Abstract
The utility model relates to an interactive swing type joint. For the existing single-shaft joint mounted at the inner side of dual-side thigh orthesis, the top and bottom difference between the rotation axis and the hip joint axis of a human body is very large, so that a patient cannot step forward and walk lightly and smoothly. In the interactive swing type joint, a pair of gears is arranged in a U-shaped groove and a U-shaped rotation frame, a four-connecting-rod type structure is arranged at each side of a gear shaft, each four-connecting-rod type structure is formed by two end surface bearings, two shafts and two rotation boards at the same side, and the transient rotation axis of the joint is arranged corresponding to the position of a physiological hip joint. With the interactive swing type joint, the transient rotation axis of the joint is elevated, the rotation tends to be consistent with the flexion and extension movement of the joint, the step is light and smooth, the energy consumption of a patient is reduced, the walk ability, the blood circulation, the bone density, the cholesterol level, and the functions of the bladder and the intestinal tract the patient are improved, and the occurrences of bedsore, dyspepsia, urinary system infection, pneumonia and other complications are avoided.
Description
Technical field
This utility model belongs to the rehabilitation engineering technical field, is specifically related to a kind of mutual swing type joint.
Background technology
Orthosis is to be used to change the functional characteristic of neuromuscular and skeletal system or the device outside of structure.The development of orthosis technology and services has promoted the development of rehabilitation medicine, and people are regarded as the orthosis technology and one of naturopathy, operation treatment, the same four the important rehabilitation techniques of speech therapy.The existing inboard uniaxial joint of bilateral above-knee orthosis that is installed in; Gap is bigger up and down in physiological joint axle center when its movable machinery axle center and human body walking; Can produce mutual inharmonic negative effect; Light inadequately smoothness when the patient takes a step to walk has increased patient's physical consumption, influences the rehabilitation of patients training effect.
Summary of the invention
The purpose of this utility model provide a kind of be installed in the bilateral above-knee orthosis inboard, the physiological joint axle center consistent mutual swing type joint of the instantaneous axis of rotation heart during with human body walking, make patient's lighter smoothness of walking of taking a step, reduction patient physical consumption.
The technical scheme that this utility model adopted is:
A kind of mutual swing type joint includes rotor plate and rotating turret, it is characterized in that:
Described rotating turret is a U-shaped, is provided with two engaged gears in its U-lag, and the axial both sides of each gear are respectively arranged with a rotor plate, and two rotor plates of each gear and its axial both sides are connected on the rotating turret through the end face bearing;
Two rotor plates that are positioned at two gear homonymies are connected with same jam plate seat through an axle separately.
Central line distance between two axles is greater than the central line distance between two end face bearings.
Described jam plate seat is connected with jam plate through the jam plate assembly.
Described jam plate is provided with the jam plate fixing hole.
The utlity model has following advantage:
It is inboard that this utility model is installed in the bilateral above-knee orthosis, and easy installation and removal is quick, need not other people and help; Can be applicable to training of rehabilitation of patients such as paraplegia, poliomyelitis sequela, non-spastic cerebral palsy, spina bifida and spinal cord injury and practicality walking etc.; The position of its instantaneous axis of rotation heart raises by the physiology hip joint dimensional requirement of imagination; Rotation will be consistent with the flexion and extension in the joint of patient own; Therefore produced mutual inharmonic negative effect with regard to having changed in the past greatly because of gap about uniaxial joint axle center and the physiological joint axle center; The walking of taking a step can be felt light smoothness, reduces patient's physical consumption; Patient's functions such as ability to act, blood circulation, bone density, cholesterol levels, bladder and intestinal have not only been improved; And avoided the generation of complication such as decubital ulcer, dyspepsia, urinary system infection, pneumonia, significant to the raising of the psychology of paralytic patient, physiological rehabilitation and basic self care ability.

The specific embodiment
Below in conjunction with the specific embodiment this utility model is carried out detailed explanation.
It is inboard that the described mutual swing type of this utility model joint is installed in the bilateral above-knee orthosis, utilizes staple, fixes through some jam plate fixing holes 8 and the above-knee orthosis that is provided with on the jam plate 6.Said joint is provided with the U-shaped rotating turret 2 that Open Side Down, is provided with two engaged gears 1 in its U-lag, and the axial both sides of each gear 1 are respectively arranged with a rotor plate 3, adds up to 4 rotor plates 3.Rotor plate 3 is the on-plane surface member, and the distance up and down of two relative rotor plates 3 is inconsistent, and the relative distance of bottom forms the mechanical angle that meets the both legs walking greater than the relative distance on top.Two rotor plates 3 of each gear 1 and its axial both sides are connected on the rotating turret 2 through end face bearing 9.Two rotor plates 3 that are positioned at two gear 1 homonymies are connected with same jam plate seat 5 through an axle 4 separately.
The jam plate seat 5 in joint is connected with jam plate 6 through jam plate assembly 7, and detachable.Jam plate 6 is provided with jam plate fixing hole 8, through fixtures such as staples this swing type joint and bilateral above-knee orthosis is linked and packed into paraplegia walking orthosis.
Central line distance between two end face bearings 9 is 25mm; Central line distance between two axles 4 is 34mm; Vertical dimension between the line of centres of the line of centres of two end face bearings 9 and two axles 4 is 49mm, and two end face bearings 9, two axles 4 and two rotor plates 3 that are positioned at homonymy have formed the structure of four link type.Because the distance of the central line between two axles 4 is greater than the central line distance between two end face bearings 9; Be positioned at the end face bearing that is connected with same rotor plate 39 of homonymy and two lines of axle 4 and must have intersection point; Instantaneous axis of rotation heart when this intersection point is joint motions, through the design of above size, the position of this instantaneous axis of rotation heart and physiology hip joint is corresponding; General joint wants high, and rotation will be consistent with the flexion and extension in the joint of patient own.When patient's one leg moves; This side above-knee orthosis affects fixed jam plate 6 and jam plate seat 5 on it, thereby drives the mass motion of the quadric chain of this side, under the effect of two gears 1; The mass motion of the quadric chain of opposite side; Move round about through jam plate 6 and the above-knee orthosis that jam plate seat 5 drives on other one leg, form the interactive mode swing of the form of taking a step, auxiliary patient takes a step to move.And uniaxial joint center position in the past is lower, is positioned at the line midpoint of two end face bearings 9.
Stand when the patient puts on orthosis, hand steered parallel bars, center of gravity reach, health be left-leaning, makes right lower limb built on stilts, under gravity and action of inertia, right lower limb just can be swung forward and take a step.Otherwise health inclination to the right, left lower limb is liftoff, can take a step forward equally, so repeats to hocket, and walking can realize taking a step.
When patient's desire was decomposed the orthosis dismounting, the he or she extracted the flexible fastening pin on the jam plate assembly 7, touches downwards just and can orthosis be unloaded.
