1. Technical Field
The present invention relates to physical rehabilitation technology, and more particularly to a limb rehabilitation and training system for use in medical rehabilitation or exercise training.
2. Description of the Prior Art
A conventional limb rehabilitation and training system, as illustrated in
The aforesaid prior art limb rehabilitation and training system 10 uses the multi-axis robotic arm 11 to perform rehabilitation or training exercises, such as lifting, expanding or rotating the user's shoulder/thigh, upper limb/knee joint, forearm/calf, palm/sole or wrist/ankle joint.
The aforesaid prior art limb rehabilitation and training system 10 can achieve remarkable results in helping the user undergo limb rehabilitation or sports training, but there is still room for improvement:
1. After installation, the aforesaid prior art limb rehabilitation and training system 10 can simply be applied to train one single arm of the user, for example, as illustrated, the limb rehabilitation and training system 10 is simply applicable to the user's right arm, not rapidly adjustable for treating the user's left arm, and therefore this design of limb rehabilitation and training system 10 cannot be used in the most efficient way.
2. The multi-axis robotic arm 11 of the limb rehabilitation and training system 10 is disposed close to the back of the user's head, and the user's head can strike the multi-axis robotic arm 11 accidentally when the user expands the shoulders or arms. Thus, the user may feel fear and dare not use the limb rehabilitation and training system 10.
3. The limb rehabilitation and training system 10 must use the front three arm segments of the multi-axis robotic arm to adjust and to position the position of the user's shoulder joint. Thus, the operation is inconvenient. Further, the user's shoulder joint can easily be moved away from the set accurate position during rehabilitation or training exercises, lowering the shoulder joint, elbow joint, wrist joint or arm rehabilitation effects, and resulting in a secondary joint injury.
4. The aforesaid prior art limb rehabilitation and training system 10 does not has means for pulling stiffened joint apart, and thus the important joint mobilization in rehabilitation must be performed by a physiatrist or a physical therapist personally.
It is, therefore, the main object of the present invention to provide a limb rehabilitation and training system, which has a shoulder joint traction mechanism mounted in a multi-axis robotic arm thereof for stretching a stiffened shoulder joint of a user, loosening the shoulder joint and facilitating the performance of successive rehabilitation treatment or training.
It is another object of the present invention to provide a limb rehabilitation and training system, which is adjustable to fit the left arm and/or right arm, not only effectively enhancing the efficiency of use of the limb rehabilitation and training system but also saving resources.
It is still another object of the present invention to provide a limb rehabilitation and training system, which has the multi-axis robotic arm thereof kept away from the user's head to prevent accidental head injury during a rehabilitation or training operation, increasing user's interest in using the limb rehabilitation and training system.

Other advantages and features of the present invention will be fully understood by reference to the following specification in conjunction with the accompanying drawings, in which like reference signs denote like components of structure.
Please referring to
The horizontal position adjuster 21 comprises a horizontal linear guide 23, a horizontal positioning slide 24 mounted on (coupled to) the horizontal linear guide 23 and horizontally movable left and right on the horizontal linear guide 23.
The first arm segment robotic arm 30 comprises a horizontal bar 32 and a vertical bar 33. The horizontal bar 32 has its one end connected to the vertical bar 33, and its other end provided with an expansion rotary member 31 for enabling the user to perform shoulder expansion and/or contraction exercises. The expansion rotary member 31 can be mounted on the horizontal positioning slide 24, enabling the first arm segment robotic arm 30 to be moved with the horizontal positioning slide 24 horizontally leftward and rightwards on the horizontal linear guide 23 or rotated horizontally back and forth relative to the horizontal positioning slide 24 to expand or contract the user's shoulder. Further, the vertical bar 33 provides a vertical linear guide 35.
The height adjuster 25 comprises a height positioning slide 26, and a shoulder traction positioning guide 27 mounted at an extended location or back side of the height positioning slide 26. The height positioning slide 26 can be mounted at the vertical linear guide 35 of the first arm segment robotic arm 30, enabling the elevation of the shoulder traction positioning guide 27 of the height adjuster 25 to be adjusted subject to the user's body height.
