The specific implementation mode is as follows: when the ankle orthopedic training of a patient needs to be performed, the patient needs to select the shoe body 2 with the shoe hole 23, and pass the two elastic ropes 24 at the two ends of the positioning band 20 through the shoe hole 23 respectively, and tie the elastic ropes 24 on the support buckle 25, so that the elastic ropes 24 are fixed on the support buckle 25, thereby realizing the fixed connection of the positioning band 20 on the shoe upper, meanwhile, because the support buckle 25 and the positioning band 20 are connected through the telescopic band 26, the support buckle 25 can be stretched, the positioning band 20 can be fixed on the shoe upper of different patients, meanwhile, because the positioning band 20 is provided with a plurality of fixed pulling holes 22, the positioning band 20 can also be fixed on the shoe upper through the fixed pulling holes 22, at this time, one end of the elastic band 10 is clamped into the fixing sleeve 18 through the fixing buckle 12, and because the fixing sleeve 18 is fixed on the positioning band 20 through the support frame 19, thereby realizing the fixation of one end of the elastic band 10, at this moment, paste 6 through the magic son with ankle guard body 1 and paste 7 with the magic mother and fix in patient ankle department, insert between two backup pads 8 with the joint shell 13 of the elastic band 10 other end again, press two joint poles 16 simultaneously, make two joint poles 16 receive pressure and contract each other, when joint shell 13 inserts to between two backup pads 8, at this moment, two joint poles 16 receive under buffer spring 14's the elastic force, and then stabilize two joint holes 17 departments of joint on two backup pads 8, thereby realize elastic band 10 and ankle guard body 1's quick connection, and then be convenient for patient's use, and through the joint hole 17 that is equipped with, the patient also can directly be connected elastic band 10 between fixed trompil 22 and joint hole 17, also can realize being connected between ankle guard body 1 and the locating band 20.
The method for determining the placement position of the positioning piece (5) according to the foot states of different patients is provided by simulating the plantarflexion process of the human body and combining the plurality of fixed pulling holes (22) designed by the application, and particularly relates to how to select a comfortable position (namely, a point B) from the plurality of fixed pulling holes (22) and how to adjust the ankle guard body (1) (namely, a point A).
In the process of plantarflexion of human body, the moment calculation process is as follows:
the point O is the ankle rotation center, and the coordinate of the point O is (0, 0);
point A is the position of the upper fixed point and has the coordinate of (a)1，b1)；
The point B is the position of a lower fixed point;
B1the position of the lower fixed point B when the point is the initial angle of plantarflexion;
n is the distance from the lower fixed point B to O;

at the initial angle of plantarflexion, AB1The length of (A) is as follows:
during plantarflexion, the length of AB is:
the length of the force arm OE generated by AB at the angle of onset of plantarflexion is:
the length of the moment arm OD generated by AB during plantarflexion is:
the elastic tension change function during plantarflexion is:
the moment arm changes as a function of plantarflexion:
the number of moment changes during plantarflexion is:
in the actual operation process, in addition to the above function model, in order to facilitate the operation, the fixed pulling hole 22 may be initially fixed by the elastic force and moment pattern diagram in the plantarflexion process shown in fig. 9, and after the fixing is finished, the function model may be used again to perform the final optimization in combination with the experience of the patient.
During the physiological process of plantarflexion, the elastic force of the fixing point on the instep side will always increase, and how to adjust the ankle guard body 1 (i.e. point A) is important, and the upper fixing point position point A is preferably at B1The connecting line of the point (lower fixed point) and the point O (ankle rotating center) is used as the diameter, and the formed semicircle at the instep side is close to the point O (ankle rotating center): within the semicircle, the instep elastic force arm is increased first and then decreased or increased all the time, so that the moment (elastic force arm) generated by the elastic band in the plantarflexion process is increased all the time (fig. 10), no obvious abrupt feeling exists, and the patient experience is good; the final moment is large, so that the problem that the elastic moment is too small to enable the foot to recover dorsiflexion is not easy to occur when the patient is over plantarflexion; in addition, the fixing point A is selected in the area (I) and has the protrusion of the medial malleolus and the lateral malleolus, so that the fixing point A is not easy to slide down and the trousers of the patient are not influencedThe child wears the garment.
The upper fixed point position A is less preferably at B1The connecting line of the point (lower fixed point) and the point O (ankle rotating center) is used as the diameter, and the diameter is formed at the position outside the semicircle at the instep side or far away from the point O (ankle rotating center): outside the semicircle, the instep elastic force arm is always reduced, so that the moment (elastic force arm) generated by the elastic device in the process of plantarflexion is always increased and then obviously reduced (fig. 11), and a patient has obvious sharp feeling and poor experience; the final moment is too small, even smaller than the initial moment, when the patient is over plantarflexed, the elastic moment is too small, which is not enough to recover the dorsiflexed problem of the foot, and the problem of mopping caused by foot drop can not be solved; in addition, the fixing point A is selected in the non-preferred region (II), the fixing point A is positioned at the lower leg or above, the fixing point A is easy to slide down, and the wearing selection of the trousers of the patient is relatively influenced. When the dorsal side of the foot is far away from the ankle, the elastic force changes obviously along with the plantarflexion process of the patient, and the patient feels uncomfortable due to the large pressure change at the fixing point A.
