Abstract
The utility model relates to a fracture external fixing supporting frame which belongs to the technical field of surgery medical instruments. The utility model solves the technical problem of providing a fracture external fixing supporting frame which is good for stimulating the growth of calluses and the shaping of skeleton. The utility model has the scheme that the fracture external fixing supporting frame comprises a fixing needle and a frame body, wherein, the frame body is formed by the movable fit and the inserted connection of two semi-frame bodies, and the inserted part is provided with a connecting spacer pin which is fixed with one of the two semi-frame bodies and is movably matched with a sliding groove of the other semi-frame body. After using the utility model to carry out fracture fixation, stress force stimulation can make a distance between the fixed points of two sections of broken bones synchronously reduced, and in this way, the utility model can eliminate stress force occlusion and promote fracture concrescence.
Description
Technical field
This utility model relates to a kind of external fixation of fracture support, belongs to the surgical medical equipment technical field.
Background technology
Medical research proves that fracture site is fine motion controlledly, comprises vertically and do not surpass the lateral movement of the toleration of repair tissue, can stimulate growth of spur, increases its strength and stiffness.But use traditional rigid body exterior fixation bracket to carry out fracture fixation, the mutual alignment between two sections knochenbruch of postoperative is immobilized, like this, fracture site is subjected to stress shielding, can not get stress stimulation, influences union of fracture.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of external fixation of fracture support, this fixed support is in fracture healing process, and along with functional section refining stress stimulation, muscle contraction etc., fine motion appears in the distance between two broken ends of fractured bone, help stimulating growth of spur, skeleton is moulding.
It is as follows to solve the problems of the technologies described above the technical scheme that is adopted:
A kind of external fixation of fracture support, it comprises locking pin and support body, said support body is pegged graft movingly by two semi-frame bodies and is constituted, plugging position is provided with the connection spacer pin, connect spacer pin and one of them semi-frame body and fix, with the chute of another semi-frame body for movingly.
Above-mentioned external fixation of fracture support is provided with spring washer between the spliced eye bottom of a said semi-frame body and another semi-frame body grafting axle head, and the plugging position of two semi-frame bodies is provided with lock-screw.
Above-mentioned external fixation of fracture support, said connection spacer pin are two connection spacer pins parallel and that install perpendicular to the support axis.
Above-mentioned external fixation of fracture support, said connection spacer pin are two connection spacer pins that are three-dimensional plumbness and all install perpendicular to the support axis.
External fixation of fracture support provided by the utility model, be traditional rigid body exterior fixation bracket to be designed to two halfbody supports grafting form, two halfbody supports allow the shifting amount of 1-3mm vertically each other, therefore, after use this utility model carries out fracture fixation, in fracture healing process, stress stimulation can make two sections spacings between the knochenbruch fixing point dwindle synchronously, like this, can eliminate stress and block, promote union of fracture.In addition, setting up of lock-screw and spring washer can be in fracture healing process, according to different stages biology, unclamp or lock lock-screw, to realize controlledly fine motion of fracture site, to reach the stimulation growth of spur, favourable skeleton is moulding, increases the purpose of its strength and stiffness.This external fixation of fracture support is identical with traditional exterior fixation bracket purposes.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment:
Referring to accompanying drawing, this external fixation of fracture support comprises that locking pin, support body are fixedly connected for screw thread between the two, said support body is pegged graft movingly by two semi-frame bodies 1,4 and is formed, plugging position is provided with and connects spacer pin 3, it is fixing with one of them semi-frame body 4 to connect spacer pin 3, with the chute 2 of another semi-frame body 1 for movingly.Wherein, Fig. 1, connection spacer pin 3 shown in Figure 2 are two connection spacer pins parallel and that install perpendicular to the support axis.Fig. 3, connection spacer pin 3 shown in Figure 4 are two connection spacer pins that are three-dimensional plumbness and all install perpendicular to the support axis.The plugging position of Fig. 5, two semi-frame bodies 1,4 shown in Figure 6 is provided with lock-screw 5, and is provided with spring washer 6 between the grafting axle head of the spliced eye bottom of one of them semi-frame body 4 and another semi-frame body 1,6 damping, bufferings of this packing ring, oligodynamics.
This utility model is early stage after operation, can utilize lock-screw 5 restriction fine motions, keeps the reliable and stable of fracture end, is beneficial to the healing of fracture.
Middle and advanced stage is opened lock-screw 5 after surgery, makes external fixer become dynamic regime by the static(al) state, realizes the elasticity fine motion, helps symphysis and moulding and minimizing stress shielding.
Elasticity fine motion of the present utility model has guaranteed that it is gentle pushing but not the bump of violence nature that fracture end is accepted the character of stress.In the functional exercise process, the stress that is lower than elastic modelling quantity does not produce fine motion, and keeps stable.The stress that is higher than elastic modelling quantity is carried and is formed gentle periodicity at fracture end by exterior fixation bracket and formed optimal stimulation by compressive stress, promotes knitting and moulding.