The shoulder joint traction mechanism 40 comprises a shoulder positioning-lifting rotary member 42 connected to the height adjuster 25 for enabling the position of the user's shoulder to be adjusted forward and backward, lifted and rotated. The shoulder positioning-lifting rotary member 42 is mounted at the shoulder traction positioning guide 27 of the height adjuster 25 for allowing forward/backward adjustment of the position of the shoulder joint traction mechanism 40 within the movable range of the shoulder joint traction positioning guide 27 subject to the accurate position of the user's shoulder, shoulder joint and/or the sliding center of the shoulder joint after the user sits down or stands up.
The shoulder joint traction mechanism 40 comprises a traction displacement member 45 therein that can be linked to a upper arm positioning-lifting rotary member 53 of the upper-limb rehabilitation device 500 and carry it to move on the shoulder joint traction mechanism 40 for a separation distance d.
The traction displacement member 45 can be a traction displacement actuator or traction displacement manual manipulator. If the traction displacement member 45 is a traction displacement actuator, the upper arm positioning-lifting rotary member 53 will be controlled by a control system to perform “passive mode” displacement. On the contrary, if the traction displacement member 45 is a traction displacement manual manipulator, the upper arm positioning-lifting rotary member 53 will be manually assisted or controlled to perform “active mode” displacement.
In the successive rehabilitation or training process after the user positioned or adjusted the horizontal position adjuster 21, the height adjuster 25, the shoulder joint traction mechanism 40 and the upper-limb rehabilitation device 500, the traction displacement member 45 will carry the upper arm positioning-lifting rotary member 53 to move in the shoulder joint traction mechanism 40 for a separation distance d, or to rotate. Displacement or rotation of the upper arm positioning-lifting rotary member 53 involves shoulder joint distraction, compression or gliding, achieving joint mobilization and/or joint loosening effects, and thus this operation not only can fully loosen the user's stiffened shoulder joint, but also is conducive to the subsequent rehabilitation treatment and/or training.
In one embodiment of the present invention, the shoulder positioning-lifting rotary member 42 of the shoulder joint traction mechanism 40 not only allows adjustment of the position of the shoulder joint traction mechanism 40 relative to the height adjuster 25 but also allows performing a rotating operation of lifting up and down in a fixed position on the shoulder joint traction positioning guide 27. The shoulder joint traction mechanism 40 and the linked upper-limb rehabilitation device 500 will follow up the rotary motion of the shoulder positioning-lifting rotary member 42 to perform the rehabilitation actions of lifting up and down.
The linked upper-limb rehabilitation device 500 comprises an upper arm positioning-lifting rotary member 53 that can be linked to a simple support (not shown), or a multi-axis robotic arm as illustrated in the drawings. The multi-axis robotic arm comprises a second arm segment robotic arm 50, an elbow joint positioning link 60, a third arm segment robotic arm 70 and/or a palm rehabilitation device 80.
The second arm segment robotic arm 50 can be made, as illustrated, having an L-shaped structure. However, this L-shaped design is not a limitation. Further, the second arm segment robotic arm 50 comprises an upper arm length adjuster 57 for allowing adjustment of the length of the robotic arm subject to the length of the user's upper arm.
The upper arm positioning-lifting rotary member 53 is adapted to connect the one side of the second arm segment robotic arm 50 and connectable to the traction displacement member 45 of the shoulder joint traction mechanism 40 and movable with the traction displacement member 45 back and forth on the shoulder joint traction mechanism 40 for a separation distance d or lockable at a predetermined position. Thus, the invention not only can use a fixed position of the traction displacement member 45 as a reference point to drive the upper-limb rehabilitation device 500 and the user's shoulder joint/arm in performing the rehabilitation actions of up and down lifting rotation, but also allows forward or backward movement of the upper-limb rehabilitation device 500 for a separation distance d to drag the user's shoulder joint and to further achieve shoulder joint loosening effects subject to the assistance of the traction displacement member 45 and/or physical therapist.
