The specific embodiment
Seeing also Fig. 1 to Fig. 4, is the selected example structure of this utility model shown in the figure.
The location structure of the knee joint fixator of present embodiment comprises:
One block mechanism 4;
One auxiliary device 1, has one first sheet material 11 and one second sheet material 12, one end of this first sheet material 11 and two symmetries protecting cover 2,3 in opposite directions connects fixing, and utilize a binding member 13 to make these second sheet material, 12 insertions be articulated in 2,3 of each protecting covers, this first and second sheet material 11,12 can be pivoted relative to each other, and be positioned the expansion of an angle with 4 controls of this block mechanism, or remove the restriction of these 4 pairs of these second sheet materials 12 of block mechanism and can rotate this second sheet material 12 arbitrarily, to be used in affected part joint constraints limb motion scope.
This block mechanism 4 comprises:
One toggle 41, this toggle 41 are slidedly arranged in the set action groove 21 of one of them protecting cover 2 of each protecting cover 2,3, and this action groove 21 is to have an elongated hole 22.
One moving part 42, it is to stretch through this elongated hole 22 and can be synchronized with the movement with this toggle 41.
One joggle piece 43, it is to connect with this moving part 42 and moves back and forth in the same way with this toggle 41, so that the opposite end bridle joint of this joggle piece 43 and this second sheet material 12, and control the expansion that each sheet material 11,12 is positioned an angle.In the present embodiment, this joggle piece 43 is at a relative end of this second sheet material 12, has a dog point 431 that is continuous dentation, and this second sheet material 12 is provided with a resistance limit 122 that is continuous dentation in the opposite end outer rim.Wherein this second sheet material 12 is the axis part 121 that an annular is worn pivot for this binding member 13 at an end of relative this joggle piece 43, and this resistance limit 122 is the outer rims that are arranged at this axis part 121.
Two rotating disks of assembling mutually 24,34 be to be arranged on the one protecting cover 2 with coaxial, and each rotating disk 24,34 are respectively equipped with a press button 25,35.
Two locating parts 26,36 are the depressed parts that are installed in each protecting cover 2,3 respectively.Each locating part 26,36 is respectively equipped with second ring teeth groove 262,362, and each rotating disk 24,34 cunning is respectively established and is positioned in the teeth groove of each ring slot 262,362, but to adjust the amplitude range of 12 pivots pendulum of this first sheet material 11 and this second sheet material.
Two are connected part 27,37, are to be installed in respectively between each locating part 26,36 and first sheet material, 11 1 ends, and joggle piece 43 is to be located at respectively to be connected between the part 27,37.
Each locating part 26,36 and respectively be connected part 27,37 and respectively be provided with an elongated hole 261,361,271,371 in elongated hole 22 positions to action groove 21 that should protecting cover 2 reaches and respectively is connected the elongated hole 271,371 of part 27,37 and is incorporated into this joggle piece 43 for the stretched through elongated hole 261,361 of elongated hole 22, each locating part 26,36 of this action groove 21 of this moving part 42.
When the pivot of institute's predetermined amplitude range of adjusting 12 of this first sheet material 11 and this second sheet materials is put, it is earlier to press button 25,35 radially exert pressure, can make each rotating disk 24,34 are not subjected to each locating part 26,36 ring slot 262,362 alignment restrictions, and in each locating part 26,36 ring slot 262, rotate arbitrarily in 362, then, when each rotating disk 24,34 when going to the precalculated position, decontrol press button 25 again, 35, so that each rotating disk 24,34 are subjected to each locating part 26,36 ring slot 262, the predetermined teeth groove of 362 one is located, and allows this first sheet material 11 and 12 of this second sheet materials can make the pivot pendulum of predetermined amplitude.
Moreover, when stir this toggle 41 make this moving part 42 along this elongated hole 22 towards away from this binding member 13 directions action the time, this moving part 42 is these joggle piece 43 displacements of interlock and away from this binding member 13, and the resistance limit 122 of the dog point 431 of this joggle piece 43 and these second sheet material, 12 axis parts 121 is disengaged position.At this moment, this second sheet material 12 is the center with this binding member 13, and at random rotates in these two rotating disks, 24,34 angular ranges that limited and in this two locating part 26,36.
Otherwise, if stir again this toggle 41 make this moving part 42 along this elongated hole 22 when these binding member 13 directions are moved, these joggle piece 43 displacements of these moving part 42 interlocks and towards these binding member 13 directions, and the dog point 431 of this joggle piece 43 is engagement with the resistance limit 122 of these second sheet material, 12 axis parts 121, and then this second sheet material 12 is positioned and can not at random rotates.
During use, as Fig. 5 and shown in Figure 6, this auxiliary device 1 is with this flexible position of rotating disk 34 corresponding limbs, and do not influencing under the preceding topic of limbs bending, patient's fracture site is seized on both sides by the arms by each sheet material 11,12 respectively, and utilize rope, band or binder to be fixed.So, can be fixed on the expansion pattern of a certain angle by these block mechanism 4 each sheet materials 11,12 of control, or remove the restriction of this block mechanism 4, this second sheet material 12 can at random be rotated in these two rotating disks, 24,34 selected angular ranges.
By the explanation of the foregoing description as can be known, advantage of the present utility model is, each sheet material is to form a rotary part with a relative end, and insert between two corresponding protecting covers, a sheet material wherein has an axis part that is the resistance limit of continuous dentation, and utilize one of block mechanism to have the joggle piece of the dog point that is continuous dentation, and can carry out the bridle joint relation to the axis part, to do the selection of disengaged position or engagement, change unfolded movable amplitude size for dialling mutually between each sheet material of location, promptly utilize block mechanism toggle stir switching, can not move and make each sheet material at random rotate or to present set kenel.
The above, it only is preferred embodiment of the present utility model, be not that this utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
In sum, this utility model is on structural design, use practicality and cost benefit, it is required to meet industry development fully, and the structure that is disclosed also is to have unprecedented innovation structure, have novelty, creativeness, practicality, the regulation that meets relevant novel patent requirement is so mention application in accordance with the law.
