A kind of limb rehabilitating device of multi-joint interlock
This utility model belongs to limb rehabilitating equipment, specifically a kind of limb rehabilitating device of multi-joint interlock.
China is populous nation, also is simultaneously the developing country that medical level falls behind relatively, because the group of handicapped that disease, sport injury and unexpected injury cause has quite high ratio and absolute quantity; And China is one of hotspot of apoplexy, and the patient of about 70%-80% leaves deformity in various degree in survivor.Obstacle of limb movement brings many inconvenience in life not only for patient self, brings huge adverse effect also for family and society.For this class patient, it is very important and crucial medical procedure that rehabilitation training is carried out at its disabled position, carries out early rehabilitation training and can greatly reduce disabled probability.Rehabilitation is a kind for the treatment of procedure on Orthopedic Clinical, in order to reduce the invalidity after the orthopaedics illness is treated, its objective is restore funcitons, namely on the basis for the treatment of, emphasize to prevent contracture, the application training method, the exercise muscle strength stimulates potential ability to recover or the compensatory function of having lost.Just generally speaking, the prognosis effect of an operation, half depends on postoperative rehabilitation.Therefore, rehabilitation is for being significant on the Orthopedic Clinical and acting on.
In traditional rehabilitation, the therapist carries out man-to-man rehabilitation training to the patient by doing and illustrating, the training effectiveness of this mode and training strength are difficult to guarantee, the training effect is subject to the impact of therapist's level, even in conjunction with already present comparatively ripe joint recovering device equipment (CPM) in the market, generally adopt motor as driver, pass through screw rod transmission, the rotation that changes motor is the linear translational motion of nut, drivening rod is realized the flexion and extension in joint, this device for rehabilitation can only carry out easy joint rehabilitation training, although can obtain certain rehabilitation efficacy, but still lack the rehabilitation training that multi-joint links, be difficult to rehabilitation is optimized and obtains optimum efficiency.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, the limb rehabilitating device that provides a kind of multi-joint simple in structure, practical and convenient, respond well, that cost is low to link.
The technical scheme that this utility model adopts is:
The limb rehabilitating device of a kind of multi-joint interlock of this utility model, comprise three motors and support, it is characterized in that: support is comprised of shoulder joint travel(l)ing rest, exercising elbow joint support, wrist joints moving support, respectively by three motor-driven, three travel(l)ing rests are simulated respectively shoulder, elbow, carpal joint natural motion track and are made integrated link gear, by microcomputerized control.
This utility model shoulder joint travel(l)ing rest, larger length is arranged, its motion field can cover the range of movement of normal person's upper limb, suffers from that limb is finished on a large scale, rehabilitation exercise training significantly so can drive the patient, thereby can fully provide the nervus centralis rehabilitation required Motor stimulation.
This utility model exercising elbow joint support drives the revolution transmission synchronously with drive motors, has guaranteed the kinematic accuracy of elbow joint motion bracket, and the speed of service is sustainable regulates stably, to adapt to the reconditioning requirement of different phase.
This utility model wrist joints moving support adopts the gyration mode, and simulation wrist natural motion track adopts microcomputerized control, and the range of activity of wrist can be set easily.
This utility model has adopted three motors to finish a whole set of motion, has higher control performance, realizes multiple training mode; Adopt the gyration mode to simulate shoulder, elbow, carpal joint natural motion track, can satisfy the patient and suffer from the needs that limb planar carries out two-dimentional compound motion, and simple in structure, be conducive to driving and the control of multi joint motion support.

Fig. 1 is this utility model structural representation.
The specific embodiment
As shown in Figure 1, a kind of limb rehabilitating device of multi-joint interlock, comprise three motors and support, it is characterized in that: support is comprised of shoulder joint travel(l)ing rest 1, exercising elbow joint support 2, wrist joints moving support 3, driven by shoulder joint motor 4, elbow joint motor 5, carpal joint motor 6 respectively, can corresponding simulation shoulder, elbow, carpal joint natural motion track.Unified three motors of control of coordinating of micro computer drive corresponding travel(l)ing rest, synthetic shoulder, elbow, carpal combined action.
This utility model adopts the gyration mode to drive shoulder joint travel(l)ing rest 1 by shoulder joint motor 4 and rotates, and realizes shoulder joint kinesitherapy; Elbow joint motor 5 and the motion of exercising elbow joint support 2 synchronous revolvings are realized the elbow joint motion; Drive wrist joints moving support 3 after carpal joint motor 6 rotates, realize wrist joints moving.
This utility model drives the patient and suffers from limb according to predetermined movement locus, carries out the rehabilitation action training, and is succinct light and handy, has certain motility, improves the kind of training action, increases movement range, each joint of trouble limb trained in a plurality of planes.
