Abstract
The invention discloses a knee joint rehabilitation instrument, mainly consisting of a motor, a worm-gear pair reducer and a pedal motion mechanism connected with a reducer output end. The knee joint rehabilitation instrument is characterized in that the pedal motion mechanism comprises a crank arm and a pedal arranged on and vertical to the crank arm; more than one linkage structure for the selection of an installation position of the pedal is arranged on the crank arm. The invention enlarges the action range of the knees of a patient with the passive actions of the knees in a range of 0-140 DEG, and can prevent the muscle soreness easily caused by machine hauling by the conventional CMP equipment so as to greatly improve the rehabilitation effect.
Description
Technical field
The invention belongs to athletic rehabilitation equipment, especially passive type motion of knee joint rehabilitation equipment is made the field.
Background technology
Generally to fix behind articular ligament or the operation on joint, very easily cause adhesion of knee joint muscle even ankylosis, have a strong impact on patient's quality of life the affected part.Therefore, postoperative carries out functional rehabilitation exercise in early days, be to make to hinder the key that limb returns to one's perfect health, crossing method of rehabilitation both domestic and external (1) the artificial maneuver knee joint activity that mainly contains at present takes exercise, advantage is can be according to patient's situation strength of adjustment and activity point of view, and shortcoming is that labor intensity requires high common people not grasp the requirement that is difficult to satisfy all patients to therapist's technical ability greatly.(2) instrument supplemental training, the topmost rehabilitation maneuver and the instrument of various big hospital employing at present are exactly CPM (contineous passive motion) mobilizer, just continuous passive motion machine.The seventies in 20th century, the Canada doctor has proposed the notion of the lasting passive activity of osteoarthrosis postoperative through lot of experiments, utilize cartilage joint to continue the passive activity theory, adopt lower limb CPM mobilizer that knee joint peripheral fracture surgery patient is carried out rehabilitation, have certain curative effect.But the weak point that CPM takes exercise is: the exercise of (1) CPM mobilizer will be suffered from lower limb and closely will be fixed on the active lever, if improper use is easy to cause the fracture end displacement that is fixed.Shank and machine can increase the stress of fracture when fixedly tension uses, cause that easily internal fixation is loosening; (2) the CPM mobilizer is because the restriction of himself structure, in addition different patients height and the length thickness of lower limb have nothing in common with each other, and patient's shank and CPM mobilizer mated condition at the volley, although the maximum machine angle of CPM mobilizer reaches 120 degree, but the patient in use, the real activity point of view of knee joint is confined to 0 to 90 degree, therefore the patient only relies on the CPM mobilizer to perform physical exercise, maximum actual rehabilitation angle only is confined to can not satisfy the demand of in patient's real life shank being bent and stretched angle far away in 90 degree.
Summary of the invention
In view of the above shortcoming of prior art, the objective of the invention is to design a kind of novel passive type motion of knee joint rehabilitation equipment, make it to overcome the above shortcoming of prior art.
The objective of the invention is to realize by following means.
A kind of knee joint rehabilitation instrument, mainly by motor, formed by worm and wormwheel supplementary reduction and the motion of foot mechanism that connects with the decelerator outfan, described motion of foot mechanism by connecting lever with place on the connecting lever also vertically disposed with it pedal to form; Connecting lever is provided with the coupling arrangement of selecting the installation site more than one for pedal.
Structure of the present invention is simulated kneed at ordinary times self-movement mode, put-lower limb advanced in years-put ground, just in time be a circular motion, what the strength that in use can not cause muscle to pull owing to machine produced aches the time of the reconditioning that can extend.Novel rehabilitation instrument of while has overcome the CMP mobilizer and has promptly only spent shortcoming effectively to 90, has increased range of activity, can satisfy the knee folding range of activity of 0-140 degree, makes the patient can increase substantially rehabilitation efficacy.In addition, connecting lever directly is fixed on the output shaft of worm type of reduction gearing when guaranteeing that motor does not rotate, and output has been guaranteed safe in utilization in self-locking state.
Description of drawings
Fig. 1 is the outside drawing of the embodiment of the invention.
Fig. 2 is the vertical view of this Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in the figure, circumference formula motion knee joint rehabilitation instrument, base 1 is welded by steel plate and square steel, and boring is used for fixed electrical machinery 2 and worm and wormwheel supplementary reduction 6 on steel plate.Motor 2 is connected transmission by belt pulley 3,5 with belt 4 with decelerator 6.Connecting lever 7 is contained on the output shaft of decelerator 6 and can freely rotates by positive and negative 360 degree with output shaft.Pedal 8 can be fixed on any hole of connecting lever as required by bolt and can freely rotate by 360 degree.Motor 2 can stepless speed regulation and rotating control.Connecting lever is provided with the connecting through hole of selecting the installation site more than one for pedal.
The present invention adopts the model of action of new structure and circular motion, in the connecting lever design, adopt connecting lever length multistage adjustable, promptly bore and a plurality ofly be used for fixing foot-operated hole so that regulate the correct position of pedal at the connecting lever length direction, increase the range of activity of machine, guarantee that this machine is fit to the people's of different instructions for uses selection.The patient is at the rehabilitation initial stage, and kneed range of activity is smaller, the effective length of connecting lever is adjusted to the shortest, and the range of activity of machine is also minimum thereupon.If patient's initial stage activity point of view still can not reach the range of activity of one-period, can also simulate the model of action in CPM machine friction joint at first, range of activity changes the reversible motion repeatedly of low-angle half period into, can guarantee to use the rehabilitation of patients requirement at initial stage like this.Along with the increase of activity point of view, the effective length of connecting lever can be strengthened, range of activity also strengthens thereupon.Because new structure and the adjustable design of connecting lever, rehabilitation effective range can be higher than 140 degree, shuttling movement type knee joint rehabilitation instrument so range of activity can satisfy the exercise needs of any angle of patient.Can be effective to the rehabilitation angle of 0-140 degree, be a kind of high-tech, high-quality, product cheaply, small and exquisite portable, making things convenient for the patient to be in just can use, and occupation mode is simple, safety, can reduce the expense that the patient carries out rehabilitation training in hospital significantly, and the operation of simple specialty simultaneously can also the amount of reaching property effect, the hospital of any area, any condition and family can enjoy the level of the rehabilitation of specialist hospital, can improve the effect of rehabilitation significantly.