An elbow twist rotary member 54 is mounted at an opposite side of the second arm segment robotic arm 50. The elbow twist rotary member 54 can be made in the form of, but not limited to, a protruding sliding block defining a guide rail or sliding groove. Alternatively, the guide rail or sliding groove can be directly made on the second arm segment robotic arm 50, eliminating the protruding sliding block.
The elbow twist rotary member 54 is adapted to connect the elbow joint positioning link 60 and to drive the upper-limb rehabilitation device 500 and the user's limbs to perform rehabilitation actions of inward and outward twisting.
The elbow joint positioning link 60 has its one end mounted with an upper arm link 63, which is adapted to connect the elbow twist rotary member 54 of the second arm segment robotic arm 50, and an arm holder 67, and its other end mounted with a forearm link 65 for connecting and holding down a forearm lifting rotary member 75 of the third arm segment robotic arm 70.
The arm holder 67 can be made in the form of, but not limited to, the illustrated C-shaped holder member for surrounding the user's arm. Alternatively, the arm holder 67 can be made in the form of a C-type motion guide or O-shaped holder member. During the rehabilitation or training process, the arm holder 67 provides a place for the resting or positioning of the user's arm along the axis of movement.
Preferably, the upper arm link 63 is mounted at the arm holder 67. The upper arm link 63 corresponds to the elbow twist rotary member 54, and can be made in the form of a guide rail or sliding groove. The upper arm link 63 and the elbow twist rotary member 54 can be joined together. Thus, the elbow joint positioning link 60, the third arm segment robotic arm 70 and/or the palm rehabilitation device 80 can achieve the rehabilitation actions of inward and outward twisting subject to the relative positioning relationship between the upper arm link 63 and the elbow twist rotary member 54.
Alternatively, the upper arm link 63 can be a component of the arm holder 67, i.e., the upper arm link 63 can be formed integral with the arm holder 67, and the elbow twist rotary member 54 can be directly connected to the arm holder 67.
The structure of the third arm segment robotic arm 70 is substantially similar to the structure of the second arm segment robotic arm 50. For example, the third arm segment robotic arm 70 can be made, as illustrated, having an L-shaped structure. However, this L-shaped design is not a limitation. Further, the third arm segment robotic arm 70 comprises a forearm length adjuster 77 for allowing adjustment of the length of the robotic arm subject to the length of the user's forearm.
The forearm lifting rotary member 75 is mounted at one end of the third arm segment robotic arm 70 and connected to the forearm link 65 of the elbow joint positioning link 60. Based on the reference point at the forearm link 65, the forearm lifting rotary member 75 can be moved to drive the third arm segment robotic arm 70 and the user's forearm and/or palm in performing the rehabilitation actions of up and down lifting rotation.
The third arm segment robotic arm 70 has its other end mounted with a wrist twist rotary member 76 for connecting the palm rehabilitation device 80 and driving the palm rehabilitation device 80 and the user's palm, wrist and/or forearm to perform the rehabilitation or training actions of inward and outward twisting.
Linking the wrist twist rotary member 76 and the palm rehabilitation device 80 not only can hold the user's palm in place but also can rehabilitate or train the functions of the user's palm.
Referring to
Alternatively, the user can select “active mode”. At this time, the user can apply force to move the limb rehabilitation and training system 20 directly or under the physiatrist, forcing the first arm segment robotic arm 30 to move the height adjuster 25, the shoulder joint traction mechanism 40, the upper-limb rehabilitation device 500, the hand grip 805 and the user's shoulder/arm horizontally leftward and rightward on the reference point of fixed location of the expansion rotary member 31, thereby achieving outward expansion or inward contraction of the shoulder.
Further, in another embodiment of the present invention, the height adjuster 25 is equipped with a shoulder joint stretching link 275 to substitute for the shoulder joint traction positioning guide 27; instead of the shoulder positioning-lifting rotary member 42, the shoulder joint traction mechanism 40 uses a shoulder positioning member 422 for fixation to the shoulder joint stretching link 275. Before operating the limb rehabilitation and training system 20, the horizontal position adjuster 21 and the height adjuster 25 are relatively adjusted subject to the accurate position of the user's shoulder or shoulder joint, or the sliding center of the user's shoulder joint when the user stands up or sits down.
