Description

Rehabilitation training device for lower limb arthrosis
Technical field
This utility model belongs to a kind of rehabilitation medical apparatus, is specifically related to a kind of rehabilitation training device for lower limb arthrosis.
Technical background
The continuous passive motion of human synovial is the effective ways that prevent the postoperative joint accretion, promote the joint motions functional rehabilitation.Rehabilitation training device for lower limb arthrosis based on this method exploitation at home and abroad is used widely at present.But existing most of joint of the lower extremity rehabilitation device all exists the problem that the big leg support centre of gyration and human hip run-on point do not overlap, cause patient's joint of the lower extremity pressure increase in the motor process, and skin slippage on the rehabilitation device, wipe movingly, bring the extra pain of injury to the patient.Often the rehabilitation device is designed to have the structure of one-sided thigh support frame at the improvement project of this problem, this is owing to the interference of patient's lower part of the body perineum part pin joint to be set at this position; To adjust conversion through the left and right both sides of being everlasting when such rehabilitation device uses, make troubles to use; And, easily cause device deformation owing to adopt asymmetric monolateral supporting construction.Patent ZL94227560.8 has proposed to use improving one's methods of two parallel-crank mechanisms and harmonic drive mechanism, and patient's hip joint run-on point is overlapped with the imaginary hinge contact of pair parallelogrames, when avoiding mechanism kinematic to the interference and the skin injury of human body.This technology has had marked improvement from principle, but does not thoroughly address the above problem, because for different patients, because the difference of physical trait, its hip joint run-on point position is different, must consider how to adapt to this difference during the recovery training appliance for recovery design; In addition, because the imaginary hinge contact of two parallelogrames be can't see, how to determine that the mutual alignment of people and training aids still lacks effective means.
Summary of the invention
Deficiency at the prior art existence, this utility model adopts two parallel-crank mechanisms to add the version of adjustable plate, and be equipped with telescopic scale, develop a kind of rehabilitation training device for lower limb arthrosis, it is characterized in that to adapt to different patient's physical traits, realize that patient's hip joint run-on point accurately overlaps with training aids thigh carriage turns center, and regulate directly perceived, easy.
Followingly narrate with reference to 1~4 pair of structural principle of the present utility model of accompanying drawing.Rehabilitation training device for lower limb arthrosis mainly has casing 1, rocking bar 2, rocking bar 3, frame 4, bridge screw 5, adjustable plate 6, flexible scale 7, big leg support 8, connecting rod 9, thigh adjusting rod 10, connecting rod 11, joint 12, shank carriage 13, push rod 14, shank adjusting rod 15, foot carriage 16, adjustable plate pull bar 17, rocking bar protective cover 18 and connecting rod protective cover 19.Adjustable plate pull bar 17 with about two adjustable plates 6 fixed, adjustable plate 6 is hinged with rocking bar 2, rocking bar 3 respectively, one of two hinges on frame 4 and the adjustable plate 6 are hinged and form compound hinges, as Fig. 3 or shown in Figure 4; Have one section annular groove on the adjustable plate 6, bridge screw 5 passes annular groove and adjustable plate 6 can be fixed on the frame 4; Constitute two parallel-crank mechanisms by adjustable plate 6, rocking bar 2, rocking bar 3 and connecting rod 9, connecting rod 11, big leg support 8; Flexible scale 7 is telescopic rods, is installed on the end cap of big leg support 8, and contraction state can be hidden in the hole of big leg support 8 down, fully after the elongation then the top overlap with the imaginary hinge contact 0 of pair parallelogrames, as shown in Figure 1; Thigh adjusting rod 10 is hinged by joint 12 with shank carriage 13, and angular transducer is equipped with in joint 12 inside.When determining the relative position of machine and human body, the flexible scale 7 that will be positioned at big leg outer side is earlier pulled out fully, unscrew the bridge screw 5 of both sides, by pulling adjustable plate pull bar 17, driving adjustable plate 6 rotates around compound hinges, make the top of flexible scale 7 with after the human hip run-on point overlaps in vertical fully, tighten bridge screw 5, the relative and frame 4 of adjustable plate 6 is maintained static.Make the center of rotation of joint 12 overlap by the extension elongation of regulating thigh adjusting rod 10, shank adjusting rod 15 again, can carry out rehabilitation training with the human body knee joint run-on point.Accident jams a finger when avoiding moving, and rocking bar protective cover 18 and connecting rod protective cover 19 are housed respectively on rocking bar and connecting rod.
Compare with existing rehabilitation training device for lower limb arthrosis, this utility model is owing to adopted the two parallel-crank mechanisms with regulatory function, guaranteed of accurate the overlapping of training aids thigh carriage turns center with patient's hip joint run-on point, enlarge the scope of application of training aids, and improved the effect of rehabilitation training greatly.
