According to the lock plate, the wings and the concave portions are arranged, so comminuted bone organizations between the upper humerus condyles can be better protected, reseting and positioning templates can be provided for the comminuted bone organizations, and the bone organizations are facilitated to heal and are prevented from deforming in a healing process.
Description
Technical field
The present invention relates to medical device technical field, be specifically related to a kind of blade plate for humeral fracture.
Background technology
Between condyle of humerus epicondyle, comminuted fracture means the fracture in distal humerus between ectocondyle and above it, belongs to fracture in elbow joint, AO typing C type.Because this kind of fracture and injury is serious, easily cause the nerve injury of ancon important blood vessels, and replacement and fixation is difficult, when dealing with improperly, easily causes Volkmann ischemic contracture or Cubitus varus deformity.
Open reduction and Kirschner wire fixation from the manual reduction clamping plate extenal fixation of China's medical science to modern Western medicine, the Therapeutic Method of this kind of fracture is updated or improved, decrease the incidence rate of the severe deformities such as the serious Volkmann ischemic contracture of harm, but still constantly there is Cubitus varus deformity, incidence rate is still higher.
In addition, comminuted fracture between serious condyle of humerus epicondyle, the degree of cracked separation of fracturing makes it to reset, and then cannot reach satisfied elbow joint function and recover.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of lockplate being specifically designed to humerus, and this lockplate can realize damaged bony tissues better and be resetted, and avoids deformity to occur.
For solving the problems of the technologies described above, the invention provides following technical scheme:
For a lockplate for comminuted fracture between condyle of humerus epicondyle, two flaps that described lockplate comprises main body, is connected with main body, described main body and flap are Y type, and two flap ends respectively arrange a recess.The present invention is by arranging flap and recess; can protect better between condyle of humerus epicondyle and pulverize osseous tissue; and provide resets, locating template for these osseous tissues pulverized, and then the healing accelerating osseous tissue also can avoid osseous tissue in agglutination, produce deformity.
In order to make lockplate physically can coordinate better with humerus epicondyle, described flap is circumferentially distortion in the longitudinal direction, and its distortion angle is 80 to 110 degree, is preferably 90 degree.Distortion of the present invention is a kind of distortion of gradual change type, makes flap more adapt to humerus form, reaches effect of better fitting.
Conveniently flap distortion, and the obstruction of having a mind to avoid other body tissues, the angle between described two flaps is 30 to 60 degree, is preferably 45 degree.If two flap angles are excessive, then the degreeof tortuosity of flap can strengthen, and is unfavorable for the processing of flap and the use of lockplate, if the angle between flap is too small, then likely can hinders the growth of other body tissues, cause secondary injury.
Conveniently lockplate is fixing, and described main body and flap are provided with lock hole, and lock hole diameter is 3-3.5 millimeter.
Pulverize tissue to fix humerus epicondyle better, described recess is provided with Kirschner wire fixation hole.On the basis of pulverizing osseous tissue reset location, make it closely be fixed together by Kirschner wire, promote the healing of pulverizing osseous tissue.
In order to strengthen the stability of lockplate, simultaneously, also in order to adapt to the fracture produced below humerus epicondyle, described main body is arranged with the restraint zone that can slide along main body, pass through restraint zone, can strengthen further fixing to the fracture produced below humerus epicondyle, restraint zone can slide along main body, makes restraint zone that suitable position can be selected flexibly to use motility to strengthen it.
Concrete, the tape that described restraint zone comprises the collar and is connected with the collar, described tape is provided with lock hole.
Further, in order to prevent restraint zone from rotating in main body, described main body is provided with guide runner, and it is protruding that described collar inwall is provided with the slide guide corresponding with guide runner.
The present invention is by arranging flap and recess; flap and recess are fitted more and protect between condyle of humerus epicondyle to pulverize osseous tissue; the osseous tissue pulverized for these provides reset, locating template; reduce operating difficulty; accelerate the healing of osseous tissue and can avoid osseous tissue in agglutination, produce deformity, there is significant technique effect.

Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
embodiment 1
As shown in Figure 1 and Figure 2; the present invention relates to a kind of anatomical form lockplate for comminuted fracture between condyle of humerus epicondyle; comprise main body 1, first flap 2, second flap 3; described first flap 2 is connected with main body 1 one end respectively with the second flap 3; make main body and the first flap 2 and the second flap 3 in y-type structure; the end of the first flap 2 is provided with the first recess 21; second flap 3 is provided with the second recess 31; first recess 21 and the second recess 31 are used for wrapping up condyle of humerus epicondyle and pulverize osseous tissue, play position reset and defencive function.In order to strengthen the parcel amplitude of the first recess 21 and the second recess 31, the area of the first recess 21 and the second recess 31 can be greater than the width of the first flap 2 and the second flap 3.
Described main body 1, first flap 1 and the second flap 3 are bar shaped thin skin shape, and be made by titanium alloy, first flap 1 and the circumferentially distortion in the longitudinal direction of the second flap 3, its distortion angle is 80 to 110 degree, be preferably 90 degree, the distortion of the first flap 1 and the second flap 3 makes the first recess 21 and the second recess 31 mutual correspondence on opening direction be conducive to carrying out replacement and fixation to the humerus of comminuted fracture, and discrete broken bone is housed inside in recess.
Conveniently flap distortion, and the obstruction of having a mind to avoid other body tissues, the angle between described first flap 1 and the second flap 3 is set as that 30 to 60 spend, and is preferably 45 degree.
