It is realized by way of opening up long slot hole and pin shaft matches, and carries out relatively fixed, third by means of third lockable mechanism
Lockable mechanism can be nut locking form, however it is not limited to this form, anyone skilled in the art it is conceivable that realization
Form is within the present embodiment protection scope.
Further, it please refers to and present embodiments provides two kinds of open limbs shown in Fig. 1, Fig. 2, Fig. 4, Fig. 5, Figure 11, Figure 12
The embodiment of section pushing ram 1, respectively double rod and single pole, both can be used.
Further, it please refers to the present embodiment shown in Fig. 9, Figure 10 and additionally provides the preferred implementation shape of the first lockable mechanism
Formula, specifically, the first lockable mechanism include the static tooth plate 8 being fixedly arranged on closing limb section fixed part, are fixedly arranged on open limb section propulsion
Active toothed disk 9 on bar 1, the static tooth plate 8 and active toothed disk 9 align and are equipped with axis 10, the static tooth plate 8 with it is described in
Axis 10 is fixedly connected, and the active toothed disk 9 is slidably connected with axis 10, and 10 end of axis is additionally provided with for ejection active toothed disk 9
With the engagement of static tooth plate 8 or isolated transposition control lock 11.
In the present embodiment, when active toothed disk 9 is not engaged with static tooth plate 8, active toothed disk 9 can be on axis 10
Rotation and sliding, rotation then drive open limb section pushing ram 1 to rotate, reach the open curved effect of limb section, when the certain angle of rotation
After degree, after open limb section bending degree reaches standard, then transposition control lock 11 is operated, so that it is carried out ejection to active toothed disk 9 makes it
It is moved to the degree engaged with static tooth plate 8, then active toothed disk 9 is fixed, and open limb section pushing ram 1 is also stationary, otherwise grasps again
Rotate control lock 11, releases the ejection to active toothed disk 9, then active toothed disk 9 discharges, and open limb section pushing ram 1 can continue to rotate,
Transposition control lock 11 is located at 10 end of axis, and is rotatablely connected with axis 10, can be right to its lug boss when turning to a certain position
Active toothed disk 9 causes ejection, goes back to lug boss when coming and releases ejection, there are also the effects for stopping active toothed disk 9 to fall off from axis 10.
Further, it please refers to shown in Fig. 6, Fig. 7, Fig. 8, present embodiments provides the preferred embodiment of air bag 2, specifically
Ground, the air bag 2 are made of the seperated capsule of interconnected three for enumerating arrangement.The form being overlapped mutually using three seperated capsules
Open ended tolerance is considerably increased, so that swelling volume becomes larger, it is also further to the ejection dynamics and range of the open limb section of people
It increases.
Further, on how to being inflated to air bag 2, present embodiments providing ventilating control mechanism is with supplying gas
Supply gas manually capsule 12 or the electronic air feeder structure 20 of pipe.It can realize the quantitative inflation to air bag 2.Capsule 12 of supplying gas manually passes through
Snorkel connect with air bag 2 and is equipped with snorkel prevents airflow reflux and relief valve from preventing pressure excessive equipped with check-valves.
Further, it please refers to shown in Fig. 3, the present embodiment further provides the preferred implementation side of electronic air feeder structure 20
Formula, specifically, electronic air feeder structure 20 include micro air pump 13, the tracheae 14 of connection micro air pump 13 and air bag 2, detection tracheae
The vent valve 16 of the pressure sensor 15, connectivity trachea 14 of pressure in 14, the pressure adjustment knob 17 for adjusting 16 aperture of vent valve,
The micro air pump 13 is controlled by master controller 18, the letter of the signal output end connection master controller 18 of the pressure sensor 15
Number input terminal.The design form that 20 parallel connection of capsule 12 and electronic air feeder structure of supplying gas manually is used in Figure 11 and Figure 12, may be selected
Using one of those, parallel form can not also be used, one of use directly is chosen.
In the present embodiment, inflation pressure has been previously set according to patient's knee/elbow joint activity condition in master controller 18
Force value, the i.e. swell value of air bag 2 are inflated by controlling micro air pump 13, then stop inflating after reaching setting value, or
Can be according to the pressure value of pressure sensor 15 come the control for the amount of being inflated, general patient has one to quantify universal fill
Gas value delivers a signal to master controller 18 after pressure sensor 15 obtains this charged value by detection pressure, then stops filling
Gas is further provided with vent valve 16, if inflation is excessive, patient pain unbearably, then deflate by rotation pressure adjusting knob 17
Operation.
