Description
Technical field
The present invention relates to a kind of human synovial orthosis, especially a kind of orthopaedic device for knee
Background technology
Lower limb disability patient and knee joint obstacle crowd need to have certain walking about and steadily standing, being conducive to like this patient better participates in society and improves the quality of living, orthosis general utility functions on market are more single, and the orthosis of fixed pattern is only supported the human body stance phase, can't facilitate people's walking; Adjustable chuck formula orthopaedic device for knee needs hand adjustment, troublesome poeration, the sort ofly all can't satisfy the present demand of patient, the electronics orthopaedic device for knee can be according to the gait of human body, support phase and the shaking peroid of automatic decision human body, automatically lock in the support phase, at the shaking peroid automatic unlocking, auxiliary have handicapped patient to walk.
Summary of the invention
The present invention will provide a kind of electronics orthopaedic device for knee, and support phase and stable phase that it can Intelligent Recognition patient gait are realized the sealed and release knee joint of intelligence.
To achieve these goals, technical scheme of the present invention is: a kind of electronics orthopaedic device for knee, comprise thigh holder support, circuit board mounting platform, electronic lock, lock control devices, knee joint hinge, little leg support, spring, diaphragm pressure sensor, MSP430 single-chip microcomputer, be characterized in:
Thigh holder support connects lock control system by the circuit board mounting platform, lock control devices is connected with the shank support with the knee joint hinge by electronic lock, diaphragm pressure sensor is arranged on the wearer foot, the MSP430 single-chip microcomputer is arranged on the circuit board mounting platform, electronic lock is provided with the spur rack tapered end outward, the knee joint hinge is provided with gear outward, and the spur rack tapered end is connected with electronic lock by spring, and diaphragm pressure sensor is connected with electronic lock with the MSP430 single-chip microcomputer and is connected.
When wearer is walked, the pressure signal that diaphragm pressure sensor will detect foot is converted to analog electrical signal and feeds back to the MSP430 single-chip microcomputer, the pressure that recognizes foot when the MSP430 single-chip microcomputer just sends the signal of telecommunication to electronic lock greater than the threshold value of setting, the gear that ejects spur rack tapered end and knee joint hinge is intermeshing, makes knee joint sealed.
When wearer walks on, during threshold value that the pressure that the vola is subject to is set less than the MSP430 single-chip microcomputer, MSP430 single-chip microcomputer output control number believes to electronic lock, and spur rack tapered end retraction separates with the gear of knee joint hinge, the knee joint release.
The spur rack tapered end is slidably connected by track and electronic lock.
The invention has the beneficial effects as follows:
The present invention is arranged on the wearer foot with diaphragm pressure sensor, the pressure that is subject to when the vola is converted into the signal of telecommunication, be transferred to the processing of MSP430 single-chip microcomputer by processing amplifying circuit, the MSP430 single-chip microcomputer judges that according to the content of input signal the different output signal of generation is to control the open and close of electronic lock, kneed locked and open by the open and close controlling of electronic lock, realize the kneed basic function of electronics.Solved the patient need to be always when using traditional orthopaedic device for knee fixing knee joint, the problem that causes walking disorder even can't walk is convenient to knee joint function patient early rehabilitation and the action during rehabilitation at home, and is conducive to patient recurrence society more early.When user was dressed this kind of electronics orthopaedic device for knee walking, when being in shaking peroid, sole was stressed extremely low, and knee joint is for opening pattern, and the people can swing the knee walking; When human body was in stance phase, sole was stressed larger, and knee joint is locked, and auxiliary human body is stood, and guaranteed the stability of standing.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is further illustrated.
As shown in Figure 1, 2, electronics orthopaedic device for knee of the present invention comprises thigh holder support 1, circuit board mounting platform 2, electronic lock 3, lock control devices 4, knee joint hinge 5, lattice framing 6, shank support 7, shank bracket 8, spring 10, diaphragm pressure sensor, MSP430 single-chip microcomputer etc.
Thigh holder support 1 connects lock control system 4 by circuit board mounting platform 2, lock control devices 4 is connected with the knee joint hinge by electronic lock 3 and is connected with shank support 7, diaphragm pressure sensor is arranged on the wearer foot, the MSP430 single-chip microcomputer is arranged on circuit board mounting platform 2, the outer spur rack tapered end 9 that is provided with of electronic lock 3, the outer gear that is provided with of knee joint hinge 5, spur rack tapered end 9 is connected with electronic lock 3 by spring 10, and diaphragm pressure sensor is connected with electronic lock and is connected with the MSP430 single-chip microcomputer respectively.Spur rack tapered end 9 is by track 11 and electronic lock 3 be slidably connected (Fig. 5).
when wearer is walked, the pressure that the diaphragm pressure sensor that foot is installed detects foot is converted to analog electrical signal with pressure signal and feeds back to the MSP430 single-chip microcomputer that is arranged on circuit board mounting platform 3 and process, the pressure that recognizes foot when the MSP430 single-chip microcomputer just sends the signal of telecommunication greater than the threshold value of setting ejects electronic lock 3 tapered ends, cylinder of electronic lock has spur rack tapered end 9 outward, can slide flexibly in track 11 (seeing accompanying drawing 5), after tapered end stretches out, withstand spur rack tapered end 9 and make it intermeshing with the gear of knee joint hinge 5, cause the knee joint place can't produce relative displacement so that knee joint sealed (seeing accompanying drawing 6),
Wearer walks on afterwards, the pressure that is subject to when the vola is during less than threshold value, the threshold value that sensor is set less than the MSP430 single-chip microcomputer to the signal of MSP430 single-chip microcomputer transmission, therefore the single-chip microcomputer output signal is controlled the tapered end retraction, and under the effect of spring 10, tooth bar bounces back to initial position, so spur rack tapered end 9 leaves the gear of knee joint hinge 5, so the knee joint place can produce relative displacement, thereby knee joint release (seeing accompanying drawing 3 and 4) can be moved along natural joint degree of freedom direction.
The knee joint hinge 5 of this electronics orthopaedic device for knee is made gear-like, can be intermeshing with spur rack tapered end 9, and engagement backgear tooth bar is difficult to occur relative displacement, the fixing kneed effect of realization.
The spur rack tapered end 9 of this electronics orthopaedic device for knee is connected with electronic lock 3 by spring 10, electronic lock 3 tapered ends stretch out jack-up spur rack tapered end 9 and are meshed with knee joint hinge 5, electronic lock 3 tapered ends are retracted, under the effect of spring 10, spur rack tapered end 9 is return original position, replys the degree of freedom of knee joint hinge 5.
