Description

Brown trailer system
Technical field
The disclosure relates to the fracture traction in clinical medicine, particularly relates to such as intertrochanteric fracture of the femur and draws the brown trailer system used.
Background technology
Along with the problem of population in the world aging is constantly aggravated, increasing middle-aged and elderly people can experience various fracture.Such as, because reasons such as osteoporosises, hip is the multiple position of the fracture of middle-aged and elderly people.Particularly, intertrochanteric fracture of the femur is more common.
Operative treatment intertrochanteric fracture of the femur often must first be drawn, and this traction sometimes can need the long time.Special orthopedic traction bed is often relatively expensive.By contrast, brown towing bracket and/or system because relatively cheap, so apply more extensive.
Fig. 1 shows the brown trailer system 100 of prior art.
As shown in Figure 1, brown trailer system 100 comprises: tetragon underframe B; The first standpipe 101, second standpipe 102, the 3rd standpipe 103 and the 4th standpipe 104 upwards holded up at four angles place of described tetragon underframe B; The first long tube 110 connected between the top of the first standpipe 101 and the top of the second standpipe 102; The second long tube 120 connected between the top of the 3rd standpipe 103 and the top of the 4th standpipe 104; The the first swan neck W1 be connected with the top of the first standpipe 101; And the second swan neck W2 to be connected with the top of the 4th standpipe 104.
In clinical practice, in order to effectively carry out preoperative traction, as shown in Figure 1, brown trailer system 100 also comprises: to be connected across between the first long tube 110 and the second long tube 120 and the first stand LJ1 of the substantially vertical band pulley upwards holded up; To be connected across between the top of the second standpipe 102 and the top of the 3rd standpipe 103 and to be roughly tilted to the second stand LJ2 of the outer band pulley holded up; To be connected between the first standpipe 101 and the 4th standpipe 104 and to be positioned at the only about half of first following transverse tube HG1 of its height; To be connected between the second standpipe 102 and the 3rd standpipe 103 and to be positioned at the only about half of second following transverse tube HG2 of its height; From the trident bracing frame SC1 holded up the centre of the first transverse tube HG1 is roughly tilted to, for adjustably supporting the first swan neck W1 and the second swan neck W2; And from the single tube bracing frame SC2 holded up the centre of the second transverse tube HG2 is roughly tilted to, for adjustably supporting the second stand LJ2.
In clinical practice, a major defect of the brown trailer system 100 of prior art is that its length and/or width etc. cannot free adjustment, such as, the distance roughly corresponding to the first long tube 110 of patient's lower-leg length and the length of the second long tube 120 and/or roughly correspond between the first swan neck W1 of patient upper leg length and the length of the second swan neck W2 and the distance between the first mutually almost parallel long tube 110 and the second long tube 120 and width and/or the first mutually almost parallel swan neck W1 and the second swan neck W2 and width cannot free adjustment, so the brown trailer system 100 of prior art cannot adapt to the different length of different patient and/or different fat or thin lower limb well.
In addition, in clinical practice, another major defect of the brown trailer system 100 of prior art is that it cannot lift the lower limb with supporting patient, the particularly foot of patient effectively, and the lower limb of patient its foot after the time that traction one section is longer often cannot be maintained a neutral position.
Moreover, in clinical practice, another major defect of the brown trailer system 100 of prior art to be mounted between the first long tube 110 and the second long tube 120 with the binder of the shank of supporting patient and/or gauze and to be arranged between the first swan neck W1 and the second swan neck W2 and to be not easy to cleaning and sterilization with the binder of the thigh of supporting patient and/or gauze, particularly by water, blood, breed bacteria and/or infected wound is very easy to when secretions and/or other liquid wets, so cannot Reusability, and change this binder every now and then and/or gauze is very consuming time often and troublesome.
Therefore, in clinical practice, wish a kind of brown trailer system of improvement, can according to the length of the different lower limb of different patient and/or fat or thin and regulate, and effectively can lifting and in long distraction procedure, remain neutral position to make it with the foot of supporting patient, cleaning and sterilization can being easy in addition and can Reusability and without the need to frequently changeing above-mentioned binder and/or gauze.
