Abstract
The invention discloses an engagement device for preventing bone fusion of a fibula truncation part. The engagement device comprises a first engagement part, a second engagement part and an elastic part, wherein the first engagement part is used for engaging a first truncation end of a truncated fibula positioned at the outer side of a shin bone; the second engagement part is used for engaging a second truncation end of the fibula; the elastic part is engaged between the first and second engagement parts, so that the elastic part can be subjected to elastic deformation due to the acting force between the first and second engagement parts; and if the engagement device is engaged at two ends of the fibula truncation part, rigid re-fusion of the truncated fibula can be effectively prevented so as to remove the supporting force at the outer side of the shin bone of a patient, so that a shin bone platform can be settled uniformly.
Description
Technical field
The invention relates to that a kind of bone that prevents of fibula truncated position merges connecting device, espespecially a kind of being applied to is connected fibula two ends through blocking, and can with external force deformation, be that rigidity merges once again effectively to prevent the fibula be truncated, the bracing force of subduction to lateral of tibia, and pin down the connecting device by blocking fibula.
Background technology
Pathologic changes of knee joint, great majority are because wound, degeneration or osteoporosis etc. reason caused; At present for treatment pathologic changes of knee joint, mostly number adopts the method changing artificial joint, remove patient's focus, but owing to changing artificial joint operation, the most bone of patient must be excised, sufferer must cut larger wound, makes this type of operation have larger risk and restore slower shortcoming.
Recent medical circles, for the inner side pathologic changes of knee joint that osteoporosis causes, propose " knee joint differential settlement " theoretical, this theory is pointed out, when the osteoporosis of human tibia or after degenerating, can sedimentation phenomenon be produced, but due to the outside of human tibia, supported by fibula, therefore tibial plateau can uneven sedimentation, makes the gravity that human body bears, and can offset towards tibial medial, thus pathological changes inside the knee joint caused, causes patient's gonalgia, discomfort.According to this theory, for the settling mode of this type of pathological changes, the fibula being positioned at lateral of tibia is bestowed block operation, namely the support of lateral of tibia is removed, make tibial plateau can obtain uniform sedimentation, and making tibial medial release of pressure, thus sufferer can obtain solution and delay, remove because knee joint that this type of focus produces is ached and sense of discomfort.
In right said method, after the fibula of patient blocks, there is no suitable interface components can be limited the fibula after blocking, be connected; Connect according to the known rigid plate being widely used in orthopaedics, the fibula making to be truncated is merged in rigidity again once again, and loses the meaning of blocking fibula; Edge this, in the recuperation of patient after blocking fibula, fibula in the lower limb of patient, by muscle traction and swing, displacement, or appoint a fibula arbitrarily grow in the osseous tissue of truncated end, not restricted; Also because of like this, patient also cannot obtain stable, good expection restoration result, increases the risk of operative failure on foot.
In addition, clinically, there is some patients after for many years, due to the fibula place of being truncated comparatively convergence, and effectively do not separated, because settlement action makes fibula two truncated end of separation originally, contact again, cause fibula to produce in truncated position and merge, again support force is produced to lateral of tibia, make again the uneven sedimentation of tibia, and patient's tibial medial ache focus is recurred, cause Endodontic failure.
In view of this inventor, is add to give research, and the bone that prevents disclosing illustrated fibula truncated position merges connecting device.
Summary of the invention
