Abstract
The utility model relates to a multifunctional multiposition fracture reduction fixed unit used for fixing the fracture between the lower end of the femur and the upper bone of the condyle, which is composed of a fixing support frame, a telescoping mechanism, an elevate mechanism, snake head needles, etc., wherein, the telescoping mechanism is vertically connected with the elevate mechanism, the elevate mechanism is connected with the fixing support frame, and the snake head needles are arranged on one end of the telescoping mechanism and are approximately perpendicular to the telescoping mechanism. The utility model has functions of opening, lifting and pressing, squeezing each other, and poking. The utility model has the advantages that various fractures of the lower end of femur and the lower bone of the condyle can be cured without operation, patients feel less pain, the reduction fixation is reliable, early function exercise can be conducted, the excellence rate of cure reaches 87.5%, and the structure is simple. The utility model is easily manufactured.
Description
This utility model belongs to the orthopedics department external fixation device, a kind of multi-functional multi-faceted fracture reduction fixator.
Existing treatment extremity long bone shaft fracture has two kinds of conservative treatment and operative therapys as the method for treatment distal part of femur and supracondylar fracture.Conservative treatment adds plaster fixation or small splints fixation based on the bone traction, this therapy patient's long-term bed, the shortage activity is taken exercise, not only cause arthrogryposis, and, older person easily produces complication such as decubital ulcer, pulmonary and urinary system infection, according to relevant document its function satisfaction rate average out to 62,2% of reporting for work.Hands is stated therapy and is divided into marrow internal fixation and marrow external fixation two big classes, fixing steel plate or the Kirschner wire etc. of adopting respectively, and must be at the thigh upper cut, operation technique is difficulty relatively, its therapeutic effect is seen still very dissatisfied from functional rehabilitation, the wound and fixed influence, the knee joint activity that add operation will inevitably be under some influence, postoperative knee joint function satisfaction rate average out to 73.5%.
The purpose of this utility model provides a kind ofly can treat the extremity long bone shaft fracture, and heals, and functional rehabilitation is fast, the multi-functional multi-faceted fracture reduction fixator that the function satisfaction rate is high.
The purpose of this utility model is achieved in that the reduction fixture device of being made up of fixed support, telescoping mechanism, elevating mechanism, snakehead pin etc., its telescoping mechanism is connected with the elevating mechanism approximate vertical, elevating mechanism links to each other with fixed support, the snakehead pin is arranged on an end of telescoping mechanism, and roughly perpendicular with telescoping mechanism.
The utlity model has retract, carry by, to squeeze, functions such as rotation, prying and pulling, all directions are adjustable, and are simple to operate, easy to use, not otch.Patient's misery is little, and it is fixing reliable to reset, and patient's bed rest time is short, can carry out functional exercise in early days, and patient feels the comfortable this Therapeutic Method of being willing to very much.This utility model is simple in structure, and processing and manufacturing easily has good popularizing value.
Other features and advantages of the utility model can be found out by following drawings and Examples.
Fig. 1 is a kind of concrete structure sketch map that this utility model is implemented.
Among the figure, 1, fixed support; 2, bandage; 3, wing nut; 4, connecting plate; 5, lifting turn-knob, 6, clamp nut; 7, rotating shaft; 8, lifting regulating rod; 9, inserting needle turn-knob; 10, snakehead pin; 11, telescopic adjustment bar; 12, band tooth rotating mechanism; 13, sleeve pipe; 14, flexible turn-knob; 15, U-shaped card; 16, backing plate.
