Abstract
The utility model discloses a proximal anterior rib joint fixator, which is a device for fixing a proximal anterior rib joint. The proximal anterior rib joint fixator comprises a section of flat main body connecting plate or a section of main body connecting plate with curvature, wherein the two side edges of the main body connecting plate are respectively provided with at least one pair of encircling arms vertical to the plane of the main body connecting plate. According to the proximal anterior rib joint fixator, anti-slid fixing teeth are arranged on the two sides of the encircling arms respectively, and the fixing teeth can be used for preventing the fixator from moving after the fixator is fixed.
Description
Technical field
This utility model relates to a kind of fixed apparatus of orthopaedics, and this utility model is a kind of for the holder that the nearly joint of preceding rib is fixed exactly.Include in this utility model one section straight or have a main body connecting plate of curvature.
Background technology
Traditional rib blade plate is one straight or have the main body connecting plate of curvature, and it can solve general fracture of rib problem, but some cases relates to the cartilaginous tissue fracture of breastbone and rib junction.Row needs nail is implanted in rib spongy bone place fixedly the time when adopting traditional blade plate for this damage, not only to the skeleton infringement greatly and also fixed effect unreliable.If fracture line from sternal margin very close to, even if blade plate is placed successfully, it is stressed also also unreliable.
Summary of the invention
This utility model provides a kind of device that is used for fixing preceding rib fracture near the joint that overcomes the prior art deficiency.
The nearly arthrodesis device of rib before of the present utility model, comprise one section straight or have a main body connecting plate of curvature, be respectively arranged with at least one pair of perpendicular to the arm of encircling on main body connecting plate plane at the dual-side of main body connecting plate.
Before of the present utility model in the nearly arthrodesis device of rib, can be respectively arranged with anti-skidding fixed teeth encircling the arm both sides.These fixed teeth can overcome device and be moved after fixing.
Preferably arrange three pairs in the nearly arthrodesis device of rib before this utility model and encircle arm, best fixed effect can be arranged like this.
The nearly arthrodesis device of rib before of the present utility model is provided with the drag hook that is used for connecting breastbone perpendicular to the main body connecting plate at the main body connecting plate along an end of its length.Adopt this drag hook constructional device that has, can effectively the position of rib and breastbone be fixed.Better structure is to be provided with anti-skidding fixed teeth in the side of the drag hook that connects breastbone in the device.
The nearly arthrodesis device of rib adopts the marmem manufacturing that best result of use is arranged before of the present utility model.
Encircle arm owing to being provided with in the device of the present utility model, in device uses, encircle arm and be fixed on the rib bone by the mode of encircling, add the effect of encircling the anti-slop serrations of the left and right sides on the arm, the main body of fixture that can be more stable has limited moving of its left and right directions.In addition, the sweep that is arranged at the breastbone drag hook of apparatus main body connecting plate one end can insert in advance and bore in the good hole at breastbone, can play the effect that connects rib and breastbone.And set drag hook anti-slop serrations can effectively prevent getting loose of breastbone drag hook again on the breastbone drag hook.Therefore device of the present utility model than the fixture of prior art have better, more reliable fixed effect.
From this utility model apparatus structure and use as seen, device need not to hole at rib when inserting, and also need not to fix with the steel wire bondage, so can make its operation process simplification in addition.Particularly when this utility model adopts shape memory alloy material to make, prepare corresponding fixture by patient's Signs during fabrication, to encircle arm in when operation after by the brine-cooled device opens, after device is placed in the rib relevant position, effect lower device at body temperature can recover original shape, with firm the fixing of fracture, the drag hook that connects breastbone simultaneously also can produce lasting active force, with breastbone and intercostal position together, the operation of its operation will be simplified greatly, and all these effects are that prior art does not have fully.
Description of drawings
Accompanying drawing 1 is the front view of most preferred embodiment of the present utility model, accompanying drawing 2 is the profile for A-A position in the accompanying drawing 1, accompanying drawing 3 is the vertical view of accompanying drawing 1, accompanying drawing 4 is the embodiment sketch map that have main body connecting plate plain bending of this utility model according to the characteristics preparation of rib structure, accompanying drawing 5 be this utility model under user mode for the fixing sketch map of breastbone and rib.Among the figure: 1 is anti-slop serrations, and 2 for encircling arm, and 3 is the main body connecting plate, and 4 is the breastbone drag hook, and 5 for being located at the anti-skidding fixed teeth on the breastbone drag hook.
The specific embodiment
This utility model is said below in conjunction with the accompanying drawing principal solution.
Referring to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, the optimum structure of device of the present utility model is to be made of a main body connecting plate 3 and the breastbone drag hook 4 of encircling arm 2, be positioned at main body connecting plate 3 one ends and be approximately perpendicular to the main body connecting plate that is arranged at main body connecting plate 3 both sides and is approximately perpendicular to the main body connecting plate.Main body connecting plate 3 wherein is roughly straight plane.Perhaps be the curved surface consistent with patient's rib curvature, be provided with non-slip hook 1 in the side that encircles arm 2, also be provided with non-slip hook in the side of breastbone drag hook 4.For being applicable to different patients' needs, or be applicable to the rib that longitudinally also has curved shape, main body connecting plate 3 also can vertically have the bending that adapts along it, shown in accompanying drawing 4.
Whole device of the present utility model can adopt the marmem manufacturing, the niti-shaped memorial alloy preparation preferably of the most handy biocompatibility.
In using, operation earlier device cooling of the present utility model is gone below the critical temperature, to encircle arm 2 then opens, and breastbone drag hook 4 is pulled outwardly makes its suitable distortion, again device is positioned over the rib place of operative site, and breastbone drag hook 4 is placed in advance in the hole that breastbone gets out.Then can the suture operation window.Under the effect of patient temperature, device of the present utility model produces person's movements and expression, and it is encircled arm 2 and encircles on rib, makes breastbone drag hook 4 tightly act on breastbone and rib place simultaneously, makes and realizes firm fixing between rib and breastbone.
