncated position shown in the present invention prevents bone fusion
Connecting device.
The content of the invention
What the purpose of the present invention aimed to provide a kind of fibula truncated position prevents bone fusion connecting device, is to include：One first
