Wrist joint fixing device with spring
Technical field
The present invention relates to orthopedic medical device, a kind of wrist joint fixing device with spring is specifically referred to.
Background technology
During wrist joint surrounding fracture, carpal fixation can cause wrist joint surrounding tissue blood supply disorder, make tissue ischemia,
Anoxic and cause the useless with sexually revising of capsular ligament, ligament, periarticular tissue and bone, finally cause joint fibrous ankylosis and
Functional disorder, although limbs joint is removed after braking, periarticular Tissue Blood is for recovering, and the slight activity in joint, makes in addition
The nutrition of tissue is improved, and the retrogression of joint tissue is gradually recovered, but this recovery is extremely slow.
Chinese invention patent ZL201010151426.9 discloses a kind of wrist joint movable connecting rod fixed across wrist joint,
Wrist joint can be made to obtain the functional training of early stage, and do not influence the fixation and recovery of fracture, but used this solid across wrist joint
Fixed wrist joint movable connecting rod, the wrist joint of patient can only prevent wrist joint from obtaining sufficiently in a plane to activity
Take exercise, be unfavorable for carpal recovery;Wrist joint is in activity, without any resistance, if the wrist joint of patient recovers not
When enough good, secondary fracture is likely to result in using this wrist joint movable connecting rod fixed across wrist joint;And as wrist is closed
The recovery of section, the scope that wrist joint is capable of activity is becoming larger, and this wrist joints moving connection fixed across wrist joint
The unadjustable carpal scope of activities of bar, does not meet carpal recovery rule.

Embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
The advantage of the wrist joint fixing device with spring of the present invention is:Wrist joint can be made in limited scope of activities
Interior resistant activity, in the case where ensureing that wrist joint obtains fully taking exercise, it is to avoid secondary injury;Movable model can also be adjusted
Enclose, doctor or patient oneself is easily adjusted scope of activities according to recovery extent.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of wrist joint fixing device with spring, including a palm connect band 1, proficiency
Arm connecting portion 2, an adjustment portion 3, a front rod 4 and a rear connecting rod 5;
As shown in figure 4, the palm connect band 1 is fabricated from a flexible material, its top is provided with a connecting plate 11;The palm connects
Tape splicing 1 is used to be connected with the palm of patient;
As shown in figure 5, the arm connecting portion 2 is the platy structure that section is arc, two pairs of connecting holes 22 are provided with,
As shown in Figure 2 and Figure 3, the arm connect band 21 is connected with the connecting hole 22, as shown in figure 5, the top of arm connecting portion 2 is also
It is provided with a chute 23;The arm connect band 21 is used for the arm that the arm connecting portion 2 is fixed on to patient;

One connection annulus 34;
As shown in fig. 6, the inner side of the connection annulus 34 has been evenly arranged four springs 341, the spring 341 is justified along the connection
The radial arrangement of ring 34;
The connection strap 31 is slidably connected with the chute 23;The front and back position of the adjustment portion 3 can be easily adjusted, conveniently not
Patient with arm length uses, and also the palm of patient can be facilitated up and down;
As shown in Fig. 7, Fig. 2, Fig. 3, the front rod 4 is " L " shape structure, its front end and the ball-joint of connecting plate 11, in
Portion and first engaging lug 32 are hinged, the front end ball-joint of rear end and the rear connecting rod 5;
As shown in Fig. 8, Fig. 2, Fig. 3, the middle part of the rear connecting rod 5 with second engaging lug 33 is hinged, rear end is provided with four
Individual connection projection 51, this four connection projections 51 are connected with the spring 341 respectively.
When palm stretches value, the equal length of four springs 341, the tail end of the rear connecting rod 5 is located at the connection annulus 34
Center, the tail end stress balance of rear connecting rod 5;When the palm of patient is in certain angle with forearm, pass through the preceding connection
Bar 4 and rear connecting rod 5 can drive the off-center position of rear connecting rod 5, so that its tail end force unbalance, further may be used
The palm of patient is set to experience certain resistance, it is to avoid the moving speed of palm is very fast, so as to avoid secondary fracture.
As shown in fig. 6, the surrounding of the connection annulus 34 has been evenly arranged four regulating bolts 342, the edge of regulating bolt 342
The radial arrangement of the connection annulus 34 and annulus 34 is connected with this it is threadedly coupled;The spring 341 is connected with the regulating bolt 342
Connect.At the initial stage recovered in wrist joint, the regulating bolt 342 can be screwed, the spring 341 is compressed, makes carpal scope of activities
Smaller, movable resistance is larger;In the later stage recovered in wrist joint, the regulating bolt 342 can be unclamped, the length for the spring 341 that lengthens
Degree, makes that carpal scope of activities is larger, and movable resistance is smaller;The activity of different directions can also be adjusted, such as wrist joint is upward
Movable scope it is larger when, the amplitude that can unclamp the regulating bolt 342 of upside is larger, downward movable of wrist joint
When scope is larger, the amplitude that can unclamp the regulating bolt 342 of downside is larger;This adjustable structure more conforms to wrist
The recovery rule in joint, thus it is more beneficial for carpal exercise and recovery, additionally it is possible to avoid secondary injury;Regulative mode letter
Single, adjusting the operation of the regulating bolt 342 can be completed by the doctor in charge of patient, can also be completed by patient.
As shown in fig. 6, the inner side of first engaging lug 32 is provided with one first ball recess 321;Second engaging lug 33
Inner side be provided with one second ball recess 331;
As shown in fig. 7, the middle part of the front rod 4 is provided with one first spherical protuberances 41;
As shown in figure 8, the middle part of the rear connecting rod 5 is provided with one second spherical protuberances 52;
As shown in fig. 6, the diameter for being smaller than first spherical protuberances 41 between two the first engaging lugs 32;This first
Spherical protuberances 41 are arranged in first ball recess 321;
As shown in fig. 6, the diameter for being smaller than second spherical protuberances 52 between two the second engaging lugs 33;This second
Spherical protuberances 52 are arranged in second ball recess 331.
This structure can both make wrist joint horizontal anomalous movement, can also tear open the front rod 4 and the rear connecting rod 5
Unload, consequently facilitating patient wears the wrist joint fixing device that this carries spring.
