The traditional fixing devices for restoration have the defect that the rotating malposition of fracture positions can not be adjusted. The utility model comprises a main frame, a steering device and a fixing device of a tightly fixed shaft, wherein, the main frame is in the shape of a fork, and the steering device is formed by the mutually vertical connection of two sectors. The two sectors of the steering device are clamped by two fork sheets of the main frame respectively. A regulating threaded rod is screwed in a fork handle of the main frame, and a regulating outer sleeve is sheathed on the fork handle. The fixing device of a tightly fixed shaft is fixed on the regulating outer sleeve. The fixing device for the restoration of fracture of the utility model not only can regulate the overlapping and separating degree of fracture positions, but also can regulate the angulation deformity and the rotating malposition of the fracture positions.

Description

多功能骨折复位固定器 Multifunctional fracture fixator

本实用新型涉及一种多功能骨折复位固定器,一种骨折病人的康复装置。 The present invention relates to a multifunctional fixation device fractures A fracture patients rehabilitation device.

骨折复位固定器是骨折病人康复所必需的治疗装置,一般的骨折复位固定器包括主架、转向器、调节外套、调节螺杆、紧定轴等构成,但由于传统产品的调节外套与主架之间通过键槽和键销定向,相互间只能作长短距离的调节,不可旋转,故不能调整骨折部位的旋转错位,另一方面,传统固定器的转向器采用的是球头螺杆来调节骨折的内外和前后成角,其缺点是只能作单向调节,调节角度也较小,操作难度大。 Fracture fixation fracture treatment device is necessary for rehabilitation of patients, the average fracture fixation comprising a main frame, steering, regulation jacket, adjustment screw, the shaft adapter or the like, but since the regulating jacket of the main frame of the conventional product between the key groove and the key pin oriented to each other can be adjusted length of the distance, non-rotatable, it can not adjust the rotational displacement of the fracture site, on the other hand, the conventional diverter fixture is used to adjust the ball screw shaft fractures inside and outside the front and rear angled, the drawback is only one way for adjusting the angle of adjustment is small, operation is difficult.

本实用新型的目的在于提供一种克服了上述缺点的多功能骨折复位固定器,用该固定器不仅能调节骨折部位的重叠与分离程度,还能调整骨折部位的成角畸形以及旋转错位。 The present invention aims to overcome the above disadvantages to provide a multifunction fracture fixation device, with which the holder can not only adjust the degree of separation overlaps with the fracture site, but also to adjust the angular deformity and rotational misalignment at the fracture site.

本实用新型的多功能骨折复位固定器,包括两主架、转向器和两紧定轴固定器,所述主架呈叉状,其一端有内螺孔,另一端为两片平行叉片,所述转向器由两片相互垂直连接的扇面构成,在两扇面上各有一条弧形孔槽,而所述主架的叉片分别夹住所述转向器的扇面,扇面通过定位螺钉固定到所述主架的叉片上,在所述主架的叉片上设置有穿过所述转向器扇面上的孔槽的紧定螺钉,在所述主架的内螺孔内旋入有一带有凸肩的调节螺杆,还有调节外套套在所述主架和所述调节螺杆上,并受所述调节螺杆上的凸肩的支撑,在所述调节外套上有能使调节外套与所述主架固定的固定结构,所述紧定轴固定器固定在所述调节外套上。 The present invention multifunctional fracture fixation comprising two main frame, and two steering shaft adapter holder of the main frame fork at one end thereof with a threaded hole, the other end two parallel tines, the diverter consists of two mutually perpendicular connecting the fan, one on each face of two arcuate opening groove, and said main frame for clamping the tines of the steering fan, the fan is fixed by screws to the the tines of the main frame, is provided with a slot through set screw holes on the fan diverter tines on the main frame, screwed into the threaded hole in the main frame having a protrusion shoulder adjustment screw, as well as adjustment of the main frame in the outer sleeve and the adjusting screw, and by adjusting the support shoulder on the screw, which enable the adjustment of the jacket on said main adjusting jacket fixing frame fixing structure, the adapter shaft holder secured to said regulating jacket.

以上面的描述可以看出,两主架可分别绕固定主架和转向轴的定位螺钉转动,并且由于转向器由两相互垂直的扇面构成,所以两主架的转动方向相互垂直,能在两个方向上调节骨折部位的成角畸形,另外,调节外套是套在主架上的,它可带动固定在其上的紧定轴固定器旋转,从而进行骨折部位旋转错位的调整。 As can be seen in the above description, both the main frame and the frame is rotatable about the fixed main axis of rotation of the steering screw, respectively, and since the diverter consists of two mutually perpendicular sector, the direction of rotation of two of the main frame perpendicular to each other, the two can adjusting the directions of the fracture site angular deformity, further, adjustment is set in the outer main frame, which can drive shaft adapter fixed thereon is fixed on the rotation, thereby adjusting the rotational displacement of the fracture site.
