Abstract
An appaatus for restoring the functions of condyle joint and knee joit is composed of a bed frame, a connecting rod mechanism consisting of several connecting rods linked by a certain logic, a driving rod, and an electric motor linked to said driving rod.
Description
Technical field:
The present invention relates to a kind of joint function recovery device, can be used for the recovery of patient's limb function.
Background technology:
For the patient of fractured leg owing to be subjected to the fracture or limbs and each periarticular fascia, muscle excessive distortion or the tractive that cause after in various degree the outside violence, cause and damage or tear, make injury congestion swelling, sharp ache, limitation of activity.
At present, hospital's widely used trouble limb functional rehabilitation machine, can help the patient to carry out the functional recovery training in later stage, this recovery machine structure as shown in Figure 1, this mechanism is simple four-bar mechanism, include the connecting rod 1 that is connected in fixing point A end and can rotates around it, the connecting rod 2 that is connected with connecting rod 1, foot rest; Motor-driven mechanism drives the linkage of whole device, and the rod member of motion leg-supporting motion is two bars, is provided with between two bars and places the fixedly belt of suffering from limb.This mechanism is called CPM---and knee joint function recovers machine, and C spot welding is dead, can be considered a slider-rocker mechanism; B is a driving link, and the D point is moved around A.The patient with femoral head, be that leg portion places on the bar 1, tibia, be that lower leg portion places on the bar 2, foot is placed on and is positioned at 4 li of the shoe covers that C orders, under the driving of motor driver, reciprocating motion about slide block 8 carries out in guide rail 9, thereby patient's shank muscles and bones is taken exercise, to reach the effect of functional rehabilitation.This CPM machine defective is more, at first motion and motor integration, and the driven by motor with 50W exists personal safety hidden danger, and the electric machine controller complexity, and whole installation cost is higher, and volume is big, heaviness; When patient uses, move on the bed, also will carry down after using up by nurse or doctor, not only time-consuming but also require great effort; Secondly the rod member of leg-supporting motion is two bars, will suffer from the middle of limb is fixed on belt, between belt and the muscle slit is arranged like this, makes the final angle of leg exercise can not reach ideal 120 and spends; Moreover patient's foot is placed in the shoe cover, can only the activity knee joint, to ankle joint without any effect.This CPM machine structure is too complicated, and inconvenient activity profit, and quickreturn characteristics is arranged especially during the accelerated motion of its positive stroke, will produce very big inertia force, this for tibia or fibula not fully the patient of healing be difficult to bear.
Summary of the invention:
The objective of the invention is to overcome the existing shortcoming of suffering from limb functional rehabilitation machine, designed a kind of move soft, can make ankle joint and knee joint obtain the folding joint function recovery device that moves simultaneously.
The present invention is a kind of joint function recovery device, and its structure is seen Fig. 3-6.This device includes the connecting rod 1 that is connected in fixing point A end and can rotates around it, the connecting rod 2 that is connected with connecting rod 1, foot rest; Drive the connecting rod mechanism movement of whole device by motor-driven mechanism, be characterised in that: the rod member of motion is single pole, includes the connecting rod 10 that an end is connected with connecting rod 2, the other end is connected with bedstead 14; One end is connected in the junction of connecting rod 1, connecting rod 2, the connecting rod 15 that the other end is connected with drive rod 16; Drive rod 16 is connected with motor 5, whole link motion mechanism is arranged on the bedstead 14, the A end of connecting rod 1 and the B end of connecting rod 10 are separately positioned on the same long side surface place of bedstead by known technology, this place, side of bedstead is provided with the line style groove 17 that is equipped with connection, the B end of connecting rod 10 is arranged on the position of groove 17, the B end that changes connecting rod 10 is in the position at groove 17 places, can change the distance between the B end of the A end of connecting rod 1 and connecting rod 10.
The present invention adopts known technology to make bar 1, bar 2, bar 10 and edge of bed form a plane quadrilateral structure in perpendicular.The angle of bar 2 and bar 1 extended line direction, be the angle of people's shank and thigh extended line direction from 0 ° to 120 °, just people's lower limb is done the scope of curvature movement, places motor-driven mechanism under the bed to drive the connecting rod mechanism movement of whole device.At B point place, along the bedside direction B point is placed in the different grooves, can change the distance between A point and the B point, also just can change the scope of people's lower limb movement angle.
Described joint function recovery device is provided with in the junction of connecting rod 2 and connecting rod 10 and is connected with pedal unit 18 by connecting rod 11.
In the described joint function recovery device respectively the middle section position place at connecting rod 1 and connecting rod be provided with lower limb supporting plate 12, to support thigh and shank.
Described joint function recovery device also is connected with an articular branches strut 13 in the junction of connecting rod 1, connecting rod 2, connecting rod 15.
The present invention adopts known technology to make bar 1, bar 2, bar 10 and edge of bed form a plane quadrilateral structure in perpendicular.The angle of bar 2 and bar 1 extended line direction, be the angle of people's shank and thigh extended line direction from 0 ° to 120 °, shank is supported by the capper who stretches out, it is crooked to make knee joint reach ideal 120 degree.Just people's lower limb is done the scope of curvature movement.At B point place, along the bedside direction B point is placed in the different grooves, can change the distance between A point and the B point, also just can change the scope of people's lower limb movement angle.
Just patient's femoral head, leg portion placed on the bar 1 when the present invention used, tibia, be that lower leg portion places on the bar 2, arch of the foot is pedaled on pedal 18, when motor rotates, driving bar 16 moves in a circle in perpendicular, bar 16 drives bar 15 motions, thereby drives bar 1, bar 2 motions, and bar 10 is motion under bar 2 drives also.Because patient's foot is placed on the pedal, the underfooting also can be stressed when making leg exercise, and to the motion of ankle joint, the recovery of the metatarsal on some feet, shank etc. also can play a role in addition.
Entire mechanism of the present invention is a force-increasing mechanism, and mechanism only needs a buncher to drive, and cost is reduced greatly.This motor places ground, separates with movement parts, and the A point, the B point is fixing in bed, and collapsible the packing up of whole motion of time spent do not saved the space, and be laborsaving.Especially the patient of need with this device directly can be placed on this special bed in the ratio of patient with bone fracture quantity than infirmary.
Further specify technical scheme of the present invention below in conjunction with drawings and Examples.
