Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
The advantage of the carpal joint fixture with spring of the present utility model is: can make carpal joint resistant activity in limited range of activity, when ensureing that carpal joint obtains fully taking exercise, avoids secondary injury; Can also range of activity be regulated, enable doctor or patient oneself regulate range of activity easily according to recovery extent.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of carpal joint fixture with spring, comprises palm connecting band 1, arm connecting portion 2, adjusting portion 3, front rod 4 and a rear connecting rod 5;
As shown in Figure 4, this palm connecting band 1 is made up of flexible material, its top is provided with a plate 11; This palm connecting band 1 is for being connected with the palm of patient;
As shown in Figure 5, this arm connecting portion 2 is the platy structure of arc for cross section, is provided with two pairs of connecting holes 22, as shown in Figure 2 and Figure 3, this arm connecting band 21 is connected with this connecting hole 22, and as shown in Figure 5, the top of arm connecting portion 2 is also provided with a chute 23; This arm connecting band 21 is for being fixed on the arm of patient by this arm connecting portion 2;
As shown in Figure 6, this adjusting portion 3 comprises a connection strap 31, a pair first engaging lugs 32, a pair second engaging lugs 33 are connected annulus 34 with one;
As shown in Figure 6, the inner side of this connection annulus 34 has been evenly arranged four springs 341, and this spring 341 is along the radial arrangement of this connection annulus 34;
This connection strap 31 is slidably connected with this chute 23; The front and back position of this adjusting portion 3 can be regulated easily, facilitate the patient of different arm length to use, the palm of patient also can be facilitated up and down;
As shown in Fig. 7, Fig. 2, Fig. 3, this front rod 4 is " L " shape structure, its front end and this connecting plate 11 ball-joint, middle part and this first engaging lug 32 is hinged, the front end ball-joint of rear end and this rear connecting rod 5;
As shown in Fig. 8, Fig. 2, Fig. 3, the middle part of this rear connecting rod 5 is hinged with this second engaging lug 33, rear end is provided with four and is connected projection 51, and these four connect projection 51 and are connected with this spring 341 respectively.
When palm stretches value, the length of these four springs 341 is equal, and the tail end of this rear connecting rod 5 is positioned at the center of this connection annulus 34, the tail end stress balance of rear connecting rod 5; When the palm of patient and forearm are certain angle, this rear connecting rod 5 off-center position can be driven by this front rod 4 and rear connecting rod 5, thus make its tail end by force unbalance, the palm of patient can be made further to experience certain resistance, avoid the moving speed of palm very fast, thus secondary can be avoided to fracture.
As shown in Figure 6, the surrounding of this connection annulus 34 has been evenly arranged four adjusting bolts 342, this adjusting bolt 342 along this connection annulus 34 radial arrangement and be connected annulus 34 with this and be threaded; This spring 341 is connected with this adjusting bolt 342.At the initial stage that carpal joint recovers, can screw this adjusting bolt 342, compress this spring 341, make carpal range of activity less, movable resistance is larger; In the later stage that carpal joint recovers, can unclamp this adjusting bolt 342, the length of this spring 341 that lengthens, make carpal range of activity comparatively large, movable resistance is less; The activity of different directions can also be regulated, time as larger in carpal joint movable scope upwards, the amplitude adjusting bolt 342 of upside can unclamped is larger, and when the downward movable scope of carpal joint is larger, the amplitude adjusting bolt 342 of downside can unclamped is larger; This adjustable structure meets carpal recovery rule more, is thus more conducive to carpal exercise and recovery, can also avoid secondary injury; Regulative mode is simple, regulates the operation of this adjusting bolt 342 can have been come by the doctor in charge of patient, also can have been come by patient.
As shown in Figure 6, the inner side of this first engaging lug 32 is provided with one first ball recess 321; The inner side of this second engaging lug 33 is provided with one second ball recess 331;
As shown in Figure 7, the middle part of this front rod 4 is provided with one first spherical protuberances 41;
As shown in Figure 8, the middle part of this rear connecting rod 5 is provided with one second spherical protuberances 52;
As shown in Figure 6, the spacing between two the first engaging lugs 32 is less than the diameter of this first spherical protuberances 41; This first spherical protuberances 41 is arranged in this first ball recess 321;
As shown in Figure 6, the spacing between two the second engaging lugs 33 is less than the diameter of this second spherical protuberances 52; This second spherical protuberances 52 is arranged in this second ball recess 331.
This structure both can make carpal joint horizontal anomalous movement, and this front rod 4 and this rear connecting rod 5 also can be made to dismantle, thus was convenient to patient and wears this carpal joint fixture with spring.
Below be only the mentality of designing of some embodiments of the present utility model, when system allows, this utility model can expand to external more functional module simultaneously, thus expands its function to greatest extent.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
