Abstract
This utility model relates to acropathy long bone fractures locking extenal fixation steel shield, it is characterized in that shield body entirety is in round and smooth oval peltate, the bottom of this shield body is planar structure, nearly joint person carries the radian meeting skeleton structure, and shield body is domes from two ends to mid portion progressive additive, shield body is arranged lock hole and pressurization fixing hole, lock hole side is provided with pressurization fixing hole, be provided with internal thread in lock hole, the internal thread in this internal thread and lock screw matches, for fixedly locked screw.The beneficial effects of the utility model are, without the need to peeling off muscle and periosteum, union of fracture is fast, really have wound little, recover fast feature, both avoided fracture site stress and concentrated the danger causing fracture in the middle of steel shield, turn eliminated the strong stress shielding fixedly caused in steel shield two ends, postoperative can descend part walking with load, install convenient, remove simple, be easy to nursing, color is optional, meets the life idea of modern and the principle of fracture wholistic therapy.
Description
Technical field
The present utility model relates to a kind of orthopedic medical device, specifically a kind of acropathy long bone fractures locking extenal fixation steel shield.
Background technology
The operative treatment of traumatic acropathy long bone fractures mainly adopts the apparatuses such as screw, Kirschner wire, wirerope, steel plate, intramedullary pin and external fixer to carry out replacement and fixation, adopts the complication such as the easy accompanying infection of bone Internal fixation technology such as steel plate and intramedullary pin and osteomyelitis, steel plate screw fracture, fracture delayed union, bone does not connect Cranial defect, second operation taking-up; Shortcomings such as adopting the bone External technique of external fixer to have apparatus complexity, pin track infection, loosen fracture, ankylosis, impact is attractive in appearance, compliance is poor.All there is above-mentioned different defect and deficiency in internal and external fixation instrument such as the locking for the treatment of acropathy long bone fractures open reduction internal fixation steel plate and mixed external fixator etc. more advanced at present, make troubles often to clinical treatment acropathy long bone fractures, even lead to malpractice, therefore, those skilled in the art is devoted to exploitation one and more meets biomechanical principle, has both the fixed apparatus of both locking internal fixation steel plate and mixed external fixator advantage simultaneously.
Summary of the invention
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, acropathy long bone fractures is provided to lock extenal fixation steel shield, this utility model solves the technical scheme that its technical problem adopts: structure of the present utility model comprises shield body, lock hole, pressurization fixing hole, internal thread, lock screw, it is characterized in that shield body entirety is in round and smooth oval peltate, the bottom of this shield body is planar structure, nearly joint person carries the radian meeting skeleton structure, shield body from two ends to mid portion progressive additive be domes, shield body is arranged lock hole and pressurization fixing hole, lock hole side is provided with pressurization fixing hole, internal thread is provided with in lock hole, internal thread in this internal thread and lock screw matches, for fixedly locked screw.
Using method: after acropathy long bone fractures closed reduction or Limited open reduction, shield body is passed through lock screw extenal fixation in the skin surface of long bone, carry out functional exercise according to the rule of union of fracture, be interrupted according to the suitableeest rigidity principle of fracture fixation after union of fracture and take out lock screw.
The beneficial effects of the utility model are, adopt closed reduction or Limited open reduction, and without the need to peeling off muscle and periosteum, significantly improve the growth recovery of periosteum and blood fortune, union of fracture is fast, meets the traumatology department's Damage Coutrol principle; Fracture two ends only need to squeeze into several pieces of screws by steel shield and namely complete by Wicresoft fixing, really have wound little, recover fast feature, meet orthopaedics Natural Reconstruction principle; The interlocking being locked screw by screw and steel shield is fixed, and overall fixedly have angulation stability, can ensure the rigidity of fixation at initial stage, have again resiliently mounted advantage, meet the biomechanical principle of external fixation of fracture; The design mid portion of locking extenal fixation steel shield thickeies, two ends are thinning gradually, both avoid fracture site stress and concentrate the danger causing fracture in the middle of steel shield, turn eliminate the strong stress shielding fixedly caused in steel shield two ends, postoperatively can descend ground part walking with load, meet the Mechanics Principles of fracture fixation material; Along with the progressively healing of fracture, adopt the mode of being interrupted and taking out screw, the rigidity of fixation of locking extenal fixation steel shield can be regulated, meet the suitableeest rigidity principle of fracture fixation; Install convenient, remove simple, be easy to nursing, color is optional, meets the life idea of modern and the principle of fracture wholistic therapy.

Detailed description of the invention
Illustrate with reference to accompanying drawing and following concrete detailed description is done to this utility model, as shown in drawings, structure of the present utility model comprises shield body 1, lock hole 2, pressurization fixing hole 3, internal thread 4, lock screw 5, it is characterized in that shield body 1 entirety is in round and smooth oval peltate, the bottom of this shield body 1 is planar structure, nearly joint person carries the radian meeting skeleton structure, shield body 1 from two ends to mid portion progressive additive be domes, shield body 1 is arranged lock hole 2 and pressurization fixing hole 3, lock hole 2 side is provided with pressurization fixing hole 3, internal thread 4 is provided with in lock hole 2, internal thread in this internal thread and lock screw 5 matches, for fixedly locked screw 5.Using method: after acropathy long bone fractures closed reduction or Limited open reduction, shield body 1 is passed through lock screw 5 extenal fixation in the skin surface of long bone, carry out functional exercise according to the rule of union of fracture, be interrupted according to the suitableeest rigidity principle of fracture fixation after union of fracture and take out lock screw 5.
Embodiment recited above is only be described preferred implementation of the present utility model; not design of the present utility model and scope are limited; under the prerequisite not departing from this utility model design concept; the various modification that in this area, common engineers and technicians make the technical solution of the utility model and improvement; protection domain of the present utility model all should be fallen into; the technology contents of this utility model request protection, all records in detail in the claims.