The shoulder joint stretching link 275 can be, but not limited to, a locating hole, and the shoulder positioning member 422 can be a mating protruding member. On the contrary, the shoulder positioning member 422 can be a locating hole, and the shoulder joint stretching link 275 can be a mating protruding member.
Because the component parts of the limb rehabilitation and training system 20 are kept away from the user's head and the back of the user's head during operation of the limb rehabilitation and training system 20 to perform a rehabilitation process of shoulder expansion or contraction, the invention greatly reduces the risk of accidental head injury and effectively help the user from feeling oppressed when using the limb rehabilitation and training system 20, thereby increasing user's interest in using the limb rehabilitation and training system 20 and enhancing the rehabilitation effects of the limb rehabilitation and training system 20.
In still another embodiment of the present invention, the wrist twist rotary member 76 is directly connected with a hand grip 805 to substitute for the aforesaid palm rehabilitation device 80 for holding or supporting the user's palm.
Referring to
In one embodiment of the present invention, during the operation of moving the upper-limb rehabilitation device 500 and the user's arm up and down, the traction displacement member 45 of the shoulder joint traction mechanism 40 will also move the upper-limb rehabilitation device 500 and the user arm transiently forward or backward for a separation distance d to loosen or stretch the user's shoulder joint.
Referring to
Thereafter, based on the reference point at the expansion rotary member 31, the first arm segment robotic arm 30, the height adjuster 25 and the upper-limb rehabilitation device 500 are rotated horizontally outward at an angle of 180-degrees, and then rotated vertically at an angle of 180 degrees on the reference point of the shoulder positioning-lifting rotary member 42 of the shoulder joint traction mechanism 40, or the shoulder positioning member 422, or the upper arm positioning-lifting rotary member 53 of the upper-limb rehabilitation device 500. Thus, the first arm segment robotic arm 30, the height adjuster 25, the shoulder joint traction mechanism 40 and the upper-limb rehabilitation device 500 are changed into a rehabilitation and training system for exercising the user or patient's right arm.
Because the invention allows one same system to be easily and rapidly changed for treating the left arm or right arm in response to the actual needs of the user, the invention greatly increases the efficiency of use of the limb rehabilitation and training system, reducing material waste generated during manufacturing.
Referring to
Referring to
By means of relative position adjustment of the aforesaid component parts, the limb rehabilitation and training system is configured to fit the body size of every different user, reducing the risk of accidental secondary injury during rehabilitation.
Further, in one embodiment of the present invention, a bearing platform 879 is provided at the bottom side of the movable base 87 to carry the horizontal position adjuster 21. Thus, by means of moving the movable base 87, the limb rehabilitation and training system 20 can be transferred to the desired place, facilitating a user or patient to use the system.
Further,
To accurately adjust the optimal position of every component part of the limb rehabilitation and training system 20, the adjustment operation can be done by a physiatrist, physical therapist, medical personnel or trainer. However, in some special occasions, it may be unable to find a professional therapist to adjust the machine. The invention eliminates this problem by providing one or multiple localized video recorders 81 selectively mounted at the height adjuster 25, the shoulder joint traction mechanism 40, the elbow joint positioning link 60 and/or the upper-limb rehabilitation device 500 for picking up every important part of the user's arm and transmitting fetched video data to the control system 90, which calculates the video data to find out the optimal component position data 93 of every component part of the limb rehabilitation and training system 20.
Of course, the component position data 93 can be obtained subject to the rehabilitation plan or body size of the individual user arranged or measured by a physiatrist, physical therapist, medical personnel or trainer.
The component position data 93, control data 91 and/or rehabilitation data 92 can be displayed on a display screen (not shown), and the user or assistant can use this data to adjust the best configuration of the limb rehabilitation and training system 20 for the user.
