Abstract
The invention discloses a pelvis mechanism for gait rehabilitation training. The mechanism comprises a base, a rocker, a junction box, a cover plate, a swing member, an extension shaft, a supporting plate, a supporting arm and the like, wherein the base can move up and down along a stand column of a robot to realize the degree of freedom for vertical movement at the pelvis; the junction box can swing left and right around the base through the rocker to realize the degree of freedom for left-right movement at the pelvis of a patient; the swing member can rotate around the junction box through two joint ball bearings to meet the twist motion, roll motion and pitching motion of the pelvis. According to the pelvis mechanism, the constraint to the patient can be effectively reduced, so that the patient can freely move the pelvis, the comfort of the training process is improved, the balance capacity is trained while the lower limb walking function is trained, and a better training effect is achieved.
Description
Technical field
The present invention relates to the rehabilitation medical instrument field, particularly relate to a kind of pelvis mechanism that can be used for the gait rehabilitation training.
Background technology
In recent years, aged tendency of population aggravation, various unsound life style and vehicle accident, industrial injury etc. constantly increase, and the patient of the walking function obstacle that is caused by apoplexy, spinal injury or contingency etc. has become the common colony of modern society.Except adopting medicine and operative treatment, what mainly rely on is naturopathy, namely carries out rehabilitation training to this class patient.
Link to each other with lumbar vertebra on the pelvis of human body, lower and femur consists of hip joint, it is the bridge between spinal column and the lower limb, the weight of health is delivered to lower limb by pelvis, the vibrations of lower limb also are uploaded to spinal column by pelvis, therefore, it both encircled as one of spinal column and moved, and did with respect to lower extremity movement take hip joint as axle again.Normal human's pelvic area has six-freedom degree, be respectively the reversing of hip joint place, pitching and three rotational freedoms of inclination and walking process midpelvis about, front and back and the one-movement-freedom-degree of three directions up and down.Studies show that, play important balanced action in the various daily routines such as pelvis is walked at human body, wears the clothes, had a bath, motion, when pelvis produces improper movement locus, will directly have influence on the motion feature of gait.According to the neural facilitation know-why, strengthen the motor function that the pelvis control ability can promote lower limb, the training of pelvis can improve the balanced capacity of health both sides, accelerates hemiplegic patient's rehabilitation efficient.Existing lower limb rehabilitation robot majority does not have pelvis mechanism, and the patient is subject to very large constraint in training process, and the health of freely activity oneself has been ignored the importance of balance training to hemiplegia patient, has affected the rehabilitation process.
Summary of the invention
The object of the invention is to solve the deficiency that above-mentioned prior art exists, a kind of pelvis mechanism for the gait rehabilitation training is provided, can reduce the constraint to the patient, make the patient can the freely-movable pelvis, satisfy pelvis about, about, reverse, five degree of freedom such as inclination and pitching, improve the comfort level of training process, balance training ability in training lower limb walking function reaches better training effect.
For achieving the above object, the present invention has adopted following technical proposals:
A kind of pelvis mechanism for the gait rehabilitation training comprises a pedestal, two rocking bars, a connecting box, a cover plate, a swing component, four outrigger shafts, two gripper shoes and two support arms; It is characterized in that: described rocking bar and described connecting box and described pedestal are hinged, described cover plate covers on connecting box, described swing component is positioned at the below of connecting box bottom and is flexibly connected with connecting box, and the both sides of swing component respectively have the outrigger shaft of two position-adjustables, this outrigger shaft to be fixedly connected with a support arm by a gripper shoe; Pedestal is connected with robot, can move up and down along the column of robot, realizes the degree of freedom that moves up and down at pelvis place; Connecting box can rock from side to side around pedestal by rocking bar, to realize the move left and right degree of freedom at patient's pelvis place; Swing component can rotate to satisfy the reversing of pelvis, inclination and elevating movement around connecting box.
The structure that described rocking bar and described connecting box and described pedestal are hinged is: respectively there is up and down a hole at the two ends of described rocking bar, two deep groove ball bearings and a thrust ball bearing are housed in each hole successively, deep groove ball bearing will be rotatably assorted with fixing rotating shaft on pedestal and the connecting box, reduce friction, thrust ball bearing is used for bearing the power of vertical direction.
Described swing component with the structure that connecting box is flexibly connected is: described swing component links to each other with connecting box by two oscillating bearings, the upper end of oscillating bearing is fixed in connecting box by a joint bearing block and a joint shaft bearing sleeve, the lower end links to each other with swing component by a clamping screw, oscillating bearing can rotate on four sides around the center, realize the reversing of pelvis, inclination and elevating movement, adopt two oscillating bearings that vertically are arranged side by side, can increase mechanism bearing capacity and the restriction reverse with the scope of elevating movement not too large, in order to avoid the patient is damaged; Scope gapped between swing component and the connecting box, can regulate roll motion by the size of adjusting play.
Described outrigger shaft is inserted in the hole of swing component both sides, and outrigger shaft is fixed by bolt and gripper shoe, and support arm is bolted on the gripper shoe and is clamped in patient's pelvic on both sides; Outrigger shaft can outwards stretch, and regulates the distance between two support arms being attached thereto, to adapt to different patients' build, adjust distance afterwards by bolt with the fixing anti-skidding of outrigger shaft.
The present invention is compared with existing technology, has following apparent outstanding substantive distinguishing features and significant technological progress:
The present invention is simple in structure, and is easy to use.During use, support arm is held on patient's pelvic on both sides, about the process midpelvis mechanism that the patient carries out gait rehabilitation training can guarantee patient's pelvis, about, reverse, five degree of freedom such as inclination and pitching, patient's pelvic area is not carried the baby, can freely-movable, training patient's equilibrium function in training shank walking function.And present existing lower limb rehabilitation robot majority does not have pelvis mechanism, and training process is larger to patient's constraint, and the patient is the health of activity oneself freely, and equilibrium function can not get training, affects rehabilitation efficient.
