Description
Technical field
This utility model relates to a kind of hands exter-nal fixer, relates to a kind of with miniature dynamic adjustments palm finger joint style deformity corrector specifically, belongs to bone-specific drug technique with the apparatus field.
Background technology
The anatomical structure of brothers is tiny, but function is meticulous.Brothers, after generation fracture with joint dislocation, easily cause the generation of the complication such as joint stiffness and traumatic arthritis.Especially for the brothers' wound with local skin soft tissue injury or blood vessel injury, processing method is improper, and the lighter can cause delayed union and the poor arterial inflow of wound surface and fracture, and severe patient can cause skin soft tissue necrosis, exposed bone, even limb necrosis, therefore deals with very thorny.Because brothers' bone is short and small tubular bone and irregular bone, muscle or tendon attachment point more, and around have tendon-film slide construction adjacent, to the function of hand and foot more after very easily produce obvious adverse effect.Numerous scholars constantly grope the treatment technology improving brothers' disease always, and constantly the more minimally-invasive treatment mode of thinking, compares Gypsum Fibrosum, clamping plate, blade plate, Kirschner wire, and external fixator has more unique advantage concerning brothers' surgery.
Exter-nal fixer refers to fixing osteoarticular special device, the earliest for fixing fracture.Extenal fixation refers to be worn put steel nail at the proximal part of fracture and distal end percutaneous, then is tied each other by exposed nail end outside skin with connecting rod and steel nail fixation clamp, thus fixing a kind of Therapeutic Method of fracturing.Its fundamental mechanism is the equilibrium condition by power, is deformed and then produces active force, act on fracture face by steel nail, makes fracture end produce longitudinal pressure, thus promotes union of fracture.Its major advantage is to provide stable extenal fixation for fracture end, prevents from again destroying local blood circulation, at mechanics be that union of fracture creates advantage in biology two.Particularly efficiently solve in Open fracture treatmeT skin soft tissue condition bad and fracture needs fix between contradiction.
Malgaigne first Application exter-nal fixer in 1840, has started the history of exter-nal fixer treatment orthopaedic disease.Within 1902, Albin Lambotte first creates the external fixator that can be used for multiple limb long tubular bone.The loopful formula external fixer of former Soviet Union scientist Ilizarrov design in 1976, belongs to many plane formulas holder, is used for the treatment of osteomyelitis.Domestic Lee plays letter and have developed half-ring fixator in late 1970s, and is successfully applied to clinical, and from then on external fixator starts the attention being subject to orthopedics expert.Through the development of a century and a half, particularly nearly 30 years, deepening continuously of bone extenal fixation fundamental research, improvement and the operation of exter-nal fixer progressively improved, and constantly deepen the understanding of this technology.Exter-nal fixer is as a basic fundamental of brothers' surgery, more and more extensive in clinical application at present, and achieves good effect.
The external fixator of current brothers' surgery also also exists deficiency, is mainly manifested in product category less, function singleness, complex operation.And existing external fixator lacks for palm phalanges and articulations digitorum manus is lopsided, the external fixator of tiger's jaw cicatricial contracture and finger-joint flexion deformity.We research and develop new product just for this, provide new demand for meeting clinical position needs.
