Description
Technical field
The present invention relates to the handle that a kind of hand and wrist motion dysfunction patient carry out the rehabilitation supplemental training, particularly a kind of and driving and the supporting handle that carries out carpal joint and articulations digitorum manus training of damping unit.
Background technology
The training of hand and wrist is to stimulate by motion, improves a main rehabilitation maneuver of wrist hands movement dysfunction patient moving function.The finger wrist is stretched rehabilitation training handle in the wrong and is used for fixing palm or finger, and the moment of torsion transmission between guarantee and driving and the damping unit, finishes the training action of requirement.
Human body mostly all needs to point the participation with wrist under the situation when finishing fine movement.Spinal cord injury, burn back muscle contracture upper limb disorder patient, upper limb disorder patient behind apoplexy, the cerebral trauma, and there is the obstacle of wrist hands movement function in the patient behind the hand injury, upper limb damage, replantation of amputated finger, need carry out exercise rehabilitation training.According to the rehabilitation medicine document, wrist hands movement function can be divided into: wrist oar lateral deviation, cubit lateral deviation, wrist bend and stretch, to the palm, between referring to, referring to the bending and stretching of metacarpophalangeal joints, forearm revolve preceding and supination etc.According to clinical practical experience and human physiological structure's characteristics, the training of wrist hands should be according to descending principle, promptly at first carries out the big joint training of wrist hands, after the former has had certain basis, increase littler joint, the more training content of fine movement more gradually.Therefore, the training in wrist and the big joint of finger is the important content of wrist hand rehabilitation training.Wherein, finger closes up the flexor that bends and stretches (joint of only bending and stretching finger root) and wrist, is the main training content in the big joint of training wrist hands.
Traditional exercise rehabilitation training needs the physiatrician and participates in, and provides support and driving to patient's hand by it.Because this artificial supplemental training expends a large amount of human resourcess, and, can't ensure that the patient obtains enough, quantitative motion stimulation, so in the last few years, the development of athletic rehabilitation assistive device more and more obtained paying attention to.Be used for fixing and drive the patient to suffer from chirokinesthetic handle be requisite actuating device in the wrist hands movement exercise equipment.
Because human body wrist hands structure is very complicated, degree of freedom is many, has brought a lot of difficulties for the design of handle.Chief reason is: handle will ensure on the one hand to hand and the effective fixed support of wrist, also will ensure the free activity in the joint that needs training on the other hand.Wrist and finger be around big joint when doing flexion movement, and the position of kinematic axis is in continuous variation, so, when suffering from hands, need fixed parts have corresponding degree of freedom fixing, prevent suffering from the damage of hands.In addition, most of hand exercise dysfunction patient, especially hemiplegic patient, a little less than the expansion service of finger and wrist, flexing trend is obvious, during training, need or not the finger-joint of flexing to keep straight configuration by external force constraint.Could finish training action so effectively and suppress spasm.Existing can being used for auxiliary finished finger and wrist is bent and stretched in the handle of training, has only Smith﹠amp; In the Kinetec wrist hand passive exercise device of Nephew company, designed two and be used for wrist separately and point the handle that bend and stretch in big joint.First handle arrangement is two nip rolls, and second handle is a fingerstall of fixing and rotating simultaneously with handle relative to handle position.Bilateral gripper arrangement can't limit the tetanic property flexing trend of finger.Fixedly the most significant shortcoming of fingerstall is that it can't adapt to the variation that the wrist hands bends and stretches kinematic axis position in the process.
According to the anatomical structure of palm and wrist joint, when all joints are 180 degree straight configurations, form a palm plane.Palm plane is with the ball in two of the space around the palm.Palm one side hemisphere is the range of activity of finger, and the motion of finger end has a plurality of degree of freedom in this space.Fixedly during palm, the partial constraints of palmar side can't realize effectively fixing, needs the fixed form of plane restriction.Each joint of finger all is subjected to the constraint of self structure on the back of the hand direction, under the fixed condition of carpal joint, can't make the hemisphere active movement of finger in the back of the hand one side by the adjustment of finger-joint angle.So dorsal side just can reach the constraint purpose by a more comfortable pressure roller of use.In sum, bend and stretch in the design of training handle, should adopt the palmar side plane restriction, the fixed form of dorsal side line constraint at finger and wrist.And in existing handle, also there is not this project organization.
