Description
Technical field
This utility model relates to technical field of medical instruments, specifically the passive extension treatment apparatus of a kind of knee joint.
Background technology
At present, the function skin protection of knee joint being stretched to function limitation patient does not draw attention, and has a strong impact on the functions such as the daily life of diseases of knee joint patient, walking, motion, at present, does not have the passive extension treatment apparatus of special knee joint.
Through retrieval, CN203861530 discloses a kind of utility model patent of the passive extension treatment apparatus of knee joint of orthopaedics, it comprises the framework of base plate, base plate is fixedly connected with framework, in the frame tube that base plate is parallel to two of opposite, what be nested is connected with upper platelet, an internal thread hole is had in upper platelet, be threaded in internal thread hole threaded rod, threaded rod is vertical with base plate, threaded rod is rotatably connected to arc close to one end of base plate, threaded rod is connected to the convex surface of arc, its deficiency is: unreasonable structure, inconvenient operation, patient's labor intensity is in use large.
Summary of the invention
The purpose of this utility model solves above-mentioned the deficiencies in the prior art, provides a kind of novel structure, the passive extension treatment apparatus of easy to operate, that labor intensity is low knee joint.
This utility model solves the technical scheme that its technical problem adopts:
The passive extension treatment apparatus of a kind of knee joint, comprise base plate and framework, it is characterized in that being provided with servomotor, bearing, control device, eccentric cam, positioning key, rotating shaft and bracing frame, described rotating shaft is positioned at framework, described rotating shaft one end is fixedly connected with the servomotor be fixed on framework, the other end is fixedly connected with bracing frame lower end through bearing, described rotating shaft is provided with and is axially arranged with positioning key, described eccentric cam is fixed in rotating shaft through positioning key, support frame as described above upper end is fixedly connected with framework top, described servomotor is connected with control device, rotate under the driving of servomotor to make described eccentric cam, and then carry out passive repeatedly pressing down action of upspringing to patient, the fast quick-recovery of knee joint is made to stretch function.
Eccentric cam described in the utility model is that end face is provided with plural rotational shaft insertion hole along long diametric(al), and described rotational shaft insertion hole lateral symmetry is provided with positioning spline, is beneficial to adjust knee joint exercise stroke by the rotational shaft insertion hole that grafting is different.
Eccentric cam described in the utility model is made up of left half cam body and right half cam body, and described left half cam body is fixedly connected with through clamping screw with right half cam body, to reach easy to operate effect.
This utility model, owing to adopting said structure, has the advantages such as novel structure, easy to operate, labor intensity is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of eccentric cam in this utility model.
Reference numeral: base plate 1, framework 2, servomotor 3, eccentric cam 4, positioning key 5, rotating shaft 6, bracing frame 7, control device 8, rotational shaft insertion hole 9, positioning spline 10, left half cam body 11, right half cam body 12, clamping screw 13, sliding sleeve 14.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further illustrated:
As shown in drawings, the passive extension treatment apparatus of a kind of knee joint, comprise base plate 1 and framework 2, described base plate 1 and framework 2 are prior art, this does not repeat, it is characterized in that being provided with servomotor 3, bearing, control device 8, eccentric cam 4, positioning key 5, rotating shaft 6 and bracing frame 7, described rotating shaft 6 is positioned at framework 2, described rotating shaft 6 one end is fixedly connected with fixing servomotor 3 on the frame 2, the other end is fixedly connected with bracing frame 7 lower end through bearing, described rotating shaft 6 is provided with and is axially arranged with positioning key 5, described eccentric cam 4 is fixed in rotating shaft through positioning key, support frame as described above 7 upper end is fixedly connected with framework 2 top, described servomotor 3 is connected with control device 8, rotate under the driving of servomotor 3 to make described eccentric cam 4, and then carry out passive repeatedly pressing down action of upspringing to patient, the fast quick-recovery of knee joint is made to stretch function.
Eccentric cam 4 described in the utility model is that end face is provided with plural rotational shaft insertion hole 9 along long diametric(al), and described rotational shaft insertion hole 9 lateral symmetry is provided with positioning spline 10, is beneficial to adjust knee joint exercise stroke by the rotational shaft insertion hole that grafting is different.
Eccentric cam 4 described in the utility model is made up of left half cam body 11 and right half cam body 12, and described left half cam body 11 is fixedly connected with through clamping screw 13 with right half cam body 12, to reach easy to operate effect.
This utility model can overlap on described eccentric cam 4 sliding sleeve 14, is beneficial to avoid causing damage to skin.
This utility model in use, first the range end face of eccentric cam 4 is pressed down knee joint, to reach maximum knee joint ability to bear, eccentric cam 4 is arranged in rotating shaft 6 by the rotational shaft insertion hole 9 then on corresponding eccentric cam 4, by positioning key 5 and positioning spline 10, eccentric cam 4 is fixed in rotating shaft 6, like this, the functional training of upspringing can be repeatedly pressed down to knee joint by eccentric cam 4, when training is stretched flexibly to knee joint, again eccentric cam 4 is pulled down, rotating shaft 6 is inserted into again in next deep rotational shaft insertion hole 9, repeat above-mentioned action again to train, knee joint is made progressively to expand stretching, extension angle, until recover.
This utility model, owing to adopting said structure, has the advantages such as novel structure, easy to operate, labor intensity is low.
