Description

It is a kind of based on adaptive wrist joint rehabilitation training device in parallel
Technical field
The present invention relates to rehabilitation medical instrument fields, and in particular to a kind of adaptive rehabilitation in parallel of auxiliary wrist joint rehabilitation Training device.
Background technique
Wrist joint is most complicated one of the joint of human body, and wrist joint is located at human upper limb, and wrist joint is propped up in human upper limb Support, push-and-pull etc. subject very big load in motion processes, thus in daily life with it is easily impaired in sports.In day Often play an important role in activity.With natural calamity take place frequently and the injures and deaths of contingency, carpal fracture Disease incidence also increases therewith, and furthermore the aggravation of social senilization is so that the number of hemiplegia increases, so that wrist joint loses work Kinetic force.Therefore treatment carpal for human body is particularly important.Traditional therapeutic modality is rehabilitation therapist to patient One-to-one training is carried out, this treatment is not only expensive, expends duration, but also can neither essence during rehabilitation training True controlled training parameter and record real-time training data can not feedback training parameter and index, if treating physician passes through Deficiency is tested, or even causes secondary damage.Therefore, wrist joint rehabilitation institution is used in wrist joint rehabilitation training, not only The workload that rehabilitation training efficiency can be promoted, expensive expense is reduced, mitigate physiatrician, and can be by recording in real time Training parameter preferably feeds back the rehabilitation efficacy of patient.
Human body wrist joint healing robot is mostly that human body wrist joint model is regarded as to axis to fix and intersect universal at present Save joint.And according to human anatomy: wrist joint is one of the joint that structure is most complicated in human synovial, wrist joints sporting Not only simple ruler/oar partially, flexion/extension movement, that is to say, that wrist joint do ruler/oar partially, flexion/extension movement axis be in sky Interior movement.It immobilizes if still that ruler/oar is inclined, flexion/extension movement center of rotation is regarded as when designing convalescence device, It must cause incompatible between man-machine in rehabilitation training, may result in carpal secondary damage when serious.Cause This, design one can not only preferably resolve man-machine consistency problem, and make one in rehabilitation training more Comfortable wrist joint healing robot is significantly.
Summary of the invention
The technical problem to be solved by the present invention is to inventing one kind, to be able to satisfy wrist joint rehabilitation exercise demand (i.e. carpal Ruler partially/oar is inclined, anteflexion/to extend back movement), and during rehabilitation adaptive wrist joint axis movement so that patient is in health It is more comfortable in multiple process, natural.The device is by hand supports, top-support, side supports, the first branch, and second Chain, forearm supports, forearm support composition.The device itself has there are six freedom degree, after being clothed to human body, since wrist closes The rotational freedom for saving two broad sense limits four freedom degrees of mechanism, so that entire mechanism is clothed to only wrist after human body and closes Two broad sense rotational freedoms of section, human body after dressing close with human body wrist always during the motion for entire mechanism by its center of rotation It saves center of rotation to be overlapped, therefore the present invention preferably resolves man-machine consistency problem, makes one to feel in rehabilitation training To preferable comfort.

Specific embodiment
As Figure 1-Figure 5, the present invention is a kind based on adaptive wrist joint healing robot in parallel, has two A rotational freedom, using structure type in parallel: i.e. using the parallel institution of two driving branch UPS.The device mainly wraps Include hand supports (1), top-support (2), side supports (3), the first branch (4), the second branch (5) forearm supports (6), preceding Arm support (7).In carrying out rehabilitation training, the forearm of patient and preceding arm support (6) are tied up with elastic bands first Tie up, the hand of patient and hand supports (1) be subjected to bondage, then arm is placed on forearm support (7), carry out bondage it Before to adjust the pose of patient forearm and palm as far as possible, prevent occurring larger displacement between man-machine, make during rehabilitation Patient does not feel good, and causes secondary damage.
After convalescence device and human body bondage, forearm, which is placed on preceding arm support (7), can carry out rehabilitation training, to two Linear motor (46,56) on a driving branch (4,5) carries out driving can be so that the rotation that the device carries out both direction be transported It is dynamic, that is, the device is realized around the rotation of J1, J2 axis;Since the mechanism can keep wrist constantly during rehabilitation exercise The pivot center in joint is overlapped with the dynamic of mechanism axis of rotation, so preferably resolving man-machine consistency problem, is made one Feel more comfortable in rehabilitation training.
In summary, the rotation around J1, J2 axis may be implemented in this wrist joint healing robot, i.e. ruler/oar of wrist is inclined, Flexion/extension movement, due to ensure that carpal center of rotation is overlapped with the dynamic of mechanism center of rotation.So wrist joint rehabilitation machines Device people can effectively realize carpal rehabilitation training.
