Background technology
Stroke hemiplegia lower limb often show as flexing spasm pattern, ankle plantar flexion of foot Varus deformity, ankle dorsiflexion deficiency, step
Be rendered as during row draw circle a gait, tibialis anterior is powerless after fracture patient causes common peroneal nerve injury, ankle dorsiflexion can not, show as foot
Hang down, have a strong impact on patient's walking gait, clinically use ankle-foot orthosis (ankle foot orthosis, AFO) and rectified
Just.AFO can correct and prevent patient's contracture of Achilles tendon, can partly improve the stability of patient's walking gait, recover to some extent
Patient's walking ability, extensively in clinical application.Although dynamic ankle AFO can allow some patientss to play itself ankle dorsiflexion function,
But ankle-joint plantar flexion function is limited, has some patientss ankle dorsiflexion itself powerless, can not play ankle in the normal gait cycle
Dorsiflexion function.
The content of the invention
The purpose of the present invention is exactly in order to solve the above-mentioned technical problem, and to provide a kind of knee power radian pulley-type drop foot
And hemiplegic gait rectifier.
The present invention includes above-knee thigh straightening members, thigh straightening mechanism fixture, shank straightening members, shank correction structure
Part fixture, crank levers component, footrest connecting rope and footrest, above-knee thigh straightening members and shank the straightening members difference
Provided with openend, the both sides of the openend are connected and installed with thigh straightening mechanism fixture respectively and shank straightening members are fixed
Part, the crank levers component include crank levers, crank levers rotary shaft and for limiting crank levers mobile space one
To pulley, one end of the crank levers is provided with shaft mounting hole, and the other end is tethered at hole provided with connecting rope, the crank levers
The shaft mounting hole of one end may be rotatably mounted on above-knee thigh straightening members by crank levers rotary shaft, the pair of pulley
Be movably arranged on respectively by rotating shaft on shank straightening members, be stuck in the middle part of the crank levers rotary shaft a pair of pulleys it
Between, the connecting rope that one end of the footrest connecting rope ties up to crank levers is tethered at hole, and the footrest is connected to footrest connecting rope
The other end.
Low temperature thermoplastic plate mould molding is respectively adopted in the thigh straightening members, shank straightening members and footrest.
Also described thigh straightening mechanism fixture and shank straightening members fixture are VELCRO respectively.
The footrest connecting rope uses stretch cord.
The footrest connecting rope uses non-stretchable rope.
The present invention has advantages below：
The present invention is passively or actively knee sprung by hip flexing and provides driving force, on the outside of knee joint, across knee joint
By single-ended on-fixed crank sliding lever in front side of shin bone space (pressing close to shin bone), there is provided substitute tibialis anterior concentric contraction function
The driving force of (ankle dorsiflexion), fixed crank lever front side of shin bone end and preceding dorsal portion are distinguished by rope, preceding dorsal portion is by rectifying
Shape device anchor line one end, rehabilitation training effectively can be carried out to stroke hemiplegia lower limb, correct patient's gait.

Embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, the present invention includes above-knee thigh straightening members 1, thigh straightening mechanism fixture 2, shank correction
Component 3, shank straightening members fixture 4, crank levers component, footrest connecting rope 5 and footrest 6, the above-knee thigh correction structure
Part 1 and shank straightening members 3 are respectively equipped with openend, and the both sides of the openend are connected and installed with thigh straightening mechanism and consolidated respectively
Determine part 2 and shank straightening members fixture 4, the crank levers component includes crank levers 7, crank levers rotary shaft 8 and used
In a pair of the pulleys 9 for limiting crank levers mobile space, one end of the crank levers 7 is provided with shaft mounting hole, and the other end is set
There is connecting rope to be tethered at hole, the shaft mounting hole of one end of the crank levers 7 may be rotatably mounted at by crank levers rotary shaft 8
On above-knee thigh straightening members 1, the pair of pulley 9 is movably arranged on shank straightening members 3 by rotating shaft respectively, the song
The middle part of handle lever rotation axle 8 is stuck between a pair of pulleys 9, and one end of the connecting rope 5 of footrest 6 ties up to the company of crank levers 7
Splicing is tethered at hole, and the footrest 6 is connected to the other end of footrest connecting rope 5.
Low temperature thermoplastic plate mould molding is respectively adopted in the thigh straightening members 1, shank straightening members 3 and footrest 6.
Also described thigh straightening mechanism fixture 2 and shank straightening members fixture 4 are VELCRO respectively.
The footrest connecting rope 5 uses stretch cord.
The footrest connecting rope 5 uses non-stretchable rope.
Working method and principle, the present invention carry out the making of gait correcting device using following steps：
Step 1：Above-knee 20cm measures thigh circumference degree, and above-knee thigh straightening members are made using low temperature thermoplastic plate, be open to
Interior (VELCRO is fixed, adjusting elasticity), above-knee thigh straightening members middle part crank levers rotary shaft installation；
Step 2：10cm measures calf circumference degree under capitulum fibulae, and shank straightening members, opening are made using low temperature thermoplastic plate
Inwardly (VELCRO is fixed, adjusting elasticity), a pair of pulleys of shank straightening members middle part installation crank levers above and below, limit
System and control crank levers move up space when sliding；
Step 3：Crank levers length and arc measurement：To calf at above-knee 20cm when 0 degree of knee is stretched in measurement on the outside of the knee joint
Length under capitellum at 10cm is realized by the regulation to crank levers distal end radian size and gone down on one's knees 90 degree as lever length
When, crank levers protrude anterior border of tibia vertical range 3-5cm；Lever near-end makes rotary shaft, and distal bore is used to be tethered at footrest
Connecting rope；
Step 4：Made by low temperature thermoplastic plate and rope anchor is made in the middle part of front foot (articulationes metatarsophalangeae) back KAFO (footrest)
Determine part；
Step 5：Stretch 0 degree of knee, 0 degree of ankle-joint erect position, measurement footrest connecting rope length and stationary rope both ends；
Step 6：Above-knee thigh straightening members, shank straightening members and footrest are worn on the thigh, shank and foot of people respectively
Portion, rehabilitation walking is carried out, rope lengths will be adjusted according to walking gait analysis.
Embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, about the common of technical field
Technical staff, without departing from the spirit and scope of the present invention, it can also make a variety of changes and modification, thus it is all
Equivalent technical scheme falls within scope of the invention, and scope of patent protection of the invention should be defined by the claims.