Further, in still another alternate form of the present invention, as shown in
Further, in order to prevent accidental injury of the shoulder joint, elbow joint and/or wrist joint during a rehabilitation operation, the invention provides one or multiple joint positioning guards, for example, a shoulder joint positioning guard 83, an elbow joint positioning guard 84 and/or a wrist joint positioning guard 82 wearable on the user's shoulder, elbow and/or wrist. Every joint positioning guard 82/83/84 provides one or multiple position sensing points 85 that can be fetched by the localized video recorder 81 and the control system 90 through an optical path, infrared path and/or wireless signal transmission path for figuring out the location of the user's shoulder and every part or joint of the user's arm and the desired component position data 93. Thus, the invention greatly shortens the adjustment time of the limb rehabilitation and training system 20 and reduces the risk of accidental rehabilitation injury.
Further, in still another alternate form of the present invention, one or multiple potentiometers 95 and force sensors 97 can be installed in the expansion rotary member 31, the shoulder positioning-lifting rotary member 42 or one or multiple component parts of the upper-limb rehabilitation device 500, and electrically connected to the control system 90.
The potentiometer 95 is adapted to detect the relative adjustment position of the expansion rotary member 31, the shoulder positioning-lifting rotary member 42 or the upper-limb rehabilitation device 500. The force sensor 97 can detect the pressure being applied to the expansion rotary member 31, the shoulder positioning-lifting rotary member 42 or the upper-limb rehabilitation device 500. These detected data are transmitted to the control system 90 for recording, facilitating physiatrist, physical therapist, medical personnel or trainer reference, and thus the physiatrist, physical therapist, medical personnel or trainer can master the rehabilitation or training program and figure out whether or not the user or patient has been well rehabilitated or trained, and then put the user in mind. These detected data could become future rehabilitation data 92 or control data 91.
Finally, see
Further, in one embodiment of the present invention, the user can directly adjust the standing or sitting position. In this embodiment, the horizontal position adjuster 21 is eliminated, and the first arm segment robotic arm 30 simply has the vertical bar 33 and/or the vertical linear guide 35 left for application. This embodiment eliminates the use of the horizontal position adjuster 21, however subject to the use of the shoulder joint traction mechanism 40 and the upper-limb rehabilitation device 500, the object of loosening or stretching the shoulder joint can still be achieved.
Further, every movable component part 24/26/45, every guide 23/27, the upper arm length adjuster 57, the forearm length adjuster 77, the elbow twist rotary member 54 or the forearm link 65 in the aforesaid embodiments or drawings is made in the form of a sliding block, guide groove, sliding groove or guide rail. However, the use of the aforesaid component parts is not a limitation. Gear, chains, conveyer belt, elastic member, or any other equivalent device can be used as a substitute.
Further, in still another alternate form of the present invention, the elbow twist rotary member 54 can be a protruding member extended from one end of the second arm segment robotic arm 50, and a mating upper arm link 635, for example, a coupling hole can be provided at the front side of the elbow joint positioning link 60 to substitute for the aforesaid guide rail or sliding groove 63 at the arm holder 67. By means of coupling between the elbow twist rotary member 54 and the upper arm link 635, the second arm segment robotic arm 50 and the elbow joint positioning link 60 are connected together, allowing rotation of the elbow joint positioning link 60 and the upper-limb rehabilitation device 500.
In the foresaid embodiments or drawings, the limb rehabilitation and training system is described for exercising the user's upper limb, shoulder joint, elbow or wrist. Actually, the limb rehabilitation and training system can also be used to perform the rehabilitation and training program of exercising the user's lower limb, thigh, knee joint or ankle joint.
In the specification of the present invention, the wordings of may, must and change are not intended to restrict the invention. The terminologies used in the specification are used to describe particular embodiments of the invention, but not intended for use as restrictions. For example, the word of “link”, can be “connected together”, “sleeved together” or “engaged together” that is understandable to any person skilled in the art who examined the present specification and the annexed drawings. Further, a single quantifier (such as one or the) used in the specification can be multiple unless specifically described in the specification.
